Though we don't export the /proc/sys/net/ipv[4,6]/neigh/default/ directory to the un-init_net, but we can still use cmd such as "ip ntable change name arp_cache locktime 129" to change the locktime of default neigh_parms. This patch disallows the un-init_net to find out the neigh_table.parms. So the un-init_net will failed to influence the init_net.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Johannes Berg 提交于
Since my commit 3713b4e3 ("nl80211: allow splitting wiphy information in dumps"), nl80211_dump_wiphy() uses the global nl80211_fam.attrbuf for parsing the incoming data. This wouldn't be a problem if it only did so on the first dump iteration which is locked against other commands in generic netlink, but due to space constraints in cb->args (the needed state doesn't fit) I decided to always parse the original message. That's racy though since nl80211_fam.attrbuf could be used by some other parsing in generic netlink concurrently. For now, fix this by allocating a separate parse buffer (it's a bit too big for the stack, currently 1448 bytes on 64-bit). For -next, I'll change the code to parse into the global buffer in the first round only and then allocate a smaller buffer to keep the data in cb->args.

The check introduced by: commit 26a41ae6 Author: stephen hemminger <stephen@networkplumber.org> Date: Mon Jun 17 12:09:58 2013 -0700 vxlan: only migrate dynamic FDB entries was not correct because it is checking flag about type of FDB entry, rather than the state (dynamic versus static). The confusion arises because vxlan is reusing values from bridge, and bridge is reusing values from neighbour table, and easy to get lost in translation.

The usb_8dev hardware has problems on some xhci USB hosts. The driver fails to read the firmware revision in the probe function. This leads to the following Oops: [ 3356.635912] kernel BUG at net/core/dev.c:5701! The driver tries to free the netdev, which has already been registered, without unregistering it. This patch fixes the problem by unregistering the netdev in the error path.
