commit 9535c475 upstream. The hardware, according to the specs, is limited to 256 byte transfers, and current driver has no protections in case users attempt to do larger transfers. The code will just stomp over status register and mayhem ensues. Let's split larger transfers into digestable chunks. Doing this allows Atmel MXT driver on Pixel 1 function properly (it hasn't since commit 9d8dc3e5 "Input: atmel_mxt_ts - implement T44 message handling" which tries to consume multiple touchscreen/touchpad reports in a single transaction).

commit ca9b590c upstream. The current code decreases from the mss size (which is the gso_size from the kernel skb) the size of the packet headers. It shouldn't do that because the mss that comes from the stack (e.g IPoIB) includes only the tcp payload without the headers. The result is indication to the HW that each packet that the HW sends is smaller than what it could be, and too many packets will be sent for big messages. An easy way to demonstrate one more aspect of the problem is by configuring the ipoib mtu to be less than 2*hlen (2*56) and then run app sending big TCP messages. This will tell the HW to send packets with giant (negative value which under unsigned arithmetics becomes a huge positive one) length and the QP moves to SQE state.

commit 66578b0b upstream. In a call to ib_umem_get(), if address is 0x0 and size is already page aligned, check added in commit 8494057a ("IB/uverbs: Prevent integer overflow in ib_umem_get address arithmetic") will refuse to register a memory region that could otherwise be valid (provided vm.mmap_min_addr sysctl and mmap_low_allowed SELinux knobs allow userspace to map something at address 0x0). This patch allows back such registration: ib_umem_get() should probably don't care of the base address provided it can be pinned with get_user_pages(). There's two possible overflows, in (addr + size) and in PAGE_ALIGN(addr + size), this patch keep ensuring none of them happen while allowing to pin memory at address 0x0. Anyway, the case of size equal 0 is no more (partially) handled as 0-length memory region are disallowed by an earlier check.

commit 8abaae62 upstream. If ib_umem_get() is called with a size equal to 0 and an non-page aligned address, one page will be pinned and a 0-sized umem will be returned to the caller. This should not be allowed: it's not expected for a memory region to have a size equal to 0. This patch adds a check to explicitly refuse to register a 0-sized region.

commit 56cbd0cc upstream. mvsas is giving a General protection fault when it encounters an expander attached ATA device. Analysis of mvs_task_prep_ata() shows that the driver is assuming all ATA devices are locally attached and obtaining the phy mask by indexing the local phy table (in the HBA structure) with the phy id. Since expanders have many more phys than the HBA, this is causing the index into the HBA phy table to overflow and returning rubbish as the pointer. mvs_task_prep_ssp() instead does the phy mask using the port properties. Mirror this in mvs_task_prep_ata() to fix the panic. Reported-by:

commit 61819549 upstream. Level IRQ handlers and edge IRQ handler are managed by tow different sets of registers. But currently the driver uses the same mask for the both registers. It lead to issues with the following scenario: First, an IRQ is requested on a GPIO to be triggered on front. After, this an other IRQ is requested for a GPIO of the same bank but triggered on level. Then the first one will be also setup to be triggered on level. It leads to an interrupt storm. The different kind of handler are already associated with two different irq chip type. With this patch the driver uses a private mask for each one which solves this issue. It has been tested on an Armada XP based board and on an Armada 375 board. For the both boards, with this patch is applied, there is no such interrupt storm when running the previous scenario. This bug was already fixed but in a different way in the legacy version of this driver by Evgeniy Dushistov: 9ece8839 "ARM: orion: Fix for certain sequence of request_irq can cause irq storm". The fact the new version of the gpio drive could be affected had been discussed there: http://thread.gmane.org/gmane.linux.ports.arm.kernel/344670/focus=364012Reported-by:

commit 2b876010 upstream. ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451 It is reported that on a physically 64-bit addressed machine, 32-bit kernel can trigger crashes in accessing the memory regions that are beyond the 32-bit boundary. The region field's start address should still be 32-bit compliant, but after a calculation (adding some offsets), it may exceed the 32-bit boundary. This case is rare and buggy, but there are real BIOSes leaked with such issues (see References below). This patch fixes this gap by always defining IO addresses as 64-bit, and allows OSPMs to optimize it for a real 32-bit machine to reduce the size of the internal objects. Internal acpi_physical_address usages in the structures that can be fixed by this change include: 1. struct acpi_object_region: acpi_physical_address address; 2. struct acpi_address_range: acpi_physical_address start_address; acpi_physical_address end_address; 3. struct acpi_mem_space_context; acpi_physical_address address; 4. struct acpi_table_desc acpi_physical_address address; See known issues 1 for other usages. Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer from same problem, so this patch changes it accordingly. For iasl, it will enforce acpi_physical_address as 32-bit to generate 32-bit OSPM compatible tables on 32-bit platforms, we need to define ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h. Known issues: 1. Cleanup of mapped virtual address In struct acpi_mem_space_context, acpi_physical_address is used as a virtual address: acpi_physical_address mapped_physical_address; It is better to introduce acpi_virtual_address or use acpi_size instead. This patch doesn't make such a change. Because this should be done along with a change to acpi_os_map_memory()/acpi_os_unmap_memory(). There should be no functional problem to leave this unchanged except that only this structure is enlarged unexpectedly.

