Michal Rostecki	33baf7ef22	aya-bpf/maps: Add `get_ptr` and `get_mut_ptr` methods to Array ... Signed-off-by: Michal Rostecki <vadorovsky@gmail.com>	3 years ago
Tatsuyuki Ishi	41c6b56142	bpf: Replace map types to use &self, remove HashMap::get_mut ... The bpf_map_defs are now wrapped with UnsafeCell, which also happens to provide a cozy way to get a *mut pointer. An UnsafeCell isn't strictly required as the struct fields are practically opaque to us, but using an UnsafeCell follows the general best practices against miscompilation and also prevents some obvious errors. HashMap::get_mut was removed because the idea is completely unsound. Previous users should wrap their data with UnsafeCell instead or use atomics.

Thia Wyrod	b655cf973f	aya-bpf: remove unnecessary unsafe markers on map functions. ... Map lookup and deletion can yield stale keys and values by virtue of sharing a data structure with userspace programs and other BPF programs which can modify it. However, all accesses remain perfectly safe and will not cause memory corruption or data races.	4 years ago
