(ITS#7285) Mozilla NSS: default cipher suite always selected

Full_Name: Tim Strobell Version: HEAD OS: RHEL6 URL: ftp://ftp.openldap.org/incoming/tim-strobell-2012060401.patch Submission from: (NULL) (2001:480:20:112:210:18ff:fe19:b000)

When using NSS, the default cipher suite selection is used even when TLSCipherSuite is explicitly specified. This behavior was introduced in the patch provided in ITS#6790.

At tls_m.c:2221...

if ( lt->lt_ciphersuite && tlsm_parse_ciphers( ctx, lt->lt_ciphersuite )) { [ error, return ] } else if ( tlsm_parse_ciphers( ctx, "DEFAULT" ) ) { [ error, return ] }

tlsm_parse_ciphers returns 0 on success; the else path is always followed and overrides the previous cipher suite selection.
