* base-files: add mtd_get_mac_encrypted_arcadyan functionMikhail Zhilkin2022-08-191-0/+31
| | | | | | | | | Some Arcadyan devices (e.g. MTS WG430223) keep their config in encrypted mtd. This adds mtd_get_mac_encrypted_arcadyan() function to get the MAC address from the encrypted partition. Function uses uencrypt utility for decryption (and openssl if the uencrypt wasn't found).

* failsafe: run on all consoles listed in /proc/cmdlineMark Mentovai2022-06-192-35/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On x86, when both CONFIG_GRUB_CONSOLE and CONFIG_GRUB_SERIAL are set (as they are by default), the kernel command line will have two console= entries, such as console=tty0 console=ttyS0,115200n8 Failsafe was only running a shell on the first defined console, the VGA console. This is a problem for devices like apu2, where there is only a serial console and it appears on ttyS0. Moreover, the console prompt to enter failsafe during boot was delivered to, and its input read from, the last console= on the kernel command line. So while the failsafe shell was on the first defined console, only the last defined console could be used to enter failsafe during boot. In contrast, the x86 bootloader (GRUB) operates on both the serial console and the VGA console by virtue of "terminal_{input,output} console serial". GRUB also provided an alternate means to enter failsafe from either console. The presence of two console= kernel command line parameters causes kernel messages to be delivered to both. Under normal operation (not failsafe), procd runs login in accordance with inittab, which on x86 specifies ttyS0, hvc0, and tty1, allowing login through any of serial, hypervisor, or VGA console. Thus, serial access was consistently available on x86 devices with serial consoles under normal operation, except for shell access in failsafe mode (without editing the kernel command line). By presenting the failsafe prompt, reading failsafe prompt input, and running failsafe shells on all consoles listed in /proc/cmdline, failsafe mode will work correctly on devices with a serial console (like apu2), and the same image without any need for reconfiguration can be shared by devices with the more traditional (for x86) VGA console. This improvement should benefit any system with multiple console= arguments, including x86 and bcm27xx (Raspberry Pi). Signed-off-by: Mark Mentovai <mark at moxienet.com>
* base-files: allow ignoring minor compat-version checkDavid Bauer2022-06-182-0/+5
| | | | | | | | | | | | Downstream projects might re-generate device-specific configuration based on OpenWrt's defaults on each upgrade, thus being unaffected by forward- as well as backwards-breaking configuration. Add a new sysupgrade parameter, which allows sysupgrades between minor compat-versions. Upgrades will still fail upon mismatching major compat versions.

* base-files: fix sysupgrade for kernel-out-of-UBIRodrigo Balerdi2022-05-021-2/+6
| | | | | | | | | | | | | | | | | | | | Commit ecbcc0b59551 bricks devices on which the raw kernel and UBI mtd partitions overlap. This is the case of the ZyXEL NR7101 for example. Its OEM bootloader has no UBI support. OpenWrt splits the stock kernel mtd partition into a raw kernel part used by the bootloader and a UBI part used to store rootfs and rootfs_data. Running mtd erase on the complete partition during sysupgrade erases the UBI part and results in a soft brick. Arguably the best solution would be to fix the partition layouts so that kernel and UBI partitions do not overlap, also including a stock_kernel partition to help reverting to stock firmware. This would have the added benefit of protecting UBI from kernel images that are excessively large.

* ipq40xx: Support Chromium OS image-type creationBrian Norris2022-03-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | See firmware-utils.git commits [1], which implemented the cros-vbutil verified-boot payload-packing tool, and extended ptgen for the CrOS kernel partition type. With these, it's now possible to package kernel + rootfs to make disk images that can boot a Chrome OS-based system (e.g., Chromebooks, or even a few AP models). Regarding PARTUUID= changes: Chromium bootloaders work well with a partition number offset (i.e., relative to the kernel partition), so we'll be using a slightly different root UUID line. NB: I've made this support specific to ip40xx for now, because I only plan to support an IPQ4019-based AP that uses a Chromium-based bootloader, but this image format can be used for essentially any Chromebook, as well as the Google OnHub, a prior Chromium-based AP using an IPQ8064 chipset.

