Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Commit pf version 3.5 and link additional files to the kernel build. Version 3.5 brings: - Atomic commits of ruleset changes (reduce the chance of ending up in an inconsistent state). - A 30% reduction in the size of state table entries. - Source-tracking (limit number of clients and states per client). - Sticky-address (the flexibility of round-robin with the benefits of source-hash). - Significant improvements to interface handling. - and many more ...

o Create directory sys/netpfil, where all packet filters should reside, and move there ipfw(4) and pf(4). o Move most modified parts of pf out of contrib. Actual movements: sys/contrib/pf/net/*.c -> sys/netpfil/pf/ sys/contrib/pf/net/*.h -> sys/net/ contrib/pf/pfctl/*.c -> sbin/pfctl contrib/pf/pfctl/*.h -> sbin/pfctl contrib/pf/pfctl/pfctl.8 -> sbin/pfctl contrib/pf/pfctl/*.4 -> share/man/man4 contrib/pf/pfctl/*.5 -> share/man/man5 sys/netinet/ipfw -> sys/netpfil/ipfw The arguable movement is pf/net/*.h -> sys/net. There are future plans to refactor pf includes, so I decided not to break things twice. Not modified bits of pf left in contrib: authpf, ftp-proxy, tftp-proxy, pflogd. The ipfw(4) movement is planned to be merged to stable/9, to make head and stable match. Discussed with: bz, luigi

Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

Complete break-out of sys/sys/mac.h into sys/security/mac/mac_framework.h begun with a repo-copy of mac.h to mac_framework.h. sys/mac.h now contains the userspace and user<->kernel API and definitions, with all in-kernel interfaces moved to mac_framework.h, which is now included across most of the kernel instead. This change is the first step in a larger cleanup and sweep of MAC Framework interfaces in the kernel, and will not be MFC'd. Obtained from: TrustedBSD Project Sponsored by: SPARTA

Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

static void pf_send_tcp(struct mbuf *,
Introduce a new entry point, mac_create_mbuf_from_firewall. This entry point exists to allow the mandatory access control policy to properly initialize mbufs generated by the firewall. An example where this might happen is keep alive packets, or ICMP error packets in response to other packets. This takes care of kernel panics associated with un-initialize mbuf labels when the firewall generates packets. [1] I modified this patch from it's original version, the initial patch introduced a number of entry points which were programmatically equivalent. So I introduced only one. Instead, we should leverage mac_create_mbuf_netlayer() which is used for similar situations, an example being icmp_error() This will minimize the impact associated with the MFC Submitted by: mlaier [1] MFC after: 1 week This is a RELENG_6 candidate

Import pf.c 1.635 and pf_lb.c 1.4 from OpenBSD Stricter state checking for ICMP and ICMPv6 packets: include the ICMP type in one port of the state key, using the type to determine which side should be the id, and which should be the type. Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

When connection rate hits and we overload a source to a table, we are actually editing table, which means editing rules, thus we need writer access to 'em. Fix this by offloading the update of table to the same taskqueue, we already use for flushing. Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

static int pf_insert_src_node(struct pf_src_node **,
struct pf_rule *, struct pf_addr *, sa_family_t);
Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

Import pf.c 1.635 and pf_lb.c 1.4 from OpenBSD Stricter state checking for ICMP and ICMPv6 packets: include the ICMP type in one port of the state key, using the type to determine which side should be the id, and which should be the type. Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

Version 3.5 brings: - Atomic commits of ruleset changes (reduce the chance of ending up in an inconsistent state). - A 30% reduction in the size of state table entries. - Source-tracking (limit number of clients and states per client). - Sticky-address (the flexibility of round-robin with the benefits of source-hash). - Significant improvements to interface handling. - and many more ...

Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s.

When connection rate hits and we overload a source to a table, we are actually editing table, which means editing rules, thus we need writer access to 'em. Fix this by offloading the update of table to the same taskqueue, we already use for flushing. Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

if (!rule->max_src_nodes ||
Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s. Thanks to Dennis for providing me shell access to problematic box and his help with reproducing, debugging and investigating the problem.

Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s. Thanks to Dennis for providing me shell access to problematic box and his help with reproducing, debugging and investigating the problem.

if (src->rule.ptr)
Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s.

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

When connection rate hits and we overload a source to a table, we are actually editing table, which means editing rules, thus we need writer access to 'em. Fix this by offloading the update of table to the same taskqueue, we already use for flushing. Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

When connection rate hits and we overload a source to a table, we are actually editing table, which means editing rules, thus we need writer access to 'em. Fix this by offloading the update of table to the same taskqueue, we already use for flushing. Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

PF_HASHROW_UNLOCK(ih);
Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Improve locking strategy between keys hash and ID hash. Before this change state creating sequence was: 1) lock wire key hash 2) link state's wire key 3) unlock wire key hash 4) lock stack key hash 5) link state's stack key 6) unlock stack key hash 7) lock ID hash 8) link into ID hash 9) unlock ID hash What could happen here is that other thread finds the state via key hash lookup after 6), locks ID hash and does some processing of the state. When the thread creating state unblocks, it finds the state it was inserting already non-virgin. Now we perform proper interlocking between key hash locks and ID hash lock: 1) lock wire & stack hashes 2) link state's keys 3) lock ID hash 4) unlock wire & stack hashes 5) link into ID hash 6) unlock ID hash To achieve that, the following hacking was performed in pf_state_key_attach(): - Key hash mutex is marked with MTX_DUPOK. - To avoid deadlock on 2 key hash mutexes, we lock them in order determined by their address value. - pf_state_key_attach() had a magic to reuse a > FIN_WAIT_2 state. It unlinked the conflicting state synchronously. In theory this could require locking a third key hash, which we can't do now. Now we do not remove the state immediately, instead we leave this task to the purge thread. To avoid conflicts in a short period before state is purged, we push to the very end of the TAILQ. - On success, before dropping key hash locks, pf_state_key_attach() locks ID hash and returns.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

void
pf_purge_thread(void *v)
{
Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

/*

Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

(V_pf_default_rule.timeout[PFTM_INTERVAL] * 10));
/* Purge other expired types every PFTM_INTERVAL seconds. */
Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

KASSERT((state->timeout < PFTM_MAX),
Update packet filter (pf) code to OpenBSD 4.5. You need to update userland (world and ports) tools to be in sync with the kernel. Submitted by: mlaier Submitted by: eri

start = state->rule.ptr->timeout[PFTM_ADAPTIVE_START];
if (start) {
end = state->rule.ptr->timeout[PFTM_ADAPTIVE_END];
Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s. Thanks to Dennis for providing me shell access to problematic box and his help with reproducing, debugging and investigating the problem.

