A couple of days ago, we noticed the following message appearing in syslog: Aug 14 15:09:35 zadok smbd[16067]: tdb(/var/lock/samba/locking.tdb): expand_file write of 8192 bytes failed (No space left on device) Similar messages would show up for several of the files under /var/lock/samba. Running df showed that /run/lock was full. Not having ever paid any attention to /run/lock before, I tho...

Hi, I'm working with Prof. Zadok on versionfs, a stackable versioning file system. I face some problems with the unlink operation on ext3 with htree. On an unlink, I make a copy of the file (version/backup) and unlink the original file. But some files that have been unlinked are "linked back" to another file. For examp...

Dear all, I am planning to add some cryptographic properties (file encryption and digital signature on file I/O) to Linux filesystem. In detail, I want that user can do file I/O with encrypted files like he used to do with usual file except some minor changes (e.g. supply key for decrypting file). For digital signature, all read and write acts on file of any user must be signed and recorded so

Hi Ted and all, I have a couple of questions near the end of this message, but first I have to describe my problem in some detail. The power failure on Thursday did something evil to my ext3 file system (box running RH9+patches, ext3, /dev/md0, raid5 driver, 400GB f/s using 3x200GB IDE drives and one hot-spare). The f/s got corrupt badly and the symptoms are very similar to what Eddy described

...flow security problem in the amd daemon which is part of the am-utils package has been fixed. This problem is being actively exploted on the Internet and can be used to gain root access on machines running amd. Red Hat recommends anyone to upgrade to the fixed versions immediately. Thanks to Erez Zadok, the maintainer of am-utils for his assistance in resolving this problem. 8. Solution: For each RPM for your particular architecture, run: rpm -Uvh <filename> where filename is the name of the RPM. 9. Verification: MD5 sum Package Name - -----------------------...

Hi, we're working on a stackable versioning file system for 2.4.x. Versioning can easily create lots of files for a file that gets modified frequently, and our current design puts all versions of a file in the same directory as the main file. We are therefore evaluating how stable and efficient different combinations of file systems would be in this scenario. We've run our versionfs on
