rsync segfaults
Last modified: 2014-03-16 22:25:09 EDT
The latest rsync errata segfaults when using the -z option. Without -z it spits out some warnings (the hdlist file is not the original one from 7.2): [root@soliton root]# rpm -q rsync rsync-2.4.6-8 [root@soliton root]# rsync -v -v -aze ssh /usr/src/redhat-7.2/RedHat/base/ tomcat:/usr/src/redhat-7.2/RedHat/base/ building file list ... done ./ comps is uptodate hdlist Segmentation fault [root@soliton root]# rsync -v -v -ae ssh /usr/src/redhat-7.2/RedHat/base/ tomcat:/usr/src/redhat-7.2/RedHat/base/ building file list ... done ./ comps is uptodate hdlist Warning: unexpected read size of 0 in map_ptr Warning: unexpected read size of 0 in map_ptr hdlist2 Warning: unexpected read size of 0 in map_ptr Warning: unexpected read size of 0 in map_ptr hdstg1.img is uptodate netstg1.img is uptodate stage2.img is uptodate total: matches=7188 tag_hits=1454663 false_alarms=221 data=7704563 ./ wrote 17741020 bytes read 118516 bytes 463884.05 bytes/sec total size is 80762845 speedup is 4.52
Do you have a reliable case that reproduces this?
Also, are the files that cause the warnings transferred correctly?
I did some further testing and I can reproduce it: [root@soliton tmp]# tar --use-compress-program bunzip2 -xf rsync.tar.bz2 [root@soliton tmp]# ls -lh local/hdlist2 remote/hdlist2 -rw-r--r-- 1 root root 15M Jan 26 12:02 local/hdlist2 -rw-r--r-- 1 root root 24M Jan 27 16:37 remote/hdlist2 [root@soliton tmp]# rsync -az local/ remote/ Segmentation fault [root@soliton tmp]# ls -lh local/hdlist2 remote/hdlist2 -rw-r--r-- 1 root root 15M Jan 26 12:02 local/hdlist2 -rw-r--r-- 1 root root 24M Jan 27 16:37 remote/hdlist2 [root@soliton tmp]# rsync -a local/ remote/ Warning: unexpected read size of 0 in map_ptr Warning: unexpected read size of 0 in map_ptr [root@soliton tmp]# ls -lh local/hdlist2 remote/hdlist2 -rw-r--r-- 1 root root 15M Jan 26 12:02 local/hdlist2 -rw-r--r-- 1 root root 24M Jan 26 12:02 remote/hdlist2 The file rsync.tar.bz2 is 11MB. Shall I upload it to bugzilla or put it on my ftp server so you can download it?
Just as a test, if you rebuild rsync, does it start working for you?
Please try: http://people.redhat.com/notting/rsync-2.4.6-9.i386.rpm
Yes, these packages seem to fix the problem. Thanks!
Same issue here, rsync between redhat 7.2 and 7.0, both with the new errata. Putting the 2.4.6-9 RPM referenced above onto the 7.2 box fixes the problem.
Yes, I noticed this same problem on my system, rsync arrived via up2date, and suddenly some of by backup scripts stopped working. Happy to report that the above RPM solves my problem too.
