2010-01-07lscpu: add {32,64}-bit CPU modes detectionKarel Zak1-0/+35

2009-12-07flock: fix hang when parent ignores SIGCHLDMike Frysinger1-1/+9
If flock is executed from a process which has set SIGCHLD to SIG_IGN, then flock will eat cpu and hang indefinitely if given a command to execute. So before we fork(), make sure to set SIGCHLD handling back to the default so that the later waitpid() doesn't freak out on us.

2009-10-09ipcs: use __GLIBC__ instead of obsolete __GNU_LIBRARY__Guillem Jover1-3/+1

2009-10-09build-sys: check for union semun instead of using _SEM_SEMUN_UNDEFINEDGuillem Jover2-6/+2
Older versions of glibc used to declare ‘union semun’ in <sys/sem.h>, but POSIX.1-2001 requires the caller to declare it instead. Later versions of glibc started defining _SEM_SEMUN_UNDEFINED to note that the union was not being declared, but conforming systems are not required to define that macro (e.g. FreeBSD). As a side effect we get rid of some obsolete __GNU_LIBRARY__ macro usage.

2009-09-22fallocate: new commandKarel Zak4-0/+230
The fallocate(1) utility is used to preallocate blocks to a file. This can be useful for virtual images, database files, testing, etc. Normally we'd hope that various tools will start using preallocation internally, but until then such a utility may be useful, and could be scripted as well. The original Eric's version is available at: http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2490 This version: - checks for fallocate glibc function and kernel syscall - does not provide a fallback and does not call posix_fallocate() - adds long options - uses err.h for errro messages - adds NLS support - cleanups man page Co-Author: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

2009-07-14switch_root: add subroot supportDaniel Drake1-5/+76
The current switch_root can only switch to a new root that is the root of a mount point. This patch adds support for "subroots", where the new root is somewhere below a mount point. It does this by adding in a few extra steps to chroot into the subroot after the enclosing partition has been moved and entered. This will be used by OLPC, who sort-of have 2 copies of Fedora stored on a single partition under different directory trees, where the initramfs decides which one to boot into [kzak@redhat.com: - port to the current u-l-ng switch_root code - don't use static buffer for "dir" in get_parent_mount()] CC: Peter Jones <pjones@redhat.com> Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Karel Zak <kzak@redhat.com>
2009-07-04build-sys: rename to _execdirKarel Zak1-9/+9
The variable name "usrlibexecdir" is very confusing (because we have /usr/libexec). The "exec" prefix is required for user-defined directories, see http://www.gnu.org/software/hello/manual/automake/The-Two-Parts-of-Install.html#The-Two-Parts-of-Install This patch renames all usr*execdir variables to usr*_execdir.
