* umdns: add missing syscalls to seccomp filterDaniel Golle2021-04-101-27/+30
| | | | | | | | | | | | | | | Looks like 'openat', 'pipe2' and 'ppoll' are now needed, possibly due to changes on libraries used by umdns now using slightly different calls. Found using /etc/init.d/umdns trace now use umdns, ie. cover all ubus call etc., then /etc/init.d/umdns stop find list of syscalls traced in /tmp/umdns.*.json Fixes: FS#3355 ("UMDNS: does not start on master with seccomp") Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* uboot-mediatek: add build for Ubiquiti Networks UniFi 6 LRDaniel Golle2021-04-094-7/+485
| | | | | | | | | | | | | | | | Add U-Boot build for the Ubiquiti Networks UniFi 6 LR access point. This allows updating the bootchain to modern ARM Trusted Firmware 2.4 and U-Boot 2021.04 while keeping as much of the existing flash layout as possible (u-boot-env, factory and eeprom partitions are retained), gaining robust recovery vs. production dual-boot mechanism. Add info for the Winbond W25Q512JV SPI NOR flash used in the device and wait for GPIOs to settle after reset before checking for reset button. I2C connected LED controller is not supported yet. Writing large amounts of data to SPI flash currently doesn't work due to watchdog timeout causing reset before data write completes. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* kernel: support FIT partition parser on mtdblock devicesDaniel Golle2021-04-094-12/+241
| | | | | | | | | | | | | | | Allow using the FIT block-device partition partition parser to work on top of mtdblock devices. This is more tricky than it sounds as it requires to reorganize the procedure of registering mtdblock devices in order to avoid locking troubles caused by the block partition parsers then trying to open the mtdblock device for reading while locks are still being held. Fix that by moving the adding of the disks after the entire device has been probed when locks no longer need to be held. Also address issue with mtdsuper surfaced when using sub-partitions which prevented mounting JFFS2 using the /dev/mtdblock* device. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* kernel: mtdsplit_fit: support FIT with external dataDaniel Golle2021-04-091-39/+243
| | | | | | | | | | | | | | | | | | U-Boot has recently added support for having data blobs in uImage.FIT images stored at offsets after the FDT structure rather than embedding the data into the FDT structure itself. This is useful as it allows parts of the image to be mapped by the FIT partition parser, and it allows the FIT structure itself to be parsed more easily as it usually fits into single page. mtdsplit_fit assumed that the total length of an image is identical to the length of the FDT structure. For uImage.FIT with external data this assumption no longer holds true. Add support for uImage.FIT with external data to mtdsplit_fit and in in that case only split-off rootfs_data -- selecting and mapping rootfs partition is left to the block partition parser just like on UBI and block/GPT based platforms.

* bcm4908: enable Netgear R8000P bootloader imageRafał Miłecki2021-04-081-2/+2
| | | | | | | | | | | | | | | | | | This enables building BCM4908 "raw" image that can be flashed using bootloader web UI. It requires serial console access & stopping booting by the "Press any key to stop auto run". It's easy to build vendor like CHK image but it can't be safely flashed using vendor UI at this point. Netgear implements method called "NAND incremental flashing" that doesn't seem to flash bootfs partition as provided. Above method seems to update vmlinux.lz without updating 94908.dtb. It prevents OpenWrt kernel from booting due to incomplete DTB file. Full Netgear R8000P support can be enabled after finding a way to make vendor firmware flash OpenWrt firmware including the 94908.dtb update. