Bumps github.com/cilium/ebpf from 0.17.3 to 0.19.0.

Release notes

Sourced from github.com/cilium/ebpf's releases.

v0.19.0

Major Performance Improvements

This release includes significant performance optimizations across multiple areas:

Lazy BTF Decoding: BTF types are now decoded on-demand rather than all upfront, dramatically reducing memory usage and load times

Faster Object Opening: Opening Maps and Programs from fd/id/pin is significantly faster through minimal info retrieval

Improved Statistics Access: New Program.Stats() method allows querying runtime statistics without fetching full ProgramInfo

CO-RE Improvements

Full Kernel Module Support: CO-RE relocations now work against all kernel modules, not just vmlinux

Build System and Toolchain Updates

LLVM Toolchain: Updated to support LLVM 14, 17, and 20 (dropped LLVM 11 support)

Enhanced Map Support

BTF Declaration Tags: Added MapSpec.Tags field for reading btf_decl_tag attributes set on maps

Better Error Handling: Improved BPF_F_NO_PREALLOC hints and warnings for map types that require this flag

Assembly and Instruction Handling

Atomic Operations: Complete support for all atomic operations beyond just atomic add

Memory and Variable Access

New Accessors: Added accessor methods for values represented by Variable and Memory types

Windows Support Improvements

Path Canonicalization: Fixed pin path handling to work with eBPF for Windows path canonicalization rules

Bug Fixes

Map Batch Operations: Fixed value unmarshaling for partial batch operations in BatchLookup and BatchLookupDelete (#1741)

Assembly Validation: Return InvalidOpCode for StoreImm with DWord size (#1767)

Builtin Function Calls: Allow negative constants for builtin function calls (#1797)

CO-RE Module Types: Perform CO-RE against all kernel module types (#1511)

Pin API: Made WalkDir harder to misuse and added Windows support (#1652)

Struct Layout: Emit structs.HostLayout in GoFormatter (#1686)

Compatibility Notes

Minimum eBPF for Windows: Now requires eBPF for Windows 0.21.0 or later

LLVM 11 Dropped: No longer supports LLVM 11 (required for declaration tag support)

What's Changed

perf,ringbuf: switch Go build tag by @florianl in cilium/ebpf#1752

pin: make WalkDir harder to misuse and add Windows support by @lmb in cilium/ebpf#1736

examples: remove unnecessary -type flags to bpf2go invocations by @ti-mo in cilium/ebpf#1754

map: unmarshal values for partial batch by @aibor in cilium/ebpf#1742

build(deps): bump golang.org/x/net from 0.36.0 to 0.38.0 by @dependabot in cilium/ebpf#1756
