* globalvar: make globalvar functions more consistentSascha Hauer2017-04-111-1/+1
| | | | | | | | | Similar to the device parameter functions also make the globalvar functions more consistent. This also adds support for readonly globalvars and changes several existing globalvars which should really be readonly to readonly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* common: password: make use of get_crypto_bytesOleksij Rempel2017-03-301-1/+5
| | | | | | | | get_random_bytes is providing prng, if we have HWRNG we should be able to use it over get_crypto_bytes Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* stdio: rename getc to getcharSascha Hauer2016-04-151-1/+1
| | | | | | | The function we have implemented as getc has the semantics of the standard function getchar, so rename it accorgingly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* include: move run_command prototype to command.hSascha Hauer2016-04-151-0/+1
| | | | | | run_command fits much better into command.h, move it there. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* 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.
