* Fix incorrect backtrace unwinding through thread_start() on x86_64 pasky/fixes-overdueJan Kratochvil2010-11-162-4/+6
| | | | | Provide CFI for the outermost clone() to ensure proper unwinding stop of gdb.
* Allow aux_cache_file open()ing to fail silently even in the chroot mode.Petr Baudis2010-11-162-8/+10
| | | | | | | | | The aux_cache fix of bug 11149 introduced a new bug - normally, ldconfig -r never cares if the auxiliary cache is not available and that is not a fatal problem, however this is not the case in case of ldconfig -r when executed as non-root. In that case, ldconfig -r fails hard unless var/cache/ldconfig/ exists within the chroot. This patch fixes that.
* Make nscd load /etc/host.conf options in aicachePetr Baudis2010-11-163-0/+11
| | | | | | | | | | This patch makes sure _res_hconf is initialized before resolving is being done. However, this would not be enough since nscd has its own _res_hconf due to nscd/res_hconf.c; _res_hconf_init() would work on different _res_hconf instance than the NSS routines. We just need to make sure nscd and glibc share the same _res_hconf instance - this should not be a problem since users should run matching versions of glibc and nscd anyway.
* Fix multiple nss_compat initgroups() bugsPetr Baudis2010-11-162-8/+17
| | | | | | | | | | | | Compat initgroups() is completely broken; the code will always set skip_initgroups_dyn to true, so initgroups() will never be actually called, but due to the nature of the code, setgrent() won't be called either - thus, subsequent invocations of initgroups() will not return the NIS group list anymore. This is a simple patch that makes sure skip_initgroups_dyn is set only in case initgroups is not available; it also attempts to handle the unavailability of other NSS interfaces better.
* Add proper unwind information for x86_64 _finiMichael Matz2010-11-162-1/+37
| | | | | | | | It is impossible to reliably unwind the stack above _fini() on x86_64 since no unwind information is provided for it and it modifies a stack register. This matters for gdb backtracing - if a process crashes within a destructor, it can frequently be essential to look at why the program began terminating in the first place.
* Fix jn() precision problems around zero points of j0()Petr Baudis2010-11-166-5/+60
| | | | | | | | | | | | | | | | | | | | | There appears to be a really nasty bug in jn() from fdlibm, which is the foundation for most libm implementations (including glibc libm). The zeroth-order j0() and first-order j1() cylindrical Bessel functions are used to recursively generate the jn() value, but only the zeroth-order Bessel function is used to normalize it; however, each of the functions gets highly imprecise (approaching "bogus") near its zero point, making the jn() value itself bogus. But in fact, the zero points of j0() and j1() never coincide, thus j1() should be used in case it is more precise than j0(). (That is, simply when its value is further from zero.) As an example, 2.4048255576957729_8 is the first zero of j0(). The proper value as calculated by Mathematica is 0.19899990535769... However, jn() returns -inf on 64-bit arch, or 0.185007 on 32-bit arch. With the proposed patch below, the returned value is 0.199000. The fix is based on work by Steve Kargl and Tobias Burnus.
* nscd/hstcache.c: Propagate TRY_AGAIN properly to the clients.Jan Sembera2010-11-162-6/+31
| | | | | When nscd host cache gets temporary error from nss, it should return temporary error instead of permanent error to the application.

* 32bit memset-sse2.S fails with uneven cache sizeUlrich Drepper2010-11-054-4/+43
| | | | | | | | | 32bit memset-sse2.S assumes cache size is multiple of 128 bytes. If it isn't true, memset-sse2.S will fail. For example, a processor can have 24576 KB L3 cache and 20 cores. That is 2516582 byte per core. Half of it is 1258291, which isn't helpful for vector instructions. This patch rounds cache sizes to multiple of 256 bytes and adds "raw" cache sizes.
