the last message on the send stream was "null" but still
there, a state we allow, we could get hung and not clean
it up and wait for the shutdown guard timer to clear the
association without a graceful close. Fix this so that
that we properly clean up.
- Added support for Multiple ASCONF per new RFC. We only
(so far) accept input of these and cannot yet generate
a multi-asconf.
- Sysctl'd support for experimental Fast Handover feature. Always
disabled unless sysctl or socket option changes to enable.
- Error case in add-ip where the peer supports AUTH and ADD-IP
but does NOT require AUTH of ASCONF/ASCONF-ACK. We need to
ABORT in this case.
- According to the Kyoto summit of socket api developers
(Solaris, Linux, BSD). We need to have:
o non-eeor mode messages be atomic - Fixed
o Allow implicit setup of an assoc in 1-2-1 model if
using the sctp_**() send calls - Fixed
o Get rid of HAVE_XXX declarations - Done
o add a sctp_pr_policy in hole in sndrcvinfo structure - Done
o add a PR_SCTP_POLICY_VALID type flag - yet to-do in a future patch!
- Optimize sctp6 calls to reuse code in sctp_usrreq. Also optimize
when we close sending out the data and disabling Nagle.
- Change key concatenation order to match the auth RFC
- When sending OOTB shutdown_complete always do csum.
- Don't send PKT-DROP to a PKT-DROP
- For abort chunks just always checksums same for
shutdown-complete.
- inpcb_free front state had a bug where in queue
data could wedge an assoc. We need to just abandon
ones in front states (free_assoc).
- If a peer sends us a 64k abort, we would try to
assemble a response packet which may be larger than
64k. This then would be dropped by IP. Instead make
a "minimum" size for us 64k-2k (we want at least
2k for our initack). If we receive such an init
discard it early without all the processing.
- When we peel off we must increment the tcb ref count
to keep it from being freed from underneath us.
- handling fwd-tsn had bugs that caused memory overwrites
when given faulty data, fixed so can't happen and we
also stop at the first bad stream no.
- Fixed so comm-up generates the adaption indication.
- peeloff did not get the hmac params copied.
- fix it so we lock the addr list when doing src-addr selection
(in future we need to use a multi-reader/one writer lock here)
- During lowlevel output, we could end up with a _l_addr set
to null if the iterator is calling the output routine. This
means we would possibly crash when we gather the MTU info.
Fix so we only do the gather where we have a src address
cached.
- we need to be sure to set abort flag on conn state when
we receive an abort.
- peeloff could leak a socket. Moved code so the close will
find the socket if the peeloff fails (uipc_syscalls.c)

So that it does not send the "null" data mbuf out and cause

- PD-API point needs to be invoked >= not just > to conform to socket api

- move M_NOTIFICATION to use M_PROTO5.
- PEER_ADDR_PARAMS did not fail properly if you specify an address
that is not in the association with a valid assoc_id. This meant
you got or set the stcb level values instead of the destination
you thought you were going to get/set. Now validate if the
stcb is non-null and the net is NULL that the sa_family is
set and the address is unspecified otherwise return an error.
- The thread based iterator could crash if associations were freed
at the exact time it was running. rework the worker thread to
use the increment/decrement to prevent this and no longer use
the markers that the timer based iterator uses.
- Fix the memleak in sctp_add_addr_to_vrf() for the case when it is
detected that ifa is already pointing to a ifn.
- Fix it so that if someone is so insane that they drop the
send window below the minimal add mark, they still can send.
- Changed all state for associations to use mask safe macro.
- During front states in association freeing in sctp_inpcbfree, we
had a locking problem where locks were not in place where they
should have been.
- Free association calls were not testing the return value in
sctp_inpcb_free() properly... others should be cast void returns
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
that M_PROTO5 does not have a problem between SCTP and the 802.11
stuff (which is the only other place its used).
- Fixed lock order reversal and missing atomic protection around
locked_tcb during association lookup and the 1-2-1 model.
- Added debug to source address selection.
- V6 output must always do checksum even for loopback.
- Remove more locks around inp that are not needed for an atomically
added/subtracted ref count.
- slight optimization in the way we zero the array in sctp_sack_check()
- It was possible to respond to a ABORT() with bad checksum with
a PKT-DROP. This lead to a PKT-DROP/ABORT war. Add code to NOT
send a PKT-DROP to any ABORT().
- 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.
- Added threshold managment logging.
- If the user picked just the right size, that just filled the send
window minus one mtu, we would enter a forever loop not copying and
at the same time not blocking. Change from < to <= solves this.
- Sysctl added to control the fragment interleave level which defaults
to 1.
- My rwnd control was not being used to control the rwnd properly (we
did not add and subtract to it :-() this is now fixed so we handle
small messages (1 byte etc) better to bring our rwnd down more
slowly.

ICMP error message, do not access th_flags. The field is beyond
the first eight bytes of the header that are required to be present
and were pulled up in the mbuf.
A random value of th_flags can have TH_SYN set, which made the
sequence number comparison not apply the window scaling factor,
which led to legitimate ICMP(v6) packets getting blocked with
"BAD ICMP" debug log messages (if enabled with pfctl -xm), thus
breaking PMTU discovery.
Triggering the bug requires TCP window scaling to be enabled
(sysctl net.inet.tcp.rfc1323, enabled by default) on both end-
points of the TCP connection. Large scaling factors increase
the probability of triggering the bug.

Unbreak xfs mount by just ignoring the error if vfs_getopts() sets the

GNU tar 1.17's implementation of --posix --sparse,
at the cost of losing compatibility with GNU tar 1.16.
Fortunately, the 1.17 implementation actually makes sense,
so the libarchive code is now a bit more straightforward
than before.
Background: GNU tar 1.16 defined a new way to store
sparse files in --posix archives. Unfortunately,
the implementation incorrectly inserted several
blocks of null padding after each such entry.
As a result, non-GNU tar implementations saw the
archive as truncated after any sparse entry.
This was fixed in GNU tar 1.17 at the cost of
losing compatibility with GNU tar 1.16 for this
new format (which is not the default, so hopefully
rarely used). Libarchive recently gained support
for reading the GNU tar 1.16 formats; this commit
updates it to read the GNU tar 1.17 variant instead.
