lib/hashtable.c: use memdup_nul() in himport_r

2026-05-12T21:38:00Z

We have memdup_nul() for exactly this pattern of duplicating a block of memory and ensuring there's a nul byte after the copy. Reviewed-by: Simon Glass Signed-off-by: Rasmus Villemoes

lib: hashtable: Prevent recursive calling of callback functions

2024-12-07T12:07:45Z

In case there are two variables which each implement env callback that performs env_set() on the other variable, the callbacks will call each other recursively until the stack runs out. Prevent such a recursion from happening. Example which triggers this behavior: static int on_foo(...) { env_set("bar", 0); ... } static int on_bar(...) { env_set("foo", 0); ... } U_BOOT_ENV_CALLBACK(foo, on_foo); U_BOOT_ENV_CALLBACK(bar, on_bar); Signed-off-by: Christoph Niedermaier Suggested-by: Marek Vasut

global: Use CONFIG_XPL_BUILD instead of CONFIG_SPL_BUILD

Complete this rename for all directories outside arch/ board/ drivers/ and include/ Use the new symbol to refer to any 'SPL' build, including TPL and VPL Signed-off-by: Simon Glass

lib: Remove duplicate newlines

Drop all duplicate newlines. No functional change. Signed-off-by: Marek Vasut

lib: Remove inclusion from these files

2023-12-21T13:54:37Z

After some header file cleanups to add missing include files, remove common.h from all files in the lib directory. This primarily means just dropping the line but in a few cases we need to add in other header files now. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

Correct SPL use of ENV_WRITEABLE_LIST

2023-02-09T21:32:26Z

This converts 1 usage of this option to the non-SPL form, since there is no SPL_ENV_WRITEABLE_LIST defined in Kconfig Signed-off-by: Simon Glass

Convert CONFIG_ENV_MIN_ENTRIES et al to Kconfig

env: Allow returning errors from hdelete_r()

2020-12-04T21:09:06Z

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 wip

lib/hashtable: remove superfluous check

We assign first_deleted = 0. There is no need to check its value without any further assignment in between. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

env: Add support for explicit write access list

2020-07-31T14:13:00Z

This option marks any U-Boot variable which does not have explicit 'w' writeable flag set as read-only. This way the environment can be locked down and only variables explicitly configured to be writeable can ever be changed by either 'env import', 'env set' or loading user environment from environment storage.
