program: automatic verifier log sizing and ProgramInfo.RecursionMisses()
For the longest time users had to specify
ProgramOptions.LogSizeto get thefull 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
Copy()methods now to a full deep copy and all accept nil values.What's Changed

btf:
bpf_core_type_matchesis now supportedPrograms can now use
bpf_core_type_matches()for a stricter compatibility check. See https://github.com/cilium/ebpf/pull/1366.program, btf: improve debuggability when CO-RE or kfunc fixup fails
The library now tries to return a more informative error when loading a program fails due to a failed CO-RE relocation or a missing kfunc. See https://github.com/cilium/ebpf/pull/1402.
btf: synthesise instruction comments into line info
asm.Commentin an instruction'sSource()are now passed to the kernel in the form of BTF line info. See https://github.com/cilium/ebpf/pull/1417.perf: add WakeupEvents support to Reader
A perf Reader can now be configured to be woken up after a specific number of events / samples have been submitted. See https://github.com/cilium/ebpf/pull/1404.

btf: support for CO-RE relocations against kernel modules
It's now possible to use CO-RE relocations against types defined in kernel modules. See https://github.com/cilium/ebpf/pull/1300 by @brycekahle.

The
linkpackage now allows attaching to netkit interfaces. See https://github.com/cilium/ebpf/pull/1257 by @hemanthmallalink: support for iterating links
The new
link.Iteratortype allows enumerating all BPF links active. See https://github.com/cilium/ebpf/pull/1392 by @mpastyl.Bugfixes

Faster btf.LoadKernelSpec()
Obtaining the kernel's BTF used to be very slow and is now very fast. See https://github.com/cilium/ebpf/pull/1235 by @lmb.
TCX
It's now possible to attach TC programs using the new bpf_link based TCX API. See https://github.com/cilium/ebpf/pull/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 https://github.com/cilium/ebpf/pull/1269 by @olsajiri.
Netfilter link
There is now support to attach Netfilter programs using bpf_links. See https://github.com/cilium/ebpf/pull/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 https://github.com/cilium/ebpf/pull/1209 by @lmb.
Pre-allocate per-CPU values
It's now possible to cut down on allocations by pre-allocating per-CPU values. See https://github.com/cilium/ebpf/pull/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 https://github.com/cilium/ebpf/pull/1192 by @alxn.
Breaking changes
This release requires at least Go 1.21.

This release fixes unmarshaling from a map operation into a
[]byte, see #1180. This is a regression in v0.12.0.We now also properly return an error when the value to unmarshal into is too small, see #1181. This behaviour has existed for a long time.

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.
