2024-08-12nsfs: fix ioctl declarationChristian Brauner
The kernel is writing an object of type __u64, so the ioctl has to be defined to _IOR(NSIO, 0x5, __u64) instead of _IO(NSIO, 0x5). Reported-by: Dmitry V. Levin <ldv@strace.io> Link: https://lore.kernel.org/r/20240730164554.GA18486@altlinux.org Signed-off-by: Christian Brauner <brauner@kernel.org>
2024-08-12lsm: add the inode_free_security_rcu() LSM implementation hookPaul Moore
The LSM framework has an existing inode_free_security() hook which is used by LSMs that manage state associated with an inode, but due to the use of RCU to protect the inode, special care must be taken to ensure that the LSMs do not fully release the inode state until it is safe from a RCU perspective. This patch implements a new inode_free_security_rcu() implementation hook which is called when it is safe to free the LSM's internal inode state. Unfortunately, this new hook does not have access to the inode itself as it may already be released, so the existing inode_free_security() hook is retained for those LSMs which require access to the inode.

2024-08-12ethtool: rss: don't report key if device doesn't support itJakub Kicinski
marvell/otx2 and mvpp2 do not support setting different keys for different RSS contexts. Contexts have separate indirection tables but key is shared with all other contexts. This is likely fine, indirection table is the most important piece. Don't report the key-related parameters from such drivers. This prevents driver-errors, e.g. otx2 always writes the main key, even when user asks to change per-context key. The second reason is that without this change tracking the keys by the core gets complicated. Even if the driver correctly reject setting key with rss_context != 0, change of the main key would have to be reflected in the XArray for all additional contexts. Since the additional contexts don't have their own keys not including the attributes (in Netlink speak) seems intuitive. ethtool CLI seems to deal with it just fine. Having to set the flag in majority of the drivers is a bit tedious but not reporting the key is a safer default.

2024-08-12ethtool: make ethtool_ops::cap_rss_ctx_supported optionalJakub Kicinski
cap_rss_ctx_supported was created because the API for creating and configuring additional contexts is mux'ed with the normal RSS API. Presence of ops does not imply driver can actually support rss_context != 0 (in fact drivers mostly ignore that field). cap_rss_ctx_supported lets core check that the driver is context-aware before calling it. Now that we have .create_rxfh_context, there is no such ambiguity. We can depend on presence of the op. Make setting the bit optional.

This commit fixes two problems with the original definitions: 1) There wasn't an empty version of these functions 2) The #if only depended on CONFIG_ACPI. But the functions are implemented in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real functions to exist.

2024-08-11RDMA/mlx5: Add support for DMABUF MR registrations with Data-directYishai Hadas
Add support for DMABUF MR registrations with Data-direct device. Upon userspace calling to register a DMABUF MR with the data direct bit set, the below algorithm will be followed. 1) Obtain a pinned DMABUF umem from the IB core using the user input parameters (FD, offset, length) and the DMA PF device. The DMA PF device is needed to allow the IOMMU to enable the DMA PF to access the user buffer over PCI. 2) Create a KSM MKEY by setting its entries according to the user buffer VA to IOVA mapping, with the MKEY being the data direct device-crossed MKEY. This KSM MKEY is umrable and will be used as part of the MR cache. The PD for creating it is the internal device 'data direct' kernel one. 3) Create a crossing MKEY that points to the KSM MKEY using the crossing access mode. 4) Manage the KSM MKEY by adding it to a list of 'data direct' MKEYs managed on the mlx5_ib device. 5) Return the crossing MKEY to the user, created with its supplied PD. Upon DMA PF unbind flow, the driver will revoke the KSM entries. The final deregistration will occur under the hood once the application deregisters its MKEY. Notes: - This version supports only the PINNED UMEM mode, so there is no dependency on ODP. - The IOVA supplied by the application must be system page aligned due to HW translations of KSM. - The crossing MKEY will not be umrable or part of the MR cache, as we cannot change its crossed (i.e. KSM) MKEY over UMR.

2024-08-10ALSA: pcm: Add xrun counter for snd_pcm_substreamNorman Bintang
This patch adds an xrun counter to snd_pcm_substream as an alternative to using logs from XRUN_DEBUG_BASIC. The counter provides a way to track the number of xrun occurences, accessible through the /proc interface. The counter is enabled when CONFIG_SND_PCM_XRUN_DEBUG is set. Example output: $ cat /proc/asound/card0/pcm9p/sub0/status owner_pid : 1425 trigger_time: 235.248957291 tstamp : 0.000000000 delay : 1912 avail : 480 avail_max : 1920 ----- hw_ptr : 672000 appl_ptr : 673440 xrun_counter: 3 # (new row) Signed-off-by: Norman Bintang <normanbt@chromium.org> Reviewed-by: Chih-Yang Hsia <paulhsia@chromium.org> Tested-by: Chih-Yang Hsia <paulhsia@chromium.org> Reviewed-by: David Riley <davidriley@chromium.org> Link: https://patch.msgid.link/20240809140648.3414349-1-normanbt@chromium.org Signed-off-by: Takashi Iwai <tiwai@suse.de>

2024-08-09irqdomain: Allow giving name suffix for domainMatti Vaittinen
Devices can provide multiple interrupt lines. One reason for this is that a device has multiple subfunctions, each providing its own interrupt line. Another reason is that a device can be designed to be used (also) on a system where some of the interrupts can be routed to another processor. A line often further acts as a demultiplex for specific interrupts and has it's respective set of interrupt (status, mask, ack, ...) registers. Regmap supports the handling of these registers and demultiplexing interrupts, but the interrupt domain code ends up assigning the same name for the per interrupt line domains. This causes a naming collision in the debugFS code and leads to confusion, as /proc/interrupts shows two separate interrupts with the same domain name and hardware interrupt number. Instead of adding a workaround in regmap or driver code, allow giving a name suffix for the domain name when the domain is created. Add a name_suffix field in the irq_domain_info structure and make irq_domain_instantiate() use this suffix if it is given when a domain is created.

2024-08-09irqdomain: Simplify simple and legacy domain creationMatti Vaittinen
irq_domain_create_simple() and irq_domain_create_legacy() use __irq_domain_instantiate(), but have extra handling of allocating interrupt descriptors and associating interrupts in them. Some of that is duplicated. There are also call sites which have conditonals to invoke different interrupt domain creator functions, where one of them is usually irq_domain_create_legacy(). Alternatively they associate the interrupts for the legacy case after creating the domain. Moving the extra logic of irq_domain_create_simple()/legacy() into __irq_domain_instantiate() allows to consolidate that. Introduce hwirq_base and virq_base members in the irq_domain_info structure, which allows to transport the required information and add the conditional interrupt descriptor allocation and interrupt association into __irq_domain_instantiate(). This reduces irq_domain_create_legacy() and irq_domain_create_simple() to trivial wrappers which fill in the info structure and allows call sites which must support the legacy case along with more modern mechanism to select the domain type via the parameters of the info struct.

2024-08-09PCI: Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()Philipp Stanner
pcim_iomap_regions() is a complicated function that uses a bit mask to determine the BARs the user wishes to request and ioremap. Almost all users only ever set a single bit in that mask, making that mechanism questionable. pcim_iomap_region() is now available as a more simple replacement. Make pcim_iomap_region() a public function. Mark pcim_iomap_regions() as deprecated.
