Fixes issue where bpf.get_syscall_fnname() on ARM64 returns bare syscall name instead of the prefixed _arm64_sys variant, causing kprobe attachment failures. Now detects ARM64 prefix alongside x64 (x64_sys) and generic (sys) prefixes.

Subject: [PATCH] Add ARM64 syscall prefix detection in C++ API
|
|
|
|
Fixes issue where bpf.get_syscall_fnname() on ARM64 returns bare
|
|
syscall name instead of the prefixed __arm64_sys_ variant, causing
|
|
kprobe attachment failures. Now detects ARM64 prefix alongside x64
|
|
(__x64_sys_) and generic (sys_) prefixes.
|
|
|
|
Fixes: #5350
