  • 9c2462472   KSYM_SYMBOL_LEN fixes ... Browse Code »

    Miles Lane tailing /sys files hit a BUG which Pekka Enberg has tracked
    to my 966c8c12dc9e77f931e2281ba25d2f0244b06949 sprint_symbol(): use
    less stack exposing a bug in slub's list_locations() -
    kallsyms_lookup() writes a 0 to namebuf[KSYM_NAME_LEN-1], but that was
    beyond the end of page provided.

    The 100 slop which list_locations() allows at end of page looks roughly
    enough for all the other stuff it might print after the symbol before
    it checks again: break out KSYM_SYMBOL_LEN earlier than before.

    Latencytop and ftrace and are using KSYM_NAME_LEN buffers where they
    need KSYM_SYMBOL_LEN buffers, and vmallocinfo a 2*KSYM_NAME_LEN buffer
    where it wants a KSYM_SYMBOL_LEN buffer: fix those before anyone copies
    them.

  • 49c50342c   pagemap: fix 32-bit pagemap regression ... Browse Code »

    The large pages fix from bcf8039ed45 broke 32-bit pagemap by pulling the
    pagemap entry code out into a function with the wrong return type.
    Pagemap entries are 64 bits on all systems and unsigned long is only 32
    bits on 32-bit systems.

  • 6c87df37d   proc: revert /proc/uptime to ->read_proc hook ... Browse Code »

    Turned out some VMware userspace does pread(2) on /proc/uptime, but
    seqfiles currently don't allow pread() resulting in -ESPIPE.

    Seqfiles in theory can do pread(), but this can be a long story,
    so revert to ->read_proc until then.
