The new Kconfig option, defaulting to N, allows the rarely used eCryptfs kernel to userspace communication channel to be compiled out. This may be the first step in it being eventually removed." Hmm. I'm not sure whether these should be called "fixes", and it probably should have gone in the merge window. But I'll let it slide. * tag 'ecryptfs-3.9-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: allow userspace messaging to be disabled eCryptfs: Fix redundant error check on ecryptfs_find_daemon_by_euid() ecryptfs: ecryptfs_msg_ctx_alloc_to_free(): remove kfree() redundant null check eCryptfs: decrypt_pki_encrypted_session_key(): remove kfree() redundant null check eCryptfs: remove unneeded checks in virt_to_scatterlist() eCryptfs: Fix -Wmissing-prototypes warnings eCryptfs: Fix -Wunused-but-set-variable warnings eCryptfs: initialize payload_len in keystore.c
| * eCryptfs: allow userspace messaging to be disabledKees Cook2013-03-031-0/+8
| | | | | | | | | | | | | | | | | | | | When the userspace messaging (for the less common case of userspace key wrap/unwrap via ecryptfsd) is not needed, allow eCryptfs to build with it removed. This saves on kernel code size and reduces potential attack surface by removing the /dev/ecryptfs node.

* | fs/ecryptfs: remove depends on CONFIG_EXPERIMENTALKees Cook2013-01-111-2/+2
|/ | | | | | | | | | | The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

* eCryptfs: fix compile errorRoberto Sassu2011-08-091-1/+1
| | | | | | | | | | | | | | This patch fixes the compile error reported at the address: https://bugzilla.kernel.org/show_bug.cgi?id=40292 The problem arises when compiling eCryptfs as built-in and the 'encrypted' key type as a module. The patch prevents this combination from being set in the kernel configuration, by fixing the eCryptfs dependencies.

* eCryptfs: Remove Kconfig NET dependency and select MD5Tyler Hicks2009-10-081-1/+2
| | | | | | | | | eCryptfs no longer uses a netlink interface to communicate with ecryptfsd, so NET is not a valid dependency anymore. MD5 is required and must be built for eCryptfs to be of any use. Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
* ecryptfs: depends on CRYPTORandy Dunlap2009-10-081-1/+1
| | | | | | | | | | ecryptfs uses crypto APIs so it should depend on CRYPTO. Otherwise many build errors occur.

* ecryptfs: improved dependency checking and reportingDave Hansen2009-09-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So, I compiled a 2.6.31-rc5 kernel with ecryptfs and loaded its module. When it came time to mount my filesystem, I got this in dmesg, and it refused to mount: [93577.776637] Unable to allocate crypto cipher with name [aes]; rc = [-2] [93577.783280] Error attempting to initialize key TFM cipher with name = [aes]; rc = [-2] [93577.791183] Error attempting to initialize cipher with name = [aes] and key size = [32]; rc = [-2] [93577.800113] Error parsing options; rc = [-22] I figured from the error message that I'd either forgotten to load "aes" or that my key size was bogus. Neither one of those was the case. In fact, I was missing the CRYPTO_ECB config option and the 'ecb' module. Unfortunately, there's no trace of 'ecb' in that error message. I've done two things to fix this. First, I've modified ecryptfs's Kconfig entry to select CRYPTO_ECB and CRYPTO_CBC. I also took CRYPTO out of the dependencies since the 'select' will take care of it for us. I've also modified the error messages to print a string that should contain both 'ecb' and 'aes' in my error case. That will give any future users a chance of finding the right modules and Kconfig options. I also wonder if we should: select CRYPTO_AES if !EMBEDDED since I think most ecryptfs users are using AES like me.
