The O_DIRECT flag imposes alignment restrictions on the length and address of userspace buffers and the file offset of I/Os. While VirtFS/9P has plans to implement O_DIRECT behavior on the server, for now we will stick to a behavior like NFS by bypassing the page cache only on the client. Server may still cache the I/O.

When 9P server fails to create a file due to permission problems it should return EPERM. However the current 9P2000.L code returns EBADF. EBADF is NOT a valid return value from open() call. The problem is because we do not preserve the errno variable properly. If the file open had failed, the call to close() on the fd in v9fs_post_lcreate() fails and sets errno to EBADF. We should preserve the errno that we got from open() and we should call close() only if we had a valid fd.

I reviewed the latest sources of Linux, FreeBSD and NetBSD. They all reset the multiple IA bit (multi_ia in BSD) to zero, but I did not find code which sets this bit to one (like it is done by some routers). Running Windows guests also did not set this bit. Intel's Open Source Software Developer Manual does not give much information on the semantics related to this bit, so I had to guess how it works. The guess was good enough to make the router emulation work. Related changes in this patch: * Update naming and documentation of the internal hash register. It is not limited to multicast, but also used for multiple IA. * Dump complete configuration register when debug traces are enabled. * Debug output when multiple IA bit is set during CmdConfigure. * Debug output when frames are received because multiple IA bit is set, or when they are ignored although it is set.

As status is set to 0 on reset, invoke the relevant callback. This makes for a cleaner code in devices as they don't need to duplicate the code in their reset routine, as well as excercises this path a little more. In particular this makes it possible to unify vhost-net handling code with the following patch. Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).

The addition of memory stats reporting to the virtio balloon causes the 'info balloon' command to become asynchronous. This is a regression because in some cases it can hang the user monitor. This is an alternative to Adam Litke's patch. Adam's patch disabled the corresponding (guest-visible) virtio feature bit, causing issues for migration.

vl.c has a Sun-specific hack to supply a prototype for madvise(), but the call site has apparently moved to arch_init.c. Haiku doesn't implement madvise() in favor of posix_madvise(). OpenBSD and Solaris 10 don't implement posix_madvise() but madvise(). MinGW implements neither. Check for madvise() and posix_madvise() in configure and supply qemu_madvise() as wrapper. Prefer madvise() over posix_madvise() due to flag availability. Convert all callers to use qemu_madvise() and QEMU_MADV_*. Note that on Solaris the warning is fixed by moving the madvise() prototype, not by qemu_madvise() itself. It helps with porting though, and it simplifies most call sites. v7 -> v8: * Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl. v6 -> v7: * Adopt madvise() rather than posix_madvise() semantics for returning errors. * Use EINVAL in place of ENOTSUP. v5 -> v6: * Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID. Spotted by Blue Swirl. v4 -> v5: * Introduce QEMU_MADV_INVALID, suggested by Alexander Graf. Note that this relies on -1 not being a valid advice value. v3 -> v4: * Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl. This will currently break the check in kvm-all.c by calling madvise() with a supported flag, which will not fail. Ideas/patches welcome. v2 -> v3: * Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf. * Add configure check for madvise(), too. Add defines to Makefile, not QEMU_CFLAGS. Convert all callers, untested. Suggested by Blue Swirl. * Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf. * Display configure check results. v1 -> v2: * Don't rely on posix_madvise() availability, add qemu_madvise(). Suggested by Blue Swirl.

IDE is a bit ugly in this respect. For one it doesn't really keep track of a sector size - most of the protocol is in units of 512 bytes, and we assume 2048 bytes for CDROMs which is correct most of the time. Second IDE allocates an I/O buffer long before we know if we're dealing with a CDROM or not, so increase the alignment for the io_buffer unconditionally.
