2019-09-02	75a74b5 Browse files » console: fix out-of-bounds read in dputc(/dev/*, ...) ... Trying to output a single character via echo -a /dev/serial0-1 currently results in garbage output after the newline, because console.c's fops_write discards the buffer length and passes the buffer to (struct cdev)::puts which only handles NUL-terminated strings. Fix this by amending (struct cdev)::puts with a new nbytes parameter, which is correctly propagated. All this functions now return at most the nbytes parameter they were passed in. This fixes __console_puts, which used to count new lines twice in its return value.

2019-04-24	ec5f3d3 Browse files » console: forbid ctrlc during startup ... When global.autoboot_abort_key is set to ctrl-c then the user is expected to press ctrl-c to get to the prompt. The user might press ctrl-c before the init script runs the "timeout" command. In this case the init script is aborted at arbitrary places which leads to inconsistent results depending on the place it is aborted. This patch introduces the global.console.ctrlc_allowed variable. When this variable is set to false ctrl-c is ignored entirely. The variable is set to false by default and changed to true in the init script.

2018-04-17	84fc611 Browse files » console: Introduce console_drain() ... Generalize high baud rate UART polling code found in lib/xmodem.c and expose it as a generic function in console API. The usecase for this -- besides X/Y-mode data transfers where the code originated -- is command/reply type of serial exchages at high baud rates (~1Mbaud) with payloads exceeding inernal UART FIFOs in size. Such interactions are not uncommon in serdev device and this patch is done in preparation for serdev support code that will follow.

2015-08-28	90e766a Browse files » login: rework login mechanism ... 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.

This makes the PBL console independent of DEBUG_LL which is only meant for early debugging but not regular output. To use the regular PBL console a board must call pbl_set_putc() which stores a pointer to the putc function to be used.

2014-01-22	dac65f9 Browse files » console: Set Linux console parameter automatically ... Linux specifies the linux,stdout-path property in the /chosen node in the devicetree. Unfortunately this is ignored in most cases. For cases in which barebox uses this property for its own use we translate this into a Linux boot arg with: - the console name provided by the serial driver - the the instance from the 'serial' alias - the baudrate from the actual baudrate. So with this it's for devicetee enabled boards no longer necessary to manually assign a console= parameter. Should a user not want to use the automatically assigned parameter it should do: global.linux.bootargs.console= in the environment.
