      Fix for buffer overflow in ldm_frag_add not sufficient · cae13fe4
      Timo Warns authored
      As Ben Hutchings discovered [1], the patch for CVE-2011-1017 (buffer
      overflow in ldm_frag_add) is not sufficient.  The original patch in
      commit c340b1d6 ("fs/partitions/ldm.c: fix oops caused by corrupted
      partition table") does not consider that, for subsequent fragments,
      previously allocated memory is used.

      powerpc: Fix 32-bit SMP build · 6de06f31
      Josh Boyer authored
      Commit 69e3cea8 ("powerpc/smp: Make start_secondary_resume
      available to all CPU variants") introduced start_secondary_resume to
      misc_32.S, however it uses a 64-bit instruction which is not valid on
      32-bit platforms.  Use 'stw' instead.

      ipc: Add missing sys_ni entries for ipc/compat.c functions · be84bfcc
      Kevin Cernekee authored
      When building with:
      
        CONFIG_64BIT=y
        CONFIG_MIPS32_COMPAT=y
        CONFIG_COMPAT=y
        CONFIG_MIPS32_O32=y
        CONFIG_MIPS32_N32=y
        CONFIG_SYSVIPC is not set
        (and implicitly: CONFIG_SYSVIPC_COMPAT is not set)
      
      the final link fails with unresolved symbols for:
      
        compat_sys_semctl, compat_sys_msgsnd, compat_sys_msgrcv,
        compat_sys_shmctl, compat_sys_msgctl, compat_sys_semtimedop
      
      The fix is to add cond_syscall declarations for all syscalls in
      ipc/compat.c

      sanitize <linux/prefetch.h> usage · 268bb0ce
      Linus Torvalds authored
      Commit e66eed65 ("list: remove prefetching from regular list
      iterators") removed the include of prefetch.h from list.h, which
      uncovered several cases that had apparently relied on that rather
      obscure header file dependency.
      
      So this fixes things up a bit, using
      
         grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
         grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')
      
      to guide us in finding files that either need <linux/prefetch.h>
      inclusion, or have it despite not needing it.
      
      There are more of them around (mostly network drivers), but this gets
      many core ones.
