2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-26util-lib: split out user/group/uid/gid calls into user-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-08-24core: optionally create LOGIN_PROCESS or USER_PROCESS utmp entriesLennart Poettering
When generating utmp/wtmp entries, optionally add both LOGIN_PROCESS and INIT_PROCESS entries or even all three of LOGIN_PROCESS, INIT_PROCESS and USER_PROCESS entries, instead of just a single INIT_PROCESS entry. With this change systemd may be used to not only invoke a getty directly in a SysV-compliant way but alternatively also a login(1) implementation or even forego getty and login entirely, and invoke arbitrary shells in a way that they appear in who(1) or w(1). This is preparation for a later commit that adds a "machinectl shell" operation to invoke a shell in a container, in a way that is compatible with who(1) and w(1).

2015-04-24shared/utmp-wtmp: add parameter for origin tty and callback userdataDaniel Mack
Instead of looking up the tty from STDIN, let utmp_wall() take an argument to specify an origin tty for the wall message. Only if that argument is NULL do the STDIN lookup. Also add an void *userdata argument that is handed back to the callback function.

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.
2014-09-19shared: wtmp-utmp - don't clear store_wtmp in utmp_put_dead_process()Tom Gundersen
Also modernize a few other things and add comments to explain CID #1237503 and CID #1237504.
2014-03-14utmp-wtmp: allow overriding username on wallSebastian Thorarensen
utmp_wall() now takes an optional argument 'username_override' which allows the caller to override the username shown on wall messages. journald will use this to inform users that its wall messages comes from 'systemd-journald'.
2014-01-30utmp: make sure we don't write the utmp reboot record twice on each bootLennart Poettering
(Also, only send the audit msg once, too)
2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.
2013-05-02Add __attribute__((const, pure, format)) in various placesZbigniew Jędrzejewski-Szmek
I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.

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.
2013-03-31ModernizationZbigniew Jędrzejewski-Szmek
Use _cleanup_ and wrap lines to ~80 chars and such.

Based on coverity report.

2013-03-28utmp-wtmp: don't try to read past end of stringZbigniew Jędrzejewski-Szmek
systemd-199/src/shared/utmp-wtmp.c:228: buffer_size_warning: Calling strncpy with a maximum size argument of 32 bytes on destination array "store.ut_line" of size 32 bytes might leave the destination string unterminated. The destination string is unterminated on purpose, but we must remember that.
