Linux Virtual Server

Additional hash functions were included for IPVS
connection entries to prevent hash attacks. The
maximum value of the connection threshold was
changed from 65535 to INT_MAX (2147483647), the
default syncid was changed from 255 to 0, and
ip_vs_sync.c was updated for Linux kernel
2.5.74. Some code was also tidied up.

The slow timer indexes are now initialized
correctly. It is now possible to start the
master and backup sync daemons simultaneously,
and SyncID support was added for filtering
incoming sync messages. The method for
retrieving information about the daemons was
changed, and the 2.5.70 Linux kernel is now
supported.

The terrible piece of code which initialized the sltimer_jiffies with the system jiffies, which was added in version 1.0.8, was removed. The Shortest Expected Delay scheduling module and the Never Queue scheduling module were ported back from IPVS 1.1.5.

This release adds the Shortest Expected Delay and the Never Queue scheduling modules. It uses Linux kernel 2.5.69, and has an ipvsadm man page update.

ipvsadm has been updated to version 1.23 so that it can display the counter of persistent connections by "ipvsadm -Ln --persistent-conn". A counter of persistent connections per real server has been added. The overhead ratio of active/inactive connections has been changed from 50 to 256 in the least connection scheduler. The unnecessary Docdir setting in ipvsadm.spec.in has been removed.
