system primitives, and encourage loud failure through extra sanity
checking and fail stop semantics. They also substantially impact
system performance. If you want to do performance measurement,
benchmarking, and optimization, you'll want to turn them off. This
includes various WITNESS- related kernel options, INVARIANTS, malloc
debugging flags in userland, and various verbose features in the
kernel. Many developers choose to disable these features on build

2013-04-06 13:47:44 +00:00
20130404:
Legacy ATA stack, disabled and replaced by new CAM-based one since
FreeBSD 9.0, completely removed from the sources. Kernel modules
atadisk and atapi*, user-level tools atacontrol and burncd are
removed. Kernel option `options ATA_CAM` is now permanently enabled
and removed.
Add warning about SOCK_CLOEXEC and SOCK_NONBLOCK (r248534). Reviewed by: rpaulo
2013-04-06 22:28:19 +00:00
20130319:
SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2)
and socketpair(2). Software, in particular Kerberos, may
automatically detect and use these during building. The resulting
binaries will not work on older kernels.
Merge r247814 from x86 modulo whitespace bug: Turn on the CTL disable tunable by default. This will allow GENERIC configurations to boot on small memory boxes, but not require end users who want to use CTL to recompile their kernel. They can simply set kern.cam.ctl.disable=0 in loader.conf.
2013-03-08 13:11:45 +00:00
20130308:
CTL_DISABLE has also been added to the sparc64 GENERIC (for further
information, see the respective 20130304 entry).
Re-enable CTL in GENERIC on i386 and amd64, but turn on the CTL disable tunable by default. This will allow GENERIC configurations to boot on small memory boxes, but not require end users who want to use CTL to recompile their kernel. They can simply set kern.cam.ctl.disable=0 in loader.conf. The eventual solution to the memory usage problem is to change the way CTL allocates memory to be more configurable, but this should fix things for small memory situations in the mean time. UPDATING: Explain the change in the CTL configuration, and how users can enable CTL if they would like to use it. sys/conf/options: Add a new option, CTL_DISABLE, that prevents CTL from initializing. ctl.c: If CTL_DISABLE is turned on, don't initialize. i386/conf/GENERIC, amd64/conf/GENERIC: Re-enable device ctl, and add the CTL_DISABLE option.

- Bump __FreeBSD_version after recent callout(9) changes. - Add an entry in UPDATING to notice users about breakages.
2013-03-04 22:41:49 +00:00
Recent commits to callout(9) changed the size of struct callout,
so the KBI is probably heavily disturbed. Also, some functions
in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced
by macros. Every kernel module using it won't load, so rebuild
is requested.
Re-enable CTL in GENERIC on i386 and amd64, but turn on the CTL disable tunable by default. This will allow GENERIC configurations to boot on small memory boxes, but not require end users who want to use CTL to recompile their kernel.

2013-03-04 21:18:45 +00:00
The ctl device has been re-enabled in GENERIC for i386 and amd64,
but does not initialize by default (because of the new CTL_DISABLE
option) to save memory. To re-enable it, remove the CTL_DISABLE
option from the kernel config file or set kern.cam.ctl.disable=0
in /boot/loader.conf.
Disable the ctl driver in GENERIC. It unfortunately steals a fair chunk of RAM at startup even if it's not actively used, which prevents FreeBSD VMs of 128MB from successfully booting and running.
2013-03-02 08:12:41 +00:00
20130301:
The ctl device has been disabled in GENERIC for i386 and amd64.
This was done due to the extra memory being allocated at system
initialisation time by the ctl driver which was only used if
a CAM target device was created. This makes a FreeBSD system
unusable on 128MB or less of RAM.

20121117:
The sin6_scope_id member variable in struct sockaddr_in6 is now

20121023:
The ZERO_COPY_SOCKET kernel option has been removed and
split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP.
NB: SOCKET_SEND_COW uses the VM page based copy-on-write
mechanism which is not safe and may result in kernel crashes.
NB: The SOCKET_RECV_PFLIP mechanism is useless as no current
driver supports disposeable external page sized mbuf storage.
Proper replacements for both zero-copy mechanisms are under
consideration and will eventually lead to complete removal
of the two kernel options.
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.

The operations are necessary to implement proper unix socket handling on layered file systems like nullfs(5). This change fixes the long standing issue with nullfs(5) being in that unix sockets did not work between lower and upper layers: if we bound to a socket on the lower layer we could connect only to the lower path; if we bound to the upper layer we could connect only to the upper path.

A major overhaul of the CARP implementation. The ip_carp.c was started from scratch, copying needed functionality from the old implemenation on demand, with a thorough review of all code. The main change is that interface layer has been removed from the CARP. Now redundant addresses are configured exactly on the interfaces, they run on. The CARP configuration itself is, as before, configured and read via SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or SIOCAIFADDR_IN6 may now be configured to a particular virtual host id, which makes the prefix redundant. ifconfig(8) semantics has been changed too: now one doesn't need to clone carpXX interface, he/she should directly configure a vhid on a Ethernet interface. To supply vhid data from the kernel to an application the getifaddrs(8) function had been changed to pass ifam_data with each address. [1] The new implementation definitely closes all PRs related to carp(4) being an interface, and may close several others. It also allows to run a single redundant IP per interface. Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for idea on using ifam_data and for several rounds of reviewing!

The first time a system is booted after this change, the

main effect of this is a change to the NFS server file handles
for file systems that use vfc_typenum in their fsid, such as ZFS.
It will, however, prevent vfc_typenum from changing when file
systems are loaded in a different order for subsequent reboots.
To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf
until you are ready to remount all NFS clients after a reboot.

