2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-10fw_printenv: Fix crash due to incorrect size for malloc'ed string.Kristian Amlie
Using sizeof gives the size of the pointer only, not the string. This could easily lead to crashes when using -l argument. Signed-off-by: Kristian Amlie <kristian.amlie@northern.tech>
2018-02-14Fix --noheader on fw_printenvAlex Kiernan
The single argument `--noheader' is expecting isn't taken from getopt parsing, but instead from the remaining argv arguments. Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com>
2017-11-21env: Remove CONFIG_ENV_AES supportTom Rini
This support has been deprecated since v2017.09 due to security issues. We now remove this support. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-11-06tools: env: allow to print U-Boot versionStefan Agner
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. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Reviewed-by: Lukasz Majewski <lukma@denx.de>
2017-08-16env: Rename setenv() to env_set()Simon Glass
We are now using an env_ prefix for environment functions. Rename setenv() for consistency. Also add function comments in common.h. Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-12env: split fw_env.h in public and private partsStefano Babic
Move U-Boot private data into a separate file. This lets export fw_env.h to be used by external programs that want to change the environment using the library built in tools/env. Signed-off-by: Stefano Babic <sbabic@denx.de>
2016-10-08env: tool: add command line option to input lockfile pathB, Ravi
The default lockname is set to /var/lock. This limits the usage of this application where OS uses different lockfile location parameter. For example, In case of android, the default lock path location is /data. Hence by providing the command line option to input lockfile path will be useful to reuse the tool across multiple operating system. usage: ./fw_printenv -l <lockfile path> Signed-off-by: Ravi Babu <ravibabu@ti.com>

2015-11-18tools/env: allow config filename to be passed via command line argumentMichael Heimpold
When for example generating/manipulating SD card/eMMC images which contain U-Boot and its environment(s), it is handy to use a given configuration file instead of the compiled-in default one. And since the default configuration file is expected under /etc it's hard for an usual linux user account without special permissions to use fw_printenv/fw_setenv for this purpose. So allow to pass an optional filename via a new '-c' command line argument. Example: $ ln -s fw_printenv tools/env/fw_setenv $ cat fw_env.config test.img 0x20000 0x20000 test.img 0x40000 0x20000 $ tools/env/fw_printenv -c ./fw_env.config fdt_file fdt_file=imx28-duckbill.dtb $ tools/env/fw_setenv -c ./fw_env.config fdt_file imx28-duckbill-spi.dtb $ tools/env/fw_printenv -c ./fw_env.config fdt_file fdt_file=imx28-duckbill-spi.dtb Signed-off-by: Michael Heimpold <mhei@heimpold.de>
2014-03-21env: Implement support for AES encryption into fw_* toolsMarek Vasut
Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.

When using open(), the O_CREAT flag must be given a mode, otherwise it uses random garbage from the stack. Also, it can fail to build: In file included from /usr/include/fcntl.h:290:0, from fw_env_main.c:42: In function 'open', inlined from 'main' at fw_env_main.c:97:9: /usr/include/bits/fcntl2.h:50:24: error: call to '__open_missing_mode' declared with attribute error: open with O_CREAT in second argument needs 3 arguments Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

2010-09-18tools/env: allow option "-n" for fw_printenvDaniel Hobi
In commit bd7b26f8 (Tools: set multiple variable with fw_setenv utility), the option parsing was changed to getopt_long(3), but option "-n" of fw_printenv was not included. This leads to an error message "invalid option -- 'n'" on stderr, although the output on stdout is correct. Signed-off-by: Daniel Hobi <daniel.hobi@schmid-telecom.ch>
2010-06-29Tools: set multiple variable with fw_setenv utilityStefano Babic
