In # hindsight, we should have spotted this in review when the PAN code was # merged back in v4.3, but hindsight is 20/20 and I'm trying not to beat # myself up too much about it despite being fairly miserable. # # Anyway, the fix is "obvious" but the actual failure is more more # subtle, and is described in the commit message. I've included a fairly # mechanical follow-up patch here as well, which moves this checking out # into the C wrappers which is what we do for {get,put}_user() already # and allows us to remove these bloody assembly macros entirely. The # patches have passed kernelci [1] [2] [3] and CKI [4] tests over night, # as well as some targetted testing [5] for this particular issue. # # The first patch is tagged for stable and should be applied to 4.14, # 4.19 and 5.3. I have separate backports for 4.4 and 4.9, which I'll # send out once this has landed in your tree (although the original # patch applies cleanly, it won't build for those two trees). # # Thanks to Pavel Tatashin for reporting this and Mark Rutland for # helping to diagnose the issue and review/test the solution" # # * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: # arm64: uaccess: Remove uaccess_*_not_uao asm macros # arm64: uaccess: Ensure PAN is re-enabled after unhandled uaccess fault # < /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 81429eb8d9ca40b0c65bb739d29fa856c5d5e958 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- corenet32_smp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_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/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' 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:338:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1496:5: warning: 'page' 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 /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0xd15238) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xe00000) Image Name: Linux-5.4.0-rc8-g81429eb8d9ca Created: Fri Nov 22 08:27:55 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6192880 Bytes = 6047.73 KiB = 5.91 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.6 # Build took: 0:01:58.685548
