* base-files: remove unused vn and _vn functionFlorian Eckert2021-06-201-8/+0
| | | | | | | The remaining vn calls have been ported to v. Therefore, these functions are no longer needed and will be removed. Signed-off-by: Florian Eckert <fe@dev.tdt.de>

* base-files: add syslog logging for v functionFlorian Eckert2021-06-202-1/+2
| | | | | | | | The logging output should not only be displayed in the calling shell session but also in the syslog. A sysupgrade and a configuration import, export can thus be traced in the syslog. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
* base-files: upgrade: use zcat command provided by busyboxChuck Fan2021-06-201-1/+1
| | | | | | | | | | | Calling `switch_to_ramfs()` will not copy the gzip executable (/bin/gzip) to ramfs, but `/bin/zcat` will call `/bin/gzip` when package gzip is installed, instead of the busybox-supplied zcat. This will cause `zcat` to fail to find `gzip`, then cause the sysupgrade to fail. Adding the `busybox` prefix here will solve the problem. Signed-off-by: Chuck Fan <fanck0605@qq.com>

* base-files: upgrade: use procd to kill managed daemonsMichael Pratt2021-06-121-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These processes are managed by procd and set to start again when killed via the procd instance parameter "respawn" being set during init. Example: procd_set_param respawn 3600 1 0 When they are killed manually during sysupgrade, they are started again in 5 seconds or less, depending on how the "respawn" parameter is set. Use procd through ubus to disable the instances that respawn them, however, allow dnsmasq, netifd, and logd to restart for remote logging. Properly closing all these processes increases free memory by about 3 MB, which should help low memory devices upgrade without crashing. For very low memory devices (set to 32 MB for now) also kill dnsmasq, netifd, and logd for an additional 3 MB of free memory. Also, bump sleep values to allow at least 10 seconds for network interfaces and daemons to come up after they are killed and restarted before caches are dropped.

* base-files: upgrade: take down loop and LVM before upgradeDaniel Golle2021-05-051-0/+10
| | | | | | | | | | | | | | Users of devices with large block storage may choose to have an LVM partition on the same device which is used for booting OpenWrt. The presents a problem during sysupgrade as the root device is then still busy and changing partitions will not work as desired, leading to data corruption in case the newly flashed image is larger than the currently installed one. Having loop devices setup causes similar havoc. Make sure all volume groups are offline and all loop devices have been released before sysupgrade. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* sysupgrade-nand: allow limiting rootfs_data by setting env variableDaniel Golle2021-02-241-4/+16
| | | | | | | | | | | | | | | | | Check if firmware environment variable 'rootfs_data_max' exists and is set to a numerical value greater than 0. If so, limit rootfs_data volume to that size instead of using the maximum available size. This is useful on devices with lots of flash where users may want to have eg. a volume for persistent logs and statistics or for external applications/containers. Persistence on rootfs overlay is limited by the size of memory available during the sysugprade process as that data needs to be copied to RAM while the volume is being recreated during sysupgrade. Hence it is unsuitable for keeping larger amounts of data accross upgrade which makes additional volume(s) for application data desirable. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* image: add support for building FIT image with filesystemDaniel Golle2021-02-241-37/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow for single (external-data) FIT image to hold kernel, dtb and squashfs. In that way, the bootloader verifies the system integrity including the rootfs, because what's the point of checking that the hash of the kernel is correct if it won't boot in case of squashfs being corrupted? Better allow bootloader to check everything needed to make it at least up to failsafe mode. As a positive side effect this change also makes the sysupgrade process on nand potentially much easier as it is now. In short: mkimage has a parameter '-E' which allows generating FIT images with 'external' data rather than embedding the data into the device-tree blob itself. In this way, the FIT structure itself remains small and can be parsed easily (rather than having to page around megabytes of image content). This patch makes use of that and adds support for adding sub-images of type 'filesystem' which are used to store the squashfs. Now U-Boot can verify the whole OS and the new partition parsers added in the Linux kernel can detect the filesystem sub-images, create partitions for them, and select the active rootfs volume based on the configuration in FIT (passing configuration via device tree could be implemented easily at a later stage). This new FIT partition parser works for NOR flash (on top of mtdblock), NAND flash (on top of ubiblock) as well as classic block devices (ie. eMMC, SDcard, SATA, NVME, ...). It could even be used to mount such FIT images via `losetup -P` on a user PC if this patch gets included in Linux upstream one day ;) Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* base-files: allow exceptions when removing devicename from LEDsAdrian Schmutzler2020-10-021-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Without the model-based devicename for LEDs, there are still cases where a third component is required, typically when it refers to internal "devices" like phys etc. An example are the following two found on ramips: - rt2800soc-phy0::radio - rt2800pci-phy0::radio So far, the rt2800*-phy: prefixes would be removed by the devicename removal ("migration") script, and the configuration for these LEDs would be broken. To address this, this patch allows to add arguments to a call of remove_devicename_leds, which will be compared against the first part of the LED names/labels, and then be ignored by the routine, and thus not removed: remove_devicename_leds "rt2800soc-phy0" "rt2800pci-phy0" This mechanism is supposed to be used when a "devicename" applies to several devices. If only a single device is affected, it might be more effective to use a case statement and exclude the device from migration by that entirely.

