According to susv4 sendmsg, NOSIGAL is effective for stream-oriented sockets.
Datagram sockets won't send SIGPIPE anyway. Looking at Linux kernel sources,
this is only looked at in stream functions. I guess this is a left-over from my
tmsgd attempts, which was based on stream sockets. messaging_dgm still only
uses datagram sockets, so MSG_NOSIGNAL is not needed here.

If locking.tdb contains invalid records, "get_file_infos" called from directory
enumeration crashes in Samba 4.4. The reason is that if "dbwrap_watched_parse"
returns -1 due to record corruption, dbwrap_watched_parse_record returns
NT_STATUS_OK without having called the parse function. Before 66cba9939b
this led to "lck->data" to be uninitialized data, so smbd 4.4 would crash in
this case. After 66cba9939b we implicitly initialize "state.lck" to NULL,
so we don't have this particular problem anymore
Apply the fix in master too, returning NT_STATUS_OK from parse_record without
having called the parser could lead to bugs in other cases too.

"Since kernel 2.6.19, Linux supports an alternate syntax for the
/proc/sys/kernel/core_pattern file. If the first character of this

as a user-space program to be executed."
Discarding this symbol would result in misleading logs for smbd/nmbd/winbindd.
For example even if core_pattern contains '|', smbd logs would suggest the
following:
...
dumping core in /var/log/samba/cores/smbd

Yes, there is one.... I've seen two flaky builds on sn-devel with
pthreadpool after the coverity checks went in. They were in the
ret = pthread_mutex_unlock(&pool->mutex);
assert(ret == 0);
in pthreadpool_parent() and pthreadpool_child(). No idea what that was,
I could not really reproduce that. A build attempt on FreeBSD also gave
an erratic error, this time it was an EINVAL in
ret = pthread_mutex_lock(&pool->mutex);
assert(ret == 0);
pthreadpool_parent(). EINVAL means that the mutex is not a proper
mutex. What happened: Someone (a detached thread) does the
pthreadpool_free behind our back, while we are in pthreadpool_parent,
preparing the fork. Unfortunately the mutex was already destroyed before
we came to lock it.
The fix is simple: Remove the obsolete struct pthreadpool from the
linked list before the mutex is destroyed.

Previously, we only created a send queue for a peer if the initial send
to the non-blocking non-connected socket reported EWOULDBOCK (because
the channel was full).
With this change, we now always create a send queue and use a connected,
non-blocking datagram socket from the beginning.
Initially, the socket of the send queue is set to non-blocking mode and
we attempt a direct send via sendmsg(). If that returns EWOULDBOCK, we
set the send queue to blocking mode and let the threadpool handle the
IO.
When a send queue becomes empty, we set the send queue socket back to
non-blocking.

This introduces caching of unix datagram send queues. Right now send
queues are only created for peers if the channel to the peer is full and
a send reported EWOULDBLOCK.
At this stage, performance will actually be slightly worse, because now
if there's a cached queue for a peer without queued messages, we don't
attempt direct send anymore until the send queue is removed from the
cache.
The next commit will modify unix_msg to always create a send queue with
the datagram socket in connected mode and again attempt an non-blocking
send on the connected socket first. Then only if that returns
EWOULDBLOCK, the send has to go through the threadpool.

Trying to trim down messages.c a bit: Sending to all processes that are
registered in serverid.tdb and filtering to me is not really logic of general
messaging but more of the serverid code.

The existing one with a separate dbwrap_watchers.tdb turns out to
create a performance penalty in a clustered environment. Non-clustered,
dbwrap_parse_record on non-existent records is very cheap, but in a
cluster environment this is very noticable.
This implementation puts the watcher information into the records itself. For
large records, this might be another performance penalty, because we have to
assemble the final record together with talloc and memcpy, but this might be
fixed later with a tdb_storev call.

are rather small, but offset calculations without overflow checks are bad.

Typicall, when we watch a record, we wait for a process to give up some
resource. Be it an oplock, a share mode or the g_lock. If everything goes well,
the blocker sends us a message. If the blocker dies hard, we want to also be
informed immediately.

This is the last step to fix a regression introduced by
3fe3226daa and
3fe3226daa8488e0fa787c40359c3401b6f05fc0^
where we pass the ctdb-messaging object conn to db_open() and add a
reference to it to the private db_ctdb_ctx for later use. Unfortunately
reinit_after_fork() destroys conn, leaving us with an invalid reference.
The previous patches added new lower level functions
messaging_ctdbd_reinit() and ctdbd_reinit_connection(), finally use them
them from messaging_reinit(). They preserve the conn object and simply
reinitialize the IPC fd.

Split out and internal function from messaging_ctdbd_init() that does
the connection setup. Keep the conn object allocation in
messaging_ctdbd_init().
This is in preperation of adding messaging_ctdbd_reinit() which will use
the new internal function as well.
messaging_ctdbd_init_internal() has a new reinit flag,
messaging_ctdbd_init() calls with reinit=false resulting in unmodified
behaviour.

The sysquotas module has several supported backends for
getting/setting user/group quota. This patch removes a check
by the common code, to see if the backend has returned EDQUOT.
Before this patch, it was OK for a backend to return with error
and errno set to EDQUOT, and that meant success, but with a warning
that the user/group is over quota. This is the system behavior on
some Unices. This patch removes this from the protocol between the
sysquota module and its backend drivers - it's the responsibility
of the backend to return 0 iff it has fulfilled the request to get or
set quota.
