tools: env: Add support for direct read/write UBI volumes

2017-11-30T03:30:50+00:00

Up to now we were able to read/write environment data from/to UBI
volumes only indirectly by gluebi driver. This driver creates NAND MTD
on top of UBI volumes, which is quite a workaroung for this use case.

Add support for direct read/write UBI volumes in order to not use
obsolete gluebi driver.

tools: env: allow to print U-Boot version

2017-11-06T14:58:59+00:00

The fw_env utility family has a default environment compiled in
which ties it quite strongly to the U-Boot source/config it has
been built with. Allow to display the U-Boot version it has been
built with using the -v/--version argument.

env: Fix operation of 'make environ'

2017-09-06T00:34:08+00:00

This was broken by the recent environment refactoring. Specifically:

$  make environ
scripts/Makefile.build:59: tools/environ/Makefile: No such file or directory
make[1]: *** No rule to make target 'tools/environ/Makefile'.  Stop.
make: *** [Makefile:1469: environ] Error 2

Fix this by updating the Makefile and adjusting the #include filesnames in
two C files.

Fixes: ec74f5f (Makefile: Rename 'env' target to 'environ')

env: Fix out of tree building of tools-all

2017-09-05T19:59:47+00:00

With the move of environment code from common/ to env/ a number of
changes needed to be made to various make targets.  We missed updating
some of the files required for out of tree builds of the tools.  Correct
the 'environ' target to know that we need to work under tools/env/ still
(not tools/environ/) and then update the wrappers in env_attr.c and
env_flags.c to point to the new correct file.

fix: fw_env: Prevent writing error message on special files, which don't support fsync

2017-09-03T19:30:31+00:00

According to fsync specification [1] some special files (e.g., a pipe, FIFO,
or socket) don't support synchronization and return either EROFS or EINVAL.

On the linux side the sys_fsync -> do_fsync() checks if the requested file
has f_op->fsync defined. If not it returns EINVAL [2].

This commit prevents writing error messages for files (devices), which
do not support fsync().

env: Rename setenv() to env_set()

2017-08-16T12:22:18+00:00

We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.

tools/fw_env: use fsync to ensure that data is physically stored

2017-07-22T19:36:16+00:00

Closing a file descriptor does not guarantee that the data has been
successfully saved to disk, as the kernel might defer the write.
