| * ratp: Fix closing connectionsSascha Hauer2020-06-161-0/+2
| | | | | | | | | | | | | | | | | | | | When entering the LAST_ACK state we have to set the saved SN to the received SN of the current packet. With this we properly accept the final incoming packet and close the connection. Without this we interpret the final incoming packet as a duplicate of the previous packet and close the connection only after a timeout. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | discard range is called with unitialized size argument. Call it after stat() on the source filedescriptor. Also there's no point in continuing when stat() on the source filedescriptor fails, so bail out in this case. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | list_sort.c's core code should only change on sync with Linux, so we don't really need separate testing code. The code doesn't compile as we neither have a CONFIG_TEST_LIST_SORT symbol nor do we have a <linux/random.h> header. Remove it.

* / fs: fat: extend for in-PBL supportAhmad Fatoum2020-07-111-1/+1
|/ | | | | | | | | | | The AT91 BootROM loads a boot.bin file from the first FAT partition into SRAM, when booting from MMC. To avoid the need for two barebox configurations for each of the bootloader stages, add PBL support for reading from FAT. This way each stage need only have a different PBL entry point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is can be considered an extension to the dev_add_param_bool interfaces with a third value that's "unknown". This can be used for cases, where barebox can flip a bit somewhere, but it has no way of knowing what the initial state of the bit was, e.g. turn on/off the watchdog, but no watchdog status. Turn on/off a co-processor, but no co-processor online status. And so on. Not providing a way to customize the "unknown" string is a deliberate choice, so future device parameters follow the same naming scheme.

* parameter: strip leading and trailing whitespacesMarco Felsch2019-11-041-1/+4
| | | | | | | | | | | | | | | | | My initial bug was the following: I set the global.boot.default="boot1 boot2 " and executed the 'boot' command. If both targets are not bootable barebox starts to execute the boot scripts found under /env/boot. This is because of the command/boot.c implementation and the leading whitespace. Without the whitespace only the two desired boot targets are tried. IMHO leading and trailing whitespaces are error-prone in many cases. If someone wants to concatenate strings he/she should add spaces on purpose. So I fixed the bug above globally by always stripping leading and trailing whitespaces.

* common: ubsan: ignore shifting one into sign bitAhmad Fatoum2019-10-141-0/+20
| | | | | | | | | | | | | The __ubsan_handle_shift_out_of_bounds handler would be called for code shifting a one into the sign bit like (1 << 31), which is all too common in barebox. It's technically UB, but it's so prevalent that it's highly unlikely to be treated by a compiler as anything else than the standard-compliant (1U << 31). Check for this case here and ignore it selectively. Signed-off-by: Ahmad Fatoum <ahmad@a3f.at> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Convert latin1 files to utf-8Uwe Kleine-König2019-10-143-384/+384
| | | | | | | | | | | The source files are parsed by $(make docs). Currently this is done using python2 (actually 'python' which is still python2 on most machines). When using python3 however (which has a stricter encoding handling) it is easier if all input is in utf-8 encoding. So convert the few remaining latin1 encoded files to utf-8. This only affects code comments. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far (p|)write_full has been returning -1 on error. Some callers of write_full like imx_bbu_write_device print out the function's return value on error, effectively rendering every printed error message to be due to EPERM. On the other hand, some callers like do_memcpy, use it correctly and use errno. Sidestep the issue by having the function return -errno on errors as well.
