[WARNING]: This thread is only for feedback on this beta release for developers and the community's benefit.
DO NOT flash this beta release unless you understand the risks involved and specific device 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: (DD-WRT website) HTTPS & FTP (try another if a link doesn't work)

CLI Flash: 'cd /tmp' then 'wget {file URL}' (or 'curl -k {file URL} -o {file}') with http (not https) or ftp. Then 'write {file} linux'.

Repository: Trac SVN changelog since last build r43652 (GitHub mirror)

Notes:
• 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.
• VAP issue is fixed! For any Wireless Mode, create a VAP and both ath0/ath1 should now function properly.
• Local DNS option removed from Services->DNSMasq in changesets 43080 and 43081; ref: #7092
• DHCP and DNS help (English) updated in 43083; ref: #7091
WireGuard 1.0.20200623: PBR, Kill Switch, Inbound Firewall, Naming of Peers, Status, Key, Guides. Thanks egc!

Issues:
• There may be remaining issues for Samba (for example NTFS), with frequent updates.

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.

Code:
[b]Router/Version: [/b]
[b]File/Kernel: [/b]
[b]Previous/Reset: [/b]

This build bricked my WZR-600DHP. Previous build was 43652 and was working well. I let the router sit for 10 min prior to doing a power cycle with no luck. Off to attempt a recovery.

Did you try doing a reset? There were some devices, I think mostly Ralink/MediaTek, that got a driver upgrade. Not sure if any of the Atheros Buffalo devices were part of that or not.

I thought you had to re-flash the entire image, not webupgrade on x86. Not sure how it magically detected the hardware change and balked.

I did not perform a reset when flashing from 43652. I flash my routers like a layman would to find issues. I did try a 30-30-30 after it bricked but no luck. trying to get the TFTP timing down to recover the router, no luck yet.

yes reflash onto the new drive, but it picks up the different drive (serial # i guess?) and refuses to activate with previous key.

When browsing the Samba share, in particular if from Windows Explorer I:
(Windows10, ver 1909)
1. browse to, say \\192.168.1.1\usb_dsk\videos
2. open a file
3. In Windows Explorer address bar I click on \\192.168.1.1 part of the address

So far, I have not been able to make SMB make the kernel crash!
[Edit] It did not take long. It still crashes. See next post.[/Edit]

Thanks BS for all the effort!

What I did:
1. connect to Samba share from Win10
2. Open/close some files
3. turn off WiFi on the client (Win10)
4. Wait a few seconds
5. turn WiFi back on on the client
6. wait a few seconds.
7. Kernel crashes

please try the attached image for the r7800 and gimme feedback if it solves your problem. if not, can you provide a tcpdump/wireshark capture if your samba traffic at the time the problem occures?

Used as AP, Router, SMB, FTP, DHCP.
External USB HDD (ext4)

Spoke too soon. Sad
Samba still crashes the router.

What I did:
1. connect to Samba share from Win10
2. Open/close some files
3. turn off WiFi on the client (Win10)
4. Wait a few seconds
5. turn WiFi back on on the client
6. wait a few seconds.
7. Kernel crashes

Tried this build, No crash Observed which there earlier.

one observation, while transferring the file to USB attached to router from windows 10 , router CPU usage reaches 100%, free memory reduces to 9%. the file transfer happens successfully, tried both to & fro from Samba share. the only thing i found is CPU usage took about 1 Hour to reduce, but reduced till 85% only. Memory is not freed after transfer is complete. needed a router reboot to restore memory and CPU usage.
Frankly speaking except high CPU usage and memory usage everything worked.
