2015-10-27util-lib: move /proc/cmdline parsing code to proc-cmdline.[ch]Lennart Poettering
2015-10-27util-lib: move a number of fs operations into fs-util.[ch]Lennart Poettering
2015-10-27util-lib: split string parsing related calls from util.[ch] into parse-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24path-util: rework find_binary(), fsck_exists() and mkfs_exists()Lennart Poettering
Modernize the code a bit: - Get rid of FOREACH_WORD_SEPARATOR() loop in favour of a extract_first_word() loop. - Remove find_binary()'s "local" flag. It's not reasonably possible to look for binaries on remote systems, we hence should not pretend we could. - When we cannot find a suitable binary, return the last error returned from access() rather than ENOENT unconditionally. - Rework fsck_exists() and mkfs_exists() to return 1 on success, 0 if the implementation is missing and negative on real errors. This is more like we do it in other functions. - Make sure we also detect direct fsck symlinks to "true", rather than just absolute ones to /bin/true.

fsck: start reboot.target irreversibly
2015-09-29bus-util: rename bus_open_transport() to bus_connect_transport()Lennart Poettering
In sd-bus, the sd_bus_open_xyz() family of calls allocates a new bus, while sd_bus_default_xyz() family tries to reuse the thread's default bus. bus_open_transport() sometimes internally uses the former, sometimes the latter family, but suggests it only calls the former via its name. Hence, let's avoid this confusion, and generically rename the call to bus_connect_transport(). Similar for all related calls. And while we are at it, also change cgls + cgtop to do direct systemd connections where possible, since all they do is talk to systemd itself.
2015-09-27fsck: start reboot.target irreversiblyŁukasz Stelmach
In some situations rebooting after fixing rootfs fails because the job for reboot.target gets canceled. To avoid this the "mode" parameter of the StartUnitReplace() call needs to be set to "replace-irreversibly".
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327
2015-06-10tree-wide: whenever we fork off a foreign child process reset signal ↵Lennart Poettering
mask/handlers Also, when the child is potentially long-running make sure to set a death signal. Also, ignore the result of the reset operations explicitly by casting them to (void).
2015-05-29util: split out signal-util.[ch] from util.[ch]Lennart Poettering
No functional changes.
2015-05-12fsck: add enum with fsck exit codesThomas Hindoe Paaboel Andersen
2015-04-28fsck: remove fsckd again, but keep the door open for external replacementLennart Poettering
For a longer discussion see this: http://lists.freedesktop.org/archives/systemd-devel/2015-April/030175.html This introduces /run/systemd/fsck.progress as a simply AF_UNIX/SOCK_STREAM socket. If it exists and is connectable we'll connect fsck's -c switch with it. If external programs want to get progress data they should hence listen on this socket and will get all they need via that socket. To get information about the connecting fsck client they should use SO_PEERCRED. Unless /run/systemd/fsck.progress is around and connectable this change reverts back to v219 behaviour where we'd forward fsck output to /dev/console on our own.
2015-04-28fsck: minor improvementsLennart Poettering
Among other smaller fixes, explicitly check if we are invoked on a block device before making use of st.st_rdev.

2015-03-19fsck: use %zu for size_tThomas Hindoe Paaboel Andersen
cur and max were changed to size_t in ac6e2f0dfc2e800f01c79ecea2b811914110a7b9 update the format accordingly.

