Description David Howells 2005-07-28 17:12:37 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.4; Linux) KHTML/3.4.0 (like Gecko)

Description of problem:
ipv6_add_addr() calls addrconf_dst_alloc(). If that fails, then rt is set to  
an error not a pointer, and the epilogue at "out:" then tries to free what rt  
points to since it isn't NULL.  

Version-Release number of selected component (if applicable):
kernel-2.6.9-11.38.EL

How reproducible:
Didn't try

Steps to Reproduce:
It just happened once. I don't know why, but I know exactly what the problem 
is: see description and patch. 

Actual Results:  It oopsed. 

Expected Results:  No oops.
