[Crash-utility] Unknown osrelease information in vmcore with xen

[Dietmar Hahn]

Hi,

I have a SuSE SLES11 vmcore with xen and tried to read the osrelease from the
vmcore with
# crash --osrelease vmcore
unknown

The problem is that there are two notes in the vmcore starting with
"VMCOREINFO":

Elf64_Nhdr:
               n_namesz: 11 ("VMCOREINFO")
               n_descsz: 1384
                 n_type: 0 (unused)
                         OSRELEASE=3.0.101-63-xen
               ...
Elf64_Nhdr:
               n_namesz: 15 ("VMCOREINFO_XEN")
               n_descsz: 4068
                 n_type: 0 (unused)
               ...

In the function dump_Elf64_Nhdr() I found:
    vmcoreinfo = STRNEQ(buf, "VMCOREINFO");

But because the "VMCOREINFO_XEN" ist the second one in the file it wins!

When using
    vmcoreinfo = STREQ(buf, "VMCOREINFO");
all is fine and I get:
# crash --osrelease vmcore
3.0.101-63-xen

So my question is: why is STRNEQ() used?
Thanks!

Dietmar.
