2021-09-23env: Make _init() expect _INVALID when _IS_NOWHEREPierre-Clément Tosi1-1/+1
Avoid applying the "fix" introduced by commit 5557eec01cbf ("env: Fix invalid env handling in env_init()") to the environment "nowhere". This is necessary as that commit, by setting the return value of env_init() to -ENOENT if gd->env_valid is ENV_INVALID, forces that function to reset gd->env_valid to ENV_VALID. By doing so, it breaks the assumption (required by ENV_IS_NOWHERE) that gd->env_valid must be ENV_INVALID. This, in turn, results in env_relocate() calling env_load() (it should not), which itself, calls U_BOOT_ENV_LOCATION(nowhere).load() i.e. env_nowhere_load(). That function, being implemented under the assumption mentioned above, calls env_set_default(), which in turn, seeing that gd->env_valid is ENV_VALID (it should not), tries to dereference whatever lies in gd->env_addr (most likely garbage), leading to a faulty memory access. Note that other env_locations might be concerned by this bug but that this commit only intends to fix it for when ENV_IS_NOWHERE.

2021-05-04env: allow environment to be amended from control dtbRasmus Villemoes2-0/+48
It can be useful to use the same U-Boot binary for multiple purposes, say the normal one, one for developers that allow breaking into the U-Boot shell, and one for use during bootstrapping which runs a special-purpose bootcmd. Or one can have several board variants that can share almost all boot logic, but just needs a few tweaks in the variables used by the boot script. To that end, allow the control dtb to contain a /config/enviroment node (or whatever one puts in fdt_env_path variable), whose property/value pairs are used to update the run-time environment after it has been loaded from its persistent location. The indirection via fdt_env_path is for maximum flexibility - for example, should the user wish (or board logic dictate) that the values in the DTB should no longer be applied, one simply needs to delete the fdt_env_path variable; that can even be done automatically by including a fdt_env_path = ""; property in the DTB node.

2021-04-16env: sf: add support of command env erasePatrick Delaunay1-0/+34
Add support of opts erase for env in SPI flash; this opts is used by command 'env erase'. This command only fills the env offset by 0x0 (bit flip to 0) and the saved environment becomes invalid (with bad CRC). It doesn't erase the sector here to avoid issue when the sector is larger than the env (i.e. embedded when CONFIG_ENV_SECT_SIZE > CONFIG_ENV_SIZE). The needed sector erase will be managed in the next "env save" command, using the opt ".save", before to update the environment in SPI flash.

2021-04-16env: Fix invalid env handling in env_init()Marek Vasut1-0/+3
This fixes the case where there are multiple environment drivers, one of them is the default environment one, and it is followed by an environment driver which does not implement .init() callback. The default environment driver sets gd->env_valid to ENV_INVALID and returns 0 from its .init() callback implementation, which is valid behavior for default environment. Since the subsequent environment driver does not implement .init(), it also does not modify the $ret variable in the loop. Therefore, the loop is exited with gd->env_valid=ENV_INVALID and ret=0, which means that the code further down in env_init() will not reset the environment to the default one, which is incorrect. This patch sets the $ret variable back to -ENOENT in case the env_valid is set to ENV_INVALID by an environment driver, so that the environment would be correctly reset back to default one, unless a subsequent driver loads a valid environment.

2021-04-16env: Fix warning when forcing environment without ENV_ACCESS_IGNORE_FORCEMartin Fuzzey1-2/+3
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 } Fixes: 0f036bf4b87e ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set") Signed-off-by: Martin Fuzzey <martin.fuzzey@flowbird.group>
2021-04-16env: increment redund flag on read failBrandon Maier2-20/+9
If one of the reads fails when importing redundant environments (a single read failure), the env_flags wouldn't get initialized in env_import_redund(). If a user then calls saveenv, the new environment will have the wrong flags value. So on the next load the new environment will be ignored. While debugging this, I also noticed that env/sf.c was not correctly handling a single read failure, as it would not check the crc before assigning it to gd->env_addr. Having a special error path for when there is a single read failure seems unnecessary and may lead to future bugs. Instead collapse the 'single read failure' error to be the same as a 'single crc failure'. That way env_check_redund() either passes or fails, and if it passes we are guaranteed to have checked the CRC.

2021-04-16env: add CONFIG_ENV_SECT_SIZE_AUTORasmus Villemoes2-2/+22
This is roughly the U-Boot side equivalent to commit e282c422e0 (tools: fw_env: use erasesize from MEMGETINFO ioctl). The motivation is the case where one has a board with several revisions, where the SPI flashes have different erase sizes. In our case, we have an 8K environment, and the flashes have erase sizes of 4K (newer boards) and 64K (older boards). Currently, we must set CONFIG_ENV_SECT_SIZE to 64K to make the code work on the older boards, but for the newer ones, that ends up wasting quite a bit of time reading/erasing/restoring the last 56K. At first, I wanted to allow setting CONFIG_ENV_SECT_SIZE to 0 to mean "use the erase size the chip reports", but that config option is used in a number of preprocessor conditionals, and shared between ENV_IS_IN_FLASH and ENV_IS_IN_SPI_FLASH. So instead, introduce a new boolean config option, which for now can only be used with ENV_IS_IN_SPI_FLASH. If left off, there's no change in behaviour. The only slightly annoying detail is that, when selected, the compiler is apparently not smart enough to see that the the saved_size and saved_offset variables are only used under the same "if (sect_size > CONFIG_ENV_SIZE)" condition as where they are computed, so we need to initialize them to 0 to avoid "may be used uninitialized" warnings. On our newer boards with the 4K erase size, saving the environment now takes 0.080 seconds instead of 0.53 seconds, which directly translates to that much faster boot time since our logic always causes the environment to be written during boot.

2021-01-20env: Remove all dependencies for SYS_REDUNDAND_ENVIRONMENTMichal Simek1-2/+3
CONFIG_SYS_REDUNDAND_ENVIRONMENT is changing in env_internal.h how u-boot works with variables. struct environment_s has one byte flags property which also affects ENV_SIZE macro. I have reached the case where CONFIG_ENV_IS_NOWHERE is default setup but custom scripts can be designed in a way that u-boot is asked to import/export variables from/to file which can be in certain format. That's why also for this configuration make sense to enable CONFIG_SYS_REDUNDAND_ENVIRONMENT because it depends on environment file format. The patch is removing dependency on this configuration to support selecting environment file format without any specific dependency where variables are stored.

Michael wrote: commit 92765f45bb95 ("env: Access Environment in SPI flashes before relocation") at least breaks the Kontron sl28 board. I guess it also breaks others which use a (late) SPI environment. reason is, that env_init() sets the init bit, if there is no init function defined in an environment driver, and use default return value -ENOENT in this case later for setting the default environment. Change: Environment driver can now implement an init function and return, if this function does nothing, simply -ENOENT. env_init() now handles -ENOENT correct by setting the inited bit for the environment driver. And if there is no other environment driver whose init function returns 0, load than the default environment. This prevents that each environment driver needs to set the default environment.
