2020-05-30sch_cake: Take advantage of skb->hash where appropriateToke Høiland-Jørgensen
While the other fq-based qdiscs take advantage of skb->hash and doesn't recompute it if it is already set, sch_cake does not. This was a deliberate choice because sch_cake hashes various parts of the packet header to support its advanced flow isolation modes. However, foregoing the use of skb->hash entirely loses a few important benefits: - When skb->hash is set by hardware, a few CPU cycles can be saved by not hashing again in software. - Tunnel encapsulations will generally preserve the value of skb->hash from before the encapsulation, which allows flow-based qdiscs to distinguish between flows even though the outer packet header no longer has flow information. It turns out that we can preserve these desirable properties in many cases, while still supporting the advanced flow isolation properties of sch_cake. This patch does so by reusing the skb->hash value as the flow_hash part of the hashing procedure in cake_hash() only in the following conditions: - If the skb->hash is marked as covering the flow headers (skb->l4_hash is set) AND - NAT header rewriting is either disabled, or did not change any values used for hashing. The latter is important to match local-origin packets such as those of a tunnel endpoint. The immediate motivation for fixing this was the recent patch to WireGuard to preserve the skb->hash on encapsulation. As such, this is also what I tested against; with this patch, added latency under load for competing flows drops from ~8 ms to sub-1ms on an RRUL test over a WireGuard tunnel going through a virtual link shaped to 1Gbps using sch_cake. This matches the results we saw with a similar setup using sch_fq_codel when testing the WireGuard patch.

2020-05-30ravb: Mask PHY mode to avoid inserting delays twiceGeert Uytterhoeven
Until recently, the Micrel KSZ9031 PHY driver ignored any PHY mode ("RGMII-*ID") settings, but used the hardware defaults, augmented by explicit configuration of individual skew values using the "*-skew-ps" DT properties. The lack of PHY mode support was compensated by the EtherAVB MAC driver, which configures TX and/or RX internal delay itself, based on the PHY mode. However, now the KSZ9031 driver has gained PHY mode support, delays may be configured twice, causing regressions. E.g. on the Renesas Salvator-X board with R-Car M3-W ES1.0, TX performance dropped from ca. 400 Mbps to 0.1-0.3 Mbps, as measured by nuttcp. As internal delay configuration supported by the KSZ9031 PHY is too limited for some use cases, the ability to configure MAC internal delay is deemed useful and necessary. Hence a proper fix would involve splitting internal delay configuration in two parts, one for the PHY, and one for the MAC. However, this would require adding new DT properties, thus breaking DTB backwards-compatibility. Hence fix the regression in a backwards-compatibility way, by letting the EtherAVB driver mask the PHY mode when it has inserted a delay, to avoid the PHY driver adding a second delay. This also fixes messages like: Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00: *-skew-ps values should be used only with phy-mode = "rgmii" as the PHY no longer sees the original RGMII-*ID mode. Solving the issue by splitting configuration in two parts can be handled in future patches, and would require retaining a backwards-compatibility mode anyway.

2020-05-30Merge branch 'selftests-forwarding-Two-small-changes'David S. Miller
Petr Machata says: ==================== selftests: forwarding: Two small changes Two unrelated changes in this patchset: - In patch #1, convert mirror tests from using ping directly to generating ICMP packets by mausezahn. Using ping in tests is error-prone, because ping is too smart. On a flaky system (notably in a simulator), when packets don't come quickly enough, more pings are sent, and that throws off counters. This was worked around in the past by just pinging more slowly, but using mausezahn avoids the issue as well without making the tests unnecessary slow. - A missing stats_update callback was recently added to act_pedit. Now that iproute2 supports JSON dumping for pedit, extend in patch #2 the pedit_dsfield selftest with a check that would have caught the fact that the callback was missing. ==================== Signed-off-by: David S.

Anirudh (Ani) adds a poll for reset completion before proceeding with driver initialization when the DDP package fails to load and the firmware issues a core reset. Jake cleans up unnecessary code, since ice_set_dflt_vsi_ctx() performs a memset to clear the info from the context structures. Fixed a potential double free during probe unrolling after a failure. Also fixed a potential NULL pointer dereference upon register_netdev() failure. Tony makes two functions static which are not called outside of their file. Brett refactors the ice_ena_vf_mappings(), which was doing the VF's MSIx and queue mapping in one function which was hard to digest. So create a new function to handle the enabling MSIx mappings and another function to handle the enabling of queue mappings. Simplify the code flow in ice_sriov_configure(). Created a helper function for clearing VPGEN_VFRTRIG register, as this needs to be done on reset to notify the VF that we are done resetting it. Fixed the initialization/creation and reset flows, which was unnecessarily complicated, so separate the two flows into their own functions. Renamed VF initialization functions to make it more clear what they do and why. Added functionality to set the VF trust mode bit on reset. Added helper functions to rebuild the VLAN and MAC configurations when resetting a VF. Refactored how the VF reset is handled to prevent VF reset timeouts.

2020-05-30net: qrtr: Allocate workqueue before kernel_bindChris Lew
A null pointer dereference in qrtr_ns_data_ready() is seen if a client opens a qrtr socket before qrtr_ns_init() can bind to the control port. When the control port is bound, the ENETRESET error will be broadcasted and clients will close their sockets. This results in DEL_CLIENT packets being sent to the ns and qrtr_ns_data_ready() being called without the workqueue being allocated. Allocate the workqueue before setting sk_data_ready and binding to the control port. This ensures that the work and workqueue structs are allocated and initialized before qrtr_ns_data_ready can be called.

Currently we remote the msk from the token container only via mptcp_close(). The MPTCP master socket can be destroyed also via other paths (e.g. if not yet accepted, when shutting down the listener socket). When we hit the latter scenario, dangling msk references are left into the token container, leading to memory corruption and/or UaF.

If the 3whs is completed and the 'can_ack' flag is already set, the latter will fail with -EINVAL.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO fixes from Linus Walleij: "Here are some (very) late fixes for GPIO, none of them very serious except the one tagged for stable for enabling IRQ on open drain lines: - Fix probing of mvebu chips without PWM - Fix error path on ida_get_simple() on the exar driver - Notify userspace properly about line status changes when flags are changed on lines. - Fix a sleeping while holding spinlock in the mellanox driver. - Fix return value of the PXA and Kona probe calls. - Fix IRQ locking of open drain lines, it is fine to have IRQs on open drain lines flagged for output" * tag 'gpio-v5.7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio: fix locking open drain IRQ lines gpio: bcm-kona: Fix return value of bcm_kona_gpio_probe() gpio: pxa: Fix return value of pxa_gpio_probe() gpio: mlxbf2: Fix sleeping while holding spinlock gpiolib: notify user-space about line status changes after flags are set gpio: exar: Fix bad handling for ida_simple_get error path gpio: mvebu: Fix probing for chips without PWM
