2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-15/+15
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)

2007-10-10r23183: Check in a change made by Tridge:Volker Lendecke1-18/+8
This replaces the internal explicit dev/ino file id representation by a "struct file_id". This is necessary as cluster file systems and NFS don't necessarily assign the same device number to the shared file system. With this structure in place we can now easily add different schemes to map a file to a unique 64-bit device node. Jeremy, you might note that I did not change the external interface of smb_share_modes.c. Volker (This used to be commit 9b10dbbd5de8813fc15ebbb6be9b18010ffe8139)

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)

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)

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.

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.

2000-05-10Using 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)
