2023-02-16io_uring: Support calling io_uring_register with a registered ring fdJosh Triplett
Add a new flag IORING_REGISTER_USE_REGISTERED_RING (set via the high bit of the opcode) to treat the fd as a registered index rather than a file descriptor. This makes it possible for a library to open an io_uring, register the ring fd, close the ring fd, and subsequently use the ring entirely via registered index.

2023-02-16tty: n_gsm: add keep alive supportDaniel Starke
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010. See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516 The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to the newer 27.010 here. Chapters 5.4.6.3.4 and 5.1.8.1.3 describe the test command which can be used to test the mux connection between both sides. Currently, no algorithm is implemented to make use of this command. This requires that each multiplexed upper layer protocol supervises the underlying muxer connection to handle possible connection losses. Introduce ioctl commands and functions to optionally enable keep alive handling via the test command as described in chapter 5.4.6.3.4. A single incrementing octet "ka_num" is being used for unique identification of each single keep alive packet. Retries will use the same "ka_num" value as the original packet. Retry count and interval are taken from the general parameters N2 and T2. Add usage description and basic example for the new ioctl to the n_gsm documentation. Note that support for the test command is mandatory and already present in the muxer implementation since the very first version. Also note that the previous ioctl structure gsm_config cannot be extended due to missing checks against zero of the field "unused".

2023-02-16devlink: Fix netdev notifier chain corruptionIdo Schimmel
Cited commit changed devlink to register its netdev notifier block on the global netdev notifier chain instead of on the per network namespace one. However, when changing the network namespace of the devlink instance, devlink still tries to unregister its notifier block from the chain of the old namespace and register it on the chain of the new namespace. This results in corruption of the notifier chains, as the same notifier block is registered on two different chains: The global one and the per network namespace one. In turn, this causes other problems such as the inability to dismantle namespaces due to netdev reference count issues. Fix by preventing devlink from moving its notifier block between namespaces. Reproducer: # echo "10 1" > /sys/bus/netdevsim/new_device # ip netns add test123 # devlink dev reload netdevsim/netdevsim10 netns test123 # ip netns del test123 [ 71.935619] unregister_netdevice: waiting for lo to become free.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-02-10 1) From Roi and Mark: MultiPort eswitch support MultiPort E-Switch builds on newer hardware's capabilities and introduces a mode where a single E-Switch is used and all the vports and physical ports on the NIC are connected to it. The new mode will allow in the future a decrease in the memory used by the driver and advanced features that aren't possible today. This represents a big change in the current E-Switch implantation in mlx5. Currently, by default, each E-Switch manager manages its E-Switch. Steering rules in each E-Switch can only forward traffic to the native physical port associated with that E-Switch. While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort Eswitch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default. 2) From Jiri: Improvements and fixes for mlx5 netdev's devlink logic 2.1) Cleanups related to mlx5's devlink port logic 2.2) Move devlink port registration to be done before netdev alloc 2.3) Create auxdev devlink instance in the same ns as parent devlink 2.4) Suspend auxiliary devices only in case of PCI device suspend * tag 'mlx5-updates-2023-02-10' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Suspend auxiliary devices only in case of PCI device suspend net/mlx5: Remove "recovery" arg from mlx5_load_one() function net/mlx5e: Create auxdev devlink instance in the same ns as parent devlink net/mlx5e: Move devlink port registration to be done before netdev alloc net/mlx5e: Move dl_port to struct mlx5e_dev net/mlx5e: Replace usage of mlx5e_devlink_get_dl_port() by netdev->devlink_port net/mlx5e: Pass mdev to mlx5e_devlink_port_register() net/mlx5: Remove outdated comment net/mlx5e: TC, Remove redundant parse_attr argument net/mlx5e: Use a simpler comparison for uplink rep net/mlx5: Lag, Add single RDMA device in multiport mode net/mlx5: Lag, set different uplink vport metadata in multiport eswitch mode net/mlx5: E-Switch, rename bond update function to be reused net/mlx5e: TC, Add peer flow in mpesw mode net/mlx5: Lag, Control MultiPort E-Switch single FDB mode ==================== Link: https://lore.kernel.org/r/20230214221239.159033-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

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.

2023-02-15net: no longer support SOCK_REFCNT_DEBUG featureJason Xing
Commit e48c414ee61f ("[INET]: Generalise the TCP sock ID lookup routines") commented out the definition of SOCK_REFCNT_DEBUG in 2005 and later another commit 463c84b97f24 ("[NET]: Introduce inet_connection_sock") removed it. Since we could track all of them through bpf and kprobe related tools and the feature could print loads of information which might not be that helpful even under a little bit pressure, the whole feature which has been inactive for many years is no longer supported.

By default the CXL RAS mask registers bits are defaulted to 1's and suppress all error reporting. If the kernel has negotiated ownership of error handling for CXL then unmask the mask registers by writing 0s. PCI_EXP_DEVCTL capability is checked to see uncorrectable or correctable errors bits are set before unmasking the respective errors.
