2016-07-19qapi: Change Netdev into a flat unionEric Blake1-1/+1
This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union. Based on an idea originally by Zoltán Kővágó <DirtY.iCE.hu@gmail.com>: Message-Id: <01a527fbf1a5de880091f98cf011616a78adeeee.1441627176.git.DirtY.iCE.hu@gmail.com> although the sed script in that patch no longer applies due to other changes in the tree since then, and I also did some manual cleanups (such as fixing whitespace to keep checkpatch happy).

2016-06-16os-posix: include sys/mman.hPaolo Bonzini1-1/+0
qemu/osdep.h checks whether MAP_ANONYMOUS is defined, but this check is bogus without a previous inclusion of sys/mman.h. Include it in sysemu/os-posix.h and remove it from everywhere else. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-01-26xen: Switch to libxengnttab interface for compat shims.Ian Campbell1-9/+9
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxengnttab which provides access to grant tables. In preparation for this switch the compatibility layer in xen_common.h (which support building with older versions of Xen) to use what will be the new library API. This means that the gnttab shim will disappear for versions of Xen which include libxengnttab. To simplify things for the <= 4.0.0 support we wrap the int fd in a malloc(sizeof int) such that the handle is always a pointer. This leads to less typedef headaches and the need for XC_HANDLER_INITIAL_VALUE etc for these interfaces. Note that this patch does not add any support for actually using libxengnttab, it just adjusts the existing shims.

2015-07-28xen: Drop net_rx_okFam Zheng1-24/+1
Let net_rx_packet() (which checks the same conditions) drops the packet if the device is not ready. Drop net_xen_info.can_receive and update the return value for the buffer full case. We rely on the qemu_flush_queued_packets() in net_event() to wake up the peer when the buffer becomes available again.
