* defaultenv: Convert init script to CSascha Hauer2019-04-241-19/+169
| | | | | | | | | | | It's hard to get more complicated things right in hush. This commit converts the /env/bin/init script to C code. With this we get a better error handling and better control what is being done. If /env/bin/init exists in the environment then it is still executed instead of the corresponding C code.

* environment: bypass overlap check for mtd devicesSascha Hauer2018-10-121-0/+3
| | | | | | | | | | | | | | | | For mtd devices the overlap check does not work as expected for two reasons. First is that cdev->offset is 0 for mtd partitions, instead cdev->mtd->master_offset has to be used. That could be fixed easily. Second on NAND devices the environment is on the bb devices and not on the raw nand devices which means we would need something to get the mtd device from the bb device before doing the check. Both issues are fixable, but the check was mainly done to catch cases when an environment partition is created in the free space before the first MBR/GPT partition on SD/MMC devices, so leave out the mtd case for now.

* environment: Do not use environment when overlapping with other partitionsSascha Hauer2018-09-261-1/+51
| | | | | | | | | | | Environment partitions are usually specified with their hardcoded offset and size, either in the device tree or the board file. These partitions potentially overlap with other partitions read from the partition table. Overlapping partitions for sure have bad effects. Be more friendly to our users and warn them when such a situation occurs and stop using that partition for storing the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Revert "startup: Load default environment earlier"Sascha Hauer2018-03-191-3/+3
| | | | | | | | | | | | | | | | Several boards use defaultenv_append_directory() to append a board specific envfs snippet during runtime. This only works when defaultenv_append_directory() is called before defaultenv_load() is exectuted. Since that was executed at the end of the start process every initcall level could be used to append a env directory. With this patch only initcall levels earlier than fsdevice_initcall work and most boards do not cope with this. Revert this patch until a better solution is found. Reported-by: Alexander Kurz <akurz@blala.de> This reverts commit 5b92cfceff38f3a6462a21cf6b69159ad0ae9744.

* | startup: Load default environment earlierSascha Hauer2018-02-061-3/+3
|/ | | | | | | | | | | Some files compiled into the default environment may be needed earlier in the boot process, so move loading of the default environment to fs_initcall. Only the default environment is loaded earlier, but not the overwriting with the persistent environment files, so when the files are used that early, only the compiled in version is available; it's not overwritable at that time.

* fs: Add pstore filesystemMarkus Pargmann2015-12-101-0/+5
| | | | | | | | | | | | | | | | pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a way to extract essential data from the last running kernel. Most of the code is copied from the kernel. However this is only a lightweight implementation without real write support yet. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* login: rework login mechanismSascha Hauer2015-08-281-5/+2
| | | | | | | | | | | | | | We used to have the login functionality in the /env/bin/init script. This is hard to review and it's too easy to break the login functionality with changes to this script. Move the places to ask for a password to C code where we have only a few places where we have to ask for a password. Mainly these are run_shell() and the menutree command. This patch introduces a login() function which will only return if the correct password has been entered. Following calls will return immediately without asking for a password again.

* Add support for non volatile variablesSascha Hauer2014-11-061-0/+2
| | | | | | | | | | | | | | | This adds (back) support for non volatile variables. Non volatile variables are variables which are stored in the environment over reboot. They are used in the same way as the global variables, but with a 'nv' command and device. The variables are stored under /env/nv/, one variable per file. Adding a nv variable automatically adds a global variable with the same name. Changing a nv variable also changes the same global variable, but not the other way round. This allows for example to configure the username as: nv user=sha; saveenv Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | defaultenv: Allow multiple defaultenvironment overlaysSascha Hauer2014-02-281-34/+1
| | | | | | | | | | | | | | | | | | | | We can compile barebox for multiple boards at once, but currently they all share a single default environment. This patch adds a defaultenv_append() which boards can call to customize the default environment during runtime.

* | defaultenv: Align defaultenv arraySascha Hauer2014-02-201-10/+1
| | | | | | | | | | | | | | | | | | | | The default environment buffer is an unsigned char array and thus may be unaligned. Some decompression algorithms expect the buffer to be sufficiently aligned for u32 accesses. We make this sure by copying the default env to a temporary buffer. Instead of doing this just add a __aligned(4) to the default environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | Kconfig: Select default compression typeSascha Hauer2014-02-191-1/+1
|/ | | | | | | | | | Instead of asking explicitly for the default environment compression type ask for the in-barebox default compression type.

* startup: call a barebox_main function pointer at the end of the startupSascha Hauer2013-01-201-1/+12
| | | | | | | | | | | | | | | | | Currently Kconfig dependencies are used to allow non-interactive builds. This leads to problems in Kconfig getting the dependencies right. This patch adds a barebox_main function pointer which is called at the end of the startup process. This defaults to run_shell when a shell is enabled. With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive builds can now be enabled for every board allowing to compile a binary without further Kconfig dependencies. This also allows for more flexibility, for example boards may decide to try non-interactive startup first and call run_shell if that fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | defaultenv: dependencies fixesSascha Hauer2012-10-121-1/+1
|/ | | | | | | | | | | | | | When a build with a compressed default environment is done and then environment compression is disabled, barebox_default_env.h is not regenerated because its dependency (now barebox_default_env) is still up to date. This results in a corrupt default environment. This patch fixes this by adding a cmd_env_h and changing barebox_default_env.h to FORCE. As a side effect barebox_default_env.h is no longer generated in include/generated/ but in common/ as we have to add barebox_default_env.h to $(targets) (extra-y).
