value, so we don't run out of KVA. The default vnodes limit fits better for
UFS, but ZFS allocated more file system specific memory for a vnode than UFS.
Don't touch vnodes limit if we detect it was tuned by system administrator
and restore original value when ZFS is unloaded.
This isn't final fix, but before we implement something better, this will
help to stabilize ZFS under heavy load on i386.

work present in FreeBSD 7.0 to refine the kernel privilege model:
- Introduce support for jail as a testing variable, in order to
confirm that privileges are properly restricted in the jail
environment.
- Restructure overall testing approach so that privilege and jail
conditions are set in the testing infrastructure before tests
are invoked, and done so in a custom-created process to isolate
the impact of tests from each other in a more consistent way.
- Tests now provide setup and cleanup hooks that occur before and
after the test runs.
- New privilege tests are now present for several audit
privileges, several credential management privileges, dmesg
buffer reading privilege, and netinet raw socket creation.
- Other existing tests are restructured and generally improved as
a result of better framework structure and jail as a variable.
For exampe, we now test that certain sysctls are writable only
outside jail, while others are writable within jail. On a
similar note, privileges relating to setting UFS file flags are
now better exercised, as with the right to chmod and utimes
files.

- EMSGSIZE is not being returned in non-blocking mode
and needs a small tweak to look if the msg would
ever fit when returning EWOULDBLOCK.
- FWD-TSN has a bug in stream processing which could
cause a panic. This is a follow on to the codenomicon
fix.
- PDAPI level 1 and 2 do not work unless the reader
gets his returned buffer full. Fix so we can break
out when at level 1 or 2.
- Fix fast-handoff features to copy across properly on
accepted sockets
- Fix sctp_peeloff() system call when no true system call
exists to screen arguments for errors. In cases where a
real system call exists the system call itself does this.
- Fix raddr leak in recent add-ip code change for bundled
asconfs (even when non-bundled asconfs are received)
- Make sure ipi_addr lock is held when walking global addr
list. Need to change this lock type to a rwlock().
- Add don't wake flag on both input and output when the
socket is closing.
- When deleting an address verify the interface is correct
before allowing the delete to process. This protects panda
and unnumbered.
- Clean up old sysctl stuff and get rid of the old Open/Net
BSD structures.
- Add a function to watch the ranges in the sysctl sets.
- When appending in the reassembly queue, validate that
the assoc has not gone to about to be freed. If so
(in the middle) abort out. Note this especially effects
MAC I think due to the lock/unlock they do (or with
LOCK testing in place).
- Netstat patch to get rid of warnings.
- Make sure that no data gets queued to inactive/unconfirmed
destinations. This especially effect CMT but also makes a
impact on regular SCTP as well.
- During init collision when we detect seq number out
of sync we need to treat it like Case C and discard
the cookie (no invarient needed here).
- Atomic access to the random store.
- When we declare a vtag good, we need to shove it
into the time wait hash to prevent further use. When
the tag is put into the assoc hash, we need to remove it
from the twait hash (where it will surely be). This prevents
duplicate tag assignments.
- Move decr-ref count to better protect sysctl out of
data.
- ltrace error corrections in sctp6_usrreq.c
- Add hook for interface up/down to be sent to us.
- Make sysctl() exported structures independent of processor
architecture.
- Fix route and src addr cache clearing for delete address case.
- Make sure address marked SCTP_DEL_IP_ADDRESS is never selected
as src addr.
- in icmp handling fixed so we actually look at the icmp codes
to figure out what to do.
- Modified mobility code.
Reception of DELETE IP ADDRESS for a primary destination and
SET PRIMARY for a new primary destination is used for
retransmission trigger to the new primary destination.
Also, in this case, destination of chunks in send_queue are
changed to the new primary destination.
- Fix so that we disallow sending by mbuf to ever have EEOR
mode set upon it.

get used in BSD when we compile with lock testing. These

It also allows us to test (with witness) the locking used

TCP timers as a single timer, but retain the API changes necessary to
reintroduce this change. This will back out the source of at least two
reported problems: lock leaks in certain timer edge cases, and TCP timers
continuing to fire after a connection has closed (a bug previously fixed and
then reintroduced with the timer rewrite).
In a follow-up commit, some minor restylings and comment changes performed
after the TCP timer rewrite will be reapplied, and a further change to allow
the TCP timer rewrite to be added back without disturbing the ABI. The new
design is believed to be a good thing, but the outstanding issues are
leading to significant stability/correctness problems that are holding
up 7.0.
