* state: hmac: fix error message that algo is displayedMarc Kleine-Budde2016-01-181-4/+4
| | | | | | | | | This patch moves the error message about missing crypto support so that the used crypto algo is printed. Without this patch the algo is always shown as a NULL pointer. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | 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>

* | environment: allow saving of symbolic link changesZahari Doychev2015-12-171-9/+10
|/ | | | | | | | | | | | | | | | | | | | Currently it is not possible to change symbolic links in the default environment. For example if the default environment contains the link "current_boot -> mmc" then the following does not work: $ rm current_boot $ ln net current_boot $ saveenv After reset the link is still pointing to "mmc" and this error appears: "symlink: /env/boot/current_boot -> net : error -17" The patch fixes the above problem and moves the "ENV_FLAG_NO_OVERWRITE" to enable handling of symbolic links in this case too.

| * state: backend_raw: add hmac supportMarc Kleine-Budde2015-11-272-8/+137
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds hmac support to the raw backend. With this patch, modifications of the header or data of a state partition can be detected, as the hmac woudln't match anymore. The hmac relies on a shared secret, which is requested from the keystore, with keystore_get_secret() using the name of the state partition as the "name" of the secret.

This behaviour enabled one to mount the FAT FS which is either directly on the device (disk0) or on the first partition (disk0.0) using the same command: mount /dev/disk0 /fat However, the desired behaviour can be reached with a: mount /dev/disk0 /fat || mount /dev/disk0.0 /fat || echo "Mounting failed" Signed-off-by: Peter Mamonov <pmamonov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 104a6a7ccfb7928ca5dc28c8cbe0ea231ffc45ee support was added for Thumb2. It added do_execute() as a way to provide arch dependent calling veneers for use in "go" and thumb2_execute() as the thumb2 to arm veneer. But thumb2_execute() isn't necessary as gcc generates a proper calling sequence from a standard function pointer call. Thumb2 barebox is compiled with the AAPCS ABI which requires this. It also had a bug and didn't pass the arguments properly, but code execute via "go" rarely uses arguments so this wasn't very noticeable. Since thumb2 was always the only user of do_execute(), go ahead and delete that too. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
