* base-files: add 'isup' to the wifi scriptAndre Heider2023-04-121-1/+18
| | | | | | | | | | | | | | This is a silent command that allows easy wifi up/down automation for scripts. It takes one or multiple devices as arguments (or all if none are passed), and the exit code indicates if any of those is not up. E.g.: wifi isup && echo "all wifi devices are up" wifi isup radio0 || echo "this wifi is down" Signed-off-by: Andre Heider <a.heider@gmail.com>

* base-files: fix nand_upgrade_ubinized()Rafał Miłecki2023-04-111-1/+3
| | | | | | | | | | | | | | | | | | When using "ubiformat" with stdin it requires passing image size using the -S argument. Provide it just like we do for "ubiupdatevol". This fixes: ubiformat: error!: must use '-S' with non-zero value when reading from stdin This change fixes sysupgrade for bcm53xx and bcm4908 NAND devices possibly some other targets too.

* base-files: sysfixtime: Fix time on the fake RTCYuan Tao2023-02-191-6/+16
| | | | | | | | | | | | | | | On some devices the chip has RTC but no battery save time. This leads back to getting the wrong time and skipping the check of the last file modification date. This commit ensures that the file time is checked even if the RTC exists. which would ordinarily return an approbiate system time used for e.g. certificate generation.

| | | | | | | | | | | We currently have build options to customize the IP address used in the preinit phase of the boot process, but not to set the default LAN IP. Introduce a boolean build option that, when enabled, results in the IP address configured for the preinit phase, to be also used as the default LAN IP address.

* ramips: add basic support for tp-link er605-v2Nikolay Martynov2023-01-041-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a MT7621-based device with 128MB NAND flash, 256MB RAM, and a USB port. The board has headers to attach console. In order for them to work two solder bridges near those pads need to be made. The defice has the following partition table: ``` 0x000000000000-0x000000080000 : "u-boot" 0x000000080000-0x000000100000 : "u-boot-env" 0x000000100000-0x000000140000 : "factory" 0x000000140000-0x000007e00000 : "firmware" 0x000007e00000-0x000008000000 : "panic-ops" ``` `firmware` partition contains UBI volumes. Unfortunately I accidentally wiped partition and I no longer have access to it. `firmware` partition contains 'secondary' U-Boot which is run by 'first' u-boot. It also contains various configuration partitions that include device info and MAC address. There also seems to be 'primary' and 'backup' set of 'main' volumes. U-boot has `mtkupgrade` command that just overrides data on firmware partitions. Firmware file provided by TP-Link cannot be used with that command. U-boot also has 'recovery' http server. Unfortunately I was not able to make it work with manufacturer's firmware. Manufacturer's firmware essentially contains multiple UBI volumes along with 'partition table'. Unfortunately I no longer can properly run manufacturer's firmware so I cannot at the moment try to a support for building 'factory' images. This patch adds support for initramfs image as well as sysupgrade image. This seems to be pretty standard MT7621 board otherwise.

* base-files: accept gzipped nand sysupgrade imagesRodrigo Balerdi2022-10-301-31/+55
| | | | | | | | | | | | | | | | When firmware images only contained compressed kernels and squashfs roots, uncompressed tar files were a good option. We are now using UBIFS images, both raw and tarred, as well as ubinized (full UBI partition) images, all of which benefit greatly from compression. For example, a raw ubinized backup taken from a running Askey RT4230W REV6 (such full backups can be restored via the LUCI's sysupgrade UI) is over 400 MB, but compresses to less than 10 MB. This commit adds support for gzipped versions of all file types already accepted by the nand sysupgrade mechanism, be them raw or tarred. Signed-off-by: Rodrigo Balerdi <lanchon@gmail.com>

* base-files: rename ethernet devs on known boardsMartin Kennedy2022-09-102-0/+51
| | | | | | | | | | | | | | | | Some platforms lack an established way to name netdevs; for example, on x86, PCIe-based ethernet interfaces will be named starting from eth0 in the order they are probed. This is a problem for many devices supported explicitly by OpenWrt which have hard-wired, standalone or on-CPU NICs not supported by DSA (which is usually used to rename the ports based on their ostensible function). To fix this, add a mapping between ethernet device name and sysfs device path to board.json; this allows us to configure ethernet device names we know about for a given board so that they correspond to external labeling.

* 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: 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.

| | | | | | | | | | | | | | | | | Prepares code for ubirename-based safe sysupgrade implementation. Fixes several issues: - the special CI_KERNPART value "none" is ignored if an MTD partition named "none" exists - misleading variable names (such as has_kernel to mean "tar has kernel and it should not be written to an MTD partition but a UBI volume") - inconsistent treatment of zero-length tar member files - inconsistent meaning of "0" and "" variable values - redundant operations (unneeded untaring, repeated untaring, unneeded partition lookups) - inconsistent variable quoting Signed-off-by: Rodrigo Balerdi <lanchon@gmail.com>
