| |
The call to aio_advance_iovec() in aio_rw_vect_retry() becomes problematic when it comes to pipe and socket operations which internally modify/advance the iovec themselves. As a result AIO writes to sockets fail to return the correct result.
I'm not sure what the best way to fix this is. One option is to always make a copy of the iovec and pass that down. Any other thoughts ?
