Fix a bug in the description of the "p6-div" event. [1]
Update the description of the "p6-div" and "p6-mul" events according
to the "Intel(r) 64 and IA-32 Architectures Software Developers
Manual Volume 3B: System Programming Guide, Part 2, November 2006".
Reported by: Harald Servat <redcrash at gmail dot com> [1]
There are a couple of bugs in rev. 1.27:
1) The man page should describe the code, not the other way around.
2) Internal variables should not be documented or exposed, except in
controlled circumstances (i.e. - That's what the -C flag is for).
The variable should have been saved to the config file in save_config().
3) The next available userid doesn't get automatically updated. The
end-result is the same (user gets added with the correct uid),
but in an interactive session the default uid doesn't get updated in
the display.
So,
o Use the uidstart variable instead of uuid (bug #3)
o Actually save the variable to adduser.conf (bug #2)
o (bug #1 to be fixed in an upcomming commit to adduser.conf.5)
Now that libarchive is being built in more environments,
factor out the platform-specific configuration header a bit
more cleanly.

Fix a case where the multicast addresses were not removed from some ports. The
first port to be removed from the trunk would free the multicast list so
subsequent removed ports didnt have their multicast addresses removed.

Add a flag to struct pfs_vdata to mark the vnode as dead (e.g. process-
specific nodes when the process exits)
Move the vnode-cache-walking loop which was duplicated in pfs_exit() and
pfs_disable() into its own function, pfs_purge(), which looks for vnodes
marked as dead and / or belonging to the specified pfs_node and reclaims
them. Note that this loop is still extremely inefficient.
Add a comment in pfs_vncache_alloc() explaining why we have to purge the
vnode from the vnode cache before returning, in case anyone should be
tempted to remove the call to cache_purge().
Move the special handling for pfstype_root nodes into pfs_fileno_alloc()
and pfs_fileno_free() (the root node's fileno must always be 2). This
also fixes a bug where pfs_fileno_free() would reclaim the root node's
fileno, triggering a panic in the unr code, as that fileno was never
allocated from unr to begin with.
When destroying a pfs_node, release its fileno and purge it from the
vnode cache. I wish we could put off the call to pfs_purge() until
after the entire tree had been destroyed, but then we'd have vnodes
referencing freed pfs nodes. This probably doesn't matter while we're
still under Giant, but might become an issue later.
When destroying a pseudofs instance, destroy the tree before tearing
down the fileno allocator.
In pfs_mount(), acquire the mountpoint interlock when required.
Fix doc.1 build when NOPORTS is defined. This includes
the following ports tree changes:
- libtool13 removed.
- pkgconfig moved to pkg-config.
- Default dependency for USE_GHOSTSCRIPT changed from
ghostscript-gnu to ghostscript-gpl.
- Also added missing docproj dependencies.

Group the loop to acquire/release Giant with the WITNESS_SAVE/RESTORE under
a single conditional. The two operations are linked, but since the link
is not very direct, Coverity can't see it. Humans might also miss the
link as well. So, this isn't fixing any actual bugs, just improving
readability.

- Sync service names with IANA (http://www.iana.org/assignments/port-numbers).
The registration names for 5222(tcp,udp) and 5269(tcp,udp) was changed to
xmpp-client and xmpp-server correspondingly.
This inconsistency causes problems to applications developed on other
systems, as they tries to use port numbers from /etc/services as fallback.

