Michal Rostecki	accd9d2a2a	Add support for LSM programs attached to cgroups ... Kernel 6.0 provides a new attachment type - `BPF_LSM_CGROUP`. When using it, a program attaches to LSM hooks, but only within a cgroup. `BPF_LSM_CGROUP` requires programs to we present in the `lsm_cgroup` section, therefore we provide a new `cgroup_lsm` macro for defining such programs in aya-bpf. We also provide a new `CgroupLsm` structure in userspace aya, which uses the new attachment type and stores the information about cgroup in links.

Michal Rostecki	895f96e971	ebpf: Add TcContext for classifier programs ... This change separates the previous `SkBuffContext` into three structs: * `SkBuff` which is a wrapper around `__sk_buff` which contains all possible methods operating on it. * `SkBuffContext` which is a program context for programs which **cannot** access `__sk_buff` directly and instead can only use `load_bytes`. * `TcContext` which is a classifier context which can access `__sk_buff` directly, hence exposes `data` and `data_end`.

Dave Tucker	dc31e11691	Re-organize into a single workspace ... This commit moves the aya-log projects from the subtree and adds them to the main cargo workspace. It also brings the BPF crates into the workspace and moves the macro crates up a level since they aren't BPF code. Miri was disabled for aya-bpf as the previous config wasn't actually checking anything. CI, clippy, fmt and release configurations have all been adjusted appropriately. CI was not properly running for other supported arches which was also ixed here. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
