I'm getting a kernel panic on the >=4.14.71 stable kernels, and I've
isolated the problem back to this patch.
My 4.18.11 kernel seems to be OK.
Whenever I inject a delay into the interface with iproute2 tools, I get a panic.
Example command:
tc qdisc add dev eth0 root netem delay 35ms
The RIP is pointing at netif_skb_features+0x31/0x230
My efforts to get a transmittable copy of the panic have been thwarted.
There's some confusion between this patch and the upstream patch
refered to in the commit message
The upstream commit patches net/sched/sch_netem.c which isn't even
touched in this commit.
Althought the commit messages are the same, the two patches seem to
have a different purpose.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/sched?id=bffa72cf7f9df842f0016ba03586039296b4caaf
The commit message seems more relavant to this patch.
The upstream commit bffa72cf7f9df842f0016ba03586039296b4caaf has not
yet been applied to the stable tree.
I decided to roll the dice, and apply the upstream patch
bffa72cf7f9df842f0016ba03586039296b4caaf (it's been in the main kernel
tree just over a year).
When I manually patch my 4.14.74 kernel with
bffa72cf7f9df842f0016ba03586039296b4caaf, my panic seems to be solved.
I'm uncertain if this is the proper solution, but I hope this points
in the direction of the issue.
