* base-files: convert leading spaces to tabs in functions.shAdrian Schmutzler2020-03-131-2/+2

* base-files: Add /etc/shinit for non-login shell initJeffery To2020-03-014-20/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because /etc/profile (and ~/.profile) are read by login shells only, aliases and functions defined there are not available to non-login shells, e.g. when using screen or tmux. If the ENV environment variable exists (exported by /etc/profile or ~/.profile) and references an existing file, then all interactive shells (login or non-login) will read that file as well. This sets the ENV environment variable in /etc/profile, pointing to /etc/shinit. This also adds /etc/shinit, which: * Contains alias and function definitions originally in /etc/profile * Sources /etc/mkshrc if the user is using mksh (also originally in /etc/profile), as /etc/mkshrc is meant for all interactive shells * Sources ~/.mkshrc if the user is using mksh, to compensate for the fact that mksh will not read ~/.mkshrc if ENV is set * Sources ~/.shinit if the user is not using mksh This also removes the shebang from /etc/profile, as the file is sourced, not executed.

* base-files: add all buildinfo with INCLUDE_CONFIGXu Wang2020-02-271-1/+3
| | | | | | | | | | CONFIG_INCLUDE_CONFIG option is helpful for being able to rebuild the exact same firmware as you see on a live OpenWRT instance, but it's crucially missing feeds information, so we can't rebuild the exact same package versions. This commit fixes this by adding the remaining feeds (and version) buildinfo files to the image. Signed-off-by: Xu Wang <xwang1498@gmx.com>
* base-files: diag: restore default trigger for 'boot' LEDPiotr Dymacz2020-02-243-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For devices without a dedicated 'diag' LED, we use sometimes one of other LEDs for indicating at least 'boot', 'failsafe' and 'upgrade' stages. In some cases, at the same time these LEDs have defined default triggers in DTS using 'linux,default-trigger' property. Current 'diag' setup removes the trigger and turns off 'boot' LED after bootup. One of the examples of such device is TP-Link TL-WR841N v14 (ramips) which uses 'wlan' LED with defined 'linux,default-trigger' for 'diag': aliases { led-boot = &led_wlan; led-failsafe = &led_wlan; led-upgrade = &led_wlan; }; [...] led_wlan: wlan { label = "tl-wr841n-v14:green:wlan"; gpios = <&gpio1 9 GPIO_ACTIVE_LOW>; linux,default-trigger = "phy0tpt"; }; This patch extends 'diag.sh' and 'leds.sh' scripts to make sure default trigger defined in DTS is restored for 'diag' LED which isn't used for indicating 'running' stage.

* dropbear: move failsafe code out of base-filesKyle Copperfield2020-01-152-7/+1
| | | | | | | | | | | | The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. Failsafe code of dropbear should be in the dropbear package not the base-files package.

* base-files: send informational UDP message each second waitingPaul Fertser2019-12-191-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The preinit network initialisation and failsafe informational message are inherently racy as the interface takes some time to become functional after "ip link set $pi_ifname up" command. Consider this timing: [ 12.002713] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready [ 12.008819] IPv6: ADDRCONF(NETDEV_UP): eth1.1: link is not ready [ 12.118877] random: procd: uninitialized urandom read (4 bytes read) [ 13.068614] eth1: link up (1000Mbps/Full duplex) [ 13.073309] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready [ 13.080445] IPv6: ADDRCONF(NETDEV_CHANGE): eth1.1: link becomes ready Since the UDP message was sent prior to link becoming ready, it was never seen on the wire. The default failsafe timeout is set to 2 seconds, so with this patch there are two attempts to send the message, one spent in vain, and the other visible in tcpdump on an attached host. Of course, in cases when the interface is brought up faster it leads to two messages, however it should be harmless. This patch (almost) doesn't affect normal boot time while still allowing to enter failsafe reliably with a single button press, matching the official "generic failsafe" documentation.

