2012-10-19s3:smbd: move initialization of the smbd_shim from smbd_init_globals() to main()Michael Adam1-16/+0
This is in preparation of adding server exit hooks to the shim. Signed-off-by: Michael Adam <obnox@samba.org>
2012-09-13Sigh :-(. Removing optimization prematurely is the root of all evil :-(.Jeremy Allison1-0/+1
Sorry for the mistake, but the LastDir singleton cache in vfs_ChDir() actually plays an important role. When we're processing a stream of SMB1/SMB2/SMB3 requests we don't want to add a chdir()/getcwd() system call pair on every request if they're all on the same connection and dealing with the same base path. I did some testing with a program that times 1,000,000 chdir() requests vs. 1,000,000 strcmp requests and it's a penalty of 10x doing the system calls. Just because it's old code, doesn't mean it's bad :-(. Autobuild-User(master): Jeremy Allison <jra@samba.org> Autobuild-Date(master): Thu Sep 13 21:31:42 CEST 2012 on sn-devel-104

2012-06-26s3: Restore async i/o with the "native" AIO interfaceVolker Lendecke1-1/+1
eff3609 moved the async signal handler initialization to later in the process to enable aio_fork and aio_pthread on platforms without realtime signals. This commit broke the use of the native aio interface. aio_pending_size is initialized to 0, so aio.c will not allow async i/0 at all if modules do not set that variable correctly. Initialize to 100 right from the start.

2011-10-21s3-seal Remove struct smb_srv_trans_enc_ctxAndrew Bartlett1-2/+2
This structure added no value, particularly after the move to gensec. It was added at a time when auth_ntlmssp_state was not available in the client. This changed a while back (the wrapper was extended with client calls), and the move to gensec again reinforced that we do not need the extra complexity.

2011-06-21s3-build: Provide a run-time shim to work around duplicate symbolsAndrew Bartlett1-0/+16
The become_root() and similar 'smbd' functions that are used widely in Samba libraries had 'dummy' copies in dummysmbd.c and dummyroot.c. These have been replaced by a runtime plugin mechanim, which ensures that standlone binaries still do nothing, while in smbd the correct function is used. This avoids having these as duplicate symbols in the smbd binary, which can cause unpredictable behaviour. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-01-07s3-printing: Initiate pcap reload from parent smbdDavid Disseldorp1-1/+0
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.

This moves those arrays from dynamic to static, shared memory, removing them from globals.c. I did it by dumping the result of init_tables() with dump_data(). Some massage by an editor macro made it the initializer.
