Hi All,
Reference to oe-core branch Jethro
Revision: 69b1e25a53255433262178b91ab3e328768ad725
Hostapd 2.4-r0 build with openssl version 1.0.2d has an issue in compilation
due to no
Compile time support of md4 in 1.0.2d version of openssl .
The compilation issue is undefined reference to EVP_md4 , which is defined
In openssl/1.0.2d-r0/openssl-1.0.2d/crypto/evp/evp.h under the MACRO
OPENSSL_NO_MD4.
The macro OPENSSL_NO_MD4 is enabled only if openssl configuration and generated
makefile define "no-md4"
// place where EVP_md4 is defined
openssl/1.0.2d-r0/openssl-1.0.2d/crypto/evp/evp.h
# ifndef OPENSSL_NO_MD4
const EVP_MD *EVP_md4(void);
# endif
//Makefile which configures no-md4 flag
CONFIGURE_ARGS : no-md4
DEPFLAG= -DOPENSSL_NO_MD4
Hostapd depends on md4 for number of EAP methods which require md4 support .
To disable the use of EVP_md4 function call in function md4_vector , macro
defined in
OPENSSL_NO_MD4 should be used . In case of OPENSSL_NO_MD4 enabled ,
md4_vector returns the value returned by function
openssl_digest_vector(EVP_md4(), num_elem, addr, len, mac);
following patch should be applied in crypto_openssl.c

mac);

}
Has anyone faced this issue or Jethro branch has already taken care or this is
just a version mismatch for openssl and hostpad?
Thanks
