[Minios-devel] [UNIKRAFT PATCH 0/6] lib/syscall_shim: Handling binary system calls

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

This series introduces support for handling Linux-style binary system call
requests with the syscall_shim library. The syscall_shim library provides
handling of indirect system calls (like documented with `man syscall(2)`)
which is also needed to handle binary system call requests: The system call
number is handed over as argument to the system call request.

However, the convention of error handling is different between the binary
syscall ABI and the libc level. For this purpose the concept of "libc-style"
and "raw" system call implementions is introduced.

This patch series depends on the series:
 "Support for binary system calls (x86_64, KVM for now)"
 (https://patchwork.unikraft.org/project/unikraft/list/?series=1082)
