  • 6c5450ef6   efivarfs: Make efivarfs_file_ioctl() static ... Browse Code »

    There are no callers except through the file_operations struct below
    this, so it should be static like everything else here.

  • ed8b0de5a   efi: Make efivarfs entries immutable by default ... Browse Code »

    "rm -rf" is bricking some peoples' laptops because of variables being
    used to store non-reinitializable firmware driver data that's required
    to POST the hardware.

    These are 100% bugs, and they need to be fixed, but in the mean time it
    shouldn't be easy to *accidentally* brick machines.

    We have to have delete working, and picking which variables do and don't
    work for deletion is quite intractable, so instead make everything
    immutable by default (except for a whitelist), and make tools that
    aren't quite so broad-spectrum unset the immutable flag.

  • 5955102c9   wrappers for ->i_mutex access ... Browse Code »

    parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested},
    inode_foo(inode) being mutex_foo(&inode->i_mutex).

    Please, use those for access to ->i_mutex; over the coming cycle
    ->i_mutex will become rwsem, with ->lookup() done with it held
    only shared.

  • 3fab70c16   efivarfs: Never return ENOENT from firmware again ... Browse Code »

    Previously in 1fa7e69 efi_status_to_err() translated firmware status
    EFI_NOT_FOUND to -EIO instead of -ENOENT for efivarfs operations to
    avoid confusion. After refactoring in e14ab23, it is also used in other
    places where the translation may be unnecessary.

    So move the translation to efivarfs specific code. Also return EOF
    for reading zero-length files, which is what users would expect.

    Pull VFS updates from Al Viro,

    Misc cleanups all over the place, mainly wrt /proc interfaces (switch
    create_proc_entry to proc_create(), get rid of the deprecated
    create_proc_read_entry() in favor of using proc_create_data() and
    seq_file etc).

    7kloc removed.

  • d68772b7c   efivarfs: Move to fs/efivarfs ... Browse Code »

    Now that efivarfs uses the efivar API, move it out of efivars.c and
    into fs/efivarfs where it belongs. This move will eventually allow us
    to enable the efivarfs code without having to also enable
    CONFIG_EFI_VARS built, and vice versa.

    Furthermore, things like,

    mount -t efivarfs none /sys/firmware/efi/efivars

    will now work if efivarfs is built as a module without requiring the
    use of MODULE_ALIAS(), which would have been necessary when the
    efivarfs code was part of efivars.c.