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* ath79: add Senao 'failsafe' sysupgrade procedureMichael Pratt2021-04-089-4/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a similar upgrade method for sysupgrade.bin, like factory.bin, for Senao boards with the tar.gz OEM upgrade platform, and 'failsafe' image which is loaded on checksum failure. This is inspired by the OEM upgrade script /etc/fwupgrade.sh and the existing platforms for dual-boot Senao boards. Previously, if the real kernel was damaged or missing the only way to recover was with UART serial console, because the OKLI lzma-loader is programmed to halt. uboot did not detect cases where kernel or rootfs is damaged and boots OKLI instead of the failsafe image, because the checksums stored in uboot environment did not include the real kernel and rootfs space. Now, the stored checksums include the space for both the lzma-loader, kernel, and rootfs. Therefore, these boards are now practically unbrickable. Also, the factory.bin and sysupgrade.bin are now the same, except for image metadata. This allows for flashing OEM image directly from openwrt as well as flashing openwrt image directly from OEM. Make 'loader' partition writable so that it can be updated during a sysupgrade. tested with ENS202EXT v1 EAP1200H EAP350 v1 EAP600 ECB350 v1 ECB600 ENH202 v1 Signed-off-by: Michael Pratt <mcpratt@pm.me>
* ath79: adjust ath79/tiny Senao APs to 4k blocksizeMichael Pratt2021-04-086-3/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath79/tiny kernel config has CONFIG_MTD_SPI_NOR_USE_4K_SECTORS=y from commit 05d35403b211ccb9bf20e2b3c0b7a30c82c6d6a2 Because of this, these changes are required for 2 reasons: 1. Senao devices in ath79/tiny with a 'failsafe' partition and the tar.gz sysupgrade platform and a flash chip that supports 4k sectors will fail to reboot to openwrt after a sysupgrade. the stored checksum is made with the 64k blocksize length of the image to be flashed, and the actual checksum changes after flashing due to JFFS2 space being formatted within the length of the rootfs from the image example: 0x440000 length of kernel + rootfs (from sysupgrade.bin) 0x439000 offset of rootfs_data (from kernel log) 2. for boards with flash chips that support 4k sectors: saving configuration over sysupgrade is not possible because sysupgrade.tgz is appended at a 64k boundary and the mtd parser starts JFFS2 at a 4k boundary. for boards with flash chips that do not support 4k sectors: partitioning with 4k boundaries causes a boot loop from the mtd parser not finding kernel and rootfs. Also: Some of the Senao boards that belong in ath79/tiny, for example ENH202, have a flash chip that does not support 4k sectors (no SECT_4K symbol in upstream source). Because of this, partitioning must be different for these devices depending on the flash chip model detected by the kernel. Therefore: this creates 2 DTSI files to replace the single one with 64k partitioning for 4k and 64k partitioning respectively. Signed-off-by: Michael Pratt <mcpratt@pm.me>
* ath79: remove 'fakeroot' for Senao devicesMichael Pratt2021-04-086-49/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By using the same custom kernel header magic in both OKLI lzma-loader, DTS, and makefile this hack is not necessary anymore However, "rootfs" size and checksum must now be supplied by the factory.bin image through a script that is accepted by the OEM upgrade script. This is because Senao OEM scripts assume a squashfs header exists at the offset for the original "rootfs" partition which is actually the kernel + rootfs in this implementation, and takes size value from the header that would be there with hexdump, but this offset is now the uImage header instead. This frees up 1 eraseblock previously used by the "fakeroot" partition for bypassing the OEM image verification. Also, these Senao devices with a 'failsafe' partition and the tar-gz factory.bin platform would otherwise require flashing the new tar-gz sysupgrade.bin afterward. So this also prevents having to flash both images when starting from OEM or 'failsafe' the OEM upgrade script verifies the header magic numbers, but only the first two bytes. Example: [ "${magic_word_kernel}" = "2705" ] && [ "${magic_word_rootfs}" = "7371" -o "${magic_word_rootfs}" = "6873" ] && errcode="0" therefore picked the magic number 0x73714f4b which is 'sqOK' Signed-off-by: Michael Pratt <mcpratt@pm.me>
* ath79: lzma-loader: allow setting custom kernel magicMichael Pratt2021-04-084-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ...and max flash offset The mtdsplit parser was recently refactored to allow the kernel to have custom image header magic. Let's also do this for the lzma-loader For example: When implemented together, this allows the kernel to "appear" to be a rootfs by OEM software in order to write an image that is actually kernel + rootfs. At the same time, it would boot to openwrt normally by setting the same magic in DTS. Both of the variables have a default value that is unchanged when not defined in the makefiles This has no effect on the size of the loader when lzma compressed.
