Some callbacks used by the upper layers can run while we are in the .remove(). A potential use-after-free can happen, because we free the_virtio_vsock without knowing if the callbacks are over or not. To solve this issue we move the assignment of the_virtio_vsock at the end of .probe(), when we finished all the initialization, and at the beginning of .remove(), before to release resources. For the same reason, we do the same also for the vdev->priv. We use RCU to be sure that all callbacks that use the_virtio_vsock ended before freeing it. This is not required for callbacks that use vdev->priv, because after the vdev->config->del_vqs() we are sure that they are ended and will no longer be invoked. We also take the mutex during the .remove() to avoid that .probe() can run while we are resetting the device. Signed-off-by: NStefano Garzarella <sgarzare@redhat.com> Signed-off-by: NDavid S.

This removes contention over page allocation for XDP_REDIRECT actions by adding page_pool support per queue for the driver.

Add XDP support based on rx page_pool allocator, one frame per page. Page pool allocator is used with assumption that only one rx_handler is running simultaneously. DMA map/unmap is reused from page pool despite there is no need to map whole page. Due to specific of cpsw, the same TX/RX handler can be used by 2 network devices, so special fields in buffer are added to identify an interface the frame is destined to. Thus XDP works for both interfaces, that allows to test xdp redirect between two interfaces easily. Also, each rx queue have own page pools, but common for both netdevs. XDP prog is common for all channels till appropriate changes are added in XDP infrastructure. Also, once page_pool recycling becomes part of skb netstack some simplifications can be added, like removing page_pool_release_page() before skb receive. In order to keep rx_dev while redirect, that can be somehow used in future, do flush in rx_handler, that allows to keep rx dev the same while redirect. It allows to conform with tracing rx_dev pointed by Jesper. Also, there is probability, that XDP generic code can be extended to support multi ndev drivers like this one, using same rx queue for several ndevs, based on switchdev for instance or else. In this case, driver can be modified like exposed here: https://lkml.org/lkml/2019/7/3/243Acked-by: NJesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: NIvan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: NDavid S.

That's possible to set channel num while interfaces are down. When interface gets up it should resplit budget. This resplit can happen after phy is up but only if speed is changed, so should be set before this, for this allow it to happen while changing number of channels, when interfaces are down.

That's possible to set ring params while interfaces are down. When interface gets up it uses number of descs to fill rx queue and on later on changes to create rx pools. Usually, this resplit can happen after phy is up, but it can be needed before this, so allow it to happen while setting number of rx descs, when interfaces are down. Also, if no dependency on intf state, move it to cpdma layer, where it should be. Signed-off-by: NIvan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Ivan Khoronzhuk 提交于
Jesper recently removed page_pool_destroy() (from driver invocation) and moved shutdown and free of page_pool into xdp_rxq_info_unreg(), in-order to handle in-flight packets/pages. This created an asymmetry in drivers create/destroy pairs. This patch reintroduce page_pool_destroy and add page_pool user refcnt. This serves the purpose to simplify drivers error handling as driver now drivers always calls page_pool_destroy() and don't need to track if xdp_rxq_info_reg_mem_model() was unsuccessful. This could be used for a special cases where a single RX-queue (with a single page_pool) provides packets for two net_device'es, and thus needs to register the same page_pool twice with two xdp_rxq_info structures. This patch is primarily to ease API usage for drivers. The recently merged netsec driver, actually have a bug in this area, which is solved by this API change. This patch is a modified version of Ivan Khoronzhuk's original patch.

BLE based 6LoWPAN networks are highly constrained in bandwidth. Do not take a short-cut, always check if the destination address is known to belong to a peer. As a side-effect this also removes any behavioral differences between one, and two or more connected peers.

Like any IPv6 capable device, 6LNs can have multiple addresses assigned using SLAAC and made known through neighbour advertisements. After checking the destination address against all peers link-local addresses, consult the neighbour cache for additional known addresses. RFC7668 defines the scope of Neighbor Advertisements in Section 3.2.3: 1. "A Bluetooth LE 6LN MUST NOT register its link-local address" 2. "A Bluetooth LE 6LN MUST register its non-link-local addresses with the 6LBR by sending Neighbor Solicitation (NS) messages ..." Due to these constranits both the link-local addresses tracked in the list of 6lowpan peers, and the neighbour cache have to be used when identifying the 6lowpan peer for a destination address.

Handle overlooked case where the target address is assigned to a peer and neither route nor gateway exist. For one peer, no checks are performed to see if it is meant to receive packets for a given address. As soon as there is a second peer however, checks are performed to deal with routes and gateways for handling complex setups with multiple hops to a target address. This logic assumed that no route and no gateway imply that the destination address can not be reached, which is false in case of a direct peer.

Microsoft Surface Precision Mouse provides bogus identity address when pairing. It connects with Static Random address but provides Public Address in SMP Identity Address Information PDU. Address has same value but type is different. Workaround this by dropping IRK if ID address discrepancy is detected. > HCI Event: LE Meta Event (0x3e) plen 19 LE Connection Complete (0x01) Status: Success (0x00) Handle: 75 Role: Master (0x00) Peer address type: Random (0x01) Peer address: E0:52:33:93:3B:21 (Static) Connection interval: 50.00 msec (0x0028) Connection latency: 0 (0x0000) Supervision timeout: 420 msec (0x002a) Master clock accuracy: 0x00 .... > ACL Data RX: Handle 75 flags 0x02 dlen 12 SMP: Identity Address Information (0x09) len 7 Address type: Public (0x00) Address: E0:52:33:93:3B:21 Signed-off-by: NSzymon Janc <szymon.janc@codecoup.pl> Tested-by: NMaarten Fonville <maarten.fonville@gmail.com> Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=199461 Cc: stable@vger.kernel.org Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

The spec defines PSM and LE_PSM as different domains so a listen on the same PSM is valid if the address type points to a different bearer. Signed-off-by: NLuiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>
