  • 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.

    Now that the headers are fixed and carry their own wait, all fs/nfsd/
    source files can include a minimal set of headers. and still compile just
    fine.

    This patch should improve the compilation speed of the nfsd module.

    * 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.

  • 3ab4d8b12   knfsd: nfsd: set rq_client to ip-address-determined-domain ... Browse Code »

    We want it to be possible for users to restrict exports both by IP address and
    by pseudoflavor. The pseudoflavor information has previously been passed
    using special auth_domains stored in the rq_client field. After the preceding
    patch that stored the pseudoflavor in rq_pflavor, that's now superfluous; so
    now we use rq_client for the ip information, as auth_null and auth_unix do.

    However, we keep around the special auth_domain in the rq_gssclient field for
    backwards compatibility purposes, so we can still do upcalls using the old
    "gss/pseudoflavor" auth_domain if upcalls using the unix domain to give us an
    appropriate export. This allows us to continue supporting old mountd.

    In fact, for this first patch, we always use the "gss/pseudoflavor"
    auth_domain (and only it) if it is available; thus rq_client is ignored in the
    auth_gss case, and this patch on its own makes no change in behavior; that
    will be left to later patches.

    Note on idmap: I'm almost tempted to just replace the auth_domain in the idmap
    upcall by a dummy value--no version of idmapd has ever used it, and it's
    unlikely anyone really wants to perform idmapping differently depending on the
    where the client is (they may want to perform *credential* mapping
    differently, but that's a different matter--the idmapper just handles id's
    used in getattr and setattr). But I'm updating the idmapd code anyway, just
    out of general backwards-compatibility paranoia.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • f35279d3f   [PATCH] sunrpc: cache_register can use wrong module reference ... Browse Code »

    When registering an RPC cache, cache_register() always sets the owner as the
    sunrpc module. However, there are RPC caches owned by other modules. With
    the incorrect owner setting, the real owning module can be removed potentially
    with an open reference to the cache from userspace.

    For example, if one were to stop the nfs server and unmount the nfsd
    filesystem, the nfsd module could be removed eventhough rpc.idmapd had
    references to the idtoname and nametoid caches (i.e.
    /proc/net/rpc/nfs4./channel is still open). This resulted in a
    system panic on one of our machines when attempting to restart the nfs
    services after reloading the nfsd module.

    The following patch adds a 'struct module *owner' field in struct
    cache_detail. The owner is further assigned to the struct proc_dir_entry
    in cache_register() so that the module cannot be unloaded while user-space
    daemons have an open reference on the associated file under /proc.

    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!
