Pull networking fixes from David S Miller: 1) Netfilter xt_limit module can use uninitialized rules, from Jan Engelhardt. 2) Wei Yongjun has found several more spots where error pointers were treated as NULL/non-NULL and vice versa. 3) bnx2x was converted to pci_io{,un}map() but one remaining plain iounmap() got missed. From Neil Horman. 4) Due to a fence-post type error in initialization of inetpeer entries (which is where we store the ICMP rate limiting information), we can erroneously drop ICMPs if the inetpeer was created right around when jiffies wraps. Fix from Nicolas Dichtel. 5) smsc75xx resume fix from Steve Glendinnig. 6) LAN87xx smsc chips need an explicit hardware init, from Marek Vasut. 7) qlcnic uses msleep() with locks held, fix from Narendra K. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netdev: octeon: fix return value check in octeon_mgmt_init_phy() inetpeer: fix token initialization qlcnic: Fix scheduling while atomic bug bnx2: Clean up remaining iounmap net: phy: smsc: Implement PHY config_init for LAN87xx smsc75xx: fix resume after device reset netdev: pasemi: fix return value check in pasemi_mac_phy_init() team: fix return value check l2tp: fix return value check netfilter: xt_limit: have r->cost != 0 case work

The host controller bugfix was reported in older kernels as being pretty easy to trigger, and has been tested by Red Hat and their customers.

We currently use percpu order-0 pages in __netdev_alloc_frag to deliver fragments used by __netdev_alloc_skb() Depending on NIC driver and arch being 32 or 64 bit, it allows a page to be split in several fragments (between 1 and 8), assuming PAGE_SIZE=4096 Switching to bigger pages (32768 bytes for PAGE_SIZE=4096 case) allows : - Better filling of space (the ending hole overhead is less an issue) - Less calls to page allocator or accesses to page->_count - Could allow struct skb_shared_info futures changes without major performance impact. This patch implements a transparent fallback to smaller pages in case of memory pressure. It also uses a standard "struct page_frag" instead of a custom one. Signed-off-by:

When jiffies wraps around (for example, 5 minutes after the boot, see INITIAL_JIFFIES) and peer has just been created, now - peer->rate_last can be < XRLIM_BURST_FACTOR * timeout, so token is not set to the maximum value, thus some icmp packets can be unexpectedly dropped. Fix this case by initializing last_rate to 60 seconds in the past. Signed-off-by:

In the device close path, 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' call msleep. But 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock held resulting in scheduling while atomic bug causing the following trace. I observed that the commit 012dc19a from John Fastabend addresses a similar issue in ixgbevf driver. Adopting the same approach used in the commit, this patch uses mdelay to address the issue.

Linux tunnels were written before RFC6040 and therefore never implemented the corner case of ECN getting set in the outer header and the inner header not being ready for it. Section 4.2. Default Tunnel Egress Behaviour. o If the inner ECN field is Not-ECT, the decapsulator MUST NOT propagate any other ECN codepoint onwards. This is because the inner Not-ECT marking is set by transports that rely on dropped packets as an indication of congestion and would not understand or respond to any other ECN codepoint [RFC4774]. Specifically: * If the inner ECN field is Not-ECT and the outer ECN field is CE, the decapsulator MUST drop the packet. * If the inner ECN field is Not-ECT and the outer ECN field is Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the outgoing packet with the ECN field cleared to Not-ECT. This patch moves the ECN decap logic out of the individual tunnels into a common place. It also adds logging to allow detecting broken systems that set ECN bits incorrectly when tunneling (or an intermediate router might be changing the header). Overloads rx_frame_error to keep track of ECN related error. Thanks to Chris Wright who caught this while reviewing the new VXLAN tunnel. This code was tested by injecting faulty logic in other end GRE to send incorrectly encapsulated packets. Signed-off-by:

GRE driver incorrectly uses zero as a flag value. Zero is a perfectly valid value for key, and the tunnel should match packets with no key only with tunnels created without key, and vice versa. This is a slightly visible change since previously it might be possible to construct a working tunnel that sent key 0 and received only because of the key wildcard of zero. I.e the sender sent key of zero, but tunnel was defined without key. Note: using gre key 0 requires iproute2 utilities v3.2 or later. The original utility code was broken as well. Signed-off-by:

This patch adds a new common code routine to upgrade an adapter's firmware. This routine handles all of the complexities of working with the the existing adapter firmware in order to quiesce the adapter and uP, etc. For an automatic upgrade it will send a HELLO command to check if cxgb4 want/can upgrade firmware, i.e. if cxgb4 is MASTER and has newer firmware that it wants to load and call the new common code routine t4_fw_upgrade. Note that it should not issue a RESET command after a successful firmware upgrade. Signed-off-by:

If a card had already been initialized, on reloading cxgb4 driver firmware required an upgrade but the upgrade did not happen. In that case a mailbox timeout would occur during T4 configuration file stuff. The fix is to let the caller know the firmware was not upgraded so a reset would be issued before starting the T4 config stuff. Signed-off-by:
