It's more complicated - some parts are completely different, some
backported from WebKit, some code is the same line-by-line, some rewritten.
But with every WebKit's CVE we are trying to reproduce it in KHTML and if we
can't reproduce it, we try to do a code review together with security response
team.

Some issues
are really toolkit-specific but from my observations - most of bugs applied on
all WebKits.

CVEs are usually fixed upstream but still you have
to go through all bugs and check it in all WebKits implementations (snapshot
revisions could help of course). WebKits shipped by Fedora usually differs -
different snapshots (but not big changes).

There's quite a big mess on WebKit's
security list, Vincent suggested few changes, let's see. Another question is
how to make releases in sync - to have same snapshots in Fedora.

outlining the idea of splitting/merging.
Any merging is really upstream
(upstreams) problem but yes - we need to clean up WebKits situations - what we
really have, who is consumer of which one etc.

Great (and yes, latest WebKits crashes - icedtea plugin is
cross WebKits one)!
