2018-07-20cmd: nvedit: env import can now import only variables passed as parametersQuentin Schulz
While the `env export` can take as parameters variables to be exported, `env import` does not have such a mechanism of variable selection. Let's add the ability to add parameters at the end of the command for variables to be imported. Every env variable from the env to be imported passed by parameter to this command will override the value of the variable in the current env. If a variable exists in the current env but not in the imported env, if this variable is passed as a parameter to env import, the variable will be unset ONLY if the -d option is passed to env import, otherwise the current value of the variable is kept. If a variable exists in the imported env, the variable in the current env will be set to the value of the one from the imported env. All the remaining variables are left untouched. As the size parameter of env import is positional but optional, let's add the possibility to use the sentinel '-' for when we don't want to give the size parameter (when the env is '\0' terminated) but we pass a list of variables at the end of the command. env import addr env import addr - env import addr size env import addr - foo1 foo2 env import addr size foo1 foo2 are all valid. env import -c addr env import -c addr - env import -c addr - foo1 foo2 are all invalid because they don't pass the size parameter required for checking, while the following are valid. env import addr size env import addr size foo1 foo2 Nothing's changed for the other parameters or the overall behaviour. One of its use case could be to load a secure environment from the signed U-Boot binary and load only a handful of variables from an other, unsecure, environment without completely losing control of U-Boot.

2018-07-19env: common: accept flags on reset to default envYaniv Levinsky
The function set_default_env() sets the hashtable flags for import_r(). Formally set_default_env() doesn't accept flags from its callers. In practice the caller can (un)set the H_INTERACTIVE flag, but it has to be done using the first character of the function's string argument. Other flags like H_FORCE can't be set by the caller. Change the function to accept flags argument. The benefits are: 1. The caller will have to explicitly set the H_INTERACTIVE flag, instead of un-setting it using a special char in a string. 2. Add the ability to propagate flags from the caller to himport(), especially the H_FORCE flag from do_env_default() in nvedit.c that currently gets ignored for "env default -a -f" commands. 3. Flags and messages will not be coupled together. A caller will be able to set flags without passing a string and vice versa. Please note: The propagation of H_FORCE from do_env_default() does not introduce any functional changes, because currently himport_r() is set to destroy the old environment regardless if H_FORCE flag is set or not. More changes are needed to utilize the propagation of H_FORCE. Signed-off-by: Yaniv Levinsky <yaniv.levinsky@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2018-07-19cmd: nvedit: set H_INTERACTIVE in do_env_defaultYaniv Levinsky
The function set_default_vars() in common.c adds H_INTERACTIVE to the h_import() flag, but the function has no way of telling if the command actually was user directed like this flag suggest. The flag should be set by the calling function do_env_default() in nvedit.c instead, where the command is certainty user directed. Move the H_INTERACTIVE flag from set_default_vars() to do_env_default(). Signed-off-by: Yaniv Levinsky <yaniv.levinsky@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2018-07-19cmd: nvedit: propagate envflag to set_default_varsYaniv Levinsky
The env_flag in do_env_default() doesn't get propagated and therefore gets ignored by himport_r(). This breaks to ability to "forcibly" reset variables to their default values using the environment command. Scenario example of the problem: # setenv kernel uImage # setenv .flags kernel:so # env default -f kernel ## Error: Can't overwrite "kernel" himport_r: can't insert "kernel=zImage" into hash table Change the call path so it will pass the flag correctly.

2018-07-19cmd: nvedit: rename flags in do_env_defaultYaniv Levinsky
The naming convention for flags in nvedit.c is: * The hashtable flag (defined in search.h) is named "env_flag" * The command flag argument (defined in command.h) is named "flag" This convention is kept in functions like do_env_print(), do_env_set() and do_env_delete(), but not in do_env_default(). Rename the hashtable flag in do_env_default() from "flag" to "env_flag". Rename the command flag in do_env_default() from "__flag" to "flag". No functional change.

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>
2018-04-08net: Move enetaddr env access code to env config instead of net configAlex Kiernan

2018-01-31cmd: nvedit: env_get_f must check for env_get_char error codesSimon Goldschmidt
env_get_f calls env_get_char to load single characters from the environment. However, the return value of env_get_char was not checked for errors. Now if the env driver does not support the .get_char call, env_get_f did not notice this and looped over the whole size of the environment, calling env_get_char over 8000 times with the default settings, just to return an error in the end. Fix this by checking if env_get_char returns < 0. Signed-off-by: Simon Goldschmidt <sgoldschmidt@de.pepperl-fuchs.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2018-01-27cmd: nvedit: Get rid of the env lookupMaxime Ripard
The nvedit command is the only user of env_driver_lookup_default outside of the environment code itself, and it uses it only to print the environment it's about to save to during env save. As we're about to rework the environment to be able to handle multiple environment sources, we might not have an idea of what environment backend is going to be used before trying (and possibly failing for some). Therefore, it makes sense to remove that message and move it to the env_save function itself. As a side effect, we also can get rid of the call to env_driver_lookup_default that is also about to get refactored.

The recent changes to these files did not completely fix the previous issues, or introduced different (minor) issues. In cmd/gpt.c we need to dereference str_disk_guid to be sure that malloc worked. In cmd/nvedit.c we need to be careful that we can also fit in that leading space when adding to the string. And in tools/fit_image.c we need to re-work the error handling slightly in fit_import_data() so that we only call munmap() once. We have two error paths here, one where we have an fd to close and one where we do not. Adjust labels to match this.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.
