[OpenAFS] OpenAFS-Client crashes AIX 5.1

[Hans-Gunther Borrmann]

Hello all,

What I did:

I compiled openafs-snap-2005-01-17 under AIX 5.1with the following patch to 
rxkad.p.h, which defines the max ticket length as 344:

*** rxkad.p.h	2005-01-18 09:52:10.000000000 +0100
--- ./rxkad.p.h.orig	2004-12-07 17:49:11.000000000 +0100
***************
*** 17,23 ****
--- 17,31 ----
  #define MAXKTCTICKETLIFETIME (30*24*3600)
  #define MINKTCTICKETLEN	      32
  
+ #if defined(AFS_AIX52_ENV)
+ #ifdef __XCOFF64__
+ #define	MAXKTCTICKETLEN	      12000	/* was 344 */
+ #else
  #define MAXKTCTICKETLEN		344
+ #endif
+ #else
+ #define	MAXKTCTICKETLEN	      12000	/* was 344 */
+ #endif
  
  #define	MAXKTCNAMELEN	      64	/* name & inst should be 256 */
  #define MAXKTCREALMLEN	      64	/* should be 256 */

The call to configure is:

CC=cc ./configure --with-afs-sysname=rs_aix51 \
	--enable-namei-fileserver \
	--enable-largefile-fileserver \
	--enable-fast-restart \
	--enable-bitmap-later \
	--enable-tivoli-tsm \
	--enable-transarc-paths \
	--disable-pam

After the installation of this version on my test machine I started the 
client, got a token and tard my AFS home directory to /dev/null. After some 
time the system crashed. Crash information follows:
