2013-05-17lib: Add before/after hooks to async_connectVolker Lendecke1-1/+1
This will facilitiate [un]become_root for smbd to connect safely to ctdbd. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Christian Ambach <ambi@samba.org>
2011-08-29s3-lib: If we create a pipe socket, don't start to listen.Andreas Schneider1-0/+6
The create_pipe_sock() function should only create the socket as the name states and not start to listen on it too. We should start to listen on in the individual places as we need different backlog values.

2011-06-09s3-talloc Change TALLOC_ZERO_P() to talloc_zero()Andrew Bartlett1-4/+4
Using the standard macro makes it easier to move code into common, as TALLOC_ZERO_P isn't standard talloc.

2011-01-07s3: Limit the number of unexpected clients to 200Volker Lendecke1-0/+9
DoS protection like the max winbind clients. Settable by nmbd:unexpected_clients
2011-01-07s3: Limit the number of unexpected packets per client to 10Volker Lendecke1-0/+8
Non-reading clients could maliciously make nmbd allocate memory
2011-01-07s3: Basic infrastructure for /tmp/.nmbd/unexpectedVolker Lendecke1-0/+677
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.

2010-11-14Fix the unexpected.tdb database problem. Change nmbd to store theJeremy Allison1-2/+131
transaction id of packets it was requested to send via a client, and only store replies that match these ids. On the client side change clients to always attempt to ask nmbd first for name_query and node_status calls, and then fall back to doing socket calls if we can't talk to nmbd (either nmbd is not running, or we're not root and cannot open the messaging tdb's). Fix readers of unexpected.tdb to delete packets they've successfully read. This should fix a long standing problem of unexpected.tdb growing out of control in noisy NetBIOS envioronments with lots of bradcasts, yet still allow unprivileged client apps to work mostly as well as they already did (nmblookup for example) in an environment when nmbd isn't running.

2010-10-03s3: Remove talloc_autofree_context() from unexpected.cVolker Lendecke1-2/+1
Same argument as in 997a64f6fb11e19d78c: If tdb_close() was needed at exit time, we'd have more severe problems by now.
2010-09-28s3: Remove talloc_autofree_context() from receive_unexpected()Volker Lendecke1-2/+2
This is freed in this routine a few lines down
2010-09-27Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison1-1/+1
TDB_CLEAR_IF_FIRST tdb's. For tdb's like gencache where we open without CLEAR_IF_FIRST and then with CLEAR_IF_FIRST if corrupt this is still safe to use as if opening an existing tdb the new hash will be ignored - it's only used on creating a new tdb not opening an old one. Jeremy.

2000-02-041) added void* state argument to tdb_traverse. guess what! there wereLuke Leighton1-10/+10
two places i found where it was appropriate to _use_ that third argument, in locking.c and brlock.c! there was a static traverse_function and i removed the static variable, typecast it to a void*, passed it to tdb_traverse and re-cast it back to the traverse_function inside the tdb_traverse function. this makes the use of tdb_traverse() reentrant, which is never going to happen, i know, i just don't like to see statics lying about when there's no need for them. as i had to do in samba-tng, all uses of tdb_traverse modified to take the new void* state argument. 2) disabled rpcclient: referring people to use SAMBA_TNG rpcclient. i don't know how the other samba team members would react if i deleted rpcclient from cvs main. damn, that code's so old, it's unreal. 20 rpcclient commands, instead of about 70 in SAMBA_TNG. (This used to be commit 49d7f0afbc1c5425d53019e234d54ddf205c8e9a)
2000-01-05use a minimal hash size in the unexpected packet database. A largeAndrew Tridgell1-1/+1
hash is only useful when we fetch by key, not when we use tdb_traverse() (This used to be commit e154f041e8ec8b1097d4a0c727c68d217effba34)
2000-01-03added suppport for unexpected udp/138 packetsAndrew Tridgell1-9/+16
I also fixed up the lookup_pdc_name() code so that it now works, even with a NT server that insists on replying to udp/138. The method I used to match packets was to use the mailslot string as a datagram ID. The true dgm_id doesn't work as NT doesn't set it correctly. uggh. PS: Jeremy, I had to change your code quite a bit, are you sure this worked with a Samba PDC?? The code looked broken, it got the offsets wrong in the SMB portion of the packet and filled in the IP incorrectly. (This used to be commit 32f66f4ea63038cb4b3785bdf1762abdde076f5d)
