2016-12-20net: phy: fix sign type error in genphy_config_eee_advertjbrunet
In genphy_config_eee_advert, the return value of phy_read_mmd_indirect is checked to know if the register could be accessed but the result is assigned to a 'u32'. Changing to 'int' to correctly get errors from phy_read_mmd_indirect.

The build of sparc allmodconfig fails with the error: "of_irq_to_resource" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined! of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can safely use #if defined(CONFIG_OF_IRQ) in the code.

2016-12-17virtio_net: xdp, add slowpath case for non contiguous buffersJohn Fastabend
virtio_net XDP support expects receive buffers to be contiguous. If this is not the case we enable a slowpath to allow connectivity to continue but at a significan performance overhead associated with linearizing data. To make it painfully aware to users that XDP is running in a degraded mode we throw an xdp buffer error. To linearize packets we allocate a page and copy the segments of the data, including the header, into it. After this the page can be handled by XDP code flow as normal. Then depending on the return code the page is either freed or sent to the XDP xmit path. There is no attempt to optimize this path. This case is being handled simple as a precaution in case some unknown backend were to generate packets in this form. To test this I had to hack qemu and force it to generate these packets. I do not expect this case to be generated by "real" backends. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-17virtio_net: add XDP_TX supportJohn Fastabend
This adds support for the XDP_TX action to virtio_net. When an XDP program is run and returns the XDP_TX action the virtio_net XDP implementation will transmit the packet on a TX queue that aligns with the current CPU that the XDP packet was processed on. Before sending the packet the header is zeroed. Also XDP is expected to handle checksum correctly so no checksum offload support is provided.

2016-12-17virtio_net: add dedicated XDP transmit queuesJohn Fastabend
XDP requires using isolated transmit queues to avoid interference with normal networking stack (BQL, NETDEV_TX_BUSY, etc). This patch adds a XDP queue per cpu when a XDP program is loaded and does not expose the queues to the OS via the normal API call to netif_set_real_num_tx_queues(). This way the stack will never push an skb to these queues. However virtio/vhost/qemu implementation only allows for creating TX/RX queue pairs at this time so creating only TX queues was not possible. And because the associated RX queues are being created I went ahead and exposed these to the stack and let the backend use them. This creates more RX queues visible to the network stack than TX queues which is worth mentioning but does not cause any issues as far as I can tell.

2016-12-17virtio_net: Add XDP supportJohn Fastabend
This adds XDP support to virtio_net. Some requirements must be met for XDP to be enabled depending on the mode. First it will only be supported with LRO disabled so that data is not pushed across multiple buffers. Second the MTU must be less than a page size to avoid having to handle XDP across multiple pages. If mergeable receive is enabled this patch only supports the case where header and data are in the same buf which we can check when a packet is received by looking at num_buf. If the num_buf is greater than 1 and a XDP program is loaded the packet is dropped and a warning is thrown. When any_header_sg is set this does not happen and both header and data is put in a single buffer as expected so we check this when XDP programs are loaded. Subsequent patches will process the packet in a degraded mode to ensure connectivity and correctness is not lost even if backend pushes packets into multiple buffers. If big packets mode is enabled and MTU/LRO conditions above are met then XDP is allowed. This patch was tested with qemu with vhost=on and vhost=off where mergeable and big_packet modes were forced via hard coding feature negotiation. Multiple buffers per packet was forced via a small test patch to vhost.c in the vhost=on qemu mode.

Locally originated traffic in a VRF fails in the presence of a POSTROUTING rule.

PING 11.1.1.3 (11.1.1.3) from 11.1.1.2 red: 56(84) bytes of data. ping: sendmsg: Operation not permitted Worse, the above causes random corruption resulting in a panic in random places (I have not seen a consistent backtrace). Call nf_reset to drop the conntrack info following the pass through the VRF device. The nf_reset is needed on Tx but not Rx because of the order in which NF_HOOK's are hit: on Rx the VRF device is after the real ingress device and on Tx it is is before the real egress device. Connection tracking should be tied to the real egress device and not the VRF device.

