Linux 3.0 Release Delayed 187

Posted by timothy from the wait-for-it-wait-for-it dept.
JustinRLynn writes "A recent Google+ Post by Linus Torvalds indicates that version 3.0 of the Linux kernel will have to wait due to the discovery of a 'subtle pathname lookup bug.' Linus indicates, 'We have a patch, we understand the problem, and it looks ObviouslyCorrect(tm), but I don't think I want to release 3.0 just a couple of hours after applying it.'"

          Simple enough, Firefox style: Any time you get a semi-clean build, you tag it. When you release, you simply bump the version number of the last tagged build. So what if you don't get half the features - it's a new version, as witnessed by the version number!

      Makes sense to me. Unlike Facebook, G+ allows anyone with an account to follow Linus's public posts without him having to accept them as his "friends".

      It's perfect for this type of announcement. It's Twitter for those who felt constrained by the character limit.

        I noticed within a couple days that the posts on Google+ weren't similar to my Facebook news feed, they were identical to my Twitter feed.

        Google+ blows the doors off of Twitter and it accomplishes the same thing. It is built around the "Follow" philosophy instead of the "Friend" philosophy.

        As a consequence I don't think people will feel safe and private on Google

      I don't know what commercial environment you've been in, but in the places I've worked, release becomes hell because you have your bug list and someone (read a commitee) has gone through and labeled the "show stoppers" which are bugs deemed important enough to be fixed before the software can be released, and because of politics in the commitee, all but the most trivial become show stoppers.

        That depends on the balance of power in the organization. If sales/marketing have the bigger share of the power, QA is downsized or eliminated and the only "show stoppers" are unchecked feature boxes.

      • On some organizations all that process happen after some manager already sent the software to packaging, so you'll have an update before even the release.

        Of course, on other organizations both precedures run in parallel with some requisite changes. Those are the fun ones to work in.

      Ok, from my reading of the patch which could be WAY the fuck wrong BTW, I think it is a race condition between the unlinking of a file and returning the inode to the pool AND the CP command ( copy a file ) traversing the inode list. In other words the CP command was trying to stat a file that was partially unlinked do to the update of the node list still being in progress.

      If you still don't understand that don't feel bad, I had to read and re-read the note like 10 times before I probably got this explanation wrong.

        And I think you're wrong, there's no "rm" involved.

        The removal is that the file details are being cleared from the memory cache and the cp is only looking in the cache for something it knew was there but hasn't locked yet. Because it wasn't locked another thread though it was a good candidate to be removed from the cache. The cp then assumed it was gone because something physically deleted it.

      The solution to this is really Obviously Correct; I don't know why they didn't post the bug in the summary:

      That -ENOENT in walk_component: isn't it assuming we found a negative
      dentry, before reaching the read_seqcount_retry which complete_walk
      (or nameidata_drop_rcu_last before 3.0) would use to confirm a successful
      lookup? And can't memory pressure prune a dentry, coming to dentry_kill
      which __d_drops to unhash before dentry_iput resets d_inode to NULL, but
      the dentry_rcuwalk_barrier between those is ineffective if the other end
      ignores the seqcount?

  • I bet this mysterious bug is actually caused by a build script trying to pry source code from the bottomless pit of horror that is Git. One could qualify that as an "incredibly subtle pathname lookup bug"...

    For everything besides committing, Git is horrible. This thing is actually making SourceSafe looks trusty and convenient.

    Now that the world is running on Linux (except for MySpace and GoDaddy) it is a crime to impede its evolution by using such a painful system. Down with Git, and long live Anything Else

      It can take time for some people to get used to git ("wait the commands aren't exactly the same as CVS!? noooooooooo...").

      But once it clicks, you'll never want to go back.

      There's a good reason git is by far the most popular "new generation" source-control system (and no, it's not "because Linus is popular"). It's simply more powerful, more facile, more nimble than the competition.

      It would be nice to know what you had a problem with. People here could perhaps enlighten you as to why things aren't working out for you, or you could enlighten them as to why git is inferior.
