The problem is that of_property_read_u32_array() already # returns the value converted to the CPU byte order. # # The value of pkeys_total ends up more or less sane because there's a min() # call in pkey_initialize() which reduces pkeys_total to 32. So in practice # the kernel ignores the fact that the hypervisor reserved one key for # itself (the device tree advertises 31 keys in my test VM). # # This is wrong, but the effect in practice is that when a process tries to # allocate the 32nd key, it gets an -EINVAL error instead of -ENOSPC which # would indicate that there aren't any keys available # # Fixes: cf43d3b26452 ("powerpc: Enable pkey subsystem") # Cc: stable@vger.kernel.org # v4.16+ # Signed-off-by: Thiago Jung Bauermann <bauerman@linux.ibm.com> # 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 # < git log --format=%s --max-count=1 c716a25b9b70084e1144f77423f5aedd772ea478 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig configs/2006/11/29/pmac32_defconfigkexec # yes \n \| make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-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 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:223:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:886:36: note: 'speaker_vol' was declared here struct snd_kcontrol master_vol, speaker_vol; ^ INFO: Uncompressed kernel (size 0x8b2720) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_pmac32_defconfig+kexec_powerpc-gcc5 # Build took: 0:00:33.157292