The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

To support upcoming changes change internal API for source node handling: - Removed pf_remove_src_node(). - Introduce pf_unlink_src_node() and pf_unlink_src_node_locked(). These function do not proceed with freeing of a node, just disconnect it from storage. - New function pf_free_src_nodes() works on a list of previously disconnected nodes and frees them. - Utilize new API in pf_purge_expired_src_nodes().

Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s. Thanks to Dennis for providing me shell access to problematic box and his help with reproducing, debugging and investigating the problem.

STATE_DEC_COUNTERS(s);
Rule memory garbage collecting in new pf scans only states that are on id hash. If a state has been disconnected from id hash, its rule pointers can no longer be dereferenced, and referenced memory can't be modified. Thus, move rule statistics from pf_free_rule() to pf_unlink_rule() and update them prior to releasing id hash slot lock. Reported by: Ian FREISLICH <ianf cloudseed.co.za>

Close possible races between state deletion and sent being sent out from pfsync: - Call into pfsync_delete_state() holding the state lock. - Set the state timeout to PFTM_UNLINKED after state has been moved to the PFSYNC_S_DEL queue in pfsync. Reported by: Ian FREISLICH <ianf cloudseed.co.za>

Rule memory garbage collecting in new pf scans only states that are on id hash. If a state has been disconnected from id hash, its rule pointers can no longer be dereferenced, and referenced memory can't be modified. Thus, move rule statistics from pf_free_rule() to pf_unlink_rule() and update them prior to releasing id hash slot lock. Reported by: Ian FREISLICH <ianf cloudseed.co.za>

/*
* Called only from pf_purge_thread(), thus serialized.
*/
Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

PF_HASHROW_UNLOCK(ih);
Simplify and somewhat redesign interaction between pf_purge_thread() and pf_purge_expired_states(). Now pf purging daemon stores the current hash table index on stack in pf_purge_thread(), and supplies it to next iteration of pf_purge_expired_states(). The latter returns new index back. The important change is that whenever pf_purge_expired_states() wraps around the array it returns immediately. This makes our knowledge about status of states expiry run more consistent. Prior to this change it could happen that n-th run stopped on i-th entry, and returned (1) as full run complete, then next (n+1) full run stopped on j-th entry, where j < i, and that broke the mark-and-sweep algorythm that saves references rules. A referenced rule was freed, and this later lead to a crash.

When connection rate hits and we overload a source to a table, we are actually editing table, which means editing rules, thus we need writer access to 'em. Fix this by offloading the update of table to the same taskqueue, we already use for flushing. Since taskqueues major task is now overloading, and flushing is optional, do mechanical rename s/flush/overload/ in the code related to the taskqueue. Since overloading tasks do unsafe referencing of rules, provide a bandaid in pf_purge_unlinked_rules(). If the latter sees any queued tasks, then it skips purging for this run. In table code: - Assert any lock in pfr_lookup_addr(). - Assert writer lock in pfr_route_kentry().

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Introduce a new entry point, mac_create_mbuf_from_firewall. This entry point exists to allow the mandatory access control policy to properly initialize mbufs generated by the firewall. An example where this might happen is keep alive packets, or ICMP error packets in response to other packets. This takes care of kernel panics associated with un-initialize mbuf labels when the firewall generates packets. [1] I modified this patch from it's original version, the initial patch introduced a number of entry points which were programmatically equivalent. So I introduced only one. Instead, we should leverage mac_create_mbuf_netlayer() which is used for similar situations, an example being icmp_error() This will minimize the impact associated with the MFC Submitted by: mlaier [1] MFC after: 1 week This is a RELENG_6 candidate

Introduce a new entry point, mac_create_mbuf_from_firewall. This entry point exists to allow the mandatory access control policy to properly initialize mbufs generated by the firewall. An example where this might happen is keep alive packets, or ICMP error packets in response to other packets. This takes care of kernel panics associated with un-initialize mbuf labels when the firewall generates packets. [1] I modified this patch from it's original version, the initial patch introduced a number of entry points which were programmatically equivalent. So I introduced only one. Instead, we should leverage mac_create_mbuf_netlayer() which is used for similar situations, an example being icmp_error() This will minimize the impact associated with the MFC Submitted by: mlaier [1] MFC after: 1 week This is a RELENG_6 candidate

