* Quiet silly clang analyzer warning in calloc() usage.millert2015-11-081-2/+2

* Use __progname instead of the homegrown ProgramName.millert2015-11-065-47/+35

* Change cron from including all headers in every file to only includingmillert2015-11-0417-89/+251
| | | | | what each .c file needs. I have not removed cron.h since it will be used in a future clean up of the cron's .h files. OK nicm@
* Remove unused LogFD variablemillert2015-11-041-6/+1

* Change some globals from extern to static when they are not usedmillert2015-11-046-93/+38
| | | | | outside their respective .c files. Also remove some unused defines. OK jung@
* If pledge(2) fails use perror instead of log_it(RealUser, ...) sincemillert2015-11-031-3/+3
| | | | RealUser has not been filled in yet.
* It is only necessary to swap the effective gid when reading a file.millert2015-11-031-33/+1
| | | | | Since we got rid of TMPDIR support there's no need to swap gids when creating or unlinking the temporary file. OK deraadt@
* Use send(MSG_NOSIGNAL) instead of mucking with the disposition of SIGPIPEguenther2015-11-031-4/+2

* Use setegid() directly instead of swap_gids() / swap_gids_back().millert2015-11-021-33/+25
| | | | OK jca@ nicm@
* Split client-only (at, crontab) functions out of misc.c and intomillert2015-10-314-177/+222
| | | | | client.c. Move truly common functions into common.c. This avoids dead code in the at and crontab commands.
* open_socket() is only used by cron proper so move to cron.cmillert2015-10-313-60/+60

* swap_gids and swap_gids_back are only used by crontab.c somillert2015-10-313-16/+15
| | | | move them there.
* Also need exec to run the editor of course.millert2015-10-291-2/+2
|
* crontab needs "proc" for fork(2)millert2015-10-291-2/+2

* Use stravis(3) instead of a homegrown vis-like function.millert2015-10-293-61/+9
| | | | OK nicm@
* remove unused variablesmillert2015-10-292-4/+3
|
* Convert env_get() into env_find() similar to __findenv() in libc.millert2015-10-293-67/+51
| | | | | Use env_find() in both env_get() and env_set() to find a var in envp. Remove now-unused strcmp_until() function.
* Remove useless FACILITY define and use LOG_CRON directly.millert2015-10-291-12/+2
| | | | Remove unneeded limits.h include.

| | | | ok millert
* Remove TMPDIR support, it is not really useful in crontab.millert2015-10-262-18/+6

* Use SOCK_NONBLOCK and SOCK_CLOEXEC instead of fcntl() calls.millert2015-10-262-19/+6
| | | | OK guenther@
* Remove some useless defines and the set_cron_uid() function.millert2015-10-266-29/+14

* Use ppoll(2) instead of poll(2). This has two benefits. Firstly,millert2015-08-253-32/+34
| | | | | | | we can use struct timespec throughout and avoid any conversion issues which might cause jobs to fire prematurely. Secondly, it eliminates a race condition that could delay us taking action on SIGCHLD and SIGHUP. OK deraadt@ okan@ ratchov@

* Remove the OK and ERR macros. They obfuscate the code and don'ttedu2015-01-239-61/+52
| | | | | | | | | help legibility. (unix system calls use 0 for ok, but hundreds of other projects use 1 to indicate success.) Despite the name, many system calls (e.g., open) also return not OK values for success. It also cleans up some weird code like int crontab_fd = OK - 1; This diff is mechanical in nature. Later I will fix the bugs it reveals. ok deraadt
* minor debug removal cleanuptedu2015-01-232-6/+4
|
* remove debug code.tedu2015-01-2314-368/+23
| | | | | | | | | | I think the level of debug code in cron is excessive for a program that has reached feature complete. If cron needs to provide more information to the user about its operational status, I think syslog would be more appropriate. (The debug flags also disable forking into the background, so they aren't even that useful for debugging a live system.) ok deraadt millert

* use poll() instead of the select malloc/free dance which was used toderaadt2014-10-292-10/+8
| | | | | | | | | | | avoid fd_set overflows. Back when I was young, I fixed these throughout the tree, and the world continued on ignoring the issue... The malloc/free dance was used because poll() was not very portable yet. Now poll() is commonplace, and we should use this safer API. ok guenther millert
