2007-10-10r19668: Convert the locking params to use struct share_param instead of snumVolker Lendecke1-1/+1
(This used to be commit 609dbec600048718b86cd1ecdc2ce49bbdeb803c)

2007-10-10r17041: Trying to track down a *big* memory leak in the new lock code.Jeremy Allison1-0/+1
Fix a small one first.... (easy to valgrind). Jeremy (This used to be commit 43d24fbd41ed745a5b21514b526e655663c509ee)
2007-10-10r17000: Allow CIFS POSIX locks to coexist with Windows locks.Jeremy Allison1-1/+1
We shouldn't allow this on the same smbd, but the cifsfs client negotiates POSIX locks then sends Windows ones. Doh ! Can't fix shipped client code.... Jeremy. (This used to be commit 2f8cabe98d3776cb0bdf6b4ef1490fe0119e260a)

2007-10-10r16987: Fix the logic errors in ref-counting Windows locks.Jeremy Allison1-7/+8
Hopefully will fix the build farm. Still a few errors in RAW-LOCK to look at though... Jeremy. (This used to be commit edd72d37de570fdad09f7ee983b5b22a1613e558)

2007-10-10r15018: Merge Volker's ipc/trans2/nttrans changes overJeremy Allison1-16/+75
into 3.0. Also merge the new POSIX lock code - this is not enabled unless -DDEVELOPER is defined. This doesn't yet map onto underlying system POSIX locks. Updates vfs to allow lock queries. Jeremy. (This used to be commit 08e52ead03304ff04229e1bfe544ff40e2564fc7)
2007-10-10r14703: Clarify the return codes for the POSIX locking case. ThisJeremy Allison1-2/+6
was confusing. Jeremy. (This used to be commit bc1a605a39e58a7dbdcd4d132345e957e3ed9d5e)
2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-11/+6
realloc can return NULL in one of two cases - (1) the realloc failed, (2) realloc succeeded but the new size requested was zero, in which case this is identical to a free() call. The error paths dealing with these two cases should be different, but mostly weren't. Secondly the standard idiom for dealing with realloc when you know the new size is non-zero is the following : tmp = realloc(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } However, there were *many* *many* places in Samba where we were using the old (broken) idiom of : p = realloc(p, size) if (!p) { return error; } which will leak the memory pointed to by p on realloc fail. This commit (hopefully) fixes all these cases by moving to a standard idiom of : p = SMB_REALLOC(p, size) if (!p) { return error; } Where if the realloc returns null due to the realloc failing or size == 0 we *guarentee* that the storage pointed to by p has been freed. This allows me to remove a lot of code that was dealing with the standard (more verbose) method that required a tmp pointer. This is almost always what you want. When a realloc fails you never usually want the old memory, you want to free it and get into your error processing asap. For the 11 remaining cases where we really do need to keep the old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR, which can be used as follows : tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the pointer p, even on size == 0 or realloc fail. All this is done by a hidden extra argument to Realloc(), BOOL free_old_on_error which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR macros (and their array counterparts). It remains to be seen what this will do to our Coverity bug count :-). Jeremy. (This used to be commit 1d710d06a214f3f1740e80e0bffd6aab44aac2b0)
2007-10-10r8219: Merge the new open code from HEAD to 3.0. Haven't yet run the tortureJeremy Allison1-17/+21
tests on this as it's very late NY time (just wanted to get this work into the tree). I'll test this over the weekend.... Jerry - in looking at the difference between the two trees there seem to be some printing/ntprinting.c and registry changes we might want to examine to try keep in sync. Jeremy. (This used to be commit c7fe18761e2c753afbffd3a78abff46472a9b8eb)

2003-05-14Prefix VFS API macros with SMB_ for consistency and to avoid problems with ↵Alexander Bokovoy1-5/+5
VFS_ macros at system side. We currently have one clash with AIX and its VFS_LOCK. Compiled and tested -- no new functionality or code, just plain rename of macros for yet-unreleased VFS API version. Needs to be done before a24 is out (This used to be commit c2689ed118b490e49497a76ed6a2251262018769)
2003-05-11Fix VFS layer:Alexander Bokovoy1-6/+5

