Integral/floating-point division/modulo by zero in C++ is undefined
behavior, so to prevent such cases in a script from crashing Bro,
they're now reported as an error (with script location information) and
the event handler in which it occurred returns immediately.
* origin/topic/bernhard/hyperloglog: (32 commits)
add clustered leak test for hll. No issues.
make gcc happy
(hopefully) fix refcounting problem in hll/bloom-filter opaque vals. Thanks Robin.
re-use same hash class for all add operations
get hll ready for merging
and forgot a file...
adapt to new structure
fix opaqueval-related memleak.
make it compile on case-sensitive file systems and fix warnings
make error rate configureable
add persistence test not using predetermined random seeds.
update cluster test to also use hll
persistence really works.
well, with this commit synchronizing the data structure should work.. ...if we had consistent hashing.
and also serialize the other things we need
ok, this bug was hard to find.
serialization compiles.
change plugin after feedback of seth
Forgot a file. Again. Like always. Basically.
do away with old file.
...
Thanks to git this merge was less troublesome that I was afraid it
would be. Not all tests pass yet though (and file hashes have changed
unfortunately).

- FileAnalysis::Info is now just a record used for logging, the fa_file
record type is defined in init-bare.bro as the analogue to a
connection record.
- Starting to transfer policy hook triggers and analyzer results to
events.
All tests pass with one exception: some Broxygen tests are broken
because dpd_config doesn't exist anymore. Need to update the mechanism
for auto-documenting well-known ports.
Closes#946.
* origin/topic/jsiwek/ticket946:
Fix memory leaks resulting from 'when' and 'return when' statements.
Fix three bugs with 'when' and 'return when' statements. Addresses #946
Added a generic gtpv1_message event generated for any GTP message type.
Added specific events for the create/update/delete PDP context
request/response messages.
Addresses #934.
Case blocks in switch statements now must end in a break, return, or
fallthrough statement to give best mix of safety, readability, and
flexibility.
The new fallthrough keyword explicitly allows control to be passed to the
next case block in a switch statement.
Addresses #754.
Case bodies now don't require a "break" statement to prevent fallthrough
to case bodies below. Empty case bodies generate an error message at
parse-time to help indicate the absence of automatic fallthrough; to
associate multiple values with a case, use "case 1, 2:" instead of
"case 1: case 2:".
The index expression can take up to two indices for the start and end
index of the substring to return (e.g. "mystring[1,3]"). Negative
indices are allowed, with -1 representing the last character in the
string. The indexing is not cyclic -- if the starting index is >= the
length of the string an empty string is returned, and if the ending
index is >= the length of the string then it's interpreted as the last
index of the string. Assigning to substrings accessed like this isn't
allowed.
They behave like C-style switches except case labels can be comprised
of multiple literal constants delimited by commas. Only atomic types
are allowed for now. Case label bodies that don't execute a "return"
or "break" statement will fall through to subsequent cases. A default
case label is allowed.
That field is based on TCP sequence numbers and on seeing a SYN followed
by a failed RST injection response, the initial sequence number tracked
the value in the injection (most likely zero) instead of value in
subsequent SYN response. This could make c$resp$size be set to large
values when it's not really.
Also removed some dead code paths.
* origin/topic/jsiwek/hook:
Change hook calls to only be allowed when preceded by "hook" keyword.
Clarification in hook documentation.
Hook functions now directly callable instead of w/ "hook" statements.
Closes#918.
The return value of the call is an implicit boolean value of T if all
hook handlers ran, or F if one hook handler exited as a result of a
break statement and potentially prevented other handlers from running.
Scripts don't need to declare hooks with an explicit return type of bool
(internally, that's assumed), and any values given to (optional) return
statements in handler definitions are just ignored.
Addresses #918.
