Bug#415952: openafs-client: klog fails with an bus access error for password longer then 8 symbols.
Russ Allbery schrieb: Okay, one more try at this. One of the other OpenAFS developers found a SPARC Linux box with AFS installed and spent some time tracking this down. Could you try this patch instead of all the previous patches I sent you (in other words, try applying it to a fresh copy of the source retrieved via apt-get source openafs) and see if this clears up the problem? Well, it seams to solve the key_sched.c problem. There is another problem with the following Backtrace: snip Starting program: /tmp/openafs-1.4.4.dfsg1/src/kauth/klog Password: stackcheck = 0: stack = 0 topstack = 0xffcfbb1c: stackptr = 0xf7c5a008: stacksize = 0x48000 Thu Jul 12 09:18:14 2007 LWP: stack overflow in process IO MANAGER!

Russ Allbery schrieb: Could you try this patch as well and see if it helps any? It's unfortunately less likely to help than the previous one, but it's possible that it's the issue. There's some weird gcc optimizer issue going on. This helps on Mac OS X, at least. I am afraid but this patch does not help either. The bus error happens at line 236 in src/des/key_sched.c 236 if ((unsigned)Key[(int)*kp++]) 237 temp |= (1 BIT(31)); Hope that helps, Marko -- Marko Rößler @ Chemnitz University of Technology _ _ __ / \ / \ | Phone (49) 371 53133590 \_ \_ |_ Fax(49) 371 531833590 \ \ | Mail [EMAIL PROTECTED] \_/ \_/ |__WEBhttp://www.tu-chemnitz.de/etit/sse GPG1024D/F81F1B7F signature.asc Description: OpenPGP digital signature

I applied the patch, but unfortunately it didn't change the behaviour.

Sorry about the delay in responding. I've forwarded this upstream. It
looks to me like there may be some sort of alignment issue in the DES
library, although I'm not sure why this would just start happening now.
Can you try building with the following patch and let me know if it helps?

Bug#415952: openafs-client: klog fails with an bus access error for password longer then 8 symbols.
Hi Russ, finaly i managed to compile the openafs-client with debug symbols and received the following BackTrace: (gdb) run Starting program: /var/cache/apt-build/build/openafs-1.4.4.dfsg1/src/kauth/klog Password: Program received signal SIGBUS, Bus error. 0x0004a2a8 in des_key_sched () (gdb) bt #0 0x0004a2a8 in des_key_sched () #1 0x00012708 in ka_StringToKey () #2 0x00013f34 in ka_UserAuthenticateGeneral () #3 0x00012008 in CommandProc () #4 0x0004 in cmd_Dispatch () #5 0x00011b28 in main () Can i help any further?

Hm, it wasn't received, but it was possibly too large. A backtrace is more useful anyway. I am not shure how to create a backtrace. Can you please quickly point me the way out? Install gdb and then run: gdb /usr/bin/klog and then at the gdb prompt, type: run username where username is the username you're authenticating as. Enter the password that causes it to die, and gdb should catch the bus error. At that point, you should be able to type: bt to get a backtrace. -- Russ Allbery ([EMAIL PROTECTED]) http://www.eyrie.org/~eagle/ -- Please take notice of the new telephone number Marko Rößler @ Chemnitz University of Technology _ _ __ / \ / \ | Phone (49) 371 53133590 *new* \_ \_ |_ Fax(49) 371 531833590 *new* \ \ | Mail [EMAIL PROTECTED] \_/ \_/ |__WEBhttp://www.tu-chemnitz.de/etit/sse GPG1024D/F81F1B7F -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
