Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.12.0 (2024-02-28)

Chore

Use the cargo workspace package table This allows for inheritance of common fields from the workspace root. The following fields have been made common:
- authors
- license
- repository
- homepage
- edition
Appease clippy unused imports
tracefs review fixes

Chore

Don't use path deps in workspace This moves the path dependencies back into the per-crate Cargo.toml. It is required such that the release tooling can correctly calculate which version constraints require changing when we perform a release.

Documentation

Document breaking changes This provides a BREAKING-CHANGES.md that we can populate per-crate. Doing so will allow us to pull this content into our changelog and websites to make things easier for users.
Add labels for optional features Following the lead of crates like tokio and nix, we now annotate APIs that require optional features. This helps in cases where a user wants to have an AsyncPerfEventArray which is documented on crates.io, but it's not obvious that you have to enable the async feature.

Bug Fixes

invalid transmute when calling fd Corrent an invalid transmutation for sock_map. fd is already a ref of MapFd, so transmuting &fd to &SockMapFd is equivalent to transmuting &&SockMapFd into &SockMapFd which is buggy.
Relax unnecessarily strict atomic ordering on probe event_alias
remove useless any all in cfg.

Other

reformat to please rustfmt
export some missing modules Previously we were only re-exporting the program types from these, so links and other pub types were not exported.
perf_event: add inherit argument to attach()

add SchedClassifier::attach_to_link Similar to Xdp::attach_to_link, can be used to replace/upgrade the program attached to a link.
add SchedClassifierLink::attach_type() getter The link already exposes priority() and handle(). Expose attach_type() too.
Fix ringbuf docs doctests are not running in CI and therefore the didn't catch the ringbuf docs failures. This commit fixes the issues in the examples.
pin for (async)perf_event_array Implement pinning for perf_event_array and async_perf_event_array. Additionally make the core MapData.pin method operate on a reference rather than a mutable reference.
make RingBuf: Send + Sync There was no reason for them not to be -- the APIs all require mutable references and hold onto mutable references, so there cannot be internal concurrency. The !Send + !Sync came from the MMap, but not for any good reason.
extracting program and map names with the same function
add MapInfo struct following the same pattern as ProgramInfo This makes the APIs for loading maps and programs more similar.
support loading a map by fd This adds support to loading maps by fd similarly to the way programs can be loaded by fd.
make KernelVersion::code public
Add markdownlint This adds a linter to catch common markdown formatting errors. The linter used is markdownlint-cli2 which is available on all platforms and has an associated Github Action to automate these checks in CI.

Configuration is checked in at .markdownlint-cli2.yaml.

You may run the check locally using markdownlint-cli2. Or you may install the extension for VSCode: DavidAnson.vscode-markdownlint

updated-dependencies:
- dependency-name: async-io dependency-type: direct:production ...
fix unused async-io dependency linter error Not using the dep: syntax created a Cargo feature flag for async-io, though this feature alone does nothing without the async_std or async_tokio features.
Implement RingBuf This implements the userspace binding for RingBuf.

Instead of streaming the samples as heap buffers, the process_ring function takes a callback to which we pass the event's byte region, roughly following [libbpf]'s API design. This avoids a copy and allows marking the consumer pointer in a timely manner.
move mmap from perf_buffer.rs to sys/mod.rs mmap() is needed for the ring buffer implementation, so move it to a common module
impl Fromobj::InvalidMapTypeError for MapTypeError
sort variants Missed in 5e637071c1 due to merge skew with 7b71c7e1cd.
import types from std::ffi rather than libc
sort variants
remove redundant keys default-features = false is already in the root Cargo.toml.
add pin() api
- Adds new maps_mut() API to the BpfManager to allow us to iterate though and pin all of maps at the same time.
- Adds new pin(Path)/unpin(Path) api to Maps so they can be generically pinned AFTER load.
- Adds macro for pinning explicit map types in aya. Convert all explicit map types "inner" field to be pub crate in order to facilitate this.
fix libbpf_pin_by_name Aligns with libbpf for the special LIBBPF_PIN_BY_NAME map flag. Specifically if the flag is provided without a pin path default to "/sys/fs/bpf".
Deprecate syscall_prefix Using the prefix only for the host architecture is often not enough, kernels usually provide symbols for more architectures, which are used by multilib applications. Handling them might or might not be necessary depending on the use case. Due to that complexity, we decided to let the callers to handle prefixes the way they prefer.
group_imports = "StdExternalCrate" High time we stop debating this; let the robots do the work.
Fix program loading on kernels with a patch > 255
fix load time and add test Time since boot is defined as the UNIX_EPOCH plus the duration since boot. which is realtime - boottime NOT boottime - realtime.

Add a integration test to ensure this doesn't happen again.
make maps work on kernels not supporting ProgIds On startup, the kernel is probed for support of chained program ids for CpuMap, DevMap and DevMapHash, and will patch maps at load time to have the proper size. Then, at runtime, the support is checked and will error out if a program id is passed when the kernel does not support it.
use ProgramFd instead of impl AsRawFd Not having a generic here allows to pass None without specifying the actual type you don't care about.
add documentation for XDP maps
fix docstring missing trailing period
add support for chained xdp programs in {cpu,dev}map set/insert functions can now take an optional bpf program fd to run once the packet has been redirected from the main probe
add support for map-bound XDP programs Such programs are to be bound to cpumap or devmap instead of the usual network interfaces.
Update XDP maps implementations Map impls changed since this was first written.
Implement XDP Map Types This commit adds implementations for:
- xskmap
- devmap
- devmap_hash
- cpumap
Which can all be used to redirect XDP packets to various different locations
Make MapData::pin pub This is to solve a use-case where a user (in this case bpfd) may want to:
- MapData::from_pin to open a pinned map from bpffs
- MapData::pin to pin that object into another bpffs
Both operations should be easily accomplished without needing to cast a MapData into a concrete Map type - e.g aya::maps::HashMap.
Remove MapData::pinned BPF objects can be pinned multiple times, to multiple different places. Tracking whether or not a map is pinned in a bool is therefore not sufficient. We could track this in a HashSet, but there is really no reason to track it at all.
fix typos, avoid fallible conversions
MapData::{obj, fd} are private
MapFd and SockMapFd are owned
add program_info() api to program Add a new api to the outer level Program structure which allows users to get the program's kernel info before casting it to an explicit program variant.
support TryFrom for LRU hash maps The macro to implement TryFrom for MapData didn't have the ability to specify that more than one variant of MapData can be valid for a single map implementation. Support for new syntax was added to the macro so that the implementation can succeed for both valid variants in the HashMap and PerCpuHashMap impl.
rework TryFrom macros The old macros were repetitive and inflexible. This unifies the various macros used to generate TryFrom implementations for map implementations from the relevant map enum variants.

Cleanup in anticipation of fixing #636.

The API changes are just about renaming the return to Self and Self::Error; they are not real changes.
access inner through async Avoid holding onto raw file descriptors.

Remove some implied bounds (BorrowMut implies Borrow).
ProgAttachLink and LircLink hold owned FDs
use OwnedFd
Use AsFd when attaching fds to programs This is a breaking change but adds another level of safety to ensure the file descriptor we receive is valid. Additionally, this allows aya to internally easily duplicate this file descriptor using std library methods instead of manually calling dup which doesn't duplicate with the CLOSE_ON_EXEC flag that is standard pratice to avoid leaking the file descriptor when exec'ing.
Use BorrowedFd when using the program fd in sys/bpf.rs This commit reveals but does not address a file descriptor leak in LircLink2::query. This function returns a list of LircLinks where each of them have a program file descriptor that is not going to be closed. This commit does not add this leak; it merely makes it louder in the code.
support non-UTF8 probing
avoid path UTF-8 assumptions
deny various allow-by-default lints
fix docs build Appease the new lint rustdoc::redundant_explicit_links that was added in https://github.com/rust-lang/rust/pull/113167.
BloomFilter::insert takes &mut self This is consistent with all the other maps.
MapData::fd is non-optional The primary driver of change here is that MapData::create is now a factory function that returns Result<Self, _> rather than mutating &mut self. The remaining changes are consequences of that change, the most notable of which is the removal of several errors which are no longer possible.
use RAII to close FDs
ProgramData::attach_prog_fd is owned This prevents a file descriptor leak when extensions are used.