commit c8e63985 upstream. This patch fixes a bug for COMPARE_AND_WRITE handling with fabrics using SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC. It adds the missing allocation for cmd->t_bidi_data_sg within transport_generic_new_cmd() that is used by COMPARE_AND_WRITE for the initial READ payload, even if the fabric is already providing a pre-allocated buffer for cmd->t_data_sg. Also, fix zero-length COMPARE_AND_WRITE handling within the compare_and_write_callback() and target_complete_ok_work() to queue the response, skipping the initial READ. This fixes COMPARE_AND_WRITE emulation with loopback, vhost, and xen-backend fabric drivers using SG_TO_MEM_NOALLOC. Reported-by:

commit f82263c6 upstream. Since commit ee0778a3 ("tools/power: turbostat: make Makefile a bit more capable") turbostat's Makefile is using [...] BUILD_OUTPUT := $(PWD) [...] which obviously causes trouble when building "turbostat" with make -C /usr/src/linux/tools/power/x86/turbostat ARCH=x86 turbostat because GNU make does not update nor guarantee that $PWD is set. This patch changes the Makefile to use $CURDIR instead, which GNU make guarantees to set and update (i.e. when using "make -C ...") and also adds support for the O= option (see "make help" in your root of your kernel source tree for more details).

commit e12fb972 upstream. Previously commit 14ece102 added a support for for syncing parent directory of newly created inodes to make sure that the inode is not lost after a power failure in no-journal mode. However this does not work in majority of cases, namely: - if the directory has inline data - if the directory is already indexed - if the directory already has at least one block and: - the new entry fits into it - or we've successfully converted it to indexed So in those cases we might lose the inode entirely even after fsync in the no-journal mode. This also includes ext2 default mode obviously. I've noticed this while running xfstest generic/321 and even though the test should fail (we need to run fsck after a crash in no-journal mode) I could not find a newly created entries even when if it was fsynced before. Fix this by adjusting the ext4_add_entry() successful exit paths to set the inode EXT4_STATE_NEWENTRY so that fsync has the chance to fsync the parent directory as well. Signed-off-by:

commit 1915e2ad upstream. Building a kernel with CPU_BIG_ENDIAN fails if there are stale objects from a !CPU_BIG_ENDIAN build. Due to a missing FORCE prerequisite on an if_changed rule in the VDSO Makefile, we attempt to link a stale LE object into the new BE kernel.

commit b72c1869 upstream. ptrace_resume() is called when the tracee is still __TASK_TRACED. We set tracee->exit_code and then wake_up_state() changes tracee->state. If the tracer's sub-thread does wait() in between, task_stopped_code(ptrace => T) wrongly looks like another report from tracee. This confuses debugger, and since wait_task_stopped() clears ->exit_code the tracee can miss a signal. Test-case: #include <stdio.h> #include <unistd.h> #include <sys/wait.h> #include <sys/ptrace.h> #include <pthread.h> #include <assert.h> int pid; void *waiter(void *arg) { int stat; for (;;) { assert(pid == wait(&stat)); assert(WIFSTOPPED(stat)); if (WSTOPSIG(stat) == SIGHUP) continue; assert(WSTOPSIG(stat) == SIGCONT); printf("ERR! extra/wrong report:%x\n", stat); } } int main(void) { pthread_t thread; pid = fork(); if (!pid) { assert(ptrace(PTRACE_TRACEME, 0,0,0) == 0); for (;;) kill(getpid(), SIGHUP); } assert(pthread_create(&thread, NULL, waiter, NULL) == 0); for (;;) ptrace(PTRACE_CONT, pid, 0, SIGCONT); return 0; } Note for stable: the bug is very old, but without 9899d11f "ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL" the fix should use lock_task_sighand(child).

commit a87938b2 upstream. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary. Since the size of the "gap" on x86_64 is only guaranteed to be 128MB this means that binaries with large data segments > 128MB can end up mapping part of their data segment over their stack resulting in corruption of the stack (and the data segment once the binary starts to run). Any PIE binary with a data segment > 128MB is vulnerable to this although address randomization means that the actual gap between the stack and the end of the binary is normally greater than 128MB. The larger the data segment of the binary the higher the probability of failure. Fix this by calculating the total size of the binary in the same way as load_elf_interp(). Signed-off-by:
