git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Fix the style of protected key API driver source: use x-mas tree for all local variable declarations - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore. Both structures have a fixed size buffer, but with the support of ECC protected key these buffers are not big enough. Use dynamic buffers internally and transparently for userspace - Add support for a new 'non CCA clear key token' with ECC clear keys supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448. This makes it possible to derive a protected key from the ECC clear key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way to derive is via PCKMO instruction - The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t for reference counting. Replace this with the proper data type refcount_t - Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since gcc generates inefficient code, which may lead to stack overflows - Replace one-element array with flexible-array member in struct vfio_ccw_parent and refactor the rest of the code accordingly. Also, prefer struct_size() over sizeof() open- coded versions - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the system memory should be cleared or not once dumped - Fix a hang when a user attempts to remove a VFIO-AP mediated device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback to request a release of the device - Fix calculation for R_390_GOTENT relocations for modules - Allow any user space process with CAP_PERFMON capability read and display the CPU Measurement facility counter sets - Rework large statically-defined per-CPU cpu_cf_events data structure and replace it with dynamically allocated structures created when a perf_event_open() system call is invoked or /dev/hwctr device is accessed * tag 's390-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/cpum_cf: rework PER_CPU_DEFINE of struct cpu_cf_events s390/cpum_cf: open access to hwctr device for CAP_PERFMON privileged process s390/module: fix rela calculation for R_390_GOTENT s390/vfio-ap: wire in the vfio_device_ops request callback s390/vfio-ap: realize the VFIO_DEVICE_SET_IRQS ioctl s390/vfio-ap: realize the VFIO_DEVICE_GET_IRQ_INFO ioctl s390/pkey: add support for ecc clear key s390/pkey: do not use struct pkey_protkey s390/pkey: introduce reverse x-mas trees s390/zcore: conditionally clear memory on reipl s390/ipl: add REIPL_CLEAR flag to os_info vfio/ccw: use struct_size() helper vfio/ccw: replace one-element array with flexible-array member s390: select ARCH_SUPPORTS_INT128 s390/pai_ext: replace atomic_t with refcount_t s390/pai_crypto: replace atomic_t with refcount_t

Instead of a 6-parameter horror that forced u128 - u64/u64-halves layout details on the interface and exposed users to complexity, fragility & bugs, use a natural 3-parameter interface with u128 types. - Restructure the generated atomic headers, and add kerneldoc comments for all of the generic atomic{,64,_long}_t operations. The generated definitions are much cleaner now, and come with documentation. - Implement lock_set_cmp_fn() on lockdep, for defining an ordering when taking multiple locks of the same type.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: "Scheduler SMP load-balancer improvements: - Avoid unnecessary migrations within SMT domains on hybrid systems. Problem: On hybrid CPU systems, (processors with a mixture of higher-frequency SMT cores and lower-frequency non-SMT cores), under the old code lower-priority CPUs pulled tasks from the higher-priority cores if more than one SMT sibling was busy - resulting in many unnecessary task migrations. Solution: The new code improves the load balancer to recognize SMT cores with more than one busy sibling and allows lower-priority CPUs to pull tasks, which avoids superfluous migrations and lets lower-priority cores inspect all SMT siblings for the busiest queue. - Implement the 'runnable boosting' feature in the EAS balancer: consider CPU contention in frequency, EAS max util & load-balance busiest CPU selection. This improves CPU utilization for certain workloads, while leaves other key workloads unchanged. Scheduler infrastructure improvements: - Rewrite the scheduler topology setup code by consolidating it into the build_sched_topology() helper function and building it dynamically on the fly. - Resolve the local_clock() vs. noinstr complications by rewriting the code: provide separate sched_clock_noinstr() and local_clock_noinstr() functions to be used in instrumentation code, and make sure it is all instrumentation-safe.

2023-06-27net: scm: introduce and use scm_recv_unix helperAlexander Mikhalitsyn2-12/+27
Recently, our friends from bluetooth subsystem reported [1] that after commit 5e2ff6704a27 ("scm: add SO_PASSPIDFD and SCM_PIDFD") scm_recv() helper become unusable in kernel modules (because it uses unexported pidfd_prepare() API). We were aware of this issue and workarounded it in a hard way by commit 97154bcf4d1b ("af_unix: Kconfig: make CONFIG_UNIX bool"). But recently a new functionality was added in the scope of commit 817efd3cad74 ("Bluetooth: hci_sock: Forward credentials to monitor") and after that bluetooth can't be compiled as a kernel module. After some discussion in [1] we decided to split scm_recv() into two helpers, one won't support SCM_PIDFD (used for unix sockets), and another one will be completely the same as it was before commit 5e2ff6704a27 ("scm: add SO_PASSPIDFD and SCM_PIDFD").

