  • As Reported by Randy Dunlap

    When MISC_FILESYSTEMS is not enabled and NFS4.1 is:

    fs/built-in.o: In function `objio_alloc_io_state':
    objio_osd.c:(.text+0xcb525): undefined reference to `ore_get_rw_state'
    fs/built-in.o: In function `_write_done':
    objio_osd.c:(.text+0xcb58d): undefined reference to `ore_check_io'
    fs/built-in.o: In function `_read_done':
    ...

    When MISC_FILESYSTEMS, which is more of a GUI thing then anything else,
    is not selected. exofs/Kconfig is never examined during Kconfig,
    and it can not do it's magic stuff to automatically select everything
    needed.

    We must split exofs/Kconfig in two. The ore one is always included.
    And the exofs one is left in it's old place in the menu.

  • Commit 990d6c2d7aee921e3bce22b2d6a750fd552262be ("vfs: Add name to file
    handle conversion support") changed EXPORTFS to be a bool.
    This was needed for earlier revisions of the original patch, but the actual
    commit put the code needing it into its own file that only gets compiled
    when FHANDLE is selected which in turn selects EXPORTFS.
    So EXPORTFS can be safely compiled as a module when not selecting FHANDLE.

  • Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL,
    even if it had been Y in oldconfig; and Linus reports that PulseAudio
    goes subtly wrong unless it can use ACLs on /dev/shm.

    Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS),
    and move the TMPFS_POSIX_ACL entry before the TMPFS_XATTR entry,
    to avoid asking unnecessary questions then ignoring their answers.

  • Implement generic xattrs for tmpfs filesystems. The Feodra project, while
    trying to replace suid apps with file capabilities, realized that tmpfs,
    which is used on the build systems, does not support file capabilities and
    thus cannot be used to build packages which use file capabilities. Xattrs
    are also needed for overlayfs.

    The xattr interface is a bit odd. If a filesystem does not implement any
    {get,set,list}xattr functions the VFS will call into some random LSM hooks
    and the running LSM can then implement some method for handling xattrs.
    SELinux for example provides a method to support security.selinux but no
    other security.* xattrs.

    As it stands today when one enables CONFIG_TMPFS_POSIX_ACL tmpfs will have
    xattr handler routines specifically to handle acls. Because of this tmpfs
    would loose the VFS/LSM helpers to support the running LSM. To make up
    for that tmpfs had stub functions that did nothing but call into the LSM
    hooks which implement the helpers.

    This new patch does not use the LSM fallback functions and instead just
    implements a native get/set/list xattr feature for the full security.* and
    trusted.* namespace like a normal filesystem. This means that tmpfs can
    now support both security.selinux and security.capability, which was not
    previously possible.

    The basic implementation is that I attach a:

    struct shmem_xattr {
    struct list_head list; /* anchored by shmem_inode_info->xattr_list */
    char *name;
    size_t size;
    char value[0];
    };

    Into the struct shmem_inode_info for each xattr that is set. This
    implementation could easily support the user.* namespace as well, except
    some care needs to be taken to prevent large amounts of unswappable memory
    being allocated for unprivileged users.

  • The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
    is used to configure any non-standard kernel with a much larger scope than
    only small devices.

    This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
    references to the option throughout the kernel. A new CONFIG_EMBEDDED
    option is added that automatically selects CONFIG_EXPERT when enabled and
    can be used in the future to isolate options that should only be
    considered for embedded systems (RISC architectures, SLOB, etc).

    Calling the option "EXPERT" more accurately represents its intention: only
    expert users who understand the impact of the configuration changes they
    are making should enable it.

  • Some platforms have a small amount of non-volatile storage that
    can be used to store information useful to diagnose the cause of
    a system crash. This is the generic part of a file system interface
    that presents information from the crash as a series of files in
    /dev/pstore. Once the information has been seen, the underlying
    storage is freed by deleting the files.

