Export __receive_fd() so that some modules can use it to pass file descriptor between processes.I really don't think any non-core code should do that, especilly not modular mere driver code.Do you see any issue? Now I think we're able to do that with the help of get_unused_fd_flags() and fd_install() in modules. But we may miss some security stuff in this way. So I try to export __receive_fd() and use it instead.
The real problem is now what helper to use, but rather that random drivers should not just mess with the FD table like that. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