Change the TCP timer system from using the callout system five times
directly to a merged model where only one callout, the next to fire,
is registered.
Instead of callout_reset(9) and callout_stop(9) the new function
tcp_timer_activate() is used which then internally manages the callout.
The single new callout is a mutex callout on inpcb simplifying the
locking a bit.
tcp_timer() is the called function which handles all race conditions
in one place and then dispatches the individual timer functions.
Add work around for hardware Tx checksum offload bug in Yukon II.
Yukon II generated corrupted TCP checksum for short TCP packets
that's less than 60 bytes in size(e.g. window probe packet, pure ACK
packet etc). Padding the frame with zeros to make the frame minimum
ethernet frame size didn't work at all. Instead of dropping Tx
checksum offload support we calculate TCP checksum with S/W method
when we encounter short TCP frames.
Fortunately it seems that short UDP datagrams appear to be handled
correctly by Yukon II.
While I'm here simplify ethernet/VLAN header size calculation logic.
If available, take UUID from smbios.system.uuid, if not fall back to
software-generated UUID. Store the result in /etc/hostid and use it in
the future. Perform simple UUID format check, as there is a lot of
hardware with broken UUIDs. The check should be improved to also eliminate
fake UUIDs like 00000000-0000-0000-0000-000000000000.
strchr() and strrchr() are already present in the kernel, but with less
popular names. Hence:
- comment current index() and rindex() functions, as these serve the same
functionality as, respectively, strchr() and strrchr() from userland;
- add inlined version of strchr() and strrchr(), as we tend to use them more
often;
- remove str[r]chr() definitions from ZFS code;

On i386 compile the back-end with EISA support as well as the EISA
front-end if the dpt(4) module is built along with a kernel that
includes eisa(4) or when compiling it stand-alone (logic based on
the corresponding ISA logic in sys/modules/sound/sound/Makefile).
As as side-effect this fixes the stand-alone build of the dpt(4)
module after dpt.h 1.17, dpt_eisa.c 1.22 and dpt_scsi.c 1.55.
A fix for the SG_GET_TIMEOUT function slipped into a previous commit by
accident. Remove the text describing the problem as it is no longer
relevant. Also give real implementations for the GET and SET ioctls.
Add a pfsync_syncpeer option to /etc/defaults/rc.conf and rc.conf(5),
which can be used to turn off multicast pfsync support, and enable
the transmission of directed PFSYNC (IP protocol: 240) packets to
a specific "sync peer" host.

Add a new privilege, PRIV_NETINET_REUSEPORT, which will replace superuser
checks to see whether bind() can reuse a port/address combination while
it's already in use (for some definition of use).
Remove unnecessary suser() check in the sysctl to set up ath_hal
logging: the sysctl framework will already have checked for privilege
if a sysctl value is being set.
When LK_NOWAIT is passed as argument to process_worklist_item(), this
does not prevent handle_workitem_remove() from recursing into a blocking
version. Add the dirrem to worklist instead of processing it now if this
is the case.
Try to stabilize ZFS with regard to memory consumption:
- Allow to shrink ARC down to 16MB (instead of 64MB).
- Set arc_max to 1/2 of kmem_map by default.
- Start freeing things earlier when low memory situation is detected.
- Serialize execution of arc_lowmem().
I decided to setup minimum ZFS memory requirements to 512MB of RAM and 256MB of
kmem_map size. If there is less RAM or kmem_map, a warning will be printed.
World is cruel, be no better. In other words: modern file system requires
modern hardware:)
From ZFS administration guide:
"Currently the minimum amount of memory recommended to install a Solaris
system is 512 Mbytes. However, for good ZFS performance, at least one
Gbyte or more of memory is recommended."
Add the trunk(4) driver for providing link aggregation, failover and fault
tolerance. This driver allows aggregation of multiple network interfaces as
one virtual interface using a number of different protocols/algorithms.
failover - Sends traffic through the secondary port if the master becomes
inactive.
fec - Supports Cisco Fast EtherChannel.
lacp - Supports the IEEE 802.3ad Link Aggregation Control Protocol
(LACP) and the Marker Protocol.
loadbalance - Static loadbalancing using an outgoing hash.
roundrobin - Distributes outgoing traffic using a round-robin scheduler
through all active ports.
This code was obtained from OpenBSD and this also includes 802.3ad LACP support
from agr(4) in NetBSD.
Considerably rework the ifmcstat utility.
* Build with or without INET, INET6, or KVM features.
* When built without KVM, the sysctl-based getifmaddrs() function
is used as the back-end for the utility.
* Reflect the fact that FreeBSD now uses the in_multi refcount as
a true refcount.
* Style.
The utility may now be run without super-user privilege, albeit with
a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.
Fix a compiler warning so hash.h can be included in the kernel. This changes
the args for hash32_stre and hash32_strne but there are no consumers in the
base system and openbgpd does not use it which the initial import was for.
