* unshare: drop potential euid privileges before execKarel Zak2010-05-062-0/+10
| | | | | | | | | | | This patch drops potential euid privileges before executing the target program. This allows to setuid unshare. The unshare(1) is still distributed as non-setuid program. Based on patch from Martin Pohlack <mp26@os.inf.tu-dresden.de>. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | Fixes commit c9239f23acdc8b50f8bcbfadf967c6a490fd4693. The author didn't care for matching constraints when resorting the register constraints. The eax register (with the cpuid opcode) is now in operand 1, not zero anymore. Signed-off-by: Henne Vogelsang <hvogel@opensuse.org>

* flock: fix hang when parent ignores SIGCHLDMike Frysinger2009-12-071-1/+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.

* ipcs: use __GLIBC__ instead of obsolete __GNU_LIBRARY__Guillem Jover2009-10-091-3/+1Star
| | | | | | | | The latter is obsolete and it's currently defined to 6 for historical reasons (as per comment in <features.h>) instead of 2 as what would be expected. Signed-off-by: Guillem Jover <guillem@hadrons.org>
* build-sys: check for union semun instead of using _SEM_SEMUN_UNDEFINEDGuillem Jover2009-10-092-6/+2Star
| | | | | | | | | | | | | | 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.

* unshare: new commandMikhail Gusarov2009-10-064-0/+183
| | | | | | | | | | | | New utility allows to run process with separate mount, UTC, IPC or network namespaces. [kzak@redhat.com: - some cosmetic changes in usage() and err() usage - move "if BUILD_UNSHARE" to separate place in Makefile.am - add unshare to .gitignore] Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Karel Zak <kzak@redhat.com>
* fallocate: new commandKarel Zak2009-09-224-0/+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>
