2011-02-22s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_infoAndrew Bartlett1-3/+3
These variables, of type struct auth_serversupplied_info were poorly named when added into 2001, and in good consistant practice, this has extended all over the codebase in the years since. The structure is also not ideal for it's current purpose. Originally intended to convey the results of the authentication modules, it really describes all the essential attributes of a session. This rename will reduce the volume of a future patch to replaced these with a struct auth_session_info, with auth_serversupplied_info confined to the lower levels of the auth subsystem, and then eliminated. (The new structure will be the output of create_local_token(), and the change in struct definition will ensure that this is always run, populating local groups and privileges).

2011-01-07s3-printing: Initiate pcap reload from parent smbdDavid Disseldorp1-36/+9
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.
2011-01-07s3-printing: reload shares after pcap cache fillDavid Disseldorp1-1/+2
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.

2010-10-07s3: Fix the async echo responder for netbios keepalivesVolker Lendecke1-10/+23
This fixes a crash in the echo responder when the client started to send the NetBIOS-Level 0x85-style keepalive packets. We did not correctly check the packet length, so the code writing the signing seqnum overwrote memory after the malloc'ed area for the 4 byte keepalive packet.

2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-19/+16
Previously, only one fd handler was being called per main message loop in all smbd child processes. In the case where multiple fds are available for reading the fd corresponding to the event closest to the beginning of the event list would be run. Obviously this is arbitrary and could cause unfairness. Usually, the first event fd is the network socket, meaning heavy load of client requests can starve out other fd events such as oplock or notify upcalls from the kernel. In this patch, I have changed the behavior of run_events() to unset any fd that it has already called a handler function, as well as decrement the number of fds that were returned from select(). This allows the caller of run_events() to iterate it, until all available fds have been handled. I then changed the main loop in smbd child processes to iterate run_events(). This way, all available fds are handled on each wake of select, while still checking for timed or signalled events between each handler function call. I also added an explicit check for EINTR from select(), which previously was masked by the fact that run_events() would handle any signal event before the return code was checked. This required a signature change to run_events() but all other callers should have no change in their behavior. I also fixed a bug in run_events() where it could be called with a selrtn value of -1, doing unecessary looping through the fd_event list when no fds were available. Also, remove the temporary echo handler hack, as all fds should be treated fairly now.

2010-09-28s3: Attempt to fix bug 7518Volker Lendecke1-6/+6
If select returns -1, we can't rely on the fd sets. The current code might loop endlessly because when putting an invalid fd (the closed socket?) on the read set, a select implementation might choose not to touch it but directly return with EINVAL. Thus run_events will see the socket readable, which leads to a "return true", and thus a NT_STATUS_RETRY -> same game again. We should never get into this situation, but to me the logfiles given in bug 7518 do not reveal enough information to understand how this can happen.

Found by the CodeNomicon test suites at the SNIA plugfest. http://www.codenomicon.com/ If an invalid NetBIOS session request is received the code in name_len() in libsmb/nmblib.c can hit an assert. Re-write name_len() and name_extract() to use "buf/len" pairs and always limit reads. Jeremy.
