main loop"
This reverts commit 455fccf86b6544cd17a2571c63a88f8aebff3f74.
I'll add a more generic fix for this problem.

Do this by keeping a linked list of delete on close tokens, one for
each filename that identifies a path to the dev/inode. Use the
jenkins hash of the pathname to identify the correct token.

Will be used when we store more than one delete on close token.

to identify a specific path).

This makes us scale better with many simultaneous winbind requests,
some of which might be slow.
This implementation breaks offline logons, as the cached credentials are
maintained in a child (this needs fixing). So, if the offline logons are
active, only allow one DC connection.
Probably the offline logon and the scalable file server cases are
separate enough so that this patch is useful even with the restriction.

Since commit 7022554, smbds share a printcap cache (printer_list.tdb),
therefore ordering of events between smbd processes is important when
updating printcap cache information. Consider the following two process
example:
1) smbd1 receives HUP or printcap cache time expiry
2) smbd1 checks whether pcap needs refresh, it does
3) smbd1 marks pcap as refreshed
4) smbd1 forks child1 to obtain cups printer info
5) smbd2 receives HUP or printcap cache time expiry
6) smbd2 checks whether pcap needs refresh, it does not (due to step 3)
7) smbd2 reloads printer shares prior to child1 completion (stale pcap)
8) child1 completion, pcap cache (printer_list.tdb) is updated by smbd1
9) smbd1 reloads printer shares based on new pcap information
In this case both smbd1 and smbd2 are reliant on the pcap update
performed on child1 completion.
The prior commit "reload shares after pcap cache fill" ensures that
smbd1 only reloads printer shares following pcap update, however smbd2
continues to present shares based on stale pcap data.
This commit addresses the above problem by driving pcap cache and
printer share updates from the parent smbd process.
1) smbd0 (parent) receives a HUP or printcap cache time expiry
2) smbd0 forks child0 to obtain cups printer info
3) child0 completion, pcap cache (printer_list.tdb) is updated by smbd0
4) smbd0 reloads printer shares
5) smbd0 notifies child smbds of pcap update via message_send_all()
6) child smbds read fresh pcap data and reload printer shares
This architecture has the additional advantage that only a single
process (the parent smbd) requests printer information from the printcap
backend.
Use time_mono in housekeeping functions As suggested by Björn Jacke.

Since commit eada8f8a, updates to the cups pcap cache are performed
asynchronously - cups_cache_reload() forks a child process to request
cups printer information and notify the parent smbd on completion.
Currently printer shares are reloaded immediately following the call to
cups_cache_reload(), this occurs prior to smbd receiving new cups pcap
information from the child process. Such behaviour can result in stale
print shares as outlined in bug 7836.
This fix ensures print shares are only reloaded after new pcap data has
been received.

This provides the framework to replace the unexpected.tdb file. Nmbd will
listen on /tmp/.nmbd/unexpected. A client interested in unexpected packets
connects there. It sends a nb_packet_query plus a potential mailslot name for
dgram packets. It waits for a single ack byte to avoid races. After that has
happened, nmbd will pass down all matching packets through that socket.
nb_packet_server_create and nb_packet_dispatch are the nmbd routines,
nb_packet_reader_send/recv and nb_packet_read_send/recv are the client ones.

pass this in as the &now parameter. Push this call inside of
event_add_to_select_args() to the correct point so it doesn't
get called unless needed.

This connects to 445 and after 5 milliseconds also to 139. It treats a netbios
session setup failure as equivalent as a TCP connect failure. So if 139 is
faster but fails the nb session setup, the 445 still has the chance to succeed.

is incorrect.
(I based it on the text in MS-SMB2, silly me :-). Fix it so incoming sequence numbers
can range over the entire allowable bitmap range. This fixes a repeatable
disconnect against Win7.
