2022-09-28io_uring/poll: disable level triggered pollJens Axboe
Stefan reports that there are issues with the level triggered notification. Since we're late in the cycle, and it was introduced for the 6.0 release, just disable it at prep time and we can bring this back when Samba is happy with it.

2022-09-28clk: sunxi-ng: h6: Fix default PLL GPU rateJernej Skrabec
In commit 4167ac8a657e ("clk: sunxi-ng: sun50i: h6: Modify GPU clock configuration to support DFS") divider M0 was forced to be 1 in order to support DFS. However, that left N as it is, at high value of 36. On boards without devfreq enabled (all of them in kernel 6.0), this effectively sets GPU frequency to 864 MHz. This is about 100 MHz above maximum supported frequency. In order to fix this, let's set N to 18 (register value 17). That way default frequency of 432 MHz is preserved.

2022-09-28Merge branch 'Parameterize task iterators.'Andrii Nakryiko
Kui-Feng Lee says: ==================== Allow creating an iterator that loops through resources of one task/thread. People could only create iterators to loop through all resources of files, vma, and tasks in the system, even though they were interested in only the resources of a specific task or process. Passing the additional parameters, people can now create an iterator to go through all resources or only the resources of a task. Major Changes: - Add new parameters in bpf_iter_link_info to indicate to go through all tasks or to go through a specific task. - Change the implementations of BPF iterators of vma, files, and tasks to allow going through only the resources of a specific task. - Provide the arguments of parameterized task iterators in bpf_link_info. Differences from v10: - Check pid_alive() to avoid potential errors. Differences from v9: - Fix the boundary check of computing page_shift. - Rewording the reason of checking and returning the same task. Differences from v8: - Fix uninitialized variable. - Avoid redundant work of getting task from pid. - Change format string to use %u instead of %d. - Use the value of page_shift to compute correct offset in bpf_iter_vm_offset.c. Differences from v7: - Travel the tasks of a process through task_group linked list instead of traveling through the whole namespace. Differences from v6: - Add part 5 to make bpftool show the value of parameters. - Change of wording of show_fdinfo() to show pid or tid instead of always pid. - Simplify error handling and naming of test cases. Differences from v5: - Use user-space tid/pid terminologies in bpf_iter_link_info and bpf_link_info. - Fix reference count - Merge all variants to one 'u32 pid' in internal structs. (bpf_iter_aux_info and bpf_iter_seq_task_common) - Compare the result of get_uprobe_offset() with the implementation with the vma iterators. - Implement show_fdinfo. Differences from v4: - Remove 'type' from bpf_iter_link_info and bpf_link_info. v10: https://lore.kernel.org/all/20220831181039.2680134-1-kuifeng@fb.com/ v9: https://lore.kernel.org/bpf/20220829192317.486946-1-kuifeng@fb.com/ v8: https://lore.kernel.org/bpf/20220829192317.486946-1-kuifeng@fb.com/ v7: https://lore.kernel.org/bpf/20220826003712.2810158-1-kuifeng@fb.com/ v6: https://lore.kernel.org/bpf/20220819220927.3409575-1-kuifeng@fb.com/ v5: https://lore.kernel.org/bpf/20220811001654.1316689-1-kuifeng@fb.com/ v4: https://lore.kernel.org/bpf/20220809195429.1043220-1-kuifeng@fb.com/ v3: https://lore.kernel.org/bpf/20220809063501.667610-1-kuifeng@fb.com/ v2: https://lore.kernel.org/bpf/20220801232649.2306614-1-kuifeng@fb.com/ v1: https://lore.kernel.org/bpf/20220726051713.840431-1-kuifeng@fb.com/ ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>

2022-09-28bpf: Handle show_fdinfo for the parameterized task BPF iteratorsKui-Feng Lee
Show information of iterators in the respective files under /proc/<pid>/fdinfo/. For example, for a task file iterator with 1723 as the value of tid parameter, its fdinfo would look like the following lines. pos: 0 flags: 02000000 mnt_id: 14 ino: 38 link_type: iter link_id: 51 prog_tag: a590ac96db22b825 prog_id: 299 target_name: task_file task_type: TID tid: 1723 This patch add the last three fields. task_type is the type of the task parameter. TID means the iterator visit only the thread specified by tid. The value of tid in the above example is 1723. For the case of PID task_type, it means the iterator visits only threads of a process and will show the pid value of the process instead of a tid.

This is useful on !virt platforms for kexec, so change things from BI_VIRT_RNG_SEED to be BI_RNG_SEED, and simply remove BI_VIRT_RNG_SEED because it only ever lasted one release, and nothing is broken by not having it.

