e91db40c18 Move call to ignore SIGPIPE signals before calling fork(),
so that both parent and child processes ignore this signal.

a856bed399 Ignore SIGPIPE signals on write() failures.
We already check for write() failures and handle EPIPE.
Failure to handle SIGPIPE was resulting in rpc.lockd terminating.

251bb62d63 When a user is in more than 16 groups the call to authunix_create() will
result in abort() beeing called. This is because there is a limit of
the number of groups in the RPC which is 16. When the actual number of
groups is too large it results in xdr_array() returning an error which,
in turn, authunix_create() handles by just calling abort().

Fix this by passing only the first 16 groups to authunix_create().

an initial value to silent compiler.

d32c3b7dce Consumers of nfslockdans() seems to think it should return 0 on success, so
make it so.

75e40e4604 Make this compile cleanly. It passes WARNS=2, but I haven't checked
it is so on more platforms.

eda8b2821f When getting back an NLM DENIED response for a requested lock from the
server, map it to EAGAIN locally rather than EACCES.  The NLM spec
indicates the DENIED corresponds to lock contention, not a permission
failure.  This fixes O_EXLOCK/O_SHLOCK with O_NONBLOCK, which would
previously give a permission error, which in turn fixes things
like mailq(8) and lockf(1) over NFS.

for LOCKD_MSG instead.

32e9a24903 Drop privs while servicing kernel lock requests.
Restore umask used before FIFO creation.
If opening the FIFO fails, exit.
Properly check the return value of open (use == -1 instead of < 0).

64b829d192 leverage fixed fifo implementation (rev 1.56 of
src/sys/fs/fifofs/fifo_vnops.c) to serve locks better, my previous
workaround for lack of decent fifo system wasn't cutting it,
particularly the kernel would send a message down the fifo and
immediately close it, this would lead to delayed unlock requests
being seen by the lockd causing all sorts of badness.

Basically, don't reopen the fifo, just select(2) on it.

5f8568ec81 Fix compiling without -O, some dead code was using non-existant functions,
make the code not automatically dead but actually use the debug level
in order to determine if output is needed.  Fix non-existant from_addr()
by #define'ing it to inet_ntoa().

Remove hardcoded -g from Makefile.
