* s3:includes: change OPLOCK_BREAK_TIMEOUT from 30 to 35 secondsStefan Metzmacher2020-07-081-1/+1
| | | | | | | | | | | | This is what windows is using for normal oplock and lease breaks. Note that windows uses higher values for persistent handles, they use 60 seconds for oplocks and 180 seconds for leases.

| | | | | | | | | | | | This is the s3 debug system, with a number of changes to tidy it up for common use. The debug class system is simplified by the removal of the ISSET table, the system no longer attempts to cope with assignment of DEBUGLEVEL, and the full class table is always available (rather than just DEBUGLEVEL_CLASS[DBCG_ALL]) from startup. It is also no longer confusingly described as a hack, but as the initial table. Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Tue Mar 1 04:32:12 CET 2011 on sn-devel-104
* s3-printing: Initiate pcap reload from parent smbdDavid Disseldorp2011-01-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix bug #7146 - Samba miss-parses authenticated RPC packets.Jeremy Allison2010-02-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parts of the Samba RPC client and server code misinterpret authenticated packets. DCE authenticated packets actually look like this : +--------------------------+ |header | | ... frag_len (packet len)| | ... auth_len | +--------------------------+ | | | Data payload | ... .... | | +--------------------------+ | | | auth_pad_len bytes | +--------------------------+ | | | Auth footer | | auth_pad_len value | +--------------------------+ | | | Auth payload | | (auth_len bytes long) | +--------------------------+ That's right. The pad bytes come *before* the footer specifying how many pad bytes there are. In order to read this you must seek to the end of the packet and subtract the auth_len (in the packet header) and the auth footer length (a known value). The client and server code gets this right (mostly) in 3.0.x -> 3.4.x so long as the pad alignment is on an 8 byte boundary (there are some special cases in the code for this). Tridge discovered there are some (DRS replication) cases where on 64-bit machines where the pad alignment is on a 16-byte boundary. This breaks the existing S3 hand-optimized rpc code. This patch removes all the special cases in client and server code, and allows the pad alignment for generated packets to be specified by changing a constant in include/local.h (this doesn't affect received packets, the new code always handles them correctly whatever pad alignment is used). This patch also works correctly with rpcclient using sign+seal from the 3.4.x and 3.3.x builds (testing with 3.0.x and 3.2.x to follow) so even as a server it should still work with older libsmbclient and winbindd code.
