Seems to be required on macOS (libtls tests didn't run before the recent
implicit enabling via pki). Other platforms apparently let accept() fail
if the socket is shutdown/closed in teardown_creds(), macOS apparently
doesn't do that.
When an X.509 certificate has to be renewed it is helpful to use
the old PKCS#10 certificate request as a template, so that the
distinguishedName (DN), the subjectAlternativeName (SAN) and
a certificate profile name don't have to be typed-in again.
The old public key in the existing certreq is replaced with the
new key and the signature is re-generated using the new private key.
In order for libtls to run with the gcrypt libraryi, additionally the
random, pem, gcm, hmac, kdf, x509, constraints, and the curve2519
plugins are needed.
The botan library additionally need the hmac (for HMAC_MD5), x509 and
constraints plugins.
The wolfssl library additionally need the pkcs1, pkcs8, x509 and constraints
plugins.
With the --keyid option private keys stored on a smartcard or in
a TPM 2.0 can be used for public key based client authentication.
With the --certid option the corresponding client certificate
can reside on a smartcard or a TPM 2.0.
The gcm plugin has been added to the default plugins and all
certificate types are loaded to allow the libtls socket unit
tests to run with the strongSwan default plugins.
Currently when a TLS client doesn't have a certificate, it doesn't
send a certficiate payload upon receiving a certificate request
from the TLS server. According to the TLS 1.2 and 1.3 RFCs an
empty certificate payload must be sent.
The msCertificateTypeExtension OID (1.3.6.1.4.1.311.20.2) can
be used in a PKCS#10 certificate request to define a certificate
profile. It consists of an UTF8 string.
pki: profile option
The "ipsec scepclient" tool has been removed and replaced by the
pki subcommands "pki --scep" and "pki --scepca" which implement the
new SCEP RFC 8894 standard that was released in September 2020 and
which supports trusted "certificate renewal" based on the existing
client certificate.

The previous code did not ensure that there was a delay of at least
`try` seconds after each sent request. Instead, whenever the condvar was
signaled, which could be due to retransmitted responses or messages for
unrelated transactions (there could even be spurious wakeups), the counter
was increased and a retransmit sent. So instead of actually waiting for
15 seconds for a response (and sending 4 retransmits over that timespan),
it could happen that all five messages were sent within a second without
enough time to actually receive a response.
Using an absolute timeout that we reuse as long as there was no timeout
and the condvar was signaled for something unrelated, should ensure we
wait at least the intended delay after each sent message.

This allows using the upper parts of the marks for other purposes. For
instance, with `mark_in=mark_out=%unique/0x0000ffff` mark values in the
upper two bytes would not get reset by the rules installed by this plugin.
However, note that in this example the daemon would have to get restarted
after 65'535 CHILD_SAs to reset the counter for unique marks, which is a
global 32-bit counter that's unaware of any masks.