We still provide a way to disable individual CPUs or all hyperthreading "twin" CPUs before SMP startup. See the UPDATING entry for details. Interaction between building CPU topology and disabling CPUs still remains fuzzy: topology is first built using all availble CPUs and then the disabled CPUs should be "subtracted" from it.

Although mounts via fstype "nfs" will usually work without userland

mount_oldnfs be created. The new client is compiled into the
kernel with "options NFSCL" and this is needed for diskless root
file systems. The GENERIC kernel configs have been changed to use
NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER.
To use the regular/old client, you can "mount -t oldnfs ...". For
a diskless root file system, you must also include a line like:
vfs.root.mountfrom="oldnfs:"
in the boot/loader.conf on the root fs on the NFS server to make
a diskless root fs use the old client.

CAM-based ATA stack. It means that all legacy ATA drivers were
removed and replaced by respective CAM drivers. If you are using
ATA device names in /etc/fstab or other places, make sure to update
them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY,

where 'Y's are the sequential numbers starting from zero for each type
in order of detection, unless configured otherwise with tunables,
- Add shim to simplify migration to the CAM-based ATA. For each new adaX device in /dev/ create symbolic link with adY name, trying to mimic old ATA numbering. Imitation is not complete, but should be enough in most cases to mount file systems without touching /etc/fstab. - To know what behavior to mimic, restore ATA_STATIC_ID option in cases where it was present before. - Add some more details to UPDATING.
2011-04-26 17:01:49 +00:00
see cam(4)). There will be symbolic links created in /dev/ to map
old adX devices to the respective adaY. They should provide basic
compatibility for file systems mounting in most cases, but they do
not support old user-level APIs and do not have respective providers
in GEOM. Consider using updated management tools with new device names.
It is possible to load devices ahci, ata, siis and mvs as modules,
but option ATA_CAM should remain in kernel configuration to make ata
module work as CAM driver supporting legacy ATA controllers. Device ata
still can be used in modular fashion (atacore + ...). Modules atadisk
and atapi* are not used and won't affect operation in ATA_CAM mode.
Add obvious note that CAM drivers are required for using CAM ATA.
2011-04-27 08:53:52 +00:00
Note that to use CAM-based ATA kernel should include CAM devices
scbus, pass, da (or explicitly ada), cd and optionally others. All of
them are parts of the cam module.
Switch the GENERIC kernels for all architectures to the new CAM-based ATA stack. It means that all legacy ATA drivers are disabled and replaced by respective CAM drivers.

To use it you can load geom_raid kernel module and use graid(8) tool for management. Instead of /dev/arX device names, use /dev/raid/rX.

This patch changes the default NFS server to the new one, which was referred to as the experimental server. It also adds a new command line option "-o" to both mountd and nfsd that forces them to use the old/regular NFS server.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control support in mii(4): - Merge generic flow control advertisement (which can be enabled by passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD, IFM_FLOW isn't implemented as a global option via the "don't care mask" but instead as a media specific option this. This has the following advantages: o allows flow control advertisement with autonegotiation to be turned on and off via ifconfig(8) with the default typically being off (though MIIF_FORCEPAUSE has been added causing flow control to be always advertised, allowing to easily MFC this changes for drivers that previously used home-grown support for flow control that behaved that way without breaking POLA) o allows to deal with PHY drivers where flow control advertisement with manual selection doesn't work or at least isn't implemented, like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4), by setting MIIF_NOMANPAUSE o the available combinations of media options are readily available from the `ifconfig -m` output - Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so these are understood by ifconfig(8). o Make the master/slave support in mii(4) actually usable: - Change IFM_ETH_MASTER from being implemented as a global option via the "don't care mask" to a media specific one as it actually is only applicable to IFM_1000_T to date. - Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to actually configure manually selected slave mode (like we also do in the PHY specific implementations). - Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it is understood by ifconfig(8). o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4), e1000phy(4) and ip1000phy(4) to use the generic flow control support instead of home-grown solutions via IFM_FLAGs. This includes changing these PHY drivers and smcphy(4) to no longer unconditionally advertise support for flow control but only if the selected media has IFM_FLOW set (or MIIF_FORCEPAUSE is set) and implemented for these media variants, i.e. typically only for copper. o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0 and some IFM_FLAGn. o Switch brgphy(4) to add at least the the supported copper media based on the contents of the BMSR via mii_phy_add_media() instead of hardcoding them. The latter approach seems to have developed historically, besides causing unnecessary code duplication it was also undesirable because brgphy_mii_phy_auto() already based the capability advertisement on the contents of the BMSR though. o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not just BCM5701. Apparently this was a misinterpretation of a workaround in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but this doesn't mean we can't set these as well on other PHYs for manual media selection. o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so IFM_1000_T master mode support now is generally available with all PHY drivers. o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's not applicable there.

