2011-02-02Based on a conversation with Volker, refactor some of the oplock code to ↵Jeremy Allison1-71/+160
make it comprehensible. delay_for_oplocks() did 4 things. 1). Validation of existing oplock types. 2). Check for compatibility with batch oplocks (pass 1). 3). Check for compatibility with exclusive oplocks (pass 2). 4). Set the correct oplock type from the requested value. Refactor into 4 separate functions: 1). find_oplock_types() - does validation of oplock types and returns pointers to specific values. 2). delay_for_batch_oplocks() - the pass 1 phase above. 3). delay_for_exclusive_oplocks() - the pass 2 phase above 4). grant_fsp_oplock_type() - Set the correct oplock type from the requested value. Now separated out this code should be much easier to understand and modify. This also fixes an erroneous SMB_ASSERT which was hidden by the previous complexity of the single delay_for_oplocks() code.

copy_file(): - Firstly, if the source file is zero bytes, NT_STATUS_DISK_FULL is returned. - Secondly, the conditional lseek is confusing.

2011-01-21s3: Fix a deadlock between smbd and ctdbdVolker Lendecke1-4/+18
Do the notification after we released the share mode lock. Inside notify_fname we take out another tdb lock. With ctdb also accessing our databases, this can lead to deadlocks. Putting this notify after the TALLOC_FREE(lck) above we avoid locking two records simultaneously. Notifies are async and informational only, so calling the notify_fname without holding the share mode lock should not do any harm.

2011-01-07s3-printing: Initiate pcap reload from parent smbdDavid Disseldorp5-40/+65
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 Disseldorp3-7/+12
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.

2010-12-18Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison1-9/+12
vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.