2023-06-27af_unix: Skip SCM_PIDFD if scm->pid is NULL.Kuniyuki Iwashima1-1/+3
syzkaller hit a WARN_ON_ONCE(!scm->pid) in scm_pidfd_recv(). In unix_stream_read_generic(), if there is no skb in the queue, we could bail out the do-while loop without calling scm_set_cred(): 1. No skb in the queue 2. sk is non-blocking or shutdown(sk, RCV_SHUTDOWN) is called concurrently or peer calls close() If the socket is configured with SO_PASSPIDFD, scm_pidfd_recv() would populate cmsg with garbage emitting the warning. Let's skip SCM_PIDFD if scm->pid is NULL in scm_pidfd_recv(). Note another way would be skip calling scm_recv() in such cases, but this caused a regression resulting in commit 9d797ee2dce1 ("Revert "af_unix: Call scm_recv() only after scm_set_cred()."").

2023-06-27netlink: Add __sock_i_ino() for __netlink_diag_dump().Kuniyuki Iwashima3-4/+16
syzbot reported a warning in __local_bh_enable_ip(). [0] Commit 8d61f926d420 ("netlink: fix potential deadlock in netlink_set_err()") converted read_lock(&nl_table_lock) to read_lock_irqsave() in __netlink_diag_dump() to prevent a deadlock. However, __netlink_diag_dump() calls sock_i_ino() that uses read_lock_bh() and read_unlock_bh(). If CONFIG_TRACE_IRQFLAGS=y, read_unlock_bh() finally enables IRQ even though it should stay disabled until the following read_unlock_irqrestore(). Using read_lock() in sock_i_ino() would trigger a lockdep splat in another place that was fixed in commit f064af1e500a ("net: fix a lockdep splat"), so let's add __sock_i_ino() that would be safe to use under BH disabled.

2023-06-27net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC addressesVladimir Oltean5-31/+74
When using the felix driver (the only one which supports UC filtering and MC filtering) as a DSA master for a random other DSA switch, one can see the following stack trace when the downstream switch ports join a VLAN-aware bridge: ============================= WARNING: suspicious RCU usage ----------------------------- net/8021q/vlan_core.c:238 suspicious rcu_dereference_protected() usage! stack backtrace: Workqueue: dsa_ordered dsa_slave_switchdev_event_work Call trace: lockdep_rcu_suspicious+0x170/0x210 vlan_for_each+0x8c/0x188 dsa_slave_sync_uc+0x128/0x178 __hw_addr_sync_dev+0x138/0x158 dsa_slave_set_rx_mode+0x58/0x70 __dev_set_rx_mode+0x88/0xa8 dev_uc_add+0x74/0xa0 dsa_port_bridge_host_fdb_add+0xec/0x180 dsa_slave_switchdev_event_work+0x7c/0x1c8 process_one_work+0x290/0x568 What it's saying is that vlan_for_each() expects rtnl_lock() context and it's not getting it, when it's called from the DSA master's ndo_set_rx_mode(). The caller of that - dsa_slave_set_rx_mode() - is the slave DSA interface's dsa_port_bridge_host_fdb_add() which comes from the deferred dsa_slave_switchdev_event_work(). We went to great lengths to avoid the rtnl_lock() context in that call path in commit 0faf890fc519 ("net: dsa: drop rtnl_lock from dsa_slave_switchdev_event_work"), and calling rtnl_lock() is simply not an option due to the possibility of deadlocking when calling dsa_flush_workqueue() from the call paths that do hold rtnl_lock() - basically all of them. So, when the DSA master calls vlan_for_each() from its ndo_set_rx_mode(), the state of the 8021q driver on this device is really not protected from concurrent access by anything. Looking at net/8021q/, I don't think that vlan_info->vid_list was particularly designed with RCU traversal in mind, so introducing an RCU read-side form of vlan_for_each() - vlan_for_each_rcu() - won't be so easy, and it also wouldn't be exactly what we need anyway. In general I believe that the solution isn't in net/8021q/ anyway; vlan_for_each() is not cut out for this task. DSA doesn't need rtnl_lock() to be held per se - since it's not a netdev state change that we're blocking, but rather, just concurrent additions/removals to a VLAN list. We don't even need sleepable context - the callback of vlan_for_each() just schedules deferred work. The proposed escape is to remove the dependency on vlan_for_each() and to open-code a non-sleepable, rtnl-free alternative to that, based on copies of the VLAN list modified from .ndo_vlan_rx_add_vid() and .ndo_vlan_rx_kill_vid().

2023-06-27libceph: Partially revert changes to support MSG_SPLICE_PAGESDavid Howells2-39/+107
Fix the mishandling of MSG_DONTWAIT and also reinstates the per-page checking of the source pages (which might have come from a DIO write by userspace) by partially reverting the changes to support MSG_SPLICE_PAGES and doing things a little differently. In messenger_v1: (1) The ceph_tcp_sendpage() is resurrected and the callers reverted to use that. (2) The callers now pass MSG_MORE unconditionally. Previously, they were passing in MSG_MORE|MSG_SENDPAGE_NOTLAST and then degrading that to just MSG_MORE on the last call to ->sendpage(). (3) Make ceph_tcp_sendpage() a wrapper around sendmsg() rather than sendpage(), setting MSG_SPLICE_PAGES if sendpage_ok() returns true on the page. In messenger_v2: (4) Bring back do_try_sendpage() and make the callers use that. (5) Make do_try_sendpage() use sendmsg() for both cases and set MSG_SPLICE_PAGES if sendpage_ok() is set.
