I can smbmount a testshare and display its
content, but when trying to access the files, Samba panics.

This entry in the log concerns me.
send_file_readX: sendfile failed for file SS2.FieldServiceManual.pdf (Bad address). Terminating
It looks like the code sendfile is broken on this platform. I'll get someone from Sun to investigate.
- setting sendfile=no doesn't help
- 3.0.30 does work
Just tried on a box that says
SunOS sunX 5.10 Generic sun4u sparc SUNW,Sun-Blade-1000
and I could not reproduce this. Hmmm.
While compiling Samba 3.2.0 again, I just discovered
lib/sendfile.c: In function `sys_sendfile':
lib/sendfile.c:187: warning: cast from pointer to integer of different size
Does this ring a bell for somebody?

This is a backtrace of the process which paniced
I set 'panic action=99999' and ran
gdb /usr/sbin/samba --pid=<PidOfPanicedProcess>
I may be seeing the same issue. Samba 3.2.0 built using gcc 3.4.3 on Solaris 10 Sparc (SunOS techops 5.10 Generic_137111-02 sun4u sparc SUNW,Ultra-80) This server is a member server of Active Directory.

Can you try the attached patch?

That one looks different. Can you also provide a backtrace given the instructions here?

Thanks Volker, I applied this patch, but nothing
changed. Did you see comment #5 ?

Yes, I did see comment #5. This would only apply however if you have "use sendfile = yes" activated. Can you send a new backtrace with the patch applied?

OK, I just attached another backtrace made after I applied your patch.
I had to apply it by hand, btw. because 'patch -p3 <patchfile'
in source/locking didn't work.
What would have been the proper way to apply it?
Created attachment 3393 [details]
locking.c with the patch applied
Hmmm. What exact version are you running? I just tried to apply the patch, and it worked fine. I've attached the patched locking.c which comes from the 3.2.0 release.
use gpatch (GNU patch), I often saw Sun's patch fail to apply unified diff patches created by GUN diff (or by git, can't remember...)

Ah, thanks. That was it.
gpatch -p3 <patchfile
What does work? Could you apply the patchfile and it still dies, or does the patch cure your problem?
Pushed the fix. Thanks,
I'm very sorry having to reopen this bug, but it seems there's still some sendfile problems in 3.2.0:
While I can connect and browse shares ok, if i double click for example on a pdf file, Acroread starts but fails to open the document on the samba share.
send_file_readX: sendfile failed for file private/Arbeitszeitstatistiken/AZSt-2006.02.pdf (Bad address). Terminating
What can I do to help you find this bug?
Can you upload a new debug level 10 log with 3.2.1? The alignment-related patches went into 3.2.1, if there's a sendfile problem left we should catch that one now.
Here's the log created while running Samba 3.2.1
Doubleclicking on a PDF File from a Windows Client
yields an acrobat reader without an open file
This bug is still present in samba 3.2.7 on solaris 9 sparc.

did you solve the bug for you or are you working now with use sendfile = No?

> @Christoph Kaegi:

No, I didn't solve the bug. We still run Samba 3.0.30...
Just wanted to add, that this bug is still up and alive with 3.3.4.
I have to use "use sendfile = no" in order for the shares to work.
The errormessage in smbd.log is now:
[2009/04/29 13:55:02, 0] smbd/reply.c:send_file_readX(3279)
send_file_readX: sendfile failed for file print-2006.11/2006.03.06-171404.jpg (Bad address). Terminating
