sys: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Ok, here it is, we finally add SCTP to current. Note that this work is not just mine, but it is also the works of Peter Lei and Michael Tuexen. They both are my two key other developers working on the project.. and they need ata-boy's too: **** peterlei@cisco.com tuexen@fh-muenster.de **** I did do a make sysent which updated the syscall's and sysproto.. I hope that is correct... without it you don't build since we have new syscalls for SCTP :-0 So go out and look at the NOTES, add option SCTP (make sure inet and inet6 are present too) and play with SCTP. I will see about comitting some test tools I have after I figure out where I should place them. I also have a lib (libsctp.a) that adds some of the missing socketapi functions that I need to put into lib's.. I will talk to George about this :-) There may still be some 64 bit issues in here, none of us have a 64 bit processor to test with yet.. Michael may have a MAC but thats another beast too..

#include "opt_sctp.h"
This patch provides the back end support for equal-cost multi-path (ECMP) for both IPv4 and IPv6. Previously, multipath route insertion is disallowed. For example, route add -net 192.103.54.0/24 10.9.44.1 route add -net 192.103.54.0/24 10.9.44.2 The second route insertion will trigger an error message of "add net 192.103.54.0/24: gateway 10.2.5.2: route already in table" Multiple default routes can also be inserted. Here is the netstat output: default 10.2.5.1 UGS 0 3074 bge0 => default 10.2.5.2 UGS 0 0 bge0 When multipath routes exist, the "route delete" command requires a specific gateway to be specified or else an error message would be displayed. For example, route delete default would fail and trigger the following error message: "route: writing to routing socket: No such process" "delete net default: not in table" On the other hand, route delete default 10.2.5.2 would be successful: "delete net default: gateway 10.2.5.2" One does not have to specify a gateway if there is only a single route for a particular destination. I need to perform more testings on address aliases and multiple interfaces that have the same IP prefixes. This patch as it stands today is not yet ready for prime time. Therefore, the ECMP code fragments are fully guarded by the RADIX_MPATH macro. Include the "options RADIX_MPATH" in the kernel configuration to enable this feature.

Conditionally compile out V_ globals while instantiating the appropriate container structures, depending on VIMAGE_GLOBALS compile time option. Make VIMAGE_GLOBALS a new compile-time option, which by default will not be defined, resulting in instatiations of global variables selected for V_irtualization (enclosed in #ifdef VIMAGE_GLOBALS blocks) to be effectively compiled out. Instantiate new global container structures to hold V_irtualized variables: vnet_net_0, vnet_inet_0, vnet_inet6_0, vnet_ipsec_0, vnet_netgraph_0, and vnet_gif_0. Update the VSYM() macro so that depending on VIMAGE_GLOBALS the V_ macros resolve either to the original globals, or to fields inside container structures, i.e. effectively #ifdef VIMAGE_GLOBALS #define V_rt_tables rt_tables #else #define V_rt_tables vnet_net_0._rt_tables #endif Update SYSCTL_V_*() macros to operate either on globals or on fields inside container structs. Extend the internal kldsym() lookups with the ability to resolve selected fields inside the virtualization container structs. This applies only to the fields which are explicitly registered for kldsym() visibility via VNET_MOD_DECLARE() and vnet_mod_register(), currently this is done only in sys/net/if.c. Fix a few broken instances of MODULE_GLOBAL() macro use in SCTP code, and modify the MODULE_GLOBAL() macro to resolve to V_ macros, which in turn result in proper code being generated depending on VIMAGE_GLOBALS. De-virtualize local static variables in sys/contrib/pf/net/pf_subr.c which were prematurely V_irtualized by automated V_ prepending scripts during earlier merging steps. PF virtualization will be done separately, most probably after next PF import. Convert a few variable initializations at instantiation to initialization in init functions, most notably in ipfw. Also convert TUNABLE_INT() initializers for V_ variables to TUNABLE_FETCH_INT() in initializer functions.

This main goals of this project are: 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code, The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries. Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently: - Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion

Initial get-the-easy-case-working upgrade of the multicast code to something more recent than the ancient 1.2 release contained in 4.4. This code has the following advantages as compared to previous versions (culled from the README file for the SunOS release): - True multicast delivery - Configurable rate-limiting of forwarded multicast traffic on each physical interface or tunnel, using a token-bucket limiter. - Simplistic classification of packets for prioritized dropping. - Administrative scoping of multicast address ranges. - Faster detection of hosts leaving groups. - Support for multicast traceroute (code not yet available). - Support for RSVP, the Resource Reservation Protocol. What still needs to be done: - The multicast forwarder needs testing. - The multicast routing daemon needs to be ported. - Network interface drivers need to have the `#ifdef MULTICAST' goop ripped out of them. - The IGMP code should probably be bogon-tested. Some notes about the porting process: In some cases, the Berkeley people decided to incorporate functionality from later releases of the multicast code, but then had to do things differently. As a result, if you look at Deering's patches, and then look at our code, it is not always obvious whether the patch even applies. Let the reader beware. I ran ip_mroute.c through several passes of `unifdef' to get rid of useless grot, and to permanently enable the RSVP support, which we will include as standard.

