[Pkg-openssl-devel] Bug#848212: libssl-dev package missing ECDSA_SIG_st structure definition

[David Caldwell]

Package: libssl-dev
Version: 1.1.0c-2
Severity: normal

Dear Maintainer,

I'm getting errors compiling a program that uses OpenSSL ECDSA
code:

  libabi/src/ossl_ec.c: In function ‘OSSL_ECDSA_do_verify_rs’:
  libabi/src/ossl_ec.c:204:15: error: storage size of ‘sig’ isn’t known
       ECDSA_SIG sig;
                 ^~~
  libabi/src/ossl_ec.c: In function ‘OSSL_ecdsa_sig_get_r’:
  libabi/src/ossl_ec.c:222:56: error: dereferencing pointer to incomplete type ‘ECDSA_SIG {aka const struct ECDSA_SIG_st}’
       return (const OSSL_BIGNUM*) ((const ECDSA_SIG*)sig)->r;
                                                        ^~

I notice that libssl-dev doesn't appear to define the ECDSA_SIG_st
structure:

  $ dpkg -L libssl-dev | grep '\.h' | xargs -d\\n grep ECDSA_SIG_st
  /usr/include/openssl/ec.h:typedef struct ECDSA_SIG_st ECDSA_SIG;


The structure *is* included in the openssl 1.1.0c source file
(openssl_1.1.0c.orig.tar.gz):

  $ grep -r ECDSA_SIG_st openssl-1.1.0c
  openssl-1.1.0c/include/openssl/ec.h:typedef struct ECDSA_SIG_st ECDSA_SIG;
  openssl-1.1.0c/crypto/ec/ec_lcl.h:struct ECDSA_SIG_st {


When I paste the ECDSA_SIG_st structure definition into the code, it
compiles and runs ok. I think this code is accidentally missing from the
debian package. But I'm also not familar with this code, so perhaps I'm just
misunderstanding how it's all supposed to work.