Add code to allow the system to handle multiple routing tables. This particular implementation is designed to be fully backwards compatible and to be MFC-able to 7.x (and 6.x) Currently the only protocol that can make use of the multiple tables is IPv4 Similar functionality exists in OpenBSD and Linux. From my notes: ----- One thing where FreeBSD has been falling behind, and which by chance I have some time to work on is "policy based routing", which allows different packet streams to be routed by more than just the destination address. Constraints: ------------ I want to make some form of this available in the 6.x tree (and by extension 7.x) , but FreeBSD in general needs it so I might as well do it in -current and back port the portions I need. One of the ways that this can be done is to have the ability to instantiate multiple kernel routing tables (which I will now refer to as "Forwarding Information Bases" or "FIBs" for political correctness reasons). Which FIB a particular packet uses to make the next hop decision can be decided by a number of mechanisms. The policies these mechanisms implement are the "Policies" referred to in "Policy based routing". One of the constraints I have if I try to back port this work to 6.x is that it must be implemented as a EXTENSION to the existing ABIs in 6.x so that third party applications do not need to be recompiled in timespan of the branch. This first version will not have some of the bells and whistles that will come with later versions. It will, for example, be limited to 16 tables in the first commit. Implementation method, Compatible version. (part 1) ------------------------------- For this reason I have implemented a "sufficient subset" of a multiple routing table solution in Perforce, and back-ported it to 6.x. (also in Perforce though not always caught up with what I have done in -current/P4). The subset allows a number of FIBs to be defined at compile time (8 is sufficient for my purposes in 6.x) and implements the changes needed to allow IPV4 to use them. I have not done the changes for ipv6 simply because I do not need it, and I do not have enough knowledge of ipv6 (e.g. neighbor discovery) needed to do it. Other protocol families are left untouched and should there be users with proprietary protocol families, they should continue to work and be oblivious to the existence of the extra FIBs. To understand how this is done, one must know that the current FIB code starts everything off with a single dimensional array of pointers to FIB head structures (One per protocol family), each of which in turn points to the trie of routes available to that family. The basic change in the ABI compatible version of the change is to extent that array to be a 2 dimensional array, so that instead of protocol family X looking at rt_tables[X] for the table it needs, it looks at rt_tables[Y][X] when for all protocol families except ipv4 Y is always 0. Code that is unaware of the change always just sees the first row of the table, which of course looks just like the one dimensional array that existed before. The entry points rtrequest(), rtalloc(), rtalloc1(), rtalloc_ign() are all maintained, but refer only to the first row of the array, so that existing callers in proprietary protocols can continue to do the "right thing". Some new entry points are added, for the exclusive use of ipv4 code called in_rtrequest(), in_rtalloc(), in_rtalloc1() and in_rtalloc_ign(), which have an extra argument which refers the code to the correct row. In addition, there are some new entry points (currently called rtalloc_fib() and friends) that check the Address family being looked up and call either rtalloc() (and friends) if the protocol is not IPv4 forcing the action to row 0 or to the appropriate row if it IS IPv4 (and that info is available). These are for calling from code that is not specific to any particular protocol. The way these are implemented would change in the non ABI preserving code to be added later. One feature of the first version of the code is that for ipv4, the interface routes show up automatically on all the FIBs, so that no matter what FIB you select you always have the basic direct attached hosts available to you. (rtinit() does this automatically). You CAN delete an interface route from one FIB should you want to but by default it's there. ARP information is also available in each FIB. It's assumed that the same machine would have the same MAC address, regardless of which FIB you are using to get to it. This brings us as to how the correct FIB is selected for an outgoing IPV4 packet. Firstly, all packets have a FIB associated with them. if nothing has been done to change it, it will be FIB 0. The FIB is changed in the following ways. Packets fall into one of a number of classes. 1/ locally generated packets, coming from a socket/PCB. Such packets select a FIB from a number associated with the socket/PCB. This in turn is inherited from the process, but can be changed by a socket option. The process in turn inherits it on fork. I have written a utility call setfib that acts a bit like nice.. setfib -3 ping target.example.com # will use fib 3 for ping. It is an obvious extension to make it a property of a jail but I have not done so. It can be achieved by combining the setfib and jail commands. 2/ packets received on an interface for forwarding. By default these packets would use table 0, (or possibly a number settable in a sysctl(not yet)). but prior to routing the firewall can inspect them (see below). (possibly in the future you may be able to associate a FIB with packets received on an interface.. An ifconfig arg, but not yet.) 3/ packets inspected by a packet classifier, which can arbitrarily associate a fib with it on a packet by packet basis. A fib assigned to a packet by a packet classifier (such as ipfw) would over-ride a fib associated by a more default source. (such as cases 1 or 2). 4/ a tcp listen socket associated with a fib will generate accept sockets that are associated with that same fib. 5/ Packets generated in response to some other packet (e.g. reset or icmp packets). These should use the FIB associated with the packet being reponded to. 6/ Packets generated during encapsulation. gif, tun and other tunnel interfaces will encapsulate using the FIB that was in effect withthe proces that set up the tunnel. thus setfib 1 ifconfig gif0 [tunnel instructions] will set the fib for the tunnel to use to be fib 1. Routing messages would be associated with their process, and thus select one FIB or another. messages from the kernel would be associated with the fib they refer to and would only be received by a routing socket associated with that fib. (not yet implemented) In addition Netstat has been edited to be able to cope with the fact that the array is now 2 dimensional. (It looks in system memory using libkvm (!)). Old versions of netstat see only the first FIB. In addition two sysctls are added to give: a) the number of FIBs compiled in (active) b) the default FIB of the calling process. Early testing experience: ------------------------- Basically our (IronPort's) appliance does this functionality already using ipfw fwd but that method has some drawbacks. For example, It can't fully simulate a routing table because it can't influence the socket's choice of local address when a connect() is done. Testing during the generating of these changes has been remarkably smooth so far. Multiple tables have co-existed with no notable side effects, and packets have been routes accordingly. ipfw has grown 2 new keywords: setfib N ip from anay to any count ip from any to any fib N In pf there seems to be a requirement to be able to give symbolic names to the fibs but I do not have that capacity. I am not sure if it is required. SCTP has interestingly enough built in support for this, called VRFs in Cisco parlance. it will be interesting to see how that handles it when it suddenly actually does something. Where to next: -------------------- After committing the ABI compatible version and MFCing it, I'd like to proceed in a forward direction in -current. this will result in some roto-tilling in the routing code. Firstly: the current code's idea of having a separate tree per protocol family, all of the same format, and pointed to by the 1 dimensional array is a bit silly. Especially when one considers that there is code that makes assumptions about every protocol having the same internal structures there. Some protocols don't WANT that sort of structure. (for example the whole idea of a netmask is foreign to appletalk). This needs to be made opaque to the external code. My suggested first change is to add routing method pointers to the 'domain' structure, along with information pointing the data. instead of having an array of pointers to uniform structures, there would be an array pointing to the 'domain' structures for each protocol address domain (protocol family), and the methods this reached would be called. The methods would have an argument that gives FIB number, but the protocol would be free to ignore it. When the ABI can be changed it raises the possibilty of the addition of a fib entry into the "struct route". Currently, the structure contains the sockaddr of the desination, and the resulting fib entry. To make this work fully, one could add a fib number so that given an address and a fib, one can find the third element, the fib entry. Interaction with the ARP layer/ LL layer would need to be revisited as well. Qing Li has been working on this already.

