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-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 2abd839aa7e615f2bbc50c8ba7deb9e40d186768 # < make -s -j 80 ARCH=sparc O=/kisskb/build/linus_sparc-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 80 ARCH=sparc O=/kisskb/build/linus_sparc-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] kernel: arch/sparc/boot/image is ready kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sparc-defconfig_sparc64 # Build took: 0:00:41.739842
