2012-10-30shared, core: do not always accept numbers in string lookupsMichal Schmidt
The behaviour of the common name##_from_string conversion is surprising. It accepts not only the strings from name##_table but also any number that falls within the range of the table. The order of items in most of our tables is an internal affair. It should not be visible to the user. I know of a case where the surprising numeric conversion leads to a crash. We will allow the direct numeric conversion only for the tables where the mapping of strings to numeric values has an external meaning. This holds for the following lookup tables: - netlink_family, ioprio_class, ip_tos, sched_policy - their numeric values are stable as they are defined by the Linux kernel interface. - log_level, log_facility_unshifted - the well-known syslog interface. We allow the user to use numeric values whose string names systemd does not know. For instance, the user may want to test a new kernel featuring a scheduling policy that did not exist when his systemd version was released. A slightly unpleasant effect of this is that the name##_to_string conversion cannot return pointers to constant strings anymore. The strings have to be allocated on demand and freed by the caller.
2012-10-30shared, libsystemd-daemon: check for empty strings in strto*l conversionsMichal Schmidt
strtol() and friends may set EINVAL if no conversion was performed, but they are not required to do so. In practice they don't. We need to check for it. https://bugzilla.redhat.com/show_bug.cgi?id=870577
2012-10-29util: improve overflow checksMichal Schmidt
commit 49371bb fixed the observed division by zero, but missed another occurrence of the same bug. It was also not the optimal fix. We can simply make the divisor a constant by swapping it with the compared value.
2012-10-29util: avoid divide by zero FPEDave Reisner
In early userspace, if kernel initialization happens extremely quickly, a call to systemd-timestamp can potentially result in division by zero. Ensure that the check in timespec_load, which only makes sense if tv_sec is greater than zero, is guarded by this condition.

2012-10-17hostnamed: allow UTF8 chars in pretty hostname againLennart Poettering
2012-10-17timedatectl: introduce new command line client for timedatedLennart Poettering
Much like logind has a client in loginctl, and journald in journalctl introduce timedatectl, to change the system time (incl. RTC), timezones and related settings.
2012-10-16util: properly handle -1 timespec/timevalLennart Poettering
2012-10-11journalctl: implement --since= and --until for filtering by timeLennart Poettering

2012-10-03dbus: add some more safety checks before accepting data from bus clientsLennart Poettering
2012-09-28logs-show: various cleanupsLennart Poettering
Among other cleanups this introduces a threshold for the size of binary blobs we serialize as integer arrays in the JSON output. THis can be disabled via --all.
2012-09-24util: don't export parsed_columnsLennart Poettering
2012-09-24journalctl: reset cached column count on SIGWINCHDave Reisner
This requires a little bit of tip-toeing around to explicitly avoid touching the environment from a sig handler. Instead, simply create a function to reset the var to its "unset" state, allowing the next call to columns() to recalculate and cache the new value.
2012-09-21shared: call va_end in all casesLukas Nykryn

2012-09-19util: define union dirent_storage and make use of it everywhereLennart Poettering
Make sure to allocate enough space for readdir_r(). https://bugzilla.redhat.com/show_bug.cgi?id=858754

2012-09-18util: introduce get_process_gid()Lennart Poettering
2012-09-17conf-parser: don't unescape parsed configuration strings by defaultLennart Poettering
In many cases this might have a negative effect since we drop escaping from strings where we better shouldn't have dropped it. If unescaping makes sense for some settings we can readd it later again, on a per-case basis. https://bugs.freedesktop.org/show_bug.cgi?id=54522
2012-09-17util: various cleanups for printing boot statusLennart Poettering
2012-09-16nspawn: use automatic cleanup for umaskZbigniew Jędrzejewski-Szmek
2012-09-14timedate: assorted improvementsLennart Poettering
- Make writing/reading of /etc/timezone dependendent of HAVE_SYSV_COMPAT - Introduce symlink_atomic() after all, and use it - Use relative symlink for /etc/localtime
2012-09-14util: more modernizationsLennart Poettering
2012-09-14util: various additional modernizationsLennart Poettering
2012-09-14util: modernize a few functions with automatic cleanup variablesLennart Poettering
Just trying to get the feel for it. And it's pretty cool.
2012-09-13macro: introduce _cleanup_free_ macro for automatic freeing of scoped vars ↵Lennart Poettering
and make use of it
2012-09-11util: rm_rf_children_dangerous: delete all descendants dangerouslyTom Gundersen
Call rm_rf_children_dangerous() recursively rather than falling back to rm_rf_children(). This fixes a bug in systemd-tmpfiles. The problem can easily be reproduced by: # mount /dev/sda1 /mnt # mkdir /mnt/test # echo "D /mnt" > /root/test.conf # systemd-tmpfiles --remove /root/test.conf Attempted to remove disk file system, and we can't allow that. rm_rf(/root/test): Operation not permitted Reported-by: Lukas Jirkovsky <l.jirkovsky@gmail.com>
2012-09-05nspawn: handle poweroff/reboot nicely in containersLennart Poettering
2012-08-22journal: move syslog specific calls out of util.cLennart Poettering
2012-08-22journald: split /dev/kmsg related stuff into its own .c fileLennart Poettering
2012-08-21shared/util: add fstab support for partuuid/partlabelDave Reisner
udev has supported this since 172, so it should be a safe (and welcome) addition for users of GPT partitioned disks.
2012-08-21shared/util: refactor fstab_node_to_udev_nodeDave Reisner
Since this is purely duplicated logic, separate it out into a small static function.
2012-08-21journalctl: really include .journal~ files in listingLennart Poettering
2012-08-20journalctl: output FSS key as QR code on generatingLennart Poettering
2012-08-14service: add options RestartPreventExitStatus and SuccessExitStatusLukas Nykryn
In some cases, like wrong configuration, restarting after error does not help, so administrator can specify statuses by RestartPreventExitStatus which will not cause restart of a service. Sometimes you have non-standart exit status, so this can be specified by SuccessfulExitStatus.
2012-08-13namespace: rework namespace supportLennart Poettering
- don't use pivot_root() anymore, just reuse root hierarchy - first create all mounts, then mark them read-only so that we get the right behaviour when people want writable mounts inside of read-only mounts - don't pass invalid combinations of MS_ constants to the kernel
2012-08-09journald: properly unescape messages from /dev/kmsgLennart Poettering
2012-07-26cgtop: use full terminal widthZbigniew Jędrzejewski-Szmek
2012-07-26log.h: new log_oom() -> int -ENOMEM, use itShawn Landden
also a number of minor fixups and bug fixes: spelling, oom errors that didn't print errors, not properly forwarding error codes, few more consistency issues, et cetera
2012-07-25use "Out of memory." consistantly (or with "\n")Shawn Landden
glibc/glib both use "out of memory" consistantly so maybe we should consider that instead of this. Eliminates one string out of a number of binaries. Also fixes extra newline in udev/scsi_id
