v0.16.0

program: automatic verifier log sizing and ProgramInfo.RecursionMisses()

For the longest time users had to specify ProgramOptions.LogSize to get the
full verifier log for large programs. The library now automatically figures out
the correct buffer size to use and the field is deprecated. It will be removed
in the next version.

ProgramInfo now exposes how often a program didn't execute due to recursion
limits via RecursionMisses.

perf, ringbuf: better control over wakeups, Flush()

There is a trade off between how fast samples are processed and how much CPU is
used. Reading samples as quickly as possible uses more CPU, reading in batches
is cheaper.

It's now possible to configure a "maximum time before a wakeup" by using
Reader.SetDeadline(). This now guarantees that any pending samples are read
at the end of the deadline, even if the Watermark wasn't reached.

It's also possible to manually flush the buffer using Flush().

Bugfixes

• The various Copy() methods now to a full deep copy and all accept nil values.
• link: kprobe and uprobe links can now be pinned.

v0.13.0

Faster btf.LoadKernelSpec()

Obtaining the kernel's BTF used to be very slow and is now very fast. See #1235 by @lmb.

TCX

It's now possible to attach TC programs using the new bpf_link based TCX API. See #1163 by @lmb.

UprobeMulti and UretprobeMulti

These are the user-space equivalents to KprobeMulti and Kretprobe multi and allow
attaching to a large number of symbols quickly. See #1269 by @olsajiri.

Netfilter link

There is now support to attach Netfilter programs using bpf_links. See #1313 by @mehrdadrad.

Better ELF section naming compatibility

The list of recognised ELF section names is now automatically generated from
libbpf and should be more accurate and easier to keep up to date. See #1209 by @lmb.

Pre-allocate per-CPU values

It's now possible to cut down on allocations by pre-allocating per-CPU values. See #1220 by @alxn.

Batch operation support for per-CPU values

Batch operations like Map.BatchLookup now support per-CPU values. Note that this
is not particularly optimised, please check whether it is faster based on your
use case. See #1192 by @alxn.

Breaking changes

This release requires at least Go 1.21.

github.com/cilium/ebpf

• (*Map).BatchLookup, (*Map).BatchLookupAndDelete: now take a MapBatchCursor.
  The previous implementation did not properly account for differences between
  map types and was unsafe.

• CORERelocate: now takes an additional argument, which is usually Spec.TypeID.
• MarshalExtInfos: now takes an additional *Builder instead of allocating it.
  Simply pass NewBuilder().

Both of these are considered somewhat internal API of the library.

Full Changelog: v0.12.1...v0.12.2

v0.12.1

Fixes

Fix ProgramInfo.Instructions failing to decode ExtInfos

A recent change to ProgramInfo.Instructions failed to take a difference between kernel and ELF wire format into account. This meant that retrieving the instructions of a program from the kernel failed with a error.

See #1168, fixed by #1169.

Fix reading auxv on 32-bit platforms

The code to determine the kernel version from vdso has been broken on 32-bit platforms. Note that 32-bit arches are not officially supported to the fix is best effort.

See #1133, fixed by #1144.

What's Changed

• internal: fix reading auxv on 32-bit platforms by @lmb in #1144
• perf: clarify purpose of the package by @lmb in #1172
• build(deps): bump urllib3 from 2.0.6 to 2.0.7 in /docs by @dependabot in #1170
• btf: some inflateRawTypes simplifications by @lmb in #1173
• docs: improve Makefile UX with pipenv sync by @ti-mo in #1174
• btf,info: Fix bad instruction offset when parsing infos from kernel by @dylandreimerink in #1169

Full Changelog: v0.12.0...v0.12.1

v0.12.0

This release requires at least Go 1.20. It is mainly a bugfix release without any expected breaking changes. Map operations have also been made faster on the Go side.

Fixes

Correctly freeze .rodata maps

.rodata maps were frozen after programs referring to them were loaded, preventing the verifier from eliminating dead code based on the contents of the .rodata maps. Upgrade if you're running into odd verifier errors that don't occur on libbpf.

See #1159.

Fix fd leak in error path of kfunc support

The library leaked file descriptors when trying to use non-existent kfuncs.

See #1145.

Fix incorrect formatting of signed BTF enums with negative values

Signed enums with negative values were incorrectly formatted, leading to invalid output from bpf2go.

See #1155.

Additions

Map operations using common types are much faster

Keys and values used in map operations were indiscriminately passed through the encoding/binary package. There is now a fast path which skips this step when the in-memory layout of a type is equivalent to the output produced by binary.Write. The result is less allocations and CPU usage.

The optimization doesn't apply to per-CPU maps.

See #1062.
