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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 2abd839aa7e615f2bbc50c8ba7deb9e40d186768 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:38: LSE atomics not supported by binutils /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:14, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_dma_rx_submit': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1351:16: note: 'flags' was declared here unsigned long flags; ^ Completed OK # rm -rf /kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 # Build took: 0:02:43.497307
