Wireless, Wi-Fi, rum(4), urtw(4): no wlan0 unless the savecache service is deleted from the shutdown runlevel before the start of the computer

grahamperrin commented 7 years ago

Whilst troubleshooting a different issue involving shutdown, I experimented with deletion of the savecache service.

Without that service at the shutdown runlevel, it seemed easier to make reliable use, with TrueOS Desktop, of a USB network adapter that is supported as a wireless network interface by FreeBSD 12.0-CURRENT.

Today I performed more focused testing. From the attached file:

In the first twenty-something cases, without savecache, a login to a desktop environment found an icon for wlan0.

The reboot at 14:13:46 was preceded by experimental reintroduction of the savecache service. Critically:

the subsequent boot at 14:15:02 did not have wlan0.

The reboot at 14:16:06 was preceded by deletion of the savecache service and I'm now using the device at wlan0 without difficulty.

Hmm, sorry, where (if anywhere) should I find rum0 in the file system?

I imagined that as a device, it should be at /dev/, hence the change of title here after performing a further test with the service added before a restart of the OS:

I think I may be seeing this regression as well but with a usb ethernet ums0. I will try removing savecache from shutdown to see if this fixes.

pkgdemon commented 7 years ago

Ok removing savecore doesn't fix my issue. My issue was just the fact that devd is no longer loading the module. @grahamperrin I don't believe wireless devices ever show in in /dev, or that anything is created in the filesystem for network devices. I know sysctl -b net.wlan.devices can be used to see wireless devices if they have a module loaded. Otherwise pciconf -lv may be of some use just to see if the hardware is detected at all even without a module loaded.

For consideration: D-Link DWL-G122 rev C1 now recognised (wlan0) at a MacBookPro8,2

… not recommended, known to cause trouble, but for the moment I'm most interested in Internet connectivity. …

pkgdemon commented 7 years ago

Does the exstension cable include a hub as well?

grahamperrin commented 7 years ago

No, just a simple cable. Maybe one metre long. White. No manufacturer's brand but it's well-manufactured.

MacBookPro5,2

https://discourse.trueos.org/t/wireless-networking-with-rum-4-and-a-d-link-device-for-wlan0/459/6?u=grahamperrin reminds me that around 2016-12-27 (four days ago) I had this Mac working with a non-encrypted installation of TrueOS Desktop on a USB flash drive.

A few hours ago I overwrote that with with an encrypted installation, updated to FreeBSD 12.0-CURRENT #12 5ef9376(drm-next-4.7): Thu Dec 29 16:26:36 UTC 2016 root@gauntlet:/usr/obj/usr/src/sys/GENERIC, booted five or six times with required lines in /etc/rc.conf:

none of the boots resulted in wlan0.

I deleted savecache from runlevel shutdown, commanded shutdown -r now and now:

wlan0 is present and working.

(Stage two of an update routine began a couple of minutes ago, I guess that it'll be 5ef9376 again with changes in some areas.)

pkgdemon commented 7 years ago

Does encrypted vs non encrypted make the difference? Or is it running TrueOS from a USB flash drive vs internal drive?

pkgdemon commented 7 years ago

Or is it the cable? Need more clarity on this one.

grahamperrin commented 7 years ago

One memorable difference: tl;dr the earlier, non-encrypted installation was fresh when the USB flash drive was at an HP desktop. I made that an opportunity to subsequently learn, re-learn how to manually add support when moving an installation from one hardware environment to another. Point of reference https://discourse.trueos.org/t/macbookpro5-2-17-macbook-pro-2009/479 but I'm carefully not quoting from that opening post; most relevant to this issue is:

at some point during that learning experience, I probably did quietly, routinely delete the savecache service, for the D-Link to be usable in that environment.

Relevant from the second post in that topic:

I performed a fresh, encrypted installation to the same USB flash drive, this time with the drive connected to the MacBookPro5,2. …

The D-Link device almost certainly was not present at that time of freshness. That's almost certain because:

this Mac's three ports are in close proximity to each other
the USB flash drive that contained the installer is a Kingston DataTraveler G3, the physical size of which prevents use of any adjacent port
with the middle port inaccessible, the USB flash drive that received the installation (Kingston DataTraveler G4, 16 GB) was at the third port.

That's potentially a lot to take in :-) so if anything remains unclear, just say.

Next steps

On one hand

I might try this USB flash drive with the D-Link device at something other than an Apple notebook; tell whether the run of savecache can be troublesome with another brand of computer. If I do this, I'll probably target an old (c. 2007) but predictable Ergo Vista 621.

On the other hand

Should I defer broader testing until after the 'new' FreeBSD netif flavour of OpenRC network service is in the mix?

(https://gitter.im/trueos/troubleshooting?at=5867e1dcd99b1dd03d2e7c74 there's a question about distinguishing between flavours of the service.)