Ok, here it is, we finally add SCTP to current. Note that this work is not just mine, but it is also the works of Peter Lei and Michael Tuexen. They both are my two key other developers working on the project.. and they need ata-boy's too: **** peterlei@cisco.com tuexen@fh-muenster.de **** I did do a make sysent which updated the syscall's and sysproto.. I hope that is correct... without it you don't build since we have new syscalls for SCTP :-0 So go out and look at the NOTES, add option SCTP (make sure inet and inet6 are present too) and play with SCTP. I will see about comitting some test tools I have after I figure out where I should place them. I also have a lib (libsctp.a) that adds some of the missing socketapi functions that I need to put into lib's..

Remove IPsec related PCB code from SCTP. The inpcb structure has inp_sp pointer that is initialized by ipsec_init_pcbpolicy() function. This pointer keeps strorage for IPsec security policies associated with a specific socket. An application can use IP_IPSEC_POLICY and IPV6_IPSEC_POLICY socket options to configure these security policies. Then ip[6]_output() uses inpcb pointer to specify that an outgoing packet is associated with some socket. And IPSEC_OUTPUT() method can use a security policy stored in the inp_sp. For inbound packet the protocol-specific input routine uses IPSEC_CHECK_POLICY() method to check that a packet conforms to inbound security policy configured in the inpcb. SCTP protocol doesn't specify inpcb for ip[6]_output() when it sends packets. Thus IPSEC_OUTPUT() method does not consider such packets as associated with some socket and can not apply security policies from inpcb, even if they are configured. Since IPSEC_CHECK_POLICY() method is called from protocol-specific input routine, it can specify inpcb pointer and associated with socket inbound policy will be checked. But there are two problems: 1. Such check is asymmetric, becasue we can not apply security policy from inpcb for outgoing packet. 2. IPSEC_CHECK_POLICY() expects that caller holds INPCB lock and access to inp_sp is protected. But for SCTP this is not correct, becasue SCTP uses own locks to protect inpcb. To fix these problems remove IPsec related PCB code from SCTP. This imply that IP_IPSEC_POLICY and IPV6_IPSEC_POLICY socket options will be not applicable to SCTP sockets. To be able correctly check inbound security policies for SCTP, mark its protocol header with the PR_LASTHDR flag.

This patch provides the back end support for equal-cost multi-path (ECMP) for both IPv4 and IPv6. Previously, multipath route insertion is disallowed. For example, route add -net 192.103.54.0/24 10.9.44.1 route add -net 192.103.54.0/24 10.9.44.2 The second route insertion will trigger an error message of "add net 192.103.54.0/24: gateway 10.2.5.2: route already in table" Multiple default routes can also be inserted. Here is the netstat output: default 10.2.5.1 UGS 0 3074 bge0 => default 10.2.5.2 UGS 0 0 bge0 When multipath routes exist, the "route delete" command requires a specific gateway to be specified or else an error message would be displayed. For example, route delete default would fail and trigger the following error message: "route: writing to routing socket: No such process" "delete net default: not in table" On the other hand, route delete default 10.2.5.2 would be successful: "delete net default: gateway 10.2.5.2" One does not have to specify a gateway if there is only a single route for a particular destination. I need to perform more testings on address aliases and multiple interfaces that have the same IP prefixes. This patch as it stands today is not yet ready for prime time. Therefore, the ECMP code fragments are fully guarded by the RADIX_MPATH macro. Include the "options RADIX_MPATH" in the kernel configuration to enable this feature.

For example, route add -net 192.103.54.0/24 10.9.44.1 route add -net 192.103.54.0/24 10.9.44.2 The second route insertion will trigger an error message of "add net 192.103.54.0/24: gateway 10.2.5.2: route already in table" Multiple default routes can also be inserted. Here is the netstat output: default 10.2.5.1 UGS 0 3074 bge0 => default 10.2.5.2 UGS 0 0 bge0 When multipath routes exist, the "route delete" command requires a specific gateway to be specified or else an error message would be displayed. For example, route delete default would fail and trigger the following error message: "route: writing to routing socket: No such process" "delete net default: not in table" On the other hand, route delete default 10.2.5.2 would be successful: "delete net default: gateway 10.2.5.2" One does not have to specify a gateway if there is only a single route for a particular destination. I need to perform more testings on address aliases and multiple interfaces that have the same IP prefixes. This patch as it stands today is not yet ready for prime time. Therefore, the ECMP code fragments are fully guarded by the RADIX_MPATH macro. Include the "options RADIX_MPATH" in the kernel configuration to enable this feature.

