Hi,
here are just some random cleanups/fixes for things I've noticed while having a look at https://www.open-mesh.org/issues/298.
batctl: tcpdump: Reset socket state on initialization error batctl: tcpdump: Free resources on SIG(TERM|INT) batctl: ping: Use sig_atomic_t variable to stop ping batctl: Simplify standard error messages with perror
Kind regards, Sven
