2011-01-11syslog: fix 'everyone logs with user facility'Roman I Khimov
It's been found that on uclibc-based system most of the programs log with 'user' facility despite the calls to openlog() with other facilities explicitly set. Most but not all. Investigating that I've found that the ones logging with proper facilities used LOG_NDELAY in openlog(). The problem is that LogFacility is overwritten in openlog_intern and LOG_USER is passed to it from vsyslog() no matter what the program set with openlog().

2010-11-28libc_utmp: Fix getutmp and getutmpx for x86_64Carmelo Amoroso
On x86_64, when WORDSIZE_COMPAT32 is enabled, the ut_tv field of 'struct utmp' and 'struct utmpx' are defined as two nested structs instead of being defined as 'struct timeval', so it is not possible to directly assign the two ut_tv values. This patch split the assignment by setting each fields (tv_sec, tv_usec) of the ut_tv filed separately It is als compatible with 'struct timeval' usage.

2010-10-27mips: fix errno setting after syscallAlexander Gordeev
If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

Don't try to be smart by dynamically realloc buffersize as it doesn't work. Instead, be simple and allocate a buffer big enough.
