Subject: [PATCH] openssl: Remove deprecated functions from des_encrypt()
|
|
|
|
NetworkManager-CI detected systematic failures on test scenarios using
|
|
MSCHAPv2 when wpa_supplicant uses OpenSSL-3.0.0.
|
|
The 'test_module_tests.py' script also fails, and the following log is
|
|
shown:
|
|
|
|
1627404013.761569: generate_nt_response failed
|
|
1627404013.761582: ms_funcs: 1 error
|
|
|
|
It seems that either DES_set_key() or DES_ecb_encrypt() changed their
|
|
semantic, but it doesn't make sense to fix them since their use has been
|
|
deprecated. Converting des_encrypt() to avoid use of deprecated
|
|
functions proved to fix the problem, and removed a couple of build
|
|
warnings at the same time.
