These display bases work to replace unprintable characters so the
name is a misnomer. In addition they are the same option and this
display behaviour is not something that is configurable.
This does not affect encodings because all our internal text strings
need to be valid UTF-8 and the source encoding is specified using
ENC_*.
Remove the assertion for valid UTF-8 in proto.c because
tvb_get_*_string() must return a valid UTF-8 string, always, and we
don't need to assert that, it is expensive.
Starting with 3.0 there is a new non backwards compatible Web-Sec-Protocol for BLIP, so the plugin should handle both (the differences are irrelevant from Wireshark's standpoint)
Until now, mistakenly, the buffer for decompressing compressed BLIP messages
has been statically allocated as 16 Kb, but that is not valid behavior.
16 Kb is the maximum size of a _compressed_ frame. In theory, due to the
ability to zipbomb, there is virtually no upper bound on what the maximum
size of an uncompressed frame could be. However, to keep sanity, it has
been made into a preference with a reasonable default that is not likely to
be exceeded (64 Kb). The behavior before for this was that wireshark would
crash because the dissector would return NULL for a decompressed buffer due
to error and then try to deference it later. A null check has been added,
so that the behavior is now that the packet will show
'<Error decompressing message>' instead, and log why it couldn't handle the
compressed message. Closes#16866.
Due to the way the BLIP compresses its messages, it quickly falls apart
when the messages are not examined exactly in order (as is the case
when selecting random frames inside of a capture). The only solution
I can see is to only decompress once and store the result somewhere
that is persistent at the file level.
