2015-04-23journal: add int↔audit type name mappingZbigniew Jędrzejewski-Szmek
2015-04-22journalctl: rework code that checks whether we have access to /var/log/journalLennart Poettering
- fix some memory leaks on error conditions - handle all error cases properly, and log about failures - move HAVE_ACL and no-HAVE_ACL code closer to each other
2015-04-22journal: don't force FS_NOCOW_FL on new journal files, but warn if it is missingLennart Poettering
This way users have the freedom to set or unset the FS_NOCOW_FL flag on their journal files by setting it on the journal directory. Since our default tmpfiles configuration now sets this flag on the directory the flag is set by default on new files, however people can opt-out of this by masking the tmpfiles file for it.
2015-04-12journal: use (void) to silence coverityZbigniew Jędrzejewski-Szmek
This shouldn't really fail and anyway not much we can do about it. CID #996292, #996294, #996295.

2015-04-08util: merge change_attr_fd() and chattr_fd()Lennart Poettering
2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
2015-04-06util: rework rm_rf() logicLennart Poettering
- Move to its own file rm-rf.c - Change parameters into a single flags parameter - Remove "honour sticky" logic, it's unused these days
2015-03-27fix gcc warnings about uninitialized variablesHarald Hoyer
like: src/shared/install.c: In function ‘unit_file_lookup_state’: src/shared/install.c:1861:16: warning: ‘r’ may be used uninitialized in this function [-Wmaybe-uninitialized] return r < 0 ? r : state; ^ src/shared/install.c:1796:13: note: ‘r’ was declared here int r; ^
2015-03-14journald: add syslog fields for audit messagesZbigniew Jędrzejewski-Szmek
Audit messages would be displayed as "unknown[1]". Also specify AUTH as facility... This seems to be the closest match (/* security/authorization messages */).
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-09Introduce loop_read_exact helperZbigniew Jędrzejewski-Szmek
Usually when using loop_read(), we want to read the full buffer. Add a helper that mirrors loop_write(), and returns 0 when full buffer was read, and an error otherwise. Use -ENODATA for the short read, to distinguish it from a read error.
2015-03-09journalctl: unlink without checking with access firstZbigniew Jędrzejewski-Szmek
It is more elegant to do this in one step. Coverity complains about the TOCTOU difference, but it is not an actual problem (CID #1237777).
2015-03-09journal: fix return codeZbigniew Jędrzejewski-Szmek
Introduced in fa6ac76083b8ff. Might be related to CID #1261724, but I don't know if coverity can recurse this deep.
2015-03-09journal-file: update format string to remove castZbigniew Jędrzejewski-Szmek
2015-03-09journal: align comments to make them more legibleZbigniew Jędrzejewski-Szmek
2015-03-08sd-journal: return error when we cannot open a fileZbigniew Jędrzejewski-Szmek
Lack of this caused journalctl not to display a hint about missing groups properly when the user lacks permissions.
2015-03-08journalctl: update hint now that we set ACL everywhereZbigniew Jędrzejewski-Szmek
2015-03-03Do not advertise .d snippets over main config fileZbigniew Jędrzejewski-Szmek
For daemons which have a main configuration file, there's little reason for the administrator to use configuration snippets. They are useful for packagers which need to override settings, but we shouldn't advertise that as the main way of configuring those services. https://bugs.freedesktop.org/show_bug.cgi?id=89397
2015-03-02journal: fix Inappropriate ioctl for device on ext4Cristian Rodríguez
Logs constantly show systemd-journald[395]: Failed to set file attributes: Inappropriate ioctl for device This is because ext4 does not support FS_NOCOW_FL. [zj: fold into one conditional as suggested on the ML and fix (preexisting) r/errno confusion in error message.]
2015-02-25journal: make skipping of exhausted journal files effective againMichal Schmidt
Commit 668c965af "journal: skipping of exhausted journal files is bad if direction changed" fixed a correctness issue, but it also significantly limited the cases where the optimization that skips exhausted journal files could apply. As a result, some journalctl queries are much slower in v219 than in v218. (e.g. queries where a "--since" cutoff should have quickly eliminated older journal files from consideration, but didn't.) If already in the initial iteration find_location_with_matches() finds no entry, the journal file's location is not updated. This is fine, except that: - We must update at least f->last_direction. The optimization relies on it. Let's separate that from journal_file_save_location() and update it immediately after the direction checks. - The optimization was conditional on "f->current_offset > 0", but it would always be 0 in this scenario. This check is unnecessary for the optimization.
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.
2015-02-12include <poll.h> instead of <sys/poll.h>Thomas Hindoe Paaboel Andersen
include-what-you-use automatically does this and it makes finding unnecessary harder to spot. The only content of poll.h is a include of sys/poll.h so should be harmless.
2015-02-12Add missing includes in header filesThomas Hindoe Paaboel Andersen
This fixes various issues found by globally reordering the include sections of all .c files.
2015-02-10journald: don't specify inline in local functionsLennart Poettering
Leave it to the compiler to figure out whether it shall inline stuff or not. Only place where using static inline is OK to use is in in header files, really.
2015-02-03journald: fix some xsprrintf() buffer size falloutLennart Poettering
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
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.
2015-01-29coredump: drop caps while we are processing the coredumpLennart Poettering

