BUG: KFENCE: use-after-free read in ipt_do_t ...:

Good day,

After updating to the latest version (IPFire 2.27 (x86_64) - Core Update 162), I have now started to receive the following error in the Log Summary shown below. Any help in trouble shooting/resolving this error is welcomed.

This looks like a bug in the kernel driver for one of your NICs.

This will hopefully be fixed with one of the future kernels.

Thank you for the reply. From this info, can we tell which NIC is having the problem?

  1. NetXtreme II BCM5709 Gigabit Ethernet
  2. Intel 82574L Gigabit Ethernet
  3. Intel 82579 PHY Gigabit Ethernet

I’m currently using only the NetXtreme II.

Thank you,

Just to add to the “fire” I just today saw the same kind of errors in my kernel log. Haven’t been there before, and I upgraded to 162 at least two weeks ago I think. It’s late here so I will dig into this more tomorrow.

01:39:53 kernel:  BUG: KFENCE: use-after-free read in ipt_do_table+0x17f/0x730
01:39:53 kernel:  ==================================================================

Found an explanation: https://www.reddit.com/r/archlinux/comments/prkwa9/comment/hdkdlmy/?utm_source=share&utm_medium=web2x&context=3

I’m now seeing this with Core 167 Testing on a Dell R420 server with built-in Broadcom NICs being used as a firewall. Broadcom NICs are notorious for driver issues so it may be time to add an Intel NIC and disable the Broadcom’s.

Hi,

thank you for reporting back on this issue.

Bad to see kernel updates apparently introducing it on more hardware, not less…

A few days ago, the kernel in Core Update 167 was updated again to 5.15.35, which came with some important stability fixes, especially related to popular NICs. If its not too much of a hassle for you, it would be great if you could give the very latest state of Core Update 167 a try on your hardware, and report if that changes anything.

Thanks, and best regards,
Peter Müller

Good day to all,

I have downloaded and installed the test branch and will provide an update in a few days.

Thank you @pmueller for the reply and feedback.

The updated 5.15.35 kernel has completely resolved my issue. No more kernel error messages have been logged since installing the updated kernel.

Best regards,

Hi,

thank you very much for reporting back! Glad to see this issue has been solved by the kernel update.

Looking forward to the release of Core Update 167 then… :slight_smile:

Thanks, and best regards,

Still getting errors:

Hi,

Fresh install of 169/170 testing gives me these on my new hardware, about 3600/day. No noticeable issues.
