Looks good!
Using 1.4.4, compiled the 09/27 patch on an u3 system and ran on
u4 system. Compiled the 09/28 patch on the u4 system (source
in AFS) using the cache manager from the 09/27 patch.
Installed the 09/28 cache manager on the u4 and it too is running.
(still to test is running the u4 built version on a u3, and building
on 5.8 and 5.9 just to make sure they still run.)
The u3 system is: 5.10 Generic_125100-10 sun4u sparc SUNW,A70
The u4 system is: 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-280R
P.S.
Built the aklog using the u4 provided /usr/include/kerberosv5/krb5.h
and it runs on both the u3 and u4 systems.
To build aklog required this patch:
http://www.openafs.org/dl/openafs/1.4.4/sun4x_510/aklog-solaris10-krb5.diff
(This is in the CVS but not part of 1.4.4.)
The build was done using:
KRB5CFLAGS="-I/usr/include/kerberosv5"
KRB5LIBS="/usr/lib/gss/mech_krb5.so -R/usr/lib/gss"
export KRB5CFLAGS
export KRB5LIBS
./configure --enable-transarc-paths \
--with-krb5=yes \
--enable-namei-fileserver \
--enable-largefile-fileserver \
--host=sparc-sun-solaris2.10

Here's a candidate patch for those of you running any version of
Solaris 10, or have hopes of running OpenAFS on Solaris 10 8/07
(update 4);
This patch removes use of the non-Public ILL structures by OpenAFS to
gather network interface information in order to make RX packet size
and server locality decisions. I replaced it with a Solaris taskq(9f)
that executes a function which polls the network interfaces on the
machine and populates a global array with collected information.
Network information consumers then walk this array to gain the info
they require. This polling function, by default, runs every 30 seconds.
I made a design change from previous versions in that I dispensed with
the while(1) loop for the polling mechanism. The osi_NetIfPoller
function now chains itself.
The interval between polls may be adjusted either by /etc/system or in
real time by the use of mdb:
Set afs interface poll interval to 15 seconds using /etc/system:
set afs:afs_if_poll_interval=15
Get current poll interval using mdb:
# echo afs_if_poll_interval/D | mdb -k
afs_if_poll_interval:
afs_if_poll_interval: 30
Set a new poll interval to 15 seconds (in hex):
# echo "afs_if_poll_interval/W 0f" | mdb -kw
afs_if_poll_interval: 0x1e = 0xf
You may see if the poller is doing its job by watching the "executed"
line of the afs_taskq kstat:
# kstat -n afs_taskq
module: unix instance: 0
name: afs_taskq class: taskq
crtime 141.142208577
executed 126
maxtasks 1
nactive 2
nalloc 0
priority 60
snaptime 2286.25972396
tasks 126
threads 2
totaltime 28790720
The following patch applies against OpenAFS 1.4.4. I urge that it be
tested on any version of Solaris that you may have at your disposal,
not just 10u4. Please discuss any issues on the -devel list.
