2014-01-24losetup: wait for udevKarel Zak1-0/+1
On system with /dev/lop-control the udevd creates /dev/loopN nodes. It seems better to wait a moment after unsuccessful open(/dev/loopN) and try it to open again. The problem is pretty visible on systems where udevd also modifies permission for loopN devices, then open() fails with EACCES when losetup executed by non-root user (but user who is in "disk" group).

2014-01-24include/c.h: prefer nanosleep() over usleep()Karel Zak2-8/+17
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>
2014-01-07unshare: Add possibility to add mapping into root user in user namespaceLubomir Rintel1-0/+3
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>

2013-09-12agetty: add \S to output /etc/os-release dataKarel Zak1-0/+1
This patch allows to use a new \S or \S{VARNAME} sequence in the /etc/issue file. The sequence prints data from /etc/os-release. The reason is to keep /etc/issue file distribution and release independent. The \S{ANSI_COLOR} is converted to the real terminal escape seq. For example: \S Kernel \r on an \m (\l) or more complex example: Welcome to \S{ANSI_COLOR}\S{NAME}0m \S{VERSION} Report bugs at \S{BUG_REPORT_URL}. See http://www.freedesktop.org/software/systemd/man/os-release.html fr more details about /etc/issue. Based on patch from Bill Nottingham <notting@redhat.com>.

2013-08-06losetup: use loop-control to explicitly ask for deviceKarel Zak1-0/+1
Now we use LOOP_CTL_GET_FREE ioctl to ask for free device, for example losetup -f foo.img Unfortunately, losetup(8) allows to ask for specified device losetup /dev/loop100 foo.img and in this case we assume that the device already exists in the system. This is incorrect, we should be able to use loop-control LOOP_CTL_ADD ioctl to ask for the specified device. Signed-off-by: Karel Zak <kzak@redhat.com>

2013-04-26include: add close_fd() for noticing write errors before close()Sami Kerola1-0/+19
Essentially this helper function is similar to close_stream(), but for file descriptors. When a file descriptors are close()'d status of write is often overlooked. The close_fd() will try to determine what happen to writes with fsync() before closing the file descriptor. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

2013-04-09loopdev: sync capacity after setting itJeff Mahoney1-0/+1
I recently tried to mount an hfsplus file system from an image file with a partition table by using the loop offset and sizelimit options to specify the location of the file system. hfsplus stores some metadata at a set offset from the end of the partition, so it's sensitive to the device size reported by the kernel. It worked with this: But failed with this: /dev/loop0: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /dev/loop1: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /proc/partitions shows the correct number of blocks to match the sizelimit. But if I set a breakpoint in mount before the mount syscall, I could see: 102400000 102432768 The kernel loop driver will set the gendisk capacity of the device at LOOP_SET_STATUS64 but won't sync it to the block device until one of two conditions are met: All open file descriptors referring to the device are closed (and it will sync when re-opened) or if the LOOP_SET_CAPACITY ioctl is called to sync it. Since mount opens the device and passes it directly to the mount syscall after LOOP_SET_STATUS64 without closing and reopening it, the sizelimit argument is effectively ignroed. The capacity needs to be synced immediately for it to work as expected. This patch adds the LOOP_SET_CAPACITY call to loopctx_setup_device since the device isn't yet released to the user, so it's safe to sync the capacity immediately.
