This is about to be replaced anyway by initialization explicitly
instead of lazily, and reducing the complexity of it. As it is
now, this will work fine, however.
and add a sysctl to pppoe to activate non standard ethertypes
so that idiot ISPs (apparently in France) who use
equipment from idiot suppliers (rumour says 3com)
who use nonstandard ethertypes can still connect.
"yep, sure we do pppoe, we use a different identifier to that dictated in
the standard, but sure it's pppoe!"
sysctl -w net.graph.stupid_isp=1 enables the changeover.
-E Interpret regular expressions followed by -regex and -iregex op-
tions as extended (modern) regular expressions rather than basic
regular expressions (BRE's). The re_format(7) manual page fully
describes both formats.
-iname pattern
Like -name, but the match is case insensitive.
-ipath pattern
Like -path, but the match is case insensitive.
-regex pattern
True if the whole path of the file matches pattern using regular
expression. To match a file named ``./foo/xyzzy'', you can use
the regular expression ``.*/[xyz]*'' or ``.*/foo/.*'', but not
``xyzzy'' or ``/foo/''.
-iregex pattern
Like -regex, but the match is case insensitive.
These are meant to be compatible with other find(1) implementations
such as GNU's or NetBSD's except regexp library differences.

Also, move towards bus space by introducing new macros/inline
functions which make such a move much easier than before.
These inline functions are setup now to work around an IBM EtherJet
pccard cardbus bridge incompatibility. The card works in 8 bit mode,
but not in 16-bit mode when it is connected to a cardbus bridge for
reasons unknown. The Linux driver also has a similar workaround in
it.
Future work will include making the above workaround runtime
conditional rather than compile time conditional, as well as fixing
the interrupts in pccards and converting it to bus space.
for the ICB firmware options meant- *I* had taken it to
mean that if you set it, Node Name would be ignored and
derived from Port Name. Actually, it meant the opposite.
As a consequence- change ICBOPT_USE_PORTNAME to the
define ICBOPT_BOTH_WWNS- makes more sense.
Fix wrong input bitmap for MBOX_DUMP_RAM command. Call
ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD
control command (so outer layers can run a mailbox command
directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so
outer layers can understand response queue entries we
might not know about.
while with threaded software in -CURRENT acting very "weird". It has
seemed, for example, in Mozilla that threads attempting to do host
lookups have been locking up. That's exactly the case.
There was a race condition in the implementation of the initialization
of the mutex used to protect FILE operations, first of all: multiple
instances of FLOCKFILE() in libc could occur on the same FILE at
the same time and cause strange behavior by overwriting eachothers'
creation of the mutex and the rest of the file lock.
Secondly, it's not appropriate to test the "validity" of the file
descriptor referenced by the FILE; if the code is calling FLOCKFILE()
or FUNLOCKFILE(), it wants the FILE to be locked or unlocked, not
to be locked or unlocked on the condition that _file is >= 0. This
also could quite easily cause leaks by failing to perform the lock or
unlock operation when it actually is needed.
Mozilla now works again on -CURRENT when linked to libc_r.so.5 and
libc.so.5.
depend on this. The linux ABI emulator tries to use it for some linux
binaries too. VM86 had a bigger cost than this and it was made default

The changes broken down:
- remove 0 as a wildcard for addresses and port numbers in
src/sys/netinet/in_pcb.c:in_pcbnotify()
- add src/sys/netinet/in_pcb.c:in_pcbnotifyall() used to notify
all sessions with the specific remote address.
- change
- src/sys/netinet/udp_usrreq.c:udp_ctlinput()
- src/sys/netinet/tcp_subr.c:tcp_ctlinput()
to use in_pcbnotifyall() to notify multiple sessions, instead of
using in_pcbnotify() with 0 as src address and as port numbers.
- remove check for src port == 0 in
- src/sys/netinet/tcp_subr.c:tcp_ctlinput()
- src/sys/netinet/udp_usrreq.c:udp_ctlinput()
as they are no longer needed.
- move handling of redirects and host dead from in_pcbnotify() to
udp_ctlinput() and tcp_ctlinput(), so they will call
in_pcbnotifyall() to notify all sessions with the specific
remote address.

the the original trapframe of the syscall, trap, or interrupt that entered
the kernel. Before SMPng, ast's were handled via a psuedo trap at the
end of doerti. With the SMPng commit, ast's were broken out into a
separate ast() function that was called from doreti to match the behavior
of other architectures. Unfortunately, when this was done, the
p_md.md_regs member of curproc was not updateda in ast(), thus when
signals are handled by userret() after an interrupt that returns to
userland, we end up using a stale trapframe that will result in the
registers from the old trapframe overwriting the real trapframe and
smashing all the registers right before we return to usermode. The saved
%cs:%eip from where we were in usermode are saved in the trapframe for
example.
- Don't use an atomic operation to update cnt.v_soft in ast(). This is
the only place the variable is written to, and sched_lock is always
held when it is written, so it is already protected and the mutex release
of sched_lock asserts a memory barrier that ensures the value will be
updated in a timely fashion.
warning on Alphas. It is still not the perfect solution for machines
which sizeof(u_long) != sizeof(void *) but it is as close as we are going
to get for now and consistent with the rest of the code. 8.12 has solved
this problem by providing a portable snprintf() which understands %p.

- Remove unneeded spl()'s around mi_switch() in userret().
- Don't hold sched_lock across addupc_task().
- Remove the MD function child_return() now that the MI function
fork_return() is used instead.
- Use TRAPF_USERMODE() instead of dinking with the trapframe directly to
check for ast's in kernel mode.
- Check astpending(curproc) and resched_wanted() in ast() and return if
neither is true.
- Use astoff() rather than setting the non-existent per-cpu variable
astpending to 0 to clear an ast.
- Don't hold sched_lock around addupc_task() as this apparently breaks
profiling badly due to sched_lock being held across copyin().
