eCryptfs: fix 32 bit corruption issue

2013-10-24T19:36:30Z

Shifting page->index on 32 bit systems was overflowing, causing data corruption of > 4GB files. Fix this by casting it first. https://launchpad.net/bugs/1243636 Signed-off-by: Colin Ian King Reported-by: Lars Duesing Cc: stable@vger.kernel.org # v3.11+ Signed-off-by: Tyler Hicks

ecryptfs: Fix memory leakage in keystore.c

ecryptfs: avoid ctx initialization race

2013-09-06T23:58:18Z

It might be possible for two callers to race the mutex lock after the NULL ctx check. Instead, move the lock above the check so there isn't the possibility of leaking a crypto ctx. Additionally, report the full algo name when failing. Signed-off-by: Kees Cook [tyhicks: remove out label, which is no longer used] Signed-off-by: Tyler Hicks

ecryptfs: remove check for if an array is NULL

2013-09-06T23:51:56Z

It doesn't make sense to check if an array is NULL. The compiler just removes the check. Signed-off-by: Dan Carpenter Signed-off-by: Tyler Hicks

Merge tag 'ecryptfs-3.11-rc1-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs

2013-07-11T17:20:18Z

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" * tag 'ecryptfs-3.11-rc1-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: Use ecryptfs_dentry_to_lower_path in a couple of places eCryptfs: Make extent and scatterlist crypt function parameters similar eCryptfs: Collapse crypt_page_offset() into crypt_extent() eCryptfs: Merge ecryptfs_encrypt_extent() and ecryptfs_decrypt_extent() eCryptfs: Combine page_offset crypto functions eCryptfs: Combine encrypt_scatterlist() and decrypt_scatterlist() eCryptfs: Decrypt pages in-place eCryptfs: Accept one offset parameter in page offset crypto functions eCryptfs: Simplify lower file offset calculation eCryptfs: Read/write entire page during page IO eCryptfs: Use entire helper page during page crypto operations eCryptfs: Cocci spatch "memdup.spatch"

Use ecryptfs_dentry_to_lower_path in a couple of places

2013-07-10T06:40:28Z

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). Signed-off-by: Matthew Wilcox Signed-off-by: Tyler Hicks

[readdir] introduce iterate_dir() and dir_context

2013-06-29T08:46:46Z

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.
