* useracc() the prequel:Poul-Henning Kamp1999-10-291-1/+0
| | | | | | | | | | | | | | Merge the contents (less some trivial bordering the silly comments) of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>. This puts the #defines for the vm_inherit_t and vm_prot_t types next to their typedefs. This paves the road for the commit to follow shortly: change useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE} as argument. Notes: svn path=/head/; revision=52635

| | | | | | | | | | /sys/ddb/db_input.c rev 1.19 to recognize syscons's cursor keycodes. It is unnecessary now that scgetc() in syscons returns the escape sequence for the cursor keys rather than their raw, internal key codes. Notes: svn path=/head/; revision=48810

* Examine all occurrences of sprintf(), strcat(), and str[n]cpy()Archie Cobbs1998-12-041-4/+2
| | | | | | | | | | | | | | | | | for possible buffer overflow problems. Replaced most sprintf()'s with snprintf(); for others cases, added terminating NUL bytes where appropriate, replaced constants like "16" with sizeof(), etc. These changes include several bug fixes, but most changes are for maintainability's sake. Any instance where it wasn't "immediately obvious" that a buffer overflow could not occur was made safer.

| | | | | | | | | | get to all the symbol tables for all modules, not just the core kernel symbol table. Yes, DDB can see KLD module symbols with this, both by lookup and in tracebacks. No more references to _end from tracebacks within an LKM. :-) Notes: svn path=/head/; revision=40151
* At the moment, the alpha tentatively uses the ddb elf code rather than KLD,Peter Wemm1998-10-091-10/+4
| | | | | | | | | | because the alpha boot loader hasn't been converted yet, and because it needs the full symbol tables with local symbols in order to make sense of stack tracebacks. KLD will implement this (using full sybmol table rather than the globals only) shortly. Notes: svn path=/head/; revision=40150

* Added macros __printflike() and __scanflike() to <sys/cdefs.h>.Bruce Evans1998-07-131-4/+3
| | | | | | | | | | | Use them to `make gcc -Wformat' check formats for all printf-like and scanf-like functions in /usr/src except for the err()/warn() family. err() isn't quite printf-like since its format arg can legitimately be NULL. syslog() isn't quite printf-like, but gcc already accepts %m, even for plain printf() when it shouldn't.

I decided not to change the arg type for %n from [unsigned] int to register_t, since about half of the uses of %n are to print plain ints and casting to [unsigned] long for %n is no harder than for %x.

| | | | | | | | | | | | | FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change.

* Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.Poul-Henning Kamp1998-05-281-27/+1
| | | | | | | | | | | | | | | | | | | | | | | Clean up (or if antipodic: down) some of the msgbuf stuff. Use an inline function rather than a macro for timecounter delta. Maintain process "on-cpu" time as 64 bits of microseconds to avoid needless second rollover overhead. Avoid calling microuptime the second time in mi_switch() if we do not pass through _idle in cpu_switch() This should reduce our context-switch overhead a bit, in particular on pre-P5 and SMP systems.
