I have a brand new centos 6.2 server. The first thing I did is yum -y install aide and then next I did aide --init. Below is a whole lot of errors I got.What does it means must I reinstall it? Or leave it ?

did you yum update the server before installing aide? –  Dmitri Chubarov May 27 '12 at 6:00
    
yes I did that. So then I run this now /usr/sbin/prelink --all and it does not appear any more? Am I on the right track please help me confirm. What is this prelink error actually? –  newbie14 May 27 '12 at 6:16
    
When I ran the /usr/sbin/prelink this is what I got /usr/sbin/prelink: /usr/lib64/xulrunner-2/libxul.so: DT_JMPREL tag not adjacent to DT_RELA relocations /usr/sbin/prelink: /usr/lib64/xulrunner-2/libmozsqlite3.so: DT_JMPREL tag not adjacent to DT_RELA relocations –  newbie14 May 27 '12 at 6:19
    
looks like some of the libraries got updated without recomputing prelink. The JMPREL/RELA conflict is in a number of bug reports. readelf -d is suggested to check the elf structure, and if really important, relink from source rpm, otherwise ignore. –  Dmitri Chubarov May 27 '12 at 6:40
    
I did this readelf -d so what option must I choose now. So what is the best solution you suggest? IS it some critical which might corrupt my system in near future? –  newbie14 May 27 '12 at 8:50

I had the same exact problem after installing a binary that did not use the normal packaging system dependency resolution to properly share libraries. Here are the steps I used to resolve the problem.

  1. First look at the library dependencies for one of the binaries that caused the aide error message. In my case trashapplet:

    for LIB in $(ldd /usr/libexec/trashapplet | awk '{print $3}' | grep '^/' | sort -u); do echo $(dirname $LIB); done | sort -u
    
  2. Next, make sure each directory used by the binary is configured for processing with prelink in /etc/prelink.conf. Add any missing directory to the /etc/prelink.conf. In my case, this was:

    -l /usr/local/oracle/product/*/lib
    
  3. Repeat as necessary.

In my case the binary hijacked the distro's /lib64/libexpat.so.1 library. Because the new library was located outside the normally-prelinked set but overlapped with the existing library, it caused the mis-match at load time no matter how frequently I prelinked.

Why is this error cause in the first place is it indicating something serious? –  newbie14 Oct 5 '12 at 3:18
    
@newbie14: For some values of "serious": "Did a hacker break in": No. "Could it cause bugs and/or security vulnerabilities?": Probably. Binaries are being loaded against a version of the library they were probably not compiled against. –  mormegil Oct 8 '12 at 18:43
    
No this is a fresh machine which I did installation and had this issues so what could be the problem ? –  newbie14 Oct 10 '12 at 1:52
