2016-04-25machined: add CAP_MKNOD to capabilities to run with (#3116)Lennart Poettering
Container images from Debian or suchlike contain device nodes in /dev. Let's make sure we can clone them properly, hence pass CAP_MKNOD to machined. Fixes: #2867 #465
2016-04-25machined: generate a nicer error when the user tries "machinectl clone" on ↵Lennart Poettering
non-btrfs file systems (#3117) Fixes: #2060 (Of course, in the long run, we should probably add a copy-based fall-back. But given how slow that is, this probably requires some asynchronous forking logic like the CopyFrom() and CopyTo() method calls already implement.)
2016-04-25core: fix description of "resources" service error (#3119)Lennart Poettering
The "resources" error is really just the generic error we return when we hit some kind of error and we have no more appropriate error for the case to return, for example because of some OS error. Hence, reword the explanation and don't claim any relation to resource limits. Admittedly, the "resources" service error is a bit of a misnomer, but I figure it's kind of API now. Fixes: #2716

2016-04-25journal: fix already offline check and thread leak (#2810)Vito Caputo
Early in journal_file_set_offline() f->header->state is tested to see if it's != STATE_ONLINE, and since there's no need to do anything if the journal isn't online, the function simply returned here. Since moving part of the offlining process to a separate thread, there are two problems here: 1. We can't simply check f->header->state, because if there is an offline thread active it may modify f->header->state. 2. Even if the journal is deemed offline, the thread responsible may still need joining, so a bare return may leak the thread's resources like its stack. To address #1, the helper journal_file_is_offlining() is called prior to accessing f->header->state. If journal_file_is_offlining() returns true, f->header->state isn't even checked, because an offlining journal is obviously online, and we'll just continue with the normal set offline code path. If journal_file_is_offlining() returns false, then it's safe to check f->header->state, because the offline_state is beyond the point of modifying f->header->state, and there's a memory barrier in the helper. If we find f->header->state is != STATE_ONLINE, then we call the idempotent journal_file_set_offline_thread_join() on the way out of the function, to join a potential lingering offline thread.
2016-04-25journalctl: turn --unit= in combination with --user into --user-unit=Lennart Poettering
Let's be nice to users, and let's turn the nonsensical "--unit=… --user" into "--user-unit=…" which the user more likely meant. Fixes #1621
2016-04-25man: document the new by-fd journal callsLennart Poettering
Also, remove documentation for sd_journal_open_container() as we consider it deprecated now.
2016-04-25man: don't include history sections in man pagesLennart Poettering
I am pretty sure we shouldn't carry history sections in man pages, since it's very hard to keep them correctly updated, the current ones are very out-of-date, and they tend to make APIs appear unnecessarily complex.
2016-04-25sd-journal: "soft" deprecate sd_journal_open_container()Lennart Poettering
Let's document the call as deprecated, since it doesn't cover containers with directories that aren#t visible to the host properly.
2016-04-25journalctl: port --machine= switch to use machined's OpenMachineRootDirectory()Lennart Poettering
This way, the switch becomes compatible with nspawn containers using --image=, and those which only store journal data in /run (i.e. have persistant logs off). Fixes: #49
2016-04-25journalctl: don't trust the per-field entry tables when looking for boot IDsLennart Poettering
When appending to a journal file, journald will: a) first, append the actual entry to the end of the journal file b) second, add an offset reference to it to the global entry array stored at the beginning of the file c) third, add offset references to it to the per-field entry array stored at various places of the file The global entry array, maintained by b) is used when iterating through the journal without matches applied. The per-field entry array maintained by c) is used when iterating through the journal with a match for that specific field applied. In the wild, there are journal files where a) and b) were completed, but c) was not before the files were abandoned. This means, that in some cases log entries are at the end of these files that appear in the global entry array, but not in the per-field entry array of the _BOOT_ID= field. Now, the "journalctl --list-boots" command alternatingly uses the global entry array and the per-field entry array of the _BOOT_ID= field. It seeks to the last entry of a specific _BOOT_ID=field by having the right match installed, and then jumps to the next following entry with no match installed anymore, under the assumption this would bring it to the next boot ID. However, if the per-field entry wasn't written fully, it might actually turn out that the global entry array might know one more entry with the same _BOOT_ID, thus resulting in a indefinite loop around the same _BOOT_ID. This patch fixes that, by updating the boot search logic to always continue reading entries until the boot ID actually changed from the previous. Thus, the per-field entry array is used as quick jump index (i.e. as an optimization), but not trusted otherwise. Only the global entry array is trusted. This replaces PR #1904, which is actually very similar to this one. However, this one actually reads the boot ID directly from the entry header, and doesn't try to read it at all until the read pointer is actually really located on the first item to read. Fixes: #617 Replaces: #1904
2016-04-25journalctl: improve output of --header a bitLennart Poettering
Show the various timestamps in hexadecimal too. This is useful for matching the timestamps included in cursor strings (which are encoded in hex, too), with the references in the journal header.
2016-04-25nspawn: explicitly remove veth links after use (#3111)Lennart Poettering
* sd-netlink: permit RTM_DELLINK messages with no ifindex This is useful for removing network interfaces by name. * nspawn: explicitly remove veth links we created after use Sometimes the kernel keeps veth links pinned after the namespace they have been joined to died. Let's hence explicitly remove veth links after use. Fixes: #2173
2016-04-25journalctl: simplify discover_next_boot() a bitLennart Poettering
Drop the "read_realtime" parameter. Getting the realtime timestamp from an entry is cheap, as it is a normal header field, hence let's just get this unconditionally, and simplify our code a bit.
2016-04-25journalctl: simplify get_boots() a bit, by getting rid of one BootId objectLennart Poettering
Let's store the reference as simple sd_id128_t, since we don't actually need a BootId for it.
2016-04-25journalctl: add some explanatory comments to get_boots()Lennart Poettering
2016-04-25sd-journal: add logic to open journal files of a specific OS treeLennart Poettering
With this change a new flag SD_JOURNAL_OS_ROOT is introduced. If specified while opening the journal with the per-directory calls (specifically: sd_journal_open_directory() and sd_journal_open_directory_fd()) the passed directory is assumed to be the root directory of an OS tree, and the journal files are searched for in /var/log/journal, /run/log/journal relative to it. This is useful to allow usage of sd-journal on file descriptors returned by the OpenRootDirectory() call of machined.
2016-04-25machined: add new OpenRootDirectory() call to Machine objectsLennart Poettering
This new call returns a file descriptor for the root directory of a container. This file descriptor may then be used to access the rest of the container's file system, via openat() and similar calls. Since the file descriptor returned is for the file system namespace inside of the container it may be used to access all files of the container exactly the way the container itself would see them. This is particularly useful for containers run directly from loopback media, for example via systemd-nspawn's --image= switch. It also provides access to directories such as /run of a container that are normally not accessible to the outside of a container. This replaces PR #2870. Fixes: #2870
2016-04-25sd-journal: add API for opening journal files or directories by fdLennart Poettering
Also, expose this via the "journalctl --file=-" syntax for STDIN. This feature remains undocumented though, as it is probably not too useful in real-life as this still requires fds that support mmaping and seeking, i.e. does not work for pipes, for which reading from STDIN is most commonly used.

