Description of problem:
The implementation of record_size_limit extension in GnuTLS is not RFC 8449 compliant, with multiple issues present
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run tlsfuzzer test-record-size-limit.py
'change size in TLS 1.2 resumption'
'change size in TLS 1.3 session resumption'
'check if server accepts maximum size in TLS 1.0'
'check if server accepts maximum size in TLS 1.3'
'check if server accepts minimal size in TLS 1.0'
'check if server accepts minimal size in TLS 1.1'
'check if server accepts minimal size in TLS 1.2'
'check if server accepts minimal size in TLS 1.3'
'check interaction with sha256 prf'
'check interaction with sha384 prf'
'check server sent size in TLS 1.0'
'check server sent size in TLS 1.3'
'drop extension in TLS 1.3 session resumption'
'modified extension in 2nd CH in HRR handshake'
'padded extension in TLS 1.2'
'padded extension in TLS 1.3'
'renegotiation with changed limit'
'renegotiation with dropped extension'
'too large record in TLS 1.2'
'too large record payload in TLS 1.3'
no test fail
should we still consider this a blocker ?
It seem like it will affect only a specific and restricted scenario and could be easily fixed after GA.
This issue was set to high priority because it impacts the core functionality of the component for a small amount of users.
