Subject: [PATCH] Add bounds-checking to vct_iscrlf and vct_skipcrlf
The macros vct_iscrlf() and vct_skipcrlf() may look at one or two bytes
after its pointer value, causing OOB reads. This would allow
http1_dissect_hdrs to wrongly see a CRLF when one wasn't there (the last
LF left over in the bufer from the previous request).
Change the macros to inline functions, and harden them by always sending
the end pointer so that they can't overflow.
vct_iscrlf() will return an int value of 0 for no [CR]LF, 1 for LF and 2
for CRLF.
vct_skipcrlf() will return the pointer having been skipped 0, 1 or 2
bytes.

Subject: [PATCH] Fix http1_splitline parsing of 2 field HTTP proto lines using
NLNL
When parsing a request like this, "GET /\n\n", the first NL would be
overwritten by nul guard inserted after the 2nd field, and the second NL
would be overwritten by the nul guard after the missing 3rd field. This
would cause http1_dissect_hdrs to attempt to decode the body as headers.

Subject: [PATCH] Do not set the proto txt.b value when third field is missing
In http1_splitline, if the third field is missing, we would still set the
txt.b value to where the field would have been, with a NULL txt.e
entry. This would cause http_Proto to attempt to parse the values
there. Fix this by only setting the .b and .e if the third field was
present.

Subject: [PATCH] Be stricter on final [CR]LF parsing in http1_dissect_hdrs
The end of http1_dissect_hdrs ends with skipping over the final [CR]LF
that marks then end of the headers. Currently that skip is optional, that
is, it is skipped if it was present.
This patch adds an assert if the final [CR]LF is not found when finishing
the parsing. HTTP1_Complete guarantees that it is there, if not we would
not have started parsing the request or response in the first place, and
if it is missing, there must be an error in the parsing leading up to it.

Subject: [PATCH] Fix HTTP header line continuation in http1_dissect_hdrs
When clearing the [CR]LF in a line continuation, we would continue
replacing any [CR|LF|HT|SP] characters up until the end of the buffer,
possibly overwriting later [CR]LFs. Fix this by only unconditionally
overwrite one [CR]LF, and then only replace [HT|SP] with SP to keep with
previous behaviour.
Update r00494.vtc to include multiple line continuations to make sure they
are parsed.
