Repository: Trac SVN changelog since last build r43502 (GitHub mirror)

Notes:
• r41664 or later for SFE NAT (k3.2+), KRACK (k24+), PBR+SFE, CAKE & FQ_CODEL_FAST (reset!), GTK Rekey timer fixes.
• Reset button was broken at 40571, then fixed in build r40750.
• Experimental build option for Broadcom 8MB+ K2.x devices (limited currently): broadcom_K3X_mipsel32r1
• CVE-2019-14899 VPN fix (applicability depends on VPN setup) and GUI toggle. 6920, 6928, 6931, 6932 (WIP 7040)
• In-kernel Samba has been implemented this year and default min/max versions have changed 6954, 6957, with WSD support.
• Broadcom MIPS devices are now on kernel 4.4. N66U/AC66U half memory is fully resolved.
• Local DNS option removed from Services->DNSMasq in changesets 43080 and 43081; ref: #7092
• DHCP and DNS help (English) updated in 43083; ref: #7091
• WAN lease time approaching zero bug on WRT54* devices fixed in 43191; ref: #6456
• Images for WNR3500Lv2 (BRCM NAND flash crash bug) fixed in 43219 (43217); ref: #7098
• WireGuard: Policy Based Routing, Kill Switch, Inbound Firewall, Naming of Peers, Status, Key, Guides. Thanks egc!

Issues, observations, and/or workarounds reported:
• DNScrypt 1.95 can still be used in the GUI but v2 (not compatible) requires Golang and thus Entware. 6246
• WDS does not work on Broadcom ARM devices (only MIPS<->MIPS) and bridge modes on k4.4 devices may sometimes work in some configurations in certain builds but are not supported by the bcmdhd driver. Use client or repeater instead.
• VAPs not working at boot fixed for unbridged VAPs with r40564:40566. Workaround startup command:
sleep 10;stopservice nas;stopservice wlconf;startservice wlconf;startservice nas (there are a few alternatives, search).
• If start-up scripts do not work from USB add a delay (e.g. wait script or 'sleep 25').

Important:
• If reporting issues provide applicable info: 'dmesg', 'cat /tmp/var/log/messages', syslog/serial output, strace etc.
• For firewall issues provide 'iptables -L', 'iptables -t nat -L' and the /tmp/.ipt file.
• Search existing SVN tickets before opening a new one. Before reporting, reset and manually setup (no nvram backup).
• Be sure to include operating and wireless modes (Gateway, AP, CB, etc.) along with relevant configuration information.

running for 10hrs, memory usage stable, CPU running nearly idle, Chipset temperatures at ~50±1°C.

one observation - PPPOE connect is taking longer till 43502 it was taking 30sec to 1 minute to connect after reboot, now taking around 2-3 minutes.

Thank you BrainSlayer for Wonderful firmware.

Thanks kernel-panic & egc for your help in forums. and egc's wireguard setup guide is one to preserve for long, it helped me setup wireguard in minutes.
