Bug#403426: cryptsetup/linux-image-2.6.18-3-ixp4xx buglog divergence

2007-01-08 Thread Paul TBBle Hampson
Just poking around for low-hanging RC fruit...

This bug appears to me to have split into three
seperate bugs:

cryptsetup bug, when given bad data upgrade-header code corrupts header
This seems to be serious, and the point of #403426
On the other hand, if this bug only triggers when the kernel page
caching gets boned, it's probably not serious against cryptsetup,
but is the fault of the next bug.
Either way, fixed by the changes in rev20 upstream SVN, or the
1.0.5 release.

linux-image-2.6.18-3-ixp4xx bug, LUKS (and FUSE?) triggers page-cache
corruption.
This one seems critical, but has known fixe in
flush_anon_page-generic.patch and flush_anon_page-arm.patch in
debian-kernel SVN.

linux-image-2.6.18-3-ixp4xx bug, LUKS (but not FUSE?) fails to mount
under heavy load.
This seems less than serious (it's not actively corrupting data from
what I'm reading in the buglog) but prolly should be a seperate
bug for tracking purposes.

Anyway, from the looks of things there ought to be three seperate bugs
here, #403426 against cryptsetup, maybe downgraded and two against
linux-image-2.6.18-3-ixp4xx one critical (making an entire partition
unusable) and one important)

This would mean that cryptsetup is not unneccsarily RC, and the
critical data-corruption bug in linux-image-...-ixp4xx _is_ both
visible and appropriately RC.

Obviously it's submitter's and maintainer's calls, and I've already done
one impossible^wstupid thing before breakfast today with the BTS control
bot, so I'll just leave this here as a suggestion.

On the other hand I am glad now I didn't bother setting up LUKS on the
slug I built last week...

Well, I doubt it's worth at this stage to worry about which bug should
be RC or not.  I think it's pretty clear the cryptsetup maintainer
should upload a fixed package with the two patches from SVN which I
sent to #403426 already.  And the next upload of linux-2.6 will have
the fix for the 2nd item in your list.

This leaves the last problem (FUSE under load) which I think we can
leave for after etch.
