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/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 2abd839aa7e615f2bbc50c8ba7deb9e40d186768 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc40x_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/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /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 INFO: Uncompressed kernel (size 0x53d744) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53d744) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x52d0d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53d744) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x53d744) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.4.0-rc3-g2abd839aa7e6 Created: Tue Oct 15 03:56:26 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2627130 Bytes = 2565.56 KiB = 2.51 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.4.0-rc3-g2abd839aa7e6 Created: Tue Oct 15 03:56:26 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2661642 Bytes = 2599.26 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006019cc Image Name: Linux-5.4.0-rc3-g2abd839aa7e6 Created: Tue Oct 15 03:56:26 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2660998 Bytes = 2598.63 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 00601758 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:52.415885
