[U-Boot] interaction between CONFIG_CMD_SAVEENV and CONFIG_BOOTCOMMAND
by Nicolas le bayon 15 Sep '16

15 Sep '16

Hi Let me firstly explain my need. We use U-boot as a primary bootloader, with a bootcmd which loads and executes a script on one external device (SD ou USB). This script will continue the boot process (launch a kernel for example). The corresponding bootcmd defined in CONFIG_BOOTCOMMAND does this load/execute operation. Of course, the user will be able to modify the content of the script, to fit with their needs. But on our side, provider of this primary bootloader, we want to be sure that the environment of this u-boot won't be changed by the user, so that we want to disable all access to "saveenv" command. That's why we configure: #undef CONFIG_CMD_SAVEENV With this modifications, saveenv command is not available in the u-boot commands, that's nice. But bootcmd is empty. It's like there was an interaction between both settings, maybe the saveenv primitive is necessary one time to construct the environment content. How could we do to have a well-constructed and not updatable env content? Thanls in advance for your answers Best Regards Nicolas

[U-Boot] [PATCH] ARM: vf610: use strcpy for soc environment variable
by Marcel Ziswiler 15 Sep '16

15 Sep '16

From: Stefan Agner <stefan.agner(a)toradex.com> To create the soc environment variable we concatenate two strings on the stack. So far, strcat has been used for the first string as well as for the second string. Since the variable on the stack is not initialized, the first strcat may not start using the first entry in the character array. This then could lead to an buffer overflow on the stack.

[U-Boot] [PATCH v2 0/2] Detect and reject new ad-hoc CONFIG options
by Simon Glass 14 Sep '16

14 Sep '16

Despite the availability of Kconfig, the number of ad-hoc CONFIG options in U-Boot is still at over 8000. In February 2015 (commit 741e58e0) there were around 8387 ad-hoc CONFIGs. As of this patch there are about 8336, only a little fewer. One problem is that new ones are still being added, admittedly at a slower rate. This series adds a Makefile check to detect that and produce a build error. This provides immediate feedback that new CONFIG options should go in Kconfig. Changes in v2: - Rebase to mainline - Fix scripts so that there are no errors - Add the 'build-whitelist.sh' script to the tree Simon Glass (2): Kconfig: Add a whitelist of ad-hoc CONFIG options Makefile: Give a build error if ad-hoc CONFIG options are added Makefile | 10 +- scripts/build-whitelist.sh | 51 + scripts/check-config.sh | 55 + scripts/config_whitelist.txt | 8419 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 8534 insertions(+), 1 deletion(-) create mode 100755 scripts/build-whitelist.sh create mode 100755 scripts/check-config.sh create mode 100644 scripts/config_whitelist.txt -- 2.8.0.rc3.226.g39d4020
