This patch-set aims at removing the current limit on argv+env space aka. MAX_ARG_PAGES.
The new mm is created before the binfmt code runs, the stack is placed at the highest address supported by that architecture. The argv+env data is then copied from the old mm into the new mm (which is inactive at that time - this introduces some cache coherency issues). Then we run the binfmt code, which will compute the final stack address. The existing stack will be moved downwards (or upwards on PA-RISC) to the desired place. This 'trick' heavily relies on the MMU, so for no-MMU archs we stay with the old approach. Tested-on: i386, ia64, frv, parisc, ppc64, um, x86_64 Patches against: .22-rc4 -- Changes since last time: - fixed ia64 ( va-space constraints ) - fixed ia64 CONFIG_IA32_SUPPORT ( brown paper bags and more va-space constraints) - fixed powerpc ( address limit on stack extention ) - removed audit_kill() in favour of audit_panic() - nicely spit out the patches - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
