2011-10-31Cache network interface informationUlrich Drepper4-7/+162
Whenever getaddrinfo needed network interface information it used the netlink interface to read the information every single time. The problem is that this information can change at any time. The patch implements monitoring of the network interfaces through nscd. If no change is detected the previously read information can be reused (which is the norm). This timestamp information is also made available to other processes using the shared memory segment between nscd and those processes.

2011-07-11Generalize framework to register monitoring of files in nscdUlrich Drepper4-104/+144
nscd can clear caches when certain files change. The list of files was hardcoded so far and worked for nss_files and nss_dns and those modules which need no monitoring. nss_db, for instance, has its own set of files to monitor. Now the NSS modules themselves can request that certain files are monitored.

Cleanup and optimize last patch. Add timeout fixes also to the services cache.

2011-06-29Avoid write to invalid file descriptor in nscdUlrich Drepper2-4/+6
When readding entries to the group and services cache and the lookup is unsuccesful, we tried to write the notfound record. Just don't do it in this case.

2009-10-29Fix a few asserts and IO calls in nscd.Anders Johansson5-13/+13
The nscd/*cache.c files contain assert()s, writeall() and sendfileall() calls that invalidly use together &dataset->resp and total where either dataset or dataset->head.recsize should be used instead one of the components. In the writeall() and sendfileall() cases, it is unlikely to matter in practice, but the assertions can fail sometimes without a proper reason.

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.
