Hello!
Sorry for the late report, being 5.10-rc7 is out, but current git
kernel (git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git)
is broken with the networking. It affects my openvpn tunnel and even
internet networking.
ping to a local ethernet network (i.e. gateway ping) works, but i
cannot download files from the internet.
openvpn tunnel does not work.
bisected kernel to the following commit:
linux-2.6$ git bisect good
fdf8bee96f9aeaac4559725c2dfae6e1bd7b7043 is the first bad commit
commit fdf8bee96f9aeaac4559725c2dfae6e1bd7b7043
Author: Al Viro <viro@xxxxxxxxxxxxxxxxxx>
Date: Sun Jul 19 18:31:07 2020 -0400
sparc64: propagate the calling convention changes down to
__csum_partial_copy_...()
... and rename them into csum_and_copy_...() - the wrappers become
pointless.
[braino fixed]
