* login: check return value of digest_allocSascha Hauer2015-08-281-0/+4
| | | | | | digest_alloc can fail, check the return value. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* login: cleanup password codeSascha Hauer2015-08-281-39/+9
| | | | | | | | - make some locally used functions static - remove read_passwd which is unused - some refactoring to make code pathes clearer Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* login: rework login mechanismSascha Hauer2015-08-281-2/+73
| | | | | | | | | | | | | | We used to have the login functionality in the /env/bin/init script. This is hard to review and it's too easy to break the login functionality with changes to this script. Move the places to ask for a password to C code where we have only a few places where we have to ask for a password. Mainly these are run_shell() and the menutree command. This patch introduces a login() function which will only return if the correct password has been entered. Following calls will return immediately without asking for a password again.

* password: add pbkdf2 supportJean-Christophe PLAGNIOL-VILLARD2015-03-201-30/+66

* digest: make it multi-instanceJean-Christophe PLAGNIOL-VILLARD2015-03-121-2/+3
| | | | | | | | | | Now you need to call digest_alloc and when you finish to use it digest_free. We need this for upcomming aes encryption support and secure boot as we will need multiple instance of the same digest.

* digest: introduce digest_{init/update/final/length}Jean-Christophe PLAGNIOL-VILLARD2015-03-121-13/+13