Generic IEEE 802.3 annex 31B full duplex flow control support has been
added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along
with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted
to take advantage of it instead of using custom implementations. This
means that these drivers now no longer unconditionally advertise
support for flow control but only do so if flow control is a selected
media option. This was implemented in the generic support that way in
order to allow flow control to be switched on and off via ifconfig(8)
with the PHY specific default to typically off in order to protect
from unwanted effects. Consequently, if you used flow control with
one of the above mentioned drivers you now need to explicitly enable
it, for example via:
ifconfig bge0 media auto mediaopt flowcontrol
Along with the above mentioned changes generic support for setting
1000baseT master mode also has been added and brgphy(4), ciphy(4),
e1000phy(4) as well as ip1000phy(4) have been converted to take
advantage of it. This means that these drivers now no longer take the
link0 parameter for selecting master mode but the master media option
has to be used instead, for example like in the following:
ifconfig bge0 media 1000baseT mediaopt full-duplex,master
Selection of master mode now is also available with all other PHY
drivers supporting 1000baseT.
This commit marks the first formal contribution of the "Five New TCP Congestion Control Algorithms for FreeBSD" FreeBSD Foundation funded project. More details about the project are available at: http://caia.swin.edu.au/freebsd/5cc/ - Add a KPI and supporting infrastructure to allow modular congestion control algorithms to be used in the net stack. Algorithms can maintain per-connection state if required, and connections maintain their own algorithm pointer, which allows different connections to concurrently use different algorithms. The TCP_CONGESTION socket option can be used with getsockopt()/setsockopt() to programmatically query or change the congestion control algorithm respectively from within an application at runtime. - Integrate the framework with the TCP stack in as least intrusive a manner as possible. Care was also taken to develop the framework in a way that should allow integration with other congestion aware transport protocols (e.g. SCTP) in the future. The hope is that we will one day be able to share a single set of congestion control algorithm modules between all congestion aware transport protocols. - Introduce a new congestion recovery (TF_CONGRECOVERY) state into the TCP stack and use it to decouple the meaning of recovery from a congestion event and recovery from packet loss (TF_FASTRECOVERY) a la RFC2581. ECN and delay based congestion control protocols don't generally need to recover from packet loss and need a different way to note a congestion recovery episode within the stack. - Remove the net.inet.tcp.newreno sysctl, which simplifies some portions of code and ensures the stack always uses the appropriate mechanisms for recovering from packet loss during a congestion recovery episode. - Extract the NewReno congestion control algorithm from the TCP stack and massage it into module form. NewReno is always built into the kernel and will remain the default algorithm for the forseeable future. Implementations of additional different algorithms will become available in the near future. - Bump __FreeBSD_version to 900025 and note in UPDATING that rebuilding code that relies on the size of "struct tcpcb" is required.

Split $ipv6_prefer into $ip6addrctl_policy and $ipv6_activate_all_interfaces. The $ip6addrctl_policy is a variable to choose a pre-defined address selection policy set by ip6addrctl(8). The keyword "ipv4_prefer" sets IPv4-preferred one described in Section 10.3, the keyword "ipv6_prefer" sets IPv6-preferred one in Section 2.1 in RFC 3484, respectively. When "AUTO" is specified, it attempts to read /etc/ip6addrctl.conf first. If it is found, it reads and installs it as a policy table. If not, either of the two pre-defined policy tables is chosen automatically according to $ipv6_activate_all_interfaces. When $ipv6_activate_all_interfaces=NO, interfaces which have no corresponding $ifconfig_IF_ipv6 is marked as IFDISABLED for security reason. The default values are ip6addrctl_policy=AUTO and ipv6_activate_all_interfaces=NO. Discussed with: ume and bz

The $ipv6_prefer variable in rc.conf(5) has been split into
$ip6addrctl_policy and $ipv6_activate_all_interfaces.
The $ip6addrctl_policy is a variable to choose a pre-defined
address selection policy set by ip6addrctl(8). A value
"ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The
default is "AUTO".
The $ipv6_activate_all_interfaces specifies whether IFDISABLED
flag (see an entry of 20090926) is set on an interface with no
corresponding $ifconfig_IF_ipv6 line. The default is "NO" for
security reason. If you want IPv6 link-local address on all
interfaces by default, set this to "YES".
The old ipv6_prefer="YES" is equivalent to
ipv6_activate_all_interfaces="YES" and
ip6addrctl_policy="ipv6_prefer".

Add BSD grep to the base system and make it our default grep. Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC), lower memory usage than GNU grep, GNU compatibility, BSD license. TODO: Performance is somewhat behind GNU grep but it is only significant for bigger searches. The reason is complex, the most important factor is that GNU grep uses lots of optimizations to improve the speed of the regex library. First, we need a modern regex library (practically by adopting TRE), add support for GNU-style non-standard regexes and then reevalute the performance issues and look for bottlenecks. In the meantime, for those, who need better performance, it is possible to build GNU grep by setting WITH_GNU_GREP.

BSD grep has been imported to the base system and it is built by
default. It is completely BSD licensed, highly GNU-compatible, uses
less memory than its GNU counterpart and has a small codebase.
However, it is slower than its GNU counterpart, which is mostly
noticeable for larger searches, for smaller ones it is measurable
but not significant. The reason is complex, the most important factor
is that we lack a modern and efficient regex library and GNU
overcomes this by optimizing the searches internally. Future work
on improving the regex performance is planned, for the meantime,
users that need better performance, can build GNU grep instead by
setting the WITH_GNU_GREP knob.

A new version of ZFS (version 15) has been merged to -HEAD.
This version uses a python library for the following subcommands:
zfs allow, zfs unallow, zfs groupspace, zfs userspace.
For full functionality of these commands the following port must
be installed: sysutils/py-zfs
On Alan's advice, rather than do a wholesale conversion on a single architecture from page queue lock to a hashed array of page locks (based on a patch by Jeff Roberson), I've implemented page lock support in the MI code and have only moved vm_page's hold_count out from under page queue mutex to page lock. This changes pmap_extract_and_hold on all pmaps. Supported by: Bitgravity Inc. Discussed with: alc, jeffr, and kib
2010-04-30 00:46:43 +00:00
20100429:
'vm_page's are now hashed by physical address to an array of mutexes.
Currently this is only used to serialize access to hold_count. Over
time the page queue mutex will be peeled away. This changes the size
of pmap on every architecture. And requires all callers of vm_page_hold
and vm_page_unhold to be updated.
WITH_CTF can now be specified in src.conf (not recommended, there are some problems with static executables), make.conf (would also affect ports which do not use GNU make and do not override the compile targets) or in the kernel config (via "makeoptions WITH_CTF=yes"). Additional (related) changes: - propagate WITH_CTF to module builds - do not add -g to the linker flags, it's a noop there anyway (at least according to the man page of ld) - do not add -g to CFLAGS unconditionally we need to have a look if it is really needed (IMO not) or if there is a way to add it only when WITH_CTF is used Note: ctfconvert / ctfmerge lines will not appear in the build output, to protect the innocent (those which do not build with WITH_CTF would see the shell-test and may think WITH_CTF is used).

