pjd 2006-01-31 11:09:22 UTC FreeBSD src repository Modified files: sys/kern kern_malloc.c share/man/man9 Makefile sys/conf NOTES files options Added files: share/man/man9 redzone.9 sys/vm redzone.c redzone.h Log: Add buffer corruption protection (RedZone) for kernel's malloc(9). It detects both: buffer underflows and buffer overflows bugs at runtime (on free(9) and realloc(9)) and prints backtraces from where memory was allocated and from where it was freed.
