2001-11-30After conversations with Andrew, improved the robustness of theJeremy Allison1-26/+53
sharemode db in the following way. Originally, on startup and shutdown, smbd would scan the share mode db to ensure it was correct. This lead to scalability issues as scans lock the db for quite a long time. Andrew had the brainstorm that we only care about the record we're about to read. This new code (small change really, but quite significant) causes get_share_modes() to do a process_exists() call against each pid in each record, and to delete any that don't and re-write the entry if any dead records were detected. This allowed me to remove the startup/shutdown scans of the db (they can be added into smbstatus if anyone really cares to have them back). This will please the vfs author who was worried about the time taken on open() calls, and will lead to much greater robustness and scalability in the share mode db. We need much testing of this, and also netbench tests to ensure the extra process_exists() calls don't hurt performance (they shouldn't it's a very simple system call). Jeremy.

2001-09-18Correct fix for unaligned memcpy - malloc'ed memory incremented by ↵Jeremy Allison1-18/+20
sizeof(struct locking_data) was not forced to be 8 byte aligned. Use union to force it to be correctly aligned for memcpy and use void *, to tell compiler not to optimize aligned copy (this last fix suggested by Trond @ RedHat). The first fix should be sufficient, but this provides a "belt and braces" fix. Jeremy. (This used to be commit 22c5915bb466529ac1bcb5c2574888b360a9775b)

2001-09-052nd DELETE_ON_CLOSE_FLAG fix ...Andrew Tridgell1-3/+3
we set the DELETE_ON_CLOSE_FLAG on all share modes on the file, which means the share mode in the fsp will not match the one in the tdb when we come to close for other file handles, which means we end up with share modes on files after all handles are closed fixed by making the comparison function that says if two shares modes are equal ignore the DELETE_ON_CLOSE_FLAG (This used to be commit 7b39c4c59897669106d7129bad8af3d592d25838)

to make it type incompatible with BOOL so we catch errors sooner. This has already found a number of bugs (This used to be commit 1b778bc7d22efff3f90dc450eb12baa1241cf68f)
2001-08-27converted smbd to use NTSTATUS by defaultAndrew Tridgell2-33/+73
major changes include: - added NSTATUS type - added automatic mapping between dos and nt error codes - changed all ERROR() calls to ERROR_DOS() and many to ERROR_NT() these calls auto-translate to the client error code system - got rid of the cached error code and the writebmpx code We eventually will need to also: - get rid of BOOL, so we don't lose error info - replace all ERROR_DOS() calls with ERROR_NT() calls but that is too much for one night (This used to be commit 83d9896c1ea8be796192b51a4678c2a3b87f7518)

2001-08-21This is Jeremy pretending to be Volker, 'cos theVolker Lendecke1-64/+136
link from Seattle is having problems. I've added 3 things here to work on the fcntl spin problem. 1). Check *all* tdb return codes... :-). 2). If we're asking ourselves to break an oplock, and we can't find a fsp pointer that matches the entry, this is a *logic bug* and we should abort and panic so someone with gdb can pick up the pieces. 3). After we've broken an oplock, ensure that the entry itself has been removed, and if not remove it ourselves. This should not be neccessary in a correctly working environmen,t, but will provide an added layer of robustness in error situations. 4). I hate german keyboards :-) :-). Jeremy.

we're comparing structures (ie. don't just do a memcmp). I don't think this will fix the fcntl spin issue, but it's a "just in case" change. Jeremy. (This used to be commit 41066208ad8ca20d35a32bdf9ad934e11465c8f1)

2001-03-30This is a big, rather ugly patch. Whilst investigating the files not truncatedJeremy Allison1-32/+39
when copying to a full disk problem, I discovered that we were not allowing the delete on close flag to be set properly, this led to other things, and after investigation of the proper delete on close semantics and their relationship to the file_share_delete flag I discovered there were some cases where we weren't doing the deny modes properly. And this after only 5 years working on them..... :-) :-). So here's the latest attempt. I realised the delete on close flag needs to be set across all smbds with a dev/ino pair open - in addition, the delete on close flag, allow share delete and delete access requested all need to be stored in the share mode tdb. The "delete_on_close" entry in the fsp struct is now redundant and should really be removed. This may also mean we can get rid of the "iterate_fsp" calls that I didn't like adding in the first place. Whilst doing this patch, I also discovered we needed to do the se_map_generic() call for file opens and POSIX ACL mapping, so I added that also. This code, although ugly, now passes the deny mode torture tests plus the delete on close tests I added. I do need to add one more multiple connection delete on close test to make sure I got the semantics exactly right, plus we should also (as Andrew suggested) move to random testing here. The good news is that NT should now correctly delete the file on disk full error when copying to a disk :-). Jeremy. (This used to be commit 51987684bd231c744da2e5f3705fd236d5616173)

a --with-spinlocks option to configure, this does mean the on-disk tdb format has changed, so 2.2alphaX sites will need to re-create their tdb's.

a conn struct depending on the call. We need this to have a clean NT ACL call interface. This will break any existing VFS libraries (that's why this is pre-release code). Andrew gets credit for this one :-) :-). In addition - added Herb's WITH_PROFILE changes - Herb - please examine the changes I've made to the smbd/reply.c code you added. The original code was very ugly and I have replaced it with a START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor. Please check this compiles ok with the --with-profile switch. Jeremy.

The motivation for this system is to replace the UDP message for oplocks, but this commit only does the "set debug level" message. (This used to be commit 2a34ee95f3929cff131db6c5a2b4820194c05b2d)

2000-05-10Using a structure for a tdb key can lead to insideous, hardHerb Lewis3-20/+25
to find bugs. On 64 bit IRIX, structure packing means that a struct { SMB_DEV_T dev /* 4 bytes */ SMB_INO_T ino /* 8 bytes */ } has 4 bytes of padding between the two members. If you don't null the memory before using it as a tdb key, you randomly can't find keys depending on what is in the padding. This caused me immense pain and was hard to track down.... :-) Jeremy. (This used to be commit f2a5ba3f0939f59097f0ef6a25f1cf9b5574f157)