Provide groundwork for 32-bit binary compatibility on non-x86 platforms, for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32 option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts of the kernel and enhances the freebsd32 compatibility code to support big-endian platforms.

20100113:
The utmp user accounting database has been replaced with utmpx,
the user accounting interface standardized by POSIX.
Unfortunately the semantics of utmp and utmpx don't match,
making it practically impossible to support both interfaces.
The user accounting database is used by tools like finger(1),
last(1), talk(1), w(1) and ac(8).
All applications in the base system use utmpx. This means only
local binaries (e.g. from the ports tree) may still use these
utmp database files. These applications must be rebuilt to make
use of utmpx.
After the system has been upgraded, it is safe to remove the old
log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*),
Add wtmpcvt(1). This utility allows users to convert their wtmp databases to the new format. It makes no sense for users to keep their wtmp log files if they are unable to view them. It basically copies ut_line into ut_id as well. This makes it possible for last(1) and ac(8) to match login records with their corresponding logout record.

assuming their contents is of no importance anymore. Old wtmp
databases can only be used by last(1) and ac(8) after they have
been converted to the new format using wtmpcvt(1).

Introduce the new kernel thread called "deadlock resolver". While the name is pretentious, a good explanation of its targets is reported in this 17 months old presentation e-mail: http://lists.freebsd.org/pipermail/freebsd-arch/2008-August/008452.html In order to implement it, the sq_type in sleepqueues is mandatory and not only compiled along with INVARIANTS option. Additively, a new sleepqueue function, sleepq_type() is added, returning the type of the sleepqueue linked to a wchan. Three new sysctls are added in order to configure the thread: debug.deadlkres.slptime_threshold debug.deadlkres.blktime_threshold debug.deadlkres.sleepfreq rappresenting the thresholds for sleep and block time that will lead to a deadlock matching (when exceeded), while the sleepfreq rappresents the number of seconds between 2 consecutive thread runnings. In order to enable the deadlock resolver thread recompile your kernel with the option DEADLKRES.

The rc.firewall and rc.firewall6 were unified, and
rc.firewall6 and rc.d/ip6fw were removed.
According to the removal of rc.d/ip6fw, ipv6_firewall_* rc
variables are obsoleted. Instead, the following new rc
variables are added to rc.d/ipfw:
firewall_client_net_ipv6, firewall_simple_iif_ipv6,
firewall_simple_inet_ipv6, firewall_simple_oif_ipv6,
firewall_simple_onet_ipv6, firewall_trusted_ipv6

Switch the default terminal emulation style to xterm for most platforms. Right now syscons(4) uses a cons25-style terminal emulator. The disadvantages of that are: - Little compatibility with embedded devices with serial interfaces. - Bad bandwidth efficiency, mainly because of the lack of scrolling regions. - A very hard transition path to support for modern character sets like UTF-8. Our terminal emulation library, libteken, has been supporting xterm-style terminal emulation for months, so flip the switch and make everyone use an xterm-style console driver. I still have to enable this on i386. Right now pc98 and i386 share the same /etc/ttys file. I'm not going to switch pc98, because it uses its own Kanji-capable cons25 emulator. IMPORTANT: What to do if things go wrong (i.e. graphical artifacts): - Run the application inside script(1), try to reduce the problem and send me the log file. - In the mean time, you can run `vidcontrol -T cons25' and `export TERM=cons25' so you can run applications the same way you did before. You can also build your kernel with `options TEKEN_CONS25' to make all virtual terminals use the cons25 emulator by default. Discussed on: current@

Fix several logic bugs in the previous IPv6 variable change and re-add $ipv6_enable support for backward compatibility. From UPDATING: 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF for IPv4. For aliases, $ifconfig_IF_aliasN should be used. Note that both variables need the "inet6" keyword at the head. Do not set $ipv6_network_interfaces manually if you do not understand what you are doing. It is not needed in most cases. $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but they are obsolete. 2. $ipv6_enable is obsolete. Use $ipv6_prefer and/or "inet6 accept_rtadv" keyword in ifconfig(8) instead. If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and all configured interfaces have "inet6 accept_rtadv" in the $ifconfig_IF_ipv6. These are for backward compatibility. 3. A new variable $ipv6_prefer has been added. If NO, IPv6 functionality of interfaces with no corresponding $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, and the default address selection policy of ip6addrctl(8) is the IPv4-preferred one (see rc.d/ip6addrctl for more details). Note that if you want to configure IPv6 functionality on the disabled interfaces after boot, first you need to clear the flag by using ifconfig(8) like: ifconfig em0 inet6 -ifdisabled If YES, the default address selection policy is set as IPv6-preferred. The default value of $ipv6_prefer is NO. 4. If your system need to receive Router Advertisement messages, define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) scripts automatically invoke rtsol(8) when the interface becomes UP. The Router Advertisement messages are used for SLAAC (State-Less Address AutoConfiguration).

