* bcm47xx: disable image for Linksys WRT160n v3Adrian Schmutzler2020-07-131-0/+1
| | | | | | | | | | | | The device can only hold 3.6 MB, but newer images (since 18.06) are bigger, so flashing a new version fails. This disables default build for this device based on the bug report referenced below. Fixes: FS#1963 Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: consolidate Netgear devices for mt7628Adrian Schmutzler2020-07-137-283/+151
| | | | | | | | | | | | | | | This creates a common DTSI and shared image definition for the relatively similar Netgear devices for mt7628 platform. As a side effect, this raises SPI flash frequency for the R6120, as it's expected to work there as well if it works for R6080 and R6020. Based on the data from the other devices, it also seems probable the 5g MAC address for R6120 could be extracted from the caldata, and the mtd-mac-address there could be dropped.

* wireguard: bump to 1.0.20200712Jason A. Donenfeld2020-07-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This release brings parity with the commits Linus released a few hours ago into 5.8-rc5. * receive: account for napi_gro_receive never returning GRO_DROP The napi_gro_receive function no longer returns GRO_DROP ever, making handling GRO_DROP dead code. This commit removes that dead code. Further, it's not even clear that device drivers have any business in taking action after passing off received packets; that's arguably out of their hands. * device: implement header_ops->parse_protocol for AF_PACKET WireGuard uses skb->protocol to determine packet type, and bails out if it's not set or set to something it's not expecting. For AF_PACKET injection, we need to support its call chain of: packet_sendmsg -> packet_snd -> packet_parse_headers -> dev_parse_header_protocol -> parse_protocol Without a valid parse_protocol, this returns zero, and wireguard then rejects the skb. So, this wires up the ip_tunnel handler for layer 3 packets for that case. * queueing: make use of ip_tunnel_parse_protocol Now that wg_examine_packet_protocol has been added for general consumption as ip_tunnel_parse_protocol, it's possible to remove wg_examine_packet_protocol and simply use the new ip_tunnel_parse_protocol function directly. * compat: backport ip_tunnel_parse_protocol and ip_tunnel_header_ops These are required for moving wg_examine_packet_protocol out of wireguard and into upstream.

* mvebu: fix support for Marvell 8040 MACCHIATOBinAdrian Schmutzler2020-07-115-6/+20
| | | | | | | | | | | | | | | | | | | | | | Between kernels 4.20 and 5.0, a new variant of this board has been introduced ("Single Shot"), and the existing one has been renamed with the appendix "Double Shot". [1] This also adjusted the first compatible in the list: marvell,armada8040-mcbin -> marvell,armada8040-mcbin-doubleshot This patch updates the OpenWrt implementation of this device by adjusting the relevant references to that compatible (i.e., our board name). To still provide support for 4.19 with our setup, this adds a small patch to change the compatible there as well.

* build: improve ccache supportRoman Yeryomin2020-07-119-10/+29
| | | | | | | | | | | | | | | | | | Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin <roman@advem.lv>

* busybox: store applet usage messages uncompressedRui Salvaterra2020-07-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rootfs squashfs is already highly (XZ) compressed. Storing the applet messages in compressed form will increase the entropy and reduce the overall image compression ratio. Size diffs (compressed vs uncompressed): busybox (the executable): 364596 vs 384804 bytes. OpenWrt target images (the kernel image is unchanged, obviously): omnia-medkit-openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs.tar.gz: 9163597 vs 9162531 bytes (1066 bytes difference). openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs-kernel.bin: 9161688 vs 9160600 bytes (1088 bytes difference). openwrt-mvebu-cortexa9-cznic_turris-omnia-sysupgrade.img.gz: 9729550 vs 9729230 bytes (320 bytes difference). All in all, we save just a little bit over 1 kiB. As an added bonus, we also don't have to decompress the messages twice, (first from squashfs, then from the bzip2 message storage).

| | | | | | | | | | | | | | | | | | | | Instead of using xargs to pass a huge number of files to script/ipkg-remove, which will usually pick only one, use a more restrictive wildcard so that, currently, at the most 325 files are examined, instead of up to over 2,300. The 325-file package is python, which is picking up python3* ipks. It is about to be removed. Runner-up is ddns-scripts with 7 files. This makes a second run of make package/luci/compile go from real 16.40s; user 17.42s; sys 2.73s to real 10.71s; user 9.51s; sys 1.27s There is a caveat though: if one were to remove the ABI_VERSION of a package that ends in a digit [0-9], then the old package ipk will not be removed from the bin directory by make package/abc2/clean.
