Federico Ponzi 987e8489d0 aya-utils: add syscall_prefix and syscall_fnname_add_prefix 
These two functions are needed because kernel symbols representing
syscalls have architecture-specific prefixes.

These are the equivalent of bcc's get_syscall_fnname and
get_syscall_prefix.

Solves:
Mary 49c6f5d122 aya: Fix uprobe support on 4.16 and lower 
Fix uprobe support on Ubuntu 18.04.
Mary 8e9f395eab aya: Add support for old ld.so.cache format 
This fix uprobe support on Debian 10. (and possibly others)
This implement support to parse the original libc5 format.
Alexis (Poliorcetics) Bourget 243986c1da fix: Relax unnecessarily strict atomic ordering on probe event_alias
Mary e9be3d9023 aya: Make probe event_alias unique 
This fixes issues when trying to attach the same kernel function multiple times on 4.17 and lower (possibly upper too?)

Mary 591e21267a aya: Do not create data maps on kernel without global data support 
Fix map creation failure when a BPF have a data section on older
kernel. (< 5.2)

If the BPF uses that section, relocation will fail accordingly and
report an error.

Merge pull request from probulate/no-std-inversion 
aya: flip feature "no_std" to feature "std"
Tamir Duberstein 33a0a2b604
aya: flip feature "no_std" to feature "std" 
This fixes `cargo build --all-features` by sidestepping the feature
unification problem described in The Cargo Book[0].

Add `cargo hack --feature-powerset` to CI to enforce that this doesn't
regress (and that all combinations of features work).

Since error_in_core is nightly-only, use core-error and a fake std
module to allow aya-obj to build without std on stable.

Required for kernel before 5.5.

Also move Features to aya-obj.
Mary 7c25fe90a9 aya: Do not use unwrap with btf_fd in bpf_create_map 
Fixes a crash when trying to create a map of type BPF_MAP_TYPE_PERCPU_ARRAY when btf_fd is None.

Tested on Ubuntu 18.04 (4.15.0-202-generic)
Alessandro Decina 93ac3e94bc aya: support relocations across multiple text sections + fixes 
Fix R_BPF_64_64 text relocations in sections other than .text (for
instance .text.unlikely). Also fix misc bugs triggered by integration
tests.
Alessandro Decina 401ea5e848 aya, aya-obj: refactor map relocations 
Clearly split the code between `.maps`, `maps` and data maps (bss, data,
rodata). Sprinkle comments.

Remove MapKind which was effectively only needed since we used to have
one variant - BpfSectionKind::Data - to represent all data maps. Instead
add explicit BpfSectionKind::{Data, Rodata, Bss} variants and match on
those when we initialize maps.

Dave Tucker de4905a24b aya: Add loaded_programs() API to list all loaded programs 
This uses a Programs iterator to yield all loaded bpf programs using
bpf_prog_get_next_id.

Dave Tucker b1a70fc6e4 aya: MapData should be Borrow, not AsRef 
We don't ever do ref-to-ref conversion for MapData so Borrow should
suffice.

Dave Tucker a18693b42d aya: Add support for multibuffer programs 
This adds support for loading XDP programs that are multi-buffer
capable, which is signalled using the xdp.frags section name. When this
is set, we should set the BPF_F_XDP_HAS_FRAGS flag when loading the
program into the kernel.

Dave Tucker 7a720ab0c1 aya: Add from_pin for Programs 
This commit adds from_pin() which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.

This differs from  since it implements this on the concrete program
type, not the Program enum, allowing the user to pass in any additional
context that isn't available from bpf_prog_info.
