2025-12-18cmd: nvedit: Validate argument count before useMarek Vasut
Avoid NULL pointer dereference in case 'env select' is invoked without parameters, check the arg count and make sure it is at least 2, otherwise print usage.

2025-05-11cmd: nvedit: fix efi env -e -i command helpVincent Stehlé
The help string for the `setenv -e' command shows a comma being used as the separator between address and size for the -i option, which deals with UEFI Variables contents passed as a buffer in memory. This is no longer the case since commit 2b3fbcb59f41 ("efi_loader: use ':' as separator for setenv -i") and commit 8f0ac536d493 ("efi: change 'env -e -i' usage syntax"), which changed the separator from a comma to a colon. Therefore fix this last bit of the help string accordingly. While at it, fix the comment of function do_env_set_efi(), which also mentions a comma as separator.

2024-11-15cmd/nvedit.c: teach 'env default' to optionally keep runtime variablesRasmus Villemoes
It can be useful to set all variables defined in the default environment to the value they have there, but without removing variables that are only defined at runtime. This can sort-of be done today, by using the "env default var1 var2 ..." variant, but that requires listing all variables defined in the default environment. It's much more convenient to be able to say env default -k -a The -k flag is also meaningful in the other case: If var1 is not defined in the default environment, but var2 is, env default var1 var2 would emit a warning about var1 not being in the default env and thus being deleted. With -k, there's no warning, and var1 is kept as-is. Signed-off-by: Rasmus Villemoes <[email protected]>

2023-11-07env: Move env_set() out of cmd/nvedit.c and in to env/common.cTom Rini
Inside of env/common.c we already have our helper env_set_xxx functions, and even have a comment that explains why env_set() itself wasn't moved. We now handle that move. This requires that we rename the previous _do_env_set() to env_do_env_set() and note it as an internal env function. Add comments about this function to explain why we do this when we add the prototype. Add a new function, env_inc_id() to allow for the counter to be updated by both commands and callers, and document this as well by the prototype. Signed-off-by: Tom Rini <[email protected]>

2021-10-21env: Simplify env_match() and inline into env_get_f()Marek Behún
In the past the env_match() function was used to match envs with - name, i.e. string "name" - variable assignment, i.e. string "name=other_value" The latter is not the case anymore, since the env_match() function is now used only in env_get_f(), and so we can simplify the function into a simple strncmp() with an additional comparison to '='. Let's do this, and since the resulting function is quite simple, let's also inline its code into env_get_f().

2021-10-21env: Make return value of env_get_f() behave like sprintf() on successMarek Behún
Currently the env_get_f() function's return value behaves weirdly: it returns the number of bytes written into `buf`, but whether this is excluding the terminating NULL-byte or including it depends on whether there was enough space in `buf`. Change the function to always return the actual length of the value of the environment variable (excluding the terminating NULL-byte) on success. This makes it behave like sprintf().

2021-10-21env: Use string pointer instead of indexes in env_get_f()Marek Behún

2021-10-21env: Inline env_get_char() into its only userMarek Behún
This function is a relic from the past when environment was read from underlying device one character at a time. It is used only in the case when getting an environemnt variable prior relocation, and the function is simple enough to be inlined there. Since env_get_char() is being changed to simple access to an array, we can drop the failing cases and simplify the code (this could have been done before, since env_get_char() did not fail even before).

2020-12-04env: Allow returning errors from hdelete_r()Simon Glass
At present this function returns 1 on success and 0 on failure. But in the latter case it provides no indication of what went wrong. If an attempt is made to delete a non-existent variable, the caller may want to ignore this error. This happens when setting a non-existent variable to "", for example. Update the function to return 0 on success and a useful error code on failure. Add a function comment too. Make sure that env_set() does not return an error if it is deleting a variable that doesn't exist. We could update env_set() to return useful error numbers also, but that is beyond the scope of this change. Signed-off-by: Simon Glass <[email protected]> wip