This is an API breaking change.
ProgramFd is owned
add helper methods for ProgramInfo
- Add helper methods to get useful information from the ProgramInfo object which is returned by the loaded_programs() API. Specifically this code mirrors the bpftool prog command in terms of useful fields.
- Add a new API macro to each aya Program type to allow us to fetch its accompanying ProgramInfo metadata after its been loaded.
- Add a new ProgramInfo constructor that builds a new instance using a raw fd.
- Add a smoke test for the loaded_programs() API as well as all the relevant methods on the ProgramInfo type.
Plug attach_btf_obj_fd leak
Don't store bpf_fd in MapData This is only used in create and therefore can be passed as a parameter.
refactor btf_obj_get_info_by_fd to share code
add map_ids to bpf_prog_get_info_by_fd Allows the caller to pass a slice which the kernel will populate with map ids used by the program.
avoid vector allocation when parsing ksyms
Use OwnedFd in FdLink.
Remove name from ProgramSection The name here is never used as we get the program name from the symbol table instead.
refactor target resolution This attempts to do fewer lossy conversions and to avoid some allocations.
extract library path resolving The function is extracted so that a test could be written. This test is valid on linux-gnu targets, and it doesn't need any special privileges. This is in anticipation of removing the code that uses this functionality (seemingly incidentally) from integration tests.
Set BPF_F_SLEEPABLE for sleepable programs
preallocate the vector This code badly needs tests :(
plug file descriptor leak This leaked a file descriptor if bpf_prog_get_info_by_fd failed.
push error construction up
make loaded_programs opaque
extract common SyscallError We currently have 4 copies of this.
sys_bpf takes mut ref Some syscalls mutate the argument, we can't be passing an immutable reference here.
avoid repeating BPF_BTF_LOAD dance
Return OwnedFd for perf_event_open. This fixes a file descriptor leak when creating a link of BPF_PERF_EVENT attach type.
better panic messages Always include operands in failing assertions. Use assert_matches over manual match + panic.
Use Arc when loading BTF fd This fixes an existing file descriptor leak when there is BTF data in the loaded object.

To avoid lifetime issues while having minimal impact to UX the OwnedFd returned from the BPF_BTF_LOAD syscall will be wrapped in an Arc and shared accross the programs and maps of the loaded BPF file.
Make SysResult generic on Ok variant
bpf_prog_get_fd_by_id returns OwnedFd
Define dependencies on the workspace level This way we will avoid version mismatches and make differences in features across our crates clearer.
Ignore embedded BTF error if not truely required This allows fallback to BTF manual relocation when BTF loading fail when not truely required.
compile C probes using build.rs
- Add libbpf as a submodule. This prevents having to plumb its location around (which can't be passed to Cargo build scripts) and also controls the version against which codegen has run.
- Move bpf written in C to the integration-test crate and define constants for each probe.
- Remove magic; each C source file must be directly enumerated in the build script and in lib.rs.
don't allocate static strings
Make Features part of the public API This commit adds a new probe for bpf_attach_cookie, which would be used to implement USDT probes. Since USDT probes aren't currently supported, we this triggers a dead_code warning in clippy.

There are cases where exposing FEATURES - our lazy static - is actually helpful to users of the library. For example, they may wish to choose to load a different version of their bytecode based on current features. Or, in the case of an orchestrator like bpfd, we might want to allow users to describe which features their program needs and return nice error message is one or more nodes in their cluster doesn't support the necessary feature set.

To do this without breaking the API, we make all the internal members of the Features and BtfFeatures structs private, and add accessors for them. We then add a features() API to avoid leaking the lazy_static.
Remove iter_key from LPM Trie API Based on the discussion in Discord we've decided to drop the iter_key() API for LPM Trie. According to the kernel self-tests and experimentation done in Aya, providing a key into bpf_map_get_next_id will either:
- If key is an EXACT match, proceed iterating through all keys in the trie from this point
- If key is NOT an EXACT match, proceed iterating through all keys in the trie starting at the leftmost entry.
An API in Aya could be crafted that gets the LPM match + less specific matches for a prefix using these semantics BUT it would only apply to userspace. Therefore we've opted out of fixing this.
replace os::unix::prelude with os::fd
allow global value to be optional This allow to not error out when a global symbol is missing from the object.
add syscall_prefix and syscall_fnname_add_prefix These two functions are needed because kernel symbols representing syscalls have architecture-specific prefixes.

These are the equivalent of bcc's get_syscall_fnname and get_syscall_prefix.
Fix uprobe support on 4.16 and lower Fix uprobe support on Ubuntu 18.04.
Add support for old ld.so.cache format This fix uprobe support on Debian 10. (and possibly others) This implement support to parse the original libc5 format.
Make probe event_alias unique This fixes issues when trying to attach the same kernel function multiple times on 4.17 and lower (possibly upper too?)
Do not create data maps on kernel without global data support Fix map creation failure when a BPF have a data section on older kernel. (< 5.2)

If the BPF uses that section, relocation will fail accordingly and report an error.

updated-dependencies:
- dependency-name: object dependency-type: direct:production ...
flip feature "no_std" to feature "std" This fixes cargo build --all-features by sidestepping the feature unification problem described in The Cargo Book[0].

Add cargo hack --feature-powerset to CI to enforce that this doesn't regress (and that all combinations of features work).

Since error_in_core is nightly-only, use core-error and a fake std module to allow aya-obj to build without std on stable.

