2014-10-30drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packetsBen Hutchings
UFO is now disabled on all drivers that work with virtio net headers, but userland may try to send UFO/IPv6 packets anyway. Instead of sending with ID=0, we should select identifiers on their behalf (as we used to).

2014-10-30net: skb_fclone_busy() needs to detect orphaned skbEric Dumazet
Some drivers are unable to perform TX completions in a bound time.

2014-10-30ipv4: Do not cache routing failures due to disabled forwarding.Nicolas Cavallari
If we cache them, the kernel will reuse them, independently of whether forwarding is enabled or not. Which means that if forwarding is disabled on the input interface where the first routing request comes from, then that unreachable result will be cached and reused for other interfaces, even if forwarding is enabled on them. The opposite is also true. This can be verified with two interfaces A and B and an output interface C, where B has forwarding enabled, but not A and trying ip route get $dst iif A from $src && ip route get $dst iif B from $src Signed-off-by: Nicolas Cavallari <nicolas.cavallari@green-communications.fr> Reviewed-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

2014-10-30ip6_tunnel: allow to change mode for the ip6tnl0Alexey Andriyanov
The fallback device is in ipv6 mode by default. The mode can not be changed in runtime, so there is no way to decapsulate ip4in6 packets coming from various sources without creating the specific tunnel ifaces for each peer. This allows to update the fallback tunnel device, but only the mode could be changed. Usual command should work for the fallback device: `ip -6 tun change ip6tnl0 mode any` The fallback device can not be hidden from the packet receiver as a regular tunnel, but there is no need for synchronization as long as we do single assignment.

2014-10-30net: dsa: Don't set skb->protocol on outgoing tagged packetsGuenter Roeck
Setting skb->protocol to a private protocol type may result in warning messages such as e1000e 0000:00:19.0 em1: checksum_partial proto=dada! This happens if the L3 protocol is IP or IPv6 and skb->ip_summed is set to CHECKSUM_PARTIAL. Looking through the code, it appears that changing skb->protocol for transmitted packets is not necessary and may actually be harmful. For example, it prevents purposely unmodified (from a DSA perspective) network drivers from properly setting up their transmit checksum offload pointers since they inspect skb->protocol to set up the IPv4 header or IPv6 header pointers. So don't unnecessarily change the protocol field. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-30mac80211: properly flush delayed scan work on interface removalJohannes Berg
When an interface is deleted, an ongoing hardware scan is canceled and the driver must abort the scan, at the very least reporting completion while the interface is removed. However, if it scheduled the work that might only run after everything is said and done, which leads to cfg80211 warning that the scan isn't reported as finished yet; this is no fault of the driver, it already did, but mac80211 hasn't processed it. To fix this situation, flush the delayed work when the interface being removed is the one that was executing the scan.

2014-10-30libceph: use memalloc flags for net IOMike Christie
This patch has ceph's lib code use the memalloc flags. If the VM layer needs to write data out to free up memory to handle new allocation requests, the block layer must be able to make forward progress. To handle that requirement we use structs like mempools to reserve memory for objects like bios and requests. The problem is when we send/receive block layer requests over the network layer, net skb allocations can fail and the system can lock up. To solve this, the memalloc related flags were added. NBD, iSCSI and NFS uses these flags to tell the network/vm layer that it should use memory reserves to fullfill allcation requests for structs like skbs. I am running ceph in a bunch of VMs in my laptop, so this patch was not tested very harshly. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Reviewed-by: Ilya Dryomov <idryomov@redhat.com>

2014-10-29inet: frags: remove the WARN_ON from inet_evict_bucketNikolay Aleksandrov
The WARN_ON in inet_evict_bucket can be triggered by a valid case: inet_frag_kill and inet_evict_bucket can be running in parallel on the same queue which means that there has been at least one more ref added by a previous inet_frag_find call, but inet_frag_kill can delete the timer before inet_evict_bucket which will cause the WARN_ON() there to trigger since we'll have refcnt!=1. Now, this case is valid because the queue is being "killed" for some reason (removed from the chain list and its timer deleted) so it will get destroyed in the end by one of the inet_frag_put() calls which reaches 0 i.e. refcnt is still valid.

2014-10-29inet: frags: fix a race between inet_evict_bucket and inet_frag_killNikolay Aleksandrov
When the evictor is running it adds some chosen frags to a local list to be evicted once the chain lock has been released but at the same time the *frag_queue can be running for some of the same queues and it may call inet_frag_kill which will wait on the chain lock and will then delete the queue from the wrong list since it was added in the eviction one. The fix is simple - check if the queue has the evict flag set under the chain lock before deleting it, this is safe because the evict flag is set only under that lock and having the flag set also means that the queue has been detached from the chain list, so no need to delete it again. An important note to make is that we're safe w.r.t refcnt because inet_frag_kill and inet_evict_bucket will sync on the del_timer operation where only one of the two can succeed (or if the timer is executing - none of them), the cases are: 1. inet_frag_kill succeeds in del_timer - then the timer ref is removed, but inet_evict_bucket will not add this queue to its expire list but will restart eviction in that chain 2. inet_evict_bucket succeeds in del_timer - then the timer ref is kept until the evictor "expires" the queue, but inet_frag_kill will remove the initial ref and will set INET_FRAG_COMPLETE which will make the frag_expire fn just to remove its ref. In the end all of the queue users will do an inet_frag_put and the one that reaches 0 will free it. The refcount balance should be okay.

2014-10-29net: ipv6: Add a sysctl to make optimistic addresses useful candidatesErik Kline
Add a sysctl that causes an interface's optimistic addresses to be considered equivalent to other non-deprecated addresses for source address selection purposes. Preferred addresses will still take precedence over optimistic addresses, subject to other ranking in the source address selection algorithm. This is useful where different interfaces are connected to different networks from different ISPs (e.g., a cell network and a home wifi network). The current behaviour complies with RFC 3484/6724, and it makes sense if the host has only one interface, or has multiple interfaces on the same network (same or cooperating administrative domain(s), but not in the multiple distinct networks case. For example, if a mobile device has an IPv6 address on an LTE network and then connects to IPv6-enabled wifi, while the wifi IPv6 address is undergoing DAD, IPv6 connections will try use the wifi default route with the LTE IPv6 address, and will get stuck until they time out. Also, because optimistic nodes can receive frames, issue an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC flag appropriately set). A second RTM_NEWADDR is sent if DAD completes (the address flags have changed), otherwise an RTM_DELADDR is sent. Also: add an entry in ip-sysctl.txt for optimistic_dad.
