* nvvar: Fix creation without valueSascha Hauer2017-04-071-3/+9
| | | | | | | | | | When a new nvvar is added without a value we want to get the value from the corresponding globalvar. We do this by using nv_set which ends up freeing the exact string that we passed into nv_set as value. This results in a corrupt value. Fix this by assigning a value manually without calling nv_set.

* console: fix usbserial re-connectAlexander Kurz2017-03-291-1/+3
| | | | | | | | | | | | | | | | With commit b4f55fcf355a ("console: expose consoles in devfs") consoles got inserted, but never removed from devfs. When dealing with USB consoles, barebox should be prepared for devices spontaneously appering and disappering again (user disconnects and re- connects the cable). If the devfs entry is not removed upon disconnect, barebox will raise an error "device creation failed with File exists" when the cable is connected again. Remove devfs entries when consoles are de-registered. Also change the error message, it's the devfs entry.

* 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.

| | | | | | | | | | | | | | | | | | | | | | Some drivers need an explicit sync method to flush the virtual framebuffer to the display.

| * | usb: gadget: properly release f_multi_optsSascha Hauer2017-03-093-8/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usbgadget commands uses statically allocated f_multi_opts and passes this to usb_multi_register(). These f_multi_opts are of course no longer valid when we leave the usbgadget command. Luckily we do not use the data after we left the usbgadget command, so this never has been a problem. However, f_multi_opts has some allocated members which we can not free anymore on gadget unregistration because we no longer have the pointer to them. Fix this by adding a release function to struct f_multi_opts. This way we can allocate all memory dynamically and properly free it when not used anymore.