2015-01-29Revert "journal: do not check for number of files"Lennart Poettering
This reverts commit b914ea8d379b446c4c9fac4ba181771676ef38cd. We really need to put a limit on all our resources, everywhere, and in particular if we operate on external data. Hence, let's reintroduce the limit, but bump it substantially, so that it is guaranteed to be higher than any realistic RLIMIT_NOFILE setting.
2015-01-22tests: use assert_se instead of assertRonny Chevalier
Otherwise they can be optimized away with -DNDEBUG
2015-01-22tmpfiles: add 'a' type to set ACLsZbigniew Jędrzejewski-Szmek
2015-01-22Assorted format fixesZbigniew Jędrzejewski-Szmek
Types used for pids and uids in various interfaces are unpredictable. Too bad.
2015-01-22Fix some format strings for enums, they are signedZbigniew Jędrzejewski-Szmek
2015-01-22import: introduce new mini-daemon systemd-importd, and make machinectl a ↵Lennart Poettering
client to it The old "systemd-import" binary is now an internal tool. We still use it as asynchronous backend for systemd-importd. Since the import tool might require some IO and CPU resources (due to qcow2 explosion, and decompression), and because we might want to run it with more minimal priviliges we still keep it around as the worker binary to execute as child process of importd. machinectl now has verbs for pulling down images, cancelling them and listing them.
2015-01-21journal: Fix syslog forwarding without CAP_SYS_ADMINChristian Seiler
In case CAP_SYS_ADMIN is missing (like in containers), one cannot fake pid in struct ucred (uid/gid are fine if CAP_SETUID/CAP_SETGID are present). Ensure that journald will try again to forward the messages to syslog without faking the SCM_CREDENTIALS pid (which isn't guaranteed to succeed anyway, since it also does the same thing if the process has already exited). With this patch, journald will no longer silently discard messages that are supposed to be sent to syslog in these situations. https://bugs.debian.org/775067
2015-01-19journalctl: trim --help to fit in 80 columnsZbigniew Jędrzejewski-Szmek
Terminals tend to be 80 columns wide by default, and the help text is only supposed to be a terse reminder anyway. https://bugzilla.redhat.com/show_bug.cgi?id=1183771
2015-01-18Move DEFINE_TRIVIAL_CLEANUP_FUNC to macro.hZbigniew Jędrzejewski-Szmek
This remove the need for various header files to include the (relatively heavyweight) util.h.
2015-01-17remove unneeded libgen.h includesCristian Rodríguez
2015-01-13journald: allow zero length datagrams againLennart Poettering
This undoes a small part of 13790add4bf648fed816361794d8277a75253410 which was erroneously added, given that zero length datagrams are OK, and hence zero length reads on a SOCK_DGRAM be no means mean EOF.
2015-01-09journal: do not check for number of filesZbigniew Jędrzejewski-Szmek
Now that we bump rlimit, we do not really know how many files we can open. Remove the check. https://bugzilla.redhat.com/show_bug.cgi?id=1179980
2015-01-08journal: bump RLIMIT_NOFILE when journal files to 16K (if possible)Lennart Poettering
When there are a lot of split out journal files, we might run out of fds quicker then we want. Hence: bump RLIMIT_NOFILE to 16K if possible. Do these even for journalctl. On Fedora the soft RLIMIT_NOFILE is at 1K, the hard at 4K by default for normal user processes, this code hence bumps this up for users to 4K. https://bugzilla.redhat.com/show_bug.cgi?id=1179980

2015-01-08journald: turn off COW for journal files on btrfsLennart Poettering
btrfs' COW logic results in heavily fragment journal files, which is detrimental for perfomance. Hence, turn off COW for journal files as we create them. Turning off COW comes at the cost of data integrity guarantees, but this should be acceptable, given that we do our own checksumming, and generally have a pretty conservative write pattern. Also see discussion on linux-btrfs: http://www.spinics.net/lists/linux-btrfs/msg41001.html
2015-01-06journal: consider file deletion errors a reason for rotationLennart Poettering
2015-01-06journald: whenever we rotate a file, btrfs defrag itLennart Poettering
Our write pattern is quite awful for CoW file systems (btrfs...), as we keep updating file parts in the beginning of the file. This results in fragmented journal files. Hence: when rotating files, defragment them, since at that point we know that no further write accesses will be made.
