2023-08-22parisc: Use generic mmap top-down layout and brk randomizationHelge Deller
parisc uses a top-down layout by default that exactly fits the generic functions, so get rid of arch specific code and use the generic version by selecting ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT. Note that on parisc the stack always grows up and a "unlimited stack" simply means that the value as defined in CONFIG_STACK_MAX_DEFAULT_SIZE_MB should be used. So RLIM_INFINITY is not an indicator to use the legacy memory layout. Signed-off-by: Helge Deller <deller@gmx.de>
2023-08-22parisc: Fix /proc/cpuinfo output for lscpuHelge Deller
The lscpu command is broken since commit cab56b51ec0e ("parisc: Fix device names in /proc/iomem") added the PA pathname to all PA devices, includig the CPUs. lscpu parses /proc/cpuinfo and now believes it found different CPU types since every CPU is listed with an unique identifier (PA pathname). Fix this problem by simply dropping the PA pathname when listing the CPUs in /proc/cpuinfo. There is no need to show the pathname in this procfs file.

An XS_WATCH write to the xenbus file then results in a complain about the opposite lock order &u->msgbuffer_mutex --> xs_watch_rwsem. The dependency xs_watch_rwsem --> xs_response_mutex is spurious. Avoid it and the warning by changing the ordering in xs_suspend(), first acquire xs_response_mutex and then xs_watch_rwsem. Reverse also the unlocking order in xs_suspend_cancel() for consistency, but keep xs_resume() as is because it needs to have xs_watch_rwsem unlocked only after exiting xs suspend and re-adding all watches.

2023-08-21selftests: bonding: do not set port down before adding to bondHangbin Liu
Before adding a port to bond, it need to be set down first. In the lacpdu test the author set the port down specifically. But commit a4abfa627c38 ("net: rtnetlink: Enslave device before bringing it up") changed the operation order, the kernel will set the port down _after_ adding to bond. So all the ports will be down at last and the test failed. In fact, the veth interfaces are already inactive when added. This means there's no need to set them down again before adding to the bond. Let's just remove the link down operation.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.6 Compatible and clock handling in the Qualcomm SCM driver is cleaned up, together with a couple stylistic cleanups and transition to mark exported symbols GPL only. An abstraction for the RPM subsystem is introduced, to make align the structure of the SMD and GLINK nodes thereof with the structure when a remoteproc is involved. This is done to facilitate associating additional entities with the RPM subsystem. The qmp_send() API is modified to not expose hardware requirements onto the client drivers, and then further extended to allow command formatting directly in the API, to facilitate this typical use case. In the Qualcomm Command DB driver, NUL characters previously included in identifiers are dropped from the debugfs, to facilitate scripting. The thresholds of the BWMON driver are simplified to avoid hard coded starting values. The OCMEM driver is updated with some cleanups and fixes, and addition of MSM8226 support. PMIC_GLINK gains support for retimer switches, safe mode is selected when the cable is disconnected from altmode and the same is enabled for SM8550. An off-by-one string length check is corrected in the QMI encoder decoder library. The RPMh tracepoints are extended to include the state of the request, to provide needed context in the traced events. The series from Ulf creating a genpd framework is integrated, to facilitate the other changes to the cpr, rpmpd and rpmhpd driver. SDX75 support is added to the rpmhpd driver, and the rpmpd driver is extended with the same sync_state logic found in the rpmhpd driver. The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019 platform is dropped. Clock handling in the GSBI driver is cleaned up with the use of devm_clk_get_enabled(). The list of VMIDs defined for the SCM assign memory interface is extended. * tag 'qcom-drivers-for-6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (52 commits) soc: qcom: aoss: Tidy up qmp_send() callers soc: qcom: aoss: Format string in qmp_send() soc: qcom: aoss: Move length requirements from caller dt-bindings: firmware: qcom: scm: Updating VMID list dt-bindings: qcom: Update RPMHPD entries for some SoCs soc: qcom: qmi_encdec: Restrict string length in decode soc: qcom: smem: Fix incompatible types in comparison soc: qcom: ocmem: add missing clk_disable_unprepare() in ocmem_dev_probe() soc: qcom: socinfo: Add SoC ID for SM7125 dt-bindings: arm: qcom,ids: Add SoC ID for SM7125 dt-bindings: arm: qcom,ids: drop the IPQ5019 SoC ID soc: qcom: socinfo: drop the IPQ5019 SoC ID soc: qcom: socinfo: add SM4450 ID dt-bindings: arm: qcom,ids: add SoC ID for SM4450 soc: qcom: pmic_glink: enable altmode for SM8550 soc: qcom: pmic_glink_altmode: add retimer-switch support soc: qcom: pmic_glink_altmode: handle safe mode when disconnect soc: qcom: rpmhpd: Add SDX75 power domains dt-bindings: power: qcom,rpmpd: Add compatible for sdx75 genpd: Makefile: build imx ...

Jiri Olsa says: ==================== bpf: Add multi uprobe link hi, this patchset is adding support to attach multiple uprobes and usdt probes through new uprobe_multi link. The current uprobe is attached through the perf event and attaching many uprobes takes a lot of time because of that. The main reason is that we need to install perf event for each probed function and profile shows perf event installation (perf_install_in_context) as culprit. The new uprobe_multi link just creates raw uprobes and attaches the bpf program to them without perf event being involved. In addition to being faster we also save file descriptors. For the current uprobe attach we use extra perf event fd for each probed function. The new link just need one fd that covers all the functions we are attaching to. v7 changes: - fixed task release on error path and re-org the error path to be more straightforward [Yonghong] - re-organized uprobe_prog_run locking to follow general pattern and removed might_fault check as it's not needed in uprobe/task context [Yonghong] There's support for bpftrace [2] and tetragon [1].

2023-08-21selftests/bpf: Move get_time_ns to testing_helpers.hJiri Olsa
We'd like to have single copy of get_time_ns used b bench and test_progs, but we can't just include bench.h, because of conflicting 'struct env' objects. Moving get_time_ns to testing_helpers.h which is being included by both bench and test_progs objects.

2023-08-21libbpf: Add uprobe multi link support to bpf_program__attach_usdtJiri Olsa
Adding support for usdt_manager_attach_usdt to use uprobe_multi link to attach to usdt probes. The uprobe_multi support is detected before the usdt program is loaded and its expected_attach_type is set accordingly. If uprobe_multi support is detected the usdt_manager_attach_usdt gathers uprobes info and calls bpf_program__attach_uprobe to create all needed uprobes. If uprobe_multi support is not detected the old behaviour stays. Also adding usdt.s program section for sleepable usdt probes.

2023-08-21libbpf: Add uprobe multi link detectionJiri Olsa
Adding uprobe-multi link detection. It will be used later in bpf_program__attach_usdt function to check and use uprobe_multi link over standard uprobe links.

2023-08-21libbpf: Add bpf_program__attach_uprobe_multi functionJiri Olsa
Adding bpf_program__attach_uprobe_multi function that allows to attach multiple uprobes with uprobe_multi link. The user can specify uprobes with direct arguments: binary_path/func_pattern/pid or with struct bpf_uprobe_multi_opts opts argument fields: const char **syms; const unsigned long *offsets; const unsigned long *ref_ctr_offsets; const __u64 *cookies; User can specify 2 mutually exclusive set of inputs: 1) use only path/func_pattern/pid arguments 2) use path/pid with allowed combinations of: syms/offsets/ref_ctr_offsets/cookies/cnt - syms and offsets are mutually exclusive - ref_ctr_offsets and cookies are optional Any other usage results in error.
