Add SCSI READ CAPACITY support to camcontrol. The new 'readcap' subcommand
will automatically issue the 16 byte verison of read capacity if the device
in question is larger than 2TB.
There are also a number of output options here (last block, number of
blocks, human readable) that should meet most needs, and also aid in
scripting.
Do not set the RTF_GATEWAY flag if RTF_LLINFO is set, it doesn't make much
sense in that context, and leads to unusable routes.
This should unbreak bootpd.

- 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.
- Locking compatiability changes. This involves adding
additional flags to many function calls. The flags only
get used in BSD when we compile with lock testing. These
flags allow apple to escape the "giant" lock it holds on
the socket and have more fine-grained locking in the NKE.
It also allows us to test (with witness) the locking used
by apple via a compile switch (manually applied).
Back out tcp_timer.c:1.93 and associated changes that reimplemented the many
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.
This patch was generated by silby, but is being committed by proxy due to
poor network connectivity for silby this week.

o Revamp the sparc64 interrupt code in order to be able to interface
with the INTR_FILTER-enabled MI code. Basically this consists of
registering an interrupt controller (of which there can be multiple
and optionally different ones either per host-to-foo bridge or shared
amongst host-to-foo bridges in any one machine) along with an interrupt
vector as specific argument for all the interrupt vectors used by a
given host-to-foo bridge (roughly similar to registering interrupt
sources on amd64 and i386), providing functions to enable, clear and
disable the interrupts of the children beneath the bridge.
This also includes:
- No longer entering a critical section in tl0_intr() and tl1_intr()
for executing interrupt handlers but rather let the handlers enter
it themselves so in the case of intr_event_handle() we don't enter
a nested critical section.
- Adding infrastructure for binding delivery of interrupt vectors to
specific CPUs which later on can be interfaced with the code from
amd64/i386 for binding interrupts to specific CPUs.
- Getting rid of the wrapper hack introduced along the lines of the
API changes for INTR_FILTER which as a side-effect caused interrupts
associated with ithread handlers only to get the elevated priority
of those associated with filters ("fast handlers") (this removes the
hack also in the non-INTR_FILTER case).
- Disabling (by not clearing) an interrupt in the interrupt controller
until all associated handlers have been executed, which is crucial
for the typical locking strategy of NIC drivers in order to work
correctly in case of shared interrupts. This was a more or less
theoretical problem on sparc64 though, as shared interrupts are
rather uncommon there except for the on-board SCCs and UARTs.
Note that due to the behavior of at least of some of the interrupt
controllers used on sparc64 an enable+EOI instead of a disable+EOI
approach (as implied by the INTR_FILTER MI code and implemented on
other architectures) is used as the latter can cause lost interrupts
or in the worst case interrupt starvation.
o Correct a typo in sbus_alloc_resource() which caused (pass-through)
allocations to only work down to the grandchildren of the bus, which
wasn't a real problem so far as we don't support any devices which are
great-grandchildren or greater of a U2S bridge, yet.
o In fhc(4) use bus_{read,write}_4() instead of bus_space_{read,write}_4()
in order to get rid of sc_bh and sc_bt in the fhc_softc. Also get rid
of some other unneeded members in fhc_softc.

This is an update to the new Intel 10G 82598 driver.
The first drop was Beta, this code is expected to be the release version.
Note that this driver code will build in either 6.2 or 7. If you
use the code in 6.2 you will not get TSO or MSI/X support but it will
function in a legacy mode.
In userland_sysctl(), call useracc() with the actual newlen value to be
used, rather than the one passed via 'req', which may not reflect a
rewrite. This call to useracc() is redundant to validation performed by
later copyin()/copyout() calls, so there isn't a security issue here,
but this could technically lead to excessive validation of addresses if
the length in newlen is shorter than req.newlen.

Fix races in msdosfs_lookup() and msdosfs_readdir(). These functions
can easily block in bread(), and then there was nothing to prevent the
static buffer (nambuf_{ptr,len,last_id}) being clobbered by another
thread.
The effects of the bug seem to have been limited to failed lookups and
mangled names in readdir(), since Giant locking provides enough
serialization to prevent concurrent calls to the functions that access
the buffer. They were very obvious for multiple concurrent tree walks,
especially with a small cluster size.
The bug was introduced in msdosfs_conv.c 1.34 and associated changes,
and is in all releases starting with 5.2.
The fix is to allocate the buffer as a local variable and pass around
pointers to it like "_r" functions in libc do. Stack use from this
is large but not too large. This also fixes a memory leak on module
unload.

Close a race that snuck in with the recent changes to fix a LOR between
the callout_lock spin lock and the sleepqueue spin locks. In the fix,
callout_drain() has to drop the callout_lock so it can acquire the
sleepqueue lock. The state of the callout can change while the
callout_lock is held however (for example, it can be rescheduled via
callout_reset()). The previous code assumed that the only state change
that could happen is that the callout could finish executing. This change
alters callout_drain() to effectively restart and recheck everything
after it acquires the sleepqueue lock thus handling all the possible
states that the callout could be in after any changes while callout_lock
was dropped.

where we don't care about the return value.
- If a reference count is held on an assoc, even from the "force free"
we should not do the actual free.. but instead let the timer
free it.
- When we enter sctp_input(), if the SCTP_ASOC_ABOUT_TO_BE_FREED
flag is set, we must NOT process the packet but handle it like
ootb. This is because while freeing an assoc we release the
locks to get all the higher order locks so we can purge all
the hash tables. This leaves a hole if a packet comes in
just at that point. Now sctp_common_input_processing() will
call the ootb code in such a case.
- Change MBUF M_NOTIFICATION to use M_PROTO5 (per Sam L). This makes
it so we don't have a conflict (I think this is a covertity change).
We made this change AFTER some conversation and looking to make sure

- Add an option for local logging (useful for macintosh or when
you need better performing during debugging). Note no commands
are here to get the log info, you must just use kgdb.
- The timer code needs to be aware of if it needs to call
sctp_sack_check() to slide the maps and adjust the cum-ack.
This is because it may be out of sync cum-ack wise.
