* o Introduce kern.security.bsd.unprivileged_read_msgbuf, which allowsrwatson2001-11-301-0/+13
| | | | | | | | | | | the administrator to restrict access to the kernel message buffer. It defaults to '1', which permits access, but if set to '0', requires that the process making the sysctl() have appropriate privilege. o Note that for this to be effective, access to this data via system logs derived from /dev/klog must also be limited.

Previously only the magic number and the virtual address were checked, but it makes little sense to require that the virtual address is the same (the message buffer is located at the end of physical memory), and checks on the msg_bufx and msg_bufr indices were missing.

* Fixes for a couple of problems in last commit:peter1999-07-101-8/+8
| | | | | | | | | | | | | | | | | 1. Printing large quads in small bases overflowed the buffer if sizeof(u_quad_t) > sizeof(u_long). 2. The sharpflag checks had operator precedence bugs due to excessive parentheses in all the wrong places. 3. The explicit 0L was bogus in the quad_t comparison and useless in the long comparision. 4. There was some more bitrot in the comment about ksprintn(). Our ksprintn() handles bases up to 36 as well as down to 2. Bruce has other complaints about using %q in kernel and would rather we went towards using the C9X style %ll and/or %j. (I agree for that matter, as long as gcc/egcs know how to deal with that.) Submitted by: bde
* Implement the %q prefix for the integer types. Note that egcs on thepeter1999-07-091-17/+81
| | | | | | | Alpha believes that %q is for long long, whereas our quad_t and int64_t is only just a plain long. long long on the alpha is the same size (64 bit) as a long. It was requested, but I have not implemented yet, support for C9X style %lld - it should be pretty easy though.

* Fixed the formatting of some tables (mainly the one produced by psbde1998-08-101-2/+2
| | | | | | | | | | in ddb) which I broke by changing %8[l]x to %8p. Hacked the central printf routine to not add an "0x" prefix for %p formats if the field width is nonzero. The tables are still horribly misformatted on 64-bit machines. Use %p instead of %8p to print pointers when the field width isn't important.
* Cast pointers to uintptr_t/intptr_t instead of to u_long/long,bde1998-07-151-2/+2
| | | | | | | respectively. Most of the longs should probably have been u_longs, but this changes is just to prevent warnings about casts between pointers and integers of different sizes, not to fix poorly chosen types.

| | | | | | | | | | | | | | | (long)(u_long)(u_int)-4 = 0x00000000fffffffc on machines with 32-bit ints and 64-bit longs. Restored %z format for printing signed hex. %+x shouldn't have been used since it is an error in userland. Prepared to nuke %n format by cloning it to %r. %n shouldn't have been used because it means something completely different in userland. Now %+r is equivalent to ddb's original %r, and %r is equivalent to ddb's original %n. Ignore '+' flag in combination with unsigned formats %{o,p,u,x}.
* Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.phk1998-05-281-4/+45
| | | | | | | | | | | | | | | | | | | | 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.
