The kernel now allows a 0 replay window with ESN for SAs that are
explicitly tagged as outbound SAs. But not just that, it actually
rejects outbound SAs with replay windows > 0. So we add a version check
to control the replay window size. Note that adding the attribute
unconditionally would be fine even for older kernels, but if somebody
backports the direction patches, the installation of outbound SAs might
fail if the replay window is not adjusted accordingly.
When targeting Android 14, we get a "Background activity launch blocked!"
exception when trying to start the connection in the background (closing
the drawer works). Which is apparently a bug:
https://issuetracker.google.com/issues/305035828
The workaround here is kinda ugly. In particular, because it's not
possible anymore since a few versions to open a dialog that allows users
to directly grant the required permission to the app. We can only open
the generic settings dialog where users have to search for the app and
grant the permission themselves (we could add a dialog with an explanation
similar to the one for the power whitelist if necessary). Hopefully this
gets fixed at some point (the current beta of Android 15 still has the
same bug, though).
The previous code had some issues because it handled each child config
separately. Not only was this quite inefficient because all IKE_SAs had
to be enumerated for every config, it also caused problems with the check
for other CHILD_SAs in order to decide whether to delete the IKE_SA or
not. Because CHILD_SAs are deleted with an INFORMATIONAL exchange, they
are not immediately gone. This caused a race condition and with more
than one child config and SAs the IKE_SA could be kept because it
could appear as if other, unrelated CHILD_SAs were still there.
Another race condition, which is fixed by the previous commit, occurred
when only changing child configs. Then it could happen that the code
deemed the IKE_SA empty and a delete for it was queued. If that happened
while the IKE_SA was deleting one of the CHILD_SAs (or was busy with some
other exchange), the IKE_SA was not switched to IKE_DELETING. So it
looked usable and create-child tasks for the updated configs might have
gotten queued. Unfortunately, once the ike-delete task is eventually
executed, these tasks would be gone and the replacement CHILD_SAs never
created. This commit additionally avoids actually deleting the IKE_SA
even if all child configs change or get removed if any new CHILD_SAs are
to be initiated.
The IKE_SA might be busy with a different task while a request to
terminate it is getting queued, we don't want to use such an IKE_SA to
initiate new CHILD_SAs as these tasks will get lost once the IKE_SA is
terminated.
The empty array of rules for `assert_message_empty()` and the resulting
size 0 triggers warnings like these:
allocation of insufficient size '0' for type 'listener_message_rule_t' with size '12'
Using calloc() with `nmemb` set to 0 triggers the same warning.
The number of elements is the first argument, their size the second.
The previous code triggered the following warning:
'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument
Instead of just adding the offset internally, this way the reported
base address is always the first assignable address (e.g. for
192.168.0.0/24 vs. 192.168.0.1/24).

If the regular daemon is running, it creates an unconditional routing
rule for the routing table. The rule that charon-nm tries to create,
which excludes marked IKE/ESP traffic to avoid a routing loop, then
can't be installed and we'd end up with said loop.

As recommended by RFC 2985, section 5.4.1:
ChallengePassword attribute values generated in accordance with this
version of this document SHOULD use the PrintableString encoding
whenever possible. If internationalization issues make this
impossible, the UTF8String alternative SHOULD be used.
Even though the RFC continues with
PKCS #9-attribute processing systems MUST be able to recognize and
process all string types in DirectoryString values.
there might be older SCEP server implementations that don't accept
UTF8String-encoded passwords. In particular because previous versions of
PKCS#9 defined this attribute's type as a CHOICE between PrintableString
and T61String.

Can be useful if the CID inside the VM is not known.
The \htmlonly\endhtmlonly hack is used to avoid compiler warnings due
to /* inside a block comment.
If a base address is configured, we don't expect the pool to be empty,
so reject the creation (e.g. with the broadcast address as base).

There are definitions of RNG in <wolfssl/wolfcrypt/settings.h> and
<wolfssl/wolfcrypt/random.h> that play havoc with the literal RNG being
used in the expansions of PLUGIN_*(RNG, ...) when ##-concatenated to
build the enum value FEATURE_RNG.
The #undef in wolfssl_cmmon.h only had an effect if wolfSSL was built
with EdDSA or FIPS enabled, otherwise, the headers that define RNG were
not pulled in before it.

This is a patch from the OpenWrt package sources necessary to adapt to
changes from 2008 that abstracted the option datatype (added a list
type).

With GCC 13, the compiler apparently applies new aliasing optimizations
when compiled with -O2 and without -fno-strict-aliasing. This caused
the application of the second padding bit, where the state was accessed
via uint8_t[], to be moved before the loop that absorbs the buffer into
the state, where the state is accessed via uint64_t[], resulting in
incorrect output. By only accessing the state via uint64_t[] here the
compiler won't reorder the instructions.
musl's headers define a lot of networking structs. For some, the
definition in the Linux UAPI headers is then suppressed by e.g.
__UAPI_DEF_ETHHDR.
Since we included musl's net/ethernet.h, which includes netinet/if_ether.h
that defines `struct ethhdr` (and the above constant), **after** we
include linux/if_ether.h, there was a compilation error because the
struct was defined multiple times.
However, simply moving that include doesn't fix the problem because for
ARP-specific structs the Linux headers don't provide __UAPI_DEF* checks.
So instead of directly including the linux/ headers, we include those
provided by the C library. For glibc these usually just include the
Linux headers, but for musl this allows them to define the struct
directly. We also need to move if.h and add packet.h, which define
other structs (or include headers that do so) that we use.

The previous option caused such requests to be enabled if not explicitly
disabled, which only the vici plugin did, for all other backends requests
would have been sent.

Only the vici plugin previously set OCSP_SEND_REPLY explicitly, all other
backends would have defaulted to OCSP_SEND_BOTH.
