2013-04-03Preserve errno across _PC_CHOWN_RESTRICTED call on XFSSiddhesh Poyarekar1-0/+6
Fix BZ #15305. On kernel versions earlier than 2.6.29, the Linux kernel exported a sysctl called restrict_chown for xfs, which could be used to allow chown to users other than the owner. 2.6.29 removed this support, causing the open_not_cancel_2 to fail and thus modify errno. The fix is to save and restore errno so that the caller sees it as unmodified. Additionally, since the code to check the sysctl is not useful on newer kernels, we add an ifdef so that in future the code block gets rmeoved completely.

2011-05-15Fix a few problems in fopen and freopenUlrich Drepper1-1/+2
fopen should set the FD_CLOEXEC flag if requested evenif the kernel does not support an aotmic operation. freopen should reuse the file descriptor for the stream. This is especially important for calls to change the standard streams (stin, stdout, stderr).

The 2.6.36 kernel provides an additional field in the statfs results. Use this value in the statvfs emulation to avoid filling in f_flag the hard way.
