Linux 2.6.18 break scratchbox

Linux 2.6.18 break scratchbox

[koos vriezen]

Hi,
Hit by http://bugzilla.scratchbox.org/bugzilla/show_bug.cgi?id=279 I
wondered why such
a change that could break existing setups entered 2.6.18.
Now I can peek through '/proc/<pid of process outside chroot env w/ my
UID>/root' into the
box's root (and that's why scratchbox is broken now).
Regards,
Koos

File bug at bugzilla.kernel.org :-).

I'm afraid we did not know about this ABI change, and noone using
scratchbox tested 2.6.18-rcX...

Well I did google for this before this report and eg.
http://nchip.livejournal.com/ already mentioned it (but probably
didn't report it at lkml) and there where some other links.
But since I couldn't find any info on this new feature, that one can
now read and write file through the /proc/xx/root link, I ask it here.
And hopefully, if it's a regression, would be fixed in the stable tree
ASAP. (Somehow I almost can't believe this change wouldn't show
immediately in a regression test setup, and there must be a reason for
opening this door w/o using an axe).

You probably want to do that bugzilla.kernel.org... and yes, this is
kind of bug I can imageine goes in without anyone noticing.
