Samba 4.12 is also out today and has a interesting new VFS module, that might help on heavy threaded workloads. Should not matter for bulk transfers from what i understand.
'io_uring' vfs module
---------------------
The module makes use of the new io_uring infrastructure
(intruduced in Linux 5.1), see https://lwn.net/Articles/776703/
Currently this implements SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND/RECV
and avoids the overhead of the userspace threadpool in the default
vfs backend. See also vfs_io_uring(8).
So keep this new module io_uring in mind if i update to 4.12 and we have kernel 5.1 support.
I have kept SQM activated after update and additionally enabled offloading on my WRT1900ACS.
At least not seen anything breaking so far.
But also cannot really prove that SQM is still working as before. I'm mainly using it to throttle down my guest Wifi but didn't have many "leeching guests" since the update ...
My WRT32X with the stock Linksys firmware (which hasn't been updated in 2 years thanks to that garbage company) maxed out my 200Mbit cable modem at full A+ ratings for bufferbloat, etc. on www.dslreports.com/speedtest. I can confirm that with these newer OpenWrt builds enabling SQM and using software offloading finally gets similar A+ results most of the time.
Samba is also working well, using my external 3TB 5400rpm USB 3.0 drive I get in the 85 MB/s range. I reset settings not sure what was happening when I spoke on it being slow before. Transfers are so fast and Kodi works perfectly on my Shield TV for example.
Are you using QoS with the stock firmware? Otherwise it sounds like that your cable modem is doing some sort of QoS/Prioritization or your ISP behind the scenes...
I'm going to give SQM+Software Flow Offloading a try and I'll report if I encounter any issues. SQM is kinda CPU intensive so it would be quite nice to save a little bit CPU usage while SQM is active. ~15% does sound pretty good imho!
It's not my cable modem, I use a pretty common SB6183. For years I used an R7000 router and it never got over B+ bufferbloat with the same modem and same internet. I got the WRT32X (off Amazon renewed for $100) 1-2 years ago and it's been A+ Bufferbloat and Quality ratings with the Linksys OEM firmware. Their firmware hasn't been updated in 2 years but it's still decent and based off of OpenWrt anyway. Now also getting more than my rated ISP speed and A+ on OpenWrt with SQM and software offloading enabled. Can't speak to what is happening behind the scenes other than that. A+/A+ should be expected these days though with these routers.
Just updated to davidc502 from 19.07.1 on wrt32x runs flawless.. as a AP wifi is working well with offloading + sqm thnks for all your hard work. 19.07.1 is not that far back One thing I did like is all of your basic pkgs are right out of the box . I went to facory. then I restored a backup of 19.07.1 work like a charm.
Just noticed yesterday that my VOIP handset was no longer registering with Sipgate. It's a Siemens N510 Pro and was showing "registration failed" in the web UI for the basestation. This behaviour has only manifested since recently updating my WRT32X to build r12235. Previously i had been on r10307 since June last year, so a big jump, I know...
I did a little tcpdump'ing (VOIP telephony is my day job, lucky me!) and saw REGISTER requests going out but nothing coming back in. Previously I had no port forwards for this device configured and everything worked fine. I set up SIP and RTP port forwards to my basestation as per the Sipgate FAQs and everything is working fine again now.
So, no help required or problem, just posting this in case anyone else runs into a similar issue as something has obviously changed.
EDIT Spoiler: it was Software Flow Offloading. I've now disabled it and the VOIP service is registering without and SIP port forwards.
There is a lets encrypt issue that could affect 3 million sites this afternoon and was due to a bug.
There is a tool to see if a site is affected, and fortunately the dc502wrt.org is not. - "The certificate currently available on dc502wrt.org is OK. It is not one of the certificates affected by the Let's Encrypt CAA rechecking problem."
I'm using a dedicated voip device in my network and never had problems with my SIP regs but your report coulp help if I run into problems after upgrading to the latest firmware (I'm still on r11829).
Btw, I'm using the following option on my voip device: Keep port forwarding of the Internet router active for telephony (every 30 seconds)
Maybe thats why I never ran into any problems with voip...?
edit: Just upgraded to the latest build and my numbers on my voip device are still working fine without the need of any manual port forwarding.
Everything else is also working fine (port forwarding, wireless, SQM, aso)!
Hi all!
I'm considering upgrading to r12394, for the sake of offloading and SQM - but please can someone explain (in one sentence) if/why I should enable both for a better WiFi experience?
Also, I rely on port forwarding for my servers and I read that there's an ongoing issue with that in r12394. Is everyone affected?
Yes upgrade, and yes enable software flow offloading (hardware offloading is not supported) and SQM. Just know this will have no impact on WiFi as the open source driver mwlwifi is abandoned. As a result there has been no WiFi improvement for our devices for over a year other than a firmware update for WRT3200ACM / WRT32X which didn't really do anything. Not sure about the port forwarding issue.
Issues with port forwarding seems to be (wan) setup related. No issues here @pppoe....
SQM with software flow offloading also seems to work fine but maybe there are some issues which I haven't encounterd yet. I'm using Layer_cake @diffserv4 + some DSCP tags for the egress.
