[illumos-gate] 17473 Update JEDEC vendors to JEP106BM -- Robert Mustacchi <rm⊙fo>

[illumos-gate] 17474 June 2025 hwdata update -- Robert Mustacchi <rm⊙fo>

erm, how do I initialize my iscsi initiator iqn? iscsiadm list initiator-node shows no value for "Initiator node name"

and since I use host groups for the views of iscsi luns, I need the iqn of this client...

I think our iscsi stack is not super solid...on the target side, I have one target with 65534 sessions (probably max) and I can't offline that target, I can't even stop the target service because the stop method hangs

and according to src.illumos.org/source/xref/illumos…scsitsvc/iscsitsvc.c?r=607aa931#170 it just opens the device and does an ioctl on it

which brings me to the conclusion that a reboot will be the only solution...correct?

probably... and yes iscsiadm list initiator-node should show the iqn, but it does not.

tsoome_: oh, same for you? is there another way to get the initiator iqn?

I did pick it from target side, it did appear on unlimited lun or something

tsoome_: hehe, ok

ok, we do get nice L"iqn.1986-03.com.sun:01:583fa0d80bfe.6769fa50" from ioctl(), we use vswprintf() in libSwprintf() to store this and end up having L"\x2e6e7169\x36383931\x2e33302d\x2e6d6f63\x3a6e7573\x353a3130\x61663338\x30386430\x2e656662\x39363736\x30356166" and fprintf("%ws") prints basically garbage (11 times byte 0 according to hexdump -C).

oh, how sweet...

either vswprintf or fprintf does something bad; fprintf("%ws") does print L"iqn.1986-03.com.sun:01:583fa0d80bfe.6769fa50" as expected, however.

more serious is the issue that I have 65534 sessions on this target - probably because the initiators do not log out correctly until all sessions are in use...

and of course then the target service is not even able to offline that target anymore

I do not know the details about iscsi protocol, but I'm pretty sure the sessions should be possible to get reaped...

I think also the target side should reap those

yep, in networked environment you can not assume every client system will end the session "correctly".

it seems, in iscsiadm, the fprintf("%ws") is to be blamed, wprintf(L"%s") does print the iqn correctly.

tsoome_: shall I open the bug and send a patch, or do you want to do it yourself?

please do - feel free to use my findings:) also it may be Woodstock can tell thing or two about it

ok, I'll take notes

I'm in a bit of in middle of other issue:D

gotcha ;)

I will also not file it before monday I guess...I need to file travel claims

got illumos installed on a small Alder Lake intel system that I'm bringing in as a router. some console quirks (serial console wasn't quite functional during install) but seems to be working.

(protectli VP6650 with coreboot firmware with an intel i5-1235U cpu). connected to a newly installed 10G fiber service (sonic.com) that.. isn't working with a 10G link speed but seems to be ok at 2.5G

NIC ?

Alder lake small means it's probably a I225 or I226 (aka. igc(4D)).

danmcd: 4x I226-V (copper), 2x X710 10Gb SFP+

this cpu has 2 hyperthreaded "performance" cores and 8 single-thread "efficiency" cores. Seems to be behaving itself with all 12 threads enabled.

(but haven't really pushed it)

did fall back from 10 to 2.5, skipped 5G?

no. doesn't work when plugged into a 10G interface (with a different machine it eventually got a dhcp lease but had 85% to 95% packet loss)

when plugged into a 1G port on the other machine it works fine at 1G. when plugged into a 2.5G igc port on this machine it also works fine.

I see...

the ONT Sonic installed looks to be an Adtran 632V

(and unless I'm missing something it doesn't look like I can force the X710 into 2.5G or 5G mode - might be a limitation of the particular 10GbaseT sfp I have)

might be, yep.

okay, this is weird. connected it to a switch that is 1/2.5/5/10 capable and set the switch advertise only 2.5G. switch thinks the link came up at 2.5; illumos on the other end thinks it's 10G

iperf agrees with the switch..

that may hint why 10G has problems?

no, it seems to work OK when 10G is enabled on the switch

You're plugging in one of the X710s to the switch, I'm assuming?

Or the I226/igc? If the igc, I think we only support 2.5G on that. If rmustacc is here and has cycles he may have more useful data in his L1-3 caches.

Correction: I226 ONLY supports up to 2.5Gbit.

I'm trying a bunch of different combinations to figure out what works and doesn't work before I call sonic.

ideal config is one X710 connected to sonic, the other to a switch.

current config is one X710 to switch, one igc to sonic at 2.5G

What does `prtconf -v | grep X7` say? Model & PCIe ID would be useful. I know there's some Intel common code that needs updating in i40e(4D) at some point. (It might actually fix fenix illumos#13230 ?!?)

code review '13230' not found...

I want to test one X710 to switch, other X710 at 2.5G to sonic just to fully cover the bases

value='Ethernet Controller X710 for 10GbE SFP+'

value='Ethernet Converged Network Adapter X710'

value='Ethernet Controller X710 for 10GbE SFP+'

value='Ethernet Converged Network Adapter X710'

Q from the peanut gallery: aside from a blue hedgehog that drops coins everyhwhere, what is sonic?

sonic.com. ISP that is offering 10G residential fiber

a drive-in fast food chain? :)

that too

oh man, I haven't had a sonic chicken fried steak in decades.

Kind of miss that badness.

sommerfeld, ok, I am jelous.

the co-op only goes to 5gb right now, but i wouldn't be surprised if they up it in the future

though I just have 1gb right now because i haven't found a need for anything faster (yet)

Ooops, wrong command: `prtconf -d | grep X7` ==> my bad.

pci8086,0 (pciex8086,1572) [Intel Corporation Ethernet Controller X710 for 10GbE SFP+], instance #0

pci8086,0 (pciex8086,1572) [Intel Corporation Ethernet Controller X710 for 10GbE SFP+], instance #1

Okay, thanks.

jbk, I don't even need 1G but I *want* it. :)

and it's less than half the cost of what i was paying for comcast at my apartment too

granted no tv service, but i was down to like 2-3 channels at most, and I can always do OTA for stuff I don't want to stream

My options are Century Link or comcrap. I refuse to do business with comcrap so here I am. 1G fiber is the fastest they offer.

at least I have a static IP.

i got lucky -- the front half of the neighborhood is serviced by a company with the suitably generic 80s conglomerate sounding 'Consolidated Communications' which apparently is fairly terrible

but the back half is in another county, so it's power is from a local co-op, who also provides fiber internet to their service area

(I could still get consolidated as well if i wanted to, but given their reputation, unless I like really wanted to have redundant links, not sure it's worth it)

unfortunately, they don't do IPv6 yet is i guess one downside

but no cgnat, so....

anyhow I can't seem to force the X710 link to 2.5G or 5G from the illumos end.

jbk, I'm using he.net for an IPv6 tunnel. It works fine as long as my IPv4 connection is stable. pfSense does a good job of connecting to it.

Is there a protocol on dev-guide submissions?

used to just be a PR

There IS a PR. One reviewer, but unsure if we needed more or not.

oh, if you want two for completeness gimme a link

illumos/dev-guide #54 And the reviewer isn't +1-ing yet but I did fix his one concern.
