- Protect mnt_flag with mount interlock.
Ignore hostid check for root-on-ZFS configurations. Making hostid available
before the root is mounted is tricky and having it in /boot/ is not really
desire.

When we run into the syncache entry limits syncache_add() tries
to free the oldest entry in the current bucket row. The global
entry limit may be smaller than the bucket rows and their limit
combined however. Thus only try to free a syncache entry if we
found one in this bucket row.
When trying to allocate a PnP BIOS memory resource, the code loops trying
to move up the start address until the allocation succeeds. If the
alignment of the resource was 0, then the code would keep trying the same
request in an infinite loop and hang. Force the request to always move
start up by at least 1 byte each time through the loop.
Change $P4$ ID strings to P4 ID strings so that they are not auto-expanded
when integrated back into Perforce. This avoids unnecessary conflicts
during the loopback of files maintained in Perforce.
Shorten text string for ip_fw2 dynamic rules zone by removing the word
"zone", which is generally not present in zone names. This reduces the
incidence of line-wrapping in "vmstat -z " using 80-column displays.
Don't use spinlocks here. The iicbus transactions can take a long
time, and this prevents interrupts (say for Hz/hardclock) from
happening. Time stands still during the transfers...
Rename the trunk(4) driver to lagg(4) as it is too similar to vlan trunking.
The name trunk is misused as the networking term trunk means carrying multiple
VLANs over a single connection. The IEEE standard for link aggregation (802.3
section 3) does not talk about 'trunk' at all while it is used throughout IEEE
802.1Q in describing vlans.
The lagg(4) driver provides link aggregation, failover and fault tolerance.
- Add a 'show rman <rm>' DDB command to dump the resources in a resource
manager similar to 'devinfo -u'.
- Add a 'show allrman' DDB command that effectively does 'show rman' on all
resource managers in the system.
New release notes: sx(9) lock improvements, T/TCP support in finger(1)
gone, libarchive(3) ar file support, rpc.lockd(8)/rpc.statd(8) -P (+MFC),
top(1) -a.
For the XPT_SASYNC_CB operation, only decouple the broadcast to the bus
and device lists instead of decoupling the whole operation. This avoids
problems with SIMs going away.
Vendor import TrustedBSD OpenBSM 1.0 alpha 14, with the following change
history notes since the last import:
OpenBSM 1.0 alpha 14
- Fix endian issues when processing IPv6 addresses for extended subject
and process tokens.
- gcc41 warnings clean.
- Teach audit_submit(3) about getaudit_addr(2).
- Add support for zonename tokens.
OpenBSM 1.0 alpha 13
- compat/clock_gettime.h now provides a compatibility implementation of
clock_gettime(), which fixes building on Mac OS X.
- Countless man page improvements, markup fixes, content fixs, etc.
- XML printing support via "praudit -x".
- audit.log.5 expanded to include additional BSM token types.
- Added encoding and decoding routines for process64_ex, process32_ex,
subject32_ex, header64, and attr64 tokens.
- Additional audit event identifiers for listen, mlockall/munlockall,
getpath, POSIX message queues, and mandatory access control.
Uncomment forgotten check. Without this check in-place, ZFS will panic on
unload instead of returning EBUSY. This check tells if there are mounted
ZFS file systems or not. We can't unload if there are mounted file systems.

In libarchive: Downgrade ARCHIVE_FATAL and ARCHIVE_FAILED errors which
occur on the write side of extracting a file to ARCHIVE_WARN errors
when returning them from archive_read_extract.
In bsdtar: Use the return code from archive_read_data_into_fd and
archive_read_extract to determine whether we should continue trying to
extract an archive after one of the entries fails.
This commit makes extracting a truncated tarball complain once about
the archive being truncated, instead of complaining twice (once when
trying to extract an entry, and once when trying to seek to the next
entry).
Add an entry for AUT_ZONENAME and the prototype for the au_to_zonename()
function that will be implemented shortly. This is being done for the

Instead of stating GIANT_REQUIRED, just acquire and release Giant where
needed. This does not make a difference now, but will when procfs is

Don't reset uio_offset to 0 before returning. Instead, refuse to service
requests where uio_offset is not 0 to begin with. This fixes a long-
standing bug where e.g. 'cat /proc/$$/regs' would loop forever.
- Add more comments to sctps_stats struture in sctp_uio.h
- Fix bug that prevented EEOR mode from working
and simplified the can_we_split code in the process.
- Reduce lock contention for the tcb_send_lock. I did
this especially for EEOR mode, still need to look at
why I need a lock when removing from the tailq and the
->next is NOT null. A lock fixes it but it implies a
bug yet exists.
- Activated Andre's proposed changes to better use the mbuf
infrastructure.
- Fixed places that were not using the aloc macro's to take
advantage of the per assoc cache.
- Adds ifdef fix so any logging will enable stat_logging to
get the right data structures in place (suggested by Max Laier).
Committing regression tests for all implemented nsswitch databases.
Detailed description and instructions are in the README file.
This work had been basically done during GSoC 2006.
Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM. Drivers that are not yet MPSAFE register Giant and operate as
usual. RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.
Force commit to actually document what was changed:
At some point in ZFS porting cycle I wasn't able to open snapshot datasets
in DS_MODE_PRIMARY mode and I changed it to DS_MODE_STANDARD. It seems
that it works just fine with DS_MODE_PRIMARY mode now, but I don't really
know what have changed.
Overhaul of 'ar' support:
* use "AR_GNU" as the format name instead of AR_SVR4 (it's what everyone is going to call it anyway)
* Simplify numeric parsing to unsigned (none of the numeric values should ever be negative); don't run off end of numeric fields.
* Finish parsing the common header fields before the next I/O request (which might dump the contents)
* Be smarter about format guessing and trimming filenames.
* Most of the magic values are only used in one place, so just inline them.
* Many more comments.
* Be smarter about handling damaged entries; return something reasonable.
* Call it a "filename table" instead of a "string table"
* Update tests.
Enable selection of 'ar', 'arbsd', and 'argnu' formats by name
(this allows bsdtar to create ar format archives).
The 'ar' writer still needs some work; it should reject
entries that aren't regular files and should probably also
strip leading paths from filenames.

Further pseudofs improvements:
The pfs_info mutex is only needed to lock pi_unrhdr. Everything else
in struct pfs_info is modified only while Giant is held (during
vfs_init() / vfs_uninit()); add assertions to that effect.
Simplify pfs_destroy somewhat.
Remove superfluous arguments from pfs_fileno_{alloc,free}(), and the
assertions which were added in the previous commit to ensure they were
consistent.
Assert that Giant is held while the vnode cache is initialized and
destroyed. Also assert that the cache is empty when it is destroyed.
Rename the vnode cache mutex for consistency.
Fix a long-standing bug in pfs_getattr(): it would uncritically return
the node's pn_fileno as st_ino. This would result in st_ino being 0
if the node had not previously been visited by readdir(), and also in
an incorrect st_ino for process directories and any files contained
therein. Correct this by abstracting the fileno manipulations
previously done in pfs_readdir() into a new function, pfs_fileno(),
which is used by both pfs_getattr() and pfs_readdir().
Cleanup sysconf(3) a bit. sysconf(3) assumes in some places it operates
on int, but in fact it should operate on long.
- Introduce 'lvalue' variable, which is long.
- Fix _SC_XOPEN_SHM for 64bit archs.

- Use lvalue for pathconf(3), as it returns long.
- Cast value explicitly to long on return.
