Subject: slirp: fix structure initialization in tcp_listen()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ab07b980c442b4f94f8fe9c236d7702c19bf2c74;p=qemu.git

slirp: fix structure initialization in tcp_listen()

A data structure of type sockaddr_in is allocated from stack but not
properly initialized. This may lead to a failure in the bind() call
later on. Fixed by filling the contents of the structure with zeroes
before using it.
