2014-09-25vpc: fix beX_to_cpu() and cpu_to_beX() confusionStefan Hajnoczi1-22/+22
The beX_to_cpu() and cpu_to_beX() functions perform the same operation - they do a byteswap if the host CPU endianness is little-endian or a nothing otherwise. The point of two names for the same operation is that it documents which direction the data is being converted. This makes it clear whether the data is suitable for CPU processing or in its external representation. This patch fixes incorrect beX_to_cpu()/cpu_to_beX() usage.

2014-09-25docs: add blkdebug block driver documentationStefan Hajnoczi1-0/+161
The blkdebug block driver is undocumented. Documenting it is worthwhile since it offers powerful error injection features that are used by qemu-iotests test cases. This document will make it easier for people to learn about and use blkdebug.

2014-09-25block: Catch simultaneous usage of options and their aliasesKevin Wolf3-2/+82
While thinking about precedence of conflicting block device options from different sources, I noticed that you can specify both an option and its legacy alias at the same time (e.g. readonly=on,read-only=off). Rather than specifying the order of precedence, we should simply forbid such combinations.

2014-09-25block: Specify -drive legacy option aliases in arrayKevin Wolf1-15/+24
Instead of a series of qemu_opt_rename() calls, use an array that contains all of the renames and call qemu_opt_rename() in a loop. This will keep the code readable even when we add an error return to qemu_opt_rename().

2014-09-25block: Keep DriveInfo alive until BlockDriverState diesMarkus Armbruster5-5/+24
If the BDS's refcnt > 0, drive_del() destroys the DriveInfo, but not the BDS. This can happen in three places: * Device model destruction during unplug: blockdev_auto_del() * Xen IDE unplug: pci_piix3_xen_ide_unplug() * drive_del command when no device model is attached: do_drive_del() The other callers of drive_del are on error paths where refcnt == 1. If the user somehow manages to plug in a device model using a BDS that has gone through drive_del(), the legacy configuration passed in DriveInfo doesn't reach the device model, and automatic deletion on unplug doesn't work. Worse, some device models such as scsi-disk crash when DriveInfo doesn't exist. This is theoretical; I didn't research an actual reproducer. The problem was introduced when we replaced DriveInfo reference counting by BDS reference counting in commit a94a3fa..fa510eb. Fix by keeping DriveInfo alive until its BDS dies. This affects qemu_drive_opts: now you can't reuse the same ID for new drive options until the BDS dies. Before, you could, but since the code always attempts to create a BDS with the same ID next, the enclosing operation "create a new drive" failed anyway. Different error path, same result. Unfortunately, the fix involves use of blockdev.c stuff from block.c, which is a layering violation. Fortunately, my forthcoming BlockBackend work will get rid of it again.

When guest sends udp packet with source port and source addr 0, uninitialized socket is picked up when looking for matching and already created udp sockets, and later passed to sosendto() where NULL pointer dereference is hit during so->slirp->vnetwork_mask.s_addr access.
