2013-04-25coredump: use realloc() loop instead of malloc(768M)Colin Walters
I typically run VMs with 1024MiB allocated; systemd is unable to write coredumps in this scenario at all because the default kernel configuration will only overcommit 50% of available RAM. Avoid this failure by using a realloc() loop. See: http://lists.freedesktop.org/archives/systemd-devel/2013-April/010709.html

2013-04-22cgroup: make sure all our cgroup objects have a suffix and are properly escapedLennart Poettering
Session objects will now get the .session suffix, user objects the .user suffix, nspawn containers the .nspawn suffix. This also changes the user cgroups to be named after the numeric UID rather than the username, since this allows us the parse these paths standalone without requiring access to the cgroup file system. This also changes the mapping of instanced units to cgroups. Instead of mapping foo@bar.service to the cgroup path /user/foo@.service/bar we will now map it to /user/foo@.service/foo@bar.service, in order to ensure that all our objects are properly suffixed in the tree.
2013-04-19Reintroduce f_type comparison macroHarald Hoyer
This reverts commit 4826f0b7b5c0aefa08b8cc7ef64d69027f84da2c. Because statfs.t_type can be int on some architecures, we have to cast the const magic to the type, otherwise the compiler warns about signed/unsigned comparison, because the magic can be 32 bit unsigned. statfs(2) man page is also wrong on some systems, because f_type is not __SWORD_TYPE on some architecures. The following program: int main(int argc, char**argv) { struct statfs s; statfs(argv[1], &s); printf("sizeof(f_type) = %d\n", sizeof(s.f_type)); printf("sizeof(__SWORD_TYPE) = %d\n", sizeof(__SWORD_TYPE)); printf("sizeof(long) = %d\n", sizeof(long)); printf("sizeof(int) = %d\n", sizeof(int)); if (sizeof(s.f_type) == sizeof(int)) { printf("f_type = 0x%x\n", s.f_type); } else { printf("f_type = 0x%lx\n", s.f_type); } return 0; } executed on s390x gives for a btrfs: sizeof(f_type) = 4 sizeof(__SWORD_TYPE) = 8 sizeof(long) = 8 sizeof(int) = 4 f_type = 0x9123683e

2013-04-18Revert f_type fixupsHarald Hoyer
This reverts commit a858b64dddf79177e12ed30f5e8c47a1471c8bfe. This reverts commit aea275c43194b6ac519ef907b62c5c995050fde0. This reverts commit fc6e6d245ee3989c222a2a8cc82a33475f9922f3. This reverts commit c4073a27c555aeceac87a3b02a83141cde641a1e. This reverts commit cddf148028f525be8176e7f1cbbf4f862bd287f6. This reverts commit 8c68a70170b31f93c287f29fd06c6c17edaf19ad. The constants are now casted to __SWORD_TYPE, which should resolve the compiler warnings about signed vs unsigned. After talking to Kay, we concluded: This should be fixed in the kernel, not worked around in userspace tools. Architectures cannot use int and expect magic constants lager than INT_MAX to work correctly. The kernel header needs to be fixed. Even coreutils cannot handle it: #define RAMFS_MAGIC 0x858458f6 # stat -f -c%t / ffffffff858458f6 #define BTRFS_SUPER_MAGIC 0x9123683E # stat -f -c%t /mnt ffffffff9123683e Although I found the perfect working macro to fix the thing :) __extension__ ({ \ bool _ret = false; \ switch(f) { case c: _ret=true; }; \ ( _ret ); \ })

2013-04-18rename CMP_F_TYPE to F_TYPE_CMPHarald Hoyer
2013-04-18Add ugly CMP_F_TYPE() macroHarald Hoyer
On some architectures (like s390x) the kernel has the type int for f_type, but long in userspace. Assigning the 32 bit magic constants from linux/magic.h to the 31 bit signed f_type in the kernel, causes f_type to be negative for some constants. glibc extends the int to long for those architecures in 64 bit mode, so the negative int becomes a negative long, which cannot be simply compared to the original magic constant, because the compiler would automatically cast the constant to long. To workaround this issue, we also compare to the (int)MAGIC value in a macro. Of course, we could do #ifdef with the architecure, but it has to be maintained, and the magic constants are 32 bit anyway. Someday, when the int is unsigned or long for all architectures, we can remove this macro again. Until then, keep it as simple as it can be.

