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.

2010-12-17s3:smbd: implement FSCTL_SET_SPARSE more correctlyBjörn Jacke1-5/+43
this is a port of a patch from metze for 3.3: We don't do the "strict allocation" when the sparse bit isn't set, but that shouldn't matter. We now allow windows applications to set and unset the sparse bit. Note that in order to implement this 100% like described in [MS-FSA], we'd have to change our data model and support the sparse flag per stream.

2010-12-10s3-smbd Don't send SPNEGO principal (rfc4178 hint) by defaultAndrew Bartlett1-0/+3
This patch, based on the suggestion by Goldberg, Neil R. <ngoldber@mitre.org> turns off the sending of the principal in the negprot by default, matching Windows 2008 behaviour. This slowly works us back from this hack, which from an RFC perspective was never the right thing to do in the first place, but we traditionally follow windows behaviour. It also discourages client implmentations from relying on it, as if they do they are more open to man-in-the-middle attacks. Andrew Bartlett
