* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-22/+22
| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

* From a syslog perspective it does not make sense to log fatal andbluhm2017-03-211-6/+6
| | | | | | warn with the same severity. Switch log_warn() to LOG_ERR and keep fatal() at LOG_CRIT. OK reyk@ florian@

* Add a -u switch to always log route insertions/deletions.jca2016-08-052-9/+26
| | | | | | | | Route updates (and associated warnings) are always prefixed with "RTADD" or "RTDEL". This is useful for people that previously used the -R option that got removed. Tested by Freddy Dissaux.
* Use tighter pledge(2) restrictions.jca2016-08-051-2/+2
| | | | Made possible by the logging overhaul. Tested by Freddy Dissaux.
* Rework logging.jca2016-08-055-339/+426
| | | | | | | | | | | | Use log.c like in many other daemons, with small additions to maintain a log queue (useful to dump a single log line with several logging statements). Use log.c to dump the internal state, and remove the -R option (a similar feature will be implemented differently soon). The end goal is to avoid touching the filesystem and use much tighter pledge(2) restrictions. Tested by Freddy Dissaux.
* Introduce RTF_MULTICAST and flag corresponding IPv6 routes as suchmpi2016-07-131-31/+2
| | | | | | instead of abusing RTF_CLONING. Fix a leak reporeted by Aaron Riekenberg on misc@, ok sthen@
* route6d spring cleanupjca2016-07-061-23/+7
| | | | | | | | | | | | | | Various tweaks and fixes: - nuke util.h, not needed since pidfile(3) went away - nuke the rrt_same member of struct riprt, "future use" since import - mark rtdexit as __dead - nuke progname handling - fix pid handling: cache the pid *after* calling daemon(3) - nuke setting rtm_pid. The kernel is responsible for setting this in routing messages. - nuke the useless myseq variable ok florian@ benno@ millert@ deraadt@ renato@

* Rename the struct pollfd array, "set" -> "pfd"jca2015-10-261-10/+10
| | | | | "set" reminds of select(2) fd_set, and is never used elsewhere in the tree as a name for a pollfd array. No functional change.
* Those variables should be local to the functions where they are used.jca2015-10-261-12/+11

| | | | No functional change.
* Kill unused ROUTE6D_CONF define.jca2015-10-251-5/+1
| | | | Since 1999 no one has found the need to write support for a config file.
* Another pidfile(3) removal; ok benno@jca2015-10-252-6/+2

* Tweak previous: call fatal(), not err(3), for consistency. err.h goes away.jca2015-10-181-3/+2

* Unbreak route6d.jca2015-10-161-4/+4
| | | | | | | | | | | Instead of breaking sendmsg(2) by adding unneeded space to its cmsg item, add space to the cmsg used by recvmsg(2), where it will be used to get the incoming packet hop limit. Reported by several over the last years, and more recently by 'bsdsx', who tested it against NetBSD route6d. Also works against Quagga ripng. ok deraadt@ sthen@

| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
