p54usb module in linux-modules-extra-5.0.0-23-generic does not work

[Dee Raj]

== SRU Justification ==
User report that the p54usb driver will crash when trying to load it on 5.0 kernel for a Dell Wireless 1450 Dual-band (802.11a/b/g) USB 2.0 adapter. This was caused by commit e3554197 (p54: Use skb_peek_tail() instead of direct head pointer accesses.)

== Fix ==
* 1645ab93 (p54: fix crash during initialization)

This patch added a check for target_skb to determine where to queue the buffer. It can be cherry-picked into Disco.
Eoan got this patch from v5.2.1 upstream stable release update.

== Test ==
Test kernel could be found here:
https://people.canonical.com/~phlin/kernel/lp-1839693-p54usb/

This issue was reported against Bionic HWE 5.0 kernel, user confirmed that the patched B-hwe kernel can fix this issue.

== Regression Potential ==
Low, change limited to p54usb driver, patch tested with positive test result.

== Original Bug Report ==

I am using the Product: Dell Wireless 1450 Dual-band (802.11a/b/g) USB 2.0 Adapter

This relies on the p54usb driver. It works great on kernel 4.18. I upgraded to 5.0.0-3 and the device fails to start.

On the older kernel, things seem good:

Hello, can you give this B-hwe kernel a try:
https://people.canonical.com/~phlin/kernel/lp-1839693-p54usb/B-hwe/

Thanks

[Dee Raj (deker0)]

 Hi there, sure I’m happy to try it. But I am a bit of a newbie, so I need exact steps on how to install this kernel and even better perhaps a screen share or some other way to communicate with someone while I am doing it. Thank you.

Hi,
Please:
1. Create a new directory in your file browser
2. Download all the *.deb file in the link, put them into that new directory.
3. In that directory, right click (not on files, but anywhere else) will show you an option "Open in Terminal"
4. In the newly opened terminal, execute the following command: "sudo dpkg -i *.deb"
5. After it's done, reboot and see if the p52usb module works for you or not.

This test kernel installed on your system will be removed in the future during the upgrade process.

Thanks

[Dee Raj (deker0)]

 Thank you so much for the detailed steps. I will try this tonight and let you know if the USB wifi card starts working again.

Hi,
thanks for the test, I will SRU this so people can get this fix from updates.

[Dee Raj (deker0)]

 Hi there, I hope all is well. I wanted to let you know that something odd keeps happening now with the updated packages you sent me.
After about one week of use, the USB card stopped working. I thought maybe I had run some software update and overwrite your files. So, I ran the command you gave me ("sudo dpkg -i *.deb") and restored the packages you sent.
After another week, the same thing happened again - this time I am positive that I did not run any software updates and yet the USB card once again stopped working. I again ran "sudo dpkg -i *.deb" and restored your files and rebooted. It started working same as normal.
So, I decided to write to you and let you know this. I have no idea why it's happening, but two times cannot be a fluke.

Thanks, D E K E R

Hi,
this temporary deb package will be replaced by the one in the updates.

So yes, running a dist-upgrade command to install a newer kernel will overwrite it.
And even if you try to install it again, if you didn't select to boot with this kernel you will be still using the latest kernel in the update.

The latest kernel will have this issue as this patch haven't land in our kernel tree yet, please follow this bug with the bug status (still in "in-progress" for Disco 5.0 kernel), this would probably land in the next sru-cycle.
Thanks.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Dee Raj (deker0)]

 If further testing is needed, send me the updated kernel files and I’ll install on my PC and test.

results. If the problem is solved, change the tag 'verification-needed-
disco' to 'verification-done-disco'. If the problem still exists, change
the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  p54usb module in linux-modules-extra-5.0.0-23-generic does not work

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Disco:
  Fix Committed
Status in linux source package in Eoan:
  Fix Released

Bug description:
  == SRU Justification ==
  User report that the p54usb driver will crash when trying to load it on 5.0 kernel for a Dell Wireless 1450 Dual-band (802.11a/b/g) USB 2.0 adapter. This was caused by commit e3554197 (p54: Use skb_peek_tail() instead of direct head pointer accesses.)

  == Fix ==
  * 1645ab93 (p54: fix crash during initialization)

  This patch added a check for target_skb to determine where to queue the buffer. It can be cherry-picked into Disco.
  Eoan got this patch from v5.2.1 upstream stable release update.

  == Test ==
  Test kernel could be found here:
  https://people.canonical.com/~phlin/kernel/lp-1839693-p54usb/

  This issue was reported against Bionic HWE 5.0 kernel, user confirmed
  that the patched B-hwe kernel can fix this issue.

  == Regression Potential ==
  Low, change limited to p54usb driver, patch tested with positive test result.

  == Original Bug Report ==

  I am using the Product: Dell Wireless 1450 Dual-band (802.11a/b/g) USB
  2.0 Adapter

  This relies on the p54usb driver. It works great on kernel 4.18. I
  upgraded to 5.0.0-3 and the device fails to start.

  On the older kernel, things seem good:
