+Subject: [PATCH] Fix probing of C_GetInterface
+
+`p11_dl_symbol (dl, "C_GetInterface")` uses dlsym() to find
+C_GetInterface in the loaded pkcs11 module.  For legacy (pre-3.0) pkcs11
+modules, C_GetInterface is not defined in the module.  But according to
+the documentation of dlsym():
+
+    The search performed by dlsym() is breadth first through the
+    dependency tree of these shared objects.
+
+So if a pkcs11 module links to libp11-kit.so, the C_GetInterface
+implementation in libp11-kit.so itself will be found.  This
+C_GetInterface will return the metadata of p11-kit-proxy.so, causing
+"Refuse to load the p11-kit-proxy.so as a registered module".
+
+To solve the issue, if p11_dl_symbol() returns the C_GetInterface in
+libp11-kit.so itself, we should ignore it and continue trying
+C_GetFunctionList.