[0] https://doc.rust-lang.org/cargo/reference/features.html#feature-unification
Correctly set the kernel code version for Debian kernel Fix BPF syscall failure related to the kernel code version.
Correctly set the kernel code version for Ubuntu kernel Fix BPF syscall failure related to the kernel code version.
Add sanitize code for kernels without bpf_probe_read_kernel Required for kernel before 5.5.

Also move Features to aya-obj.
Do not use unwrap with btf_fd in bpf_create_map Fixes a crash when trying to create a map of type BPF_MAP_TYPE_PERCPU_ARRAY when btf_fd is None.

Tested on Ubuntu 18.04 (4.15.0-202-generic)
support relocations across multiple text sections + fixes Fix R_BPF_64_64 text relocations in sections other than .text (for instance .text.unlikely). Also fix misc bugs triggered by integration tests.
make it possible to use set_global() with slices of Pod(s)
make it possible to use set_global() with slices of Pod(s)
Allow to attach XDP probe by interface index
Fix MapData Clone implementation The Clone implementation of MapData was previously not storing the result of the dup operation.
Add loaded_programs() API to list all loaded programs This uses a Programs iterator to yield all loaded bpf programs using bpf_prog_get_next_id.
MapData should be Borrow, not AsRef We don't ever do ref-to-ref conversion for MapData so Borrow should suffice.
Fix is_perf_link_supported This was mistakenly comparing the exit code of the syscall, which is always -1 and not the corresponding error-code. Added unit tests to ensure we don't regress.
More discrete feature logging Just use the Debug formatter vs. printing a message for each probe.
Enable bpf_link for perf_attach programs This adds support for bpf_link to PerfEvent, Tracepoint, Kprobe and Uprobe programs.
Add probe for bpf_link_create for perf programs
Make features a lazy_static
Add support for multibuffer programs This adds support for loading XDP programs that are multi-buffer capable, which is signalled using the xdp.frags section name. When this is set, we should set the BPF_F_XDP_HAS_FRAGS flag when loading the program into the kernel.
Add from_pin for Programs This commit adds from_pin() which allows the creation of a Program from a path on bpffs. This is useful to be able to call attach or other APIs for programs that are already loaded to the kernel.

This differs from #444 since it implements this on the concrete program type, not the Program enum, allowing the user to pass in any additional context that isn't available from bpf_prog_info.
fix Lru and LruPerCpu hash maps They were broken by https://github.com/aya-rs/aya/pull/397
update documentation and versioning info
- Set the version number of aya-obj to 0.1.0.
- Update the description of the aya-obj crate.
- Add a section in README and rustdoc warning about the unstable API.
add basic documentation to public members Types relevant to maps are moved into aya_obj::maps. Some members are marked pub(crate) again.
migrate aya::obj into a separate crate To split the crate into two, several changes were made:
1. Most pub(crate) are now pub to allow access from Aya;
2. Parts of BpfError are merged into, for example, RelocationError;
3. BTF part of Features is moved into the new crate;
4. #![deny(missing_docs)] is removed temporarily;
5. Some other code gets moved into the new crate, mainly:
  - aya::{bpf_map_def, BtfMapDef, PinningType},
  - aya::programs::{CgroupSock*AttachType},
The new crate is currenly allowing missing_docs. Member visibility will be adjusted later to minimize exposure of implementation details.
migrate bindgen destination
make btf::RelocationError private
fix regression computing pointer sizes Computing pointer sizes was broken in #285
fix detaching links on drop
add missing TryFrom for HashMap, PerCpuHashMap and LpmTrie

