Subject: Fix the return value of OBJ_create
X-Git-Tag: openssl-3.6.0-alpha1~95
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5e34d6476016db7630aed77e927d95dd94fc67b0;p=thirdparty%2Fopenssl.git

Fix the return value of OBJ_create

OBJ_create is supposed to return NID_undef on error
and the newly created NID on success.

Fixes: 88a1fbb8d1b2 ("reduce lock contention when adding objects to ADDED_OBJ hash table")
