Mark or fix switch cases that fall through

2017-11-02T00:34:18+00:00

Now that C++17 introduced a special fallthrough keyword for explicitly tagging switch cases that are supposed to fall through, newer gcc versions also implement a feature request from 2002 to warn about maybe unwanted fall-throughs in switch cases in other languages (like C). For C code, we can either add a gcc specific attribute at the end of the switch case, or use a special comment that gcc checks for, indicating that the fall-through behaviour is indeed intended. This patch adds a "/* fall-through */" comment at the end of various case blocks to silence gcc warnings and in some cases a break, where fall-through was probably not intended.

ubi-utils: Return error code if command line option is unknown

2017-06-14T09:00:30+00:00

The tools in question will quit with an exit code 0 if the command line option was not recognized. By returning an error code a calling script has the possibility to distinguish between a real success and an invalid invocation. We need to return -1 instead of EXIT_FAILURE to be consistent with the other exit code places. Signed-off-by: Daniel Wagner Signed-off-by: David Oberhollenzer

ubi-utils: Add ubiblock tool

2014-03-25T07:54:48+00:00

With the addition of block device access to UBI volumes, we now add a simple userspace tool to access the new ioctls. Usage of this tool is as simple as it gets: $ ubiblock --create /dev/ubi0_0 will create a new block device /dev/ubiblock0_0, and $ ubiblock --remove /dev/ubi0_0 will remove the device. Artem: slightly changed the header comment. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy
