2013-07-22tdb: Fix CID 1034959 Uninitialized scalar variableVolker Lendecke1-1/+1
log_ctx.log_private was used uninitialized. Not a real bug here, as tdb_log does not access it, but tdb_open_ex still moves around uninitialized data. So this would show up in valgrind as well. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

2013-07-17Fix bug 10025 - Lack of Sanity Checking in calls to malloc()/calloc().Bill Parker2-0/+13
In reviewing various files in Samba-4.0.7, I found a number of instances where malloc()/calloc() were called without the checking the return value for a value of NULL, which would indicate failure. (NB. The changes needed to ccan, iniparser, popt and heimdal will be reported upstream, not patched inside Samba).

2013-02-19tdb: Enhance lock tracking a bitVolker Lendecke1-0/+11
lock-tracking.c mirrors the in-kernel fcntl structures to detect unexpected use of fcntl calls. During my mutex work I changed our fcntl use so that we unlock the allrecord_lock in two pieces: The range covering the hash locks and the range covering the data area for the individual traverse record locks. Splitting locks is not covered by lock-tracking.c. This patch extends lock-tracking.c with this little piece. It's still far from complete to track the full range of fcntl semantics. It is not strictly needed right now, but it does not hurt either. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