* base-files: call "sync" after initial setupRafał Miłecki2022-03-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenWrt uses a lot of (b)ash scripts for initial setup. This isn't the best solution as they almost never consider syncing files / data. Still this is what we have and we need to try living with it. Without proper syncing OpenWrt can easily get into an inconsistent state on power cut. It's because: 1. Actual (flash) inode and data writes are not synchronized 2. Data writeback can take up to 30 seconds (dirty_expire_centisecs) 3. ubifs adds extra 5 seconds (dirty_writeback_centisecs) "delay" Some possible cases (examples) for new files: 1. Power cut during 5 seconds after write() can result in all data loss 2. Power cut happening between 5 and 35 seconds after write() can result in empty file (inode flushed after 5 seconds, data flush queued) Above affects e.g. uci-defaults. After executing some migration script it may get deleted (whited out) without generated data getting actually written. Power cut will result in missing data and deleted file. There are three ways of dealing with that: 1. Rewriting all user-space init to proper C with syncs 2. Trying bash hacks (like creating tmp files & moving them) 3. Adding sync and hoping for no power cut during critical section This change introduces the last solution that is the simplest. It reduces time during which things may go wrong from ~35 seconds to probably less than a second. Of course it applies only to IO operations performed before /etc/init.d/boot . It's probably the stage when the most new files get created. All later changes are usually done using smarter C apps (e.g. busybox or uci) that creates tmp files and uses rename() that is expected to be atomic.

| | | | | | | | | | | | | | In the default shadow file, as visible in the failsafe mode, the user root has value of `0` set in the 3rd field, the date of last password change. This setting means that the password needs to be changed the next time the user will log in the system. `dropbear` server is ignoring this setting but `openssh-server` tries to enforce it and fails in the failsafe mode because the rootfs is R/O.

* base-files: make sure tools are present in sysupgrade ramdiskDaniel Golle2022-02-221-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all targets create /var/lock or touch /var/lock/fw_printenv.lock in their platform.sh. This is problematic as fw_printenv then fails in case /var/lock/fw_printenv.lock has not been created by previous calls to fw_printenv/fw_setenv before sysupgrade is run. Targets using fw_printenv/fw_setenv during sysupgrade: * ath79/* * ipq40xx/* * ipq806x/* * kirkwood/* * layerscape/* * mediatek/mt7622 * mvebu/* * ramips/* * realtek/* Targets currently using additional steps in /lib/upgrade/platform.sh to make sure /var/lock/fw_printenv.lock (or at least /var/lock) actually exists: * ath79/* (openmesh devices) * ipq40xx/* (linksys devices) * ipq806x/* (linksys devices) * kirkwood/* (linksys devices) * layerscape/* * mvebu/cortexa9 (linksys devices) Given that accessing the U-Boot environment during sysupgrade is not uncommon and the situation across targets is currently quite diverse, just make sure both tools as well fw_env.config are always copied to the ramdisk used for sysupgrade. Also make sure /var/lock always exists. This now allows to remove copying of fw_printenv/fw_setenv as well as fw_env.config, creation of /var/lock or even /var/lock/fw_printenv.lock from lib/upgrade/platform.sh or files included there. As the same applies also to 'fwtool' which is used by generic eMMC sysupgrade, also always copy that to ramdisk. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* base-files: Make sure rootfs_data_max is consideredDaniel Golle2022-02-171-8/+5
| | | | | | | | | | | | | | | For sysupgrade on NAND/UBI devices there is the U-Boot environment variable rootfs_data_max which can be used to limit the size of the rootfs_data volume created on sysupgrade. This stopped working reliable with recent kernels, probably due to a race condition when reading the number of free erase blocks from sysfs just after removing a volume. Change the script to just try creating rootfs_data with the desired size and retry with maximum size in case that fails. Hence calculating the available size in the script can be dropped which works around the problem. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

| | | | | | | | | | | | | | | | | | | | | | | | | Adds generic support for sysupgrading on eMMC-based devices. Provide function emmc_do_upgrade and emmc_copy_config to be used in /lib/upgrade/platform.sh instead of redundantly implementing the same logic over and over again. Similar to generic sysupgrade on NAND, use environment variables CI_KERNPART, CI_ROOTPART and newly introduce CI_DATAPART to indicate GPT partition names to be used. On devices with more than one MMC block device, CI_ROOTDEV can be used to specify the MMC device for partition name lookups. Also allow to select block devices directly using EMMC_KERN_DEV, EMMC_ROOT_DEV and EMMC_DATA_DEV, as using GPT partition names is not always an option (e.g. when forced to use MBR). To easily handle writing kernel and rootfs make use of sysupgrade.tar format convention which is also already used for generic NAND support.

