* console: Fix console_get_first_active()Andrey Smirnov2018-06-191-1/+2
| | | | | | | | Fix if condition in console_get_first_active() to actually check that both bit are set. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: added colored print out of log levelsEugen Wiens2018-02-221-0/+25
| | | | | | | When the system is booting the warnings and errors are not be quickly discovered. With this improvement the errors are colored red, the warnings yellow and the notices blue. Signed-off-by: Eugen Wiens <eugen.wiens@jumo.net> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: move global.allow_color handling to C codeSascha Hauer2018-02-221-2/+15
| | | | | | | | | We have global.allow_color, but this is limited to the environment only. Move creation and handling of this variable to C code so that we can add support for colored output to commands/console controlled by the same variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Revert "globalvar: make globalvar functions more consistent"Sascha Hauer2017-06-131-3/+3

* globalvar: make globalvar functions more consistentSascha Hauer2017-04-111-3/+3
| | | | | | | | | 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>
* console: console_get_by_name: do not strcmp NULLAlexander Kurz2017-03-291-1/+1
| | | | | | | | | | | | | console_get_by_name iterates through the console_list using strcmp to mach a given console by name. console_list may contain entries with devname = NULL, inserted there e.g. by KEYBOARD_GPIO. In worst case loady -t usbserial will crash barebox when strcmp hits 0 NULL devname: > unable to handle NULL pointer dereference at address 0x00000000 Let console_get_by_name just ignore the anonymous consoles.

* stdio: Replace FILE functions with filedescriptor functionsSascha Hauer2016-04-151-9/+9
| | | | | | | | | | | | We have defined stdin, stdout and stderr as integer file descriptors, but normally they should be FILE *. Also fprintf, fputc and fputs take file descriptors instead of FILE *. As FILE * are inconvenient in the barebox environment replace the f* functions with the corresponding d* functions. dprintf is POSIX conform whereas dputc and dputs are barebox specific, but do not conflict with any stdc function. fgetc is unused and can be removed without replacing it.

* console: use int rather than uint in printf() and friendsMasahiro Yamada2015-09-071-3/+3
| | | | | | | | These functions and vsprintf() return int type. No reason to use uint type. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* login: rework login mechanismSascha Hauer2015-08-281-27/+0
| | | | | | | | | | | | | | 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.

| * console: use regular malloc for log messagesSascha Hauer2015-05-151-3/+11
| | | | | | | | | | | | | | | | Using xfunctions to allocate log messages is not a good idea. Should we be out of memory the xfunctions will panic which will cause another allocation, so we deadlock the system with no message going out. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | console: Add console_get_by_nameSascha Hauer2015-06-091-0/+13

* console: Make sure xzalloc is only used when it's availableSascha Hauer2015-01-051-1/+1
| | | | | | | | To make it possible to call the pr_* functions very early before malloc is initialized test if malloc is available before using it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Introduce message logging supportSascha Hauer2014-09-301-3/+126
| | | | | | | | | | This adds a buffer for log messages and a 'dmesg' command to print the messages. The log buffer is implemented as log objects rather than a string buffer. This makes it easy to implement limiting the messages, cleaning the buffer and timestamping the messages. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
