The utilities have certainly matured enough to earn the 1.0 moniker. This release is fixes the internal issues that broke running 32 bit utilities on 64bit systems, and fixes scaling issues. The tarball can be downloaded from: http://prdownloads.sourceforge.net/bridge Changes: - Uses sysfs for bridge and port parameter changes. - Uses new ioctl's for add/delete bridges and interfaces that are 32/64bit compatible. - Allows 1000's of interfaces in a bridge. - Performance improvement with lots of bridges/interfaces - Better error handling - More complete configuration and build Getting full functionality requires a build system with: - libsysfs from the sysfsutils package http://linux-diag.sourceforge.net/Sysfsutils.html - kernel (and headers) from 2.6.7-rc1 or later Note: libsysfs has not been fully integrated by the main linux vendors. So producing a full functional package is not possible with the default spec file. The utilities will build (and run) on earlier systems it will just default to the old interface and which doesn't have 32/64 bit compatibility. The API in libbridge changed, because it didn't scale to lots of interfaces. Previously, the library would read the status of all bridges and interfaces when initialized. The new interface takes names (not objects) and looks more like syscalls. Since libbridge is shipped as a static library, it will not break binary utilities, but anything compiled from source would break. Not a big issue because there is no existing standard package using the bridge API anyway.
