* [PATCH] m32r: security fix of {get,put}_user macrosHirokazu Takata2006-04-115-329/+117Star
| | | | | | | | | | | | | | | | | | | Update {get,put}_user macros for m32r kernel. - Modify get_user to use __get_user_asm macro, instead of __get_user_x macro. - Remove arch/m32r/lib/{get,put}user.S. - Some cosmetic updates. I would like to thank NIIBE Yutaka for his reporting about the m32r kernel's security problem in {get,put}_user macros. There were no address checking for user space access in {get,put}_user macros. ;-) Signed-off-by: Hirokazu Takata <takata@linux-m32r.org> Cc: NIIBE Yutaka <gniibe@fsij.org> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | SMP kernel This patch fixes a boot problem of the m32r SMP kernel 2.6.16-rc1-mm3 or later. In this patch, cpu_possible_map is statically initialized, and cpu_present_map is also copied from cpu_possible_map in smp_prepare_cpus(), because the m32r architecture has not supported CPU hotplug yet.

* [PATCH] alpha: SMP boot fixesBrian Uhrain says2006-04-112-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've encountered two problems with 2.6.16 and newer kernels on my API CS20 (dual 833MHz Alpha 21264b processors). The first is the kernel OOPSing because of a NULL pointer dereference while trying to populate SysFS with the CPU information. The other is that only one processor was being brought up. I've included a small Alpha-specific patch that fixes both problems. The first problem was caused by the CPUs never being properly registered using register_cpu(), the way it's done on other architectures. The second problem has to do with the removal of hwrpb_cpu_present_mask in arch/alpha/kernel/smp.c. In setup_smp() in the 2.6.15 kernel sources, hwrpb_cpu_present_mask has a bit set for each processor that is probed, and afterwards cpu_present_mask is set to the cpumask for the boot CPU. In the same function of the same file in the 2.6.16 sources, instead of hwrpb_cpu_present_mask being set, cpu_possible_map is updated for each probed CPU. cpu_present_mask is still set to the cpumask of the boot CPU afterwards. The problem lies in include/asm-alpha/smp.h, where cpu_possible_map is #define'd to be cpu_present_mask. Cleanups from: Ivan Kokshaysky <ink@jurassic.park.msu.ru> - cpu_present_mask and cpu_possible_map are essentially the same thing on alpha, as it doesn't support CPU hotplug; - allocate "struct cpu" only for present CPUs, like sparc64 does. Static array of "struct cpu" is just a waste of memory.

* [PATCH] swsusp: don't require bigsmpAshok Raj2006-04-111-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switching to automatic bigsmp causes a misleading error message, that more then 8 cpus are detected, and user needs to select either X86_GENERICARCH or X86_BIGSMP to handle. Reason is we switched to bigsmp to avoid IP race when new cpu is comming up. [bigsmp is nothing but using physical flat mode that can work for 1 .. 255 cpus] [default is X86_PC, that uses logical flat mode up to 8 CPUs max] Current x86_64 code uses bigsmp as default when hotplug is enabled. It would be preferable to make bigsmp as default, and work the dependencies of other related code like SMP_SUSPEND, and some related to memory hotplug code for i386. Current logical flat mode doesnt use shortcuts that cause the race by using the send_IPI_mask() instead of shortcuts when HOTPLUG_CPU is enabled. In the meantime this patch is the path of lease resistance. We will switch to bigsmp default sometime soon, when we get to work it again.

* [PATCH] frv: define MMU mode specific syscalls as 'cond_syscall' and clean ↵Hyok S. Choi2006-04-112-16/+22
| | | | | | | | | | | | | | | | | | | up unneeded macros For some architectures, a few syscalls are not linked in noMMU mode. In that case, the MMU depending syscalls are needed to be defined as 'cond_syscall'. For example, ARM architecture selectively links sys_mlock by the mode configuration. In case of FRV, it has been managed by #ifdef CONFIG_MMU macro in arch/frv/kernel/entry.S. However these conditional macros are just duplicates if they were defined as cond_syscall. Compilation test is done with FRV toolchains for both of MMU and noMMU mode. Signed-off-by: Hyok S.

* [PATCH] overcommit: add calculate_totalreserve_pages()Hideo AOKI2006-04-112-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These patches are an enhancement of OVERCOMMIT_GUESS algorithm in __vm_enough_memory(). - why the kernel needed patching When the kernel can't allocate anonymous pages in practice, currnet OVERCOMMIT_GUESS could return success. This implementation might be the cause of oom kill in memory pressure situation. If the Linux runs with page reservation features like /proc/sys/vm/lowmem_reserve_ratio and without swap region, I think the oom kill occurs easily. - the overall design approach in the patch When the OVERCOMMET_GUESS algorithm calculates number of free pages, the reserved free pages are regarded as non-free pages. This change helps to avoid the pitfall that the number of free pages become less than the number which the kernel tries to keep free. - testing results I tested the patches using my test kernel module. If the patches aren't applied to the kernel, __vm_enough_memory() returns success in the situation but autual page allocation is failed. On the other hand, if the patches are applied to the kernel, memory allocation failure is avoided since __vm_enough_memory() returns failure in the situation. I checked that on i386 SMP 16GB memory machine. I haven't tested on nommu environment currently. This patch adds totalreserve_pages for __vm_enough_memory(). Calculate_totalreserve_pages() checks maximum lowmem_reserve pages and pages_high in each zone. Finally, the function stores the sum of each zone to totalreserve_pages. The totalreserve_pages is calculated when the VM is initilized. And the variable is updated when /proc/sys/vm/lowmem_reserve_raito or /proc/sys/vm/min_free_kbytes are changed.

| * [ARM] 3473/1: Use numbers 0-15 for the VFP double registersCatalin Marinas2006-04-103-17/+11Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Catalin Marinas This patch changes the double registers numbering to 0-15 from even 0-30, in preparation for future VFP extensions. It also fixes the VFP_REG_ZERO bug (value 16 actually represents the 8th double register with the original numbering). The original mcrr/mrrc on CP10 were generating FMRRS/FMSRR instead of FMRRD/FMDRR. The patch changes to CP11 for the correct instructions.

| * [ARM] 3470/1: Clear the HWCAP bits for the disabled kernel featuresCatalin Marinas2006-04-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Catalin Marinas Glibc interprets the HWCAP bits and decides on what features to use. However, even if the features are present in the hardware, they are not always supported by the kernel and hence the corresponding bits have to be cleared from the elf_hwcap variable.

| | | | | | | | | | | | | | | | | | | | | | | | Patch from Tony Lindgren Recent change to use both id and name when available was not necessarily returning the right clock as it also searched for clock name afterwards.

| * [ARM] 3459/1: ixp23xx: fix debug serial macros for big-endian operationLennert Buytenhek2006-04-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek The debug-8250 macros do byte accesses, which means that if we're in big-endian mode, we need to logically OR the UART address with 3, as the LSB byte lane (where UART data and status is transferred) has the highest byte address in the word when we are in big-endian mode. It's unclear why this problem didn't surface earlier. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | We had two implementations for flushing the cache, which meant StrongARM caches weren't being correctly flushed. Fix this by always using the v4wb_flush_kern_cache_all method, rather than duplicating it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
