cleanup: delete remains of libutil

2020-03-31T16:19:27+00:00

- exec_t belongs to service.h, the main place where it is used/needed - code for executing exec_t is moved to runsvc for the same reason - what is left are NORETURN and ARRAY_SIZE - the former can be replaced with direct attribute usage since the only relevant compilers all support the attribute. - the later is only used in 3 places and can be trivially replaced with direct usage of sizeof().

cleanup runsvc: merge codepaths for execution, remove cleanup code

2019-03-20T14:09:35+00:00

Simply execute the last entry in the list directly instead of forking and remove the cleanup code. If the list is empty, we return success. If the list only has one entry, we directly execute that. No need to make a distinction between single entry vs list anymore. If the list is an actual list, we run it as before but execute the last one directly. Typically, the last one is something like a daemon preceeded by setup code. The daemon ends up directly underneath init, without a dummy waiting runsvc stuck in the process list. If we always do an exec, there is no point in doing cleanup. All our mapped memory is evicted anyway. Same if we exit appruptly because of an error. Signed-off-by: David Oberhollenzer

Configuration parser cleanup

2018-10-10T14:45:11+00:00

- Do a getline() & process in rdline instead of doing a read per character and feeding it through a state machine. - Move splitkv to rdcfg.c, the only place where it is used Signed-off-by: David Oberhollenzer

Add output truncation flag

2018-07-22T15:57:20+00:00

This commit adds a "truncate" flag that can be added to a service description between the "tty" keyword and the path string. If the flag is set, the output file is truncated to 0 after opening. This probably requires some remodeling in the future as the tty keyword no longer deals with just tty devices. Signed-off-by: David Oberhollenzer

Add helper program for running services

2018-04-22T11:41:18+00:00

We no longer need to keep entire scripts in init program (i.e. saving space) and reduce the code and complexity of the init program. The runsvc tool can later be extended to do more complex child setup, such as configuring namespaces or seccomp without adding complexity or memory footprint to init.
