Re: Wpa test failure

["Maynard, Christopher" <Christopher.Maynard () IGT com>]

Is there a problem with the environment perhaps?

On Windows, I needed to set WIRESHARK_APPDATA to the location of the 80211_keys file in order for this to work.

Maybe HOME isn’t enough?  Do you have to set WIRESHARK_DATA_DIR and/or WIRESHARK_RUN_FROM_BUILD_DIRECTORY?  I was 
unsuccessful attempting this with a recent 2.6.0 build on a RHEL7 system as I was unable to get past this error once 
WIRESHARK_DATA_DIR was set:

ERROR:privileges.c:153:started_with_special_privs: assertion failed: (init_process_policies_called)

… which I find odd because tshark was running from the build directory as a normal user, and anyway, tshark is only 
reading a file, not capturing, so why should it care about special privileges anyway?

Subject: [Wireshark-dev] Wpa test failure

I'm playing with the test suite (make test-programs && make test). I hit a test that doesn't pass on ubuntu 14.04, but 
passes on 16.04. The test is test_80211_wpa_tdls

This puzzles me a lot and I'd like to have some clues if someone has any. Basically the problems seems that the wpa 
keys are not properly loaded on 14.04.

Reproducer:
mkdir -p /tmp/fakehome/.config/wireshark/
cp test/config/80211_keys.tmpl /tmp/fakehome/.config/wireshark/80211_keys
HOME=/tmp/fakehome/ ./build/run/tshark -o 'wlan.enable_decryption: TRUE' -r test/captures/wpa-test-decode-tdls.pcap.gz 
-Y icmp

The test checks the output for 2 matching lines. On 14.04 the above command doesn't print anything, because nothing 
gets decrypted. On 16.04 it outputs 2 icmp lines.
Any idea?
Dario.
