* Be more careful when dumping cmsghdr struct. In the SCM_RIGHTS case anclaudio2018-11-171-2/+4
| | | | | | extra check for a truncated cmsghdr needs to be done since the embeded lenght may be longer than the supplied buffer (MSG_CTRUNC case). OK deraadt@

* Unveiling unveil(2).beck2018-07-131-1/+5
| | | | | | | | | | | | | This brings unveil into the tree, disabled by default - Currently this will return EPERM on all attempts to use it until we are fully certain it is ready for people to start using, but this now allows for others to do more tweaking and experimentation. Still needs to send the unveil's across forks and execs before fully enabling. Many thanks to robert@ and deraadt@ for extensive testing. ok deraadt@
* pledge()'s 2nd argument becomes char *execpromises, which becomes thederaadt2017-12-121-6/+6
| | | | | | | | | | pledge for a new execve image immediately upon start. Also introduces "error" which makes violations return -1 ENOSYS instead of killing the program ("error" may not be handed to a setuid/setgid program, which may be missing/ignoring syscall return values and would continue with inconsistant state) Discussion with many florian has used this to improve the strictness of a daemon

* add a hack to avoid printing the long string format for times in the 70s.tedu2016-06-071-2/+3
| | | | | | this is usually a result of a timestamp which hasn't been identified as "relative" and decoding them to precise dates long in the past is a distraction. (eagerly awaiting a cleaner, better diff to do the same.)
* On hppa, function pointer comparison can require dereferencing them.guenther2016-05-221-3/+9
| | | | | | | kdump can't do that for a sigaction sa_handler pointer from the trace, so cast to void* to suppress it. ok deraadt@

| | | | | | | | | VIS_CSTYLE | VIS_DQ | VIS_TAB | VIS_NL; add the latter three flags to the existing vis encoding of exec argv/environ and pledge requests/paths. Delete local variables left unused when showbuf() and showbufc() were split ok otto@ millert@

* Display struct event more like other structs: show all members and use cppguenther2016-01-141-42/+15
| | | | | | | | | | define names. Use the mksubr infrastructure for EVFILT_*, EV_*, and (with some kludging) NOTE_* values. If EV_ERROR is set, include the errno string for the data member. Also, do MSG_* parsing on the msg_flags member of struct msghdr. ok millert@
