An updated rsync package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The rsync tool is used to copy and synchronize files locally or across a network. The rsync works very fast because it uses delta encoding and sends only differences in files instead of whole files. The rsync is also used as a powerful mirroring tool.
- When creating a sparse file that was zero blocks long, the "rsync --sparse" command did not properly truncate the sparse file at the end of the copy transaction. As a consequence, the file size was bigger than expected. With this update, the underlying source code has been modified to ensure proper truncating of such files.
- Previously, the rsync utility could terminate unexpectedly with the following error during a data transfer:
Inflate (token) returned -5This happened if the block size was exactly of the size of the CHUNK_SIZE constant. The output buffer was completely filled after calling the inflate() function for the first time, and it was therefore not possible to obtain remaining buffer output when calling inflate() the next time. The Z_BUF_ERROR constant is now handled properly, and so prevents rsync from terminating in the described scenario.
All users of rsync are advised to upgrade to this updated package, which fixes these bugs.
Updated rsync packages that fix one bug are now available for Red Hat Enterprise Linux 6 Extended Update Support.
The rsync tool is used to copy and synchronize files locally or across a network. The rsync works very fast because it uses delta encoding and sends just differences in files instead of whole files. The rsync is also used as powerful mirroring tool.
- Previously, the rsync tool did not check whether the inbuf variable is non-empty. As a consequence, rsync terminated unexpectedly while trying to do the required encoding in a loop. With this update, rsync checks whether inbuf is non-empty and no longer crashes in the described scenario.
Users of rsync are advised to upgrade to these updated packages, which fix this bug.
