2024-01-04NFSv4.1/pnfs: Ensure we handle the error NFS4ERR_RETURNCONFLICTTrond Myklebust
Once the client has processed the CB_LAYOUTRECALL, but has not yet successfully returned the layout, the server is supposed to switch to returning NFS4ERR_RETURNCONFLICT. This patch ensures that we handle that return value correctly.

2024-01-04NFSv4.1: if referring calls are complete, trust the stateid argumentTrond Myklebust
If the server is recalling a layout, and sends us a list of referring calls that we can see are complete, then we should just trust that the stateid argument is correct, even if the sequence id doesn't match the one we hold.

2024-01-04NFSv4: Track the number of referring calls in struct cb_process_stateTrond Myklebust
When the server gives us a set of referring calls, to tell us that the NFSv4.1 callback needs to be ordered with respect to those calls, then we may want to make that information available to the operations. In certain cases, it may allow them to optimise their behaviour due to the extra knowledge.

2024-01-04NFS: Use parent's objective cred in nfs_access_login_time()Scott Mayhew
The subjective cred (task->cred) can potentially be overridden and subsquently freed in non-RCU context, which could lead to a panic if we try to use it in cred_fscmp(). Use __task_cred(), which returns the objective cred (task->real_cred) instead.

2024-01-04NFSv4: Always ask for type with READDIRBenjamin Coddington
Again we have claimed regressions for walking a directory tree, this time with the "find" utility which always tries to optimize away asking for any attributes until it has a complete list of entries. This behavior makes the readdir plus heuristic do the wrong thing, which causes a storm of GETATTRs to determine each entry's type in order to continue the walk. For v4 add the type attribute to each READDIR request to include it no matter the heuristic. This allows a simple `find` command to proceed quickly through a directory tree.

2024-01-04pnfs/blocklayout: Don't add zero-length pnfs_block_devBenjamin Coddington
We noticed a SCSI device that refused to allow READ CAPACITY when the device had a PR with exclusive access, registrants only. The result of this situation is that the blocklayout driver adds a pnfs_block_dev of zero length which always fails the offset_in_map tests. Instead of continuously trying to do pNFS for this case, just mark the device as unavailable which will allow the client to fallback to the MDS for the duration of PNFS_DEVICE_RETRY_TIMEOUT.

2024-01-04SUNRPC: Create a helper function for accessing the rpc_clnt's xprt_switchAnna Schumaker
This function takes the necessary rcu read lock to dereference the client's rpc_xprt_switch and bump the reference count so it doesn't disappear underneath us before returning.

2024-01-04KVM: x86/pmu: fix masking logic for MSR_CORE_PERF_GLOBAL_CTRLPaolo Bonzini
When commit c59a1f106f5c ("KVM: x86/pmu: Add IA32_PEBS_ENABLE MSR emulation for extended PEBS") switched the initialization of cpuc->guest_switch_msrs to use compound literals, it screwed up the boolean logic: + u64 pebs_mask = cpuc->pebs_enabled & x86_pmu.pebs_capable; ... - arr[0].guest = intel_ctrl & ~cpuc->intel_ctrl_host_mask; - arr[0].guest &= ~(cpuc->pebs_enabled & x86_pmu.pebs_capable); + .guest = intel_ctrl & (~cpuc->intel_ctrl_host_mask | ~pebs_mask), Before the patch, the value of arr[0].guest would have been intel_ctrl & ~cpuc->intel_ctrl_host_mask & ~pebs_mask. The intent is to always treat PEBS events as host-only because, while the guest runs, there is no way to tell the processor about the virtual address where to put PEBS records intended for the host. Unfortunately, the new expression can be expanded to (intel_ctrl & ~cpuc->intel_ctrl_host_mask) | (intel_ctrl & ~pebs_mask) which makes no sense; it includes any bit that isn't *both* marked as exclude_guest and using PEBS. So, reinstate the old logic. Another way to write it could be "intel_ctrl & ~(cpuc->intel_ctrl_host_mask | pebs_mask)", presumably the intention of the author of the faulty. However, I personally find the repeated application of A AND NOT B to be a bit more readable. This shows up as guest failures when running concurrent long-running perf workloads on the host, and was reported to happen with rcutorture. All guests on a given host would die simultaneously with something like an instruction fault or a segmentation violation. Reported-by: Paul E.

2024-01-04drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays ↵Joshua Ashton
without PSR The check for sending the vsc infopacket to the display was gated behind PSR (Panel Self Refresh) being enabled. The vsc infopacket also contains the colorimetry (specifically the container color gamut) information for the stream on modern DP. PSR is typically only supported on mobile phone eDP displays, thus this was not getting sent for typical desktop monitors or TV screens. This functionality is needed for proper HDR10 functionality on DP as it wants BT2020 RGB/YCbCr for the container color space.

2024-01-04net: mdio_bus: add refcounting for fwnodes to mdiobusRussell King (Oracle)
Luiz Angelo Daros de Luca reports that the MDIO bus code maintains a reference to the DT node, but does not hold a refcount on the node. The simple solution to this is to add the necessary refcounting into the MDIO bus code for all users, ensuring that on registration, the refcount is incremented, and only dropped when the MDIO bus is released. Do this for fwnodes, so we not only fix this for DT, but also other types of firmware nodes as well.

2024-01-04net: ravb: Wait for operating mode to be appliedClaudiu Beznea
CSR.OPS bits specify the current operating mode and (according to documentation) they are updated by HW when the operating mode change request is processed. To comply with this check CSR.OPS before proceeding. Commit introduces ravb_set_opmode() that does all the necessities for setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and wait for CSR.OPS) and call it where needed. This should comply with all the HW manuals requirements as different manual variants specify that different modes need to be checked in CSR.OPS when setting CCC.OPC. If gPTP active in config mode is supported and it needs to be enabled, the CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same write access. For this, ravb_set_opmode() allows passing GAC and CSEL as part of opmode and the function updates accordingly CCC register.
