Note: for wget (or curl) with CLI flash (`write {f/w} linux`), change the https to http, use `curl -k {link} -o {file}`, or use ftp

Changelogs:
SVN* changelog since last build: 40784
Summary: (deprecated after 29739)
*Github mirror: https://github.com/mirror/dd-wrt/

Notes:
1. SFE accelerated NAT is in 33006+ builds but only in kernel 3.2 and newer
2. 'KRACK' vulnerability fixes were completed in r33678 for Broadcom, including k26 (33655) & k24 (33656); use 33772 or later.
3. 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 as WDS doesn't work with Broadcom ARM either (see Issues below).
4. PBR/UDP with SFE working again since r40513 (see 6729)
4. CAKE scheduler added since r40547 (see 5796)

Issues, observations, and/or workarounds reported:
1. Trendnet 81*DRU models are missing factory-to-flash
2. DNScrypt is mostly only using v2 protocols now, but requires Golang that DD can't use: 6246
3. WDS does not work on Broadcom ARM devices (only MIPS<->MIPS)
4. K2.6 builds are broken since 38253(?) (GUI issues): 6538
5. VAPs not working at boot; workaround startup command:
sleep 10;stopservice nas;stopservice wlconf;startservice wlconf;startservice nas
This appears fixed (only for unbridged VAPs?) with r40564:40566...

Important: if reporting any issues, provide applicable info (GUI syslog, `dmesg`, `cat /var/log/messages`, etc.)
Or put into SVN ticket. For firewall issues, also provide "iptables" info (`iptables -L`, `iptables -t nat -L`, & the /tmp/.ipt file).

Template to copy (after "Code:") for posting issues, be sure to include the mode in use (gateway, AP, CB, etc.):
Code:
[b]Router/Version: [/b]
[b]File: [/b]
[b]Kernel: [/b]
[b]Mode: [/b]
[b]Status: [/b]

WARNING: This thread is to report on flashing this experimental test build, providing important info for both developers and users. Always state your hardware model, version, mode (e.g. Repeater) and SPECIFIC build (e.g. 33555_NEWD-2_K3.x_mega-nv64k.bin). Please avoid discussions and create a new thread to discuss specific problems or questions, as this thread is for reporting, not support. Posts may be deleted or moved to keep this thread manageable and useful. If you don't understand the risks or what to flash and how, with a means of recovery if it bricks, do NOT flash this experimental test build.

Be very wary...the commits after this build revert a bunch of k3.10 and k4.4 changes; e.g. from 40851 for k3.10. I won't be trying it on my K3X stuff...

does this apply to a netgear r7000p?


*
from context it appears the k3.10 & k4.4 are different

i know im broadcom arm but didn't know if the other was a subset or different thing entirely.

**the QoS issues were just with fq codel fast correct?

The driver commits and reverts have been ongoing over the past few builds, if you have been paying attention. QoS and Broadcom-ARM crash related issues.

Router/Version: Netgear R7000
Firmware: DD-WRT v3.0-r40854 std (08/29/19)
Kernel: Linux 4.4.190 #1092 SMP Thu Aug 29 11:32:59 +04 2019 armv7l
Previous: r40784
Mode/Status: Gateway / working
Reset: no
Issues/Errors: Working well so far. A cursory glance at the change logs didn't reveal anything obvious for fq_codel_fast, so haven't tested that until I have more time.

Edit... tried fq_codel_fast and it still causes a soft-brick. Also, not sure if my R7000's reset button is flaky, but my device appears to require a power cycle before the reset button functions. Order of operations: enable fq_codel_fast > save > enable > *soft brick* > press reset button (doesn't work) > cycle power > still soft-bricked > reset button (works) > reconfigure from defaults > celebrate.

Edit (not specific to this build because I've observed this previously), but... SFE adds 10ms latency to my setup, based on http://www.dslreports.com/speedtest results...

SFE (enable) + fq_codel @200000kbps = 48ms bufferbloat average download latency
SFE (disable) + fq_codel @200000kbps = 38ms bufferbloat average download latency

Bonus...

SFE (disable) + CAKE @200000kbps = 55ms bufferbloat average download latency

Uptime: 23min
Temperatures: CPU 69.7 °C / WL0 48.5 °C / WL1 54.5 °C

Router/Version: Netgear R6400v2 Board ID 30
Firmware: DD-WRT v3.0-r40854 std (08/29/19)
Kernel: Linux 4.4.190 #1092 SMP Thu Aug 29 11:32:59 +04 2019 armv7l
Previous: r40784
Mode/Status: Gateway, QoS (HTB + CAKE), AP, VAP, dnsmasq
Reset: nvram erase && reboot
Errors/Issues: After reset and re-entering settings it's working fine. Looks like SFE is enabled by default on this build so it needs a reset to unload correctly the module and allow QoS to work at full speed.

Uptime: 2 hours
Temps: CPU 74.1 °C / WL0 47.1 °C / WL1 54.0 °C

The http link is wrong, there is an extra 0 in the build directory you might want to correct.
