| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tm-resched-dscr test has started failing sometimes, depending on what compiler it's built with, eg: test: tm_resched_dscr Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed. !! child died by signal 6 When it fails we see that the compiler doesn't initialise rv to 1 before entering the inline asm block. Although that's counter intuitive, it is allowed because we tell the compiler that the inline asm will write to rv (using "=r"), meaning the original value is irrelevant. Marking it as a read/write parameter would presumably work, but it seems simpler to fix it by setting the initial value of rv in the inline asm.

One was simply a memory leak where not all was being freed that should have been in releasing a file pointer on set_graph_function. Then Thomas found that the ftrace trampolines were marked for read/write as well as execute. To shrink the possible attack surface, he added calls to set them to ro. Which also uncovered some other issues with freeing module allocated memory that had its permissions changed. Kprobes had a similar issue which is fixed and a selftest was added to trigger that issue again" * tag 'trace-v4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: x86/ftrace: Make sure that ftrace trampolines are not RWX x86/mm/ftrace: Do not bug in early boot on irqs_disabled in cpu_flush_range() selftests/ftrace: Add a testcase for many kprobe events kprobes/x86: Fix to set RWX bits correctly before releasing trampoline ftrace: Fix memory leak in ftrace_graph_release()

This tries to add many kprobe events (up to 256) on kernel functions. To avoid making ftrace-based kprobes (kprobes on fentry), it skips first N bytes (on x86 N=5, on ppc or arm N=4) of function entry. After that, it enables all those events, disable it, and remove it. Since the unoptimization buffer reclaiming will be delayed, after removing events, it will wait enough time.

* | | bpf: add various verifier test casesDaniel Borkmann2017-05-251-4/+235
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds various verifier test cases: 1) A test case for the pruning issue when tracking alignment is used. 2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer arithmetic turns such register into UNKNOWN_VALUE type. 3) Test cases for the special treatment of LD_ABS/LD_IND to make sure verifier doesn't break calling convention here. Latter is needed, since f.e. arm64 JIT uses r1 - r5 for storing temporary data, so they really must be marked as NOT_INIT.

| | * torture: Use correct path for Kconfig fragment for duplicatesPaul E. McKenney2017-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the rcutorture scripting will give an error message if running a duplicate scenario that happens also to have a non-existent build directory (b1, b2, ... in the rcutorture directory). Worse yet, if the build directory has already been created and used for a real build, the script will silently grab the wrong Kconfig fragment, which could cause confusion to the poor sap (me) analyzing old test results. At least the actual test runs correctly... This commit therefore accesses the Kconfig fragment from the results directory corresponding to the first of the duplicate scenarios, for which a build was actually carried out. This prevents both the messages and at least one form of later confusion. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

In check_types(), the last part of testcase compares with the hex value formatted by "%x" with a part of a string of long hex value (trimmed by tail -c and head -c). However, if that part of long hex value contains zero (e.g. "05" of "a3082059"), printf generated value (e.g. "5") is diffrent string, and the test case failed.

There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. - ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes.
