eCryptfs: fix 32 bit corruption issue

2013-11-13T03:08:08+00:00

commit 43b7c6c6a4e3916edd186ceb61be0c67d1e0969e upstream.

Shifting page->index on 32 bit systems was overflowing, causing
data corruption of > 4GB files. Fix this by casting it first.

Pull eCryptfs updates from Tyler Hicks:
 "Code cleanups and improved buffer handling during page crypto
  operations:
   - Remove redundant code by merging some encrypt and decrypt functions
   - Get rid of a helper page allocation during page decryption by using
     in-place decryption
   - Better use of entire pages during page crypto operations
   - Several code cleanups"

Use ecryptfs_dentry_to_lower_path in a couple of places

2013-07-10T06:40:28+00:00

There are two places in ecryptfs that benefit from using
ecryptfs_dentry_to_lower_path() instead of separate calls to
ecryptfs_dentry_to_lower() and ecryptfs_dentry_to_lower_mnt().  Both
sites use fewer instructions and less stack (determined by examining
objdump output).

[readdir] introduce iterate_dir() and dir_context

2013-06-29T08:46:46+00:00

iterate_dir(): new helper, replacing vfs_readdir().

struct dir_context: contains the readdir callback (and will get more stuff
in it), embedded into whatever data that callback wants to deal with;
eventually, we'll be passing it to ->readdir() replacement instead of
(data,filldir) pair.

eCryptfs: Make extent and scatterlist crypt function parameters similar

2013-06-08T00:28:29+00:00

The 'dest' abbreviation is only used in crypt_scatterlist(), while all
other functions in crypto.c use 'dst' so dest_sg should be renamed to
dst_sg.

The crypt_stat parameter is typically the first parameter in internal
eCryptfs functions so crypt_stat and dst_page should be swapped in
crypt_extent().

eCryptfs: Collapse crypt_page_offset() into crypt_extent()

2013-06-08T00:28:28+00:00

crypt_page_offset() simply initialized the two scatterlists and called
crypt_scatterlist() so it is simple enough to move into the only
function that calls it.
