* Delete the final, inscrutable NOSTRICT and VARARGS lint commentsguenther2015-09-291-2/+1
| | | | ok millert@
* Remove some includes include-what-you-use claims don'tjsg2015-03-141-2/+1
| | | | | | | have any direct symbols used. Tested for indirect use by compiling amd64/i386/sparc64 kernels. ok tedu@ deraadt@

* KASSERTMSG(9): New kernel assertion with messageuebayasi2014-07-131-3/+2
| | | | | | | | | | | | | | | | | | | | | | | KASSERT() is annoying as it only prints the expression as a string. If you (developers) want to know a little more information, you have to do: #ifdef DIAGNOSTIC if (bad) panic(...); #endif KASSERTMSG() replaces it into a single line: KASSERTMSG(!bad, ...); Taken from NetBSD. (There is a concern that KASSERT() messages are too long; consume more memory, and not friendly for small monitors. This have to be considered & revisited later.) "Like" from henning@ Man page review & advices from jmc@ and schwarze@
* reboot(9): Add MI reboot entry functionuebayasi2014-07-111-2/+3
| | | | | | | | Now, for kernel to "reboot" (reboot, halt, or shutdown), MD boot(9) is called in some places. This change introduces a new MI function reboot(9) which is simply a wrapper to call MD boot(9). OK kettenis@ deraadt@
* Add db_vprintf(), and then use it in ACPI's db_disprint() instead ofguenther2013-12-121-6/+13
| | | | | | formatting into a local buffer. ok miod@
* disable %n in printf(9); there is no need for it in the kernel besidesdjm2013-11-251-6/+7
| | | | | making format-string vulnerabilities exploitable; inspired by similar change made by Kees Cook to Linux; ok deraadt@
* After a panic, do not fill up the dmesg with splassert messages.bluhm2013-08-071-1/+4
| | | | | | They scroll away the important information. Disable splassert in panic(). OK deraadt@ uebayasi@ sthen@
* add support for %td for ptrdiff_t in kernel printfsf2013-07-031-1/+4
| | | | | | this also adds support in gcc 4.x kprintf format checks ok kettenis@
* do not include machine/cpu.h from a .c file; it is the responsibility ofderaadt2013-03-281-2/+1
| | | | | .h files to pull it in, if needed ok tedu
* Allow kernel printfs to go to console if in ddb instead of being redirecteddrahn2011-04-031-3/+14
| | | | to xconsole. ok deraadt@ guenther@
* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-7/+9
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots
* Do not disallow kernel crash dumps on panic if swap encryption is enabled,miod2008-06-271-8/+1

| | | | | | size_t and ssize_t variables. OK miod and cthulhu.
* Remove support for ddb-only %r, %z, and the ddb-specific handling of %n frommiod2007-09-011-66/+2
| | | | the kernel printf. This will allow support for the real %z in the near future.

* Stuff needed for gcc 3.X.art2002-10-141-9/+38
| | | | | | | | | | | | | | gcc has the nice feature of optimizing various common constructs into more optimal ones, inlining various calls, etc. The problem with that is that it assumes that we have a proper libc backing us. We really don't want to loose all those features by defining -ffreestanding and right now there is no way to just disable some of them, so we have to make the kernel more libc-like in some aspects to make it work with newer gcc. rename putchar to kputchar because it was nothing like libc putchar (and only internal to this function). Implement dummy putchar and puts (not prototyped outside this file).
* Add one more level to the kern.splassert sysctl.art2002-05-201-4/+8
| | | | | | | | 0 - do nothing. 1 - small message on error (function name and the levels). 2 - big message on error (function name, levels and traceback (if possible)). 3 - panic. After suggestion from deraadt@.
