first (it's a nice API, but JSON APIs there are already enough, this is
purely about the Varlink angle).

I made most of the json.h APIs public, and just placed them in
sd-json.h. Sometimes I wasn't so sure however, since the underlying data
structures would have to be made public too. If in doubt I didn#t risk
it, and moved the relevant API to src/libsystemd/sd-json/json-util.h
instead (without any sd_* symbol prefixes).

This is mostly a giant search/replace patch.

This reverts commit 1e1225614ca1106116dcad9fb37aaeb6106408ab.

This was an incomplete workaround of the race. Now that

16 months agocore/mount: stop generating mount units for cred mounts
Mike Yuan [Tue, 14 May 2024 10:33:32 +0000 (18:33 +0800)] 
core/mount: stop generating mount units for cred mounts

While @poettering wants to keep mount units for credential
mounts, this has brought nothing but pain in real life.

By generating mount units for each cred mount, we had trouble
with default dependencies on them, which causes their stop jobs
to race with unmounting through exec_context_destroy_credentials().
There were several attempts to workaround the problem, but
none seems very graceful: #26959, #28787, #28957, #31360, #32011.
Also, we want to carry over credentials for services that
survive soft-reboot to the new mount tree, and during the practice
the stop of mount units are irritating.

The mentioned problems are ultimately resolved by disabling
default deps: #32799. But after doing that, maybe the next question
should be "why do we generate these mount units at all?"

Let's revisit the whole concept here. First of all, the credential
dirs are supposed to be opaque to users, and hence nobody should
really reference to these mounts directly. Secondly, the lifetime
of credentials is strictly bound to the service units, but nothing
else. Moreover, as more and more users of credentials pop up,
we could end up with hundreds of such mount units, which is
something we handle poorly. And we emit useless UnitRemoved signals,
etc...

As discussed, it seems that eliminating these mount units
is the correct way to go. No real use cases are impacted,
and the lifetime management becomes sane again.

16 months agocore/socket: allow MPTCP protocol
Matthieu Baerts (NGI0) [Mon, 20 May 2024 16:37:17 +0000 (18:37 +0200)] 
core/socket: allow MPTCP protocol

Multipath TCP (MPTCP), standardized in RFC8684 [1], is a TCP extension
that enables a TCP connection to use different paths. It allows a device
to make use of multiple interfaces at once to send and receive TCP
packets over a single MPTCP connection. MPTCP can aggregate the
bandwidth of multiple interfaces or prefer the one with the lowest
latency, it also allows a fail-over if one path is down, and the traffic
is seamlessly re-injected on other paths.

To benefit from MPTCP, both the client and the server have to support
it. Multipath TCP is a backward-compatible TCP extension that is enabled
by default on recent Linux distributions (Debian, Ubuntu, Redhat, ...).
Multipath TCP is included in the Linux kernel since version 5.6 [2]. To
use it on Linux, an application must explicitly enable it when creating
the socket:

  int sd = socket(AF_INET(6), SOCK_STREAM, IPPROTO_MPTCP);

No need to change anything else in the application.

This patch allows MPTCP protocol in the Socket unit configuration. So
now, a <unit>.socket can contain this to use MPTCP instead of TCP:

  [Socket]
  SocketProtocol=mptcp

MPTCP support has been allowed similarly to what has been already done
to allow SCTP: just one line in core/socket.c, a very simple addition
thanks to the flexible architecture already in place.

On top of that, IPPROTO_MPTCP has also been added in the list of allowed
protocols in two other places, and in the doc. It has also been added to
the missing_network.h file, for systems with an old libc -- note that it
was also required to include <netinet/in.h> in this file to avoid
redefinition errors.

thawing might be slow too, so just bump the timeout again.
