Sudarsana Reddy Kalluru says: ==================== qed*: Add support for pcie advanced error recovery. The patch series adds qed/qede driver changes for PCIe Advanced Error Recovery (AER) support. Patch (1) adds qed changes to enable the device to send error messages to root port when detected. Patch (2) adds qede support for handling the detected errors (AERs). Changes from previous version: ------------------------------- v2: use pci_num_vf() instead of caching the value in edev. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-04-23qede: Add support for handling the pcie errors.Sudarsana Reddy Kalluru
The error recovery is handled by management firmware (MFW) with the help of qed/qede drivers. Upon detecting the errors, driver informs MFW about this event which in turn starts a recovery process. MFW sends ERROR_RECOVERY notification to the driver which performs the required cleanup/recovery from the driver side.

2020-04-23mlxsw: Fix some IS_ERR() vs NULL bugsDan Carpenter
The mlxsw_sp_acl_rulei_create() function is supposed to return an error pointer from mlxsw_afa_block_create(). The problem is that these functions both return NULL instead of error pointers. Half the callers expect NULL and half expect error pointers so it could lead to a NULL dereference on failure. This patch changes both of them to return error pointers and changes all the callers which checked for NULL to check for IS_ERR() instead.

2020-04-23net: dsa: add GRO support via gro_cellsAlexander Lobakin
gro_cells lib is used by different encapsulating netdevices, such as geneve, macsec, vxlan etc. to speed up decapsulated traffic processing. CPU tag is a sort of "encapsulation", and we can use the same mechs to greatly improve overall DSA performance. skbs are passed to the GRO layer after removing CPU tags, so we don't need any new packet offload types as it was firstly proposed by me in the first GRO-over-DSA variant [1]. The size of struct gro_cells is sizeof(void *), so hot struct dsa_slave_priv becomes only 4/8 bytes bigger, and all critical fields remain in one 32-byte cacheline. The other positive side effect is that drivers for network devices that can be shipped as CPU ports of DSA-driven switches can now use napi_gro_frags() to pass skbs to kernel. Packets built that way are completely non-linear and are likely being dropped without GRO. This was tested on to-be-mainlined-soon Ethernet driver that uses napi_gro_frags(), and the overall performance was on par with the variant from [1], sometimes even better due to minimal overhead. net.core.gro_normal_batch tuning may help to push it to the limit on particular setups and platforms. iperf3 IPoE VLAN NAT TCP forwarding (port1.218 -> port0) setup on 1.2 GHz MIPS board: 5.7-rc2 baseline: [ID] Interval Transfer Bitrate Retr [ 5] 0.00-120.01 sec 9.00 GBytes 644 Mbits/sec 413 sender [ 5] 0.00-120.00 sec 8.99 GBytes 644 Mbits/sec receiver Iface RX packets TX packets eth0 7097731 7097702 port0 426050 6671829 port1 6671681 425862 port1.218 6671677 425851 With this patch: [ID] Interval Transfer Bitrate Retr [ 5] 0.00-120.01 sec 12.2 GBytes 870 Mbits/sec 122 sender [ 5] 0.00-120.00 sec 12.2 GBytes 870 Mbits/sec receiver Iface RX packets TX packets eth0 9474792 9474777 port0 455200 353288 port1 9019592 455035 port1.218 353144 455024 v2: - Add some performance examples in the commit message; - No functional changes.

2020-04-23ipv6: Honor all IPv6 PIO Valid Lifetime valuesFernando Gont
RFC4862 5.5.3 e) prevents received Router Advertisements from reducing the Valid Lifetime of configured addresses to less than two hours, thus preventing hosts from reacting to the information provided by a router that has positive knowledge that a prefix has become invalid. This patch makes hosts honor all Valid Lifetime values, as per draft-gont-6man-slaac-renum-06, Section 4.2. This is meant to help mitigate the problem discussed in draft-ietf-v6ops-slaac-renum. Note: Attacks aiming at disabling an advertised prefix via a Valid Lifetime of 0 are not really more harmful than other attacks that can be performed via forged RA messages, such as those aiming at completely disabling a next-hop router via an RA that advertises a Router Lifetime of 0, or performing a Denial of Service (DoS) attack by advertising illegitimate prefixes via forged PIOs. In scenarios where RA-based attacks are of concern, proper mitigations such as RA-Guard [RFC6105] [RFC7113] should be implemented.

2020-04-23null_blk: Fix zoned command handlingDamien Le Moal
For write operations issued to a null_blk device with zoned mode enabled, the state and write pointer position of the zone targeted by the command should be checked before badblocks and memory backing are handled as the write may be first failed due to, for instance, a sector position not aligned with the zone write pointer. This order of checking for errors reflects more accuratly the behavior of physical zoned devices. Furthermore, the write pointer position of the target zone should be incremented only and only if no errors are reported by badblocks and memory backing handling. To fix this, introduce the small helper function null_process_cmd() which execute null_handle_badblocks() and null_handle_memory_backed() and use this function in null_zone_write() to correctly handle write requests to zoned null devices depending on the type and state of the write target zone. Also call this function in null_handle_zoned() to process read requests to zoned null devices. null_process_cmd() is called directly from null_handle_cmd() for regular null devices, resulting in no functional change for these type of devices. To have symmetric names, the function null_handle_zoned() is renamed to null_process_zoned_cmd().

