  • 3460f29a2   lockd: Introduce new-style XDR functions for NLMv4 ... Browse Code »

    We'd like to prevent local buffer overflows caused by malicious or
    broken servers. New xdr_stream style decoders can do that.

    For efficiency, we also want to be able to pass xdr_streams from
    call_encode() to all XDR encoding functions, rather than building
    an xdr_stream in every XDR encoding function in the kernel.

    Same idea as the NLM v3 XDR overhaul.

    * remove asm/atomic.h inclusion from linux/utsname.h --
    not needed after kref conversion
    * remove linux/utsname.h inclusion from files which do not need it

    NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
    due to some personality stuff it _is_ needed -- cowardly leave ELF-related
    headers and files alone.

  • 576df4634   NLM: Decode "priv" argument of NLMPROC_SM_NOTIFY as an opaque ... Browse Code »

    The NLM XDR decoders for the NLMPROC_SM_NOTIFY procedure should treat
    their "priv" argument truly as an opaque, as defined by the protocol,
    and let the upper layers figure out what is in it.

    This will make it easier to modify the contents and interpretation of
    the "priv" argument, and keep knowledge about what's in "priv" local
    to fs/lockd/mon.c.

    For now, the NLM and NSM implementations should behave exactly as they
    did before.

    The formation of the address of the rebooted host in
    nlm_host_rebooted() may look a little strange, but it is the inverse
    of how nsm_init_private() forms the private cookie. Plus, it's
    going away soon anyway.

  • 9a38a8388   lockd: Remove unused fields in the nlm_reboot structure ... Browse Code »

    The nlm_reboot structure is used to store information provided by the
    NSM_NOTIFY procedure. This procedure is not specified by the NLM or NSM
    protocols, other than to say that the procedure can be used to transmit
    information private to a particular NLM/NSM implementation.

    For Linux, the callback arguments include the name of the monitored host,
    the new NSM state of the host, and a 16-byte private opaque.

    As a clean up, remove the unused fields and the server-side XDR logic that
    decodes them.

  • 2bea90d43   SUNRPC: RPC buffer size estimates are too large ... Browse Code »

    The RPC buffer size estimation logic in net/sunrpc/clnt.c always
    significantly overestimates the requirements for the buffer size.
    A little instrumentation demonstrated that in fact rpc_malloc was never
    allocating the buffer from the mempool, but almost always called kmalloc.

    To compute the size of the RPC buffer more precisely, split p_bufsiz into
    two fields; one for the argument size, and one for the result size.

    Then, compute the sum of the exact call and reply header sizes, and split
    the RPC buffer precisely between the two. That should keep almost all RPC
    buffers within the 2KiB buffer mempool limit.

    And, we can finally be rid of RPC_SLACK_SPACE!

  • 511d2e885   NLM: Shrink the maximum request size of NLM4 requests ... Browse Code »

    NLM version 4 requests estimate the call and reply header sizes rather
    conservatively, using the very maximum size allowed in the protocol even
    though Linux always uses only a small fraction of the allowable space.

    Reduce the size of caller and lock arguments to conserve RPC buffer space
    while XDR encoding NLM4 arguments. Add compile-time checks to ensure the
    hostname string won't overflow NLM protocol maximums.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
