Version 1.1.1 of Chiron FS

Release Notes: This release has an option that allows it to mount a pseudo-filesystem (like /proc) to control the behavior of the Chiron filesystem being mounted, allowing it to show and change the status of the replicas. Dynamically generated Nagios plugin scripts are also provided. The howto and man page were updated. A a bug that made ChironFS fail to determine the correct path to the program that manages its control filesystem has been fixed.

Release Notes: This release integrates patches porting ChironFS to FreeBSD and NetBSD, and changes the debug code on *BSD versions to get the same system information that the Linux version gets. It is needed because the next ChironFS release will need that info in order to resynchronize failed replicas.

Release Notes: A vulnerability where an unprivileged user was able to touch a file which it did not have the rights to write was fixed along with a readlink bug where the number of bytes of the linked filename was being incorrectly reported. An issue in function access where the ruid and rgid of the caller process was not checked, but rather that of the mounting user was fixed. A memory leak was fixed.

Release Notes: A vulnerability has been fixed where files created a user other than the user that mounted ChironFS were owned by the mounting user and not the file creator. An experimental fix for a failure to exclude all files when doing massive delete ("rm -Rf" on directories with thousands of files). A bug that prevented using logfile-relative pathnames has been fixed. A prioritization system has been implemented, modifying the simple round-robin that made the load balance on read operations, and improving performance when some replicas are significantly slower than others. A memory leak has been fixed.
