Hugh Dickins	1448dc70cd	mm: larger stack guard gap, between vmas ... commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream. Stack guard page is a useful feature to reduce a risk of stack smashing into a different mapping. We have been using a single page gap which is sufficient to prevent having stack adjacent to a different mapping. But this seems to be insufficient in the light of the stack usage in userspace. E.g. glibc uses as large as 64kB alloca() in many commonly used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX] which is 256kB or stack strings with MAX_ARG_STRLEN. This will become especially dangerous for suid binaries and the default no limit for the stack size limit because those applications can be tricked to consume a large portion of the stack and a single glibc call could jump over the guard page. These attacks are not theoretical, unfortunatelly. Make those attacks less probable by increasing the stack guard gap to 1MB (on systems with 4k pages; but make it depend on the page size because systems with larger base pages might cap stack allocations in the PAGE_SIZE units) which should cover larger alloca() and VLA stack allocations. It is obviously not a full fix because the problem is somehow inherent, but it should reduce attack space a lot. One could argue that the gap size should be configurable from userspace, but that can be done later when somebody finds that the new 1MB is wrong for some special case applications. For now, add a kernel command line option (stack_guard_gap) to specify the stack gap size (in page units). Implementation wise, first delete all the old code for stack guard page: because although we could get away with accounting one extra page in a stack vma, accounting a larger gap can break userspace - case in point, a program run with "ulimit -S -v 20000" failed when the 1MB gap was counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK and strict non-overcommit mode. Instead of keeping gap inside the stack vma, maintain the stack guard gap as a gap between vmas: using vm_start_gap() in place of vm_start (or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few places which need to respect the gap - mainly arch_get_unmapped_area(), and and the vma tree's subtree_gap support for that.

Userspace return code may skip restoring THREADPTR register if there are no registers that need to be zeroed. This leads to spurious failures in libc NPTL tests. Always restore THREADPTR on return to userspace. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2015-09-21 10:00:08 -07:00
Max Filippov	a2ed2ed6fe	xtensa: provide __NR_sync_file_range2 instead of __NR_sync_file_range ... commit 01e84c70fe40c8111f960987bcf7f931842e6d07 upstream. xtensa actually uses sync_file_range2 implementation, so it should define __NR_sync_file_range2 as other architectures that use that function. That fixes userspace interface (that apparently never worked) and avoids special-casing xtensa in libc implementations. See the thread ending at http://lists.busybox.net/pipermail/uclibc/2015-February/048833.html for more details.

Max Filippov	e86de8b5ea	xtensa: xtfpga: fix hardware lockup caused by LCD driver ... commit 4949009eb8d40a441dcddcd96e101e77d31cf1b2 upstream. LCD driver is always built for the XTFPGA platform, but its base address is not configurable, and is wrong for ML605/KC705. Its initialization locks up KC705 board hardware. Make the whole driver optional, and its base address and bus width configurable. Implement 4-bit bus access method.

Linus Torvalds	0c42d1fbb3	vm: add VM_FAULT_SIGSEGV handling support ... commit 33692f27597fcab536d7cbbcc8f52905133e4aa7 upstream. The core VM already knows about VM_FAULT_SIGBUS, but cannot return a "you should SIGSEGV" error, because the SIGSEGV case was generally handled by the caller - usually the architecture fault handler. That results in lots of duplication - all the architecture fault handlers end up doing very similar "look up vma, check permissions, do retries etc" - but it generally works. However, there are cases where the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV. In particular, when accessing the stack guard page, libsigsegv expects a SIGSEGV. And it usually got one, because the stack growth is handled by that duplicated architecture fault handler. However, when the generic VM layer started propagating the error return from the stack expansion in commit fee7e49d4514 ("mm: propagate error from stack expansion even for guard page"), that now exposed the existing VM_FAULT_SIGBUS result to user space. And user space really expected SIGSEGV, not SIGBUS. To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those duplicate architecture fault handlers about it. They all already have the code to handle SIGSEGV, so it's about just tying that new return value to the existing code, but it's all a bit annoying. This is the mindless minimal patch to do this. A more extensive patch would be to try to gather up the mostly shared fault handling logic into one generic helper routine, and long-term we really should do that cleanup. Just from this patch, you can generally see that most architectures just copied (directly or indirectly) the old x86 way of doing things, but in the meantime that original x86 model has been improved to hold the VM semaphore for shorter times etc and to handle VM_FAULT_RETRY and other "newer" things, so it would be a good idea to bring all those improvements to the generic case and teach other architectures about them too.

Johannes Weiner	e2ec2c2b96	arch: mm: pass userspace fault flag to generic fault handler ... commit 759496ba6407c6994d6a5ce3a5e74937d7816208 upstream. Unlike global OOM handling, memory cgroup code will invoke the OOM killer in any OOM situation because it has no way of telling faults occuring in kernel context - which could be handled more gracefully - from user-triggered faults. Pass a flag that identifies faults originating in user space from the architecture-specific fault handlers to generic code so that memcg OOM handling can be improved.

