Is there any way of building Nexmon at the moment on Raspberry Pi OS? While I'm able to download an older image which uses the 5.4 kernel, the raspberrypi-kernel-headers seem...

Of course, here you go: Script `test.py`: ```py import socket import scapy.layers.tls.all as tls client_hello = tls.TLSClientHello( ciphers=[ tls.TLS_CHACHA20_POLY1305_SHA256 ], ext=[ tls.TLS_Ext_ServerName(servernames=[tls.ServerName(servername=b"localhost")]), tls.TLS_Ext_ExtendedMasterSecret(), tls.TLS_Ext_EncryptThenMAC(), tls.TLS_Ext_SupportedGroups(groups=["x25519"]), tls.TLS_Ext_SupportedVersion_CH(versions=["TLS 1.3"]), tls.TLS_Ext_SignatureAlgorithms(sig_algs=["sha256+rsaepss"]), tls.TLS_Ext_KeyShare_CH(client_shares=[tls.KeyShareEntry(group="x25519")]), ],...

I also just discovered that the issue persists when announcing `TLS_AES_128_GCM_SHA256` as only cipher suite. Initially, I thought it was only a issue for Chacha due to the mentioned branching...

Thanks for your clarifications. I was aware of the second aspect but not of the first one. > We really need to have examples on https://scapy.readthedocs.io/ regarding various common TLS...

With `AIOHTTP_NO_EXTENSIONS=1` there seems to be no issue

I've narrowed the issue a bit down. It has to do with the `Upgrade: h2c` header in the request. A more minimal reproduction example: **Server** ```py import aiohttp.web async def...

If you still think it is an issue with `llhttp`, could you open an issue over there? I'm not familiar with that project, so the bug report would probably be...
