Currently the qemu user-mode networking stack reads the host DNS configuration (/etc/resolv.conf or the Windows equivalent) only once when qemu starts. This causes name lookups in the guest to fail if the host is moved to a different network from which the original DNS servers are unreachable, a common occurrence when the host is a laptop. This patch changes the slirp code to read the host DNS configuration on demand, caching the results for at most 1 second to avoid unnecessary overhead if name lookups occur in rapid succession. On non-Windows hosts, /etc/resolv.conf is re-read only if the file has been replaced or if its size or mtime has changed.

Three problems with our_addr: - It's determined only once when qemu starts, but the address can change (just like the DNS configuration can). - It's supposed to be the IP address of a host network interface, but there's no guarantee that gethostbyname(gethostname()) actually does that: the host might be a laptop that has only a loopback interface up, or the hostname might be localhost.localdomain, etc. - It's useless at best: get_dns_addr() calls it, there's no reason to send DNS requests to a different IP address if you're running a DNS server on the host and resolv.conf points to 127.0.0.1. These problems are easily solved by removing the code. Signed-off-by: NEd Swierk <eswierk@aristanetworks.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

With that patch applied "-balloon virtio,args" becomes a shortcut for "-device virtio-balloon-pci,args". Side effects: - ballon device gains support for id=<tag>. - ballon device is off by default now. - initialization order changes, which may in different pci slot assignment depending on the VM configuration.

The current IDE code uses an array of two IDEState structs to maintain the IDE bus. This patch adds a IDEBus to be used instead and does a bunch of cleanups: * move ide bus state from IDEState to IDEBus. * drop a bunch of ugly pointer arithmetics to figure the active interface, explicitly save the interface number instead. * add helper functions to save/restore idebus state. It also fixes a save/restore bug: loadvm allways stores the command in the master's IDEState, even when it was saved from the slave.

This patch adds some functions for error reporting to address the problem that error messages should be routed to different destinations depending on the context of the caller, i.e. monitor command errors should go to the monitor, command line errors to stderr. qemu_error() is a printf-like function to report errors. qemu_errors_to_file() and qemu_errors_to_mon() switch the destination for the error message to the specified file or monitor. When setting a new destination the old one will be kept. One can switch back using qemu_errors_to_previous(). i.e. it works like a stack. main() calls qemu_errors_to_file(stderr), so errors go to stderr by default. monitor callbacks are wrapped into qemu_errors_to_mon() + qemu_errors_to_previous(), so any errors triggered by monitor commands will go to the monitor. Each thread has its own error message destination. qemu-kvm probably should add a qemu_errors_to_file(stderr) call to the i/o-thread initialization code.

Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

Hello, the real world issue is that the hardware allows sends up to 2600 bytes, and for some reason FreeBSD sometimes sends frames larger than the ethernet frame size (102+1460 is the maximum I have seen so far), overflowing the on-stack tx buffer of the driver. Independent of that, the code should avoid allowing the guest to overwrite the stack. This is a minimal patch to fix the issue (you could leave out the size change of the buf array as well, networking still seems to work either way). Obviously there are better ways to handle it, but a proper fix IMO would involve first getting rid of the code duplication and given the number of patches pending for that code I see no point in working on that now.

If a flash file of size smaller than the flash size is specified in the -pflash option, the block driver returns error. But the pflash_cfi0x ignores the error. This results in a flash content of all zeroes. And the simulation aborts while executing code. This patch adds the checks for errors from bdrv_read and escalates it to the calling code.

cpu_synchronize_state() is a little unreadable since the 'modified' argument isn't self-explanatory. Simplify it by making it always synchronize the kernel state into qemu, and automatically flush the registers back to the kernel if they've been synchronized on this exit.

-watchdog NAME is now equivalent to -device NAME, except it treats option argument '?' specially, and supports only one watchdog. A side effect is that a device created with -watchdog may now receive a different PCI address. i6300esb is now available on any machine with a PCI bus, not just PCs. ib700 is still PC only, but that could be changed easily. The only remaining use of struct WatchdogTimerModel and watchdog_add_model() is supporting '-watchdog ?'. Should be replaced by searching device_info_list for watchdog devices when we can identify them there. Also fixes ib700 not to use vm_clock before it is initialized: in wdt_ib700_init(), called from register_watchdogs(), which runs before init_timers(). The bug made ib700_write_enable_reg() crash in qemu_del_timer(). Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The bdrv_aio_{read,write} routines can return a NULL pointer when the I/O submission fails. Currently we ignore this and will wait forever for an I/O completion and leading to a hang of the guest. I can easily reproduce this using the native Linux AIO patch, but it's also possible using normal pthreads-based AIO.
