Hi!
I'm working with mmap and mprotect functions. After I mmaped a region that contain some memory pages, I give a read-only permission to one of the pages. When I try to write on this read-only page, no signal is generated. This same program, running on a SunOs system, generate a SIGSEGV signal and on a FreeBSD system a SIGBUS signal. Looking at man I have founded a SIGBUS is missing. And from kernel version 2.0.24 until version 2.1.20, no signal SIGBUS or SIGSEGV is generated. Please send any hints and comments.
Thanks in advance,
Mario
