* hwclock: internationalizing the message of the used interfaceBenno Schulenberg2014-02-104-4/+4
| | | | | | In addition, do it in a single sentence instead of in two fragments. Signed-off-by: Benno Schulenberg <bensberg@justemail.net>
* setpriv: Fix --apparmor-profileAndy Lutomirski2014-02-101-2/+2
| | | | | | | | | | | | | | | There were two bugs. First, trying to access /proc/self/attr/exec with O_CREAT | O_EXCL has no chance of working. Second, it turns out that the correct command to send is "exec", not "changeprofile". Of course, there was no way to know this until: commit 3eea57c26e49a5add4c053a031cc2a1977b7c48e Author: John Johansen <john.johansen@canonical.com> Date: Wed Feb 27 03:44:40 2013 -0800 apparmor: fix setprocattr arg processing for onexec Signed-off-by: Andy Lutomirski <luto@amacapital.net>

* dmesg: -w output not line-bufferedKarel Zak2014-02-061-0/+2
| | | | | | | | when writing to e.g. a pipe, output from dmesg -w can come many minutes late due to buffering. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1060925 Signed-off-by: Karel Zak <kzak@redhat.com>
* include/c.h: prefer nanosleep() over usleep()Karel Zak2014-01-242-2/+2
| | | | | | | | | | | | | | Let's use nanosleep() although if usleep() exists. The nanosleep function does no interact with signals and other timers. The patch introduces xusleep() as replacement to libc (or our fallback) usleep(). Yes, we don't want to use struct timespec + nanosleep() everywhere in code as nano-time resolution is useless for us. The patch also enlarges delays in some busy wait loops. It seems enough to try read/write 4x per second. Signed-off-by: Karel Zak <kzak@redhat.com>

* unshare: Add possibility to add mapping into root user in user namespaceLubomir Rintel2014-01-072-2/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes it very convenient to use make use of privileged actions on CONFIG_USER_NS enabled kernels, without having to manually tinker with uid_map and gid_map to obtain required credentials (as those given upon unshare() vanish with call to execve() and lot of userspace checks for euid==0 anyway). Usage example: $ unshare --uts unshare: unshare failed: Operation not permitted $ unshare --user --uts [nfsnobody@odvarok ~]$ hostname swag hostname: you must be root to change the host name $ unshare -r --uts [root@odvarok util-linux]# hostname swag [root@odvarok util-linux]# [kzak@redhat.com: - move code to map_id() - use all-io.h - add paths to pathnames.h] Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Karel Zak <kzak@redhat.com>
* lscpu: support discontinuous NUMA nodesKarel Zak2014-01-061-7/+43
| | | | | | | | | | | lscpu fails to print proper NUMA node values in a system with discontinuous nodes. This patch adds support by creating a nodeidx array to map node numbers.

* umount: fix umount by tag for non-rootsKarel Zak2013-11-191-3/+5
| | | | | | | | | $ umount LABEL=foo currently does not work for non-root users as umount uses the LABEL= as a path in sanitize_path(). Signed-off-by: Karel Zak <kzak@redhat.com>
* mount: make NAME=value tags usable for non-rootKarel Zak2013-11-191-4/+22
| | | | | | | | | | | | | | | The libmount does not care if we set source or target, it's able to swap it, but the mount.c function sanitize_paths() does not work as expected if we set NAME=value as target. It means that $ mount LABEL=foo does not work for non-root users (since 51e3530cdcb1d4f3ab91ae953ebc5adcdc5f9239, v2.24). This patch also checks if source or target is specified more than once.

* unshare: add more hints about mount namespaces to the man pageKarel Zak2013-11-181-2/+8
| | | | | | | | There is also idea (by Lennart) to add --propagation=[shared|private|slave|off] to unshare(1), but it seems unnecessary and too complex as everyone can call mount(8) after unshare(1) to setup a proper namespace. Signed-off-by: Karel Zak <kzak@redhat.com>
* mount: correct mount man page default iso9660 permissionPhillip Susi2013-11-141-1/+1
