Subject: Abusing region 0
Date: Thu, 03 Feb 2005 01:03:01 +0000 [thread overview]
Message-ID: <42017845.9080507@free.fr> (raw)
I am going to do some experiments: I am going to map some of the
virtual address ranges of a process into the address space of another
one. They are real 64 bit processes, i.e. the region 0 is not used.
Can I abuse this region 0 for mapping the addresses of the neighbor
process into this region ? E.g. if process A has got an address at
0x6000000000001000, then I am going to map it for B at address
0x0000000000001000 ? Wont anything break ?
(I need this trick because the source address can correspond to
anything, like initialized data, BSS, anonymous allocation, etc, i.e.
some SHM just wont work.)
Any advice will be appreciated.
