The patch was accepted upstream as is. I'm guessing no one cares about having the fix in oneiric at this point (I don't).

So where does this leave the patch? I'm not running oneric. Does this make precise or does a new bug report need to be created on precise? I will have precise installed here shortly and can have a look at it then. Just not sure where it goes from here. I'm willing to re-rent the movie and check it again, however if I need to repeat the process with precise, then I'll file and wait for verification-needed state there before renting.

@ricky, huh didn't see your comment #9 until now. Totally understand not wanting to be on too many lists (I feel the same). However I've found this one to be reasonable (couple emails a week). In any case I don't really mind forwarding patches there myself and so can take care of that end.

Anyway, looks like the sru for oneiric has already been uploaded. natty is pretty long in the tooth so not really worth SRUing that. So I'm going to close out this bug.

Hi Vibhav - Thanks for the debdiff! Unfortunately, there are a few issues. I don't think you truly meant to subscribe ubuntu-security- sponsors, since you targeted the oneiric-proposed pocket. If you did intend for this to go to the security pocket, use oneiric-security in the changelog. Otherwise, you probably wanted to subscribe ubuntu- sponsors. Either way, there is a bigger problem here. 103-iforead-tt-srpt- pointerfix.patch didn't make it into the debdiff.

[Bug 894170] Re: libdvdread core dumps with invalid next size
Trouble is, I get too much mail as it is. I'll just continue to carry on as I have - I get 2 new movies a week, so I go through a pretty fair selection of trouble makers, and so far, I've got a good system that uses a script that uses a combination of things - HandbrakeCLI,mplayer, vlc, vobcopy, ddrescue, and dvdbackup, though I primarily use mplayer Handbrake - the former to rip, the latter to find the correct title - all just to watch a stupid movie. I'm considering releasing it on sourceforge - but it's an awful effort to get all the source patched and built, which has to be done or the script doesn't do much. So I'd have to do a build system, which takes time and is painful. Though I guess if I released i386 and amd64 debs, it would get the majority of the crowd. I never would have gone down this path if those idiots hadn't pissed me off several times when I had to spend a couple hours trying to just play a movie I legally rented, so now I fix every glitch I discover, and make sure someone gets the patch for the world at large. It's astounding at how devious and fruitless their efforts are - and I will continue to fight with my vote and my code, but truly, I've got to have a mis- behaving movie, and I haven't come across one since this last fix, so not sure what being on the mailing list would do us - besides filling my inbox. I don't have time right now to go rent troublesome movies, so I think this mode will work for now. Besides, I've seen patches on mplayerhq that sat there for months, with various people wondering why they bothered. I know this is a pain for you, since you have to maintain the package, and it would be easier to submit to *hq, but maybe we're good for a bit - until the next desperate, brain dead attempt surfaces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/894170 Title: libdvdread core dumps with invalid next size To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdread/+bug/894170/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 894170] Re: libdvdread core dumps with invalid next size
rickyrockrat, yeah I tested against 4.2.0 which also includes a fix for Thor, but implemented differently than the patch we put in Ubuntu. That could be why the error I saw was so different than what you saw. Still, the DVD segfaulted for me as it had for you, and your patch (with a couple tweaks) made it not crash. I would agree with you that there's more work needed, and an onion is a good analogy. I've forwarded the patch upstream and will follow up on any improvements they can suggest.
