Alessandro Decina 665802594c aya: programs: fix syscall name in errors
Alessandro Decina 81a0b61164 aya: 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.
Alessandro Decina b92b1e18a9 aya: improve call relocation error messages
Alessandro Decina 20b2d4c77d aya: BpfError: set the #[source] attribute for RelocationErrors

programs: 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.
Alessandro Decina d085bdb89f CI: add build-test github action
Alessandro Decina 240c65507b bpf: add HashMap::remove()
Alessandro Decina 696ae6079c bpf: Add HashMap::pinned API

Alessandro Decina 31f8d71604 aya: add support for Stack and Queue maps
Alessandro Decina 157c0e2831 bpf: generate bindings for SOL_SOCKET and SO_* socket options 
This is needed for bpf_getsockopt() and bpf_setsockopt()
Alessandro Decina 575e85c412 bpf: add id and pinning fields to bpf_map_def
Alessandro Decina 40b7da6655 aya: add id and pinning fields to bpf_map_def

Alessandro Decina dc4e020f29 aya: netlink: improve error messages
Alessandro Decina 8f55cd728c bpf: SkSkbContext: add ::l3_csum_replace
Alessandro Decina 4febbc3fae bpf: perf_map: fix type error
Alessandro Decina 8e6f447e9b bpf: sk_skb: add helper methods 
This adds support for skb_store_bytes, skb_load_bytes and
l4_csum_replace to SkSkbContext.
Alessandro Decina 274ea91b5e bpf: aya-bpf-bindings: commit generated bindings
Alessandro Decina afcc5dc662 bpf: add support for BPF_PROG_TYPE_SCHED_CLS programs
Alessandro Decina 5effc972ac aya: add support for BPF_PROG_TYPE_SCHED_CLS programs
Alessandro Decina 4222b140ec aya: 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.
Alessandro Decina 3b7ffd0048 aya: update generated bindings 
Update generated bindings with kernel headers from libbpf 4ccc1f0
Alessandro Decina c44393d59b xtask: codegen: use uapi kernel headers from libbpf 
libbpf periodically syncs uapi headers from the kernel. Use those to
generate bindings so that we don't have to rely on distro packages
when we cut releases.
Alessandro Decina 9595bd4571 aya-gen: don't generate doc comments
Alessandro Decina 30d2b25f11 aya: 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.
Alessandro Decina 607cf68a69 aya: xdp: set flags when attaching with netlink
