Hi,

In this v3:

patch 1 - The fd_is_socket() verification and an update to the comment
          in the code;

patch 2 - The fix for the fd-reuse bug in outgoing_args;

patch 3 - A proposal on how to fix the fd-socket vs. fd-file
          issue. I'm basically moving the fd_is_socket() call earlier
          to be able to do the checks properly.

based-on: https://gitlab.com/peterx/qemu/-/commits/migration-stable

CI run: https://gitlab.com/farosas/qemu/-/pipelines/1214405210

Fabiano Rosas (3):
  migration/multifd: Ensure we're not given a socket for file migration
  migration/multifd: Duplicate the fd for the outgoing_args
  migration: Add fd to FileMigrationArgs
