Subject: net: fix iterating over hashtable in tcp_nuke_addr()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4747299b2c8e8778927b3df0501023d76fe4f2d5;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: fix iterating over hashtable in tcp_nuke_addr()

The actual size of the tcp hashinfo table is tcp_hashinfo.ehash_mask + 1
so we need to adjust the loop accordingly to get the sockets hashed into
the last bucket.
