| * selftests/powerpc: Fix TM resched DSCR test with some compilersMichael Ellerman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Borkmann2017-05-25
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. McKenney2017-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. To fix this, pass "%02x" instead of "%x" to printf.

By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap(). - Support for the new Power9 "XIVE" interrupt controller. - TLB flushing optimisations for the radix MMU on Power9. - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0". - The ability to configure the mmap randomisation limits at build and runtime. - Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE. - Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness. - Many fixes and other minor enhancements.
