Otherwise, the output is buffered when e.g. piping the output to another
command (or file). And it avoids having to call fflush() in the
interactive mode.
Fixes#3404.
The file is usually opened/created by root, however, if user/group IDs
are configured and the configuration is reloaded, the file will be reopened
as configured user. Like with UNIX sockets we only attempt to change
the user if we have CAP_CHOWN allowing a start as regular user.
We don't have chown() on Windows, so check for it.
Enables us to ignore any future kernel features for routes unless
we actually need to consider them for the source IP routes.
Also enables us to actually really skip IPsec processing for those networks
(because even the routes don't touch those packets). It's more what
users expect.

This is mainly an issue on FreeBSD where the current kernel still only
allows the daemon to use reqids < IPSEC_MANUAL_REQID_MAX (0x3fff = 16383).
Fixes#2315.
Charon refuses to make use of algorithms IDs from the private space
for unknown peer implementations [1]. If you chose to ignore and violate
that section of the RFC since you *know* your peers *must* support those
private IDs, there's no way to disable that behavior.
With this commit a strongswan.conf option is introduced which allows to
deliberately ignore parts of section 3.12 from the standard.

Previously, we simply used the lifetimes of the first
proposal/transform, which is not correct if the initiator uses different
lifetimes in its proposals/transforms.
If an IKE_SA is terminated while a task is active, the delete task is
simply queued (unless the deletion is forced). If the active task times
out before any optional timeout associated with the termination hits, the
IKE_SA previously was reestablished without considering the termination
request.
Fixes#3335.
This is the recommended location and import config as it allows running the
tests against installed versions of the package. And while the test file
itself is automatically included in the source distribution this way, the
__init__.py file is not, so we still have to update MANIFEST.in.
RFC 7296, section 2.21.3:
If a peer parsing a request notices that it is badly formatted (after
it has passed the message authentication code checks and window
checks) and it returns an INVALID_SYNTAX notification, then this
error notification is considered fatal in both peers, meaning that
the IKE SA is deleted without needing an explicit Delete payload.

This happened when installing a duplicate bypass policy for a locally
connected subnet. The destructor and the kernel-net part already
handle this correctly.
This avoids having to register certificates with authority/ca backends
beforehand, which is tricky for intermediate CA certificates loaded
themselves via authority/ca sections. On the other hand, the form of
these URLs can't be determined by config backends anymore (not an issue
for the two current implementations, no idea if custom implementations
ever made use of that possibility). If that became necessary, we could
perhaps pass the certificate to the CDP enumerator or add a new method
to the credential_set_t interface.
Don't define structs for macOS as we don't need them (that's true for
most of the others too, though) and at least one is defined inside an extra
ifdef.
