2023-02-15bpf: Zeroing allocated object from slab in bpf memory allocatorHou Tao
Currently the freed element in bpf memory allocator may be immediately reused, for htab map the reuse will reinitialize special fields in map value (e.g., bpf_spin_lock), but lookup procedure may still access these special fields, and it may lead to hard-lockup as shown below: NMI backtrace for cpu 16 CPU: 16 PID: 2574 Comm: htab.bin Tainted: G L 6.1.0+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), RIP: 0010:queued_spin_lock_slowpath+0x283/0x2c0 ...... Call Trace: <TASK> copy_map_value_locked+0xb7/0x170 bpf_map_copy_value+0x113/0x3c0 __sys_bpf+0x1c67/0x2780 __x64_sys_bpf+0x1c/0x20 do_syscall_64+0x30/0x60 entry_SYSCALL_64_after_hwframe+0x46/0xb0 ...... </TASK> For htab map, just like the preallocated case, these is no need to initialize these special fields in map value again once these fields have been initialized. For preallocated htab map, these fields are initialized through __GFP_ZERO in bpf_map_area_alloc(), so do the similar thing for non-preallocated htab in bpf memory allocator. And there is no need to use __GFP_ZERO for per-cpu bpf memory allocator, because __alloc_percpu_gfp() does it implicitly. Fixes: 0fd7c5d43339 ("bpf: Optimize call_rcu in non-preallocated hash map.")

2023-02-15virtio-blk: add support for zoned block devicesDmitry Fomichev
This patch adds support for Zoned Block Devices (ZBDs) to the kernel virtio-blk driver. The patch accompanies the virtio-blk ZBD support draft that is now being proposed for standardization. The latest version of the draft is linked at https://github.com/oasis-tcs/virtio-spec/issues/143 . The QEMU zoned device code that implements these protocol extensions has been developed by Sam Li and it is currently in review at the QEMU mailing list. A number of virtblk request structure changes has been introduced to accommodate the functionality that is specific to zoned block devices and, most importantly, make room for carrying the Zoned Append sector value from the device back to the driver along with the request status. The zone-specific code in the patch is heavily influenced by NVMe ZNS code in drivers/nvme/host/zns.c, but it is simpler because the proposed virtio ZBD draft only covers the zoned device features that are relevant to the zoned functionality provided by Linux block layer. includes the following fixup: virtio-blk: fix probe without CONFIG_BLK_DEV_ZONED When building without CONFIG_BLK_DEV_ZONED, VIRTIO_BLK_F_ZONED is excluded from array of driver features. As a result virtio_has_feature panics in virtio_check_driver_offered_feature since that by design verifies that a feature we are checking for is listed in the feature array. To fix, replace the call to virtio_has_feature with a stub.

2023-02-14NFS: Convert buffered writes to use foliosTrond Myklebust
Mostly mechanical conversion of struct page and functions into struct folio equivalents. The lack of support for folios in write_cache_pages(), means we still only support order 0 folio allocations. However the rest of the writeback code should now be ready for order n > 0. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
2023-02-14NFS: Convert buffered reads to use foliosTrond Myklebust
Perform a largely mechanical conversion of references to struct page and page-specific functions to use the folio equivalents. Note that the fscache functionality remains untouched. Instead we just pass in the folio page. This should be OK, as long as we use order 0 folios together with fscache.

Xilinx PG158 page 80 [1] states that master transaction inhibit bit must be set to properly setup the transaction in QSPI mode. Add the force_irq flag to follow this sequence.

2023-02-14rpmsg: glink: smem: Wrap driver contextBjorn Andersson
The Glink SMEM driver allocates a struct device and hangs two devres-allocated pipe objects thereon. To facilitate the move of interrupt and mailbox handling to the driver, introduce a wrapper object capturing the device, glink reference and remote processor id. The type of the remoteproc reference is updated, as these are specifically targeting the SMEM implementation.

2023-02-14spi: Reorder fields in 'struct spi_transfer'Christophe JAILLET
Group some variables based on their sizes to reduce hole and avoid padding. On x86_64, this shrinks the size from 144 to 128 bytes. Turn 'timestamped' into a bitfield so that it can be easily merged with some other bifields and move 'error'. This should have no real impact on memory allocation because 'struct spi_transfer' is mostly used on stack, but it can save a few cycles when the structure is initialized or copied.

2023-02-14wifi: cfg80211: call reg_notifier for self managed wiphy from driver hintWen Gong
Currently the regulatory driver does not call the regulatory callback reg_notifier for self managed wiphys. Sometimes driver needs cfg80211 to calculate the info of ieee80211_channel such as flags and power, and driver needs to get the info of ieee80211_channel after hint of driver, but driver does not know when calculation of the info of ieee80211_channel become finished, so add notify to driver in reg_process_self_managed_hint() from cfg80211 is a good way, then driver could get the correct info in callback of reg_notifier.
