-Subject: [PATCH] ustream-ssl: skip writing pending data if .eof is true after
|
|
|
- connect
|
|
|
-
|
|
|
-Check the .eof member of the underlying ustream after the call to
|
|
|
-__ustream_ssl_connect() since existing users of the library appear
|
|
|
-to set the eof flag as a way to signal connection termination upon
|
|
|
-failing certificate verification.
|
|
|
-
|
|
|
-This is a stop-gap measure to address TALOS-2019-0893 but a proper
|
|
|
-API redesign is required to give applications proper control over
|
|
|
-whether certificate failures are to be ignored or not and the default
|
|
|
-implementation without custom callbacks should always terminate on
|
|
|
-verification failures.
