But it's wrong, and adding # the proper user_access_end() is trivial enough (and doing it for the # other error cases where it isn't needed doesn't hurt). # # I noticed it while doing the same prep-work for changing # user_access_begin() that precipitated the access_ok() changes in commit # 96d4f267e40f ("Remove 'type' argument from access_ok() function"). # # Fixes: fddcd00a49e9 ("drm/i915: Force the slow path after a user-write error") # Cc: Chris Wilson <chris@chris-wilson.co.uk> # Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> # Cc: stable@kernel.org # v4.20 # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 0b2c8f8b6b0c7530e2866c95862546d0da2057b0 # < make -s -j 120 ARCH=sh O=/kisskb/build/linus_ap325rxa_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- ap325rxa_defconfig # make -s -j 120 ARCH=sh O=/kisskb/build/linus_ap325rxa_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1318:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1321:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1324:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1327:2: warning: #warning syscall statx not implemented [-Wcpp] <stdin>:1333:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1336:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:388: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:133:34: warning: 'levelspread[<Ubdc0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:100:6: note: 'levelspread[<Ubdc0>]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: 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/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' 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:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/ipv4/ip_output.c: In function '__ip_append_data': /kisskb/src/include/linux/skbuff.h:1338:6: warning: 'extra_uref' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/ipv4/ip_output.c:885:14: note: 'extra_uref' was declared here Image Name: Linux-4.20.0+ Created: Sat Jan 5 09:31:53 2019 Image Type: SuperH Linux Kernel Image (gzip compressed) Data Size: 3151871 Bytes = 3078.00 KiB = 3.01 MiB Load Address: 88001000 Entry Point: 88002000 Image arch/sh/boot/uImage is ready Completed OK # rm -rf /kisskb/build/linus_ap325rxa_defconfig_sh4 # Build took: 0:00:21.764644
