Alessandro Decina ab8d512b60 bpf: add HashMap::insert
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.

don't work consistently for program arrays.

signify that the key is not present.
