  • 670c0d101   vfs: allow O_PATH file descriptors for fstatfs() ... Browse Code »

    commit 9d05746e7b16d8565dddbe3200faa1e669d23bbf upstream.

    Olga reported that file descriptors opened with O_PATH do not work with
    fstatfs(), found during further development of ksh93's thread support.

    There is no reason to not allow O_PATH file descriptors here (fstatfs is
    very much a path operation), so use "fdget_raw()". See commit
    55815f70147d ("vfs: make O_PATH file descriptors usable for 'fstat()'")
    for a very similar issue reported for fstat() by the same team.

  • 5c8a0fbba   VFS: fix statfs() automounter semantics regression ... Browse Code »
    1

    No one in their right mind would expect statfs() to not work on a
    automounter managed mount point. Fix it.

    [ I'm not sure about the "no one in their right mind" part. It's not
    mounted, and you didn't ask for it to be mounted. But nobody will
    really care, and this probably makes it match previous semantics, so..
    - Linus ]

    This mirrors the fix made to the quota code in 815d405ceff0d69646.

  • c8b91accf   clean statfs-like syscalls up ... Browse Code »

    New helpers: user_statfs() and fd_statfs(), taking userland pathname and
    descriptor resp. and filling struct kstatfs. Syscalls of statfs family
    (native, compat and foreign - osf and hpux on alpha and parisc resp.)
    switched to those. Removes some boilerplate code, simplifies cleanup
    on errors...

  • 365b18189   add f_flags to struct statfs(64) ... Browse Code »

    Add a flags field to help glibc implementing statvfs(3) efficiently.

    We copy the flag values from glibc, and add a new ST_VALID flag to
    denote that f_flags is implemented.

  • ebabe9a90   pass a struct path to vfs_statfs ... Browse Code »

    We'll need the path to implement the flags field for statvfs support.
    We do have it available in all callers except:

    - ecryptfs_statfs. This one doesn't actually need vfs_statfs but just
    needs to do a caller to the lower filesystem statfs method.
    - sys_ustat. Add a non-exported statfs_by_dentry helper for it which
    doesn't won't be able to fill out the flags field later on.

    In addition rename the helpers for statfs vs fstatfs to do_*statfs instead
    of the misleading vfs prefix.
