BSDCon '03 Nearly Here (OpenBSD 3.4, Too) 332

Posted by timothy from the such-euphony-from-three-little-letters dept.
robotdreams writes "Once again BSDCon showcases the BSD community's long history of innovative research, open exchange of ideas, and collaborative work. Tutorials this year feature: an intensive code walkthrough of the new FreeBSD 5.x release, debugging kernel problems on live systems, advanced BSD system and network security, and FreeBSD's new GEOM disk I/O subsystem." Since BSDCon runs from September 8th through 12th, you're probably either already going or out of luck ;) On the other hand, you're still early for OpenBSD 3.4, now taking pre-orders -- details below.

An anonymous reader writes "Pre-orders for the OpenBSD project's latest release, 3.4, are now being taken. This release will ship around November 1st. Significant enhancements have been made in this release, including i386 switch to ELF executable format, further W^X improvements for i386, ld.so on ELF platforms now loads libraries in a random order for greater resistance to attacks, inclusion of a static bounds checker to the compiler for basic checks on functions which accept buffers and sizes, strcpy/strcat function audit to replace with safer strlcpy/strlcat, ProPolice stack protection in the kernel, further manual page cleanups, large number of bug fixes and optimizations to the packet filter (PF) including packet tagging, stateful TCP normalization, passive OS detection, SYN proxy, and adaptive state timeouts, and many other improvements to the rest of the system.

Order a CD from the OpenBSD store. Ordering a CD helps support the project, as a bonus you get cool stickers, artwork, and an audio track!"

The same reader sent links to more information on this release, including new features, and the changelog between 3.3 and 3.4.

          First of all, there has been a _small_ bit of interest in Tendra by just a few in the BSD community, but I don't think it's fair to say that they have been looking into replacing GCC.

          Secondly, licensing isn't the only concern. An upgrade from GCC 2.9 to 3 is on the horizon, and at least one of the primary OpenBSD developers has said that they aren't happy with GCC 3. I don't think it's worth getting into detail, but it isn't licensing issues alone.
      • Anyone know why OpenBSD is removing GNU tools ... other than the licensing issues ?

        While I'm greatful I have these tools for free, and they have served me well, they are not without brain damage. For example, I found to my horror that 'patch' will, under certain circumstances, seek out and change my original files used to generate a patch, instead of what a reasonable reader would think to be the target files (the ones marked with "+++"). This is in fact documented behaviour, presumably thought to be go
      • licensing, less gpl is always better if possible. we also now maintain the tools entirely ourselves. cleanliness -- they don't even know how to indent properly. :) in the case of grep, it was a major improvement in size of the binary (think floppy installs) because we use libc regexp, not 3 different special edition text searchers made just for grep.
        • Actually, I was the original author of FreeGrep, and even if you pull out the text searchers in GNU Grep, FreeGrep is still only 1/3 the size (source lines).

          FreeGrep is also FAR more extensible and, in general, better designed. It would not be difficult to add support for grepping bzipped files, other compressed types, or even new types of files. It's also easier to add new options and features, though I do think the entire alphabet has been exhausted.

    I keep hearing that FreeBSD has a kickass filesystem. Is it more reliable than ext[2|3]? Because frankly, I think Linux filesystem is not all that great.

      So anyway, how does FreeBSD's filesystem stack up against Linux?

      FreeBSD chose to address this problem by making fsck capable of running in the background. fsck cooperates with the kernel, checking all files/inodes, and when a file is requested that has not yet been checked, the file operation is held while that check is moved to the front of the unique "moustache ride-ordered" queue.

      Journaling without sacrificing performance and clean algorithms simply isn't possible, and corruption is still possible on a journaling filesystem with out-of-order writes as done by many kinds of cache-enabled drives and controllers, leading to a false sense of security when fsck is bypassed. FreeBSD's approach catches every situation, and guarantees an intact filesystem on every boot.

        I dunno, have you see the previous article [slashdot.org]? I'd like to see FreeBSD catch this [datadocktorn.nu]!

          That the FreeBSD filesystem blows the above away is one of its greater strengths. Sun is the only UNIX with a faster filesystem, but at nothing like the price point of course.

          There's a reason why FreeBSD and Solaris are the only platforms where Oracle doesn't require a dedicated partition to create its own database filesystem. FreeBSD and Solaris can hack it. JFS, XFS, Reiser and friends are a fairly distant second.
