* brk randomization: introduce CONFIG_COMPAT_BRKIngo Molnar2008-02-063-2/+25
| | | | | | | | | | | | based on similar patch from: Pavel Machek <pavel@ucw.cz> Introduce CONFIG_COMPAT_BRK. If disabled then the kernel is free (but not obliged to) randomize the brk area. Heap randomization breaks ancient binaries, so we keep COMPAT_BRK enabled by default. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* brk: check the lower bound properlyJiri Kosina2008-02-061-1/+1
| | | | | | | | | | | | | There is a check in sys_brk(), that tries to make sure that we do not underflow the area that is dedicated to brk heap. The check is however wrong, as it assumes that brk area starts immediately after the end of the code (+bss), which is wrong for example in environments with randomized brk start. The proper way is to check whether the address is not below the start_brk address. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove X2 workaroundIngo Molnar2008-02-061-11/+0

* x86: make spurious fault handler aware of large mappingsThomas Gleixner2008-02-061-6/+17
| | | | | | | | | | | | | In very rare cases, on certain CPUs, we could end up in the spurious fault handler and ignore a large pud/pmd mapping. The resulting pte pointer points into the mapped physical space and dereferencing it will fault recursively. Make the code aware of large mappings and do the permission check on the pmd/pud entry, when a large pud/pmd mapping is detected.

* x86: make traps on entry code be debuggable in user space, 64-bitRoland McGrath2008-02-061-6/+15
| | | | | | | | | | | | Unify the x86-64 behavior for 32-bit processes that set bogus %cs/%ss values (the only ones that can fault in iret) match what the native i386 behavior is.

The commit 139ddfcab50e5eabcc88341c8743a990ac1be6a2 ("ide: move handling of I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe check vs ide_hwif_request_regions() call (so that we now reserve I/O regions before checking for hwif->noprobe). However ide-generic host driver depended on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots. Fix it by passing only indexes of non-empty slots to ide_device_add_all() from ide_generic_init(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation simply refused to allocate more than a boundary's worth of data from an entire page. Some users didn't know this, so specified things like SMP_CACHE_BYTES, not realising the horrible waste of memory that this was. It's fairly easy to correct this problem, just by ensuring we don't cross a boundary within a page. This even helps drivers like EHCI (which can't cross a 4k boundary) on machines with larger page sizes. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Acked-by: David S.
