Bug ID: 212317
Summary: /proc/net/dev: reversed counter for network
namespaces?
Product: Networking
Version: 2.5
Kernel Version: 5.10.23
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1

Hello.
Yesterday i extended my tmux status line to include all "network devices", and
now i am looking at a line
RF:W~B~ wlp1s0~158/16 wg0~6/2 browse~8/124
which are /proc/net/dev devices (less in-namespace stuff) with non-0 byte
counts.
wlp1s0 is the sole connection to the internet, and browse is a network
namespace that boxes graphical browser usage, and can only access the internet,
no local services (but DNS).
As you can see it states it has send 124 MiB and receives 8 MiB, which i deem
wrong, especially since the entire up/downstream bytes of wlp1s0 state
something different. Could it be the counts are reversed?
Thank you!!
