2017-02-02logind: Don't try to emit a change signal for the 'Sessions' property (#5211)afrantzis
The 'Sessions' property for both org.freedesktop.login1.User and org.freedesktop.login1.Seat is marked as EmitsChangedSignal(false). Trying to emit a change signal that includes the 'Sessions' property leads to the signal not being sent at all. Fixes #5210.
2016-11-07Rename formats-util.h to format-util.hZbigniew Jędrzejewski-Szmek
We don't have plural in the name of any other -util files and this inconsistency trips me up every time I try to type this file name from memory. "formats-util" is even hard to pronounce.

2016-07-20logind: always abandon session scopes before killing themLennart Poettering
This way systemd is informed that we consider everything inside the scope as "left-over", and systemd can log about killing it. With this change systemd will log about all processes killed due to the session clean-up on KillUserProcesses=yes.

Desktop environments can keep this property up to date to allow applications to easily track session's Lock status.
2016-05-05logind: process session/inhibitor fds at higher priorityLennart Poettering
Let's make sure we process session and inhibitor pipe fds (that signal sessions/inhibtors going away) at a higher priority than new bus calls that might create new sessions or inhibitors. This helps ensuring that the number of open sessions stays minimal.

This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

Sort the includes accoding to the new coding style.
2015-11-13logind: add a new UserTasksMax= setting to logind.confLennart Poettering
This new setting configures the TasksMax= field for the slice objects we create for each user. This alters logind to create the slice unit as transient unit explicitly instead of relying on implicit generation of slice units by simply starting them. This also enables us to set a friendly description for slice units that way.
2015-11-13logind: don't assert if the slice is missingLennart Poettering
After all, we don't actually really need the slice to work, it's just nice to have it.
2015-11-05treewide: use the negative error codes returned by our functionsMichal Schmidt
Our functions return negative error codes. Do not rely on errno being set after calling our own functions.

2015-10-27src/basic: rename audit.[ch] → audit-util.[ch] and capability.[ch] → ↵Lennart Poettering
capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.

2015-09-09tree-wide: make use of log_error_errno() return value in more casesLennart Poettering
The previous coccinelle semantic patch that improved usage of log_error_errno()'s return value, only looked for log_error_errno() invocations with a single parameter after the error parameter. Update the patch to handle arbitrary numbers of additional arguments.
2015-09-09tree-wide: use coccinelle to patch a lot of code to use mfree()Lennart Poettering
This replaces this: free(p); p = NULL; by this: p = mfree(p); Change generated using coccinelle. Semantic patch is added to the sources.
2015-08-18logind: get a fresh file descriptor to clean up a VTOwen W. Taylor
When the controlling process exits, any existing file descriptors for that FD will be marked as hung-up and ioctls on them will file with EIO. To work around this, open a new file descriptor for the VT we want to clean up. Thanks to Ray Strode for help in sorting out the problem and coming up with a fix! https://github.com/systemd/systemd/issues/989
2015-08-18logind: use open_terminal() instead of open()Owen W. Taylor
The open_terminal() function adds retries in case a terminal is in the process of being closed when we open it, and should generally be used to open a terminal. We especially need it for code that a subsequent commit adds that reopens the terminal at session shut-down time; such races would be more likely in that case. Found by Ray Strode.
2015-08-06logind,machined: various smaller cleanupsLennart Poettering
Use mfree() where we can. Drop unnecessary {}. Drop unnecessary variable declarations. Cast syscall invocations where explicitly don't care for the return value to (void). Reword a comment.
2015-08-05logind: switch to sd_bus_track helperDaniel Mack
Let logind use the sd_bus_track helper object to track the controllers of sessions. This does not only remove quite some code but also kills the unconditional matches for all NameOwnerChanged signals. The latter is something we should never ever do, as it wakes up the daemon every time a client connects, which doesn't scale.
2015-07-31logind: release VT-positions when closing sessionsDavid Herrmann
Make sure we release VT-positions when a session is closed. Otherwise, lingering sessions will occupy VTs and prevent next logins from succeeding. Note that we already release session-devices when closing a session, so there cannot be anyone using the VT anymore.
2015-07-29tree-wide: port everything over to fflush_and_check()Lennart Poettering
Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
2015-07-10logind: rename 'pos' to 'position'David Herrmann
Spell out the proper name. Use 'pos' over 'position', and also update the logind state file to do the same. Note that this breaks live updates. However, we only save 'POSITION' on non-seat0, so this shouldn't bother anyone for real. If you run multi-seat setups, you better restart a machine on updates, anyway.

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.
2015-01-28logind: handle closing sessions over daemon restartsMartin Pitt
It may happen that you have several sessions with the same VT: - Open a session c1 which leaves some processes around, and log out. The session will stay in State=closing and become Active=no. - Log back in on the same VT, get a new session "c2" which is State=active and Active=yes. When restarting logind after that, the first session that matches the current VT becomes Active=yes, which will be c1; c2 thus is Active=no and does not get the usual polkit/device ACL privileges. Restore the "closing" state in session_load(), to avoid treating all restored sessions as State=active. In seat_active_vt_changed(), prefer active sessions over closing ones if more than one session matches the current VT. Finally, fix the confusing comment in session_load() and explain it a bit better. https://launchpad.net/bugs/1415104

2014-11-28treewide: another round of simplificationsMichal Schmidt
Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