2020-04-23ALSA: hda: Always use jackpoll helper for jack update after resumeTakashi Iwai
HD-audio codec driver applies a tricky procedure to forcibly perform the runtime resume by mimicking the usage count even if the device has been runtime-suspended beforehand. This was needed to assure to trigger the jack detection update after the system resume. And recently we also applied the similar logic to the HD-audio controller side. However this seems leading to some inconsistency, and eventually PCI controller gets screwed up. This patch is an attempt to fix and clean up those behavior: instead of the tricky runtime resume procedure, the existing jackpoll work is scheduled when such a forced codec resume is required. The jackpoll work will power up the codec, and this alone should suffice for the jack status update in usual cases. If the extra polling is requested (by checking codec->jackpoll_interval), the manual update is invoked after that, and the codec is powered down again. Also, we filter the spurious wake up of the codec from the controller runtime resume by checking codec->relaxed_resume flag. If this flag is set, basically we don't need to wake up explicitly, but it's supposed to be done via the audio component notifier.

2020-04-23ALSA: usb-audio: Fix usb audio refcnt leak when getting spdifXiyu Yang
snd_microii_spdif_default_get() invokes snd_usb_lock_shutdown(), which increases the refcount of the snd_usb_audio object "chip". When snd_microii_spdif_default_get() returns, local variable "chip" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in several exception handling paths of snd_microii_spdif_default_get(). When those error scenarios occur such as usb_ifnum_to_if() returns NULL, the function forgets to decrease the refcnt increased by snd_usb_lock_shutdown(), causing a refcnt leak. Fix this issue by jumping to "end" label when those error scenarios occur.

2020-04-22Merge branch 'dpaa2-eth-add-support-for-xdp-bulk-enqueue'David S. Miller
Ioana Ciornei says: ==================== dpaa2-eth: add support for xdp bulk enqueue The first patch moves the DEV_MAP_BULK_SIZE macro into the xdp.h header file so that drivers can take advantage of it and use it. The following 3 patches are there to setup the scene for using the bulk enqueue feature. First of all, the prototype of the enqueue function is changed so that it returns the number of enqueued frames. Second, the bulk enqueue interface is used but without any functional changes, still one frame at a time is enqueued. Third, the .ndo_xdp_xmit callback is split into two stages, create all FDs for the xdp_frames received and then enqueue them. The last patch of the series builds on top of the others and instead of issuing an enqueue operation for each FD it issues a bulk enqueue call for as many frames as possible. This is repeated until all frames are enqueued or the maximum number of retries is hit. We do not use the XDP_XMIT_FLUSH flag since the architecture is not capable to store all frames dequeued in a NAPI cycle, instead we send out right away all frames received in a .ndo_xdp_xmit call. Changes in v2: - statically allocate an array of dpaa2_fd by frame queue - use the DEV_MAP_BULK_SIZE as the maximum number of xdp_frames received in .ndo_xdp_xmit() ==================== Signed-off-by: David S.

2020-04-22mptcp: fix data_fin handing in RX pathPaolo Abeni
The data fin flag is set only via a DSS option, but mptcp_incoming_options() copies it unconditionally from the provided RX options. Since we do not clear all the mptcp sock RX options in a socket free/alloc cycle, we can end-up with a stray data_fin value while parsing e.g. MPC packets. That would lead to mapping data corruption and will trigger a few WARN_ON() in the RX path. Instead of adding a costly memset(), fetch the data_fin flag only for DSS packets - when we always explicitly initialize such bit at option parsing time.

2020-04-22net: phy: tja11xx: add delayed registration of TJA1102 PHY1Oleksij Rempel
TJA1102 is a dual PHY package with PHY0 having proper PHYID and PHY1 having no ID. On one hand it is possible to for PHY detection by compatible, on other hand we should be able to reset complete chip before PHY1 configured it, and we need to define dependencies for proper power management. We can solve it by defining PHY1 as child of PHY0: tja1102_phy0: ethernet-phy@4 { reg = <0x4>; interrupts-extended = <&gpio5 8 IRQ_TYPE_LEVEL_LOW>; reset-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>; reset-assert-us = <20>; reset-deassert-us = <2000>; tja1102_phy1: ethernet-phy@5 { reg = <0x5>; interrupts-extended = <&gpio5 8 IRQ_TYPE_LEVEL_LOW>; }; }; The PHY1 should be a subnode of PHY0 and registered only after PHY0 was completely reset and initialized.

2020-04-22net: phy: micrel: add phy-mode support for the KSZ9031 PHYOleksij Rempel
Add support for following phy-modes: rgmii, rgmii-id, rgmii-txid, rgmii-rxid. This PHY has an internal RX delay of 1.2ns and no delay for TX. The pad skew registers allow to set the total TX delay to max 1.38ns and the total RX delay to max of 2.58ns (configurable 1.38ns + build in 1.2ns) and a minimal delay of 0ns. According to the RGMII v1.3 specification the delay provided by PCB traces should be between 1.5ns and 2.0ns. The RGMII v2.0 allows to provide this delay by MAC or PHY. So, we configure this PHY to the best values we can get by this HW: TX delay to 1.38ns (max supported value) and RX delay to 1.80ns (best calculated delay) The phy-modes can still be fine tuned/overwritten by *-skew-ps device tree properties described in: Documentation/devicetree/bindings/net/micrel-ksz90x1.txt Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Philippe Schenker <philippe.schenker@toradex.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
