Don't waste time checking it. If # someone tries to access it, it will SIGFAULT the same way as for # address 1, so no need to make it special. # # The special case is when not doing a write, in that case we want # to drop the entire function. This is now handled by 'dir' param # and not by the nulity of 'to' anymore. # # Also make beginning of prevent_user_access() similar # to beginning of allow_user_access(), and tell the compiler # that writing in kernel space or with a 0 length is unlikely # # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/d79cb9f680f4e971e05262303103a4b94baa91ce.1579715466.git.christophe.leroy@c-s.fr # < /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 932bba9c9c94d08fe4c8075bf55cafa0a5c16e2b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_52xx_tqm5200_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 52xx/tqm5200_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_52xx_tqm5200_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/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/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/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 0x5f3b58) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.5.0-rc5-g932bba9c9c94 Created: Fri Jan 24 03:49:59 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3041065 Bytes = 2969.79 KiB = 2.90 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_52xx_tqm5200_defconfig_powerpc-gcc4.6 # Build took: 0:01:03.411053
