That's an expected scenario and # the ocxl driver holds a reference on the mm_struct of the process # until the opencapi device is notified of the process exiting. # However, if mm_users is already at 0, i.e. the address space of the # process has already been destroyed, the driver shouldn't try resolving # the page fault, as it will fail, but it can also try accessing already # freed data. # # It is fixed by only calling the bottom half of the page fault handler # if mm_users is greater than 0 and get a reference on mm_users instead # of mm_count. Otherwise, we can safely return a translation fault to # the device, as its associated memory context is being removed. The # opencapi device will be properly cleaned up shortly after when closing # the file descriptors. # # Fixes: 5ef3166e8a32 ("ocxl: Driver code for 'generic' opencapi devices") # Cc: stable@vger.kernel.org # v4.16+ # Signed-off-by: Frederic Barrat <fbarrat@linux.ibm.com> # Reviewed-By: Alastair D'Silva <alastair@d-silva.org> # Acked-by: Andrew Donnellan <andrew.donnellan@au1.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 d497ebf5fb3a026c0817f8c96cde578787f24093 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_smp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc85xx_smp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_smp_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