  • With all the patches we have queued in the BKL removal tree, only a
    few dozen modules are left that actually rely on the BKL, and even
    there are lots of low-hanging fruit. We need to decide what to do
    about them, this patch illustrates one of the options:

    Every user of the BKL is marked as 'depends on BKL' in Kconfig,
    and the CONFIG_BKL becomes a user-visible option. If it gets
    disabled, no BKL using module can be built any more and the BKL
    code itself is compiled out.

    The one exception is file locking, which is practically always
    enabled and does a 'select BKL' instead. This effectively forces
    CONFIG_BKL to be enabled until we have solved the fs/lockd
    mess and can apply the patch that removes the BKL from fs/locks.c.

  • smbfs has been scheduled for removal in 2.6.27, so
    maybe we can now move it to drivers/staging on the
    way out.

    smbfs still uses the big kernel lock and nobody
    is going to fix that, so we should be getting
    rid of it soon.

    This removes the 32 bit compat mount and ioctl
    handling code, which is implemented in common fs
    code, and moves all smbfs related files into
    drivers/staging/smbfs.

  • Nobody appears to be interested in fixing autofs3 bugs
    any more and it uses the BKL, which is going away.

    Move this to staging for retirement. Unless someone
    complains until 2.6.38, we can remove it for good.

    The include/linux/auto_fs.h header file is still used
    by autofs4, so it remains in place.

  • The hugetlb dependencies presently depend on SUPERH && MMU while the
    hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This
    unfortunately allows SH-3 + MMU configurations to enable hugetlbfs
    without a corresponding HPAGE_SHIFT definition, resulting in the build
    blowing up.

    As SH-3 doesn't support variable page sizes, we tighten up the
    dependenies a bit to prevent hugetlbfs from being enabled. These days
    we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using
    that rather than adding to the list of corner cases in fs/Kconfig.

  • CONFIG_SHMEM off gives you (ramfs masquerading as) tmpfs, even when
    CONFIG_TMPFS is off: that's a little anomalous, and I'd intended to make
    more sense of it by removing CONFIG_TMPFS altogether, always enabling its
    code when CONFIG_SHMEM; but so many defconfigs have CONFIG_SHMEM on
    CONFIG_TMPFS off that we'd better leave that as is.

    But there is no point in asking for CONFIG_TMPFS if CONFIG_SHMEM is off:
    make TMPFS depend on SHMEM, which also prevents TMPFS_POSIX_ACL
    shmem_acl.o being pointlessly built into the kernel when SHMEM is off.

    And a selfish change, to prevent the world from being rebuilt when I
    switch between CONFIG_SHMEM on and off: the only CONFIG_SHMEM in the
    header files is mm.h shmem_lock() - give that a shmem.c stub instead.

    Actually, nilfs is NOT a filesystem came from other operating systems,
    but a filesystem created purely for Linux. Nor is it a flash
    filesystem but that for generic block devices.

    So, this moves nilfs outside the misc category as I responded in LKML
    "Re: Why does NILFS2 hide under Miscellaneous filesystems?"
    (Message-Id: ).

  • CUSE enables implementing character devices in userspace. With recent
    additions of ioctl and poll support, FUSE already has most of what's
    necessary to implement character devices. All CUSE has to do is
    bonding all those components - FUSE, chardev and the driver model -
    nicely.

    When client opens /dev/cuse, kernel starts conversation with
    CUSE_INIT. The client tells CUSE which device it wants to create. As
    the previous patch made fuse_file usable without associated
    fuse_inode, CUSE doesn't create super block or inodes. It attaches
    fuse_file to cdev file->private_data during open and set ff->fi to
    NULL. The rest of the operation is almost identical to FUSE direct IO
    case.

    Each CUSE device has a corresponding directory /sys/class/cuse/DEVNAME
    (which is symlink to /sys/devices/virtual/class/DEVNAME if
    SYSFS_DEPRECATED is turned off) which hosts "waiting" and "abort"
    among other things. Those two files have the same meaning as the FUSE
    control files.

    The only notable lacking feature compared to in-kernel implementation
    is mmap support.
