Problem: The sys-msg-dispather crashes the VM when trying to send
exit signals from the links of the terminating trace port.
If try-lock of the linked process fails, a pending exit is
scheduled and erts_scheduler_data() is then called to find
"my" run queue. But sys-msg-dispatcher is not a scheduler
and has no scheduler data, hence SEGV.
Fix: If not a scheduler and we cannot get process locks,
schedule process in its previous run-queue.

alert records needs to be thrown from
ssl_handshake:premaster_secret/[2/3] so that operations will end up in
the catch clause of the invokation of certify_client_key_exchange/3 in
ssl_connection.erl, and hence terminate gracefully and not continue to try
and calculate the master secret with invalid inputs and crash.

This is how OpenSSH does. The bytes returned will be put on the
user's tty, so it is better with text than a ssh_msg_disconnect

rfc 4253 says in section 8 that:
"Values of 'e' or 'f' that are not in the range [1, p-1] MUST NOT be
sent or accepted by either side. If this condition is violated, the
key exchange fails."
This commit implements the reception check.
|
|
This is to prevent some dos-attac scenarios. The limit is hard-coded.
|
|
If something bad happens and the socket is closed the
call inet:getopts(Socket, [recbuf]) may return {ok, []}. We
want to treat this as a fatal error and terminate gracefully.
The same goes for the case that inet:getopts returns {error, Reason}
that was not handled either.

Many HTTP headers are optional, and it could be desirable for the
server to filter and maybe even alter them without replacing the
mod_* modules that generate/process them. Add new behaviour
httpd_custom_api with default implementation in httpd_custom.erl.
Add behaviour module in 18 as then we can specify optional callbacks.

During code purging and check_process_code, the checking of the binary reference
embedded in the match binary state was omitted for the tracing tests. This would cause
the binary match state to reference deallocated memory.

Commit 4b691d8d made it possible for accepting transport processes to be
started concurrently, and commit 77c1b162 adapted diameter_sctp to this,
but missed that the publication of the listener process in diameter_reg
has to precede the return of its start function. As a result, concurrent
starts could result in multiple listener processes.
|
|
Make anything but a comm_up sctp_assoc_change crash. Make timeouts more
reasonable.
|
|
Previously it was only run over TCP.
Configure a pool of accepting processes since simultaneous connections
are otherwise prone to rejection, as discussed in commit 4b691d8d.
Tweak timeouts to more reasonable values.

To remove a compilation warning with OTP 18.

Value was used as strictly increasing when it's only non-decreasing,
causing testcases to fail.

To see why it's failing on at least one test machine.

The message was regarded as unknown if the answer message in question
set the E-bit and the application dictionary was not the common
dictionary.
|
|
That is, outgoing answer messages received in response to a
handle_request callback having returned {relay, Opts}.
|
|
To clarify what it is that's being computed, which isn't entirely
obvious. No functional change, just renaming.
|
|
As the first step in starting to count outgoing, relayed answer
messages.
|
|
An incoming Diameter message is either a request, an answer to an
outstanding request, or an unexpected answer. The latter weren't
counted, but are now counted on keys of this form:
{pid(), {{unknown, 0}, recv, discarded}}
The form of the second element is similar to those of other counters,
like:
{{relay, 0|1}, send|recv, invalid_error_bit}
Compare this to the key used when counting known answers:
{{ApplicationId, CommandCode, 0}, recv}
The application id and command code aren't included so as not to count
on arbitrary keys, a topic last visited in commit 49e8b11c.
