2020-03-25init(8): use err(3) instead of hand-rolled fprintf(3) messagescheloha1-9/+5
2019-06-28When system calls indicate an error they return -1, not some arbitraryderaadt1-4/+4
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.
2018-08-24Drop special handling of SIGSYS.cheloha1-20/+2
Tolerance for up to 25 SIGSYS deliveries was added to init(8) soon after the addition of sysctl(2) at CSRG, presumably to ease the transition to the new ABI. After 25 years of work the ABI transition is finally complete and we can now safely remove this splint. In general, we now have better practices and methods for helping userspace across kernel ABI breaks. ok deraadt@
2018-01-31Check GETTY_SPACING against the monotonic clock.cheloha1-10/+14
Ensures that we can use the check if the system clock is set backwards. While here, move time retrieval into the child process in start_getty(), and only get the time if se_started has been set. ok millert@ tb@

2017-05-03Use the safe idiom of cleaning sensitive data from memory with explicit_bzero,mestre1-3/+4
instead of relying on other methods, after readpassphrase. Some programs on this diff won't benefit that much since it happens near the terminal path, but someone might copy the unsafe idiom to another program and place it where it may leak sensitive data. Discussed aeons ago with tb@, OK deraadt@ and beck@
2017-03-02Add a new sysctl machdep.lidaction. The sysctl works as follows:natano1-6/+6
machdep.lidaction=0 # do nothing machdep.lidaction=1 # suspend machdep.lidaction=2 # hibernate lidsuspend is just an alias for lidaction, so if you change one, the other one will have the same value. The plan is to remove machdep.lidsuspend eventually when people have upgraded their /ets/sysctl.conf. discussed with deraadt, who came up with the new MIB name no objections mlarkin ok stsp halex jcs

2015-09-25there's no need to keep init secret these days, and the (unused)tedu1-3/+1
immutable flags would just be a pita. remove custom bin mode.

2015-07-14Use volatile sig_atomic_t for requested_transition since it ismillert1-61/+82
modified inside signal handlers. Instead of returning a function pointer, the state functions now return an enum for the next state. This is used as an index into an array of function pointers to do the actual state change in transition(). OK deraadt@

2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt1-4/+4
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. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2014-01-03Do not raise the securelevel when transitioning from catatonia tomillert1-5/+7
multiuser since we are not actually going multiuser. Fixes a problem where the securelevel was raised for rc.shutdown even when reboot was run from single user mode. OK deraadt@
2013-02-11Ignore sysctl failure for CPU_LIDSUSPEND when errno is EOPNOTSUPP.millert1-2/+2
Just because CPU_LIDSUSPEND is defined in cpu.h does mean it is actually supported by the hardware. OK halex@
2012-10-11fix "disable lidsuspend on shutdown":halex1-3/+3
- pull in machine/cpu.h so we can actually see CPU_LIDSUSPEND if it's there - fix the resulting compilation errors now that the code is actually used "Just go for it" deraadt@

2011-05-10Some cleanup and simplifications:schwarze1-24/+32
- Explain single user mode once, not three times. - Do not claim that the boot program talked to init; it cannot do so. - Mention that the OpenBSD kernel does not support init -f. - And some minor rewordings and reorderings. Feedback and ok jmc@.
