Hi,
The IPVS patch v0.8 for 2.2.12 is available at
http://www.linuxvirtualserver.org/ipvs-0.8-2.2.12.tar.gz
The changes are as follows:
- Added the persistent port feature.
Users can specify whether the virtual service port is persistent or
not. It is more flexible. The original PCC scheduling is removed.
- Added the dest server status checking.
The server status is checked before forwording a packet. If the
server is not available(down or put out of service), the packet
will be dropped and the client will be notified immediately.
The server status is also checked while generating a masq entry
based on the masq template. If not available, the new entry won't
be created.
- Added some code in ip_masq_ftp.c to handle virtual FTP service for
VS-NAT. The passive handling code in ip_masq_ftp.c never works.
- Fixed stepping to mSR after SYN in INPUT_ONLY table.
Thank Julian Anastasov for doing it. It make much much harder that
a LinuxDirector is synflooded to run out of memory.
- Fixed huge masq expire bug for after bad checksum.
Thank Julian Anastasov for fixing it.
- Added the IP_MASQ_F_VS_INACTIVE flag and fixed the connection
counter
Thank Julian Anastasov for the suggestion and fix example.
- Fixed the incorrect lookup in hash table.
The ms=NULL statement was forgot if no entry is found, this makes
the incorrect lookup, which may lead to huge masq expire.
Stupid mistake, but the result is serious.
- Fixed the incorrect slow timer vector layout
Correct layout and more efficient to use memory.
- Fixed the bug of slow timer being added twice for masq template
Note that I don't get time to fully test this patch. Please let me
know if there is any problem. Thanks!
Enjoy,
Wensong
BTW, the lvs-users@xxxxxxxxxxxxxxxxxxxxxx doesn't work very well
now. So, we are not hurry to move the mailing list now. Lars
is going to use qmail+ezmlm to run the list. We move to it later
after it works well. Thanks!
