Subject: AIO operation and CMSG
Date: Sun, 14 Jan 2018 09:01:00 +0100	[thread overview]
Message-ID: <6214924.yszrlpR4T4@positron.chronox.de> (raw)

Hi,

I am working on the user space library providing a wrapper to the AF_ALG user 
space interface [1]. The AF_ALG interface supports asynchronous operation 
which is utilized with the io_* system calls, including io_submit. All works 
as expected.

The syscall io_submit sends data to the kernel and invokes the respective 
handler function in the kernel such as the recvmsg handler. What I am 
wondering is whether there is a way to send CMSG data along with the io_submit 
syscall? If not, is CMSG handling with the AIO syscalls possible at all?

Thank you very much.
