2009-07-17Revert "Fix lock handling in memory hander of nscd."Ulrich Drepper7-5/+27
This reverts commit 137028b4d7e50f71906c1656c27079eac5a1d085. Conflicts: ChangeLog
2009-07-16Fix lock handling in memory hander of nscd.Petr Baudis7-27/+5
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the corresponding pthread_mutex_unlock() calls. Also, the database lock is never unlocked in one branch of the mempool_alloc() if. I think unreproducible random assert(dh->usable) crashes in prune_cache() were caused by this. But an easy way to make nscd threads hang with the broken locking was.
2009-07-16Use correct release semantic in list update.Andreas Schwab1-1/+1
nscd uses lockfree lists and we need to ensure the correct release semantics is used when adding to the list.
2009-06-16Consolidate PIE linking Makefile rules.H.J. Lu1-9/+2
2009-05-18Fix forced loop termination in nscd database lookup.Jakub Jelinek1-3/+13
There are two issues with the forced loop exit in the nscd lookup: 1. the estimate of the entry size isn't pessimistic enough for all databases, resulting potentially is too early exits 2. the combination of 64-bit process and 32-bit nscd would lead to rejecting valid records in the database.
2009-05-16Move BLOCK_ALIGN* macros back.Ulrich Drepper2-5/+5
The move to nscd-client.h was only needed for some interim version of the patch. The final version doesn't need it. Undo the change.
2009-05-16Fix exit condition.Ulrich Drepper1-1/+1
The patch to bound the search in the nscd caches used a wrong exit condition. Fixed now.
2009-05-15Further robustify nscd database lookup.Ulrich Drepper3-7/+8
We can compute an absolute maximum for the number of elements which can fit into the currently mapped database. Stop after that many iterations.
2009-05-15Robustify libc-side nscd database reader.Jakub Jelinek8-22/+41
The nscd database mapped in processes can change at any time. We have to be more vigilant when it comes to using that memory. Test the data entries are valid in their entire size, don't read data again from memory once we verified it, and make sure the trailing pointer is not going off the deep end.
2009-05-15Don't try to cleanup libselinux and libaudit.Jakub Jelinek3-20/+2
Because we are not shutting down the other threads first another thread might work on a query before the process shuts down. In this case the now uninitialized libselinux and libaudit might be used. Just don't free the resources. It's not necessary anyway because the process is about to terminate.
