2017-04-29slirp: VMStatify remaining except for loopDr. David Alan Gilbert
This converts the remaining components, except for the top level loop, to VMState. Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
2017-04-29slirp: VMStatify socket levelDr. David Alan Gilbert
Working up the stack, this replaces the slirp_socket_load/save with VMState definitions. A place holder for IPv6 support is added as a comment; it needs testing once the rest of the IPv6 code is there.

Coverity points out (CID 1005725) that an error-exit path in tcp_listen() will try to close(s) even if the reason it got there was that the qemu_socket() failed and s was never opened.

2016-09-13hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_allDaniel P. Berrange
The qemu_chr_fe_write method will return -1 on EAGAIN if the chardev backend write would block. Almost no callers of the qemu_chr_fe_write() method check the return value, instead blindly assuming data was successfully sent. In most cases this will lead to silent data loss on interactive consoles, but in some cases (eg RNG EGD) it'll just cause corruption of the protocol being spoken. We unfortunately can't fix the virtio-console code, due to a bug in the Linux guest drivers, which would cause the entire Linux kernel to hang if we delay processing of the incoming data in any way. Fixing this requires first fixing the guest driver to not hold spinlocks while writing to the hvc device backend. Fixes bug: https://bugs.launchpad.net/qemu/+bug/1586756 Signed-off-by: Daniel P.