* base-files: add function to remove devicename from LED labelsAdrian Schmutzler2020-10-021-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we request LED labels in OpenWrt to follow the scheme modelname:color:function However, specifying the modelname at the beginning is actually entirely useless for the devices we support in OpenWrt. In patches subsequent to this one, we will thus remove the modelname from the label definitions on various targets. To migrate the existing definitions from older installations, a migration script needs to be deployed that does modelname:color:function -> color:function e.g. dir-789:green:status -> green:status This patch introduces two functions that do exactly that: For each entry in /etc/config/system, the routine will check whether two (or more) colons are present, and then remove everything up to (and including) the first colon. For now, this will be applied unconditionally, i.e. if the function is called for a device, all labels will be cut like this. However, for a future case of mixed three-part and two-part labels, it should not be too hard to provide a function argument with exceptions to the removal.

When the passed section or option name contains other characters which are not valid within a shell variable name, a substitution error is occuring instead. The issue can be easily reproduced by one of the following examples: root@OpenWrt:~# . /lib/functions.sh root@OpenWrt:~# config load system root@OpenWrt:~# config_get variable invalid-section option root@OpenWrt:~# echo "$variable" section_option:- root@OpenWrt:~# . /lib/functions.sh root@OpenWrt:~# config load system root@OpenWrt:~# config_get variable section invalid-option root@OpenWrt:~# echo "$variable" option:- root@OpenWrt:~# . /lib/functions.sh root@OpenWrt:~# config load system root@OpenWrt:~# config_get variable section invalid@option -ash: eval: syntax error: bad substitution Fix this issue by only performing interpolations when the given section and option arguments are free of illegal characters.

* base-files: fwtool: make compat_version backward compatibleAdrian Schmutzler2020-07-311-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, the compatibility mechanism only works if both device and image are already updated to the new routines. This patch extends the sysupgrade metadata and fwtool_check_image() to account for "older" images as well: The basic mechanism for older devices to check for image compatibility is the supported_devices entry. This can be exploited by putting a custom message into this variable of the metadata, so older FW will produce a mismatch and print the message as it thinks it's the list of supported devices. So, we have two cases: device 1.0, image 1.0: The metadata will just contain supported_devices as before. device 1.0, image 1.1: The metadata will contain: "new_supported_devices":["device_string1", "device_string2", ...], "supported_devices":["Image version 1.1 incompatible to device: ..."] If the device is "legacy", i.e. does not have the updated fwtool.sh, it will just fail with image check and print the content of supported_devices. If DEVICE_COMPAT_MESSAGE is set, this will be printed on old devices as well through the same mechanism. Otherwise a generic "Please check documentation ..." is appended. Upgrade can still be performed with -F like when SUPPORTED_DEVICES has been removed to prevent bricking. If the device has updated fwtool.sh (but is 1.0), it will just use the new_supported_devices instead, and work as intended (flashing with -n will work, flashing without will print the appropriate warning). This mechanism should provide a fair tradeoff between simplicity and functionality. Since we touched a lot of fields in metadata, this also bumps metadata_version to 1.1.

* base-files: fwtool: implement compatibility check for imagesAdrian Schmutzler2020-07-311-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We regularly encounter the situation that devices are subject to changes that will make them incompatible to previous versions. Removing SUPPORTED_DEVICES will not really be helpful in most of these cases, as this only helps after a rename. To solve this situation, this patchset introduces a compatibility version for devices. In this patch, the actual checks are implemented into fwtool_check_image(): If an incompatible change is introduced, one can increase either the minor version (1.0->1.1) or the major version (1.0->2.0). Minor version increment: This will still allow sysupgrade, but require to reset config (-n or SAVE_CONFIG=0). If sysupgrade is called without -n, a corresponding message will be printed. If sysupgrade is called with -n, it will just pass, with supported devices being checked as usual. (Which will allow us to add back SUPPORTED_DEVICES for many cases.) Major version increment: This is meant for potential (rare) cases where sysupgrade is not possible at all, because it would break the device. In this case, a warning will be printed, and -n won't help. If image check fails because of one of the versions parts not matching, the content of DEVICE_COMPAT_MESSAGE is printed in addition to the generic message (if set). For both cases, upgrade can still be forced with -F as usual. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* base-files: add support for compat_version on deviceAdrian Schmutzler2020-07-311-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We regularly encounter the situation that devices are subject to changes that will make them incompatible to previous versions. Removing SUPPORTED_DEVICES will not really be helpful in most of these cases, as this only helps after a rename. To solve this situation, this patchset introduces a compatibility version for devices. To complement the DEVICE_COMPAT_VERSION set for the image to be flashed, this implements a compat_version on the device, so it will have something to compare with the image. The only viable way to achieve this seems to be via board.d files, i.e. this is technically adding a compat version for the device's config. Like for the network setup, this will set up a command ucidef_set_compat_version to set the compat_version in board.d. This will then add a string to /etc/board.json, which will be translated into uci system config by bin/config_generate. By this, the compat_version, being a version of the config, will also be exposed to the user. As with DEVICE_COMPAT_VERSION, missing uci entry will be assumed as compat_version "1.0", so we only need to add this if a device needs to be bumped, e.g. ucidef_set_compat_version "1.1" Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* base-files: gpio switch: add named GPIO supportKuan-Yi Li2020-06-181-1/+1
| | | | | | | | | | | | | | | | Previously, gpio_switch only accepts GPIO pin number as input. Once a GPIO pin is exported and named by device tree, its pin state cannot be configured and saved across reboots by UCI. This patch adds support for named GPIO pins. Thus GPIO pin can be exported by device tree with active high/low correctly configured, having human-readable name in /sys/class/gpio/ is also now possible. More importantly, GPIO pins which are referenced by name will be immune from pin mapping breakage while unintentional pin number changes are introduced by kernel or driver updates.
