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
https://bugs.freedesktop.org/show_bug.cgi?id=87354
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.
2015-01-06tree-wide: remove unnecessary LOG_PRIZbigniew Jędrzejewski-Szmek
LOG_DEBUG is already a log level, there is no need to use LOG_PRI which is for filtering out the facility.
2015-01-06journald: allow restarting journald without losing stream connectionsLennart Poettering
Making use of the fd storage capability of the previous commit, allow restarting journald by serilizing stream state to /run, and pushing open fds to PID 1.
2015-01-05journald: reuse IOVEC_TOTAL_SIZE() macros where possibleLennart Poettering

2015-01-05journald: add some additional checks before we divide by values read from ↵Lennart Poettering
journal file headers Since the file headers might be replaced by zeroed pages now due to sigbus we should make sure we don't end up dividing by zero because we don't check values read from journal file headers for changes.
2015-01-05journalctl: static variables immediately configured via command line ↵Lennart Poettering
arguments should be prefixed with "arg_"
2015-01-05journal: install sigbus handler for journal tools tooLennart Poettering
This makes them robust regarding truncation. Ideally, we'd export this as an API, but given how messy SIGBUS handling is, and the uncertain ownership logic of signal handlers we should not do this (unless libc one day invents a scheme how to sanely install SIGBUS handlers for specific memory areas only). However, for now we can still make all our own tools robust. Note that external tools will only have read-access to the journal anyway, where SIGBUS is much more unlikely, given that only writes are subject to disk full problems.
2015-01-05journald: constify all thingsLennart Poettering
2015-01-05journald: prefix exported calls with "server_", unexport unnecessary callsLennart Poettering
2015-01-05journald: process SIGBUS for the memory maps we set upLennart Poettering
Even though we use fallocate() it appears that file systems like btrfs will trigger SIGBUS on certain low-disk-space situation. We should handle that, hence catch the signal, add it to a list of invalidated pages, and replace the page with an empty memory area. After each write check if SIGBUS was triggered, and consider the write invalid if it was. This should make journald a lot more robust with file systems where fallocate() is not reliable, for example all CoW file systems (btrfs...), where changing written data can fail with disk full errors. https://bugzilla.redhat.com/show_bug.cgi?id=1045810

2014-12-26journald: always allocate space for object fieldsZbigniew Jędrzejewski-Szmek
If OBJECT_PID= came as the last field, we would not reallocate the iovec to bigger size, and fail the assertion later on in dispatch_message_real().

2014-12-24util: fix strict aliasing violations in use of struct inotify_event v5Shawn Paul Landden
There is alot of cleanup that will have to happen to turn on -fstrict-aliasing, but I think our code should be "correct" to the rule.
2014-12-19journal: skipping of exhausted journal files is bad if direction changedMichal Schmidt
EOF is meaningless if the direction of iteration changes. Move the EOF optimization under the direction check. This fixes test-journal-interleaving for me. Thanks to Filipe Brandenburger for telling me about the failure.
2014-12-19journal: make next_with_matches() always use f->current_offsetMichal Schmidt
next_with_matches() is odd in that its "unit64_t *offset" parameter is both input and output. In other it's purely for output. The function is called from two places in next_beyond_location(). In both of them "&cp" is used as the argument and in both cases cp is guaranteed to equal f->current_offset. Let's just have next_with_matches() ignore "*offset" on input and operate with f->current_offset. I did not investigate why it is, but it makes my usual benchmark run reproducibly faster: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m4.032s user 0m3.896s sys 0m0.135s (Compare to preceding commit, where real was 4.4s.)
