alpha/ia64/x86 stable, thanks Markus.
Stable for HPPA.
ppc stable
I vote noglsa. Hard to exploit (needs other events). Not critical.
(In reply to comment #2) > net-dns/c-ares-1.4.0 > 1. emerges on x86 > 2. passes collision test > 3. net-misc/curl-7.15.1-r1 USE="ares" emerges with it Good test. I should of mentioned it. This was the test I did on amd64. Small thing is you need USE=-ipv6 for USE=ares to have an effect.
voting no too. The least significant 32bits of the nanosecond time should be hard to get even on the same shared machine. Predicting the next dns query after answering the previous one is probably hard (unless its to the same location where it doesn't matter).
Voting NO too. Sparc please test and mark stable.
sparc stable.
voting no too, and closing.
