[$] Modifying another process's system calls

Date:
Tue, 14 Jan 2025 17:47:44 +0000

Description:
The ptrace() system call allows a suitably privileged process to modify 
another in a
large number of ways.  Among other things, ptrace() can intercept
system calls and make changes to them, but such operations can be fiddly
and architecture-dependent. This patch series from
Dmitry Levin seeks to improve that situation by adding a new ptrace() 
operation to make changes to another process's system
calls in an architecture-independent manner.
