* kernel: Deactivate CONFIG_SFP in generic configHauke Mehrtens2019-12-231-1/+0
| | | | | | | | Deactivate CONFIG_SFP for kernel 4.19 in the generic configuration. The CONFIG_SFP configuration option was not set to anything in the ath79 build for me, set it to deactivated by default. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* gemini: dir685: Restore graphicsLinus Walleij2019-09-251-0/+1
| | | | | | | | | | | | | | | One of the v4.19 patches had a bug, this is fixed upstream, but in OpenWrt we can fix it by just fixing the bug in the patch. We also need to augment the config file to select the CONFIG_DRM_FBDEV_EMULATION symbol. This restores the display controller on the DIR-685 to working state: penguin and graphics on the little screen with default OpenWrt install. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gemini: Stop enforcing command lineLinus Walleij2019-07-141-2/+0
| | | | | | | | | | | | The command line enforced by the kernel is harmful, we want to use the command line passed from the device tree. This is especially important for the SQ201, Teltonika RUT and WBD111 which has a console set to 115200n8 and not 19200n8 like all the others, so their consoles will be confusingly changing baudrate between boot loader and kernel. The setting in the device tree corresponds to what the boot loader is using. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gemini: enable CONFIG_PACKETChristian Lamparter2019-06-151-1/+0
| | | | | | | | | | CONFIG_PACKET is a important feature to have. The Packet protocol is used by applications which communicate directly with network devices without an intermediate network protocol implemented in the kernel, e.g. tcpdump and ip.

* gemini: Activate Realtek and vitesse DSA driver againHauke Mehrtens2019-05-301-0/+2
| | | | | | | | This activates the wrongly removed DSA drivers again. Fixes 9ab4d74b5f86 ("kernel: Move some DSA config options to generic config") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Reported-by: Linus Walleij <linus.walleij@linaro.org>
* kernel: Move some DSA config options to generic configHauke Mehrtens2019-05-141-4/+0
| | | | | | | This moves some new configuration options to the generic kernel configuration instead of configuring them for each target on our own. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* gemini: Make kernel text and rodata read-onlyHauke Mehrtens2019-05-111-2/+0
| | | | | | | This is activate for all other targets except gemini, also activate it there. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Deactivate CONFIG_BINFMT_MISCHauke Mehrtens2019-05-111-1/+0
| | | | | | | | | | CONFIG_BINFMT_MISC allows it to add support for new executable formats to the kernel from user space, the kernel will then detect for example a java binary and call the java execution program automatically. I am not aware that this feature is used in OpenWrt and this could be used to exploit something. Deactivate it for all targets for now. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Activate CONFIG_SYN_COOKIES for all targetsHauke Mehrtens2019-05-111-1/+0
| | | | | | | | | | Some targets deactivated CONFIG_SYN_COOKIES, for unknown reasons, use the default setting from the generic configuration which activates CONFIG_SYN_COOKIES. This should prevent SYN flooding. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* gemini: Generate padded kernel+rootfs images for DIR-685Linus Walleij2019-03-131-0/+2
| | | | | | | | | | | | | | | | | | | | | We currently generate a kernel that boots from the harddrive in the DIR-685. That's not how we usually do things, so let's augment it to boot from flash and mount the rootfs using squashfs and JFFS2 like everyone else. Partition splitting only work when the partitions are inside of a "partitions" node which is why we have a patch like this (submitted upstream). Another patch drops the rootfs arguments and renames the firmware partition while adding the compatible "wrg" to it so the WRGG parser will kick in. Factory image was tested by bravely reflashing the DIR-685 from stock firmware using the web UI and the serial console boot loader. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gemini: Add a config for kernel v4.19Linus Walleij2019-01-261-0/+495
This adds a config for kernel v4.19 to the Gemini target. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