Rework the credential code to support larger values of NGROUPS and NGROUPS_MAX, eliminate ABI dependencies on them, and raise the to 1024 and 1023 respectively. (Previously they were equal, but under a close reading of POSIX, NGROUPS_MAX was defined to be too large by 1 since it is the number of supplemental groups, not total number of groups.) The bulk of the change consists of converting the struct ucred member cr_groups from a static array to a pointer. Do the equivalent in kinfo_proc. Introduce new interfaces crcopysafe() and crsetgroups() for duplicating a process credential before modifying it and for setting group lists respectively. Both interfaces take care for the details of allocating groups array. crsetgroups() takes care of truncating the group list to the current maximum (NGROUPS) if necessary. In the future, crsetgroups() may be responsible for insuring invariants such as sorting the supplemental groups to allow groupmember() to be implemented as a binary search. Because we can not change struct xucred without breaking application ABIs, we leave it alone and introduce a new XU_NGROUPS value which is always 16 and is to be used or NGRPS as appropriate for things such as NFS which need to use no more than 16 groups. When feasible, truncate the group list rather than generating an error. Minor changes: - Reduce the number of hand rolled versions of groupmember(). - Do not assign to both cr_gid and cr_groups[0]. - Modify ipfw to cache ucreds instead of part of their contents since they are immutable once referenced by more than one entity.

NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024
respectively. As long as no more than 16 groups per process are used,
no changes should be visible. When more than 16 groups are used, old
binaries may fail if they call getgroups() or getgrouplist() with
statically sized storage. Recompiling will work around this, but
applications should be modified to use dynamically allocated storage
for group arrays as POSIX.1-2008 does not cap an implementation's
number of supported groups at NGROUPS_MAX+1 as previous versions did.
NFS and portalfs mounts may also be affected as the list of groups is
truncated to 16. Users of NFS who use more than 16 groups, should
take care that negative group permissions are not used on the exported
file systems as they will not be reliable unless a GSSAPI based
authentication method is used.

The compiling option ADAPTIVE_LOCKMGRS has been introduced. This
option compiles in the support for adaptive spinning for lockmgrs
which want to enable it. The lockinit() function now accepts the flag
LK_ADAPTIVE in order to make the lock object subject to adaptive
spinning when both held in write and read mode.
Introduce support for adaptive spinning in lockmgr. Actually, as it did receive few tuning, the support is disabled by default, but it can opt-in with the option ADAPTIVE_LOCKMGRS. Due to the nature of lockmgrs, adaptive spinning needs to be selectively enabled for any interested lockmgr. The support is bi-directional, or, in other ways, it will work in both cases if the lock is held in read or write way. In particular, the read path is passible of further tunning using the sysctls debug.lockmgr.retries and debug.lockmgr.loops . Ideally, such sysctls should be axed or compiled out before release. Addictionally note that adaptive spinning doesn't cope well with LK_SLEEPFAIL. The reason is that many (and probabilly all) consumers of LK_SLEEPFAIL are mainly interested in knowing if the interlock was dropped or not in order to reacquire it and re-test initial conditions. This directly interacts with adaptive spinning because lockmgr needs to drop the interlock while spinning in order to avoid a deadlock (further details in the comments inside the patch). Final note: finding someone willing to help on tuning this with relevant workloads would be either very important and appreciated. Tested by: jeff, pho Requested by: many

Introduce a mechanism for detecting calls from outbound path of the network stack when reentering the inbound path from netgraph, and force queueing of mbufs at the outbound netgraph node. The mechanism relies on two components. First, in netgraph nodes where outbound path of the network stack calls into netgraph, the current thread has to be appropriately marked using the new NG_OUTBOUND_THREAD_REF() macro before proceeding to call further into the netgraph topology, and unmarked using the NG_OUTBOUND_THREAD_UNREF() macro before returning to the caller. Second, netgraph nodes which can potentially reenter the network stack in the inbound path have to mark their inbound hooks using NG_HOOK_SET_TO_INBOUND() macro. The netgraph framework will then detect when there is a danger of a call graph looping back from outbound to inbound path via netgraph, and defer handing off the mbufs to the "inbound" node to a worker thread with a clean stack. In this first pass only the most obvious netgraph nodes have been updated to ensure no outbound to inbound calls can occur. Nodes such as ng_ipfw, ng_gif etc. should be further examined whether a potential for outbound to inbound call looping exists. This commit changes the layout of struct thread, but due to __FreeBSD_version number shortage a version bump has been omitted at this time, nevertheless kernel and modules have to be rebuilt.

While this patch introduces numerous placeholder destructor functions, many of those are currently incomplete, thus leaking memory or (even worse) failing to stop all running timers.

Add hierarchical jails. A jail may further virtualize its environment by creating a child jail, which is visible to that jail and to any parent jails. Child jails may be restricted more than their parents, but never less. Jail names reflect this hierarchy, being MIB-style dot-separated strings. Every thread now points to a jail, the default being prison0, which contains information about the physical system. Prison0's root directory is the same as rootvnode; its hostname is the same as the global hostname, and its securelevel replaces the global securelevel. Note that the variable "securelevel" has actually gone away, which should not cause any problems for code that properly uses securelevel_gt() and securelevel_ge(). Some jail-related permissions that were kept in global variables and set via sysctls are now per-jail settings.

