2025-02-03accel/ivpu: Enable recovery and adjust timeouts for fpgaTomasz Rusinowicz
Recovery now works on fpga. JSM state dump timeout needs to be really long for the new fpga model releases. Enable punit on fpga.

Move the ivpu_mmu_discard_events() function to the common portion of the abort work function. This ensures it is called only once, even if there are no faulty contexts in context_xa, to guarantee that MMU events are discarded and new events are not missed.

2025-02-03accel/ivpu: Add support for hardware fault injectionJacek Lawrynowicz
Introduces the capability to simulate hardware faults for testing purposes. The new `fail_hw` fault can be injected in `ivpu_hw_reg_poll_fld()`, which is used in various parts of the driver to wait for the hardware to reach a specific state. This allows to test failures during NPU boot and shutdown, IPC message handling and more. Fault injection can be enabled using debugfs or a module parameter.

2025-02-03arm64: dts: rockchip: Disable DMA for uart5 on px30-ringneckLukasz Czechowski
UART controllers without flow control seem to behave unstable in case DMA is enabled. The issues were indicated in the message: https://lore.kernel.org/linux-arm-kernel/CAMdYzYpXtMocCtCpZLU_xuWmOp2Ja_v0Aj0e6YFNRA-yV7u14g@mail.gmail.com/ In case of PX30-uQ7 Ringneck SoM, it was noticed that after couple of hours of UART communication, the CPU stall was occurring, leading to the system becoming unresponsive. After disabling the DMA, extensive UART communication tests for up to two weeks were performed, and no issues were further observed. The flow control pins for uart5 are not available on PX30-uQ7 Ringneck, as configured by pinctrl-0, so the DMA nodes were removed on SoM dtsi.

Commit c8c68c38b56f ("cpufreq: amd-pstate: initialize core precision boost state") sets per-policy boost flag to false when boost fail. However, this boost flag will be set to reverse value in store_local_boost() and cpufreq_boost_trigger_state() in cpufreq.c. This will cause the per-policy boost flag set to true when fail to set boost.

2025-02-02cgroup: fix race between fork and cgroup.killShakeel Butt
Tejun reported the following race between fork() and cgroup.kill at [1]. Tejun: I was looking at cgroup.kill implementation and wondering whether there could be a race window. So, __cgroup_kill() does the following: k1. Set CGRP_KILL. k2. Iterate tasks and deliver SIGKILL. k3. Clear CGRP_KILL. The copy_process() does the following: c1. Copy a bunch of stuff. c2. Grab siglock. c3. Check fatal_signal_pending(). c4. Commit to forking. c5. Release siglock. c6. Call cgroup_post_fork() which puts the task on the css_set and tests CGRP_KILL. The intention seems to be that either a forking task gets SIGKILL and terminates on c3 or it sees CGRP_KILL on c6 and kills the child. However, I don't see what guarantees that k3 can't happen before c6. ie. After a forking task passes c5, k2 can take place and then before the forking task reaches c6, k3 can happen. Then, nobody would send SIGKILL to the child. What am I missing? This is indeed a race. One way to fix this race is by taking cgroup_threadgroup_rwsem in write mode in __cgroup_kill() as the fork() side takes cgroup_threadgroup_rwsem in read mode from cgroup_can_fork() to cgroup_post_fork(). However that would be heavy handed as this adds one more potential stall scenario for cgroup.kill which is usually called under extreme situation like memory pressure. To fix this race, let's maintain a sequence number per cgroup which gets incremented on __cgroup_kill() call. On the fork() side, the cgroup_can_fork() will cache the sequence number locally and recheck it against the cgroup's sequence number at cgroup_post_fork() site. If the sequence numbers mismatch, it means __cgroup_kill() can been called and we should send SIGKILL to the newly created task.

nfsd_file_dispose_list_delayed can be called from the filecache laundrette, which is shut down after the nfsd threads are shut down and the nfsd_serv pointer is cleared. If nn->nfsd_serv is NULL then there are no threads to wake. Ensure that the nn->nfsd_serv pointer is non-NULL before calling svc_wake_up in nfsd_file_dispose_list_delayed. This is safe since the svc_serv is not freed until after the filecache laundrette is cancelled.

2025-02-01vmxnet3: Fix tx queue race condition with XDPSankararaman Jayaraman
If XDP traffic runs on a CPU which is greater than or equal to the number of the Tx queues of the NIC, then vmxnet3_xdp_get_tq() always picks up queue 0 for transmission as it uses reciprocal scale instead of simple modulo operation. vmxnet3_xdp_xmit() and vmxnet3_xdp_xmit_frame() use the above returned queue without any locking which can lead to race conditions when multiple XDP xmits run in parallel on different CPU's. This patch uses a simple module scheme when the current CPU equals or exceeds the number of Tx queues on the NIC. It also adds locking in vmxnet3_xdp_xmit() and vmxnet3_xdp_xmit_frame() functions.

2025-02-01mm/hugetlb: fix hugepage allocation for interleaved memory nodesRitesh Harjani (IBM)
gather_bootmem_prealloc() assumes the start nid as 0 and size as num_node_state(N_MEMORY). That means in case if memory attached numa nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail to scan few of these nodes. Since memory attached numa nodes can be interleaved in any fashion, hence ensure that the current code checks for all numa node ids (.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that it can distributes all nr_node_ids among the these many no. threads. e.g. qemu cmdline ======================== numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20" mem_cmd="-object memory-backend-ram,id=mem1,size=16G" w/o this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): ========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 0 kB with this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): =========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 2 HugePages_Free: 2 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 2097152 kB Link: https://lkml.kernel.org/r/f8d8dad3a5471d284f54185f65d575a6aaab692b.1736592534.git.ritesh.list@gmail.com Fixes: b78b27d02930 ("hugetlb: parallelize 1G hugetlb initialization") Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reported-by: Pavithra Prakash <pavrampu@linux.ibm.com> Suggested-by: Muchun Song <muchun.song@linux.dev> Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> Reviewed-by: Luiz Capitulino <luizcap@redhat.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Donet Tom <donettom@linux.ibm.com> Cc: Gang Li <gang.li@linux.dev> Cc: Daniel Jordan <daniel.m.jordan@oracle.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

We can run into an infinite loop in __get_longterm_locked() when collect_longterm_unpinnable_folios() finds only folios that are isolated from the LRU or were never added to the LRU. This can happen when all folios to be pinned are never added to the LRU, for example when vm_ops->fault allocated pages using cma_alloc() and never added them to the LRU. Fix it by simply taking a look at the list in the single caller, to see if anything was added.
