[ Upstream commit c8e63985 ] 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:

[ Upstream commit f16db807 ] In some of the 'out_not_moved' error paths, lnum may be used uninitialized. Don't ignore the warning; let's fix it. This uninitialized variable doesn't have much visible effect in the end, since we just schedule the PEB for erasure, and its LEB number doesn't really matter (it just gets printed in debug messages).

[ Upstream commit f82263c6 ] 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).

[ Upstream commit c5e69192 ] When a event PADDING is hit (a deleted event that is still in the ring buffer), translate_data() sets the length of the padding and also updates the data pointer which is passed back to the caller. This is unneeded because the caller also updates the data pointer with the passed back length. translate_data() should not update the pointer, only set the length. Signed-off-by:

[ Upstream commit 8318e667 ] Invoking mount propagation from __detach_mounts is inefficient and wrong. It is inefficient because __detach_mounts already walks the list of mounts that where something needs to be done, and mount propagation walks some subset of those mounts again. It is actively wrong because if the dentry that is passed to __detach_mounts is not part of the path to a mount that mount should not be affected. change_mnt_propagation(p,MS_PRIVATE) modifies the mount propagation tree of a master mount so it's slaves are connected to another master if possible. Which means even removing a mount from the middle of a mount tree with __detach_mounts will not deprive any mount propagated mount events. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit e12fb972 ] 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:

[ Upstream commit b72c1869 ] 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).

[ Upstream commit a87938b2 ] 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:

[ Upstream commit bd884149 ] On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each time set_rate is done. In order to fix this, we will verify the firmware version, and if it matches the one in those laptops, the set_rate function is overloaded with a function elantech_set_rate_restore_reg_07 that performs the set_rate with the original function, followed by a restore of reg_07 (the register that sets the absolute mode on elantech v4 hardware). Also the ASUS TP500LN and X750JN firmware version, capabilities, and button constellation is added to elantech.c Cc: stable@vger.kernel.org Reported-and-tested-by:

If there's pcbeep functionality, it certainly isn't controlled by setting an amp on 0x0b, so disable beep functionality (at least for now).

[ Upstream commit 62f0342d ] Every USB Host controller should use this new macro to define for how long resume signalling should be driven on the bus. Currently, almost every single USB controller is using a 20ms timeout for resume signalling. That's problematic for two reasons: a) sometimes that 20ms timer expires a little before 20ms, which makes us fail certification b) some (many) devices actually need more than 20ms resume signalling. Sure, in case of (b) we can state that the device is against the USB spec, but the fact is that we have no control over which device the certification lab will use. We also have no control over which host they will use. Most likely they'll be using a Windows PC which, again, we have no control over how that USB stack is written and how long resume signalling they are using. At the end of the day, we must make sure Linux passes electrical compliance when working as Host or as Device and currently we don't pass compliance as host because we're driving resume signallig for exactly 20ms and that confuses certification test setup resulting in Certification failure.