Permit buiding kernels with options VIMAGE, restricted to only a single active network stack instance. Turning on options VIMAGE at compile time yields the following changes relative to default kernel build: 1) V_ accessor macros for virtualized variables resolve to structure fields via base pointers, instead of being resolved as fields in global structs or plain global variables. As an example, V_ifnet becomes: options VIMAGE: ((struct vnet_net *) vnet_net)->_ifnet default build: vnet_net_0._ifnet options VIMAGE_GLOBALS: ifnet 2) INIT_VNET_* macros will declare and set up base pointers to be used by V_ accessor macros, instead of resolving to whitespace: INIT_VNET_NET(ifp->if_vnet); becomes struct vnet_net *vnet_net = (ifp->if_vnet)->mod_data[VNET_MOD_NET]; 3) Memory for vnet modules registered via vnet_mod_register() is now allocated at run time in sys/kern/kern_vimage.c, instead of per vnet module structs being declared as globals. If required, vnet modules can now request the framework to provide them with allocated bzeroed memory by filling in the vmi_size field in their vmi_modinfo structures. 4) structs socket, ifnet, inpcbinfo, tcpcb and syncache_head are extended to hold a pointer to the parent vnet. options VIMAGE builds will fill in those fields as required. 5) curvnet is introduced as a new global variable in options VIMAGE builds, always pointing to the default and only struct vnet. 6) struct sysctl_oid has been extended with additional two fields to store major and minor virtualization module identifiers, oid_v_subs and oid_v_mod.

Bite the bullet, and make the IPv6 SSM and MLDv2 mega-commit: import from p4 bms_netdev. Summary of changes: * Connect netinet6/in6_mcast.c to build. The legacy KAME KPIs are mostly preserved. * Eliminate now dead code from ip6_output.c. Don't do mbuf bingo, we are not going to do RFC 2292 style CMSG tricks for multicast options as they are not required by any current IPv6 normative reference. * Refactor transports (UDP, raw_ip6) to do own mcast filtering. SCTP, TCP unaffected by this change. * Add ip6_msource, in6_msource structs to in6_var.h. * Hookup mld_ifinfo state to in6_ifextra, allocate from domifattach path. * Eliminate IN6_LOOKUP_MULTI(), it is no longer referenced. Kernel consumers which need this should use in6m_lookup(). * Refactor IPv6 socket group memberships to use a vector (like IPv4). * Update ifmcstat(8) for IPv6 SSM. * Add witness lock order for IN6_MULTI_LOCK. * Move IN6_MULTI_LOCK out of lower ip6_output()/ip6_input() paths. * Introduce IP6STAT_ADD/SUB/INC/DEC as per rwatson's IPv4 cleanup. * Update carp(4) for new IPv6 SSM KPIs. * Virtualize ip6_mrouter socket. Changes mostly localized to IPv6 MROUTING. * Don't do a local group lookup in MROUTING. * Kill unused KAME prototypes in6_purgemkludge(), in6_restoremkludge(). * Preserve KAME DAD timer jitter behaviour in MLDv1 compatibility mode. * Bump __FreeBSD_version to 800084. * Update UPDATING. NOTE WELL: * This code hasn't been tested against real MLDv2 queriers (yet), although the on-wire protocol has been verified in Wireshark. * There are a few unresolved issues in the socket layer APIs to do with scope ID propagation. * There is a LOR present in ip6_output()'s use of in6_setscope() which needs to be resolved. See comments in mld6.c. This is believed to be benign and can't be avoided for the moment without re-introducing an indirect netisr. This work was mostly derived from the IGMPv3 implementation, and has been sponsored by a third party.

20090429:
MLDv2 and Source-Specific Multicast (SSM) have been merged
to the IPv6 stack. VIMAGE hooks are in but not yet used.
The implementation of SSM within FreeBSD's IPv6 stack closely
follows the IPv4 implementation.
For kernel developers:
* The most important changes are that the ip6_output() and
ip6_input() paths no longer take the IN6_MULTI_LOCK,
and this lock has been downgraded to a non-recursive mutex.
* As with the changes to the IPv4 stack to support SSM, filtering
of inbound multicast traffic must now be performed by transport
protocols within the IPv6 stack. This does not apply to TCP and
SCTP, however, it does apply to UDP in IPv6 and raw IPv6.
* The KPIs used by IPv6 multicast are similar to those used by
the IPv4 stack, with the following differences:
* im6o_mc_filter() is analogous to imo_multicast_filter().
* The legacy KAME entry points in6_joingroup and in6_leavegroup()
are shimmed to in6_mc_join() and in6_mc_leave() respectively.
* IN6_LOOKUP_MULTI() has been deprecated and removed.
* IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs
for MLDv1 have an additional 'timer' argument which is used to
jitter the initial membership report for the solicited-node
multicast membership on-link.
* This is not strictly needed for MLDv2, which already jitters
its report transmissions. However, the 'timer' argument is
preserved in case MLDv1 is active on the interface.
* The KAME linked-list based IPv6 membership implementation has
been refactored to use a vector similar to that used by the IPv4
stack.
Code which maintains a list of its own multicast memberships
internally, e.g. carp, has been updated to reflect the new
semantics.
* There is a known Lock Order Reversal (LOR) due to in6_setscope()
acquiring the IF_AFDATA_LOCK and being called within ip6_output().
Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an
implementation constraint which needs to be addressed in HEAD.
For application developers:
* The changes are broadly similar to those made for the IPv4
stack.
* The use of IPv4 and IPv6 multicast socket options on the same
socket, using mapped addresses, HAS NOT been tested or supported.
* There are a number of issues with the implementation of various
IPv6 multicast APIs which need to be resolved in the API surface
before the implementation is fully compatible with KAME userland
use, and these are mostly to do with interface index treatment.
* The literature available discusses the use of either the delta / ASM
API with setsockopt(2)/getsockopt(2), or the full-state / ASM API
using setsourcefilter(3)/getsourcefilter(3). For more information
please refer to RFC 3768, 'Socket Interface Extensions for
Multicast Source Filters'.
* Applications which use the published RFC 3678 APIs should be fine.
For systems administrators:
* The mtest(8) utility has been refactored to support IPv6, in
addition to IPv4. Interface addresses are no longer accepted
as arguments, their names must be used instead. The utility
will map the interface name to its first IPv4 address as
returned by getifaddrs(3).
* The ifmcstat(8) utility has also been updated to print the MLDv2
endpoint state and source filter lists via sysctl(3).
* The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable
loopback of IPv6 multicast datagrams by default; it defaults to 1
to preserve the existing behaviour. Disabling multicast loopback is
recommended for optimal system performance.
* The IPv6 MROUTING code has been changed to examine this sysctl
instead of attempting to perform a group lookup before looping
back forwarded datagrams.

Introduce a number of changes to the MROUTING code. This is purely a forwarding plane cleanup; no control plane code is involved. Summary: * Split IPv4 and IPv6 MROUTING support. The static compile-time kernel option remains the same, however, the modules may now be built for IPv4 and IPv6 separately as ip_mroute_mod and ip6_mroute_mod. * Clean up the IPv4 multicast forwarding code to use BSD queue and hash table constructs. Don't build our own timer abstractions when ratecheck() and timevalclear() etc will do. * Expose the multicast forwarding cache (MFC) and virtual interface table (VIF) as sysctls, to reduce netstat's dependence on libkvm for this information for running kernels. * bandwidth meters however still require libkvm. * Make the MFC hash table size a boot/load-time tunable ULONG, net.inet.ip.mfchashsize (defaults to 256). * Remove unused members from struct vif and struct mfc. * Kill RSVP support, as no current RSVP implementation uses it. These stubs could be moved to raw_ip.c. * Don't share locks or initialization between IPv4 and IPv6. * Don't use a static struct route_in6 in ip6_mroute.c. The v6 code is still using a cached struct route_in6, this is moved to mif6 for the time being. * More cleanup remains to be merged from ip_mroute.c to ip6_mroute.c. v4 path tested using ports/net/mcast-tools. v6 changes are mostly mechanical locking and *have not* been tested. As these changes partially break some kernel ABIs, they will not be MFCed. There is a lot more work to be done here. Reviewed by: Pavlin Radoslavov

IGMPv3 and Source-Specific Multicast (SSM) have been merged

For kernel developers, the most important changes are that the
ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(),
and this lock has been downgraded to a non-recursive mutex.
Transport protocols (UDP, Raw IP) are now responsible for filtering
inbound multicast traffic according to group membership and source
filters. The imo_multicast_filter() KPI exists for this purpose.
Transports which do not use multicast (SCTP, TCP) already reject
multicast by default. Forwarding and receive performance may improve
as a mutex acquisition is no longer needed in the ip_input()
low-level input path. in_addmulti() and in_delmulti() are shimmed
to new KPIs which exist to support SSM in-kernel.
For application developers, it is recommended that loopback of
multicast datagrams be disabled for best performance, as this
will still cause the lock to be taken for each looped-back
datagram transmission. The net.inet.ip.mcast.loop sysctl may
be tuned to 0 to disable loopback by default; it defaults to 1
to preserve the existing behaviour.
For systems administrators, to obtain best performance with
multicast reception and multiple groups, it is always recommended
that a card with a suitably precise hash filter is used. Hash
collisions will still result in the lock being taken within the
transport protocol input path to check group membership.
If deploying FreeBSD in an environment with IGMP snooping switches,
it is recommended that the net.inet.igmp.sendlocal sysctl remain
enabled; this forces 224.0.0.0/24 group membership to be announced
via IGMP.
The size of 'struct igmpstat' has changed; netstat needs to be
recompiled to reflect this.

Remove the single global unlocked route cache ip6_forward_rt from the inet6 stack along with statistics and make sure we properly free the rt in all cases.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

For many years, FreeBSD's version of OpenSSH preferred DSA
over RSA for host and user authentication keys. With this

host keys even for previously known hosts. Users should
follow the usual procedure for verifying host keys before

Switch the default NFS mount mode from UDP to TCP. UDP mounts are a historical relic, and are no longer appropriate for either LAN or WAN mounting. At modern (gigabit and 10 gigabit) LAN speeds packet loss from socket buffer fill events is common, and sequence numbers wrap quickly enough that data corruption is possible. TCP solves both of these problems without imposing significant overhead. MFC after: 1 month

