  • This is trivial to do:

    - add flags argument to foo_rename()
    - check if flags is zero
    - assign foo_rename() to .rename2 instead of .rename

    This doesn't mean it's impossible to support RENAME_NOREPLACE for these
    filesystems, but it is not trivial, like for local filesystems.
    RENAME_NOREPLACE must guarantee atomicity (i.e. it shouldn't be possible
    for a file to be created on one host while it is overwritten by rename on
    another host).

    Filesystems converted:

    9p, afs, ceph, coda, ecryptfs, kernfs, lustre, ncpfs, nfs, ocfs2, orangefs.

    After this, we can get rid of the duplicate interfaces for rename.

    to inode_change_ok() instead of an inode. Also rename inode_change_ok()

    It fixed a local root exploit but also introduced a dependency on
    the lower file system implementing an mmap operation just to open a file,
    which is a bit of a heavy hammer. The right fix is to have mmap depend
    on the existence of the mmap handler instead.

  • smack ->d_instantiate() uses ->setxattr(), so to be able to call it before
    we'd hashed the new dentry and attached it to inode, we need ->setxattr()
    instances getting the inode as an explicit argument rather than obtaining
    it from dentry.

    Similar change for ->getxattr() had been done in commit ce23e64. Unlike
    ->getxattr() (which is used by both selinux and smack instances of
    ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately
    it got missed back then.

  • Pull parallel filesystem directory handling update from Al Viro.

    This is the main parallel directory work by Al that makes the vfs layer
    able to do lookup and readdir in parallel within a single directory.
    That's a big change, since this used to be all protected by the
    directory inode mutex.

    The inode mutex is replaced by an rwsem, and serialization of lookups of
    a single name is done by a "in-progress" dentry marker.

    The series begins with xattr cleanups, and then ends with switching
    filesystems over to actually doing the readdir in parallel (switching to
    the "iterate_shared()" that only takes the read lock).

    A more detailed explanation of the process from Al Viro:
    "The xattr work starts with some acl fixes, then switches ->getxattr to
    passing inode and dentry separately. This is the point where the
    things start to get tricky - that got merged into the very beginning
    of the -rc3-based #work.lookups, to allow untangling the
    security_d_instantiate() mess. The xattr work itself proceeds to
    switch a lot of filesystems to generic_...xattr(); no complications
    there.

    After that initial xattr work, the series then does the following:

    - untangle security_d_instantiate()

    - convert a bunch of open-coded lookup_one_len_unlocked() to calls of
    that thing; one such place (in overlayfs) actually yields a trivial
    conflict with overlayfs fixes later in the cycle - overlayfs ended
    up switching to a variant of lookup_one_len_unlocked() sans the
    permission checks. I would've dropped that commit (it gets
    overridden on merge from #ovl-fixes in #for-next; proper resolution
    is to use the variant in mainline fs/overlayfs/super.c), but I
    didn't want to rebase the damn thing - it was fairly late in the
    cycle...

    - some filesystems had managed to depend on lookup/lookup exclusion
    for *fs-internal* data structures in a way that would break if we
    relaxed the VFS exclusion. Fixing hadn't been hard, fortunately.

    - core of that series - parallel lookup machinery, replacing
    ->i_mutex with rwsem, making lookup_slow() take it only shared. At
    that point lookups happen in parallel; lookups on the same name
    wait for the in-progress one to be done with that dentry.

    Surprisingly little code, at that - almost all of it is in
    fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
    making it use the new primitive and actually switching to locking
    shared.

    - parallel readdir stuff - first of all, we provide the exclusion on
    per-struct file basis, same as we do for read() vs lseek() for
    regular files. That takes care of most of the needed exclusion in
    readdir/readdir; however, these guys are trickier than lookups, so
    I went for switching them one-by-one. To do that, a new method
    '->iterate_shared()' is added and filesystems are switched to it
    as they are either confirmed to be OK with shared lock on directory
    or fixed to be OK with that. I hope to kill the original method
    come next cycle (almost all in-tree filesystems are switched
    already), but it's still not quite finished.

    - several filesystems get switched to parallel readdir. The
    interesting part here is dealing with dcache preseeding by readdir;
    that needs minor adjustment to be safe with directory locked only
    shared.

