[PATCH] Fix HFS+ to free up the space when a file is deleted.

2005-10-26T17:39:43+00:00

fsck_hfs reveals lots of temporary files accumulating in the hidden
directory "\000\000\000HFS+ Private Data".  According to the HFS+
documentation these are files which are unlinked while in use.  However,
there may be a bug in the Linux hfsplus implementation which causes this to
happen even when the files are not in use.  It looks like the "opencnt"
field is never initialized as (I think) it should be in hfsplus_read_inode.
 This means that a file can appear to be still in use when in fact it has
been closed.  This patch seems to fix it for me.

[PATCH] inotify/idr leak fix

2005-10-23T23:38:39+00:00

Fix a bug which was reported and diagnosed by
Stefan Jones 

IDR trees include a cache of idr_layer objects.  There's no way to destroy
this cache, so when we discard an overall idr tree we end up leaking some
memory.

Add and use idr_destroy() for this.  v9fs and infiniband also need to use
idr_destroy() to avoid leaks.

Or, we make the cache global, like radix_tree_preload().  Which is probably
better.  Later.

[PATCH] aio syscalls are not checked by lsm

2005-10-23T23:38:38+00:00

Another case of missing call to security_file_permission: aio functions
(namely, io_submit) does not check credentials with security modules.

Below is the simple patch to the problem.  It seems that it is enough to
check for rights at the request submission time.

[PATCH] aio: revert lock_kiocb()

2005-10-18T00:03:57+00:00

lock_kiocb() was introduced to serialize retrying and cancellation.  In the
process of doing so it tried to sleep waiting for KIF_LOCKED while holding
the ctx_lock spinlock.  Recent fixes have ensured that multiple concurrent
retries won't be attempted for a given iocb.  Cancel has other problems and
has no significant in-tree users that have been complaining about it.  So
for the immediate future we'll revert sleeping with the lock held and will
address proper cancellation and retry serialization in the future.

[PATCH] output of /proc/maps on nommu systems is incomplete

2005-10-18T00:03:57+00:00

Currently you do not get all the map entries on nommu systems because the
start function doesn't index into the list using the value of "pos".

[PATCH] NFS: Fix Oopsable/unnecessary i_count manipulations in nfs_wait_on_inode()

2005-10-17T21:47:16+00:00

Oopsable since nfs_wait_on_inode() can get called as part of iput_final().

Unnecessary since the caller had better be damned sure that the inode won't
disappear from underneath it anyway.

[PATCH] NFS: Fix cache consistency races

2005-10-17T21:47:16+00:00

If the data cache has been marked as potentially invalid by nfs_refresh_inode,
we should invalidate it rather than assume that changes are due to our own
activity.

Also ensure that we always start with a valid cache before declaring it
to be protected by a delegation.

[PATCH] binfmt_elf bss padding fix

2005-10-11T16:46:54+00:00

Nir Tzachar  points out that if an ELF file specifies a
zero-length bss at a whacky address, we cannot load that binary because
padzero() tries to zero out the end of the page at the whacky address, and
that may not be writeable.

See also http://bugzilla.kernel.org/show_bug.cgi?id=5411

So teach load_elf_binary() to skip the bss settng altogether if the elf file
has a zero-length bss segment.

[PATCH] nfsacl: Solaris VxFS compatibility fix

2005-10-11T16:46:54+00:00

Here is a compatibility fix between Linux and Solaris when used with VxFS
filesystems: Solaris usually accepts acl entries in any order, but with
VxFS it replies with NFSERR_INVAL when it sees a four-entry acl that is not
in canonical form.  It may also fail with other non-canonical acls -- I
can't tell, because that case never triggers: We only send non-canonical
acls when we fake up an ACL_MASK entry.

Instead of adding fake ACL_MASK entries at the end, inserting them in the
correct position makes Solaris+VxFS happy.  The Linux client and server
sides don't care about entry order.  The three-entry-acl special case in
which we need a fake ACL_MASK entry was handled in xdr_nfsace_encode.  The
patch moves this into nfsacl_encode.