2022-09-28x86/cacheinfo: Add a cpu_llc_shared_mask() UP variantBorislav Petkov
On a CONFIG_SMP=n kernel, the LLC shared mask is 0, which prevents __cache_amd_cpumap_setup() from doing the L3 masks setup, and more specifically from setting up the shared_cpu_map and shared_cpu_list files in sysfs, leading to lscpu from util-linux getting confused and segfaulting. Add a cpu_llc_shared_mask() UP variant which returns a mask with a single bit set, i.e., for CPU0.

2022-09-28Revert "net: set proper memcg for net_init hooks allocations"Shakeel Butt
This reverts commit 1d0403d20f6c281cb3d14c5f1db5317caeec48e9. Anatoly Pugachev reported that the commit 1d0403d20f6c ("net: set proper memcg for net_init hooks allocations") is somehow causing the sparc64 VMs failed to boot and the VMs boot fine with that patch reverted. So, revert the patch for now and later we can debug the issue.

When synthesizing event with SPE data source, commit 4e6430cbb1a9("perf arm-spe: Use SPE data source for neoverse cores") augment the type with source information by MIDR. However, is_midr_in_range only compares the first entry in neoverse_spe. Change is_midr_in_range to is_midr_in_range_list to traverse the neoverse_spe array so that all neoverse cores synthesize event with data source packet.

2022-09-28perf tests vmlinux-kallsyms: Update is_ignored_symbol function to match the ↵Athira Rajeev
kernel ignored list The testcase “vmlinux-kallsyms.c” fails in powerpc. vmlinux symtab matches kallsyms: FAILED! This test look at the symbols in the vmlinux DSO and check if we find all of them in the kallsyms dso. But from the powerpc logs , observed that the failure happens for: ERR : 0xc0000000000fe9c8: .Lmfspr_table not on kallsyms ERR : 0xc0000000001009c8: .Lmtspr_table not on kallsyms These are labels ( with .L) in the source code and has to be ignored. Reference code with .Lmtspr_table: arch/powerpc/xmon/spr_access.S The testcases invokes is_ignored_symbol() function to ignore hidden symbols in the dso like local symbols. This function is adapted from is_ignored_symbol() kernel function in code: scripts/kallsyms.c . The kernel function got some updates which is not reflected in the testcase function and the new updates also handles ignoring "labels". Below is the changes that went in the kernel function. /* Symbol names that begin with the following are ignored.*/ static const char * const ignored_prefixes[] = { "$", /* local symbols for ARM, MIPS, etc. */ - ".LASANPC", /* s390 kasan local symbols */ + ".L", /* local labels, .LBB,.Ltmpxxx,.L__unnamed_xx,.LASANPC, etc. */ "__crc_", /* modversions */ "__efistub_", /* arm64 EFI stub namespace */ - "__kvm_nvhe_", /* arm64 non-VHE KVM namespace */ + "__kvm_nvhe_$", /* arm64 local symbols in non-VHE KVM namespace */ + "__kvm_nvhe_.L", /* arm64 local symbols in non-VHE KVM namespace */ "__AArch64ADRPThunk_", /* arm64 lld */ "__ARMV5PILongThunk_", /* arm lld */ "__ARMV7PILongThunk_", This change is part of below commits and will handle the symbols with “.L” commit d4c858643263 ("kallsyms: ignore all local labels prefixed by '.L'") commit 6ccf9cb557bd ("KVM: arm64: Symbolize the nVHE HYP addresses") Update the testcase function to include the new changes.

2022-09-28ata: libata-sata: Fix device queue depth controlDamien Le Moal
The function __ata_change_queue_depth() uses the helper ata_scsi_find_dev() to get the ata_device structure of a scsi device and set that device maximum queue depth. However, when the ata device is managed by libsas, ata_scsi_find_dev() returns NULL, turning __ata_change_queue_depth() into a nop, which prevents the user from setting the maximum queue depth of ATA devices used with libsas based HBAs. Fix this by renaming __ata_change_queue_depth() to ata_change_queue_depth() and adding a pointer to the ata_device structure of the target device as argument. This pointer is provided by ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of a libata managed device and by sas_change_queue_depth() using sas_to_ata_dev() in the case of a libsas managed ata device.

2022-09-28ata: libata-scsi: Fix initialization of device queue depthDamien Le Moal
For SATA devices supporting NCQ, drivers using libsas first initialize a scsi device queue depth based on the controller and device capabilities, leading to the scsi device queue_depth field being 32 (ATA maximum queue depth) for most setup. However, if libata was loaded using the force=[ID]]noncq argument, the default queue depth should be set to 1 to reflect the fact that queuable commands will never be used. This is consistent with manually setting a device queue depth to 1 through sysfs as that disables NCQ use for the device. Fix ata_scsi_dev_config() to honor the noncq parameter by sertting the device queue depth to 1 for devices that do not have the ATA_DFLAG_NCQ flag set.
