For some outgoing messages (not response) the following
error(s) has been corrected:
* encrypted: logged incorrectly, should have written the v3-header
and the scoped pdu, but was actually logged as-is (encrypted),
making conversion impossible.
* un-encrypted: messages was not logged at all.

If conversion of an Audit Trail Log (ATL) entry failed,
this could result in an abort of the entire conversion,
not just the one entry. This has now been improved so
that the failure now results in a "error message" into
the "stream". Furthermore, we now keep track of the number
of entries we succeede and fail to convert.

ERL-724: "During a 'gentle' shutdown, supervisors unlink from their
children before sending shutdown signals to them. This can lead to a
race condition in supervision trees, when the timeout for gentle
shutdown of a parent supervisor expires and it kills a child
supervisor that has just unlinked from a child of its own, leaving the
child supervisor's own child still running after its supervisor is
killed."
This commit adds a warning about this in the documentation.

Implement socket options recvtclass, recvtos, recvttl and pktoptions.
Document the implemented socket options, new types and message formats.
The options recvtclass, recvtos and recvttl are boolean options that
when activated (true) for a socket will cause ancillary data to be
received through recvmsg(). That is for packet oriented sockets
(UDP and SCTP).
The required options for this feature were recvtclass and recvtos,
and recvttl was only added to test that the ancillary data parsing
handled multiple data items in one message correctly.
These options does not work on Windows since ancillary data
is not handled by the Winsock2 API.
For stream sockets (TCP) there is no clear connection between
a received packet and what is returned when reading data from
the socket, so recvmsg() is not useful. It is possible to get
the same ancillary data through a getsockopt() call with
the IPv6 socket option IPV6_PKTOPTIONS, on Linux named
IPV6_2292PKTOPTIONS after the now obsoleted RFC where it originated.
(unfortunately RFC 3542 that obsoletes it explicitly undefines
this way to get packet ancillary data from a stream socket)
Linux also has got a way to get packet ancillary data for IPv4
TCP sockets through a getsockopt() call with IP_PKTOPTIONS,
which appears to be Linux specific.
This implementation uses a flag field in the inet_drv.c socket
internal data that records if any setsockopt() call with recvtclass,
recvtos or recvttl (IPV6_RECVTCLASS, IP_RECVTOS or IP_RECVTTL)
has been activated. If so recvmsg() is used instead of recvfrom().
Ancillary data is delivered to the application by a new return
tuple format from gen_udp:recv/2,3 containing a list of
ancillary data tuples [{tclass,TCLASS} | {tos,TOS} | {ttl,TTL}],
as returned by recvmsg(). For a socket in active mode a new
message format, containing the ancillary data list, delivers
the data in the same way.
For gen_sctp the ancillary data is delivered in the same way,
except that the gen_sctp return tuple format already contained
an ancillary data list so there are just more possible elements
when using these socket options. Note that the active mode
message format has got an extra tuple level for the ancillary
data compared to what is now implemented gen_udp.
The gen_sctp active mode format was considered to be the odd one
- now all tuples containing ancillary data are flat,
except for gen_sctp active mode.
Note that testing has not shown that Linux SCTP sockets deliver
any ancillary data for these socket options, so it is probably
not implemented yet. Remains to be seen what FreeBSD does...
For gen_tcp inet:getopts([pktoptions]) will deliver the latest
received ancillary data for any activated socket option recvtclass,
recvtos or recvttl, on platforms where IP_PKTOPTIONS is defined
for an IPv4 socket, or where IPV6_PKTOPTIONS or IPV6_2292PKTOPTIONS
is defined for an IPv6 socket. It will be delivered as a
list of ancillary data items in the same way as for gen_udp
(and gen_sctp).
On some platforms, e.g the BSD:s, when you activate IP_RECVTOS
you get ancillary data tagged IP_RECVTOS with the TOS value,
but on Linux you get ancillary data tagged IP_TOS with the
TOS value. Linux follows the style of RFC 2292, and the BSD:s
use an older notion. For RFC 2292 that defines the IP_PKTOPTIONS
socket option it is more logical to tag the items with the
tag that is the item's, than with the tag that defines that you
want the item. Therefore this implementation translates all
BSD style ancillary data tags to the corresponding Linux style
data tags, so the application will only see the tags 'tclass',
'tos' and 'ttl' on all platforms.

See also https://bugs.erlang.org/browse/ERL-680.
The right associative short circuit expressions 'andalso' and 'orelse'
are expanded by the Compiler (see v3_core) into 'case' expressions. If
parentheses are used to enforce left associativeness, variables are
introduced, and the time needed by Dialyzer increases exponentially.
Rather than trying to fix Dialyzer itself, v3_core now rewrites
repeated use of 'andalso' ('orelse') into right associative
expressions before creating the 'case' expressions.

We want to make sure that the sender process that may get stuck in
prim_inet:send will die if the tls_connection process is
terminated. And we also like to make sure that it terminates as
gracefully as possible. So when the tls_connection process dies it
spawns a killer process that will brutaly kill the sender if it is
unresponsive and does not terminate due to its monitor of the
tls_connetion process triggering.
When the sender process also acts as distribution controller it
may also have other processess that it is linked with that it
should bring down or that could bring the connection down.
|
|
|
|
Separate sending and receiving when using TCP as transport
as prim_inet:send may block which in turn may result
in a deadlock between two Erlang processes communicating over
TLS, this is especially likely to happen when running Erlang distribution
over TLS.

All 1xx (informational), 204 (no content), and 304 (not modified)
responses MUST NOT include a message-body, and thus are always
terminated by the first empty line after the header fields.
This implies that chunked encoding MUST NOT be used for these
status codes.
This commit updates the client to gracefully handle responses from
faulty server implementations that can send chunked encoded 204,
304 or 1xx responses.