Thanks

pkgdemon commented 7 years ago

Yeah this is way too much information to take in. I only need to know the answers to the specific questions I asked above. Does that require retesting on your end? Or can you just narrow down what you are able to without a reinstall if that is the case? Namely is it the usb extension cable to start?

grahamperrin commented 7 years ago

Where the extension cable was required, I'd like to retest to be certain however: if I do so without knowing whether it's the new or old flavour of network service, I'll become confused.

Results from today's test with the MacBookPro5,2, which does not require an extension cable, seem reasonably conclusive.

pkgdemon commented 7 years ago

Closing for now due to lack of required information to reproduce.

grahamperrin commented 7 years ago

MacBookPro5,2 + D-Link DWL-G122 rev C1 + encrypted TrueOS Desktop booting from a USB flash drive without savecache service at runlevel shutdown:

very many successes, enough for me to treat savecache as an offending service.

This morning I reintroduced the offending service to that USB flash drive and as I expected:

all subsequent boots (at least five, the last three of which were with, without then with atp(4)) failed to gain the wlan0 interface for the D-Link.

I shutdown the MacBookPro5,2, removed both USB devices and introduced them – and the offending service – to a different computer …

HP EliteBook 8540p with the USB flash drive in its left port, D-Link in the rearmost of its right ports:

EFI blind mode and I did not get (or did not wait long enough for) the display manager, so I pressed the ACPI power button to shut down the OS.

On to a different computer …

Ergo Vista 621 with the USB flash drive in a port at the rear (the left, viewed from the front), D-link in the rearmost of its right ports:

the flash drive was not found so I retried with a swap of positions (flash drive in the rearmost of its right ports) but still it was not found so I pressed the ACPI power button to stop the computer.

On to a different computer …

MacBookPro11,2 with the USB flash drive to the left, D-Link to the right:

failed to gain the wlan0 interface for the D-Link.

So I deleted the offending service, restarted the OS:

success; there's wlan0, associated with my preferred network and good for Internet service.

Issue and workaround reproduced with the D-Link device connected to a Samsung NF110 netbook.

Observation

Whilst there's no wlan0, there is a periodic flash from the Lnk indicator of the D-Link device.

The same was probably observable with the device at the Mac notebooks.

pkgdemon commented 7 years ago

Looks like that is kldstat before? What does kldstat look like after?

grahamperrin commented 7 years ago

Truly, those were the before and after.

Before the problem, without the service:

Mon  2 Jan 2017 18:29:02 GMT
 6:29p.m.  up 1 min, 1 users, load averages: 1.66, 0.58, 0.22

Still before the problem:

$ sudo rc-update add savecache shutdown
Password:
 * service savecache added to runlevel shutdown
$

Then the restart (… run of savecache … start).

After that restart, with the problem:

Mon  2 Jan 2017 18:33:39 GMT
 6:33p.m.  up 2 mins, 1 users, load averages: 1.52, 0.55, 0.21

https://discourse.trueos.org/t/trueos-desktop-2016-12-27-x64-and-ipv4-lan-with-dhcp/595/11:

… With TrueOS from 10/28/2016, wlan (D-Link, USB) worked "out of the box". But every update since then killed it.

I decided to do a fresh install with 12/27/2016 (the latest). Result: no wlan. …

pkgdemon commented 7 years ago

I encountered this with another user with built in wireless at the office using if_run. Adding the kernel module to modules fixes. The issue seems to be devd starting after networking and loading the kernel module after network. In your case you could try adding if_rum to /etc/conf.d/modules to see if that resolves it without the removal of savecache as well.

grahamperrin commented 7 years ago

Thanks. rum(4) tests progressing at a MacBookPro11,2

For the @Mystified1234 case, urtw(4) and I guess that /etc/conf.d/modules should include if_urtw

grahamperrin commented 7 years ago

Tested successfully at the MacBookPro11,2:

restarts
power on after ACPI shutdown

– with both atp and if_rum in /etc/conf.d/modules

pkgdemon commented 7 years ago

Yeah. For now I am going to add these into our stock modules file. It is what we have always done in PC-BSD anyway. When we have devd working properly I can revert.

pkgdemon commented 7 years ago

Fixed will be in next unstable push after packages build. https://github.com/trueos/trueos-core/commit/d0da1659cbaf9b940f77b3932ef299fb74189d23

grahamperrin commented 7 years ago

Should we also add urtw for the case at https://github.com/trueos/trueos-core/issues/252#issuecomment-272576638 above?

(Maybe overlooked, the light grey of the quoted text.)

pkgdemon commented 7 years ago

Ah. I overlooked this or may have mixed the tickets up. Will reopen until i get it added, and pushed.
