Subject: [PATCH 00/14] Prepare syscall_get_arch for PTRACE_GET_SYSCALL_INFO
Date: Wed, 9 Jan 2019 15:40:44 +0300 [thread overview]
Message-ID: <20190109124044.GA11935@altlinux.org> (raw)
syscall_get_arch() is required to be implemented on all architectures in order
to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request:
syscall_get_arch() is going to be called from ptrace_request() along with
syscall_get_nr(), syscall_get_arguments(), syscall_get_error(), and
syscall_get_return_value() functions with a tracee as their argument.
The primary intent is that the triple (audit_arch, syscall_nr, arg1..arg6)
should describe what system call is being called and what its arguments are.
This patchset began as a series called "Prepare for PTRACE_GET_SYSCALL_INFO",
then I merged it into a series called "ptrace: add PTRACE_GET_SYSCALL_INFO request"
that also contains ptrace-specific changes.
The ptrace-specific part, however, needs more attention to workaround problems
on niche architectures like alpha, while the syscall_get_arch() part is
straightforward, so I decided to split it out into a separate patchset that
just prepares syscall_get_arch() for PTRACE_GET_SYSCALL_INFO: it adds
syscall_get_arch() to those architectures that haven't implemented it yet,
and then adds "struct task_struct *" argument to syscall_get_arch()
on all architectures.
All patches from this patchset have been already reviewed, so it's ready
to be merged without waiting for the ptrace-specific part. As it's all
about syscall_get_arch(), it should probably go via audit tree.