- dependency-name: object dependency-type: direct:production ...
Fix the error message in MapData::pin() The syscall name is BPF_OBJ_PIN, not BPF_OBJ_GET.
Remove unused dependencies
Disable miri warnings about integer-to-pointer conversions override_syscall performs integer-to-pointer conversion. This is considered harmful on the newest Rust nightly which provides ptr::from_exposed_addr, but there is no other way on Rust stable than doing as *const T, which is what miri is unhappy about.
add BpfLoader::set_max_entries Add BpfLoader::set_max_entries, which sets the max_entries for the specified map, as the load-time option. The max_entries set at map initialization in the ebpf component can be overwritten by this method called on the userspace component. If you want to set max_entries for multiple maps in an ebpf component, you can do so by calling set_max_entries in the form of a method chain.
Rename from_pinned and from_path to from_pin
Fix review comments from #387
Add integration test for pinning lifecycle
Replace From for XdpLink with TryFrom
Rename bpf_obj_get_info_by_id
fix miss doc period
change variant names
More pinning fixes This commit fixes a bug and adds some missing lifecycle APIs.
1. Adds PinnedLink::from_path to create a pinned link from bpffs
2. Adds From for FdLink to allow for ^ to be converted
3. Adds From for XdpLink
Fix segfault in define_link_wrapper The From<$wrapper> for $base implemention is refers to itself, eventually causing a segfault.
Improved BTF Type API This commit removes reliance on generated BtfType structs, as well as adding a dedicated struct for each BTF type. As such, we can now add nice accessors like bits() and encoding() for Int vs. inlined shift/mask operations.
update VerifierLogLevel to use bitflags
Fix Link Pinning
1. Removes OwnedLink
2. Allows Links to be converted into FdLink
3. Introduces a PinnedLink type to handle wrap FdLink when pinned and support un-pinning
update VerifierLogLevel level variants
use enum to set verifier log level
expose BPF verifier log level configuration
Remove MapError::InvalidPinPath
Use PinError for all pinning errors
Implement FdLink::pin() This allows for FdLinks to also be pinned to BpfFs. In order for it to be called, the user would first call take_link to get the underlying link. This can then be destructured to an FdLink where FdLink::pin() may be called.
Allow pin to be used on all programs This allows for pin to be called as Xdp::pin() or Program::pin() - the same way that unload() can be used. This simplifies the use of this API.
Fix rlimit warning on for 32bit systems
Raise the RLIMIT_MEMLOCK warning only if failed to create a map Also, mention that setting the RLIMIT_MEMLOCK to a higher value is an option.
Raise the warning when RMILIT_MEMLOCK is not RLIM_INFINITY Kernels before 5.11 don't use cgroup accounting, so they might reach the RLIMIT_MEMLOCK when creating maps. After this change, we raise a warning recommending to raise the RLIMIT_MEMLOCK.
Fix latest nightly lints
update object requirement from 0.28 to 0.29 Updates the requirements on object to permit the latest version.

Improve Extension Docs
Add Extension::attach_to_program() This allows for Extension programs already loaded to the kernel to be attached to another program that is BTF-compatible with the one provided at load() time
Replace ProgramFd trait with struct This removes the ProgramFd trait with a struct that wraps a RawFd. Program::fd() has been implemented as well as fd() for each Program Type. This allows for a better API than requiring the use of the ProgramFd trait.
Implement attach_to_link for XDP
Add support for bpf_link_update
Add Map::fd() function to return a MapFd
Add crabby, sync with aya/README.md
Implement BPF_PROG_TYPE_CGROUP_SOCK
Unload programs on drop

Test

avoid lossy string conversions We can be strict in tests.
s/assert!(.*) ==/assert_eq!\1,/ One case manually adjusted to assert_matches!.
add the possibility to run a test inside a network namespace For tests that do networking operations, this allows to have a clean-state network namespace and interfaces for each test. Mainly, this avoids "device or resource busy" errors when reusing the loopback interface across tests.

Relocate maps using symbol_index Since we support multiple maps in the same section, the section_index is no longer a unique way to identify maps. This commit uses the symbol index as the identifier, but falls back to section_index for rodata and bss maps since we don't retrieve the symbol_index during parsing.
revert version to 0.10.7 The world isn't ready to have pre-releases in git
rework links Remove LinkRef and remove the Rc<RefCell<_>> that was used to store type-erased link values in ProgramData. Among other things, this allows Bpf to be Send, which makes it easier to use it with async runtimes.

Change the link API to:
```
let link_id = prog.attach(...)?;
...
prog.detach(link_id)?;
```
Link ids are strongly typed, so it's impossible to eg:
```
let link_id = uprobe.attach(...)?;
xdp.detach(link_id);
```
As it would result in a compile time error.

Links are still stored inside ProgramData, and unless detached explicitly, they are automatically detached when the parent program gets dropped.
Support multiple maps in map sections This commit uses the symbol table to discover all maps inside an ELF section. Instead of doing what libbpf does - divide the section data in to equal sized chunks - we read in to section data using the symbol address and offset, thus allowing us to support definitions of varying lengths.
perf_buffer: call BytesMut::reserve() internally This changes PerfBuffer::read_events() to call BytesMut::reserve() internally, and deprecates PerfBufferError::MoreSpaceNeeded.