Switch the entire IPv4 stack to keep the IP packet header in network byte order. Any host byte order processing is done in local variables and host byte order values are never[1] written to a packet. After this change a packet processed by the stack isn't modified at all[2] except for TTL. After this change a network stack hacker doesn't need to scratch his head trying to figure out what is the byte order at the given place in the stack. [1] One exception still remains. The raw sockets convert host byte order before pass a packet to an application. Probably this would remain for ages for compatibility. [2] The ip_input() still subtructs header len from ip->ip_len, but this is planned to be fixed soon.

Add code to allow the system to handle multiple routing tables. This particular implementation is designed to be fully backwards compatible and to be MFC-able to 7.x (and 6.x) Currently the only protocol that can make use of the multiple tables is IPv4 Similar functionality exists in OpenBSD and Linux. From my notes: ----- One thing where FreeBSD has been falling behind, and which by chance I have some time to work on is "policy based routing", which allows different packet streams to be routed by more than just the destination address. Constraints: ------------ I want to make some form of this available in the 6.x tree (and by extension 7.x) , but FreeBSD in general needs it so I might as well do it in -current and back port the portions I need. One of the ways that this can be done is to have the ability to instantiate multiple kernel routing tables (which I will now refer to as "Forwarding Information Bases" or "FIBs" for political correctness reasons). Which FIB a particular packet uses to make the next hop decision can be decided by a number of mechanisms. The policies these mechanisms implement are the "Policies" referred to in "Policy based routing". One of the constraints I have if I try to back port this work to 6.x is that it must be implemented as a EXTENSION to the existing ABIs in 6.x so that third party applications do not need to be recompiled in timespan of the branch. This first version will not have some of the bells and whistles that will come with later versions. It will, for example, be limited to 16 tables in the first commit. Implementation method, Compatible version. (part 1) ------------------------------- For this reason I have implemented a "sufficient subset" of a multiple routing table solution in Perforce, and back-ported it to 6.x. (also in Perforce though not always caught up with what I have done in -current/P4). The subset allows a number of FIBs to be defined at compile time (8 is sufficient for my purposes in 6.x) and implements the changes needed to allow IPV4 to use them. I have not done the changes for ipv6 simply because I do not need it, and I do not have enough knowledge of ipv6 (e.g. neighbor discovery) needed to do it. Other protocol families are left untouched and should there be users with proprietary protocol families, they should continue to work and be oblivious to the existence of the extra FIBs. To understand how this is done, one must know that the current FIB code starts everything off with a single dimensional array of pointers to FIB head structures (One per protocol family), each of which in turn points to the trie of routes available to that family. The basic change in the ABI compatible version of the change is to extent that array to be a 2 dimensional array, so that instead of protocol family X looking at rt_tables[X] for the table it needs, it looks at rt_tables[Y][X] when for all protocol families except ipv4 Y is always 0. Code that is unaware of the change always just sees the first row of the table, which of course looks just like the one dimensional array that existed before. The entry points rtrequest(), rtalloc(), rtalloc1(), rtalloc_ign() are all maintained, but refer only to the first row of the array, so that existing callers in proprietary protocols can continue to do the "right thing". Some new entry points are added, for the exclusive use of ipv4 code called in_rtrequest(), in_rtalloc(), in_rtalloc1() and in_rtalloc_ign(), which have an extra argument which refers the code to the correct row. In addition, there are some new entry points (currently called rtalloc_fib() and friends) that check the Address family being looked up and call either rtalloc() (and friends) if the protocol is not IPv4 forcing the action to row 0 or to the appropriate row if it IS IPv4 (and that info is available). These are for calling from code that is not specific to any particular protocol. The way these are implemented would change in the non ABI preserving code to be added later. One feature of the first version of the code is that for ipv4, the interface routes show up automatically on all the FIBs, so that no matter what FIB you select you always have the basic direct attached hosts available to you. (rtinit() does this automatically). You CAN delete an interface route from one FIB should you want to but by default it's there. ARP information is also available in each FIB. It's assumed that the same machine would have the same MAC address, regardless of which FIB you are using to get to it. This brings us as to how the correct FIB is selected for an outgoing IPV4 packet. Firstly, all packets have a FIB associated with them. if nothing has been done to change it, it will be FIB 0. The FIB is changed in the following ways. Packets fall into one of a number of classes. 1/ locally generated packets, coming from a socket/PCB. Such packets select a FIB from a number associated with the socket/PCB. This in turn is inherited from the process, but can be changed by a socket option. The process in turn inherits it on fork. I have written a utility call setfib that acts a bit like nice.. setfib -3 ping target.example.com # will use fib 3 for ping. It is an obvious extension to make it a property of a jail but I have not done so. It can be achieved by combining the setfib and jail commands. 2/ packets received on an interface for forwarding. By default these packets would use table 0, (or possibly a number settable in a sysctl(not yet)). but prior to routing the firewall can inspect them (see below). (possibly in the future you may be able to associate a FIB with packets received on an interface.. An ifconfig arg, but not yet.) 3/ packets inspected by a packet classifier, which can arbitrarily associate a fib with it on a packet by packet basis. A fib assigned to a packet by a packet classifier (such as ipfw) would over-ride a fib associated by a more default source. (such as cases 1 or 2). 4/ a tcp listen socket associated with a fib will generate accept sockets that are associated with that same fib. 5/ Packets generated in response to some other packet (e.g. reset or icmp packets). These should use the FIB associated with the packet being reponded to. 6/ Packets generated during encapsulation. gif, tun and other tunnel interfaces will encapsulate using the FIB that was in effect withthe proces that set up the tunnel. thus setfib 1 ifconfig gif0 [tunnel instructions] will set the fib for the tunnel to use to be fib 1. Routing messages would be associated with their process, and thus select one FIB or another. messages from the kernel would be associated with the fib they refer to and would only be received by a routing socket associated with that fib. (not yet implemented) In addition Netstat has been edited to be able to cope with the fact that the array is now 2 dimensional. (It looks in system memory using libkvm (!)). Old versions of netstat see only the first FIB. In addition two sysctls are added to give: a) the number of FIBs compiled in (active) b) the default FIB of the calling process. Early testing experience: ------------------------- Basically our (IronPort's) appliance does this functionality already using ipfw fwd but that method has some drawbacks. For example, It can't fully simulate a routing table because it can't influence the socket's choice of local address when a connect() is done. Testing during the generating of these changes has been remarkably smooth so far. Multiple tables have co-existed with no notable side effects, and packets have been routes accordingly. ipfw has grown 2 new keywords: setfib N ip from anay to any count ip from any to any fib N In pf there seems to be a requirement to be able to give symbolic names to the fibs but I do not have that capacity. I am not sure if it is required. SCTP has interestingly enough built in support for this, called VRFs in Cisco parlance. it will be interesting to see how that handles it when it suddenly actually does something. Where to next: -------------------- After committing the ABI compatible version and MFCing it, I'd like to proceed in a forward direction in -current. this will result in some roto-tilling in the routing code. Firstly: the current code's idea of having a separate tree per protocol family, all of the same format, and pointed to by the 1 dimensional array is a bit silly. Especially when one considers that there is code that makes assumptions about every protocol having the same internal structures there. Some protocols don't WANT that sort of structure. (for example the whole idea of a netmask is foreign to appletalk). This needs to be made opaque to the external code. My suggested first change is to add routing method pointers to the 'domain' structure, along with information pointing the data. instead of having an array of pointers to uniform structures, there would be an array pointing to the 'domain' structures for each protocol address domain (protocol family), and the methods this reached would be called. The methods would have an argument that gives FIB number, but the protocol would be free to ignore it. When the ABI can be changed it raises the possibilty of the addition of a fib entry into the "struct route". Currently, the structure contains the sockaddr of the desination, and the resulting fib entry. To make this work fully, one could add a fib number so that given an address and a fib, one can find the third element, the fib entry. Interaction with the ARP layer/ LL layer would need to be revisited as well. Qing Li has been working on this already.

