  • 5cbded585   [PATCH] getting rid of all casts of k[cmz]alloc() calls ... Browse Code »

    Run this:

    #!/bin/sh
    for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
    echo "De-casting $f..."
    perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
    done

    And then go through and reinstate those cases where code is casting pointers
    to non-pointers.

    And then drop a few hunks which conflicted with outstanding work.

  • afefdbb28   [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers ... Browse Code »

    These patches make the kernel pass 64-bit inode numbers internally when
    communicating to userspace, even on a 32-bit system. They are required
    because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
    for example. The 64-bit inode numbers are then propagated to userspace
    automatically where the arch supports it.

    Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
    number returned by stat64() or getdents64() to differentiate files, and
    failing because the 64-bit inode number space was compressed to 32-bits, and
    so overlaps occur.

    This patch:

    Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
    inode number so that 64-bit inode numbers can be passed back to userspace.

    The stat functions then returns the full 64-bit inode number where
    available and where possible. If it is not possible to represent the inode
    number supplied by the filesystem in the field provided by userspace, then
    error EOVERFLOW will be issued.

    Similarly, the getdents/readdir functions now pass the full 64-bit inode
    number to userspace where possible, returning EOVERFLOW instead when a
    directory entry is encountered that can't be properly represented.

    Note that this means that some inodes will not be stat'able on a 32-bit
    system with old libraries where they were before - but it does mean that
    there will be no ambiguity over what a 32-bit inode number refers to.

    Note similarly that directory scans may be cut short with an error on a
    32-bit system with old libraries where the scan would work before for the
    same reasons.

    It is judged unlikely that this situation will occur because modern glibc
    uses 64-bit capable versions of stat and getdents class functions
    exclusively, and that older systems are unlikely to encounter
    unrepresentable inode numbers anyway.

  • e9ff3990f   [PATCH] namespaces: utsname: switch to using uts namespaces ... Browse Code »

    Replace references to system_utsname to the per-process uts namespace
    where appropriate. This includes things like uname.

    Changes: Per Eric Biederman's comments, use the per-process uts namespace
    for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

  • 726c33422   [PATCH] VFS: Permit filesystem to perform statfs with a known root dentry ... Browse Code »

    Give the statfs superblock operation a dentry pointer rather than a superblock
    pointer.

    This complements the get_sb() patch. That reduced the significance of
    sb->s_root, allowing NFS to place a fake root there. However, NFS does
    require a dentry to use as a target for the statfs operation. This permits
    the root in the vfsmount to be used instead.

    linux/mount.h has been added where necessary to make allyesconfig build
    successfully.

    Interest has also been expressed for use with the FUSE and XFS filesystems.

  • 1fcbf053e   [PATCH] sys_hpux: fix strlen_user() race ... Browse Code »

    Userspace can alter the string after the kernel has run strlen_user().

    Also: the strlen_user() return value includes the \0, so fix that.

    Also: handle EFAULT from strlen_user().

    It's unlikely anyone is using this code. Very, very unlikely. If I
    remember correctly, CONFIG_HPUX turns this code on, but one would actually
    need CONFIG_BINFMT_SOM to load a binary that could cause a problem, and
    BINFMT_SOM has had an #error in it for quite some time.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