This makes for a more ergonomic API, and allows for a more idiomatic usage of BytesMut. For example consider:
```
let mut buffers = vec![BytesMut::with_capacity(N), ...];
loop {
    let events = oob_cpu_buf.read_events(&mut buffers).unwrap();
    for buf in &mut buffers[..events.read] {
        let sub: Bytes = buf.split_off(n).into();
        process_sub_buf(sub);
    }
    ...
}
```
This is a common way to process perf bufs, where a sub buffer is split off from the original buffer and then processed. In the next iteration of the loop when it's time to read again, two things can happen:
- if processing of the sub buffer is complete and sub has been dropped, read_events() will call buf.reserve(sample_size) and hit a fast path in BytesMut that will just restore the original capacity of the buffer (assuming sample_size <= N).
- if processing of the sub buffer hasn't ended (eg the buffer has been stored or is being processed in another thread), buf.reserve(sample_size) will actually allocate the new memory required to read the sample.
In other words, calling buf.reserve(sample_size) inside read_events() simplifies doing zero-copy processing of buffers in many cases.

Bug Fixes

make maps compatible with kernel <= 4.14 In kernel 4.15 and additional parameter was added to allow maps to have names but using this breaks on older kernels.

This change makes it so the name is only added on kernels 4.15 and newer.

Other

fix lint errors
Improve documentation of set_global method Use static instead of const and mention the necessity of using core::ptr::read_volatile.
Fix Loading from cgroup/skb sections fa037a88e2 allowed for cgroup skb programs that did not specify an attach direction to use the cgroup/skb section name per the convention established in libbpf. It did not add the necessary code to load programs from those sections which is added in this commit
implement Pod for arrays of Pod types If a type is POD (meaning it can be converted to a byte array), then an array of such type is POD.
update parking_lot requirement from 0.11.1 to 0.12.0 Updates the requirements on parking_lot to permit the latest version.

- Commits
updated-dependencies:
- dependency-name: parking_lot dependency-type: direct:production ...
fix func_info/line_info offsets Given the new start instruction offset, rebase func_infos and line_infos.
relocate .text references Handle relocations against .text symbols in all instructions not just calls. Makes it so that let x = &some_function triggers linking of some_function in the current program and handles the resulting relocation accordingly.

Among other things, enables the use of bpf_for_each_map_elem.
Replace / in DATASEC before load to kernel This replaces the / character with a . which is allowed in the kernel names. Not allowing a forward slash is perhaps a kernel bug, but lets fix it up here as it's commonly used for Aya
fix match arms Don't match on kind and use if let... Match on the BtfType
add a test for each BTF fix
fix borrow check errors
Merge Fixup and Sanitzation to single step Aya will now perform sanitzation and fixups in a single phase, requiring only one pass over the BTF. This modifies the parsed BTF in place.
Fix BTF verifier output Currently errors can occur if the verifier output is > buffer as we get ENOMEM. We should only provide a log_buf if initial load failed, then retry up to 10 times to get full verifier output.

To DRY this logic it has been moved to a function so its shared with program loading
fix sanitization if BTF_FUNC_GLOBAL is not supported The lower 16 bits were not actually being cleared.
fixup func protos If an argument has a type, it must also have a name, see btf_func_check in the kernel.
run fixup in place
Fix name truncation
Truncate long program names
Add support for BTF_TYPE_KIND_{TAG,DECL_TAG} Adds support for two new BTF kinds including feature probes and BTF sanitization
Fix BTF type resolution for Arrays and Ints The union of size and type is unused in BTF_KIND_ARRAY. Type information of elements is in the btf_array struct that follows in the type_ field while the index type is in the index_type field.

For BTF_KIND_INT, only the offset should be compared and size and signedness should be ignored.
maps: rename from_pinned() to open_pinned()
Retrieve program from pinned path
allocate func/line_info buffers outside if the pointer isn't valid in the current code!
document the public api
Add fixup for PTR types from Rust
Add Btf::to_bytes This allows for parsed BTF to be re-encoded such that it could be loaded in to the kernel. It moves bytes_of to the utils package. We could use Object::bytes_of, but this requires the impl of the Pod trait on generated code.
Fix for rename of BPF_ -> BPF_CORE_
update object requirement from 0.27 to 0.28 Updates the requirements on object to permit the latest version.

updated-dependencies:
- dependency-name: object dependency-type: direct:production ...
Remove unnecessary unsafe markers on map iteration. Map iteration can yield stale keys and values by virtue of sharing a data structure with BPF programs which can modify it. However, all accesses remain perfectly safe and will not cause memory corruption or data races.
eliminate name duplication in maps and programs. Map and ProgramData objects had unnecessarily cloned strings for their names, despite them being just as easily available to external users via bpf.maps() and bpf.programs().
use correct program name when relocating
Improve section detection This commit improves section detection. Previously, a section named "xdp_metadata" would be interpretted as a program section, which is incorrect. This commit first attempts to identify a BPF section by name, then by section.kind() == SectionKind::Text (executable code). The computed section kind is stored in the Section so variants can be easily matched on later.
remove unnecessary usage of &dyn trait in favor of impl trait. This should improve performance in most situations by eliminating unnecessary fat pointer indirection.
programs_mut iterator to complement programs.
close file descriptors on Map drop.
expand include_bytes_aligned to accept expressions. This allows one to this macro with literal expressions involving macros such as concat! and env!.
fix test warnings

