* Fixed a misspelling of 0 as NULL.Bruce Evans2004-03-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed a nearby bug. The "play it safe" code in dosysctl() was unsafe because it overran the buffer by 1 if sysctl() filled all of the buffer. Fixed a nearby style bug in output. Not just 1, but 2 extra newlines were printed at the end by "vmstat -m" and "vmstat -z". Don't print any newlines explicitly. This depends on 2 of the many formatting bugs in the corresponding sysctls. First, the sysctls return an extra newline at the end of the strings. This also messes up output from sysctl(8). Second, the sysctls return an extra newline at the beginning of the strings. This is good for separating the 2 tables output by "vmstat -mz" and for starting the header on a new line in plain sysctl output, but gives a bogus extra newline at the beginning for "vm -[m | z]" and "sysctl -n [kern.malloc | vm.zone]". Fixed some nearby style bugs in the source code: - the same line that misspelled 0 as NULL also spelled NULL as 0. - the size was doubled twice in the realloc loop. - the "play it safe" comment was misleading. Terminating the buffer is bogus because dosysctl() is only meant to work with sysctls that return strings and the terminator is part of a string. However, the kern.malloc sysctl has more than style bugs. It also doesn't return a string. Termination is needed to work around this bug. Notes: svn path=/head/; revision=126842

* Fix a couple of issues in the interrupt code:Dag-Erling Smørgrav2003-12-101-21/+13
| | | | | | | | | | | | | | | | | | - Replace overly-complicated (and buggy) -a logic with a much simpler version: -a causes all interrupts to be displayed, otherwise only those that have occurred are displayed. This removes the need for any MD code. - Instead of just making sure intrcnt is large enough, figure out the exact size it needs to be. We derive nintr from this number, and we don't want to risk printing garbage. Note that on sparc64, we end up printing garbage anyway because the names of non-existent interrupts are left uninitialized by the kernel.
