module; the ath module now brings in the hal support. Kernel
config files are almost backwards compatible; supplying
device ath_hal
gives you the same chip support that the binary hal did but you
must also include
options AH_SUPPORT_AR5416
to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

by getaudit(2). Some applications such has su, id will interpret E2BIG as
requiring the use of getaudit_addr(2) to pull extended audit state (ip6)
from the kernel.
This change un-breaks the ABI when auditing has been activated on a system
and the users are logged in via ip6.
This is a RELENG_7_1 candidate.

o eliminate private state indexed by 802.11 rate codes; use the hal's
rate tables directly to get the same info
o calculate a mask of operational rates to optimize lookups and checks
(instead of using for loops and similar)
o optimize size bin operations
o ignore rates marked as "do not use" in the hal phy tables
o fix bug that caused upshifting to break in 11g once the rate dropped
below 11Mb/s
o add more intelligent multi-rate tx schedules
o add support for 1/2 and 1/4 width channels
o add dev.ath.X.sample_stats sysctl to dump runtime statistics to the console
(needs to go up to a user app)
o export more tuning knobs via sysctls (still a couple of magic constants)
necessary workarounds, add code to detect these hangs and distinguish
them from other events; note this code is only invoked for anomalous
conditions and (at the moment) is a noop because the hang detection
code is in a new hal that's coming shortly

Add a custom version of copyiniov() to deal with the 32-bit iovec
pointers from userland (to be used later).
Adjust prototypes for linux_readv() and linux_writev() to use new

use ulong for fd (why ?).

Bring in updated jail support from bz_jail branch.
This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..
SCTP support was updated and supports IPv6 in jails as well.
Cpuset support permits jails to be bound to specific processor
sets after creation.
Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.
DDB 'show jails' command was added to aid debugging.
Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.
Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.
Bump __FreeBSD_version for the afore mentioned and in kernel changes.
Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
suggestions and review of most of the patch at various stages.

to the fs, but before a vnode on the fs is locked, unmount may free fs
structures, causing access to destroyed data and freed memory.
Introduce a vfs_busymp() function that looks up and busies found
fs while mountlist_mtx is held. Use it in nfsrv_fhtovp() and in the
implementation of the handle syscalls.
Two other uses of the vfs_getvfs() in the vfs_subr.c, namely in
sysctl_vfs_ctl and vfs_getnewfsid seems to be ok. In particular,
sysctl_vfs_ctl is protected by Giant by being a non-sleeping sysctl
handler, that prevents Giant-locked unmount code to interfere with it.
