The 5.4.0 update changed the default bignum implementation to what
could explicitly be enabled via `--enable-sp-math-all`. Since this uses
fixed-sized buffers sufficient for key sizes of SP_INT_BITS, with a default
of 4096, modp6144 and modp8192 didn't work anymore (wc_DhGenerateKeyPair()
returned MP_EXPTMOD_E). So we have to adapt the feature checks for this.
To support the larger DH groups we can either increase the buffer size
via `--with-max-rsa-bits` or add `--enable-heapmath` so buffers get
(re-)allocated as needed. We go with the latter for now.
A recent security fix for Git added a fatal error if the directory that
contains the .git directory is not owned by the user that runs git in
that directory tree:
Determine strongSwan version fatal: unsafe repository ('...' is owned by someone else)
To avoid this, we call the git commands as owner of the source
directory (the script has to run as root, so this is no problem).
The user/group ID and name is now also determined via `stat(1)` so it
directly depends on the actual source dir and should work even when not
using sudo.
The logrotate function causes the apt history to be split into
several parts at arbitrary points in time. If history.log only
is parsed then some package installation changes stored in
zipped backup history files might get lost.
Thus sw-collector now searches all backup history files until
a date older than the current event stored in the collector.db
database is found, so that no entries get overlooked.
Use a Debian-based Docker container to run the unit tests for charon-tkm,
once without and once with TKM running. The container can also be used
locally to run the tests (see comments in the Dockerfile).
New versions of Bind limit the maximum UDP message size to 1232 bytes,
which is the same that newer versions of libunbound propose as maximum via
EDNS in requests, so increasing the limit on the server wouldn't help.
Instead we allow DNS via TCP so the client can switch after receiving the
truncated UDP response.
With the update to Python 3 the encoding of the values in vici messages
changed to bytestrings (the keys are properly decoded). And getting the
first CHILD_SA also needs a change.
The logger is now also initialized after daemonizing to avoid that opened
sockets are closed etc.
