[squid-users] is tls_outgoing_options cipher ignored in squid 7.1?

[Dieter Bloms]

Hello,

I'am running squid on debian bookworm with all patches.
I configured the following ciphers:

tls_outgoing_options cipher=TLSv1.2:!CBC:!kRSA:!DSS:!PSK:!aNULL:!ARIA:!CAMELLIA:!AESCCM:!SHA256:!SHA384 at SECLEVEL=2

With squid 6.13 I get the following ciphers list with the ssllab browser test: https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html

TLS_AES_256_GCM_SHA384 
TLS_CHACHA20_POLY1305_SHA256 
TLS_AES_128_GCM_SHA256 (0x1301)   
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256 
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256 
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 
TLS_EMPTY_RENEGOTIATION_INFO_SCSV 

which look good to me, but when I run squid 7.1 on the same system with
the same config I get the following list:

TLS_AES_256_GCM_SHA384 
TLS_CHACHA20_POLY1305_SHA256 
TLS_AES_128_GCM_SHA256 
TLS_RSA_WITH_AES_128_CBC_SHA 
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA 
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA 
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256 
TLS_RSA_WITH_AES_256_CBC_SHA 
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 
TLS_RSA_WITH_AES_256_GCM_SHA384 
TLS_RSA_WITH_AES_128_GCM_SHA256 
TLS_EMPTY_RENEGOTIATION_INFO_SCSV 

which includes some weak ciphers like:
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_256_GCM_SHA384
...

is this a bug, a feature or a mistake on my side?
