Net device reset can fail when the h/w or f/w is in a bad state. Subsequent netdevice open fails in bnxt_hwrm_stat_ctx_alloc(). The cleanup invokes bnxt_hwrm_resource_free() which inturn calls bnxt_disable_int(). In this routine, the code segment if (ring->fw_ring_id != INVALID_HW_RING_ID) BNXT_CP_DB(cpr->cp_doorbell, cpr->cp_raw_cons); results in NULL pointer dereference as cpr->cp_doorbell is not yet initialized, and fw_ring_id is zero. The fix is to initialize cpr fw_ring_id to INVALID_HW_RING_ID before bnxt_init_chip() is invoked. Signed-off-by:

The Rx path may grab the socket right before pppol2tp_release(), but nothing guarantees that it will enqueue packets before skb_queue_purge(). Therefore, the socket can be destroyed without its queues fully purged. Fix this by purging queues in pppol2tp_session_destruct() where we're guaranteed nothing is still referencing the socket.

The code following l2tp_tunnel_find() expects that a new reference is held on sk. Either sk_receive_skb() or the discard_put error path will drop a reference from the tunnel's socket. This issue exists in both l2tp_ip and l2tp_ip6. Fixes: a3c18422 ("l2tp: hold socket before dropping lock in l2tp_ip{, 6}_recv()") Signed-off-by:

The reference count held for skb needs to be released when the skb's nfct pointer is cleared regardless of if nf_ct_delete() is called or not. Failing to release the skb's reference cound led to deferred conntrack cleanup spinning forever within nf_conntrack_cleanup_net_list() when cleaning up a network namespace: kworker/u16:0-19025 [004] 45981067.173642: sched_switch: kworker/u16:0:19025 [120] R ==> rcu_preempt:7 [120] kworker/u16:0-19025 [004] 45981067.173651: kernel_stack: <stack trace> => ___preempt_schedule (ffffffffa001ed36) => _raw_spin_unlock_bh (ffffffffa0713290) => nf_ct_iterate_cleanup (ffffffffc00a4454) => nf_conntrack_cleanup_net_list (ffffffffc00a5e1e) => nf_conntrack_pernet_exit (ffffffffc00a63dd) => ops_exit_list.isra.1 (ffffffffa06075f3) => cleanup_net (ffffffffa0607df0) => process_one_work (ffffffffa0084c31) => worker_thread (ffffffffa008592b) => kthread (ffffffffa008bee2) => ret_from_fork (ffffffffa071b67c) Fixes: dd41d33f ("openvswitch: Add force commit.")

gcc-7 reports a warning that earlier versions did not have: drivers/net/ethernet/rocker/rocker_ofdpa.c: In function 'ofdpa_port_stp_update': arch/x86/include/asm/string_32.h:79:22: error: '*((void *)&prev_ctrls+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized] *((short *)to + 2) = *((short *)from + 2); ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/rocker/rocker_ofdpa.c:2218:7: note: '*((void *)&prev_ctrls+4)' was declared here This is clearly a variation of the warning about 'prev_state' that was shut up using uninitialized_var(). We can slightly simplify the code and get rid of the warning by unconditionally saving the prev_state and prev_ctrls variables. The inlined memcpy is not particularly expensive here, as it just has to read five bytes from one or two cache lines. Signed-off-by:

moxart_mac_start_xmit() doesn't care where tx_tail is, tx_head can catch and pass tx_tail, which is bad because moxart_tx_finished() isn't guaranteed to catch up on freeing resources from tx_tail. Add a check in moxart_mac_start_xmit() stopping the queue at the end of the circular buffer. Also add a check in moxart_tx_finished() waking the queue if the buffer has TX_WAKE_THRESHOLD or more free descriptors. While we're at it, move spin_lock_irq() to happen before our descriptor pointer is assigned in moxart_mac_start_xmit(). Addresses https://bugzilla.kernel.org/show_bug.cgi?id=99451Signed-off-by:

David Laight noticed the support for MSG_MORE with datamsg->force_delay didn't really work as we expected, as the first msg with MSG_MORE set would always block the following chunks' dequeuing. This Patch is to rewrite it by saving the MSG_MORE flag into assoc as David Laight suggested. asoc->force_delay is used to save MSG_MORE flag before a msg is sent. All chunks in queue would not be sent out if asoc->force_delay is set by the msg with MSG_MORE flag, until a new msg without MSG_MORE flag clears asoc->force_delay. Note that this change would not affect the flush is generated by other triggers, like asoc->state != ESTABLISHED, queue size > pmtu etc. v1->v2: Not clear asoc->force_delay after sending the msg with MSG_MORE flag.

Our chosen ic_dev may be anywhere in our list of ic_devs, and we may free it before attempting to close others. When we compare d->dev and ic_dev->dev, we're potentially dereferencing memory returned to the allocator. This causes KASAN to scream for each subsequent ic_dev we check. As there's a 1-1 mapping between ic_devs and netdevs, we can instead compare d and ic_dev directly, which implicitly handles the !ic_dev case, and avoids the use-after-free. The ic_dev pointer may be stale, but we will not dereference it.

