From 3334c0c7b831ecf47738c713fd764eef891a298a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Mon, 6 Mar 2017 14:28:31 +0100 Subject: asn1_erl_nif.c: Correct handling of tags >= 16384 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). --- lib/asn1/test/asn1_SUITE.erl | 1 + lib/asn1/test/asn1_SUITE_data/HighTagNumbers.asn1 | 17 +++++++++++++++++ 2 files changed, 18 insertions(+) create mode 100644 lib/asn1/test/asn1_SUITE_data/HighTagNumbers.asn1 (limited to 'lib/asn1/test') diff --git a/lib/asn1/test/asn1_SUITE.erl b/lib/asn1/test/asn1_SUITE.erl index 580c919b9d..d99190b6b0 100644 --- a/lib/asn1/test/asn1_SUITE.erl +++ b/lib/asn1/test/asn1_SUITE.erl @@ -1108,6 +1108,7 @@ test_modules() -> "From", "H235-SECURITY-MESSAGES", "H323-MESSAGES", + "HighTagNumbers", "Import", "Int", "MAP-commonDataTypes", diff --git a/lib/asn1/test/asn1_SUITE_data/HighTagNumbers.asn1 b/lib/asn1/test/asn1_SUITE_data/HighTagNumbers.asn1 new file mode 100644 index 0000000000..b681063965 --- /dev/null +++ b/lib/asn1/test/asn1_SUITE_data/HighTagNumbers.asn1 @@ -0,0 +1,17 @@ +HighTagNumbers DEFINITIONS ::= +BEGIN + +S ::= SEQUENCE { + a [127] INTEGER, + b [128] INTEGER, + c [150] INTEGER, + d [207] INTEGER, + e [255] INTEGER, + f [256] INTEGER, + g [7777] INTEGER, + h [9999] INTEGER, + i [16382] INTEGER, + j [16383] INTEGER +} + +END -- cgit v1.2.3
