env: Fix network support when CONFIG_NET_LWIP is set

2025-05-30T19:43:24+00:00

When lwIP (CONFIG_NET_LWIP) is used instead of legacy stack (CONFIG_NET),
environment flags support associated with network was not built: restore
support of "i" and "m" environment flags.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

env: Couple networking-related variable flags to CONFIG_NET

2023-02-10T16:24:08+00:00

Boards may set networking variables programmatically, thus may have
CONFIG_NET on but CONFIG_CMD_NET off. The IOT2050 is an example.

env: Fix warning when forcing environment without ENV_ACCESS_IGNORE_FORCE

2021-04-16T15:55:55+00:00

Since commit 0f036bf4b87e ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set")
a warning message is displayed when setenv -f is used WITHOUT
CONFIG_ENV_ACCESS_IGNORE_FORCE, but the variable is set anyway, resulting
in lots of log pollution.

env_flags_validate() returns 0 if the access is accepted, or non zero
if it is refused.

So the original code
	#ifndef CONFIG_ENV_ACCESS_IGNORE_FORCE
		if (flag & H_FORCE)
			return 0;
	#endif

was correct, it returns 0 (accepts the modification) if forced UNLESS
IGNORE_FORCE is set (in which case access checks in the following code
are applied). The broken patch just added a printf to the force accepted
case.

To obtain the intent of the patch we need this:
	if (flag & H_FORCE) {
	#ifdef CONFIG_ENV_ACCESS_IGNORE_FORCE
		printf("## Error: Can't force access to \"%s\"\n", name);
	#else
		return 0;
	#endif
	}

env: Add support for explicit write access list

2020-07-31T14:13:00+00:00

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.

If the ENV_ACCESS_IGNORE_FORCE is set, inform user that the variable
cannot be force-set if such attempt happens.

make env_entry::callback conditional on !CONFIG_SPL_BUILD

2020-04-24T14:09:59+00:00

The callback member of struct env_entry is always NULL for an SPL
build. Removing it thus saves a bit of run-time memory in the
SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded
in struct env_entry_node - i.e. about 2KB for the normal case of
512+change hash table entries.

Two small fixups are needed for this, all other references to the
callback member are already under !CONFIG_SPL_BUILD: Don't initialize
.callback in set_flags() - hsearch_r doesn't use that value
anyway. And make env_callback_init() initialize ->callback to NULL for
a new entry instead of relying on an unused or deleted entry having
NULL in ->callback.

env: Rename environment.h to env_internal.h

2019-08-11T23:27:31+00:00

This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.

Rename this file and add a comment at the top to indicate its internal
nature.