fix include_bytes_aligned! macro to work in some corner cases I found a corner case in my own development workflow that caused the existing macro to not work properly. The following changes appear to fix things. Ideally, we could add some test cases to CI to prevent regressions. This would require creating a dedicated directory to hold test cases so that we can "include" them at compile time.
introduce include_bytes_aligned!() macro This is a helper macro that can be used to include bytes at compile-time that can then be used in Bpf::load(). Unlike std's include_bytes!(), this macro also ensures that the resulting byte array is correctly aligned so that it can be parsed as an ELF binary.

minor PerfEvent API tweaks
run xtask codegen aya
only consider Text symbols as relocatable functions
fix bug with nested call relocations Use the correct offset when looking up relocation entries while doing nested call relocations.
update authors and repository link
Fix size of Unknown variant The size of Unknown should be ty_size, otherwise when it is encountered, we never advance the cursor and it creates an infinite loop.

v0.10.3 (2021-07-31)

Bug Fixes

pass BTF object by reference in order to allow multiple eBPF programs to share it and save memory (closes #30).

Other

programs: tweak LircMode2::query doc.
netlink: fix clippy lint
fix clippy warnings
tc: add qdisc_detach_program qdisc_detach_program can be used to detach all the programs that have the given name. It's useful when you want to detach programs that were attached by some other process (eg. iproute2), or when you want to detach programs that were previously left attached because the program that attached them was killed.
netlink: fix alignment when writing attributes
netlink: fix handling of multipart messages
tc: clean up netlink code a bit
fix formatting
fix clippy warnings
obj: improve parse_map_def tests Add a test that checks that we handle ELF section padding correctly and simplify the other tests.
don't error out parsing padded map sections
tc: make qdisc_add_clsact return io::Error
kprobe: remove pid argument Kprobes can only be attached globally. Per-pid logic needs to be implemented on the BPF side with bpf_get_current_pid_tgid.
add minimum kernel version for each map and program type
add missing load() in kprobe example
support both bpf_map_def layout variants Libbpf and iproute2 use two slightly different bpf_map_def layouts. This change implements support for loading both.
netlink: tc: use ptr::read_unaligned instead of deferencing a potentially unaligned ptr
netlink: port TC code to using new nlattr utils
netlink: refactor nlattr writing code
netlink: introduce NestedAttrs builder and switch XDP to it NestedAttrs is a safe interface for writing nlattrs. This is the first step towards making the netlink code safer and easier to maintain.
refactor program section parsing This renames aya::obj::ProgramKind to aya::obj::ProgramSection and moves all the program section parsing to ProgramSection::from_str.
fix tracepoint prefix in a couple more places
fix trace point section name Trace points have prefix "tracepoint" not "trace_point".

v0.10.0 (2021-06-15)

Other

add more fields to Cargo.toml
bump version to 0.10
add doc aliases for maps and programs
refactor tc code a bit and add docs
improve async perf map docs
tweak PerfEventArray docs
ProgramArray: more doc fixes
ProgramArray: tweak docs
implement ProgramFd for CgroupSkb
fix CgroupSkb docs
programs: add support for BPF_PROG_TYPE_CGROUP_SKB programs
programs: fix detaching programs attached with bpf_prog_attach
programs: fix syscall name in errors
handle reordered functions LLVM will split .text into .text.hot .text.unlikely etc and move the content around in order to improve locality. We need to parse all the text sections or relocations can potentially fail.
improve call relocation error messages
BpfError: set the #[source] attribute for RelocationErrors
add support for attaching and detaching TC programs This change adds support for attaching TC programs directly from aya, without having to use iproute2/tc.
add support for Stack and Queue maps
add id and pinning fields to bpf_map_def
netlink: improve error messages
add support for BPF_PROG_TYPE_SCHED_CLS programs
perf_map: fix bug when max_entries=0 When a perf map has max_entries=0, max_entries is dynamically set at load time to the number of possible cpus as reported by /sys/devices/system/cpu/possible.

