There is no warranty that this cannot happen. Indeed, it has already
happened and will probably do again. A backdoor was found in some code
introduced in the bitkeeper repository, but it was noticed almost
immediately. Nobody has a full knowledge on the kernel today, but there
are *many* people with complementary knowledge, with experts in every
area. All code gets reviewed by hundreds of eyeballs all the time, and
such events might happen from time to time, with fixes proposed by other
people as soon as they get discovered as simple bugs or vulnerabilities.
The only way for such attacks to be effective would be to introduce
thousands of them, in the hope that one of them would not get noticed.
But do you think that kernel gods would accept to be fed patches very
long if this happened ? I don't think so. There already are discussions
about a cleanup step on current code while no backdoor seems to be in
the air.
In the hope that I have reassure you,
Willy
