Direct, unsafe bindings for Linux [`perf_event_open`][man] and friends. +//! +//! Linux's `perf_event_open` system call provides access to the processor's +//! performance measurement counters (things like instructions retired, cache +//! misses, and so on), kernel counters (context switches, page faults), and +//! many other sources of performance information. +//! +//! You can't get the `perf_event_open` function from the `libc` crate, as you +//! would any other system call. The Linux standard C library does not provide a +//! binding for this function or its associated types and constants. +//! +//! Rust analogs to the C types and constants from `<linux/perf_event.h>` and +//! `<linux/hw_breakpoint.h>`, generated with `bindgen`, are available in the +//! [`bindings`] module. +//! +//! There are several ioctls for use with `perf_event_open` file descriptors; +//! see the [`ioctls`] module for those. +//! +//! For a safe and convenient interface to this functionality, see the +//! [`perf_event`] crate. +//! +//! ## Using the raw API +//! +//! As the kernel interface evolves, the struct and union types from the +//! [`bindings`] module may acquire new fields. To ensure that your code will +//! continue to compile against newer versions of this crate, you should +//! construct values of these types by calling their `Default` implementations, +//! which return zero-filled values, and then assigning to the fields you care +//! about. For example: +//! +//! ``` +//! use perf_event_open_sys as sys; +//! +//! // Construct a zero-filled `perf_event_attr`. +//! let mut attrs = sys::bindings::perf_event_attr::default(); +//! +//! // Populate the fields we need. +//! attrs.size = std::mem::size_of::<sys::bindings::perf_event_attr>() as u32; +//! attrs.type_ = sys::bindings::perf_type_id_PERF_TYPE_HARDWARE; +//! attrs.config = sys::bindings::perf_hw_id_PERF_COUNT_HW_INSTRUCTIONS as u64; +//! attrs.set_disabled(1); +//! attrs.set_exclude_kernel(1); +//! attrs.set_exclude_hv(1); +//! +//! // Make the system call. +//! let result = unsafe { +//! sys::perf_event_open(&mut attrs, 0, -1, -1, 0) +//! }; +//! +//! if result < 0 { +//! // ... handle error +//! } +//! +//! // ... use `result` as a raw file descriptor +//! ``` +//! +//! It is not necessary to adjust `size` to what the running kernel expects: +//! older kernels can accept newer `perf_event_attr` structs, and vice versa. As +//! long as the `size` field was properly initialized, an error result of +//! `E2BIG` indicates that the `attrs` structure has requested behavior the +//! kernel is too old to support. +//! +//! When `E2BIG` is returned, the kernel writes the size it expected back to the +//! `size` field of the `attrs` struct. Again, if you want to retry the call, it +//! is not necessary to adjust the size you pass to match what the kernel passed +//! back. The size from the kernel just indicates which version of the API the +//! kernel supports; see the documentation for the `PERF_EVENT_ATTR_SIZE_VER...` +//! constants for details. +//! +//! ## Kernel versions +//! +//! The bindings in this crate are generated from the Linux kernel headers +//! packaged by Fedora as `kernel-headers-5.6.11-100.fc30.x86_64`, which +//! corresponds to `PERF_EVENT_ATTR_SIZE_VER6`. +//! +//! As explained above, bugs aside, it is not necessary to use the version of +//! these structures that matches the kernel you want to run under, so it should +//! always be acceptable to use the latest version of this crate, even if you +//! want to support older kernels. +//! +//! This crate's `README.md` file includes instructions on regenerating the +//! bindings from newer kernel headers. However, this can be a breaking change +//! for users that have not followed the advice above, so regeneration should +//! cause a major version increment. +//! +//! If you need features that are available only in a more recent version of the +//! types than this crate provides, please file an issue. +//! +//! ## Linux API Backward/Forward Compatibility Strategy +//! +//! (This is more detail than necessary if you just want to use the crate. I +//! want to write this down somewhere so that I have something to refer to when +//! I forget the details.) +//! +//! It is an important principle of Linux kernel development that new versions +//! of the kernel should not break userspace. If upgrading your kernel breaks a +//! user program, then that's a bug in the kernel. (This refers to the run-time +//! interface. I don't know what the stability rules are for the kernel headers: +//! can new headers cause old code to fail to compile? Anyway, run time is our +//! concern here.) +//! +//! But when you have an open-ended, complex system call like `perf_event_open`, +//! it's really important for the interface to be able to evolve. Certainly, old +//! programs must run properly on new kernels, but ideally, it should work the +//! other way, too: a program built against a newer version of the kernel +//! headers should run on an older kernel, as long as it only requests features +//! the old kernel actually supports. That is, simply compiling against newer +//! headers should not be disqualifying - only using those new headers to +//! request features the running kernel can't provide should cause an error. +//! +//! Consider the specific case of passing a struct like `perf_event_attr` to a +//! system call like `perf_event_open`. In general, there are two versions of +//! the struct in play: the version the user program was compiled against, and +//! the version the running kernel was compiled against. How can we let old +//! programs call `perf_event_open` on new kernels, and vice versa? +//! +//! Linux has a neat strategy for making this work. There are four rules: +//! +//! - Every system call that passes a struct to the kernel includes some +//! indication of how large userspace thinks that struct is. For +//! `perf_event_open`, it's the `size` field of the `perf_event_attr` +//! struct. For `ioctl`s that pass a struct, it's a bitfield of the +//! `request` value. +//! +//! - Fields are never deleted from structs. At most, newer kernel headers may +//! rename them to '__reserved_foo' or something like that, but once a field +//! has been placed, its layout in the struct never changes. +//! +//! - New fields are added to the end of structs. +//! +//! - New fields' semantics are chosen such that filling them with zeros +//! preserves the old behavior. That is, turning an old struct into a new +//! struct by extending it with zero bytes should always give you a new +//! struct with the same meaning the old struct had. +//! +//! Then, the kernel's strategy for receiving structs from userspace (explained +//! by the kernel comments for `copy_struct_from_user` in +//! `include/linux/uaccess.h`) is as follows: +//! +//! - If the kernel's struct is larger than the one passed from userspace, +//! then that means the kernel is newer than the userspace program. The +//! kernel copies the userspace data into the initial bytes of its own +//! struct, and zeros the remaining bytes. Since zeroed fields have no +//! effect, the resulting struct properly reflects the user's intent. +//! +//! - If the kernel's struct is smaller than the one passed from userspace, +//! then that means that a userspace program compiled against newer kernel +//! headers is running on an older kernel. The kernel checks that the excess +//! bytes in the userspace struct are all zero; if they are not, the system +//! call returns `E2BIG`, indicating that userspace has requested a feature +//! the kernel doesn't support. If they are all zero, then the kernel +//! initializes its own struct with the bytes from the start of the +//! userspace struct, and drops the rest. Since the dropped bytes were all +//! zero, they did not affect the requested behavior, and the resulting +//! struct reflects the user's intent. +//! +//! - In either case, the kernel verifies that any `__reserved_foo` fields in +//! its own version of the struct are zero. +//! +//! This covers both the old-on-new and new-on-old cases, and returns an error +//! only when the call requests functionality the kernel doesn't support. +//! +//! You can find one example of using `perf_event_open` in the [`perf_event`] +//! crate, which provides a safe interface to a subset of `perf_event_open`'s +//! functionality. +//! +//!
