           Summary: segfault when i386 client touches x86_64 server (no
                    rsh/ssh) both cvs 3.0.0 today 20070813
           Product: rsync
           Version: 3.0.0
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned@samba.org
        ReportedBy: brian@aljex.com
         QAContact: rsync-qa@samba.org


built rsync 3.0.0cvs on two machines today, 20070813

machine A, server, suse linux 10.2 x86_64
Linux bu1 2.6.18.8-0.5-default #1 SMP Fri Jun 22 12:17:53 UTC 2007 x86_64
x86_64 x86_64 GNU/Linux

machine B, client, suse linux 10.2 i386
Linux slosh 2.6.18.2-34-default #1 SMP Mon Nov 27 11:46:27 UTC 2006 i686 i686
i386 GNU/Linux

on both machines the ./configure command used was:
./configure --disable-debug --disable-ipv6 --prefix=/usr CFLAGS="-O2"

Both built without apparent error and both run without error at least locally.
That is,
* both run "rsync --version" with no error
* both can rsync local files

Server A:
* is running rsync --daemon
* is a backup/install server for my company and lots of machines hit it all the
time both downloading and uploading. It's been doing fine all day running
the
new binary.
* the clients that hit this are all using rsync 2.6.9 or older, mostly SCO Open
Server 5.0.[4567] i386 and Suse linux 9.x 10.x i386 & x86_64

Client B:
* new binary ran a 300 gig local rsync job from local raid array to local
external usb drive with no problem. (empty drive so 300gb transferred, plus
updates later also no problem)
* only segfaults when trying to do a network rsync, specifically:
export USER=foo RSYNC_PASSWORD=foo
rsync -av --del install.aljex.com::${USER}/foo/data /foo
* segfaults immediately, no other messages, no time at all spent, say, looking
at local files to build the list.
* rebuilt with just ./config --PREFIX=/usr  no change
* built 2.6.9 with ./configure --disable-debug --disable-ipv6 --prefix=/usr
CFLAGS="-O2" and the network rsync works perfect again.

Didn't try other possible debugging tests yet like trying with rsh or ssh
instead of direct, or generating debug trace, or trying 3.0.0 to 3.0.0 where
both server & client are the same platform or perhaps the same box even. or
the
reverse of what I tried, x86_64 3.0.0 client accessing i386 3.0.0 server.
Can try all that a little later.

There was a bug I had introduced a few days ago in daemon mode.  I just
checked-in a fix, so this should be fine in the latest CVS (and latest
"nightly" tar file).
