2012-10-06tdb: Make tdb robust against improper CLEAR_IF_FIRST restartVolker Lendecke1-4/+28
When winbind is restarted, there is a potential crash in tdb. Following situation: We are in a cluster with ctdb. A winbind child hangs in a request to the DC. Cluster monitoring decides the node has a problem. Cluster monitoring decides to kill ctdbd. winbind child still hangs in a RPC request. winbind parent figures that ctdb is dead and immediately commits suicide. winbind parent is restarted by cluster management, overwriting gencache.tdb with CLEAR_IF_FIRST. The CLEAR_IF_FIRST logic as implemented now will not see that a child still has the tdb open, only the parent holds the ACTIVE_LOCK due to performance reasons. During the CLEAR_IF_FIRST logic is done, there is a very small window where we ftruncate(tfd, 0) the file and re-write a proper header without a lock. When during this small window the winbind child comes back, wanting to store something into gencache.tdb, that winbind child will crash with a SIGBUS. Sounds unlikely?

2012-10-06tdb: Make robust against shrinking tdbsRusty Russell1-12/+20
When probing for a size change (eg. just before tdb_expand, tdb_check, tdb_rescue) we call tdb_oob(tdb, tdb->map_size, 1, 1). Unfortunately this does nothing if the tdb has actually shrunk, which as Volker demonstrated, can actually happen if a "longlived" parent crashes. So move the map/update size/remap before the limit check. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-10-05talloc: Convert error cecking macros into fnsSimo Sorce1-37/+74
This will avoid 'surprise returns' and makes the code cleare to readers. These macros were complex enough to warrant a full function anyway not just for readability but also for debuggability.

2012-10-05Add memory limiting capability to tallocSimo Sorce5-40/+327
By calling talloc_set_memlimit() we can now set a max memory limit for a whole talloc hierarchy. ANy attempt to allocate memory beyond the max allowed for the whole hierarchy wil cause an allocation failure. Stealing memory correctly accounts for used memory in the old and the new hierarchy but exceeding the memory limit in the new parent will not cause a failure.

This is normally handled by the waf core, but for HP-UX we currently fail. The autoconf code hard-codes a case for HP-UX, but I want to try testing it using a generic system first. Andrew Bartlett

2012-09-23lib/replace: Try to fix build on HP-UX for os2_delete testAndrew Bartlett4-17/+6
The issue is that this file is both used in an autoconf test, and later in a smbtorture test. Because os2_delete.c does not include replace.h, bool may not be defined. So, instead we shift the need for bool to a different header. (The readdir tests in repdir.m4 are not yet in the waf configure). Andrew Bartlett
