Floppy uses the DMA controller in rc4030 chipset, and not the i8259 from the ISA bus. It's better to disable DMA than to call the wrong DMA controller.

2016-02-03fdc: fix detection under LinuxJohn Snow1-0/+16
Accidentally, I removed a "feature" where empty drives had geometry values applied to them, which allows seek on empty drives to work "by accident," as QEMU actually tries to disallow that. Seeks on empty drives should work, though, but the easiest thing is to restore the misfeature where empty drives have non-zero geometries applied. Document the hack accordingly. [Maintainer edit] This fix corrects a regression introduced in d5d47efc, where pick_geometry was modified such that it would not operate on empty drives, and as a result if there is no diskette inserted, QEMU no longer populates it with geometry bounds. As a result, seek fails when QEMU denies to move the current track, but reports success anyway. This can confuse the guest, leading to kernel panics in the guest.

When processing 'sendkey' command, hmp_sendkey routine null terminates the 'keyname_buf' array. This results in an OOB write issue, if 'keyname_len' was to fall outside of 'keyname_buf' array. Since the keyname's length is known the keyname_buf can be removed altogether by adding a length parameter to index_from_key() and using it for the error output as well.

2016-02-02block: set device_list.tqe_prev to NULL on BDS removalJeff Cody3-12/+16
This fixes a regression introduced with commit 3f09bfbc7. Multiple bugs arise in conjunction with live snapshots and mirroring operations (which include active layer commit). After a live snapshot occurs, the active layer and the base layer both have a non-NULL tqe_prev field in the device_list, although the base node's tqe_prev field points to a NULL entry. This non-NULL tqe_prev field occurs after the bdrv_append() in the external snapshot calls change_parent_backing_link(). In change_parent_backing_link(), when the previous active layer is removed from device_list, the device_list.tqe_prev pointer is not set to NULL. The operating scheme in the block layer is to indicate that a BDS belongs in the bdrv_states device_list iff the device_list.tqe_prev pointer is non-NULL. This patch does two things: 1.) Introduces a new block layer helper bdrv_device_remove() to remove a BDS from the device_list, and 2.) uses that new API, which also fixes the regression once used in change_parent_backing_link().

The added parameter can be used to return the BDS pointer which the valid offset is referring to. Its value should be ignored unless BDRV_BLOCK_OFFSET_VALID in ret is set. Until block drivers fill in the right value, let's clear it explicitly right before calling .bdrv_get_block_status. The "bs->file" condition in bdrv_co_get_block_status is kept now to keep iotest case 102 passing, and will be fixed once all drivers return the right file pointer.
