What has changed in s6-networking

in 2.7.0.1

skalibs dependency bumped to 2.14.1.0
s6 dependency bumped to 2.12.0.3
s6-dns dependency bumped to 2.3.7.1

in 2.7.0.0

skalibs dependency bumped to 2.14.0.1
s6 dependency bumped to 2.12.0.1
LibreSSL optional dependency bumped to 3.8.2
LibreTLS optional dependency bumped to 3.8.1
s6-tlsc-io has changed interfaces: now it uses stdin/stdout as the local side, and the descriptors given as arguments as the remote side. This allows users to invoke it directly when it is relevant.
Consequently, s6-tlsc and s6-ucspitlsc have changed how they invoke s6-tlsc-io.
The -K option to TLS programs has slightly changed semantics: it now indicates a timeout for the whole handshake.
The -h option to s6-tcpclient, s6-tcpserver-access, s6-tlsclient, and s6-tlsserver, has changed semantics. Previously it was a no-op except to cancel a prior -H option. Now it means that DNS lookups should also include /etc/hosts.

in 2.6.0.0

skalibs dependency bumped to 2.14.0.0
execline optional dependency bumped to 2.9.4.0
s6 dependency bumped to 2.12.0.0
LibreSSL optional dependency bumped to 3.7.3
OpenSSL optional dependency bumped to 1.1.1w
LibreTLS optional dependency bumped to 3.7.0
s6-tcpserver-access does not print a warning on -v 2 or more when it is run without the -i or -x option. It is not needed anymore in order to export TCPLOCALIP and TCPLOCALPORT to the applications.
The tcpserver chain has been unified! s6-tcpserver4, s6-tcpserver6, s6-tcpserver4-socketbinder, s6-tcpserver6-socketbinder, s6-tcpserver4d and s6-tcpserver6d have all disappeared. Instead, there are just 3 programs:
- s6-tcpserver-socketbinder, for socket binding
- s6-tcpserverd, the long-lived process. It now exports TCPLOCALIP and TCPLOCALPORT in addition to PROTO, TCPREMOTEIP, TCPREMOTEPORT and TCPCONNNUM.
- s6-tcpserver, which still has the same interface except that the -4 and -6 options have been removed, and that is still a wrapper around the others.
-e, -4 and -6 options removed from s6-tlsserver

Handshake timeout is now functional with the libtls backend (previously it only was with the bearssl backend).
s6-tlsc-io and s6-tlsd-io now send the SNI server name, if any, in their notification message (when the -d option is active), in the SSL_TLS_SNI_SERVERNAME variable.

in 2.4.0.0

OpenSSL plus LibreTLS can now be used as a backend, since LibreTLS provides an implementation of the libtls API.
skalibs dependency bumped to 2.10.0.0.
execline has been made optional. It's still enabled by default; disabling it with the --disable-execline configure option disables exec file support in s6-tcpserver-access.
New binaries: s6-tlsc-io and s6-tlsd-io (which are now the only binaries to perform actual cryptography); s6-ucspitlsc, and s6-ucspitlsd (for delayed encryption).
s6-tlsc and s6-tlsd have been rewritten as wrappers around s6-tlsc-io and s6-tlsd-io respectively.
