Subject: [PATCH] Lookup dumpcap in PATH
|
|
|
|
NixOS patch: Look for dumpcap in PATH first, because there may be a
|
|
dumpcap wrapper that we want to use instead of the default
|
|
non-setuid dumpcap binary.
|
|
|
|
Also change execv() to execvp() because we've set argv[0] to "dumpcap"
|
|
and have to enable PATH lookup. Wireshark is not a setuid program, so
|
|
looking in PATH is not a security issue.
