SFE update in this build (k3.10+ for BCM).

Downloads: (if a link doesn't work, try another)
https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2019/06-03-2019-r39927/
ftp://ftp.dd-wrt.com/betas/2019/06-03-2019-r39927/
Alternate link: DD-WRT website
Note: to use wget (or curl) for CLI flash (`write {f/w} linux`), change the https to http (or use ftp instead)

Changelogs:
SVN* changelog since last build: 39884
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 build 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. Since 39469, udhcpd was removed and replaced with the already present dnsmasq, and PIE qdisc was added for some builds.
5. Policy-Based Routing with SFE enabled was fixed in r39556: 5986 and 5900
6. k2.4 (broadcom/) builds were fixed in 39715 (broken in 39144 through 39654)

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 to be fixed for some routers (different kernels, modes, and radios) since build 39508.

Important: if any issues are found, please provide log info (GUI syslog, `dmesg`, `cat /var/log/messages`).
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]

Router Model: Linksys E2000 (converted N320)

Firmware Version: DD-WRT v3.0-r39927 mega (06/03/19)
Kernel Version: Linux 3.10.108-d8 #24753 Mon Jun 3 13:41:54 CEST 2019 mips

Upgraded: from DD-WRT v3.0-r39884 mega (05/30/19) with IE, Firefox seems flaky when updating
Reset: No, not this time

Status: Up and running for 4 hours, basic setup as Gateway, static leases, OpenVPN client (tun) (on PIA) up and running, VPN download speed 5-6 Mb/s, Wifi 2,4GHz working, VAP bridged and unbridged working without any workarounds!!.
OpenVPN server working.

I have tested the new unidirectional firewall (Inbound Firewall on TUN) for OVPN client and can see that the necessary firewall rules are in place, good job!

Errors: No, Seems like a good build

Big Thanks to the devs!!

Router/Version: N66U
File: ftp.dd-wrt.com/betas/2019/06-03-2019-r39927/broadcom_K3X/dd-wrt.v24-39927_NEWD-2_K3.x_mega_RT-N66U.trx
Kernel: 3.10.108-d8 #24753
Mode: gateway, 2.4(HT20)+5(HT40)
Status: good, 1hr uptime

39572 -> 39927
* no nas/timer/rekey events [so far]
* iot 2.4GHz devices ok
* balanced interractive+streaming wifi [vegas, no QoS]

I'll update after a bit of soak.

Post Soak:
* 5Ghz 157+161 RX:12MB/s TX:16MB/s [server <> wifi]
* RX:112MB/s TX:111MB/s [GbE <> GbE]
* nas/timer/rekey events:
4.53 million "timer : #nnnn" messages over a 4.4 hour period of normal use.
Unlike before, no timer+<hang|crash|reboot> events.

* nas/timer spew averaged 286 messages/sec with bursts of 4600 messages/sec to both local and remote logs:
Code:
$ sudo egrep 'Jun  6 .*\.2 .*(: #0 | event)' /var/log/messages

Update 2: After turning on the nas/timer watchdog script, events are caught and nas/wl restarted in 2-3 timer cycles rather than thousands of cycles. Restarting nas/wl early appears to result in only 3-6 events per day. Or it is a coincidence.
