* improve [f]stat[v]fs functions, and possibly work around old kernelsRich Felker2013-07-191-2/+5
| | | | | | | | | | | | | | | | | the main aim of this patch is to ensure that if not all fields are filled in, they contain zeros, so as not to confuse applications. reportedly some older kernels, including commonly used openvz kernels, lack the f_flags field, resulting in applications reading random junk as the mount flags; the common symptom seems to be wrongly considering the filesystem to be mounted read-only and refusing to operate. glibc has some amazingly ugly fallback code to get the mount flags for old kernels, but having them really is not that important anyway; what matters most is not presenting incorrect flags to the application. I have also aimed to fill in some fields of statvfs that were previously missing, and added code to explicitly zero the reserved space at the end of the structure, which will make things easier in the future if this space someday needs to be used.
* fix mknod and mknodat to accept large dev_t valuesRich Felker2013-05-162-5/+2
| | | | | | | | support for these was recently added to sysmacros.h. note that the syscall argument is a long, despite dev_t being 64-bit, so on 32-bit archs the high bits will be lost. it appears the high bits are just glibc silliness and not part of the kernel api, anyway, but it's nice that we have them there for future expansion if needed.
* add obsolete futimesat()rofl0r2012-12-061-0/+9
| | | | | | this function is obsolete, however it's available as a syscall and as such qemu userspace emulation tries to forward it to the host kernel.
* use restrict everywhere it's required by c99 and/or posix 2008Rich Felker2012-09-064-4/+4
| | | | | | | | to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
* add LSB ABI __xstat, etc. junkRich Felker2012-05-314-0/+36

* fix statvfs.c to match new fsid_t definitionRich Felker2011-09-201-1/+1
|
* fix the definition of struct statvfs to match lsb abiRich Felker2011-09-192-19/+46
| | | | | at the same time, make struct statfs match the traditional definition and make it more useful, especially the fsid_t stuff.
