netlink_dump() allocates skb based on the calculated min_dump_alloc or a per socket max_recvmsg_len. min_alloc_size is maximum space required for any single netdev attributes as calculated by rtnl_calcit(). max_recvmsg_len tracks the user provided buffer to netlink_recvmsg. It is capped at 16KiB. The intention is to avoid small allocations and to minimize the number of calls required to obtain dump information for all net devices. netlink_dump packs as many small messages as could fit within an skb that was sized for the largest single netdev information. The actual space available within an skb is larger than what is requested. It could be much larger and up to near 2x with align to next power of 2 approach. Allowing netlink_dump to use all the space available within the allocated skb increases the buffer size a user has to provide to avoid truncaion (i.e. MSG_TRUNG flag set). It was observed that with many VLANs configured on at least one netdev, a larger buffer of near 64KiB was necessary to avoid "Message truncated" error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when min_alloc_size was only little over 32KiB. This patch trims skb to allocated size in order to allow the user to avoid truncation with more reasonable buffer size. Signed-off-by:

Greg reported crashes hitting the following check in __sk_backlog_rcv() BUG_ON(!sock_flag(sk, SOCK_MEMALLOC)); The pfmemalloc bit is currently checked in sk_filter(). This works correctly for TCP, because sk_filter() is ran in tcp_v[46]_rcv() before hitting the prequeue or backlog checks. For UDP or other protocols, this does not work, because the sk_filter() is ran from sock_queue_rcv_skb(), which might be called _after_ backlog queuing if socket is owned by user by the time packet is processed by softirq handler.

ip6_blackhole_route() does not initialize the newly allocated rt6_info properly. This patch: 1. Call rt6_info_init() to initialize rt6i_siblings and rt6i_uncached 2. The current rt->dst._metrics init code is incorrect: - 'rt->dst._metrics = ort->dst._metris' is not always safe - Not sure what dst_copy_metrics() is trying to do here considering ip6_rt_blackhole_cow_metrics() always returns NULL Fix: - Always do dst_copy_metrics() - Replace ip6_rt_blackhole_cow_metrics() with dst_cow_metrics_generic() 3. Mask out the RTF_PCPU bit from the newly allocated blackhole route. This bug triggers an oops (reported by Phil Sutter) in rt6_get_cookie(). It is because RTF_PCPU is set while rt->dst.from is NULL.

In commit e3eea1eb ("tipc: clean up handling of message priorities") we introduced a field in the packet header for keeping track of the priority of fragments, since this value is not present in the specified protocol header. Since the value so far only is used at the transmitting end of the link, we have not yet officially defined it as part of the protocol. Unfortunately, the field we use for keeping this value, bits 13-15 in in word 5, has turned out to be a poor choice; it is already used by the broadcast protocol for carrying the 'network id' field of the sending node. Since packet fragments also need to be transported across the broadcast protocol, the risk of conflict is obvious, and we see this happen when we use network identities larger than 2^13-1. This has escaped our testing because we have so far only been using small network id values. We now move this field to bits 0-2 in word 9, a field that is guaranteed to be unused by all involved protocols. Fixes: e3eea1eb ("tipc: clean up handling of message priorities") Signed-off-by:

In commit 6e498158 ("tipc: move link synch and failover to link aggregation level") we introduced a new mechanism for performing link failover and synchronization. We have now detected a bug in this mechanism. During link synchronization we use the arrival of any packet on the tunnel link to trig a check for whether it has reached the synchronization point or not. This has turned out to be too permissive, since it may cause an arriving non-last SYNCH packet to end the synch state, just to see the next SYNCH packet initiate a new synch state with a new, higher synch point. This is not fatal, but should be avoided, because it may significantly extend the synchronization period, while at the same time we are not allowed to send NACKs if packets are lost. In the worst case, a low-traffic user may see its traffic stall until a LINK_PROTOCOL state message trigs the link to leave synchronization state. At the same time, LINK_PROTOCOL packets which happen to have a (non- valid) sequence number lower than the tunnel link's rcv_nxt value will be consistently dropped, and will never be able to resolve the situation described above. We fix this by exempting LINK_PROTOCOL packets from the sequence number check, as they should be. We also reduce (but don't completely eliminate) the risk of entering multiple synchronization states by only allowing the (logically) first SYNCH packet to initiate a synchronization state. This works independently of actual packet arrival order. Fixes: commit 6e498158 ("tipc: move link synch and failover to link aggregation level") Signed-off-by:

As originally written rt6_uncached_list_flush_dev makes no sense when called with dev == NULL as it attempts to flush all uncached routes regardless of network namespace when dev == NULL. Which is simply incorrect behavior. Furthermore at the point rt6_ifdown is called with dev == NULL no more network devices exist in the network namespace so even if the code in rt6_uncached_list_flush_dev were to attempt something sensible it would be meaningless. Therefore remove support in rt6_uncached_list_flush_dev for handling network devices where dev == NULL, and only call rt6_uncached_list_flush_dev when rt6_ifdown is called with a network device.

Sathya Perla says: ==================== be2net: patch set Patch 1 fixes a FW image compatibility check in the driver that prevents certain FW images from being flashed on BE3 (not BE3-R) adapters. Patch 2 fixes a spin_lock not being released in a failure case in be_cmd_notify_wait(). Patch 3 includes a workaround to pad packets that are only 32b long or less to be applicabe to BE3 too. This workaround was currently applied only to Skyhawk and Lancer chips. Such packets are causing BE3's TX path to stall on a SR-IOV config. Patch 4 fixes the be_cmd_get_profile_config() routine to set the pf_num field in the cmd request. The FW requires this field to be set for it to return the specific function's descriptors. If not set, the FW returns the descriptors of all the functions on the device. If the first descriptor is not what is being queried for, the driver will read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG cmd. Patch 5 completes an earlier fix that removed the vlan promisc capability for VFs. The earlier fix did not update the removal of this capability from the profile descriptor of the VF. This causes the VF driver to request this capability when it tries to create it's interface at probe time. This could potentailly cause the VF probe to fail if the FW enforces strict checking of the flags based on what was provisoned by the PF. This strict checking is not being done by FW currently but will be fixed in a future version. This patch fixes this issue by updating the VF's profile descriptor so that they match the interface capability flags provisioned by the PF. Pls consider adding these patches to the net tree.

commit afae5ad7 "net/fsl_pq_mdio: streamline probing of MDIO nodes" added support for different types of MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) However, the implementation for types 1 and 4 would mistakenly assume a mapping of the full MDIO register set, thereby computing the address for the TBI register starting from the containing structure. The TBI register would therefore be accessed at a wrong (much bigger) address, not giving the expected result at all. This patch restores the correct behavior we had prior to the above one. The consequences of this bug are apparent when trying to access a PHY with the same address as the value contained in the initial value of the TBI register (normally 0); in that case you'll get answers from the internal TBI device (even though MDIO/MDC pins are actually *also* toggling on the physical bus!). Beware that you also need to add a fake tbi node to your device tree with an unused address. Notice how this fix is related to commit 22066949 "powerpc: Add TBI PHY node to first MDIO bus" which fixed the behavior in kernel 3.3, which was later broken by the above commit on kernel 3.7.
