Can lsquic provide an api to get connection sni?

[wangfuyu]

When on_new_conn be called, I hope lsquic can have an api to get sni from conn, which same with the 3rd ea_lookup_cert para.
like: lsquic_conn_get_hostname or lsquic_conn_get_sni

I try to add new api, but I find enc_session->hs_ctx.sni.str maybe changed occasionally before on_new_conn be called.
I have following code by gdb, and sure that destroy_conn(mini conn) is called after on_new_conn be called, So I'm puzzled here.

What I have changed to lsquic:

1. Add a new elem "hostname" to struct lsquic_conn

2. in func get_sni_SSL_CTX, I save sni to mini conn;
   enc_session->es_conn->hostname = enc_session->hs_ctx.sni.str;

3. in func lsquic_gquic_full_conn_server_new, deliver sni to full conn from mini conn
   conn->fc_conn.hostname = lconn_mini->hostname;

4. on_new_conn, I get sni from conn

It would be easier to discuss your proposal if it were a PR: then we could look at actual code.

I created a pull request that should implement this feature, providing a method

const char* lsquic_conn_get_sni(struct lsquic_conn*);

Cheers

Fixed in 2.27.4