This main goals of this project are: 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code, The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries. Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently: - Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion

Introduce and use a sysinit-based initialization scheme for virtual network stacks, VNET_SYSINIT: - Add VNET_SYSINIT and VNET_SYSUNINIT macros to declare events that will occur each time a network stack is instantiated and destroyed. In the !VIMAGE case, these are simply mapped into regular SYSINIT/SYSUNINIT. For the VIMAGE case, we instead use SYSINIT's to track their order and properties on registration, using them for each vnet when created/ destroyed, or immediately on module load for already-started vnets. - Remove vnet_modinfo mechanism that existed to serve this purpose previously, as well as its dependency scheme: we now just use the SYSINIT ordering scheme. - Implement VNET_DOMAIN_SET() to allow protocol domains to declare that they want init functions to be called for each virtual network stack rather than just once at boot, compiling down to DOMAIN_SET() in the non-VIMAGE case. - Walk all virtualized kernel subsystems and make use of these instead of modinfo or DOMAIN_SET() for init/uninit events. In some cases, convert modular components from using modevent to using sysinit (where appropriate). In some cases, do minor rejuggling of SYSINIT ordering to make room for or better manage events.

Make in_proto.c dependent on either inet or inet6. While it does not provide any functionality for IPv6, it provides the sysctl nodes for net.inet.* that a lot of functionality shared between IPv4 and IPv6 depends on. We cannot change these anymore without breaking a lot of management and tuning. In case of IPv6 only, we compile out everything but the sysctl node declarations.

Ok, here it is, we finally add SCTP to current. Note that this work is not just mine, but it is also the works of Peter Lei and Michael Tuexen. They both are my two key other developers working on the project.. and they need ata-boy's too: **** peterlei@cisco.com tuexen@fh-muenster.de **** I did do a make sysent which updated the syscall's and sysproto.. I hope that is correct... without it you don't build since we have new syscalls for SCTP :-0 So go out and look at the NOTES, add option SCTP (make sure inet and inet6 are present too) and play with SCTP. I will see about comitting some test tools I have after I figure out where I should place them. I also have a lib (libsctp.a) that adds some of the missing socketapi functions that I need to put into lib's.. I will talk to George about this :-) There may still be some 64 bit issues in here, none of us have a 64 bit processor to test with yet.. Michael may have a MAC but thats another beast too.. If you have a mac and want to use SCTP contact Michael he maintains a web site with a loadable module with this code :-) Reviewed by: gnn Approved by: gnn

Merge projects/ipsec into head/. Small summary ------------- o Almost all IPsec releated code was moved into sys/netipsec. o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel option IPSEC_SUPPORT added. It enables support for loading and unloading of ipsec.ko and tcpmd5.ko kernel modules. o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type support was removed. Added TCP/UDP checksum handling for inbound packets that were decapsulated by transport mode SAs. setkey(8) modified to show run-time NAT-T configuration of SA. o New network pseudo interface if_ipsec(4) added. For now it is build as part of ipsec.ko module (or with IPSEC kernel). It implements IPsec virtual tunnels to create route-based VPNs. o The network stack now invokes IPsec functions using special methods. The only one header file <netipsec/ipsec_support.h> should be included to declare all the needed things to work with IPsec. o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed. Now these protocols are handled directly via IPsec methods. o TCP_SIGNATURE support was reworked to be more close to RFC. o PF_KEY SADB was reworked: - now all security associations stored in the single SPI namespace, and all SAs MUST have unique SPI. - several hash tables added to speed up lookups in SADB. - SADB now uses rmlock to protect access, and concurrent threads can do SA lookups in the same time. - many PF_KEY message handlers were reworked to reflect changes in SADB. - SADB_UPDATE message was extended to support new PF_KEY headers: SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They can be used by IKE daemon to change SA addresses. o ipsecrequest and secpolicy structures were cardinally changed to avoid locking protection for ipsecrequest. Now we support only limited number (4) of bundled SAs, but they are supported for both INET and INET6. o INPCB security policy cache was introduced. Each PCB now caches used security policies to avoid SP lookup for each packet. o For inbound security policies added the mode, when the kernel does check for full history of applied IPsec transforms. o References counting rules for security policies and security associations were changed. The proper SA locking added into xform code. o xform code was also changed. Now it is possible to unregister xforms. tdb_xxx structures were changed and renamed to reflect changes in SADB/SPDB, and changed rules for locking and refcounting.

Convert raw IP from mondo-switch-statement-from-Hell to pr_usrreqs. Collapse duplicates with udp_usrreq.c and tcp_usrreq.c (calling the generic routines in uipc_socket2.c and in_pcb.c). Calling sockaddr()_ or peeraddr() on a detached socket now traps, rather than harmlessly returning an error; this should never happen. Allow the raw IP buffer sizes to be controlled via sysctl.

The accept filter code is not specific to the FreeBSD IPv4 network stack, so it really should not be under "optional inet". The fact that uipc_accf.c lives under kern/ lends some weight to making it a "standard" file. Moving kern/uipc_accf.c from "optional inet" to "standard" eliminates the need for #ifdef INET in kern/uipc_socket.c. Also, this meant the net.inet.accf.unloadable sysctl needed to move, as net.inet does not exist without networking compiled in (as it lives in netinet/in_proto.c.) The new sysctl has been named net.accf.unloadable. In order to support existing accept filter sysctls, the net.inet.accf node has been added netinet/in_proto.c.