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame. To avoid growing stack frame, we utilize LSB from the rule pointer, relying on kernel malloc(9) returning pointer aligned addresses. Discussed with: dhartmei

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

inp = in_pcblookup_mbuf(pi, saddr->v4, sport,
Decompose the current single inpcbinfo lock into two locks: - The existing ipi_lock continues to protect the global inpcb list and inpcb counter. This lock is now relegated to a small number of allocation and free operations, and occasional operations that walk all connections (including, awkwardly, certain UDP multicast receive operations -- something to revisit). - A new ipi_hash_lock protects the two inpcbinfo hash tables for looking up connections and bound sockets, manipulated using new INP_HASH_*() macros. This lock, combined with inpcb locks, protects the 4-tuple address space. Unlike the current ipi_lock, ipi_hash_lock follows the individual inpcb connection locks, so may be acquired while manipulating a connection on which a lock is already held, avoiding the need to acquire the inpcbinfo lock preemptively when a binding change might later be required. As a result, however, lookup operations necessarily go through a reference acquire while holding the lookup lock, later acquiring an inpcb lock -- if required. A new function in_pcblookup() looks up connections, and accepts flags indicating how to return the inpcb. Due to lock order changes, callers no longer need acquire locks before performing a lookup: the lookup routine will acquire the ipi_hash_lock as needed. In the future, it will also be able to use alternative lookup and locking strategies transparently to callers, such as pcbgroup lookup. New lookup flags are, supplementing the existing INPLOOKUP_WILDCARD flag: INPLOOKUP_RLOCKPCB - Acquire a read lock on the returned inpcb INPLOOKUP_WLOCKPCB - Acquire a write lock on the returned inpcb Callers must pass exactly one of these flags (for the time being). Some notes: - All protocols are updated to work within the new regime; especially, TCP, UDPv4, and UDPv6. pcbinfo ipi_lock acquisitions are largely eliminated, and global hash lock hold times are dramatically reduced compared to previous locking. - The TCP syncache still relies on the pcbinfo lock, something that we may want to revisit. - Support for reverting to the FreeBSD 7.x locking strategy in TCP input is no longer available -- hash lookup locks are now held only very briefly during inpcb lookup, rather than for potentially extended periods. However, the pcbinfo ipi_lock will still be acquired if a connection state might change such that a connection is added or removed. - Raw IP sockets continue to use the pcbinfo ipi_lock for protection, due to maintaining their own hash tables. - The interface in6_pcblookup_hash_locked() is maintained, which allows callers to acquire hash locks and perform one or more lookups atomically with 4-tuple allocation: this is required only for TCPv6, as there is no in6_pcbconnect_setup(), which there should be. - UDPv6 locking remains significantly more conservative than UDPv4 locking, which relates to source address selection. This needs attention, as it likely significantly reduces parallelism in this code for multithreaded socket use (such as in BIND). - In the UDPv4 and UDPv6 multicast cases, we need to revisit locking somewhat, as they relied on ipi_lock to stablise 4-tuple matches, which is no longer sufficient. A second check once the inpcb lock is held should do the trick, keeping the general case from requiring the inpcb lock for every inpcb visited. - This work reminds us that we need to revisit locking of the v4/v6 flags, which may be accessed lock-free both before and after this change. - Right now, a single lock name is used for the pcbhash lock -- this is undesirable, and probably another argument is required to take care of this (or a char array name field in the pcbinfo?). This is not an MFC candidate for 8.x due to its impact on lookup and locking semantics. It's possible some of these issues could be worked around with compatibility wrappers, if necessary.