2016-04-25journalctl: improve error message when we have trouble reading journal filesLennart Poettering
Let's output the actual error code encountered, and let's not claim this was purely triggered by files, because it can also be triggered by directories.
2016-04-25sd-journal: properly collect errors from readdir()Lennart Poettering
Let's also collect errors returned by readdir() into our set of errors, like we do this for all other errors from journal files.
2016-04-25journal: add inotify watches by-fd instead of by-pathLennart Poettering
This is slightly nicer, since we actually watch the directories we opened and enumerate. However, primarily this is preparation for adding support for opening journal files by fd without specifying any path, to be added in a later commit.

It make more sense to initalize the node first then we add to the list.

2016-04-22journal-remote : Ensure reallocation of source->buf does not result in ↵Klearchos Chaloulos
source->size < source->filled (#3086) While the function journal-remote-parse.c:get_line() enforces an assertion that source->filled <= source->size, in function journal-remote-parse.c:process_source() there is a chance that source->size will be decreased to a lower value than source->filled, when source->buf is reallocated. Therefore a check is added that ensures that source->buf is reallocated only when source->filled is smaller than target / 2.

2016-04-22core: don't dispatch load queue when setting Slice= for transient unitsLennart Poettering
Let's be more careful when setting up the Slice= property of transient units: let's use manager_load_unit_prepare() instead of manager_load_unit(), so that the load queue isn't dispatched right away, because our own transient unit is in it, and we don#t want to have it loaded until we finished initializing it.

2016-04-22coredump,basic: generalize O_TMPFILE handling a bitLennart Poettering
This moves the O_TMPFILE handling from the coredumping code into common library code, and generalizes it as open_tmpfile_linkable() + link_tmpfile(). The existing open_tmpfile() function (which creates an unlinked temporary file that cannot be linked into the fs) is renamed to open_tmpfile_unlinkable(), to make the distinction clear. Thus, code may now choose between: a) open_tmpfile_linkable() + link_tmpfile() b) open_tmpfile_unlinkable() Depending on whether they want a file that may be linked back into the fs later on or not. In a later commit we should probably convert fopen_temporary() to make use of open_tmpfile_linkable(). Followup for: #3065

2016-04-22tree-wide: don't assume CLOCK_BOOTIME is generally availableLennart Poettering
Before we invoke now(CLOCK_BOOTTIME), let's make sure we actually have that clock, since now() will otherwise hit an assert. Specifically, let's refuse CLOCK_BOOTTIME early in sd-event if the kernel doesn't actually support it. This is a follow-up for #3037, and specifically: https://github.com/systemd/systemd/pull/3037#issuecomment-210199167
