The 25-Year-Old BSD Bug

Posted by Soulskill on from the better-late-than-never dept.

sproketboy writes with news that a developer named Marc Balmer has recently fixed a bug in a bit of BSD code which is roughly 25 years old. In addition to the OSnews summary, you can read Balmer's comments and a technical description of the bug. "This code will not work as expected when seeking to the second entry of a block where the first has been deleted: seekdir() calls readdir() which happily skips the first entry (it has inode set to zero), and advance to the second entry. When the user now calls readdir() to read the directory entry to which he just seekdir()ed, he does not get the second entry but the third. Much to my surprise I not only found this problem in all other BSDs or BSD derived systems like Mac OS X, but also in very old BSD versions. I first checked 4.4BSD Lite 2, and Otto confirmed it is also in 4.2BSD. The bug has been around for roughly 25 years or more."

      that's funny, since Microsoft has used gobs of BSD code over the years

      Of course. Because they keep 25 year old bugs as compatibility features, while we break compatibility and fix them.

    but they had more important things to do. At least until Balmer started throwing chairs.

      At that point they had far more important things to do.

      Such as dodging chairs.

    Of course, now that I've R'd the FA, I understand that it's the first entry in the block (of which a directory with a sufficient number of files would have multiple), and not the first entry in the directory. Kindly ignore my previous response... Nothing to see here...

      In comparison, Microsoft has been around for what... 20 years? And who knows what bugs in Windows are there, lurking, just waiting to bite us? Microsoft was founded in 1988?!

    If no one has cared enough to fix it for 25 years, I'm guessing this should be rated as "inconsequential."

    3 thoughts on this:

    1. I think this bug would be classified "archeological".

    2. The question now is what happens to the Samba work-around patches. Now that the bug is fixed, do the patches cause a side-effect (i.e. "a new bug")?

    3. This gives rise to a new meme of nerd insults. "You call yourself a programmer? Why I've fixed bugs older than you!" Of course, only one man is entitled to use that line.

    No, this story proves that BSD is dying because there was a bug in it and no complaints were heard for 25 years.
