Welcome to Broadcom r47900 beta release thread for reporting, feedback to developers & community benefit.
Please do not flash builds until installation is understood, risks involved and device specific recovery methods.
Avoid discussions, create threads for questions, general problems or use search; this thread is not for support.
Please list router model & revision, operating & wireless mode(s) and exact filename/firmware image flashed.


Downloads: HTTPS, FTP

CLI Flash: 'cd /tmp' then 'wget {file URL}' (http only) or 'curl -O {file URL}' (http, https, ftp). 'write {file} linux' then 'reboot'.

Trac SVN: repository since last build r47874 (mirror)

OpenVPN 2.5.5: Changelog, Guides, Server, PBR, DNS, Kill Switch, Watchdog, Reverse PBR, Client, Multiple, tips & scripts.
WireGuard 1.0.20211208/Tools: Changelog, Guides, Client, Server, Advanced, PBR, KS, tips and scripts. Thanks BS & egc!

Notes:
Experimental for 8MB+ K2.x devices: broadcom_K3X_mipsel32r1. • MIPS @ kernel 4.4. • TP-Link Archer C8 v2, v3 support.
MiniDLNA, CoovaChilli, Privoxy, iperf3, CAKE, FreeRADIUS, dnsmasq, Unbound, Tor, Squid, Asterisk, OpenSSL, BusyBox, SmartDNS, curl, ProFTPD, mac80211
In-kernel Samba (ksmbd 3.4.2+++) guest behavior now selectable. • WSD updateANTFS/NTFS3 kernel mode driver+++
CVE-2020-26147, CVE-2020-24586, CVE-2020-24587 & CVE-2020-24588 fragattack fixed. • Broadcom swconfig supported.
• 'Assign WAN port to Switch' gone, set Connection Type Disabled. • WebUI MAC Filtering (47184-47205). • Sputnik removed.
• 'Ignore WAN DNS' also ignores WAN domain. • Milkfish removed.
New DD-WRT inspired themes conversion by the-joker & BrainSlayer, micro builds excluded, see UI theme test info thread.
401 bad request: Ethernet WebUI -> Wireless -> Basic Settings -> Advanced Settings -> Wireless GUI Access Enable, Save

Issues, observations, and/or workarounds reported:
WebUI: Clear history or use a portable. Temporary cache bypass: Ctrl+F5, Cmd+Shift+R or new private window/incognito.
DNScrypt 1.95 can still be used in WebUI but v2 (not compatible) requires Golang and thus Entware. See Trac ticket #6246.
WDS does not work on Broadcom ARM devices (only MIPS<->MIPS) & bridge modes on k4.4 devices may sometimes work
in some configurations for certain builds but are not supported by the bcmdhd driver. Try client or repeater modes, but YMMV.
VAPs not working at boot are fixed, both unbridged (r40634) and bridged (r47822). Please test, remove startup commands.
If startup scripts do not work from USB add delay (wait script), sleep 25 or try Administration -> Commands -> Save USB.
Broadcom ARM devices if 5 GHz channels are missing via Telnet/SSH: 'nvram set brcm_unlock=1' 'nvram commit' 'reboot'.
Please report findings with steps needed to reproduce, configuration, clients, output, logs and important information below!

Important:
• For issues provide applicable info: 'dmesg' 'cat /tmp/var/log/messages', syslog klog, serial, strace, tcpdump, wireshark etc.
• Any firewall NAT or WAN issues, show output: 'iptables -vnL' 'iptables -t nat -vnL' 'iptables -t mangle -vnL' and /tmp/.ipt file.
• Gremlins: reset & configure manually, not restore a backup. Reboot. Search Trac & discuss in forum before opening tickets.
• Please include operating & wireless modes (e.g. Gateway, Router, AP, CB, WDS, Mesh) & relevant configuration information.

Code:
[b]Router/Version: [/b]

I've noticed in recent versions that there are some restarts every time ntp runs. Is this correct behavior?

@turbowells:Thank you for asking about this, but I was asked for people to refrain from public comments about syslog entries they do not understand if they do not understand how the firmware works; instead focus on functionality issues, primarily and cosmetic (quite) secondarily. Thanks for understanding.

this is intentional. to flush conntrack entries from sfe module and this happens only on time change. in this case the whole firewall rules are loaded otherwise time scheduled filters will not works.

Start a new thread with you problem and post screen prints of your settings, if I remember correctly the 7000P is a difficult router (regarding Wifi which is connected via DHD) so a bug is not impossible

Router/Version: Asus RT-N66R
File: dd-wrt.v24-47900_NEWD-2_K3.x-big-RT-N66U.trx
Kernel: Linux 4.4.294 #13224 Mon Dec 20 06:40:14 +07 2021 mips
Previous: dd-wrt.v24-47665_NEWD-2_K3.x-big-RT-N66U.trx
Reset: No (upgraded via web interface with Firefox 95.0.2 (64-bit))
Mode: Gateway Router (with WiFi disabled; separate AP connected via LAN)
Status: All seem to be working so far. Smile
Uptime: >25 hours
Temperatures: Not available [WiFi disabled]

Note: Not a bug/problem, just an observational change in operations on adding Static Leases via the web interface. The colon ':' characters are not necessary/acceptable now for the MAC Address field entries. For example, previously the MAC Address was entered as "XX:XX:XX:XX:XX:XX", whereas now just "XXXXXXXXXXXX" is accepted. The following error message will appear in a pop-up if using the previous format:

MAC AddressInvalid Character ":"

This change may have been instituted in earlier builds but I just noticed now when I'd to add a static IP for a newly connected network device. Not an issue, all's well.

interesting observation/good find Smile

Not noticed that earlier as most users just add the static leases in the Additional DNSMasq options like:
Code:
dhcp-host=08:97:98:XX:XX:XX,192.168.13.59,NITRO,1440m
which is much easier