Like: if (ptr + 16 > data_end) return TC_ACT_SHOT; // may be followed by if (ptr + 14 > data_end) return TC_ACT_SHOT; while llvm can see that 'ptr' is valid for all 16 bytes, the verifier could not.

This change basically codifies what I think was already the limitations on the busy_poll and busy_read sysctl interfaces. We weren't checking the lower bounds and as such could input negative values. The behavior when that was used was dependent on the architecture. In order to prevent any issues with that I am just disabling support for values less than 0 since this way we don't have to worry about any odd behaviors. By limiting the sysctl values this way it also makes it consistent with how we handle the SO_BUSY_POLL socket option since the value appears to be reported as a signed integer value and negative values are rejected.

The fact that we only get a warning for one of the two functions seems to be arbitrary, based on the inlining decisions in the compiler. To address this, I'm making both functions do the same thing: - set the clscode from the ioc structure in both - set the time stamp from ktime_get_real_seconds (which also avoids the signed-integer overflow in 2038 and extends the well-defined behavior until 2106). - zero-fill the reserved field Fixes: 8b230ed8 ("bna: Brocade 10Gb Ethernet device driver") Signed-off-by:

With AF_IUCV traffic, the skb passed to hard_start_xmit() has a 14 byte slot at skb->data, intended for an ETH header. qeth_l3_fill_af_iucv_hdr() fills this ETH header... and then immediately moves it to the skb's headroom, where it disappears and is never seen again. But it's still possible for us to return NETDEV_TX_BUSY after the skb has been modified. Since we didn't get a private copy of the skb, the next time the skb is delivered to hard_start_xmit() it no longer has the expected layout (we moved the ETH header to the headroom, so skb->data now starts at the IUCV_TRANS header). So when qeth_l3_fill_af_iucv_hdr() does another round of rebuilding, the resulting qeth header ends up all wrong. On transmission, the buffer is then rejected by the HiperSockets device with SBALF15 = x'04'. When this error is passed back to af_iucv as TX_NOTIFY_UNREACHABLE, it tears down the offending socket. As the ETH header for AF_IUCV serves no purpose, just align the code to what we do for IP traffic on L3 HiperSockets: keep the ETH header at skb->data, and pass down data_offset = ETH_HLEN to qeth_fill_buffer(). When mapping the payload into the SBAL elements, the ETH header is then stripped off. This avoids the skb manipulations in qeth_l3_fill_af_iucv_hdr(), and any buffer re-entering hard_start_xmit() after NETDEV_TX_BUSY is now processed properly. Signed-off-by:

Depending on the device type, hard_start_xmit() builds different output buffer formats. For instance with HiperSockets, on both L2 and L3 we strip the ETH header from the skb - L3 doesn't need it, and L2 carries it in the buffer's header element. For this, we pass data_offset = ETH_HLEN all the way down to __qeth_fill_buffer(), where skb->data is then adjusted accordingly. But the initial size calculation still considers the *full* skb length (including the ETH header). So qeth_get_elements_no() can erroneously reject a skb as too big, even though it would actually fit into an output buffer once the ETH header has been trimmed off later. Fix this by passing an additional offset to qeth_get_elements_no(), that indicates where in the skb the on-wire data actually begins. Since the current code uses data_offset=-1 for some special handling on OSA, we need to clamp data_offset to 0... On HiperSockets this helps when sending ~MTU-size skbs with weird page alignment. No change for OSA or AF_IUCV. Signed-off-by:

The linking status may be changed when autosuspend. And, after autoresume, the driver may try to transmit packets when the device is carrier off, because the interrupt transfer doesn't update the linking status, yet. And, if the device is in ALDPS mode, the device would stop working. The another similar case is 1. unplug the cable. 2. interrupt transfer queue a work_queue for linking change. 3. device enters the ALDPS mode. 4. a tx occurs before the work_queue is called.

If the PHY is halted on stop, then do not set the state to PHY_UP. This ensures the phy will be restarted later in phy_start when the machine is started again. Fixes: 00db8189 ("This patch adds a PHY Abstraction Layer to the Linux Kernel, enabling ethernet drivers to remain as ignorant as is reasonable of the connected PHY's design and operation details.")

Dmitry posted a nice reproducer of a bug triggering in neigh_probe() when dereferencing a NULL neigh->ops->solicit method. This can happen for arp_direct_ops/ndisc_direct_ops and similar, which can be used for NUD_NOARP neighbours (created when dev->header_ops is NULL). Admin can then force changing nud_state to some other state that would fire neigh timer. Signed-off-by:

Pull btrfs fixes from Chris Mason: "Zygo tracked down a very old bug with inline compressed extents. I didn't tag this one for stable because I want to do individual tested backports. It's a little tricky and I'd rather do some extra testing on it along the way" * 'for-linus-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: btrfs: add missing memset while reading compressed inline extents Btrfs: fix regression in lock_delalloc_pages btrfs: remove btrfs_err_str function from uapi/linux/btrfs.h