inp = in6_pcblookup_mbuf(pi, &saddr->v6, sport,
Decompose the current single inpcbinfo lock into two locks: - The existing ipi_lock continues to protect the global inpcb list and inpcb counter. This lock is now relegated to a small number of allocation and free operations, and occasional operations that walk all connections (including, awkwardly, certain UDP multicast receive operations -- something to revisit). - A new ipi_hash_lock protects the two inpcbinfo hash tables for looking up connections and bound sockets, manipulated using new INP_HASH_*() macros. This lock, combined with inpcb locks, protects the 4-tuple address space. Unlike the current ipi_lock, ipi_hash_lock follows the individual inpcb connection locks, so may be acquired while manipulating a connection on which a lock is already held, avoiding the need to acquire the inpcbinfo lock preemptively when a binding change might later be required. As a result, however, lookup operations necessarily go through a reference acquire while holding the lookup lock, later acquiring an inpcb lock -- if required. A new function in_pcblookup() looks up connections, and accepts flags indicating how to return the inpcb. Due to lock order changes, callers no longer need acquire locks before performing a lookup: the lookup routine will acquire the ipi_hash_lock as needed. In the future, it will also be able to use alternative lookup and locking strategies transparently to callers, such as pcbgroup lookup. New lookup flags are, supplementing the existing INPLOOKUP_WILDCARD flag: INPLOOKUP_RLOCKPCB - Acquire a read lock on the returned inpcb INPLOOKUP_WLOCKPCB - Acquire a write lock on the returned inpcb Callers must pass exactly one of these flags (for the time being). Some notes: - All protocols are updated to work within the new regime; especially, TCP, UDPv4, and UDPv6. pcbinfo ipi_lock acquisitions are largely eliminated, and global hash lock hold times are dramatically reduced compared to previous locking. - The TCP syncache still relies on the pcbinfo lock, something that we may want to revisit. - Support for reverting to the FreeBSD 7.x locking strategy in TCP input is no longer available -- hash lookup locks are now held only very briefly during inpcb lookup, rather than for potentially extended periods. However, the pcbinfo ipi_lock will still be acquired if a connection state might change such that a connection is added or removed. - Raw IP sockets continue to use the pcbinfo ipi_lock for protection, due to maintaining their own hash tables. - The interface in6_pcblookup_hash_locked() is maintained, which allows callers to acquire hash locks and perform one or more lookups atomically with 4-tuple allocation: this is required only for TCPv6, as there is no in6_pcbconnect_setup(), which there should be. - UDPv6 locking remains significantly more conservative than UDPv4 locking, which relates to source address selection. This needs attention, as it likely significantly reduces parallelism in this code for multithreaded socket use (such as in BIND). - In the UDPv4 and UDPv6 multicast cases, we need to revisit locking somewhat, as they relied on ipi_lock to stablise 4-tuple matches, which is no longer sufficient. A second check once the inpcb lock is held should do the trick, keeping the general case from requiring the inpcb lock for every inpcb visited. - This work reminds us that we need to revisit locking of the v4/v6 flags, which may be accessed lock-free both before and after this change. - Right now, a single lock name is used for the pcbhash lock -- this is undesirable, and probably another argument is required to take care of this (or a char array name field in the pcbinfo?). This is not an MFC candidate for 8.x due to its impact on lookup and locking semantics. It's possible some of these issues could be worked around with compatibility wrappers, if necessary.

Decompose the current single inpcbinfo lock into two locks: - The existing ipi_lock continues to protect the global inpcb list and inpcb counter. This lock is now relegated to a small number of allocation and free operations, and occasional operations that walk all connections (including, awkwardly, certain UDP multicast receive operations -- something to revisit). - A new ipi_hash_lock protects the two inpcbinfo hash tables for looking up connections and bound sockets, manipulated using new INP_HASH_*() macros. This lock, combined with inpcb locks, protects the 4-tuple address space. Unlike the current ipi_lock, ipi_hash_lock follows the individual inpcb connection locks, so may be acquired while manipulating a connection on which a lock is already held, avoiding the need to acquire the inpcbinfo lock preemptively when a binding change might later be required. As a result, however, lookup operations necessarily go through a reference acquire while holding the lookup lock, later acquiring an inpcb lock -- if required. A new function in_pcblookup() looks up connections, and accepts flags indicating how to return the inpcb. Due to lock order changes, callers no longer need acquire locks before performing a lookup: the lookup routine will acquire the ipi_hash_lock as needed. In the future, it will also be able to use alternative lookup and locking strategies transparently to callers, such as pcbgroup lookup. New lookup flags are, supplementing the existing INPLOOKUP_WILDCARD flag: INPLOOKUP_RLOCKPCB - Acquire a read lock on the returned inpcb INPLOOKUP_WLOCKPCB - Acquire a write lock on the returned inpcb Callers must pass exactly one of these flags (for the time being). Some notes: - All protocols are updated to work within the new regime; especially, TCP, UDPv4, and UDPv6. pcbinfo ipi_lock acquisitions are largely eliminated, and global hash lock hold times are dramatically reduced compared to previous locking. - The TCP syncache still relies on the pcbinfo lock, something that we may want to revisit. - Support for reverting to the FreeBSD 7.x locking strategy in TCP input is no longer available -- hash lookup locks are now held only very briefly during inpcb lookup, rather than for potentially extended periods. However, the pcbinfo ipi_lock will still be acquired if a connection state might change such that a connection is added or removed. - Raw IP sockets continue to use the pcbinfo ipi_lock for protection, due to maintaining their own hash tables. - The interface in6_pcblookup_hash_locked() is maintained, which allows callers to acquire hash locks and perform one or more lookups atomically with 4-tuple allocation: this is required only for TCPv6, as there is no in6_pcbconnect_setup(), which there should be. - UDPv6 locking remains significantly more conservative than UDPv4 locking, which relates to source address selection. This needs attention, as it likely significantly reduces parallelism in this code for multithreaded socket use (such as in BIND). - In the UDPv4 and UDPv6 multicast cases, we need to revisit locking somewhat, as they relied on ipi_lock to stablise 4-tuple matches, which is no longer sufficient. A second check once the inpcb lock is held should do the trick, keeping the general case from requiring the inpcb lock for every inpcb visited. - This work reminds us that we need to revisit locking of the v4/v6 flags, which may be accessed lock-free both before and after this change. - Right now, a single lock name is used for the pcbhash lock -- this is undesirable, and probably another argument is required to take care of this (or a char array name field in the pcbinfo?). This is not an MFC candidate for 8.x due to its impact on lookup and locking semantics. It's possible some of these issues could be worked around with compatibility wrappers, if necessary.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame. To avoid growing stack frame, we utilize LSB from the rule pointer, relying on kernel malloc(9) returning pointer aligned addresses. Discussed with: dhartmei

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame. To avoid growing stack frame, we utilize LSB from the rule pointer, relying on kernel malloc(9) returning pointer aligned addresses. Discussed with: dhartmei

Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame. To avoid growing stack frame, we utilize LSB from the rule pointer, relying on kernel malloc(9) returning pointer aligned addresses. Discussed with: dhartmei

Once pf became not covered by a single mutex, many counters in it became race prone. Some just gather statistics, but some are later used in different calculations. A real problem was the race provoked underflow of the states_cur counter on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this value is used in pf_state_expires() and any state created by this rule is immediately expired. Thus, make fields states_cur, states_tot and src_nodes of struct pf_rule be counter(9)s. Thanks to Dennis for providing me shell access to problematic box and his help with reproducing, debugging and investigating the problem.

