Greetings! It seems that we are in need of a 'big usermem' kernel patch in Debian, so I am considering contributing such a package. It appears there are two approaches on the net, both in various incarnations of redhat:
1) user-tunable /proc/self/mapped_base -- this allows setuid processes to move the base address at which shared libs are mapped from the default (on x86) of 0x40000000, allowing for much larger contiguous brk *or* mmaped space (up to 2.7 GB -- the oracle docs appear to refer to this. See also WOLK). 2) In RHEL3, the kernel maps PROT_EXEC maps below the executable, and other maps down from the stack, giving an undivided brk/mmap area. this seems best, but I can't yet find the RH patch anywhere. (See RH bugzilla 104583). Ideas? I'm looking to allow users procs in Debian to allocate the largest continuous block possible, either through brk or mmap (at the user's choice).
