2013-01-23Fix efile_drv crash when using async thread poolFilipe David Borba Manana
When using the async thread pool and compressed files, when an efile driver port instance is shutdown, the efile_drv stop callback closes the file descriptor (a gzFile instance actually) - this is dangerous if at the same time there's an async thread performing an operation against the file, for example calling invoke_read(), which can result in a segmentation fault, or calling invoke_close() which double closes the gzFile and this in turn causes 2 consecutive calls to driver_free() against same gzFile instance (resulting in later unexpected crashes in erl_bestfit_alloc.c for example). The following test program makes the emulator crash when using the async thread pool: -module(t2). -export([t/1]). t(N) -> file:delete("foo.bar"), % Use of 'compressed' option, for creating/writing the file, % is irrelevant. It only matters when opening it later for % reads - a non-compressed file open with the 'compressed' % option goes through an internal gzFile handle (instead of % a plain integer fd), just like a compressed file. %{ok, Fd} = file:open("foo.bar", [raw, write, binary]), {ok, Fd} = file:open("foo.bar", [raw, write, binary, compressed]), ok = file:write(Fd, <<"qwerty">>), ok = file:close(Fd), Pid = spawn_link(fun() -> process_flag(trap_exit, true), loop(N) end), Ref = erlang:monitor(process, Pid), receive {'DOWN', Ref, _, _, _} -> ok end. loop(0) -> ok; loop(N) -> Server = self(), Pid = spawn(fun() -> {ok, Fd} = file:open("foo.bar", [read, raw, binary, compressed]), Server ! continue, % Comment the file:read/2 call to make the file:close/1 call much % more likely to crash or end up causing efile_drv to close twice % the fd (gzFile), which will make the emulator crash later in the % best fit allocator (erl_bestfit_alloc.c). _ = file:read(Fd, 5), file:close(Fd) end), receive continue -> ok end, exit(Pid, shutdown), loop(N - 1).

2013-01-22Teach encode functions to accept a bitstring term for a BIT STRINGBjörn Gustavsson
We do it in the simplest possible way by converting the bitstring to a compact bitstring tuple. The encoding of BIT STRINGs should be cleaned up and optimized.
2013-01-22Fix EXTERNAL 1990/1994 conversion information lossBjörn Gustavsson
There are two different definitions of the EXTERNAL data type in ASN.1: the original from 1990 and an updated from 1994. Both defintions are encoded in the same way (in BER). There are still systems in use that use the old definition of EXTERNAL, so the asn1 application must still support both. It has been decided that the asn1 application should handle both the forms without any compiler options. Internally the asn1 application uses the 1990 definition. The encode functions will accept both definitions, but translate the 1994 format to the 1990 format if needed. When decoding, it will decode to the 1990 definition format first and then translate to the 1994 defintion format. One problem with this approach is that the conversion to the 1994 format may not be loss-less (where the 1990 defintion had a CHOICE between an OPEN TYPE, OCTET STRING, or BIT STRING, the 1994 definition only supports an OCTET STRING), and therefore it might not be possible to correctly re-encode the data in the 1990 format. It seems that the only reliable way to handle that problem is to not do the conversion to the 1994 format if the conversion is not loss-less. (There is an attempt when translating to the 1990 format to recover the CHOICE alternative based on the Erlang type of the data value, but that is neither reliable nor future-proof.) That is, when decoding an EXTERNAL value, the resulting tuple could either conform to the 1990 or 1994 definition, and applications must be prepared to handle that. The mail conversation where this issue was first reported can be found here: http://erlang.org/pipermail/erlang-questions/2011-April/057697.html Reported-by: Harald Welte <[email protected]>

Dialyzer will warn for default clauses that cannot possible match.
2013-01-22Slightly optimize per encoding of large INTEGERs with constraintsBjörn Gustavsson
2013-01-22BER run-time: Refactor decoding of string data typesBjörn Gustavsson
In the BER run-time code (asn1rtt_ber), there is a general function for decoding a string: decode_restricted_string(Tlv, Range, StringType, TagsIn) But the StringType argument is not important. It is only used internally in asn1rtt_ber to distinguish universal strings and BMP strings from other strings. By slightly refactoring the string decoding code, we can eliminate the StringType argument and a subsequent run-time test on the string type. That will slightly reduce code size, slightly increase speed, and eliminate Dialyzer warnings.
