For bastions using JIT MFA, where MFA can be requested when
attempting to connect through specific groups, or when using
some commands, with respect to MFA being enforced at connection
time directly through the sshd authentication process, one can
now request MFA validation in advance, to workaround problems
in commands such as ``clush`` or ``batch``, and interactive mode.
To enhance the readability and visibility of important messages
(such as critical ones). This can be disabled with the `allowUTF8`
global option set to `false`. It's never enabled if the user locale
or their terminal don't seem to support it.
All connections and plugin executions emit two logs, an 'open' and
a 'close' log. We now add all the details of the connection to
the 'close' logs, those that were previously only available in the
corresponding 'open' log. This way, it is no longer required to
correlate both logs with their uniqid to have all the data:
the 'close' log should suffice. The 'open' log is still there if
for some reason the 'close' log can't be emitted (kill -9, system
crash, etc.), or if the 'open' and the 'close' log are several
hours, days or months appart.
An additional field "duration" has been added to the 'close' logs,
this represents the number of seconds (with millisecond precision)
the connection lasted.
Two new fields "globalsql" and "accountsql" have been added to the
'open'-type logs. These will contain either "ok" if we successfully
logged to the corresponding log database, "no" if it is disabled,
or "error $aDetailedMessage" if we got an error trying to insert
the row. The 'close'-type log also has the new "accountsql_close"
field, but misses the "globalsql_close" field as we never update
the global database on this event. On the 'close' log, we can also
have the value "missing", indicating that we couldn't update the
access log row in the database, as the corresponding 'open' log
couldn't insert it.
The "ttyrecsize" log field for the 'close'-type logs has been removed,
as it was never completely implemented, and contains bogus data if
ttyrec log rotation occurs. It has also been removed from the sqlite
log databases.
The 'open' and 'close' events are now pushed to our own log files,
in addition to syslog, if logging to those files is enabled (see
``enableGlobalAccesssLog`` and ``enableAccountAccessLog``), previously
the 'close' events were only pushed to syslog.
The /home/osh.log is no longer used for ``enableGlobalAccessLog``, the
global log is instead written to /home/logkeeper/global-log-YYYYMM.log.
The global sql file, enabled with ``enableGlobalSqlLog``, is now
split by year-month instead of by year, to
/home/logkeeper/global-log-YYYYMM.sqlite.
Under FreeBSD, users can't read /etc/spwd.db, and there is no helper
for pam_unix.so to validate user passwords, as this is the case under
Linux, so we have to launch pamtester under root so that pam_unix.so
can do its job
