Since logger has now knowledge of the handler specific data ('config'
field in the handler configuration map), it can not merge this data
structure with default or old values upon configuration
change. Instead, the handler callback changing_config must do
this. Earlier, this callback did not reflect if the configuration
change was initiated by a call to set_handler_config or
update_handler_config, so the handler did not know if unspecified
fields should get default values or the values from the existing
configuration.
To overcome this problem, the new parameter SetOrUpdate is added to
this callback. If SetOrUpdate equals set, then default values should
be used. If SetOrUpdate equals update, then existing configuration
values should be used.

Added proper send timeout handling.
Made use of the enif_select(mode = cancel) feature. Each
time a timeout expires, the "active" send (the surrent write
select) has to be cancelled.

Now that variables are represented as #b_var{}, there's no longer
any risk of colliding with anything else.
|
|
We chose to refer to variables through their var_name() because we
anticipated the need to annotate them, but it turned out we didn't
really need that, and many things become a lot cleaner if the
entire #b_var{} is used to represent variables.

* ingela/ERL-622/fix:
ssl: Move link to correct process
|
|
The link should be between the connection process and the tls_sender
process. But the start of the tls_sender process needs to be done
by the process that also starts the connection process in order to
correctly create the opaque #ssl_socket{}.
|
|
Added proper connect and accept timeout handling.
Made use of the enif_select(mode = cancel) feature. Each
time a timeout expires, the previous operation (connect or accept)
has to be cancelled (actually its the select operation that has
to be cancelled). Only partial implementation of cancel for now
(connect and accept). More to follow...

OTP-14461 - New 'rand' algorithm: Xoroshiro928** also for 'crypto'
Implement a new 'rand' algorithm named 'exro928ss' and a new 'crypto' plugin for 'rand' named 'crypto_aes'.
Both are based on Xoroshiro928** which is derived from Xoroshiro1024** modified to use 58-bit words for performance reasons in the Erlang VM. Xoroshiro1024** has got the Xoroshiro1024 generator and the StarStar scrambler from the 2018 paper "Scrambled Linear Pseudorandom Number Generators" by David Blackman and Sebastiano Vigna.
This generator and scrambler combination shows no systematic weaknesses in standard statistical tests as TestU01(BigCrush) and PractRand, unlike the previously used * and + scramblers in the 'rand' module that exhibit statistical weaknesses for the lowest bits.
The 'crypto' plugin uses AES-256 as scrambler and the Xoroshiro928 as generator, which gives the same very long period and jump functions as for Xoroshiro928**, but a cryptographically secure scrambler gives absolutely no detectable statistical weaknesses regardless of how the generated numbers are used.
The speed of 'exro928ss' is only about 30-50% slower than the default fast 'rand' algorithm, but the state is roughly the double and it produces about 8 times the garbage per iteration.
The speed of 'crypto_aes' is about half (amortized) that of the default fast 'rand' algorithm which is fast and thanks to doing encryption in batches caching the result. Hence the state is much larger.

Added some more tests for sendmsg (with cmsghdr).
OTP-14831
|
|
Add more debug printouts for the new sendmsg. Also added
new (erlang) types with doc.
OTP-14831
|
|
Added function sendmsg/2,3,4. Actually worked on the first try.
Something must be wrong...
Still no supported cmsghdr's (only support headers where the
data part is already a binary, which therefor does not require
any processing). So if the cmsghdrs actually work is unclear.
OTP-14831
|
|
Added processing or more cmsg headers (for more options).
Now (also) supports: socket:timestamp.
Also various fixes and cleanups.
For some reason calling getopt(Sock, 0, {13, int}) (or similar)
fails with badarg even though the nif-function (nif_getopt) actually
returns a valid value (for instance: {ok, 0}).
OTP-14831
|
|
Added decoding of the "known" control message options: pktinfo,
recvtos, recvttl and recvorigdstaddr).
OTP-14831
|
|
It seems to work, with atleast some of the cmsg options.
More testing needed...
OTP-14831
|
|
Added support for ip level socket option SENDSRCADDR.
This option requires sendmsg to actually use, so we
cannot test this fully at the moment.
OTP-14831
|
|
Added support for ip level socket option RECVORIGDSTADDR.
This option requires recvmsg to actually use, so we cannot
test this fully at the moment (although both set and get works).
OTP-14831
|
|
Added support for ip level socket option RETOPTS.
OTP-14831
|
|
Added support for ip level socket option TRANSPARENT.
OTP-14831
|
|
Added support for ip level socket option PKTINFO.
This option requires sendmsg and/or recvmsg to actually use,
so we cannot test this fully at the moment (although both set
and get works).
OTP-14831
|
|
Added support for the IPv6 socket option RECVERR.
To actually make use of this option, we need the recvmsg
function, which we don't have yet. Baby steps.

Added support for the IPv6 socket option ROUTER_ALERT.
Only supported for raw sockets.

|
|
Added support for the IPv6 socket option UNICAST_HOPS.
OTP-14831.
|
|
Added support for the IPv6 socket option(s) FLOWINFO.
The option returns with einval when calling setsockopt,
so either you need to be a privileged user to update, or its not
actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with DSTOPTS.
Needs furher checking.

Added support for the IPv6 socket option(s) DSTOPTS.
The option returns with einval when calling setsockopt,
so either you need to be a privileged user to update, or its not
actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with RTHDR and HOPLIMIT.
On FreeBSD, it says that HOPOPTS requires superuser privileges.
Needs furher checking.
OTP-14831.
|
|
Added support for the IPv6 socket option(s) AUTHHDR and HOPOPTS.
Its possible that the option is AUTHHDR is obsolete. It says so in
the include files and when trying to get it (getsockopt) it returns
with enoprotoopt.
The option HOPOPTS returns with einval when calling setsockopt,
so either you need to be a privileged user to update, or its not
actually possible to update this option (even though it says
nothing about that in the man page. It only talks about set).
This is the same behaviour as with RTHDR and HOPLIMIT.
On FreeBSD, it says that HOPOPTS requires superuser privileges.
Needs furher checking.
OTP-14831.
|
|
Added support for the IPv6 socket option RTHDR.
On FreeBSD this option requires superuser privileges to update.
There is no mention of this on linux, but its still not possible
to update (einval), so I assume that its the same there.

Added support for the IPv6 socket option RECVPKTINFO.
This option is called PKTINFO on FreeBSD, so that value
will also be accepted.

|
Added support for the IPv6 socket option MULTICAST_LOOP.
OTP-14831.
|
|
Added support for the IPv6 socket option MULTICAST_IF.
OTP-14831.
|
|
Added support for the IPv6 socket option MULTICAST_HOPS.
OTP-14831.
|
|
Added support for ip level socket option RECVOPTS.
OTP-14831
|
|
Added support for ip level socket option FREEBIND.
Note that there is an option available on FreeBSD called
IP_BINDANY, which seems to have similar properties (FREEBIND
is *not* available on FreeBSD). There are some restrictions
for this option though (which is not mentioned in the Linux
man page).
OTP-14831
|
|
Added support for socket level socket option TIMESTAMP.
OTP-14831
|
|
Added support for socket level socket option RCVLOWAT and SNDLOWAT.
These are both a little strange, at least on Linux. See the man
pages for more info. For instance, sndlowat cannot be set on Linux.
