This test also tries to cause a page fault at a signal # handler, exactly between MSR[TS] set and tm_recheckpoint(), forcing # thread->texasr to be rewritten with TEXASR[FS] = 0, which will cause a BUG # when tm_recheckpoint() is called. # # This test is not deterministic, since it is hard to guarantee that the page # access will cause a page fault. In order to force more page faults at # signal context, the signal handler and the ucontext are being mapped into a # MADV_DONTNEED memory chunks. # # Tests have shown that the bug could be exposed with few interactions in a # buggy kernel. This test is configured to loop 5000x, having a good chance # to hit the kernel issue in just one run. This self test takes less than # two seconds to run. # # This test uses set/getcontext because the kernel will recheckpoint # zeroed structures, causing the test to segfault, which is undesired because # the test needs to rerun, so, there is a signal handler for SIGSEGV which # will restart the test. # # v2: Uses the MADV_DONTNEED memory advice # v3: Fix memcpy and 32-bits compilation # v4: Does not define unused macros # # Signed-off-by: Breno Leitao <leitao@debian.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 ebda7e3c2ebb244682d068c7d9ad8ad25404295a # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_SPLPAR_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # Added to kconfig CONFIG_PPC_SPLPAR=n # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_SPLPAR_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_SPLPAR_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: modpost: Found 3 section mismatch(es).
