When using vici over RPyC and its (awesome) splitbrain, encoding and decoding
strings fails in vici, most likely because of the Monkey-Patch magic splitbrain
uses.
When specifying the implicit UTF-8 as encoding scheme explicitly, Python uses
the correct method to encode/decode the string, making vici useable in
splitbrain contexts.
If this is the first message by the peer, i.e. we expect MID 0, the
message is not pre-processed in the task manager so we ignore it in the
task.
We also make sure to ignore such messages if the extension is disabled
and the peer already sent us one INFORMATIONAL, e.g. a DPD (we'd otherwise
consider the message with MID 0 as a retransmit).
If the responder never sent a message the expected MID is 0. While
the sent MID (M1) SHOULD be increased beyond the known value, it's
not necessarily the case.
Since M2 - 1 would then equal UINT_MAX setting that MID would get ignored
and while we'd return 0 in the notify we'd actually expect 1 afterwards.
While trap and regular policies now often look the same (mainly because
reqids are kept constant) trap policies still need to have a lower priority
than regular policies to handle unroute/route correctly if e.g. IPComp
is used or the mode changes. But if we use a completely different
priority range that's lower than that of regular policies it is not possible
to install overlapping trap policies. By differentiating trap from
regular policies via the priority's LSB this issue is avoided while
still maintaining the proper ordering of trap and regular policies.
Fixes#1243.
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.
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).