Our fts(3) API, as inherited from 4.4BSD, suffers from integer fields in FTS and FTSENT structs being too narrow. In addition, the narrow types creep from there into fts.c. As a result, fts(3) consumers, e.g., find(1) or rm(1), can't handle file trees an ordinary user can create, which can have security implications. To fix the historic implementation of fts(3), OpenBSD and NetBSD have already changed <fts.h> in somewhat incompatible ways, so we are free to do so, too. This change is a superset of changes from the other BSDs with a few more improvements. It doesn't touch fts(3) functionality; it just extends integer types used by it to match modern reality and the C standard. Here are its points: o For C object sizes, use size_t unless it's 100% certain that the object will be really small. (Note that fts(3) can construct pathnames _much_ longer than PATH_MAX for its consumers.) o Avoid the short types because on modern platforms using them results in larger and slower code. Change shorts to ints as follows: - For variables than count simple, limited things like states, use plain vanilla `int' as it's the type of choice in C. - For a limited number of bit flags use `unsigned' because signed bit-wise operations are implementation-defined, i.e., unportable, in C. o For things that should be at least 64 bits wide, use long long and not int64_t, as the latter is an optional type. See FTSENT.fts_number aka FTS.fts_bignum. Extending fts_number `to satisfy future needs' is pointless because there is fts_pointer, which can be used to link to arbitrary data from an FTSENT. However, there already are fts(3) consumers that require fts_number, or fts_bignum, have at least 64 bits in it, so we must allow for them. o For the tree depth, use `long'. This is a trade-off between making this field too wide and allowing for 64-bit inode numbers and/or chain-mounted filesystems. On the one hand, `long' is almost enough for 32-bit filesystems on a 32-bit platform (our ino_t is uint32_t now). On the other hand, platforms with a 64-bit (or wider) `long' will be ready for 64-bit inode numbers, as well as for several 32-bit filesystems mounted one under another. Note that fts_level has to be signed because -1 is a magic value for it, FTS_ROOTPARENTLEVEL. o For the `nlinks' local var in fts_build(), use `long'. The logic in fts_build() requires that `nlinks' be signed, but our nlink_t currently is uint16_t. Therefore let's make the signed var wide enough to be able to represent 2^16-1 in pure C99, and even 2^32-1 on a 64-bit platform. Perhaps the logic should be changed just to use nlink_t, but it can be done later w/o breaking fts(3) ABI any more because `nlinks' is just a local var. This commit also inludes supporting stuff for the fts change: o Preserve the old versions of fts(3) functions through libc symbol versioning because the old versions appeared in all our former releases. o Bump __FreeBSD_version just in case. There is a small chance that some ill-written 3-rd party apps may fail to build or work correctly if compiled after this change. o Update the fts(3) manpage accordingly. In particular, remove references to fts_bignum, which was a FreeBSD-specific hack to work around the too narrow types of FTSENT members. Now fts_number is at least 64 bits wide (long long) and fts_bignum is an undocumented alias for fts_number kept around for compatibility reasons. According to Google Code Search, the only big consumers of fts_bignum are in our own source tree, so they can be fixed easily to use fts_number. o Mention the change in src/UPDATING. PR: bin/104458 Approved by: re (quite a while ago) Discussed with: deischen (the symbol versioning part) Reviewed by: -arch (mostly silence); das (generally OK, but we didn't agree on some types used; assuming that no objections on -arch let me to stick to my opinion)

20080126:
The fts(3) structures have been changed to use adequate
integer types for their members and so to be able to cope
with huge file trees. The old fts(3) ABI is preserved
through symbol versioning in libc, so third-party binaries
using fts(3) should still work, although they will not take
advantage of the extended types. At the same time, some
third-party software might fail to build after this change
due to unportable assumptions made in its source code about
fts(3) structure members. Such software should be fixed
by its vendor or, in the worst case, in the ports tree.
FreeBSD_version 800015 marks this change for the unlikely
case that a portable fix is impossible.

When upgrading from one major version to another it is generally best
to upgrade to the latest code in the currently installed branch first,
then do an upgrade to the new branch. This is the best-tested upgrade
path, and has the highest probability of being successful. Please try
this approach before reporting problems with a major version upgrade.

ZFS notes
---------
When upgrading the boot ZFS pool to a new version, always follow
these two steps:
1.) recompile and reinstall the ZFS boot loader and boot block
(this is part of "make buildworld" and "make installworld")
2.) update the ZFS boot block on your boot drive
The following example updates the ZFS boot block on the first
partition (freebsd-boot) of a GPT partitioned drive ad0:
"gpart bootcode -p /boot/gptzfsboot -i 1 ad0"
Non-boot pools do not need these updates.
Add a section at the end called COMMON ITEMS. This is where we'll put those questions that come up all the time (eg, how do I build a kernel). This is intended to be a very brief reminder for people that are basically clueful what the steps are to do these common things. What it lacks in verbosity it makes up in terseness.

A simple make world is too dangerous for most upgrades. Instead, copy the updating from stable section, and remove the kludge-o-rounds that are in there. Sometimes make world is safe, sometimes not. Let's document the safe way to deal.

Suggest to run the delete-old target after the second mergemaster. If you run it before, your rc scripts may still reference old files/directories and if you are in the unlucky situation to have triggered a reboot (intentionally or not) between the delete-old run and the mergemaster, your system may not start anymore.

To cross-install current onto a separate partition
--------------------------------------------------
# In this approach we use a separate partition to hold
# current's root, 'usr', and 'var' directories. A partition
# holding "/", "/usr" and "/var" should be about 2GB in
# size.

2000-08-06 22:16:34 +00:00
Also, if you are tracking -current, you must be subscribed to
freebsd-current@freebsd.org. Make sure that before you update
your sources that you have read and understood all the recent
messages there. If in doubt, please track -stable which has
much fewer pitfalls.

[5] Usually this step is a noop. However, from time to time
you may need to do this if you get unknown user in the following
step. It never hurts to do it all the time. You may need to
install a new mergemaster (cd src/usr.sbin/mergemaster && make
install) after the buildworld before this step if you last updated
from current before 20020224 or from -stable before 20020408.

[6] This only deletes old files and directories. Old libraries
can be deleted by "make delete-old-libs", but you have to make
sure that no program is using those libraries anymore.

[8] In order to have a kernel that can run the 4.x binaries needed to
do an installworld, you must include the COMPAT_FREEBSD4 option in
your kernel. Failure to do so may leave you with a system that is
hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is
required to run the 5.x binaries on more recent kernels. And so on
for COMPAT_FREEBSD6 and COMPAT_FREEBSD7.
Mention the need to have COMPAT_FREEBSD4 in the kernel you use for the upgrade.

cvs prune empty directories.
If CPUTYPE is defined in your /etc/make.conf, make sure to use the
"?=" instead of the "=" assignment operator, so that buildworld can
override the CPUTYPE if it needs to.
MAKEOBJDIRPREFIX must be defined in an environment variable, and
not on the command line, or in /etc/make.conf. buildworld will
warn if it is improperly defined.
Add a section at the end called COMMON ITEMS. This is where we'll put those questions that come up all the time (eg, how do I build a kernel). This is intended to be a very brief reminder for people that are basically clueful what the steps are to do these common things. What it lacks in verbosity it makes up in terseness.
