* scripts/download.pl: fix downloads with wgetPetr Štetiar2022-09-161-2/+8
| | | | | | | | | | | | | | | | | | | | | Several users of wget for downloads (curl is not available in the system) have reported broken download functionality: wget --tries=5 --timeout=20 --output-document=- https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.142.tar.xz http://: Invalid host name. Thats all happening due to '' was passed as an argument, which got later expanded to http://. In the context of a list constructor '' is not nothing, it is an empty string element. So fix it by using () as it will yield "nothing" and thus not introduce an empty string element.

* scripts/download.pl: silence can't exec curl warningPetr Štetiar2022-09-161-1/+1
| | | | | | | | | | | | When running build in verbose mode `make V=s` we can see a lot of following warnings when curl is not available in the system: Can't exec "curl": No such file or directory at scripts/download.pl line 77.

* scripts: always check certificatesJosh Roys2022-09-161-2/+4
| | | | | | | | | | | | | | | | Remove flags from wget and curl instructing them to ignore bad server certificates. Although other mechanisms can protect against malicious modifications of downloads, other vectors of attack may be available to an adversary. TLS certificate verification can be disabled by turning oof the "Enable TLS certificate verification during package download" option enabled by default in the "Global build settings" in "make menuconfig" Signed-off-by: Josh Roys <roysjosh@gmail.com> [ add additional info on how to disable this option ] Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> (cherry picked from commit 90c6e3aedf167b0ae1baf376e7800a631681e69a)
* scripts: xxdi.pl: add xxd -i compat modePetr Štetiar2022-09-161-18/+19
| | | | | | | | | | | | So it can serve as a standalone drop in replacement for xxd utility used currently mostly in U-Boot packages with `xxd -i` mode which outputs C include file style, with aim for byte to byte identical output, so the eventual difference in the generated output is easily spottable.

* image: add support for Netgear encrypted imageWenli Looi2022-07-211-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | Netgear encrypted image is used in various devices including WAX202, WAX206, and EX6400v3. This image format also requires a dummy squashfs4 image which is added here as well. References in WAX202 GPL source: https://www.downloads.netgear.com/files/GPL/WAX202_V1.0.5.1_Source.rar * openwrt/bootloader/u-boot-mt7621-2018.09-gitb178829-20200526/board/ralink/common/dual_image.c Bootloader code that verifies the presence of a squashfs4 image, thus a dummy image is added here. * openwrt/tools/imgencoder/src/gj_enc.c Contains code that generates the encrypted image. There is support for adding an RSA signature, but it does not look like the signature is verified by the stock firmware or bootloader. * openwrt/tools/imgencoder/src/imagekey.h Contains the encryption key and IV. It appears the same key/IV is used for other Netgear devices including WAX206 and EX6400v3.

* scripts/gen_image_generic.sh: fix order of files in EFI bootfsDaniel Golle2022-04-151-2/+19
| | | | | | | | | | | | | mtools recursive copy (mcopy -s ...) is using READDIR(3) to iterate over the directory entries, hence they end up in the FAT filesystem in traversal order which breaks reproducibility (rather than being added to the FAT filesystem in a reproducible order). Implement recursive copy in gen_image_generic.sh in Shell code instead, as in that way we can force files to be copied in reproducible order.

* build: store sha256_unsigned in JSONPaul Spooren2022-04-061-4/+12
| | | | | | | | | | | | | Introduce `sha256_unsigned` which is a checksum of the image _before_ a signature is attached. This is helpful to compare image reproducibility. Since the `.sha256sum` file is located in the $(KDIR) folder, switch $(BIN_DIR) with $(KDIR) to simplify the code. The value of $(BIN_DIR) itself is not stored inside the resulting JSON file, so it can be replaced.

* check-toolchain-clean.sh: workaround stray rebuildsPetr Štetiar2022-02-281-2/+7
| | | | | | | | | | | | | | | | It seems, that there are currently some unhandled corner cases in which `.toolchain_build_ver` results in empty file and thus forcing rebuilds, even if the toolchain was build correctly just a few moments ago. Until proper fix is found, workaround that by checking for this corner case and simply populate `.toolchain_build_ver` file. While at it, improve the UX and display version mismatch, so it's more clear what has forced the rebuild: "Toolchain build version changed (11.2.0-1 != ), running make targetclean" References: https://gitlab.com/ynezz/openwrt/-/jobs/2133332533/raw Signed-off-by: Petr Štetiar <ynezz@true.cz>

* feeds: use git-src-full to allow Git versioningPaul Spooren2022-02-151-2/+2
| | | | | | | | | | | | | | | Both $(AUTORELEASE) and $(PKG_SRC_VERSION) (from luci.git) use the Git log to determine releases and package timestamps.

* base-files: add eMMC sysupgrade supportEnrico Mioso2021-12-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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 Tintel2021-08-071-0/+1
| | | | | | | | 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>