This change fixes a bug where instead of setting max_entries to the number of possible cpus, we were setting it to the cpu index of the last possible cpu.
update generated bindings Update generated bindings with kernel headers from libbpf 4ccc1f0
xdp: fix detaching on kernels older than 5.7 XDP_FLAGS_REPLACE was added in 5.7. Now for kernels >= 5.7 whenever we detach an XDP program we pass along the program fd we expect to be detaching. For older kernels, we just detach whatever is attached, which is not great but it's the way the API worked pre XDP_FLAGS_REPLACE.
xdp: set flags when attaching with netlink
fix BpfError display strings
fix warnings
programs: rework load_program() retry code a bit
programs: add support for SkMsg programs
maps: add SockHash
add support for SockOps programs
add support BPF_PROG_TYPE_SK_SKB programs and SockMaps
fix program array key size
small doc fixes
more docs
consolidate errors into ProgramError::SyscallError
split aya::programs::probe into ::kprobe and ::uprobe & add docs
add maps::StackTraceMap Map type for BPF_MAP_TYPE_STACK_TRACE.
add util::kernel_symbols() kernel_symbols() can be used to load /proc/kallsyms in a BTreeMap. Useful for looking up symbols from stack addresses.
add bpf_map_lookup_elem_ptr
tweak docs
rename ProgramArray::unset to ProgramArray::clear_index
rename ProgramArray::keys to ProgramArray::indices
maps: add PerCpuArray
rework IterableMap and ProgramArray Make MapKeys not use IterableMap. Leave only ProgramArray::get, ProgramArray::set and ProgramArray::unset exposed as the other syscalls don't work consistently for program arrays.
PerCpuKernelMem doesn't need to be public
add aya::maps::Array
add aya::maps::array and move ProgramArray under it
hash_map: add doc aliases for HASH and LRU_HASH
per_cpu_hash_map: add support for BPF_MAP_TYPE_LRU_PERCPU_HASH
maps: introduce MapError::KeyNotFound Change get() from -> Result<Option, MapError> to -> Result<V, MapError> where MapError::KeyNotFound is returned instead of Ok(None) to signify that the key is not present.
rename MapError::NotFound to MapError::MapNotFound
add PerCpuHashMap
move hash_map.rs to hash_map/hash_map.rs
hash_map: factor out common hash code This is in preparation of adding new hash map types
fix warnings
don't export VerifierLog
HashMap: add support for LRU maps
more docs
tweak docs
rename perf map and add docs Rename the perf_map module to just perf, and rename PerfMap to PerfEventArray.
maps: add docs and make the hash_map and program_array modules public
add HashMap docs
make HashMap::new private
add ProgramArray docs
make ProgramArray::new private
remove pop() lookup_and_delete_elem is only supported for QUEUE and STACK maps at the moment.
add some docs for the crate and Bpf
maps: group syscall errors into MapError::SyscallError
fix bindings for PERF_EVENT_IOC_{ENABLE|DISABLE|SET_BPF}
remove TryInto magic from program()/program_mut() too For programs it's actually useful being able to get the underlying Program enum, for example when iterating/loading all the programs
remove TryInto cleverness from map() and map_mut() Require callers to call try_into() explicitly. It's more characters, but it's easier to understand/document.

Also introduce MapError::NotFound instead of returning Result<Option<_>>.
fix some badly completed match arms
fix verifier log handling
add support for function calls
section: collecting relocations can't fail anymore
obj: rename symbol_table to symbols_by_index
add Program::name() and make ::prog_type() public
bpf: Add Bpf::programs()
bpf: remove lifetime param from previous signature
maps: add Map::name() and Map::map_type()
add Bpf::maps() to get all the maps
switch to rustified enums
generate code with xtask
xdp BPF_LINK_CREATE was added in 5.9
obj: implement sane defaults for license and kernel version Default to license=GPL and kernel_version=any
implement missing bit of retprobes
sys: fix warning
rename gen-bindings to gen-bindings.sh
tweak error display
support max_entries=0 When a PerfMap has max_entries=0, set max_entries to the number of available CPUs.
add possible_cpus()
enable only the std feature for the futures crate
add explicit BTF argument to the load API Add a target_btf: Option<Btf> argument to Bpf::load. None can be passed to indicate to skip BTF relocation, for example for kernels that don't support it. Some(btf) can be used to pass BTF parsed with Btf::from_sys_fs() or Btf::parse/parse_file.

Finally, add a simpler Bpf::load_file(path) that uses from_sys_fs() internally to simplify the common case.
add support for attaching with custom xdp flags
rework ProgramError a bit Move type specific errors to XdpError SocketFilterError etc.

Annotate all source errors with #[source]
add internal API to create links
fail new() for high level wrappers if the underlying map hasn't been created
remove unused methods
add AsyncPerfMap When the async_tokio or async_std features are enabled, AsyncPerfMap provides an async version of PerfMap which returns a future from read_events()
split in sub modules
implement AsRawFd