    Most of the filesystems doing that got switched to in those
    commits. Important exception: NFS. Turns out that NFS folks, with
    their, er, insistence on VFS getting the fuck out of the way of the
    Smart Filesystem Code That Knows How And What To Lock(tm) have
    grown the locking of their own. They had their own homegrown
    rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
    is the reader there). Of course, with VFS getting the fuck out of
    the way, as requested, the actual smarts of the smart filesystem
    code etc. had become exposed...

    - do_last/lookup_open/atomic_open cleanups. As the result, open()
    without O_CREAT locks the directory only shared. Including the
    ->atomic_open() case. Backmerge from #for-linus in the middle of
    that - atomic_open() fix got brought in.

    - then comes NFS switch to saner (VFS-based ;-) locking, killing the
    homegrown "lookup and readdir are writers" kinda-sorta rwsem. All
    exclusion for sillyunlink/lookup is done by the parallel lookups
    mechanism. Exclusion between sillyunlink and rmdir is a real rwsem
    now - rmdir being the writer.

    Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
    now.

    - the rest of the series consists of switching a lot of filesystems
    to parallel readdir; in a lot of cases ->llseek() gets simplified
    as well. One backmerge in there (again, #for-linus - rockridge
    fix)"

  • First of all, trying to open them r/w is idiocy; it's guaranteed to fail.
    Moreover, assigning ->f_pos and assuming that everything will work is
    blatantly broken - try that with e.g. tmpfs as underlying layer and watch
    the fireworks. There may be a non-trivial amount of state associated with
    current IO position, well beyond the numeric offset. Using the single
    struct file associated with underlying inode is really not a good idea;
    we ought to open one for each ecryptfs directory struct file.

    Additionally, file_operations both for directories and non-directories are
    full of pointless methods; non-directories should *not* have ->iterate(),
    directories should not have ->flush(), ->fasync() and ->splice_read().

  • PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
    ago with promise that one day it will be possible to implement page
    cache with bigger chunks than PAGE_SIZE.

    This promise never materialized. And unlikely will.

    We have many places where PAGE_CACHE_SIZE assumed to be equal to
    PAGE_SIZE. And it's constant source of confusion on whether
    PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
    especially on the border between fs and mm.

    Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
    breakage to be doable.

    Let's stop pretending that pages in page cache are special. They are
    not.

    The changes are pretty straight-forward:

    - << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> ;

    - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

    - page_cache_get() -> get_page();

    - page_cache_release() -> put_page();

    This patch contains automated changes generated with coccinelle using
    script below. For some reason, coccinelle doesn't patch header files.
    I've called spatch for them manually.

    The only adjustment after coccinelle is revert of changes to
    PAGE_CAHCE_ALIGN definition: we are going to drop it later.

    There are few places in the code where coccinelle didn't reach. I'll
    fix them manually in a separate patch. Comments and documentation also
    will be addressed with the separate patch.

  • Mark those kmem allocations that are known to be easily triggered from
    userspace as __GFP_ACCOUNT/SLAB_ACCOUNT, which makes them accounted to
    memcg. For the list, see below:

    - threadinfo
    - task_struct
    - task_delay_info
    - pid
    - cred
    - mm_struct
    - vm_area_struct and vm_region (nommu)
    - anon_vma and anon_vma_chain
    - signal_struct
    - sighand_struct
    - fs_struct
    - files_struct
    - fdtable and fdtable->full_fds_bits
    - dentry and external_name
    - inode for all filesystems. This is the most tedious part, because
    most filesystems overwrite the alloc_inode method.

    The list is far from complete, so feel free to add more objects.
    Nevertheless, it should be close to "account everything" approach and
    keep most workloads within bounds. Malevolent users will be able to
    breach the limit, but this was possible even with the former "account
    everything" approach (simply because it did not account everything in
    fact).

    with that. I really should've asked for moratorium on lookup-related
    changes this cycle, but since I hadn't done that early enough... I
    *am* asking for that for the coming cycle, though - I'm going to try
    and get conversion of i_mutex to rwsem with ->lookup() done under lock
    taken shared.

    There will be a patch closer to the end of the window, along the lines
    of the one Linus had posted last May - mechanical conversion of
    ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
    inode_is_locked()/inode_lock_nested(). To quote Linus back then:

    -----
    | This is an automated patch using
    |
    | sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
    | sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
    | sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[ ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
    | sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
    | sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
    |
    | with a very few manual fixups
    -----

    I'm going to send that once the ->i_mutex-affecting stuff in -next
    gets mostly merged (or when Linus says he's about to stop taking
    merges)"
