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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 c716a25b9b70084e1144f77423f5aedd772ea478 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_rainier_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/rainier_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_rainier_defconfig_powerpc 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:185:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /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:341:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x47d7ac) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.19.0-rc3-gc716a25b9b70 Created: Fri Sep 21 01:43:55 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2260478 Bytes = 2207.50 KiB = 2.16 MiB Load Address: 00500000 Entry Point: 0050110c Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_rainier_defconfig_powerpc # Build took: 0:00:34.527821
