2015-07-22throttle.h: Don't include qemu-common.hdrop-qemu-common-incsPeter Maydell
Replace an include of qemu-common.h with osdep.h and qemu/typedefs.h. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-22event_notifier.h: Don't include qemu-common.hPeter Maydell
Don't include qemu-common.h or windows.h in event_notifier.h; instead include osdep.h and typedefs.h, which is all we need. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-22timer.h: Don't include qemu-common.hPeter Maydell
Include the specific headers we need, rather than qemu-common.h. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-22apic_internal.h: Include cpu.h directlyPeter Maydell
apic_internal.h relies on cpu.h having been included (for the X86CPU type); include it directly rather than relying on it being pulled in via one of the other includes like timer.h. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-22qemu-common.h: Move muldiv64() to host-utils.hPeter Maydell
Move the muldiv64() function from qemu-common.h to host-utils.h. This puts it together with all the other arithmetic functions where we provide a version with __int128_t and a fallback without, and allows headers which need muldiv64() to avoid including qemu-common.h. We don't include host-utils from qemu-common.h, to avoid dragging more things into qemu-common.h than it already has; in practice everywhere that needs muldiv64() can get it via qemu/timer.h.

2015-07-22osdep.h: Add header commentPeter Maydell
Add a header comment to osdep.h, explaining what the header is for and some rules to avoid circular-include difficulties. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21osdep.h: Move some OS header includes and fixups from qemu-common.hPeter Maydell
qemu-common.h has some system header includes and fixups for things that might be missing. This is really an OS dependency and belongs in osdep.h, so move it across. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21qemu-common.h: Move Win32 fixups into os-win32.hPeter Maydell
qemu-common.h includes some fixups for things the Win32 headers don't define or define weirdly. These really belong in os-win32.h, so move them there. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21compiler.h: Use glue() in QEMU_BUILD_BUG_ON definePeter Maydell
Rather than rolling custom concatenate-strings macros for the QEMU_BUILD_BUG_ON macro to use, use the glue() macro we already have (since it's now available to us in this header). Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21osdep.h: Move some compiler-specific things to compiler.hPeter Maydell
osdep.h has a few things which are really compiler specific; move them to compiler.h, and include compiler.h from osdep.h. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21osdep.h: Remove qemu_printfPeter Maydell
qemu_printf is an ancient remnant which has been a simple #define to printf for over a decade, and is used in only a few places. Expand it out in those places and remove the #define. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-07-21qapi/qmp-event.c: Don't manually include os-win32.h/os-posix.hPeter Maydell
qmp-event.c already includes qemu-common.h, so manually including os-win32.h/os-posix.h is unnecessary (and potentially fragile, since it's duplicating the #ifdef logic that chooses which of the two we need). Remove the unnecessary include logic. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2015-07-20net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packetsDana Rubin
Convert partially summed packets to be fully checksummed. In case csum offloaded packet, vmxnet3 implementation always passes an RxCompDesc with the "Checksum calculated and found correct" notification to the OS. This emulates the observed ESXi behavior. Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and place a fully computed checksum into the tcp/udp header. Otherwise, the OS driver will receive a checksum-correct indication but with the actual tcp/udp checksum field having just the pseudo header csum value. If host OS performs forwarding, it will forward an incorrectly checksummed packet.

2015-07-20ahci: Force ICC bits in PxCMD to zeroStefan Fritsch
The AHCI spec requires that the HBA sets the ICC bits to zero after the ICC change is done. Since we don't do any ICC change, force the bits to zero all the time.

The existing short PRDT test case does not transfer any data because the first PRD is less than 1 sector.

2015-07-20virtio-net: Flush incoming queues when DRIVER_OK is being setFam Zheng
This patch fixes network hang after "stop" then "cont", while network packets keep arriving. Tested both manually (tap, host pinging guest) and with Jason's qtest series (plus his "[PATCH 2.4] socket: pass correct size in net_socket_send()" fix). As virtio_net_set_status is called when guest driver is setting status byte and when vm state is changing, it is a good opportunity to flush queued packets. This is necessary because during vm stop the backend (e.g. tap) would stop rx processing after .can_receive returns false, until the queue is explicitly flushed or purged. The other interesting condition in .can_receive, virtio_queue_ready(), is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition is invalid queue index which doesn't need flushing.

2015-07-16crypto: avoid undefined behavior in nettle callsRadim Krčmář
Calling a function pointer that was cast from an incompatible function results in undefined behavior. 'void *' isn't compatible with 'struct XXX *', so we can't cast to nettle_cipher_func, but have to provide a wrapper. (Conversion from 'void *' to 'struct XXX *' might require computation, which won't be done if we drop argument's true type, and pointers can have different sizes so passing arguments on stack would bug.) Having two different prototypes based on nettle version doesn't make this solution any nicer.

memory_region_present() leaks a reference to a MemoryRegion in the case "mr == container". While fixing it, avoid reference counting altogether for memory_region_present(), by using RCU only. The return value could in principle be already invalid immediately after memory_region_present returns, but presumably the caller knows that and it's using memory_region_present to probe for devices that are unpluggable, or something like that. The RCU critical section is needed anyway, because it protects as->current_map. Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
