2021-08-17drm: Copy drm_wait_vblank to user before returningMark Yacoub
[Why] Userspace should get back a copy of drm_wait_vblank that's been modified even when drm_wait_vblank_ioctl returns a failure. Rationale: drm_wait_vblank_ioctl modifies the request and expects the user to read it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates the sequence to become current_vblank_count + sequence (which was RELATIVE), but now it became ABSOLUTE. drmWaitVBlank (in libdrm) expects this to be the case as it modifies the request to be Absolute so it expects the sequence to would have been updated. The change is in compat_drm_wait_vblank, which is called by drm_compat_ioctl. This change of copying the data back regardless of the return number makes it en par with drm_ioctl, which always copies the data before returning. [How] Return from the function after everything has been copied to user.

As follow-up to the discussion with Jakub Kicinski about iavf locking being insufficient [1] convert iavf to use mutexes instead of bitops. The locking logic is kept as is, just a drop-in replacement of enum iavf_critical_section_t with separate mutexes. The only difference is that the mutexes will be destroyed before the module is unloaded.

2021-08-17mtd: mtdconcat: Judge callback existence based on the masterZhihao Cheng
Since commit 46b5889cc2c5("mtd: implement proper partition handling") applied, mtd partition device won't hold some callback functions, such as _block_isbad, _block_markbad, etc. Besides, function mtd_block_isbad() will get mtd device's master mtd device, then invokes master mtd device's callback function. So, following process may result mtd_block_isbad() always return 0, even though mtd device has bad blocks: 1. Split a mtd device into 3 partitions: PA, PB, PC [ Each mtd partition device won't has callback function _block_isbad(). ] 2. Concatenate PA and PB as a new mtd device PN [ mtd_concat_create() finds out each subdev has no callback function _block_isbad(), so PN won't be assigned callback function concat_block_isbad(). ] Then, mtd_block_isbad() checks "!master->_block_isbad" is true, will always return 0.

2021-08-17mtd: rfd_ftl: add discard supportSean Young
I proposed this change 16 years ago before discard was a feature in the block layer: https://lwn.net/Articles/162776/ Now that the block layer has discard, we can finally merge this change. Discard is also known as trim. By implementing discard, both fstrim and the discard filesystem option can be used. Implementing discard in the ftl means that when files are removed, there is less data in the ftl mapping. This means less stuff to move around for erasing and also less erasing to do; this means improved wear levelling and improved performance.

2021-08-17mtdblock: Warn if added for a NAND deviceEzequiel Garcia
There is a surprisingly large number of tutorials that suggest using mtdblock to mount SquashFS filesystems on flash devices, including NAND devices. This approach is suboptimal than using UBI. If the flash device is NAND, this is specially true, due to wear leveling, bit-flips and badblocks. In this case UBI is strongly preferred, so be nice to users and print a warning suggesting to consider UBI block, if mtdblock is added for a NAND device.

2021-08-17virtio-net: use NETIF_F_GRO_HW instead of NETIF_F_LROJason Wang
Commit a02e8964eaf92 ("virtio-net: ethtool configurable LRO") maps LRO to virtio guest offloading features and allows the administrator to enable and disable those features via ethtool. This leads to several issues: - For a device that doesn't support control guest offloads, the "LRO" can't be disabled triggering WARN in dev_disable_lro() when turning off LRO or when enabling forwarding bridging etc. - For a device that supports control guest offloads, the guest offloads are disabled in cases of bridging, forwarding etc slowing down the traffic. Fix this by using NETIF_F_GRO_HW instead. Though the spec does not guarantee packets to be re-segmented as the original ones, we can add that to the spec, possibly with a flag for devices to differentiate between GRO and LRO. Further, we never advertised LRO historically before a02e8964eaf92 ("virtio-net: ethtool configurable LRO") and so bridged/forwarded configs effectively always relied on virtio receive offloads behaving like GRO - thus even if this breaks any configs it is at least not a regression.

2021-08-17octeontx2-af: configure npc for cn10k to allow packets from cptVidya
On CN10K, the higher bits in the channel number represents the CPT channel number. Mask out these higher bits in the npc configuration to allow packets from cpt for parsing.

The way SW can identify the number NPC counters supported by silicon has changed for CN10K. This patch addresses this reading appropriate registers to find out number of counters available.

2021-08-17octeontx2-af: Allocate low priority entries for PFSubbaraya Sundeep
If the mcam entry allocation request is from PF and NOT a priority allocation request then allocate low priority entries so that PF entries always have lower priority than its VFs. This is required so that entries with (base) MCAM match criteria have lower priority compared to entries with (base + additional) match criteria. This patch considers only best case scenario where PF entries are allocated from low priority zone if low priority zone has free space. There are worst case scenarios like: 1. VFs allocating hundreds of MCAM entries leading to VFs using all mid priority zone and low priority zone entries hence no entries free from low priority zone for PF. 2. All the PFs and VFs in the system allocating and freeing entries causing fragmentation in MCAM space and all the entries requested by PF could not fit in low priority zone for allocation. This patch do not handle worst case scenarios. Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2021-08-17octeontx2-pf: Unify flow management variablesSunil Goutham
Variables used for TC flow management like maximum number of flows, number of flows installed etc are a copy of ntuple flow management variables. Since both TC and NTUPLE are not supported at the same time, it's better to unify these with common variables. This patch addresses this unification and also does cleanup of other minor stuff wrt TC.
