* Allocate KSEs and KSEGRPs separatly and remove them from the proc structure.Julian Elischer2002-09-151-12/+45
| | | | | | | | | | | | next step is to allow > 1 to be allocated per process. This would give multi-processor threads. (when the rest of the infrastructure is in place) While doing this I noticed libkvm and sys/kern/kern_proc.c:fill_kinfo_proc are diverging more than they should.. corrective action needed soon.

* Fix (for the second time) kvm_getprocs() for the case where noDima Dorfman2002-04-071-0/+26
| | | | | | | | | | | | | | | processes match the given criteria. Since revision 1.60 of malloc.c, malloc() and friends return an invalid pointer when given a size of 0. kvm_getprocs() uses sysctl() with a NULL oldp argument to get an initial size, but does not check whether it's 0 before passing it to realloc() (via _kvm_realloc()). Before the aforementioned malloc() change, this resulted in a minimal allocation made and a valid poitner returned, but now results in an invalid, but non-NULL, pointer being returned. When this is passed to sysctl(), the latter returns EFAULT (as it should). Notes: svn path=/head/; revision=94028
