I had to modify the file monitor_mm.c to get the privledge separation to work for Linux 2.0.36 (and above) and am passing on the patch to you; if there is a better place to send this, please let me know.

Linux 2.2 (and probably others) have a deficient mmap which has caused a number of problems (e.g. bug #285). A workaround is in development, but it would be helpful to have a configure test to detect the bad mmaps(). Any takers? -d

i think our strategy for privsep is to just keep portable sync'd closely with openbsd's tree, even though things will be broken wrt privsep for many platforms. then we just get primary one's working and work out issues as we go along. i'll start to work on sun and hp-ux again tomorrow.

...n MAP_ANON is set in flags, and fd is set to -1, mmap() provides a direct path to return anonymous pages to the caller. This operation is equivalent to passing mmap() an open file descriptor on /dev/zero with MAP_ANON elided from the flags argument. Thus, I suppose in monitor_mm.c (of 3.3p1), the lines 88-89 address = mmap(NULL, size, PROT_WRITE|PROT_READ, MAP_ANON|MAP_SHARED, -1, 0); could be replaced by { static int mmfd = -1; if(mmfd < 0) mmfd = open("/dev/zero", O_RDWR); address = mmap(NULL, size, PROT_WRITE|PROT_READ, MAP_SHARED,...
