* Avoid undefined behaviour in netgroupcacheSiddhesh Poyarekar2014-01-271-5/+11
| | | | | | Using a buffer after it has been reallocated is undefined behaviour, so get offsets of the triplets in the old buffer before reallocating it.
* Adjust pointers to triplets in netgroup query data (BZ #16474)Siddhesh Poyarekar2014-01-241-1/+11
| | | | | | | | | The _nss_*_getnetgrent_r query populates the netgroup results in the allocated buffer and then sets the result triplet to point to strings in the buffer. This is a problem when the buffer is reallocated since the pointers to the triplet strings are no longer valid. The pointers need to be adjusted so that they now point to strings in the reallocated buffer.
* Don't use alloca in addgetnetgrentX (BZ #16453)Siddhesh Poyarekar2014-01-161-31/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | addgetnetgrentX has a buffer which is grown as per the needs of the requested size either by using alloca or by falling back to malloc if the size is larger than 1K. There are two problems with the alloca bits: firstly, it doesn't really extend the buffer since it does not use the return value of the extend_alloca macro, which is the location of the reallocated buffer. Due to this the buffer does not actually extend itself and hence a subsequent write may overwrite stuff on the stack. The second problem is more subtle - the buffer growth on the stack is discontinuous due to block scope local variables. Combine that with the fact that unlike realloc, extend_alloca does not copy over old content and you have a situation where the buffer just has garbage in the space where it should have had data. This could have been fixed by adding code to copy over old data whenever we call extend_alloca, but it seems unnecessarily complicated. This code is not exactly a performance hotspot (it's called when there is a cache miss, so factors like network lookup or file reads will dominate over memory allocation/reallocation), so this premature optimization is unnecessary. Thanks Brad Hubbard <bhubbard@redhat.com> for his help with debugging the problem.
* nscd: list all tables in usage()Sami Kerola2014-01-041-3/+22
| | | | | | Usage output for option --invalidate=TABLE is not helpful without list of tables. The list is also missing from nscd(8) manual which made it pretty difficult to know what are the tables.
* Fix return code from getent netgroup when the netgroup is not found (bz #16366)Siddhesh Poyarekar2014-01-021-29/+62
| | | | | | | nscd incorrectly returns a success even when the netgroup in question is not found and adds a positive result in the cache. this patch fixes this behaviour by adding a negative lookup entry to cache and returning an error when the netgroup is not found.
* Fix infinite loop in nscd when netgroup is empty (bz #16365)Siddhesh Poyarekar2014-01-021-3/+4
| | | | | | | | | Currently, when a user looks up a netgroup that does not have any members, nscd goes into an infinite loop trying to find members in the group. This is because it does not handle cases when getnetgrent returns an NSS_STATUS_NOTFOUND (which is what it does on empty group). Fixed to handle this in the same way as NSS_STATUS_RETURN, similar to what getgrent does by itself.

* nscd: fix compilation flagsDmitry V. Levin2012-10-021-34/+7
| | | | | | | | | | | | | Commit 61653dfb81b776bb72ce4304175b861d77c357a8 added support for compilers predefining _FORTIFY_SOURCE by adding -U_FORTIFY_SOURCE to CPPFLAGS for these compilers, but that change doesn't work quite well in case of nscd: its Makefile sets _FORTIFY_SOURCE using CFLAGS instead of CPPFLAGS and, thanks to compilation rules defined in Makerules, CPPFLAGS are passed to compiler after CFLAGS, resulting to a build with _FORTIFY_SOURCE turned off. This change implements a more safe method of passing preprocessor and compiler flags so that no nscd modules could be accidentally forgotten.
