If charon.prefer_configured_proposals is disabled select() is called on
the received proposal. This incorrectly set the SPI to 0 as the
configured proposal has no SPI set.
Fixes#2190.
The Optimistic Duplicate Address Detection (DAD) seems to fail in some
cases (`dadfailed` in `ip addr`) rendering the virtual IP address unusable.
Fixes#2183.
This implements rule 6 of RFC 6724 using the default priority table,
so that e.g. global addresses are preferred over ULAs (which also have
global scope) when the destination is a global address.
Fixes#2138.
By default, the kernel incorrectly uses an 8 byte alignment, which is
mandatory for IPv6 but prohibited for IPv4. For many algorithms this
doesn't matter but that's not the case for HMAC_SHA2_256_128.
Since 2.6.39 the kernel can be explicitly configured to use a 4 byte
alignment.
Otherwise, we'd end up with an empty TS list, which is not valid.
Because end->tohost is set to !end->subnets in starter the removed branch was
never used.
Allows reloading strongswan.conf, the loggers, and the plugins in
charon-systemd by sending a SIGHUP (as already supported by charon).
Loggers are now also reloaded by VICI's `reload-settings` command (works
with both daemons).
Fixes#2222.
The file format is documented on the wiki.
URLs to .sswan files may be intercepted and downloaded files with a media
type of application/vnd.strongswan.profile may also be opened (the file
extension doesn't matter in that case). Whether downloaded files for which
the media type is not correct but the extension is .sswan can be opened
depends on the app that issues the Intent. For instance, from the default
Downloads app it won't work due to the content:// URLs that do not contain
the file name but when opening the downloaded file from within Chrome's
Downloads view it works as these Intents use file:// URLs, which contain
the complete file name (the latter requires a new permission).
Adds a permanent notification while connected (or connecting), which
allows running as a foreground service, which in turn should prevent
Android from terminating the service when low on memory.
Also adds support for ChaCha20/Poly1305 AEAD and Curve25519 DH.
This avoids triggering additional errors via e.g. ike_updown() that
might cause the error message displayed in the GUI to change if the
status fragment is recreated.

Checking for `main` produces code like this in the test program:
int
main ()
{
return main ();
;
return 0;
}
This recursive call results in a warning message with some compilers (e.g.
Clang in newer Xcode versions: "all paths through this function will call
itself [-Winfinite-recursion]"), which lets the tests fail when compiling
with -Werror.
The log level was incorrectly set to the same value for all groups.
Fixes: dac15e03c8 ("bus: Fix maximum log levels when mixing log/vlog
implementing loggers")
So far every "newer" CRL (higher serial or by date) replaced an existing
"older" CRL. This meant that delta CRLs replaced an existing base CRL
and that base CRLs weren't added if a delta CRL was already stored. So
the base had to be re-fetched every time after a delta CRL was added.
With this change one delta CRL to the latest base may be stored. A newer
delta CRL will replace an existing delta CRL (but not its base, older
base CRLs are removed, though). And a newer base will replace the existing
base and optional delta CRL.
This was added a few years ago because pki --signcrl once encoded serials
incorrectly as eight byte blobs. But still ensure we have can handle
overflows in case the serial is encoded incorrectly without zero-prefix.
BoringSSL only supports a limited list of (hard-coded) algorithms via
EVP_get_cipherbyname(), which does not include AES-GCM. While BoringSSL
deprecated these functions they are also supported by OpenSSL (in BoringSSL
a completely new interface for AEADs was added, which OpenSSL currently does
not support).
Adds checks for proposals parsed from strings. For instance, the presence
of DH, PRF and encryption algorithms for IKE are now enforced and AEAD and
regular encryption algorithms are not allowed in the same proposal anymore.
Also fixed is the mapping of the aes*gmac keywords to an integrity algorithm
in AH proposals.
We parse aes*gmac as encryption algorithm, which we have to map to an
integrity algorithm. We also make sure we remove all other encryption
algorithms and ensure there is an integrity algorithm.
Adds the ability to parse KEY_ANY keys via the pkcs1 and openssl plugins.
This is then used in the pki utility, where private keys may now be
loaded via `priv` keyword instead of having to specify the type of the key
explicitly. And swanctl can load any type of key from the swanctl/private
directory.
If a responder is natted it will usually be a static NAT (unless it's a
mediated connection) in which case adding these notifies makes not much
sense (if the initiator's NAT mapping had changed the responder wouldn't
be able to reach it anyway). It's also problematic as some clients refuse
to respond to DPDs if they contain such notifies.
Fixes#2126.
Sends a DELETE when rekeyed IKE_SAs are deleted. This fixes issues with
peers (e.g. Cisco) that continue to send DPDs on the old SA and then
delete all SAs if no response is received. But since the DELETE could get
dropped this might not fix the issue in all cases.
Also, when terminating an IKE_SA DELETES for all CHILD_SAs are now sent
before sending one for the IKE_SA and destroying it.
Fixes#2090.
