2015-01-13erts: Extend driver interface with emergency_closeBjörn-Egil Dahlberg
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.

2014-10-16kernel,ssh: Add synchronous user_drv protocolLukas Larsson
Added a put_chars_sync to the protocol that can be used to talk to user_drv and made group use it. This is needed in order to guarantee that bytes has been pushed to the tty port when doing something like this: io:format("halting\n"),erlang:halt(0). Before this change the halting message could be lost in the message queue of the user_drv process, this is no longer possible. This commit also fixes ssh_cli as that plugs itself in as a user_drv process. OTP-12240
2014-10-16erts: Make tty driver non-blockingLukas Larsson
Instead of using blocking call to fwrite, the tty driver now uses non-blocking calls to writev and queues any output data that cannot be written into the driver queue. Without this change an stdout write could block an entire scheduler if for some reason the pseudo tty on the other side does not consume the output of the Erlang shell. OTP-12239

2014-09-12erts: getsockname is not allowed on non-bound socketsLukas Larsson
This only produces an error on win32, but should not really be called on *nix either.

2014-07-22erts: Fix inet close on prebound fdsBjörn-Egil Dahlberg
Inet close must remove fd from select/poll without closing the fd.

2014-05-14Fix efile_openfile() to handle stat() failureMikael Pettersson
If the initial stat() fails then efile_openfile() will still proceed to open() the file. If that succeeds and the caller passed a non-NULL pSize, then it will copy bogus data from the statbuf into *pSize. This has been observed to cause file:read_file/1 to return truncated file data with no error indication. The use case involved a large file system mounted via NFS, with some directories containing large number of files, and NFS mount options that allow the NFS client to return EIO if the NFS server does not respond quickly enough. Depending on the caching state of the client and server machines, a few stat() calls (fewer than 1 per 10 million) would take long enough to trigger EIO errors, but subsequent open() calls would succeed, and read_file/1 would return truncated data. This sequence of events has been observed via "strace" on beam.smp. Signed-off-by: Mikael Pettersson <[email protected]>

2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
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.

2014-03-21zlib: Fix adler32_combine/4 and crc32_combine/4Björn Gustavsson
Since our config.h is included in each source file in the zlib directory, we must make sure that config.h is also included every time zlib functions are called to ensure that definitions of types are consistent. zlib_drv.c did not include config.h, which caused problems on a MacOS X Leopard system. What happened was that HAVE_UNISTD_H was not defined when zlib.h was included. When unistd.h is not known to exist, the type z_off_t will be set to a long (32 bits on this platform). But when the zlib source files were compiled, HAVE_UNISTD_H was defined, unistd.h would be included, and z_off_t would be set to off_t (64 bits; defined in unistd.h). As a result of the mismatch, calls to the adler32_combine() and crc32_combine() would pass only 32 bits in the len2 argument when 64 bits were expected.

2014-02-24ose: Updating event and signal API for OSEJonas Karlsson
2014-02-24ose: Thread priorities configurable from lmconfLukas Larsson
The pattern used for getting the priority from the lmconf is based on the name of the process created. The pattern is: ERTS_%%PROCESS_NAME%%_PRIO with the %%PROCESS_NAME%% replaced by the prefix of the process the priority applies to. eg: ERTS_SCHEDULER_PRIO=24 applies to processes with name SCHEDULER_1, SCHEDULER_2 etc.
2014-02-24ose: Rewrite resolve_signal API for ose driversLukas Larsson
This new API has less impact on the check_io code and also removes the callback from ErlDrvEntry. The downside is that you have to give the resolve function when creating each event. Also the mode if the resolve was removed as this mimics the win32 code and decreases complexity.
2014-02-24ose: OSE port related cleanup and fixesJonas Karlsson
Some OSE cross-chains have problems with system includes being used, so for atleast OSE specific parts we use "" instead of <>.

This is needed because OSE does not use 1 for SEEK_CUR

This is needed because OSE does not have the same integers as unix/win32 for SEEK_ST and friends.
