Building the BPF selftests with clang 11, I'm getting the following
error:
CLNG-LLC [test_maps] profiler1.o

The requirement to build resolve_btfids whenever CONFIG_DEBUG_INFO_BTF
is enabled breaks some cross builds. For example, when building a 64-bit
powerpc kernel on amd64 I get:
Auto-detecting system features:
...libelf: [ [32mon[m ]
... zlib: [ [3
The tests in lib/test_bpf.c were all passing in 5.4 when using the JIT,
but some are failing in 5.7/5.8. Some of the failures are due to the
removal of BPF_SIZE_MAX causing some expected failures to pass, which I
have already send a patch for [1]. The remaining failures appear to be
regressions. I
should no longer be flagged.

We got a bug report against Ubuntu about networking failing to come up
in the Oracle cloud:

This is with a kernel based on 4.18.5, and it has also been seen with a
4.17-based kernel. I'm not currently aware of any working kernel
version. The driver seems to
sting, would appreciate reports reports of

This fixes the issue for me, downloads are faster and rx_length_errors
does not show any errors.

I'm seeing a performance regression with virtio_net that looks to have
started in 4.12-rc1. I only see it in one context though, downloading
snap packages from the Ubuntu snap store. For example:
https://api.snapcraft.io/api/v1/snaps/download/b8X2psL1ryVrPt5WEmpYiqfr5emixTd7_1797.snap
