Hi,
I can reproduce an RxRPC leaked-peer warning during network namespace
teardown after adding an AFS cell.
Reproducer:
dmesg -C
unshare -n sh -c '
ip link set lo up 2>/dev/null || true
echo "add reprocell 127.0.0.1" > /proc/fs/afs/cells
cat /proc/net/rxrpc/peers
'
sleep 2
dmesg | grep "Leaked peer"
Observed output:
Proto Local Remote Use SST Maxd LastUse RTT RTO
UDP [::]:7001 127.0.0.1:7003 1 128 1440 37s -1 0
[ 37.969040] rxrpc: Leaked peer 61 {1} 127.0.0.1:7003
Tested on:
commit 9fbbf69eab3417732ec2adf93e42e507351dd80a
Linux 7.1.0-13212-g9fbbf69eab34
CONFIG_NET_NS=y
CONFIG_AF_RXRPC=y
CONFIG_AFS_FS=y
Thanks.
