their dependency on libc and its versioned symbols. For that to work,
libc needs to be built before any other shared library that might depend
on it. Add necessary glue to make that happen.
for use thoughout the tcp subsystem.
It is IPv4 and IPv6 aware creates a line in the following format:
"TCP: [1.2.3.4]:50332 to [1.2.3.4]:80 tcpflags <RST>"
A "\n" is not included at the end. The caller is supposed to add
further information after the standard tcp log header.
The function returns a NUL terminated string which the caller has
to free(s, M_TCPLOG) after use. All memory allocation is done
with M_NOWAIT and the return value may be NULL in memory shortage
situations.
Either struct in_conninfo || (struct tcphdr && (struct ip || struct
ip6_hdr) have to be supplied.
Due to ip[6].h header inclusion limitations and ordering issues the
struct ip and struct ip6_hdr parameters have to be casted and passed
as void * pointers.
tcp_log_addrs(struct in_conninfo *inc, struct tcphdr *th, void *ip4hdr,
void *ip6hdr)
Usage example:
struct ip *ip;
char *tcplog;
if (tcplog = tcp_log_addrs(NULL, th, (void *)ip, NULL)) {
log(LOG_DEBUG, "%s; %s: Connection attempt to closed port\n",
tcplog, __func__);
free(s, M_TCPLOG);
}
lock and unlock conditionally, not just set the flag on it conditionally.
In practice, this bug couldn't manifest, as in the current revision of
the code, no callers pass a NULL rep.

release documentation from *.TXT files to the RELNOTESng *.sgml
files. I'm pretty sure that, five years later, nobody is wondering
where the original *.TXT files went to in our source tree, so
remove this file to declutter the source tree a bit.
While ng_fec called the ioctl to let interfaces in the bundle know
the list of multicast addresses had changed, it never actually
updated that list on the interfaces in the bundle. Consequently,
the multicast filters could be programmed incorrectly.
if_lagg does this correctly, by maintaining a list of addresses
that it has added to interfaces in the bundle. This commit basically
takes the if_lagg code and adds it to ng_fec.
A version of this patch for RELENG_6 has fixed some problems with
IPv6 ND over ng_fec. This is probably the problem in PR 107523.

function calls are no more generated for vop_lock.
Rename _vop_lock to vop_lock1 to satisfy tools/vnode_if.awk assumption
about vop naming conventions. This restores pre/post-condition calls.
scripts in rc.d to stop rc(8) from booting into multi-user mode when
a critical or severe error condition is encountered.
o Modify scripts in etc/rc.d that already implemented this functionality
independently.
o Document it.
[1] - This subroutine was implemented in FreeBSD in rc.d/fsck. I moved it
to rc.subr(8). Our version differs slightly in that it takes an
optional argument to stop the boot even if "autoboot" is not set.

to use atomics for all counters now. This means sched lock is no longer
responsible for protecting counts in the switch routines.

- Move initialization and asserts into init/fini routines. fini routines
are only needed in the INVARIANTS case for now.

specified in RFC4620. A new flag for icmp6_nodeinfo was added to enable the
feature.
- Also cleaned up the code so that the semantics of the icmp6_nodeinfo
flags is clearer (i.e., defined specific macro names instead of using
hard-coded values).