2015-03-03fsck: remove unnecessary checkZbigniew Jędrzejewski-Szmek
gcc was complaining that progress_rc might be used uninitalized. But it was actually always set, because the condition was always satisfied. Remove the condition.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-18Connect to plymouth and support cancellation of in progress fsckDidier Roche
Try to connect and send to plymouth (if running) some checked report progress, using direct plymouth protocole. Update message is the following: fsckd:<num_devices>:<progress>:<string> * num_devices corresponds to the current number of devices being checked (int) * progress corresponds to the current minimum percentage of all devices being checked (float, from 0 to 100) * string is a translated message ready to be displayed by the plymouth theme displaying the information above. It can be overriden by plymouth themes supporting i18n. Grab in fsckd plymouth watch key Control+C, and propagate this cancel request to systemd-fsck which will terminate fsck. Send a message to signal to user what key we are grabbing for fsck cancel. Message is: fsckd-cancel-msg:<string> Where string is a translated string ready to be displayed by the plymouth theme indicating that Control+C can be used to cancel current checks. It can be overriden (matching only fsckd-cancel-msg prefix) for themes supporting i18n.
2015-02-18systemd-fsck: always connect to systemd-fsckdDidier Roche
Remove the plymouth running or show-status checks from systemd-fsck. Instead, always connect to systemd-fsckd socket, and let this one decide if we display progress or not.
2015-02-18fsckd daemon for inter-fsckd communicationDidier Roche
Add systemd-fsckd multiplexer which accepts multiple systemd-fsck instances to connect to it and sends progress report. systemd-fsckd then computes and writes to /dev/console the number of devices currently being checked and the minimum fsck progress. This will be used for interactive progress report and cancelling in plymouth. systemd-fsckd stops on idle when no systemd-fsck is connected. Make the necessary changes to systemd-fsck to connect to the systemd-fsckd socket.
2015-02-01Add a snprinf wrapper which checks that the buffer was big enoughZbigniew Jędrzejewski-Szmek
If we scale our buffer to be wide enough for the format string, we should expect that the calculation was correct. char_array_0() invocations are removed, since snprintf nul-terminates the output in any case. A similar wrapper is used for strftime calls, but only in timedatectl.c.
2014-12-10sd-bus: move common errors src/shared/bus-errors.h → ↵Lennart Poettering
src/libsystemd/sd-bus/bus-common-errors.h Stuff in src/shared/ should not use stuff from src/libsystemd/ really.
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-07util: simplify proc_cmdline() to reuse get_process_cmdline()Lennart Poettering
Also, make all parsing of the kernel cmdline non-fatal.
2014-10-22fsck: re-enable fsck -lKarel Zak
The -l (lock) has been temporary disabled due to conflict with udev (https://bugs.freedesktop.org/show_bug.cgi?id=79576) The problem is fixed since util-linux v2.25 (Jul 2014).
2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.

2014-05-30fsck: include device name in the message about missing fsckZbigniew Jędrzejewski-Szmek
2014-05-16fsck: Allow to specify the fsck repair option in the cmdlineHolger Hans Peter Freyther
Some unattended systems do not have a console attached and entering the default rescue mode will not be too helpful. Allow to specify the "-y" option to attempt to fix all filesystem errors. Manually verified by downloading an image.gz of e2fsprogs, using losetup and running systemd-fsck on the loop device and varying the fsck.repair=preen|yes|no option.
2014-04-12fsck: Search for fsck.type in PATHMike Gilbert
Modifies find_binary() to accept NULL in the second argument. fsck.type lookup logic moved to new fsck_exists() function, with a test.
2014-03-24util: replace close_pipe() with new safe_close_pair()Lennart Poettering
safe_close_pair() is more like safe_close(), except that it handles pairs of fds, and doesn't make and misleading allusion, as it works similarly well for socketpairs() as for pipe()s...
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-06util: move more intellegince into parse_proc_cmdline()Lennart Poettering
Already split variable assignments before invoking the callback. And drop "rd." settings if we are not in an initrd.
2014-02-17Extract looping over /proc/cmdline into a shared functionZbigniew Jędrzejewski-Szmek
In cryptsetup-generator automatic cleanup had to be replaced with manual cleanup, and the code gets a bit longer. But existing code had the issue that it returned negative values from main(), which was wrong, so should be reworked anyway.

2013-11-15fsck,fstab-generator: be lenient about missing fsck.<type>Zbigniew Jędrzejewski-Szmek
If fstab contains 1 for passno, treat this as an error, but only warn briefly. If fstab doesn't contain this information, don't complain at all. Patch is complicated a bit by the fact that we might have the fstype specified in fstab or on /proc/cmdline, in which case we can check if we have the appropriate fsck tool, or not specified, or specified as auto, in which case we have to look and check the type of the filesystem ourselves. It cannot be done before the device appears, so it is too early in the generator phase, and it must be done directly in fsck service.
