Add a special function to reset the host usb device. It tracks the time needed by the USBDEVFS_RESET ioctl and prints a warning in case it needs too long. Usually it should be finished in 200 - 300 miliseconds. Warning threshold is one second. Intention is to help troubleshooting by indicating that the usb device stopped responding even to a reset request and is possibly broken. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This patch makes iPXE work with the rtl8139 emulation. The rtl8139 driver in iPXE issues a 16bit access on the ChipCmd register (offset 0x37) to check the status of the rx buffer. The offset of the ioport access was getting fixed up to 0x36 in qemu, causing the value read in iPXE to be invalid. This fixes an issue with iPXE reporting timeouts during TFTP transfers. Reposting this here because it is trivial enough and the original post on qemu-devel didn't attract much attention. Also, the inw() which was causing the issue has been replaced with an inb() in upstream iPXE: https://git.ipxe.org/ipxe.git/commit/91dd64ad25baa27954a7518e73df4fca8a2d0c93Signed-off-by: NJulian Pidancet <julian.pidancet@gmail.com> Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com>

Use qdev_init() instead of qdev_init_nofail(), usb device initialization can fail, most common case being port and device speed mismatch. Handle failures correctly and pass up NULL pointers then. Also fixup usb_create_simple() callers (only one was buggy) to properly check for NULL pointers before referncing the usb_create_simple() return value.

get_str_sep() can fail, but net_slirp_hostfwd_remove() doesn't check. Works, because it initializes buf[] to "", which get_str_sep() doesn't touch when it fails. Coverity doesn't like it, and neither do I. Change it to work exactly like slirp_hostfwd().

Change the default on x86 Linux hosts to building PIE (position independent executables); instead of restricting the option to user-only targets, apply it to all targets. In addition, set the relocation sections to read-only (relro) when available; this reduces the attack surface by disallowing changes to relocation tables at runtime. While PIE reduces performance and relro increases load time, it greatly improves security, with the potential to reduce a code execution vulnerability to a self denial of service. Non-x86 are not changed, as they require TCG changes; neither are non-Linux, due to lack of test coverage.

Image files have two types of data: immutable data that describes things like image size, backing files, etc. and mutable data that includes offset and reference count tables. Today, image formats aggressively cache mutable data to improve performance. In some cases, this happens before a guest even starts. When dealing with live migration, since a file is open on two machines, the caching of meta data can lead to data corruption. This patch addresses this by introducing a mechanism to invalidate any cached mutable data a block driver may have which is then used by the live migration code. NB, this still requires coherent shared storage. Addressing migration without coherent shared storage (i.e. NFS) requires additional work. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This lets different subsystems register an Error that is thrown whenever migration is attempted. This works nicely because it gracefully supports things like hotplug. Right now, if multiple errors are registered, only one of them is reported. I expect that for 1.1, we'll extend query-migrate to return all of the reasons why migration is disabled at any given point in time.
