e8156439f2 r23183: Check in a change made by Tridge:
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.

894358a8f3 r13915: Fixed a very interesting class of realloc() bugs found by Coverity.
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 :-).

636f146abf Restructuring of vfs layer to include a "this" pointer - can be an fsp or
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.

e522de4808 Using a structure for a tdb key can lead to insideous, hard
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.... :-)
