2023-08-01net/sched: wrap open coded Qdics class filter counterPedro Tammela
The 'filter_cnt' counter is used to control a Qdisc class lifetime. Each filter referecing this class by its id will eventually increment/decrement this counter in their respective 'add/update/delete' routines. As these operations are always serialized under rtnl lock, we don't need an atomic type like 'refcount_t'. It also means that we lose the overflow/underflow checks already present in refcount_t, which are valuable to hunt down bugs where the unsigned counter wraps around as it aids automated tools like syzkaller to scream in such situations. Wrap the open coded increment/decrement into helper functions and add overflow checks to the operations.

2023-08-01serial: core: Fix serial core port id to not use port->lineTony Lindgren
The serial core port id should be serial core controller specific port instance, which is not always the port->line index. For example, 8250 driver maps a number of legacy ports, and when a hardware specific device driver takes over, we typically have one driver instance for each port. Let's instead add port->port_id to keep track serial ports mapped to each serial core controller instance. Currently this is only a cosmetic issue for the serial core port device names. The issue can be noticed looking at /sys/bus/serial-base/devices for example though. Let's fix the issue to avoid port addressing issues later on.

The switch component was never completed and sat half empty for over 3 years. It was recently deleted. For modern components this would require not change in the kernel but since this was a legacy allocation from the enum days of IPC3 we should mark the respective enum as deprecated.

2023-07-31tcx: Fix splat during dev unregisterMartin KaFai Lau
During unregister_netdevice_many_notify(), the ordering of our concerned function calls is like this: unregister_netdevice_many_notify dev_shutdown qdisc_put clsact_destroy tcx_uninstall The syzbot reproducer triggered a case that the qdisc refcnt is not zero during dev_shutdown(). tcx_uninstall() will then WARN_ON_ONCE(tcx_entry(entry)->miniq_active) because the miniq is still active and the entry should not be freed. The latter assumed that qdisc destruction happens before tcx teardown. This fix is to avoid tcx_uninstall() doing tcx_entry_free() when the miniq is still alive and let the clsact_destroy() do the free later, so that we do not assume any specific ordering for either of them. If still active, tcx_uninstall() does clear the entry when flushing out the prog/link. clsact_destroy() will then notice the "!tcx_entry_is_active()" and then does the tcx_entry_free() eventually.

2023-07-31eventfs: Move tracing/events to eventfsAjay Kaher
Up until now, /sys/kernel/tracing/events was no different than any other part of tracefs. The files and directories within the events directory was created when the tracefs was mounted, and also created for the instances in /sys/kernel/tracing/instances/<instance>/events. Most of these files and directories will never be referenced. Since there are thousands of these files and directories they spend their time wasting precious memory resources. Move the "events" directory to the new eventfs. The eventfs will take the meta data of the events that they represent and store that. When the files in the events directory are referenced, the dentry and inodes to represent them are then created. When the files are no longer referenced, they are freed. This saves the precious memory resources that were wasted on these seldom referenced dentries and inodes. Running the following: ~# cat /proc/meminfo /proc/slabinfo > before.out ~# mkdir /sys/kernel/tracing/instances/foo ~# cat /proc/meminfo /proc/slabinfo > after.out to test the changes produces the following deltas: Before this change: Before after deltas for meminfo: MemFree: -32260 MemAvailable: -21496 KReclaimable: 21528 Slab: 22440 SReclaimable: 21528 SUnreclaim: 912 VmallocUsed: 16 Before after deltas for slabinfo: <slab>: <objects> [ * <size> = <total>] tracefs_inode_cache: 14472 [* 1184 = 17134848] buffer_head: 24 [* 168 = 4032] hmem_inode_cache: 28 [* 1480 = 41440] dentry: 14450 [* 312 = 4508400] lsm_inode_cache: 14453 [* 32 = 462496] vma_lock: 11 [* 152 = 1672] vm_area_struct: 2 [* 184 = 368] trace_event_file: 1748 [* 88 = 153824] kmalloc-256: 1072 [* 256 = 274432] kmalloc-64: 2842 [* 64 = 181888] Total slab additions in size: 22,763,400 bytes With this change: Before after deltas for meminfo: MemFree: -12600 MemAvailable: -12580 Cached: 24 Active: 12 Inactive: 68 Inactive(anon): 48 Active(file): 12 Inactive(file): 20 Dirty: -4 AnonPages: 68 KReclaimable: 12 Slab: 1856 SReclaimable: 12 SUnreclaim: 1844 KernelStack: 16 PageTables: 36 VmallocUsed: 16 Before after deltas for slabinfo: <slab>: <objects> [ * <size> = <total>] tracefs_inode_cache: 108 [* 1184 = 127872] buffer_head: 24 [* 168 = 4032] hmem_inode_cache: 18 [* 1480 = 26640] dentry: 127 [* 312 = 39624] lsm_inode_cache: 152 [* 32 = 4864] vma_lock: 67 [* 152 = 10184] vm_area_struct: -12 [* 184 = -2208] trace_event_file: 1764 [* 96 = 169344] kmalloc-96: 14322 [* 96 = 1374912] kmalloc-64: 2814 [* 64 = 180096] kmalloc-32: 1103 [* 32 = 35296] kmalloc-16: 2308 [* 16 = 36928] kmalloc-8: 12800 [* 8 = 102400] Total slab additions in size: 2,109,984 bytes Which is a savings of 20,653,416 bytes (20 MB) per tracing instance.

As we gain more tests, boilerplate to allocate an atomic state and free it starts to be there more and more as well. In order to reduce the allocation boilerplate, we can create a helper to create that atomic state, and call an action when the test is done. This will also clean up the exit path.

2023-07-31drm/tests: helpers: Create a helper to allocate a locking ctxMaxime Ripard
As we get more and more tests, the locking context initialisation creates more and more boilerplate, both at creation and destruction. Let's create a helper that will allocate, initialise a context, and register kunit actions to clean up once the test is done.

2023-07-30eventfs: Implement removal of meta data from eventfsAjay Kaher
When events are removed from tracefs, the eventfs must be aware of this. The eventfs_remove() removes the meta data from eventfs so that it will no longer create the files associated with that event. When an instance is removed from tracefs, eventfs_remove_events_dir() will remove and clean up the entire "events" directory. The helper function eventfs_remove_rec() is used to clean up and free the associated data from eventfs for both of the added functions. SRCU is used to protect the lists of meta data stored in the eventfs. The eventfs_mutex is used to protect the content of the items in the list. As lookups may be happening as deletions of events are made, the freeing of dentry/inodes and relative information is done after the SRCU grace period has passed.

2023-07-30RDMA/irdma: Allow accurate reporting on QP max send/recv WRSindhu Devale
Currently the attribute cap.max_send_wr and cap.max_recv_wr sent from user-space during create QP are the provider computed SQ/RQ depth as opposed to raw values passed from application. This inhibits computation of an accurate value for max_send_wr and max_recv_wr for this QP in the kernel which matches the value returned in user create QP. Also these capabilities needs to be reported from the driver in query QP. Add support by extending the ABI to allow the raw cap.max_send_wr and cap.max_recv_wr to be passed from user-space, while keeping compatibility for the older scheme. The internal HW depth and shift needed for the WQs needs to be computed now for both kernel and user-mode QPs. Add new helpers to assist with this: irdma_uk_calc_depth_shift_sq, irdma_uk_calc_depth_shift_rq and irdma_uk_calc_depth_shift_wq. Consolidate all the user mode QP setup into a new function irdma_setup_umode_qp which keeps it with its counterpart irdma_setup_kmode_qp.