Extend IPv6 routing lookups in pf(4) to use the new multi-FIB KPI. Try to make the "rtable" handling work but the current version of pf(4) does not fully support it yet as especially callers of PF_MISMATCHAW() are not fully FIB-aware. OpenBSD seems to have fixed this in a later version. Prepare as much as possible. Sponsored by: Cisco Systems, Inc.

Make ruleset anchors in pf(4) reentrant. We've got two problems here: 1) Ruleset parser uses a global variable for anchor stack. 2) When processing a wildcard anchor, matching anchors are marked. To fix the first one: o Allocate anchor processing stack on stack. To make this allocation as small as possible, following measures taken: - Maximum stack size reduced from 64 to 32. - The struct pf_anchor_stackframe trimmed by one pointer - parent. We can always obtain the parent via the rule pointer. - When pf_test_rule() calls pf_get_translation(), the former lends its stack to the latter, to avoid recursive allocation 32 entries. The second one appeared more tricky. The code, that marks anchors was added in OpenBSD rev. 1.516 of pf.c. According to commit log, the idea is to enable the "quick" keyword on an anchor rule. The feature isn't documented anywhere. The most obscure part of the 1.516 was that code examines the "match" mark on a just processed child, which couldn't be put here by current frame. Since this wasn't documented even in the commit message and functionality of this is not clear to me, I decided to drop this examination for now. The rest of 1.516 is redone in a thread safe manner - the mark isn't put on the anchor itself, but on current stack frame. To avoid growing stack frame, we utilize LSB from the rule pointer, relying on kernel malloc(9) returning pointer aligned addresses. Discussed with: dhartmei

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

* 3) Packets get funky immediately after the connection
* closes (this should catch Solaris spurious ACK|FINs
* that web servers like to spew after a close)
*
* This must be a little more careful than the above code
* since packet floods will also be caught here. We don't
* update the TTL here to mitigate the damage of a packet
* flood and so the same code can handle awkward establishment
* and a loosened connection close.
* In the establishment case, a correct peer response will
* validate the connection, go through the normal state code
* and keep updating the state TTL.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

When checking the sequence number of a TCP header embedded in an ICMP error message, do not access th_flags. The field is beyond the first eight bytes of the header that are required to be present and were pulled up in the mbuf. A random value of th_flags can have TH_SYN set, which made the sequence number comparison not apply the window scaling factor, which led to legitimate ICMP(v6) packets getting blocked with "BAD ICMP" debug log messages (if enabled with pfctl -xm), thus breaking PMTU discovery. Triggering the bug requires TCP window scaling to be enabled (sysctl net.inet.tcp.rfc1323, enabled by default) on both end- points of the TCP connection. Large scaling factors increase the probability of triggering the bug. PR: kern/115413: [ipv6] ipv6 pmtu not working Tested by: Jacek Zapala Reviewed by: mlaier Approved by: re (kensmith)

Adapt OpenBSD pf's "sloopy" TCP state machine which is useful for Direct Server Return mode, where not all packets would be visible to the load balancer or gateway. This commit should be reverted when we merge future pf versions. The benefit it would provide is that this version does not break any existing public interface and thus won't be a problem if we want to MFC it to earlier FreeBSD releases.

Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Commit pf version 3.5 and link additional files to the kernel build. Version 3.5 brings: - Atomic commits of ruleset changes (reduce the chance of ending up in an inconsistent state). - A 30% reduction in the size of state table entries. - Source-tracking (limit number of clients and states per client). - Sticky-address (the flexibility of round-robin with the benefits of source-hash). - Significant improvements to interface handling. - and many more ...

Extend IPv6 routing lookups in pf(4) to use the new multi-FIB KPI. Try to make the "rtable" handling work but the current version of pf(4) does not fully support it yet as especially callers of PF_MISMATCHAW() are not fully FIB-aware. OpenBSD seems to have fixed this in a later version. Prepare as much as possible. Sponsored by: Cisco Systems, Inc.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Commit pf version 3.5 and link additional files to the kernel build. Version 3.5 brings: - Atomic commits of ruleset changes (reduce the chance of ending up in an inconsistent state). - A 30% reduction in the size of state table entries. - Source-tracking (limit number of clients and states per client). - Sticky-address (the flexibility of round-robin with the benefits of source-hash). - Significant improvements to interface handling. - and many more ...

o Remove last argument to ip_fragment(), and obtain all needed information on checksums directly from mbuf flags. This simplifies code. o Clear CSUM_IP from the mbuf in ip_fragment() if we did checksums in hardware. Some driver may not announce CSUM_IP in theur if_hwassist, although try to do checksums if CSUM_IP set on mbuf. Example is em(4). o While here, consistently use CSUM_IP instead of its alias CSUM_DELAY_IP. After this change CSUM_DELAY_IP vanishes from the stack.

Many network stack subsystems use a single global data structure to hold all pertinent statatistics for the subsystem. These structures are sometimes "borrowed" by kernel modules that require a place to store statistics for similar events. Add KPI accessor functions for statistics structures referenced by kernel modules so that they no longer encode certain specifics of how the data structures are named and stored. This change is intended to make it easier to move to per-CPU network stats following 8.0-RELEASE. The following modules are affected by this change: if_bridge if_cxgb if_gif ip_mroute ipdivert pf In practice, most of these statistics consumers should, in fact, maintain their own statistics data structures rather than borrowing structures from the base network stack. However, that change is too agressive for this point in the release cycle. Reviewed by: bz Approved by: re (kib)

After r241245 it appeared that in_delayed_cksum(), which still expects host byte order, was sometimes called with net byte order. Since we are moving towards net byte order throughout the stack, the function was converted to expect net byte order, and its consumers fixed appropriately: - ip_output(), ipfilter(4) not changed, since already call in_delayed_cksum() with header in net byte order. - divert(4), ng_nat(4), ipfw_nat(4) now don't need to swap byte order there and back. - mrouting code and IPv6 ipsec now need to switch byte order there and back, but I hope, this is temporary solution. - In ipsec(4) shifted switch to net byte order prior to in_delayed_cksum(). - pf_route() catches up on r241245 changes to ip_output().

