Hengqi Chen e12e8a9ded aya-bpf/maps: Create LPMTrie with BPF_F_NO_PREALLOC 
The Linux kernel requires BPF_F_NO_PREALLOC on creating LPMTrie ([0]).
Add BPF_F_NO_PREALLOC flag in LPMTrie constructor.

Closes #332.

bpf: Remove unnecessary Sync bound on PerCpuArray<T> 2 years ago
Alessandro Decina 82cd3e695a ebpf: PerCpuArray: remove get_mut() and add get_ptr() and get_ptr_mut() 
get_mut() wasn't sound as it allowed creating multiple mutable
references.

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.

Merge pull request #286 from nak3/add-BPF_MAP_TYPE_BLOOM_FILTER 
Add support for BPF_MAP_TYPE_BLOOM_FILTER
 2 years ago
Kenjiro Nakayama c5d5695a71 Add missing BPF_MAP_TYPE_STACK in BPF code 
Currently BPF_MAP_TYPE_STACK is supported by user code (`aya/src/maps/stack.rs`),
but it does not support the BPF_MAP_TYPE_STACK BPF code.

This patch fixes it.

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.

Tw d1b7b024dc bpf: fix a minor bug due to stackid allocation 
The type casting introduces an allocation, this will cause compiling failure when linking final bpf target.
So remove this casting to fix this issue.

BTW, the following is the failure I met:

= note: 07:24:12 [ERROR] fatal error: "unable to allocate function return #1"
          PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
          Stack dump:
          0.    Running pass 'Function Pass Manager' on module 'trace_bpf-001a275b17e9eb12'.
          1.    Running pass 'BPF DAG->DAG Pattern Instruction Selection' on function '@_ZN7aya_bpf4maps11stack_trace10StackTrace11get_stackid17h32b649bc3780c0aaE'
