Thanks to Josef Bacik for finding these.

A couple of ecryptfs error paths don't properly unlock things they locked.

ecryptfs: fix string overflow on long cipher names

2007-12-23T20:54:36+00:00

Passing a cipher name > 32 chars on mount results in an overflow when the
cipher name is printed, because the last character in the struct
ecryptfs_key_tfm's cipher_name string was never zeroed.

eCryptfs: increment extent_offset once per loop interation

2007-11-05T23:12:33+00:00

The extent_offset is getting incremented twice per loop iteration through any
given page.  It should only be getting incremented once.  This bug should only
impact hosts with >4K page sizes.

[CRYPTO] users: Fix up scatterlist conversion errors

2007-10-27T07:52:07+00:00

This patch fixes the errors made in the users of the crypto layer during
the sg_init_table conversion.  It also adds a few conversions that were
missing altogether.

SG: Change sg_set_page() to take length and offset argument

2007-10-24T09:20:47+00:00

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.

Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

ecryptfs: clean up page flag handling

2007-10-16T16:43:12+00:00

The functions that eventually call down to ecryptfs_read_lower(),
ecryptfs_decrypt_page(), and ecryptfs_copy_up_encrypted_with_header()
should have the responsibility of managing the page Uptodate
status. This patch gets rid of some of the ugliness that resulted from
trying to push some of the page flag setting too far down the stack.

eCryptfs: remove unused functions and kmem_cache

2007-10-16T16:43:12+00:00

The switch to read_write.c routines and the persistent file make a number of
functions unnecessary.  This patch removes them.