* base-files: config_generate: split macaddr with multiple ifacesSungbo Eo2019-11-232-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netifd does not handle network.@device[x].name properly if it contains multiple ifaces separated by spaces. Due to this, board.d lan_mac setup does not work if multiple ifaces are set to LAN by ucidef_set_interface_lan. To fix this, create a device node for each member iface when running config_generate instead. Those are named based on the member ifname: ucidef_set_interface_lan "eth0 eth1.1" ucidef_set_interface_macaddr "lan" "yy:yy:yy:yy:yy:01" will return config device 'lan_eth0_dev' option name 'eth0' option macaddr 'yy:yy:yy:yy:yy:01' config device 'lan_eth1_1_dev' option name 'eth1.1' option macaddr 'yy:yy:yy:yy:yy:01' ref: https://github.com/openwrt/openwrt/pull/2542 Signed-off-by: Sungbo Eo <mans0n@gorani.run> [always use new scheme, extend description, change commit title] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* base-files: rename hostname with EUI of mac addressRosy Song2019-11-072-1/+22
| | | | | | | | | | | | | | | If a label MAC address is provided for device, system will rename the hostname with OpenWrt_{eui mac address}. This helps to distinguish between different devices. Since it's no good idea to nest json_* functions, this code does not use get_mac_label directly, but only get_mac_label_dt as external resource.

* base-files: don't store label MAC address in uci system configAdrian Schmutzler2019-11-072-8/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | If set, label MAC address is available from one of two sources, device tree or board.json. So far, the function get_mac_label was meant for retrieving the address, while an option in uci system config was specified only for case 2 (board.json). The uci config option has several drawbacks: - it is only used for a fraction of devices (those not in DT) - label MAC address is a device property, while config implies user interaction - label_macaddr option will only be set if /etc/config/system does not exist (i.e. only for new installations) Thus, this patch changes the behavior of get_mac_label: Instead of writing the value in board.json to uci system config and reading from this location afterwards, get_mac_label now extracts data from board.json directly. The uci config option won't be used anymore. In addition, two utility functions for extraction only from DT or from board.json are introduced. Since this is only changing the access to the label MAC address, it won't interfere with the addresses stored in the code base so far. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* treewide: use a single ath10k MAC patching function with checksumAdrian Schmutzler2019-10-151-7/+1
| | | | | | | | | | | | | | | | While all ath10k eeproms have a checksum field, so far two functions for patching ath10k MAC address have been present (and been used). This merges code to provide a single function ath10k_patch_mac in caldata.sh, having its name in accordance with ath9k functions. By doing so, correct MAC patching for current and future ath10k devices should be ensured. This patch adds checksum adjustments for several targets on ath79 and lantiq.

| | | | | | | | | | | | | | | | | This moves the almost identical calibration data extraction functions present multiple times in several targets to a single library file /lib/functions/caldata.sh. Functions are renamed with more generic names to merge different variants that only differ in their names. Most of the targets used find_mtd_chardev, while some used find_mtd_part inside the extraction code. To merge them, the more abundant version with find_mtd_chardev is used in the common code.

* base-files: coreutil-date breaks setting kernel timezoneVal Kulkov2019-10-121-1/+1
| | | | | | | | | | | | | | | | "coreutil-date" package from the packages feed replaces the Busybox date applet by symlinking /usr/bin/gnu-date to /bin/date. This prevents the system init script from setting kernel timezone because the GNU date utility does not provide such functionality: root@OpenWrt:~# date -k date: invalid option -- 'k' Try 'date --help' for more information.

* base-files: provide option to specify label MAC address in board.dAdrian Schmutzler2019-09-193-0/+14
| | | | | | | | | | | | | | For many devices, MAC addresses cannot be retrieved via the device tree alias. To still provide the label MAC address for those, this implements a second mechanism that will put the address into uci config. Note that this stores the actual MAC address, whereas in DTS we reference the bearing device.

* base-files: use JSON for storing firmware validation infoRafał Miłecki2019-08-302-14/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far firmware validation result was binary limited: it was either successful or not. That meant various limitations, e.g.: 1) Lack of proper feedback on validation problems 2) No way of marking firmware as totally broken (impossible to install) This change introduces JSON for storing detailed validation info. It provides a list of performed validation tests and their results. It allows marking firmware as non-forceable (broken image that can't be even forced to install). Example: { "tests": { "fwtool_signature": true, "fwtool_device_match": true }, "valid": true, "forceable": true } Implementation is based on *internal* check_image bash script that: 1) Uses existing validation functions 2) Provides helpers for setting extra validation info This allows e.g. platform_check_image() to call notify_check_broken() when needed & prevent user from bricking a device. Right now the new JSON info is used by /sbin/sysupgrade only. It still doesn't make use of "forceable" as that is planned for later development. Further plans for this feature are: 1) Expose firmware validation using some new ubus method 2) Move validation step from /sbin/sysupgrade into "sysupgrade" ubus method so: a) It's possible to safely sysupgrade using ubus only b) /sbin/sysupgrade can be more like just a CLI Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
