If this is not set, it looks like NM shuts down the VPN connection and
calls disconnect() if there is any connectivity change.

This enables GRO offload for inbound ESP-in-UDP packets if the
esp4|6_offload modules are loaded. Note that inbound ESP or ESP-in-UDP
packets won't be visible on layer 3 in Netfilter or tcpdump.
Increase buffer to 32 bytes to hold uint64_t completely and check for
overflows after multiplication with size modifiers.

This allows accepting clients that send proposals with non-optional KE
methods during rekeying, while still accepting clients that use the
previous non-KE default proposals.
This requires a new protocol version as private extensions would enable
unrelated regular extensions, even when sending the private extension
as second attribute (which would work for conditions as they are
explicitly enabled/disabled).
This was originally added with b0e40caafbd7 ("NAT-T conditions were not
inherited during IKE_SA rekeying") in 2008 when there was only a single
inherit() method. Later the inherit_pre() method was added and then
with 094963d1b160 ("ikev2: Apply extensions and conditions before
starting rekeying") in 2014 the extensions and conditions were set
already there.
This avoids conflicts with upstream changes if patched versions of
strongSwan require a number of private extensions and conditions. For
example, the following extensions can be used as usual via the
`enable|supports_extension()` methods:
#define PRIVATE_EXT_1 (EXT_PRIVATE_MARKER | (1<<0))
#define PRIVATE_EXT_2 (EXT_PRIVATE_MARKER | (1<<1))
Defining an enum would also be possible but because the type won't match
the values would have to be cast to `ike_extension_t` when using the
methods.
Similarly, `COND_PRIVATE_MARKER` may be used to define private conditions
that can be used with the `set|has_condition()` methods.
Because the MSB is explicitly not set in `private_extensions|conditions`,
these members may directly be checked against private values, e.g.:
if (this->private_extensions & PRIVATE_EXT_1)
{
}
If this is used, the functionality to set a private key/value/seed for
key exchange methods is removed (including from the interface to avoid
accidentally forgetting to wrap implementations and uses of set_seed()).
The set_seed() method is assigned outside the INIT() macro to avoid
potentially undefined behavior (preprocessing directives in macro
arguments).
The test done by the crypto tester is a simple functionality test.
So far, the timeout value was only used as connect timeout while a
malicious server could accept the connection and then starve us. So use
the timeout for LDAP_OPT_TIMEOUT, too, which affects all synchronous
calls. In particular, ldap_simple_bind_s(), which has no timeout
argument like ldap_search_st().

It seems that scp is sometimes very slow (unclear what causes it as it's
not always the same). Packing up the files with tar performs a lot
better in these situations. And copying the files to multiple hosts
in parallel additionally helps to reduce the time required for these
steps.
Using --overwrite and -h preserves existing symlinks (e.g. for the users
file in /etc/freeradius/3.0) and overwrites the target file instead.
The -m option ignores timestamps when extracting the files as some target
files will be newer than the source. Using -h when packing up files in
load-testconfig allows using symlinks in the test config dirs to files
on the host running the tests.
The file won't exist in the previous location until load-testconfig was
executed once. Since it's not modified by the script it's fine to
load it directly from the original location.

The callbacks provided via ProcessLifecycleOwner are only triggered when
Activities are started. However, when Android triggers the Always-on
VPN it directly starts our VpnService subclass, no Activity. So the
configs were not loaded and the VPN couldn't be initiated with a managed
profile. This ensures the config is loaded right from the start of
the app. And by registering for modifications in onCreate() we can also
use the correct config if the app is never started in-between changes to
the managed profiles and triggering the Always-on VPN.
As described in the previous commit, GCC 15 uses C23 by default and that
changes the meaning of such argument-less function declarations. So
whenever we assign such a function to a pointer that expects a function
with arguments it causes an incompatible pointer type warning. We
could define dedicated functions/callbacks whenever necessary, but this
seems like the simpler approach for now (especially since most uses of
these functions have already been cast).
Besides being clearer, this fixes issues with GCC 15. The latter uses
C23 by default, which changes the meaning of function declarations
without parameters such as
bool return false();
Instead of "this function takes an unknown number of arguments", this
now equals (void), that is, "this function takes no arguments". So we
run into incompatible pointer type warnings all over when using such
functions. They could be cast to (void*) but this seems the cleaner
solution for this use case.
This allows to manually do some testing without having to type commands
to set up a scenario.
Also changes how arguments are parsed (allowing to pass options mixed
with test dirs) and adds some usage output.