* base-files: dont always create kernel UBI volumeRobert Marko2021-11-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently nand_upgrade_tar() will pass the kernel length to nand_upgrade_prepare_ubi() in all cases except for when the kernel is to be installed in a separate partition as a binary with the MTD tool. While this is fine for almost all cases newer MikroTik NAND devices like hAP ac3 require the kernel to be installed as a UBIFS packed UBI volume in its own partition. So, since we have a custom recipe to use ubiformat to flash the kernel in its partition it makes no sense for sysupgrade to also install the kernel as a UBI volume in the "ubi" partition as it only wastes space and will never be used. So, simply check whether CI_KERNPART is set to "none" and if so unset the "has_kernel" variable which will in turn prevent the kernel length from being passed on and then the kernel UBI volume wont be created for no usefull purpose. The ath79 MikroTik NAND target has been setting CI_KERNPART to "none" for a while now altough that was not preventing the kernel to be installed as UBI volume as well.

Since OpenWrt can run on devices with more durable storage, it makes sense to have an option for a persistent /var. Add an option to make /var persistent. When enabled, /var will no longer be symlinked to /tmp, but /var/run will be symlink to /tmp/run, as it should contains only files that should not be kept during reboot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While an image layout based on MBR and 'bootfs' partition may be easy to understand for users who are very used to the IBM PC and always have the option to access the SD card outside of the device (and hence don't really depend on other recovery methods or dual-boot), in my opinion it's a dead end for many desirable features on embedded systems, especially when managed remotely (and hence without an easy option to access the SD card using another device in case things go wrong, for example). Let me explain: * using a MSDOS/VFAT filesystem to store kernel(s) is problematic, as a single corruption of the bootfs can render the system into a state that it no longer boots at all. This makes dual-boot useless, or at least very tedious to setup with then 2 independent boot partitions to avoid the single point of failure on a "hot" block (the FAT index of the boot partition, written every time a file is changed in bootfs). And well: most targets even store the bootloader environment in a file in that very same FAT filesystem, hence it cannot be used to script a reliable dual-boot method (as loading the environment itself will already fail if the filesystem is corrupted). * loading the kernel uImage from bootfs and using rootfs inside an additional partition means the bootloader can only validate the kernel -- if rootfs is broken or corrupted, this can lead to a reboot loop, which is often a quite costly thing to happen in terms of hardware lifetime. * imitating MBR-boot behavior with a FAT-formatted bootfs partition (like IBM PC in the 80s and 90s) is just one of many choices on embedded targets. There are much better options with modern U-Boot (which is what we use and build from source for all targets booting off SD cards), see examples in mediatek/mt7622 and mediatek/mt7623. Hence rename the 'sdcard' feature to 'legacy-sdcard', and prefix functions with 'legacy_sdcard_' instead of 'sdcard_'.

* base-files: add generic sdcard upgrade methodStijn Tintel2021-08-072-0/+100
| | | | | | | | Add a generic sdcard upgrade method instead of duplicating code in yet another target, and add a feature flag to only install this upgrade method in targets that set this flag. Copied from mvebu. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* base-files: upgrade: try umount lvm and loop devicesDaniel Golle2021-08-041-0/+4
| | | | | | | | Try umount on device mapper and loop devices still mounted, so the subsequent call to disactivate all physical volumes and delete all loop devices is more likely to succeed. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* base-files: sysupgrade stage2: fix losetup detectionDaniel Golle2021-08-031-1/+1
| | | | | | | | | | | | If the busybox applet losetup was selected, `command -v` selects that during sysupgrade. As this applet is in another path and doesn't cover the '-D' option which is used to make sure user-defined loop devices are no longer active during sysupgrade. Detect losetup at the path of the full utility to avoid error messages in case of the busybox applet being selected.