2013-04-17fixup for cddf148028f52Harald Hoyer
Instead of making a type up, just use __SWORD_TYPE, after reading statfs(2). Too bad, this does not fix s390x because __SWORD_TYPE is (long int) and the kernel uses (int) to fill in the field!!!!!!
2013-04-17fixup 8c68a7017 and cast to (unsigned long)Harald Hoyer
2013-04-17fixed statfs.f_type signed vs unsigned comparisonsHarald Hoyer
statfs.f_type is signed but the filesystem magics are unsigned. Casting the magics to signed will not make the signed. Problem seen on big-endian 64bit s390x with __fsword_t 8 bytes. Casting statfs.f_type to unsigned on the other hand will get us what we need. https://bugzilla.redhat.com/show_bug.cgi?id=953217
2013-04-17journalctl: specify "--unit=" and "--user-unit" multiple timesHarald Hoyer
Previously only one "--unit=" or "--user-unit" could be specified. With this patch, journalcrtl can show multiple units. $ journalctl -u systemd-udevd.service -u sshd.service -u crond.service -b -- Logs begin at Sa 2013-03-23 11:08:45 CET, end at Fr 2013-04-12 09:10:22 CEST. -- Apr 12 08:41:37 lenovo systemd[1]: Started udev Kernel Device Manager.

2013-04-17journal: add one more level on top with ANDHarald Hoyer
When using "-p" and "-b" in combination with "-u", the output is not what you would expect. The reason is the sd_journal_add_disjunction() call in add_matches_for_unit() and add_matches_for_user_unit(), which adds two ORs without taking the other conditions to every OR. Adding another level on top with AND and sd_journal_add_conjunction() solves the problem. Output before: $ journalctl -o short-monotonic -ab -p 0 -u sshd.service -- Reboot -- [ 3.216305] lenovo systemd[1]: Starting OpenSSH server daemon... -- Reboot -- [ 3.168666] lenovo systemd[1]: Starting OpenSSH server daemon...

2013-04-17journalctl: show fields requested with --field in fullZbigniew Jędrzejewski-Szmek
I see little point in silently truncating fields when they are explictly requested. With this change e.g. journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518 --field=BOOTCHART works as expected.
2013-04-17Report about syntax errors with metadataZbigniew Jędrzejewski-Szmek
The information about the unit for which files are being parsed is passed all the way down. This way messages land in the journal with proper UNIT=... or USER_UNIT=... attribution. 'systemctl status' and 'journalctl -u' not displaying those messages has been a source of confusion for users, since the journal entry for a misspelt setting was often logged quite a bit earlier than the failure to start a unit.

2013-04-16nspawn: introduce the new /machine/ tree in the cgroup tree and move ↵Lennart Poettering
containers there Containers will now carry a label (normally derived from the root directory name, but configurable by the user), and the container's root cgroup is /machine/<label>. This label is called "machine name", and can cover both containers and VMs (as soon as libvirt also makes use of /machine/). libsystemd-login can be used to query the machine name from a process. This patch also includes numerous clean-ups for the cgroup code.

2013-04-05Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek
Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.

2013-04-04journal: add public API call sd_journal_get_events()Lennart Poettering
This function should be used when filling in "struct pollfd"'s .events field for watching the journal. It will always return POLLIN for now, but we should keep our options open to change this later on. This mimics libsystemd-bus' sd_bus_get_events() call with the same purpose.
2013-04-04util: make time formatting a bit smarterLennart Poettering
Instead of outputting "5h 55s 50ms 3us" we'll now output "5h 55.050003s". Also, while outputting the accuracy is configurable. Basically we now try use "dot notation" for all time values > 1min. For >= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and finally 'us'. This should give reasonably values in most cases.
2013-04-03util: rename parse_usec() to parse_sec() sinds the default unit is secondsLennart Poettering
Internally we store all time values in usec_t, however parse_usec() actually was used mostly to parse values in seconds (unless explicit units were specified to define a different unit). Hence, be clear about this and name the function about what we pass into it, not what we get out of it.

2013-04-01Always use our own MAX/MIN definitionsCristian Rodríguez
code in src/shared/macro.h only defined MAX/MIN in case they were not defined previously. however the MAX/MIN macros implemented in glibc are not of the "safe" kind but defined as: define MIN(a,b) (((a)<(b))?(a):(b)) define MAX(a,b) (((a)>(b))?(a):(b)) Avoid nasty side effects by using our own versions instead. Also fix the warnings derived from this change. [zj: - modify MAX3 macro to fix warning about _a shadowing _a, - do bootchart/svg.c too, - remove unused MIN3.]

This makes it possible to make test-catalog part of the normal test suite, since it now only operates on files in /tmp. Some more tests are added.
