protocol. RFCOMM is a SOCK_STREAM protocol not SOCK_SEQPACKET. This was a
serious bug caused by cut-and-paste. I'm surprised it did not bite me before.
Dunce hat goes to me.

debug.mpsafevm=1 by default on sparc64,
ixgb(4) MPSAFE,
core dump of natd(8) w/ -reverse fixed,
libarchive zip support improved, and
rexecd(8) root login problem fixed.
EA bit is set in hdr->length (16-bit length). This currently has no effect
on the rest of the code. It just fixes the debug message.

we have a non-NULL args.rule. If the same packet later is subject to "tee"
rule, its original is sent again into ipfw_chk() and it reenters at the same
rule. This leads to infinite loop and frozen router.
Assign args.rule to NULL, any time we are going to send packet back to
ipfw_chk() after a tee rule. This is a temporary workaround, which we
will leave for RELENG_5. In HEAD we are going to make divert(4) save
next rule the same way as dummynet(4) does.

to root cause on exactly how this happens.
- If the assert is disabled, we presently try to handle this case, but the
BUF_UNLOCK was missing. Thus, if this condition ever hit we would leak
a buf lock.
Many thanks to Peter Holm for all his help in finding this bug. He really
put more effort into it than I did.
* Handles entries with compressed size >2GB (signed/unsigned cleanup)
* Handles entries with compressed size >4GB ("ZIP64" extension)
* Handles Unix extensions (ctime, atime, mtime, mode, uid, etc)
* Format-specific "skip data" override allows ZIP reader to skip
entries without decompressing them, which makes "tar -t"
a lot faster.
* Handles "length-at-end" entries generated by, e.g., "zip -r - foo"
Many thanks to: Dan Nelson, who contributed the code and test files for
the first three items above and suggested the fourth.
the register values coming back from sigreturn(2). Normally this wouldn't
matter because the 32 bit environment would truncate the upper 32 bits
and re-save the truncated values at the next trap. However, if we got
a fast second signal and it was pending while we were returning from
sigreturn(2) in the signal trampoline, we'd never have had a chance to
truncate the bogus values in 32 bit mode, and the new sendsig would get
an EFAULT when trying to write to the bogus user stack address.
Functional changes:
- Cut struct source_hookinfo. Just use hook_p pointer.
- Remove "start_now" command. "start" command now requires number of
packets to send as argument. "start" command actually starts sending.
Move the code that actually starts sending from ng_source_rcvmsg()
to ng_source_start().
- Remove check for NG_SOURCE_ACTIVE in ng_source_stop(). We can be called
with flag cleared (see begin of ng_source_intr()).
- If NG_SEND_DATA_ONLY() use log(LOG_DEBUG) instead of printf(). Otherwise
we will *flood* console.
- Add ng_connect_t method, which sends NGM_ETHER_GET_IFNAME command
to "output" hook. Cut ng_source_request_output_ifp(). Refactor
ng_source_store_output_ifp() to use ifunit() and don't muck through
interface list.
- Add "setiface" command, which gives ability to configure interface
in case when ng_source_connect() failed. This happens, when we are not
connected directly to ng_ether(4) node.
- Remove KASSERTs, which can never fire.
- Don't check for M_PKTHDR in rcvdata method. netgraph(4) does this
for us.
Style:
- Assign sc_p = NG_NODE_PRIVATE(node) in declaration, to be
consistent with style of other nodes.
- Sort variables.
- u_intXX -> uintXX.
- Dots at ends of comments.

during authentication. Thus we need to call getpwnam *after* the user
has been authenticated. Colin mentioned that we should also move the
check for root in that case.
