Subject: bpfilter: write fail messages with 5.15.x and centos 7.9.2009
Hello,
I just upgraded the kernel from 5.10.x to 5.15.12 on an old Centos
7.9.2009 server. The kernel is build on a new fedora 35 system
via 'make binrpm-pkg'. With this I see the following errors:
[ 232.140766] bpfilter: Loaded bpfilter_umh pid 6327
[ 232.152144] bpfilter: write fail -32
[ 232.187175] bpfilter: Loaded bpfilter_umh pid 6330
[ 232.198540] bpfilter: write fail -32
[ 232.234604] bpfilter: Loaded bpfilter_umh pid 6332
[ 232.245916] bpfilter: write fail -32
[ 232.281883] bpfilter: Loaded bpfilter_umh pid 6337
[ 232.293222] bpfilter: write fail -32
[ 232.335798] bpfilter: Loaded bpfilter_umh pid 6380
[ 232.347157] bpfilter: write fail -32
[ 244.411821] bpfilter: Loaded bpfilter_umh pid 6712
[ 244.423216] bpfilter: write fail -32
These appear as soon as something is done via iptables (setting
something or just viewing). Is this something I need to worry
about? Under 5.10.81 I did not see these messages.
In Jul 2020 I see a similar report 'bpfilter logging write errors in
dmesg', but could not find a solution.
Any hint what I can do to fix this?
Thanks,
Holger