/* Copied from FreeBSD 10.0-CURRENT ip_output. */
Bring diff from the security/pf port. This has code been tested as a port for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)

o Remove last argument to ip_fragment(), and obtain all needed information on checksums directly from mbuf flags. This simplifies code. o Clear CSUM_IP from the mbuf in ip_fragment() if we did checksums in hardware. Some driver may not announce CSUM_IP in theur if_hwassist, although try to do checksums if CSUM_IP set on mbuf. Example is em(4). o While here, consistently use CSUM_IP instead of its alias CSUM_DELAY_IP. After this change CSUM_DELAY_IP vanishes from the stack.

Some driver may not announce CSUM_IP in theur if_hwassist, although try to do checksums if CSUM_IP set on mbuf.

After r241245 it appeared that in_delayed_cksum(), which still expects host byte order, was sometimes called with net byte order. Since we are moving towards net byte order throughout the stack, the function was converted to expect net byte order, and its consumers fixed appropriately: - ip_output(), ipfilter(4) not changed, since already call in_delayed_cksum() with header in net byte order. - divert(4), ng_nat(4), ipfw_nat(4) now don't need to swap byte order there and back. - mrouting code and IPv6 ipsec now need to switch byte order there and back, but I hope, this is temporary solution. - In ipsec(4) shifted switch to net byte order prior to in_delayed_cksum(). - pf_route() catches up on r241245 changes to ip_output().

After r241245 it appeared that in_delayed_cksum(), which still expects host byte order, was sometimes called with net byte order. Since we are moving towards net byte order throughout the stack, the function was converted to expect net byte order, and its consumers fixed appropriately: - ip_output(), ipfilter(4) not changed, since already call in_delayed_cksum() with header in net byte order. - divert(4), ng_nat(4), ipfw_nat(4) now don't need to swap byte order there and back. - mrouting code and IPv6 ipsec now need to switch byte order there and back, but I hope, this is temporary solution. - In ipsec(4) shifted switch to net byte order prior to in_delayed_cksum(). - pf_route() catches up on r241245 changes to ip_output().

Many network stack subsystems use a single global data structure to hold all pertinent statatistics for the subsystem. These structures are sometimes "borrowed" by kernel modules that require a place to store statistics for similar events. Add KPI accessor functions for statistics structures referenced by kernel modules so that they no longer encode certain specifics of how the data structures are named and stored. This change is intended to make it easier to move to per-CPU network stats following 8.0-RELEASE. The following modules are affected by this change: if_bridge if_cxgb if_gif ip_mroute ipdivert pf In practice, most of these statistics consumers should, in fact, maintain their own statistics data structures rather than borrowing structures from the base network stack. However, that change is too agressive for this point in the release cycle. Reviewed by: bz Approved by: re (kib)

Many network stack subsystems use a single global data structure to hold all pertinent statatistics for the subsystem. These structures are sometimes "borrowed" by kernel modules that require a place to store statistics for similar events. Add KPI accessor functions for statistics structures referenced by kernel modules so that they no longer encode certain specifics of how the data structures are named and stored. This change is intended to make it easier to move to per-CPU network stats following 8.0-RELEASE. The following modules are affected by this change: if_bridge if_cxgb if_gif ip_mroute ipdivert pf In practice, most of these statistics consumers should, in fact, maintain their own statistics data structures rather than borrowing structures from the base network stack. However, that change is too agressive for this point in the release cycle. Reviewed by: bz Approved by: re (kib)

Define semantic of M_SKIP_FIREWALL more precisely, i.e. also pass associated icmp_error() packets. While here retire PACKET_TAG_PF_GENERATED (which served the same purpose) and use M_SKIP_FIREWALL in pf as well. This should speed up things a bit as we get rid of the tag allocations.

Many network stack subsystems use a single global data structure to hold all pertinent statatistics for the subsystem. These structures are sometimes "borrowed" by kernel modules that require a place to store statistics for similar events. Add KPI accessor functions for statistics structures referenced by kernel modules so that they no longer encode certain specifics of how the data structures are named and stored. This change is intended to make it easier to move to per-CPU network stats following 8.0-RELEASE. The following modules are affected by this change: if_bridge if_cxgb if_gif ip_mroute ipdivert pf In practice, most of these statistics consumers should, in fact, maintain their own statistics data structures rather than borrowing structures from the base network stack. However, that change is too agressive for this point in the release cycle. Reviewed by: bz Approved by: re (kib)

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Adapt OpenBSD pf's "sloopy" TCP state machine which is useful for Direct Server Return mode, where not all packets would be visible to the load balancer or gateway. This commit should be reverted when we merge future pf versions. The benefit it would provide is that this version does not break any existing public interface and thus won't be a problem if we want to MFC it to earlier FreeBSD releases.

Commit pf version 3.5 and link additional files to the kernel build. Version 3.5 brings: - Atomic commits of ruleset changes (reduce the chance of ending up in an inconsistent state). - A 30% reduction in the size of state table entries. - Source-tracking (limit number of clients and states per client). - Sticky-address (the flexibility of round-robin with the benefits of source-hash). - Significant improvements to interface handling. - and many more ...

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.

Also: - Handle ICMP6 messages which are typically sent to multicast addresses but recieve unicast replies, by doing fallthrough lookups against the correct multicast address. - Clear up some mistaken assumptions in the PF code: - Not all ICMP packets have an icmp_id, so simulate one based on other data if we can, otherwise set it to 0. - Don't modify the icmp id field in NAT unless it's echo - Use the full range of possible id's when NATing icmp6 echoy Difference with OpenBSD version: - C99ify the new code - WITHOUT_INET6 safe Reviewed by: glebius Obtained from: OpenBSD

Adapt OpenBSD pf's "sloopy" TCP state machine which is useful for Direct Server Return mode, where not all packets would be visible to the load balancer or gateway. This commit should be reverted when we merge future pf versions. The benefit it would provide is that this version does not break any existing public interface and thus won't be a problem if we want to MFC it to earlier FreeBSD releases.

And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212.
