Not setting net/ipv4/conf/all/rp_filter (explicit setting exists)...

[Neal Becker]

With today's updates I saw these messages:

Not setting net/ipv4/conf/all/rp_filter (explicit setting exists).
Not setting net/ipv4/conf/default/rp_filter (explicit setting exists).
Not setting net/ipv4/conf/all/accept_source_route (explicit setting exists).
Not setting net/ipv4/conf/default/accept_source_route (explicit setting
exists).
Not setting net/ipv4/conf/all/promote_secondaries (explicit setting exists).
Not setting net/ipv4/conf/default/promote_secondaries (explicit setting
exists).

Should I care?

Thanks,
Neal

I've been getting those for a while and ignoring them.
I figure if something stops working right, I might
remember that I saw them and investigate :-).

Nothing has stopped working yet.

I just got these messages. From an ArchLinux thread, these aren't files, they are
kernel configuration parameters, see sysctl.d(5).  "systemd-sysctl.service(8) reads
configuration files ... to configure sysctl(8) kernel parameters." These ones are
settings under /proc/sys/net/ipv4

The files /etc/sysctl.d/50-libreswan.conf and  /usr/lib/sysctl.d/50-default.conf specify
these parameters. Maybe systemd-sysctl.service has default settings for these and it warns
when configuration files override them when it parses these files during certain updates.
Both files are provided by Fedora packages, systemd "System and Service Manager"
and libreswan "IKE implementation for IPsec with IKEv1 and IKEv2 support"
respectively.

So, I don't think you need to worry.

You are answering a query from  November 12, 2020.  You are doing it from HyperKitty and
