* Avoid the "Cannot allocate memory" problem that appears on heavilydes1998-10-121-4/+10
| | | | | | | | | loaded systems by retrying the sysctl() with a larger buffer if it fails with ENOMEM. For good measure, allocate 10% more memory than sysctl() claims is necessary. PR: 8275 Reviewed by: David Greenman <dg@freebsd.org>

* Replace memory leaking instances of realloc with non-leaking reallocf.imp1998-09-161-1/+3
| | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

| | | | | | | | | | | | are in kvm_uread(): - the setting of errno before checking it in the lseek() was lost. - EOF handling was lost. kvm_uread() retried forever on EOF. EOF is not really an error, but report it one as in rev.1.2. - reporting of errno after a read error was lost. Fixed style bugs in rev.1.3 and rev.1.12. Not fixed: errno is not reported after lseek() failures.

| | | | | | | | | | | | dead kernel debugging. The previous code was a "do nothing". The most obvious side effect of this is that you can now do things like this and reasonably expect them to work: dmesg -M /var/crash/vmcore.3 -N /var/crash/kernel.3 ps -axl -M /var/crash/vmcore.3 -N /var/crash/kernel.3 A good deal of this was lifted from the gdb code to do this, as well as from NetBSD's libkvm (which has completely different VM macros)
