2018-08-02Fix NIF stack recursion bug and enforce a limitRaimo Niskanen
Fix recursion bug when decoding Constructed value within another value - here the allowed buffer for the recursed decode shall only be the size of the enclosing value, not the whole buffer. Return ASN1_ERROR if BER decode recurses more than about 8 kWords.

2018-01-17asn1_SUITE: Fix failure in xref_export_all/1Björn Gustavsson
The variable 'S' was used twice. If the test case failed because there were unused functions in asn1_SUITE, there would be an ugly badmatch exception instead of the intended nice error message.

2017-08-16Fix broken handling of default values in extensions for PERBjörn Gustavsson
Default values have never worked in extension for PER. Note that for default values in the root part of SEQUENCE, giving a value equal to the DEFAULT value, will result in the same encoding as if asn1_DEFAULT was given. However, that behavior is not promised by the documentation. The documentation says that asn1_DEFAULT should be used for default values. For DEFAULT in extensions, only implement what the documentation promises and nothing more. ERIERL-60

2017-03-27Add a no_native option wherever there is an on_loadKostis Sagonas
This is a poor man's solution that allows to build and test the system with all files compiled to native code simply by setting the ERL_COMPILER_OPTS environment variable. Better solutions, like automatically setting the no_native option whenever the compiler sees an on_load attribute, obviously exist but require more time to implement.

2017-03-14asn1ct_gen_ber_bin_v2: Remove unused codeBjörn Gustavsson
The code is not covered. The code is also not present in the PER backend. Here is a somewhat more formal proof that the code cannot be reached: asn1ct_gen_ber_bin_v2:gen_encode_user/3 calls asn1ct_gen:gen_encode_constructed/4 where Typename is a list of one element. asn1ct_gen:gen_encode_constructed/4 will call asn1ct_gen_ber_bin_v2:gen_encode/3 via asn1ct_gen:gen_types/4. Note that if InnerType in asn1ct_gen:gen_encode_constructed/4 is 'SEQUENCE OF' or 'SET OF', Typename will be extended to a list with two elements. If InnerType in asn1ct_gen:gen_encode_constructed/4 is 'SET', 'SEQUENCE', or 'CHOICE', then asn1ct_gen_ber_bin_v2:gen_encode/3 will be called with the last argument being a #'ComponentType'{}. asn1ct_gen_ber_bin_v2:gen_encode/3 will in that cause extend Typename before calling itself recursively. Therefore, Typename is always a list with at least two elements when the removed code is called.
2017-03-14asn1ct_gen_per: Fix broken dialyzer suppression functionBjörn Gustavsson
ce431409d0daba broke generation of dialyzer suppressions for per and uper. While we are it, add type tests to asn1ct_func:is_used/1 to avoid similar problems in the future.
2017-03-14asn1_erl_nif.c: Correct handling of tags >= 16384Björn Gustavsson
Tags number above 16383 were not decoded correctly in ber_decode_tag(). We could fix the problem, but there does not seem to be any need. First, the only way that high tag numbers can be created is with manual tagging; after 1994 manual tagging is no longer recommended. Second, the ASN.1 playground (http://asn1-playground.oss.com) only supports tags up to 16383 (the same is presumably true for OSS Nokalva's other tools). Therefore, clean up the existing code and make it an explicit 'invalid_tag' error when tags above 13383 are encountered (instead of an implicit 'wrong_tag' error).

2017-02-21encode/decode: Include the stack trace in error returnsBjörn Gustavsson
The generated encode/2 and decode/2 functions can return cryptic error messages. Consider this ASN.1 spec: T DEFINITIONS AUTOMATIC TAGS ::= BEGIN S ::= SEQUENCE { b BOOLEAN, i INTEGER (1..100), j INTEGER (0..7), s OCTET STRING } END In OTP 19, the error terms will look like this: Eshell V8.2 (abort with ^G) 1> asn1ct:compile('T', [ber]). ok 2> rr('T'). ['S'] 3> 'T':encode('S', #'S'{}). {error,{asn1,{encode_boolean,undefined}}} 4> 'T':encode('S', #'S'{b=false}). {error,{asn1,{encode_integer,undefined}}} 5> 'T':encode('S', #'S'{b=false,i=7,j=0}). {error,{asn1,function_clause}} Some error terms are clearer than other. In the first error term, it is clear that the error refers to the 'b' field, since there is only one BOOLEAN in 'S'. The second error term could refer to either 'i' or 'j'. The last error term... well... in this case we can infer that it must refer to 's'. The easiest way to provide more information is to include the stack trace with line numbers in the error term: 3> 'T':encode('S', #'S'{b=false}). {error,{asn1,{{encode_integer,undefined}, [{'T',encode_integer,2,[{file,"T.erl"},{line,240}]}, {'T',enc_S,2,[{file,"T.erl"},{line,102}]}, {'T',encode,2,[{file,"T.erl"},{line,36}]}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {shell,exprs,7,[{file,"shell.erl"},{line,686}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,641}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,626}]}]}}} By looking at the generated Erlang code, we can see that encoding failed for 'i'. This is an compatible change. All that the documentation says is that the format of the error tuple is: {error,{asn1,Description}} With this change, Description is always a tuple: {ErrorDescription,StackTrace} Alternatives considered: Providing more information in the error term itself and make sure there can be no 'function_clause', 'badarg', or 'badmatch' exceptions. That would be possible, but it would require a lot of work and it would increase the size of the generated code and make it slower. Therefore, this solution was rejected.
2017-02-21PER decoding: Be less verbose for invalid ENUMERATEDBjörn Gustavsson
When an invalid value is encountered when trying to decode an ENUMERATED, the exception can be quite verbose. Here is an actual example from NBAP-PDU-Contents: _ -> exit({error,{asn1,{decode_enumerated,{V4@V3,[chCode1div1,chCode2div1,chCode2div2,chCode4div1,chCode4div2,chCode4div3,chCode4div4,chCode8div1,chCode8div2,chCode8div3,chCode8div4,chCode8div5,chCode8div6,chCode8div7,chCode8div8,chCode16div1,chCode16div2,chCode16div3,chCode16div4,chCode16div5,chCode16div6,chCode16div7,chCode16div8,chCode16div9,chCode16div10,chCode16div11,chCode16div12,chCode16div13,chCode16div14,chCode16div15,chCode16div16]}}}}) Listing the possible values for an ENUMERATED when decoding fails is not helpful and increases the code size (it would have made somewhat more sense to list the possible values if *encoding* failed).
2017-02-17PER encoding: Emit comments about each attributeBjörn Gustavsson
To make it easier to find your way in the generated code, add a comment about each attribute in the generated code for SEQUENCE and SET.