Max Filippov	af3a54ffc0	xtensa: fix TLBTEMP_BASE_2 region handling in fast_second_level_miss ... commit 7128039fe2dd3d59da9e4ffa036f3aaa3ba87b9f upstream. Current definition of TLBTEMP_BASE_2 is always 32K above the TLBTEMP_BASE_1, whereas fast_second_level_miss handler for the TLBTEMP region analyzes virtual address bit (PAGE_SHIFT + DCACHE_ALIAS_ORDER) to determine TLBTEMP region where the fault happened. The size of the TLBTEMP region is also checked incorrectly: not 64K, but twice data cache way size (whicht may as well be less than the instruction cache way size). Fix TLBTEMP_BASE_2 to be TLBTEMP_BASE_1 + data cache way size. Provide TLBTEMP_SIZE that is a greater of doubled data cache way size or the instruction cache way size, and use it to determine if the second level TLB miss occured in the TLBTEMP region. Practical occurence of page faults in the TLBTEMP area is extremely rare, this code can be tested by deletion of all w[di]tlb instructions in the tlbtemp_mapping region.

Uwe Kleine-König	2b4cc3cb58	Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP ... If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT.

Most in-kernel users want registers spilled on the kernel stack and don't require PS.EXCM to be set. That means that they don't need fixup routine and could reuse regular window overflow mechanism for that, which makes spill routine very simple.

The virtual address of boot parameters chain is passed to the kernel via a2 register. Adjust it in case it is remapped during MMUv3 -> MMUv2 mapping change, i.e. when it is in the first 128M. Also fix interpretation of initrd and FDT addresses passed in the boot parameters: these are physical addresses.

Johannes Weiner	0d49fb2dc7	arch: mm: pass userspace fault flag to generic fault handler ... Unlike global OOM handling, memory cgroup code will invoke the OOM killer in any OOM situation because it has no way of telling faults occuring in kernel context - which could be handled more gracefully - from user-triggered faults. Pass a flag that identifies faults originating in user space from the architecture-specific fault handlers to generic code so that memcg OOM handling can be improved.

Santosh Shilimkar	30909344af	of: Specify initrd location using 64-bit ... On some PAE architectures, the entire range of physical memory could reside outside the 32-bit limit. These systems need the ability to specify the initrd location using 64-bit numbers. This patch globally modifies the early_init_dt_setup_initrd_arch() function to use 64-bit numbers instead of the current unsigned long. There has been quite a bit of debate about whether to use u64 or phys_addr_t. It was concluded to stick to u64 to be consistent with rest of the device tree code. As summarized by Geert, "The address to load the initrd is decided by the bootloader/user and set at that point later in time. The dtb should not be tied to the kernel you are booting" More details on the discussion can be found here: https://lkml.org/lkml/2013/6/20/690 https://lkml.org/lkml/2012/9/13/544 Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Grant Likely <grant.likely@linaro.org> Git-commit: 374d5c9964c10373ba39bbe934f4262eb87d7114 Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git Signed-off-by: Ian Maund <imaund@codeaurora.org>	2014-02-07 13:49:42 -08:00
Jiang Liu	b78e83204c	mm: concentrate modification of totalram_pages into the mm core ... Concentrate code to modify totalram_pages into the mm core, so the arch memory initialized code doesn't need to take care of it. With these changes applied, only following functions from mm core modify global variable totalram_pages: free_bootmem_late(), free_all_bootmem(), free_all_bootmem_node(), adjust_managed_page_count(). With this patch applied, it will be much more easier for us to keep totalram_pages and zone->managed_pages in consistence.

Since commit f9a3879a (Fix sigaltstack corruption among cloned threads), current->sas_ss_size is set to 0 for cloned processes sharing VM with their parent. Don't use the (nonexistent) alternate signal stack in this case. This has been broken since commit 29c4dfd9 ([XTENSA] Remove non-rt signal handling).

Linus Torvalds	5647ac0ad4	Removal of GENERIC_GPIO for v3.10 ... GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage. This branch does the work to completely eliminate GENERIC_GPIO. However, it is not trivial to just create a branch to remove it. Over the course of the v3.9 cycle more code referencing GENERIC_GPIO has been added to linux-next that conflicts with this branch. The following must be done to resolve the conflicts when merging this branch into mainline: * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be replaced with CONFIG_GPIOLIB * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese documentation. * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB * definitions of the option in architecture Kconfig code should be deleted. Stephen has 3 merge fixup patches[1] that do the above. They are currently applicable on mainline as of May 2nd.

Max Filippov	895666a992	xtensa: disable IRQs while IRQ handler is running ... IRQ handlers are expected to run with IRQs disabled. See e.g. http://lwn.net/Articles/380931/ for a longer story. This was overlooked in the commit 2d1c645 xtensa: dispatch medium-priority interrupts Revert to old behavior and simplify interrupt entry and exit code. Interrupt handler still honours IRQ priority. do_notify_resume/schedule must be called with interrupts enabled, enable interrupts if we return from user exception.

Max Filippov	3ae908c99e	xtensa: provide custom CALLER_ADDR* implementations ... Definition of CALLER_ADDR* through __builtin_return_address makes compiler insert calls to __xtensa_libgcc_window_spill, which in turn makes fast_syscall_spill_registers syscall that clobbers registers when called from the kernel mode, leading to invalid opcode exceptions on return to userspace. Provide definition for CALLER_ADDR0 as MAKE_PC_FROM_RA(a0, a1) and in case CONFIG_FRAME_POINTER is enabled extract CALLER_ADDR{1-3} from stack.