Add quota support to VFS layer (prepare to NT quota support) Patch by Stefan (metze) Metzemacher, with review of Jelmer and me Tested in past few weeks. Documentation to new VFS API for third-party developers to follow (This used to be commit 91984ef5caa2d13c5d52e1f535bd3bbbae1ec978)

Jeremy. (This used to be commit befbfea21035b0566fc6ba8674587fc44ad7bbdc)
2001-08-12this is a big global fix for the ptr = Realloc(ptr, size) bug.Simo Sorce1-4/+9
many possible mem leaks, and segfaults fixed. someone should port this fix to 2.2 also. (This used to be commit fa8e55b8b465114ce209344965c1ca0333b84db9)
2001-07-02Fixed the nastiest locking bug to track down.... smb_pids are sent in theJeremy Allison1-1/+0

2000-10-06Herb's warning fixes. Also the POSIX locking fix.Jeremy Allison1-1/+1
We now use our own vfs layer to do get/set acl calls (hurrah!). Jeremy. (This used to be commit dfe77c7046cbd65ee52aea7439f21503c1eac41d)
2000-10-06Restructuring of vfs layer to include a "this" pointer - can be an fsp orJeremy Allison1-6/+6
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.

2000-05-25Fixed misunderstanding found during CIFS conference. Overlapping lockJeremy Allison1-340/+278
ranges (not just included lock ranges) should be handled correctly. UNIT test still needed. Jeremy. (This used to be commit 07872298e3ee8b4b50b69cb4e49b88635792128e)
2000-05-10Using a structure for a tdb key can lead to insideous, hardHerb Lewis1-0/+2
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)
2000-05-05Two fixes. Added missong logic & case in lock split code.Jeremy Allison1-4/+12
Fixed range split into two, as DLIST_ADD has the wrong semantics... Jeremy. (This used to be commit 82681edda14dcc3d58bb303cfac5452072de67df)
2000-05-04Updated to fix overlapping problem.Jeremy Allison1-68/+142

Jeremy. (This used to be commit 57bf92d90147b207664152d44ce4bfb5235dc7d8)
2000-05-03Fixed the bug locktest.c found, it was an off-by-one error in the non-overlapJeremy Allison1-1/+1

2000-05-03Fixed silly bug where I wasn't checking for matching fd's in closing a file.Jeremy Allison1-7/+24
This caused smbd crashes on SIGKILL. Jeremy. (This used to be commit d4dcefd12d14df112f083c312acbea0196bc5c23)
2000-05-03Added range info to the panic message to track down the bug withJeremy Allison1-1/+5
locktest. Jeremy. (This used to be commit 91f038356b7efa04cf4bfa5e6afd8b144b6b4ad5)
2000-05-03Fix for stacking locks in brlock and POSIX. Windows only allows a read lockJeremy Allison1-91/+129
to overlay a write lock on the same fnum. When overlaying read locks onto a write lock, the number of locks is counted, and the first unlock removes the write lock and downgrades this to a read lock. Do the same when mapping to POSIX. Jeremy. (This used to be commit 74d42644e6e52808037975e909aa56c850838b76)
2000-05-02Implemented the last (I hope:-) part of the locking puzzle, the referenceJeremy Allison1-23/+90
counting when Windows downgrades a write lock to a read lock, then reference counts the unlocks to match the locks. With this code the POSIX unlock isn't done until the final Windows unlock. Jeremy. (This used to be commit 6eb4fb6eef367f68169d6ec1c816226b1ad9f110)
2000-05-02split the username in the vuser structure into a separateAndrew Tridgell1-1/+2
userdom_struct. As the name implies this also contains a domain (unused at the moment). This will be important shortly, as operation in appliance mode needs the domain to be always carried with the username. (This used to be commit ee8546342d5be90e730372b985710d764564b124)
2000-05-02Moved uglyness needed in fcntl locking (64->32 bit mapping, NFSJeremy Allison1-3/+121
errors etc.) into locking/posix.c, where it is needed. fcntl_lock in lib/util.c is now very small and clean. Added (*lock) op to vfs layer. Jeremy. (This used to be commit 46092ee1410faa4e3c143d80a960a8adaa19d7fc)
