  • bf118a342   NFSv4: include bitmap in nfsv4 get acl data ... Browse Code »
    129

    The NFSv4 bitmap size is unbounded: a server can return an arbitrary
    sized bitmap in an FATTR4_WORD0_ACL request. Replace using the
    nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server
    with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data
    xdr length to the (cached) acl page data.

    This is a general solution to commit e5012d1f "NFSv4.1: update
    nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead
    when getting ACLs.

    Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr
    was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

  • 6650239a4   NFS: Don't use vm_map_ram() in readdir ... Browse Code »

    vm_map_ram() is not available on NOMMU platforms, and causes trouble
    on incoherrent architectures such as ARM when we access the page data
    through both the direct and the virtual mapping.

    The alternative is to use the direct mapping to access page data
    for the case when we are not crossing a page boundary, but to copy
    the data into a linear scratch buffer when we are accessing data
    that spans page boundaries.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • e5cff482c   SUNRPC: Use unsigned string lengths in xdr_decode_string_inplace ... Browse Code »

    XDR strings, opaques, and net objects should all use unsigned lengths.
    To wit, RFC 4506 says:

    4.2. Unsigned Integer

    An XDR unsigned integer is a 32-bit datum that encodes a non-negative
    integer in the range [0,4294967295].

    ...

    4.11. String

    The standard defines a string of n (numbered 0 through n-1) ASCII
    bytes to be the number n encoded as an unsigned integer (as described
    above), and followed by the n bytes of the string.

    After this patch, xdr_decode_string_inplace now matches the other XDR
    string and array helpers that take a string length argument. See:

    xdr_encode_opaque_fixed, xdr_encode_opaque, xdr_encode_array

  • 4dc3b16ba   [PATCH] DocBook: changes and extensions to the kernel documentation ... Browse Code »

    I have recompiled Linux kernel 2.6.11.5 documentation for me and our
    university students again. The documentation could be extended for more
    sources which are equipped by structured comments for recent 2.6 kernels. I
    have tried to proceed with that task. I have done that more times from 2.6.0
    time and it gets boring to do same changes again and again. Linux kernel
    compiles after changes for i386 and ARM targets. I have added references to
    some more files into kernel-api book, I have added some section names as well.
    So please, check that changes do not break something and that categories are
    not too much skewed.

    I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
    by kernel convention. Most of the other changes are modifications in the
    comments to make kernel-doc happy, accept some parameters description and do
    not bail out on errors. Changed to @pid in the description, moved some
    #ifdef before comments to correct function to comments bindings, etc.

    You can see result of the modified documentation build at
    http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

    Some more sources are ready to be included into kernel-doc generated
    documentation. Sources has been added into kernel-api for now. Some more
    section names added and probably some more chaos introduced as result of quick
    cleanup work.
