From: Boris Ostrovsky Date: Mon, 4 Apr 2011 20:07:26 +0000 (-0700) Subject: ipv6: Don't pass invalid dst_entry pointer to dst_release(). X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=738faca34335cd1d5d87fa7c58703139c7fa15bd;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ipv6: Don't pass invalid dst_entry pointer to dst_release(). Make sure dst_release() is not called with error pointer. This is similar to commit 4910ac6c526d2868adcb5893e0c428473de862b5 ("ipv4: Don't ip_rt_put() an error pointer in RAW sockets.").
