However, if # this happens early before the RCU callback mechanism is available, # put_object() skips call_rcu() and frees the object directly. This is not # safe with the RCU list traversal in __kmemleak_do_cleanup(). # # Change the list traversal in __kmemleak_do_cleanup() to # list_for_each_entry_safe() and remove the rcu_read_{lock,unlock} since # the kmemleak is already disabled at this point. In addition, avoid an # unnecessary metadata object rb-tree look-up since it already has the # struct kmemleak_object pointer. # # Fixes: c5665868183f ("mm: kmemleak: use the memory pool for early allocations") # Reported-by: Alexey Kardashevskiy <aik@ozlabs.ru> # Reported-by: Marc Dionne <marc.c.dionne@gmail.com> # Reported-by: Ted Ts'o <tytso@mit.edu> # Cc: Andrew Morton <akpm@linux-foundation.org> # Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> # 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 2abd839aa7e615f2bbc50c8ba7deb9e40d186768 # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh-allnoconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- allnoconfig # make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh-allnoconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:388: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /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/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 ' Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sh-allnoconfig_sh4 # Build took: 0:00:11.496471
