  • 1a0a397e4   dcache: d_obtain_alias callers don't all want DISCONNECTED ... Browse Code »

    There are a few d_obtain_alias callers that are using it to get the
    root of a filesystem which may already have an alias somewhere else.

    This is not the same as the filehandle-lookup case, and none of them
    actually need DCACHE_DISCONNECTED set.

    It isn't really a serious problem, but it would really be clearer if we
    reserved DCACHE_DISCONNECTED for those cases where it's actually needed.

    In the btrfs case this was causing a spurious printk from
    nfsd/nfsfh.c:fh_verify when it found an unexpected DCACHE_DISCONNECTED
    dentry. Josef worked around this by unsetting DCACHE_DISCONNECTED
    manually in 3a0dfa6a12e "Btrfs: unset DCACHE_DISCONNECTED when mounting
    default subvol", and this replaces that workaround.

  • bae36241b   NFS: Create a single nfs_get_root() ... Browse Code »

    This patch splits out the NFS v4 specific functionality of
    nfs4_get_root() into its own rpc_op called by the generic client, and
    leaves nfs4_proc_get_rootfh() as its own stand alone function. This
    also allows me to change nfs4_remote_mount(), nfs4_xdev_mount() and
    nfs4_remote_referral_mount() to use the generic client's nfs_get_root()
    function. Later patches in this series will collapse these functions
    into one common function, so using the same get_root() function
    everywhere simplifies future changes.

  • 3028eb2b3   NFS: Rename nfs4_proc_get_root() ... Browse Code »

    This function is really getting the root filehandle and not the root
    dentry of the filesystem. I also removed the rpc_ops lookup from
    nfs4_get_rootfh() under the assumption that if we reach this function
    then we already know we are using NFS v4.

  • 4667058b7   nfs4: Fix NULL dereference at d_alloc_and_lookup() ... Browse Code »

    d_alloc_and_lookup() calls i_op->lookup method due to
    rootfh changes his fsid.

    During mount i_op of NFS root inode is set to
    nfs_mountpoint_inode_operations, if rpc_ops->getroot()
    and rpc_ops->getattr() return different fsid.

    After that nfs_follow_remote_path() raised oops:

    BUG: unable to handle kernel NULL pointer dereference at (null)
    IP: [< (null)>] (null)

    stack trace:

    d_alloc_and_lookup+0x4c/0x74
    do_lookup+0x1e3/0x280
    link_path_walk+0x12e/0xab0
    nfs4_remote_get_sb+0x56/0x2c0 [nfs]

    So just refresh fsid, as RFC3530 doesn't specify behavior
    in case of rootfh changes fsid.

  • b1942c5f8   nfs: store devname at disconnected NFS roots ... Browse Code »

    part 2: make sure that disconnected roots have corresponding mnt_devname
    values stashed into them.

    Have nfs*_get_root() stuff a copy of devname into ->d_fsdata of the
    found root, provided that it is disconnected.

    Have ->d_release() free it when dentry goes away.

    Have the places where NFS uses ->d_fsdata for sillyrename (and that
    can *never* happen to a disconnected root - dentry will be attached
    to its parent) free old devname copies if they find those.

  • 873feea09   fs: dcache per-inode inode alias locking ... Browse Code »

    dcache_inode_lock can be replaced with per-inode locking. Use existing
    inode->i_lock for this. This is slightly non-trivial because we sometimes
    need to find the inode from the dentry, which requires d_inode to be
    stabilised (either with refcount or d_lock).

  • fb045adb9   fs: dcache reduce branches in lookup path ... Browse Code »

    Reduce some branches and memory accesses in dcache lookup by adding dentry
    flags to indicate common d_ops are set, rather than having to check them.
    This saves a pointer memory access (dentry->d_op) in common path lookup
    situations, and saves another pointer load and branch in cases where we
    have d_op but not the particular operation.

    Patched with:

    git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i

  • b09b9417d   NFS: Fix the ustat() regression ... Browse Code »

    Since 2.6.18, the superblock sb->s_root has been a dummy dentry with a
    dummy inode. This breaks ustat(), which actually uses sb->s_root in a
    vfstat() call.

    Fix this by making the s_root a dummy alias to the directory inode that was
    used when creating the superblock.

    It doesn't look as if the NFS file name limit is being initialised correctly
    in the struct nfs_server. Make sure that we limit whatever is being set in
    nfs_probe_fsinfo() and nfs_init_server().

    Also ensure that readdirplus and nfs4_path_walk respect our file name
    limits.