2016-12-16encx24j600: bugfix - always move ERXTAIL to next packet in encx24j600_rx_packetsJeroen De Wachter
Before, encx24j600_rx_packets did not update encx24j600_priv's next_packet member when an error occurred during packet handling (either because the packet's RSV header indicates an error or because the encx24j600_receive_packet method can't allocate an sk_buff). If the next_packet member is not updated, the ERXTAIL register will be set to the same value it had before, which means the bad packet remains in the component's memory and its RSV header will be read again when a new packet arrives. If the RSV header indicates a bad packet or if sk_buff allocation continues to fail, new packets will be stored in the component's memory until that memory is full, after which packets will be dropped. The SETPKTDEC command is always executed though, so the encx24j600 hardware has an incorrect count of the packets in its memory. To prevent this, the next_packet member should always be updated, allowing the packet to be skipped (either because it's bad, as indicated in its RSV header, or because allocating an sk_buff failed). In the allocation failure case, this does mean dropping a valid packet, but dropping the oldest packet to keep as much memory as possible available for new packets seems preferable to keeping old (but valid) packets around while dropping new ones.

2016-12-16net/3com/3c515: Fix timer handling, prevent leaks and crashesThomas Gleixner
The timer handling in this driver is broken in several ways: - corkscrew_open() initializes and arms a timer before requesting the device interrupt. If the request fails the timer stays armed. A second call to corkscrew_open will unconditionally reinitialize the quued timer and arm it again. Also a immediate device removal will leave the timer queued because close() is not called (open() failed) and therefore nothing issues del_timer(). The reinitialization corrupts the link chain in the timer wheel hash bucket and causes a NULL pointer dereference when the timer wheel tries to operate on that hash bucket. Immediate device removal lets the link chain poke into freed and possibly reused memory. Solution: Arm the timer after the successful irq request. - corkscrew_close() uses del_timer() On close the timer is disarmed with del_timer() which lets the following code race against a concurrent timer expiry function. Solution: Use del_timer_sync() instead - corkscrew_close() calls del_timer() unconditionally del_timer() is invoked even if the timer was never initialized. This works by chance because the struct containing the timer is zeroed at allocation time. Solution: Move the setup of the timer into corkscrew_setup().

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs updates from Al Viro: - more ->d_init() stuff (work.dcache) - pathname resolution cleanups (work.namei) - a few missing iov_iter primitives - copy_from_iter_full() and friends. Either copy the full requested amount, advance the iterator and return true, or fail, return false and do _not_ advance the iterator. Quite a few open-coded callers converted (and became more readable and harder to fuck up that way) (work.iov_iter) - several assorted patches, the big one being logfs removal * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: logfs: remove from tree vfs: fix put_compat_statfs64() does not handle errors namei: fold should_follow_link() with the step into not-followed link namei: pass both WALK_GET and WALK_MORE to should_follow_link() namei: invert WALK_PUT logics namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link() namei: saner calling conventions for mountpoint_last() namei.c: get rid of user_path_parent() switch getfrag callbacks to ..._full() primitives make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success [iov_iter] new primitives - copy_from_iter_full() and friends don't open-code file_inode() ceph: switch to use of ->d_init() ceph: unify dentry_operations instances lustre: switch to use of ->d_init()

2016-12-16Merge tag 'powerpc-4.10-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for the kexec_file_load() syscall, which is a prereq for secure and trusted boot. - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN). - Sort the exception tables at build time, to save time at boot, and store them as relative offsets to save space in the kernel image & memory. - Allow building the kernel with thin archives, which should allow us to build an allyesconfig once some other fixes land. - Build fixes to allow us to correctly rebuild when changing the kernel endian from big to little or vice versa. - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix. - Initial stack protector support (-fstack-protector). - Support for dumping the radix (aka. Linux) and hash page tables via debugfs. - Fix an oops in cxl coredump generation when cxl_get_fd() is used. - Freescale updates from Scott: "Highlights include 8xx hugepage support, qbman fixes/cleanup, device tree updates, and some misc cleanup." - Many and varied fixes and minor enhancements as always.
