* slirp: Send RDNSS in RA only if host has an IPv6 DNS serverSamuel Thibault2017-03-291-11/+14
| | | | | | | | | | | | Previously we would always send an RDNSS option in the RA, making the guest try to resolve DNS through IPv6, even if the host does not actually have and IPv6 DNS server available. This makes the RDNSS option enabled only when an IPv6 DNS server is available. Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

* slirp: tcp_listen(): Don't try to close() an fd we never openedPeter Maydell2017-02-261-1/+3
| | | | | | | | | | | | | 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. Not only that, this isn't even the right function to use, because we need closesocket() to do the right thing on Windows. Change to using the right function and only calling it if needed.

* slirp: Convert mbufs to use g_malloc() and g_free()Peter Maydell2017-02-261-16/+14Star
| | | | | | | | | | | The mbuf code currently doesn't check the result of doing a malloc() or realloc() of its data (spotted by Coverity, CID 1238946). Since the m_inc() API assumes that extending an mbuf must succeed, just convert to g_malloc() and g_free().

| | | | | | | | | | | | Check the return value from qemu_socket() rather than trying to pass it to bind() as an fd argument even if it's negative. This wouldn't have caused any negative consequences, because it won't be a valid fd number and the bind call will fail; but Coverity complains (CID 1005723).

* hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_allDaniel P. Berrange2016-09-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

One part of this common code is to do a "memset(m->m_data, 0, m->m_size);" for the related buffer first.
