The "asn1" target rebuilds all asn1 dissectors. Alternatively to rebuild a specific one, use a target such as "generate_dissector-pkcs1". Example: mkdir build cd build cmake .. cmake --build . --target generate_dissector-pkcs1 Or if you use ninja: mkdir build cd build

Hi, Yes it's related to that bug. And if memory serves the trace would illustrate the problem. I don't see how the compression/decompression could recover as in showing the missing header element. I'm not sure I understand what your objection is. Is it in how to present the non decodable element

2020-05-15 Thread Mikael Kanstrup
Hi, Fast BSS Transitioning decryption is unfortunately not supported by Wireshark. Wireshark uses passphrase/PSK/PMK together with 4-way handshake to derive PTK and GTK. FT key hierarchy and key derivation is not handled by the decryption engine so PTK remains unknown which makes decryption fail.
