Currently supported by libipsec and PF_KEY on macOS (FreeBSD, like Linux,
reports the time the SA was first used in sadb_lifetime_usetime - it also
triggers rekeyings based on that, which Linux doesn't, it also triggers
them if an SA is never used).
Apparently not installed anymore in the latest build image. If it's
missing, we see errors like these:
configure.ac:38: error: possibly undefined macro: AC_DEFINE
This was the order before 46a6b062822c ("openssl: Only announce ECDH
groups actually supported by OpenSSL") but that's not really the reason
for this change. It's related to the Android app, where we previously
didn't support these DH groups in BoringSSL and added the curve25519
plugin after the openssl plugin instead. This resulted in the same
order, i.e. ECDH groups before curve25519. With the switch to OpenSSL
and the mentioned commit, this changed and curve25519 was now the first
group that was proposed and used for the KE payload. Not really an
issue you'd think, however, there are apparently Zyxel Firewalls with
older firmware versions (some forum posts mentioned a fix in V5.31) that
can't handle KE payloads with DH groups > 21 (ecp521). So with
curve25519 (31) proposed in the KE payload, they silently dropped the
IKE_SA_INIT request and no connection could be established.
`public` is returned, but previously only if a trusted key was found.
We obviously don't want to return untrusted keys and since the reference
was correctly destroyed after determining the key type, this later caused
a double-free.

This adds support for the new "packet" hardware offload feature that's
added to the Linux kernel with 6.2. In this mode, the device handles
the complete framing of the ESP packet as well as the policy checks,
in addition to the crypto.
For the IKE sockets, port-based bypass policies are automatically
offloaded to devices that support it.
Closesstrongswan/strongswan#1462
While this uses the same mechanism, it's not necessary to explicitly
enable port_bypass, the regular socket policies work fine to bypass any
software policies.
Keep the kdf plugin because of AES-XCBC (and CAMELLIA-XCBC, which is now
supported due to OpenSSL). Other plugins like fips-prf, pubkey or pkcs8
were never actually used by the app. The random plugin might have been
necessary with early versions.
The build script requires the paths to the NDK and OpenSSL sources.
It runs the build in a Docker container, by default. But if the required
tools are installed on the system (currently jq, make and perl) it can
also be run directly on the system by defining NO_DOCKER.
A relatively recent version of the NDK is required (the pre-built
toolchains are required).
If libcurl is built with MultiSSL support (not the case for e.g.
Debian/Ubuntu, which ship separate, conflicting libraries), this allows
selecting the SSL/TLS backend libcurl uses.
Only older versions of OpenSSL and GnuTLS need special treatment, so we
now accept all other backends (e.g. "(SecureTransport) OpenSSL/1.1.1s"
on macOS).
Whenever we remove support for the affected versions of the mentioned
libraries, we can remove the corresponding *-threading plugin feature
and the code here.
