2022-09-28Merge branch 'Parameterize task iterators.'Andrii Nakryiko11-46/+588
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/[email protected]/ v9: https://lore.kernel.org/bpf/[email protected]/ v8: https://lore.kernel.org/bpf/[email protected]/ v7: https://lore.kernel.org/bpf/[email protected]/ v6: https://lore.kernel.org/bpf/[email protected]/ v5: https://lore.kernel.org/bpf/[email protected]/ v4: https://lore.kernel.org/bpf/[email protected]/ v3: https://lore.kernel.org/bpf/[email protected]/ v2: https://lore.kernel.org/bpf/[email protected]/ v1: https://lore.kernel.org/bpf/[email protected]/ ==================== Signed-off-by: Andrii Nakryiko <[email protected]>
2022-09-28bpftool: Show parameters of BPF task iterators.Kui-Feng Lee1-0/+19
Show tid or pid of iterators if giving an argument of tid or pid For example, the command `bpftool link list` may list following lines. 1: iter prog 2 target_name bpf_map 2: iter prog 3 target_name bpf_prog 33: iter prog 225 target_name task_file tid 1644 pids test_progs(1644) Link 33 is a task_file iterator with tid 1644. For now, only targets of task, task_file and task_vma may be with tid or pid to filter out tasks other than those belonging to a process (pid) or a thread (tid).

2022-09-28bpf: Handle show_fdinfo for the parameterized task BPF iteratorsKui-Feng Lee1-0/+18
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.

2022-09-28ice: Add support for VLAN priority filters in switchdevMartyna Szapar-Mudlaw2-17/+60
Enable support for adding TC rules that filter on the VLAN priority in switchdev mode. VLAN priority are the first 3 bits of 16b switch field vector word which contain also vlan id value within its last 12 bits. When getting vlan priority value from tc match.key it has to be shifted first to proper bits positions (by VLAN_PRIO_SHIFT) and then can be added to the joint 'vlan' field in ice_vlan_hdr in lookup element. The mask of lookup changes accordingly. 0x0FFF - when only vlan id is added in filter 0xE000 - when only vlan priority is added in filter 0xEFFF - when both these values are specified Signed-off-by: Martyna Szapar-Mudlaw <[email protected]> Tested-by: Sujai Buvaneswaran <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>

2022-09-28ata: libata-sata: Fix device queue depth controlDamien Le Moal3-15/+16
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 Moal1-6/+4
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.
