Hi folks,
Just take time last night to push pending patch :)
Will submit a new release later on this month to add full v6 support for
IPVS part (it seems v6 is growing up ;))
ChangeLog for this release looks like :
2010-12-08 Alexandre Cassen <acassen@xxxxxxxxxxxx>
* keepalived-1.2.1 released.
* Vincent Bernat <bernat <at> luffy.cx>:
VRRP: Fix incorrect computation for packet size
* Vincent Bernat <bernat <at> luffy.cx>:
VRRP: handle passwords up to 8 characters
* Vincent Bernat <bernat <at> luffy.cx>:
When updating weight, check quorum state.
MISC check can update the weight of a real server. This
can lead to a change in quorum state.
We factor out quorum handling from perform_svr_state()
into a new function update_quorum_state() that will check if
the quorum state changed and if yes, update sorry server
status,
exec quorum commands and add back or remove alive real servers
(with existing function perform_quorum_state()).
This patch is mostly cut'n'paste and adding a call to
update_quorum_state() in update_svr_wgt(). We also make
perform_svr_state() and update_quorum_state() almost
symmetric.
* Vincent Bernat <bernat <at> luffy.cx>:
Fix an infinite loop in master transition with sync groups.
This patch is from Arjan Filius. See:
http://marc.info/?l=keepalived-devel&m=128212278218825&w=2
When transitioning to master state, keepalived might try to
force transition to master state of other VRRP instances into
the same group before their transition is complete. This leads
to an infinite loop with huge VRRP trafic.
* Vincent Bernat <bernat <at> luffy.cx>:
VRRP : Use VRRP_PRIO_DFL instead of 100 for default priority.
* Vincent Bernat <bernat <at> luffy.cx>:
Use netpacket/packet.h instead of linux/if_packet.h to get
sockaddr_ll.
linux/if_packet.h pulls linux/types.h that should not be used
by a userland program since types defined here can conflict
with stdint.h. We use netpacket/packet.h which is a GNU LibC
header.
* Vincent Bernat <bernat <at> luffy.cx>:
Keep current weight on reload when initial weight is not
altered.
Weight can be changed by MISC_CHECK when using dynamic option.
In case of reload, the change is lost until the script runs
again. We record the initial weight in a separate variable and
use it to check if a real server has changed instead of using
the actual weight.
* Vincent Bernat <bernat <at> luffy.cx>:
VRRP : disabled scripts and initially good scripts should be
considered as OK.
When a script is not weighted, its failure will lead to a
failure of the associated VRRP instance. However, disabled
script and scripts that are initially good (after a reload)
should be considered as successful and not make the instance
fail. Moreover, a disabled script should not be used when
computing script weights.
* Vincent Bernat <bernat <at> luffy.cx>:
VRRP : more informative message when disabling a script due
to use of weights.
When using a weight for a tracked script, the script is
disabled. However, the warning message said that the weight
was ignored. We change the message to tell that the script is
ignored. Moreover, we don't change its weight since it can be
used in another instance, not in a SYNC group.
* Vincent Bernat <bernat <at> luffy.cx>:
check : include missing virtual server group name in a log
message
* Vincent Bernat <bernat <at> luffy.cx>:
configure: add a check for ETHERTYPE_IPV6.
ETHERTYPE_IPV6 defined in net/ethernet.h is pretty recent.
If absent, we hard-code the value into CFLAGS. This patch
requires regeneration of configure.
* Vincent Bernat <bernat <at> luffy.cx>:
check : update server weight in IPVS only if server is alive
and in the pool.
With inhibit_on_failure, a server can be in the pool and not
alive. We don't want to set the weight of an inhibited server
or a server in a virtual server whose qorum is not met yet.
* Vincent Bernat <bernat <at> luffy.cx>:
check: really add back inhibited server when quorum is gained
A previous change contained an erroneous check to add back
alive servers when quorum state was gained. This check was
incompatible with inhibit_on_failure. When servers were added
back in the pool, the weight was not updated accordingly.
* Vincent Bernat <bernat <at> luffy.cx>:
check : update server weight despite quorum when no sorry
server.
In absence of a sorry server, the logic is to not use quorum
except to run commands when quorum is gained or lost. This
means that if a MISC check modifies the weight of a server
and there is no sorry server, we do not consider quorum.
Cheers,
Alexandre
