This is mostly a pure refactoring.
Except for the buggy cases when calling erlang:halt() with a positive
integer in the range -(INT_MIN+2) to -INT_MIN that got confused with
ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT.
Outcome OLD erl_exit(n, ) NEW erts_exit(n, )
------- ------------------- -------------------------------------------
exit(Status) n = -Status <= 0 n = Status >= 0
crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0
The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and
ERTS_DUMP_EXIT are the same as before (even though their values have
changed).

* maint:
Fix inet driver multi timers using new time API
|
|
|
|
When a AF_LOCAL file descriptor is created externally (e.g. Unix
Domain Socket) and passed to `gen_tcp:listen(0, [{fd, FD}])`, the
implementation incorrectly assigned the address family to be equal
to `inet`, which in the inet_drv driver translated to AF_INET instead
of AF_LOCAL (or AF_UNIX), and an `einval` error code was returned.
This patch fixes this problem such that the file descriptors of the
`local` address family are supported in the inet:fdopen/5,
gen_tcp:connect/3, gen_tcp:listen/2, gen_udp:open/2 calls

A new {line_delimiter, byte()} option allows line-oriented TCP-based
protocols to use a custom line delimiting character. It is to be
used in conjunction with {packet, line}.
This option also works with erlang:decode_packet/3 when its first argument
is 'line'.

Caused stack corruption leading to VM crash on windows.
{packet,ssl_tls} is undocumented by the way.

The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.

* nybek/fix_so_linger_zero__simple:
Update prim_inet.beam
Fix socket option {linger, {true, 0}} to abort TCP connections
Apply 'show_econnreset' socket option to send errors as well
Add 'show_econnreset' TCP socket option
|
|
Up until now, if {linger, {true, 0}} is set on the socket and there is
data in the port driver queue, the connection is not aborted until
the port queue is empty and close() is called on the underlying file
descriptor. This bug allows an idle TCP client to prevent a server
from terminating the connection and freeing resources. This patch
fixes the problem by discarding the port queue if the socket is closed
when {linger, {true, 0}} is set.
|
|
Up till now all send errors have been translated into a generic
{error, closed}. This patch allows {error, econnreset} to be
returned on send errors when it is detected that the TCP peer
has sent an RST.
|
|
An ECONNRESET is a socket error which tells us that a TCP peer has sent
an RST. The RST indicates that they have aborted the connection and
that the payload we have received should not be considered complete. Up
until now, the implementation of TCP in inet_drv.c has hidden the
receipt of the RST from the user, treating it as though it was just
a FIN terminating the read side of the socket.
There are many cases where user code needs to be able to distinguish
between a socket that was closed normally and one that was aborted.
Setting the option {show_econnreset, true} enables the user to receive
ECONNRESET errors on both active and passive sockets.
A connected socket returned from gen_tcp:accept/1 will inherit the
show_econnreset setting of the listening socket.
By default this option is set to {show_econnreset, false}.
Note that this patch only enables the reporting of ECONNRESET when
the socket is being read from. It does not report ECONNRESET (or
EPIPE) when the user tries to write to a connection when an RST
has already been received. Currently the TCP implementation in
inet_drv.c hides all such send errors from the user in favour
of returning {error, close}. A separate patch will be needed to
enable the reporting of such errors.

Fix the sorting logic in add_multi_timer() and expand the test case
coverage around this area.

If the driver queue is empty, or the user is requesting a 'read'
shutdown, then the shutdown() syscall is performed synchronously, as
per the old version of shutdown/2.
However, if the user is requesting a 'write' or 'read_write' shutdown,
and there is data in the driver queue for the socket, then the
shutdown() syscall is delayed and handled asynchronously when the
driver queue is written out.
This version of shutdown solves a number of issues with the old
version. The two main solutions it offers are:
* It doesn't block when the TCP peer is idle or slow. This is the
expected behaviour when shutdown() is called: the caller needs
to be able to continue reading from the socket, not be prevented
from doing so.
* It doesn't truncate the output. The current version of
gen_tcp:shutdown/2 will truncate any outbound data in the driver
queue after about 10 seconds if the TCP peer is idle of slow. Worse
yet, it doesn't even inform anyone that the data has been
truncated: 'ok' is returned to the caller; and a FIN rather than
an RST is sent to the TCP peer.
For a detailed description of all the problems with the old version
of shutdown, please see the EEP Light that was written to justify
this patch.

* egil/fix-getifaddrs-realloc/OTP-12445:
erts: Fix getifaddrs realloc ptr mismatch
|
|
When a buffer was exhausted and subsequently a realloc, we could get
an invalid pointer.
For this to occur we would need to have a realloc to lower adresses.
The symptom would be garbage returned from erlang:port_control(Port, 25, [])
(prim_inet:getifaddrs(Port) resulting in a badarg) or a segmentation fault.

Closes all open socket before writing crashdump to file.
|
|
|
|
The intention of this callback is to close all sockets associated to
a port. It is closed only on crashdumps.
This will currently only be used for the epmd port.
|

Handle peer addresses that are unconfirmed (i.e. in state SCTP_UNCONFIRMED).
Handle unknown states instead of using ASSERT
|
|
and usage
|
|
This only produces an error on win32, but should not really be called
on *nix either.

Inet close must remove fd from select/poll without closing the fd.
|
|
|
|
|
|
The inet driver for OSE has to handle signals instead of selects
and thus the wrappers for ready_input/output are a little bit
different. However the majority of the inet code remains the same.
|
|
|
|
This port has support for both non-smp and smp.
It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

* lukas/erts/sendfile_passive_mode_fix/OTP-11614:
erts: fix bug when using passive mode and sendfile
|
|
The bug incorrectly issued driver_select when un-ignoring an fd
for a socket in passive mode, which caused an incorrect error
tuple to be returned when the remote end closed the connection.
