Hello Eric,
This fills a need I had to get the current TID in a Java program,
so I'm very interested in this change. OTOH, how will someone
not reading LKML discover that the current TID is now in
/proc/self and that it was not always the case?
I would put my 2 cents in /proc/self/task/self,

Unfortunately, I couldn't manage to reproduce the problem with an
unpatched kernel. But your investigation Ilpo was really impressive.
BTW, even though I messed up the yahoo webmail

I am Bittorrenting for a few hours with these patches, and they seem to
work well. Thanks for the quick response.

Just another data point, it seems that running the standard Bittorrent
client helps
, the added safety seems worth, but for IPv6 it's less clear.
Thanks.

Clear the accumulated junk in IP6CB when starting to handle an
IPV6 packet.

why does the input side of the ip layer believe the cb contains valid

Why not clearing the whole IPCB(skb) instead of
just IPCB(skb)-opts?
is a patch to
initialize cb later, and make it clear that initializing it sooner
is a bad idea.
[From Stephen Hemminger: leave cb unitialized in order to let gcc
complain in case of use before initialization]
Thanks.

Hello,
Is it a known problem that the Netem qdisc is very unreliable on the
loopback (unlike on a true NIC)?
This seems to come from its usage of skb-cb which conflicts with IPCB.
For instance, the field
IPCB(skb)-opt.optlen becomes non-null and memory corruption follows.
