2014-04-30Consolidate code to initialize nscd dataset headerSiddhesh Poyarekar
This patch consolidates the code to initialize the header of a dataset into a single set of functions (one for positive and another for negative datasets) primarily to reduce repetition of code. The secondary reason is to simplify Patch 2/2 which fixes the problem of an uninitialized byte in the header by initializing an unused field in the structure and hence preventing a possible data leak into the cache file.

2009-10-29Fix a few asserts and IO calls in nscd.Anders Johansson
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 Drepper
This reverts commit 137028b4d7e50f71906c1656c27079eac5a1d085. Conflicts: ChangeLog
2009-07-16Fix lock handling in memory hander of nscd.Petr Baudis
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.
2009-02-13[BZ #5381]Ulrich Drepper
2009-02-13 Ulrich Drepper <drepper@redhat.com> [BZ #5381] * nscd/nscd.h: Remove definitions and declarations for mem_in_flight. Change mempool_alloc prototype. * nscd/mem.c (gc): Don't handle mem_in_flight. (mempool_alloc): Third parameter now only indicates whether this is the first call (to allocate data) or not. If it is, get db rdlock. Release it on error. Don't handle mem_in_flight. * nscd/aicache.c (addhstaiX): Mark he parameter as const. Adjust third parameter of mempool_alloc calls. Nothing to do here in case mempool_alloc fails. Avoid local variable shadowing parameter. No need to get db rdlock before calling cache_add. * nscd/cache.c (cache_add): Adjust call to mempool_alloc. There is no mem_in_flight array anymore. * nscd/connections.c: Remove definition and handling of mem_in_flight. * nscd/grpcache.c (cache_addgr): Adjust third parameter of mempool_alloc calls. Mark he parameter as const. Nothing to do here in case mempool_alloc fails. No need to get db rdlock before calling cache_add. * nscd/hstcache.c (cache_addhst): Likewise. * nscd/initgrcache.c (addinitgroupsX): Likewise. * nscd/servicescache.c (cache_addserv): Likewise. * nscd/pwdcache.c (cache_addpw): Likewise.

Afterwards compute wakeup time with current wakeup_time value in mind.
