Description James Laska 2008-07-23 20:25:25 UTC

While attempting an NFS install using anaconda-11.4.1.15-1 against
http://porkchop.redhat.com/rawhide/nightly/rawhide-20080721/ppc/os I get the
following error from loader:

loader received SIGABRT!  Backtrace:

you may safely reboot your system


I should note that loader seemed confused with the mount path and at one point
appended "images/stage.img" to the directory.  After manually removing that
text, it accepted the value and proceeded to the segfault above.

[Jul 23 16:25:01] <clumens> | if you want to be really helpful, you can mention
that nfsinstall.c:166 is the troublesome line
[Jul 23 16:25:10] <clumens> | which looks like this:  free(((struct
nfsInstallData *) loaderData->stage2Data)->directory);
[Jul 23 16:25:23] <clumens> | that way i don't have to eu-addr2line again :)

Comment 2 Chris Lumens 2008-07-23 21:19:47 UTC

I don't think it's possible to hit this segfault anymore, so please try
anaconda-11.4.1.18-1 and let me know.  I tried a couple different cmdline
parameters here and wasn't able to trigger the segfault though I was still going
through the same code path.

Comment 3 James Laska 2008-07-24 19:47:00 UTC

Tested (this time with kickstart) using anaconda-11.4.1.18-1 against
http://porkchop.redhat.com/rawhide/nightly/rawhide-20080724/ppc/os 

loader received SIGABRT!  Backtrace:
/sbin/loader(loaderSegvHandler+0xa0)[0x100081e0]
[0x100364]

/lib/libc.so.6(abort+0x260)[0xf8d1590]

install exited abnormally [1/1] 

We can close this one out and do a NEW (or DUP) bz if this is a different issue.

Comment 4 Chris Lumens 2008-07-24 20:38:34 UTC

Ah, this is because I actually need to check the return value of asprintf.  This
will be fixed in the next build of anaconda.
