* WAN: HDLC: Detach protocol before unregistering deviceAndrew Lunn2015-12-051-1/+1
| | | | | | | | | | | The current code first unregisters the device, and then detaches the protocol from it. This should be performed the other way around, since the detach may try to use state which has been freed by the unregister. Swap the order, so that we first detach and then remove the netdev.

* wan/x25: Fix use-after-free in x25_asy_open_tty()Peter Hurley2015-12-011-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The N_X25 line discipline may access the previous line discipline's closed and already-freed private data on open [1]. The tty->disc_data field _never_ refers to valid data on entry to the line discipline's open() method. Rather, the ldisc is expected to initialize that field for its own use for the lifetime of the instance (ie. from open() to close() only).

* net: better IFF_XMIT_DST_RELEASE supportEric Dumazet2014-10-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Testing xmit_more support with netperf and connected UDP sockets, I found strange dst refcount false sharing. Current handling of IFF_XMIT_DST_RELEASE is not optimal. Dropping dst in validate_xmit_skb() is certainly too late in case packet was queued by cpu X but dequeued by cpu Y The logical point to take care of drop/force is in __dev_queue_xmit() before even taking qdisc lock. As Julian Anastasov pointed out, need for skb_dst() might come from some packet schedulers or classifiers. This patch adds new helper to cleanly express needs of various drivers or qdiscs/classifiers. Drivers that need skb_dst() in their ndo_start_xmit() should call following helper in their setup instead of the prior : dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -> netif_keep_dst(dev); Instead of using a single bit, we use two bits, one being eventually rebuilt in bonding/team drivers. The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being rebuilt in bonding/team. Eventually, we could add something smarter later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new header file include/net/Space.h which contains prototype declaration of sbni_probe(). Include the new header file in drivers/net/Space.c and drivers/net/wan/sbni.c because they use this function. This eliminates the following warning in wan/sbni.c: drivers/net/wan/sbni.c:224:12: warning: no previous prototype for ‘sbni_probe’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: David S.

The net/bridge/br_private.h conflict was a function signature (argument addition) change overlapping with the extern removals from Joe Perches. In drivers/net/netconsole.c we had one change adjusting a printk message whilst another changed "printk(KERN_INFO" into "pr_info(". Lastly, the emulex change was a new inline function addition overlapping with Joe Perches's extern removals. Signed-off-by: David S. Miller <davem@davemloft.net>
