However, the test doesn't always segfault, causing the test to run a # single time. # # This patch fixes the test by putting it within a loop and jumping, via # setcontext, just prior to the loop in case it segfaults. This way we get the # desired behavior (run the test COUNT_MAX times) regardless if it segfaults or # not. This also reduces the use of setcontext for control flow logic, keeping it # only in the segfault handler. # # Also, since 'count' is changed within the signal handler, it is declared as # volatile to prevent any compiler optimization getting confused with # asynchronous changes. # # Signed-off-by: Gustavo Luiz Duarte <gustavold@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200203160906.24482-3-gustavold@linux.ibm.com # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 4399efc3f2f04ad8e6948461795de04ed1358402 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_iss476-smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/iss476-smp_defconfig WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] \|\| PPC_PMAC [=n] \|\| PPC_POWERNV [=n] \|\| FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=y] \|\| ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_iss476-smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c: In function 'blk_rq_map_sg': /kisskb/src/block/blk.h:79:50: warning: 'bvprv.bv_offset' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:486:42: note: 'bvprv.bv_offset' was declared here /kisskb/src/block/blk.h:82:12: warning: 'bvprv.bv_len' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:486:42: note: 'bvprv.bv_len' was declared here /kisskb/src/arch/powerpc/include/asm/io.h:802:22: warning: 'bvprv.bv_page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/block/blk-merge.c:486:42: note: 'bvprv.bv_page' was declared here /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/fs/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:5054:23: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x63d824) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x63d824) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_iss476-smp_defconfig_powerpc-gcc4.6 # Build took: 0:00:53.368114
