2016-07-05block: Switch transfer length bounds to byte-basedEric Blake1-4/+5
Sector-based limits are awkward to think about; in our on-going quest to move to byte-based interfaces, convert max_transfer_length and opt_transfer_length. Rename them (dropping the _length suffix) so that the compiler will help us catch the change in semantics across any rebased code, and improve the documentation. Use unsigned values, so that we don't have to worry about negative values and so that bit-twiddling is easier; however, we are still constrained by 2^31 of signed int in most APIs. When a value comes from an external source (iscsi and raw-posix), sanitize the results to ensure that opt_transfer is a power of 2.

2016-07-05block: Give nonzero result to blk_get_max_transfer_length()Eric Blake1-2/+1
Making all callers special-case 0 as unlimited is awkward, and we DO have a hard maximum of BDRV_REQUEST_MAX_SECTORS given our current block layer API limits. In the case of scsi, this means that we now always advertise a limit to the guest, even in cases where the underlying layers previously use 0 for no inherent limit beyond the block layer.

2016-07-04m25p80: change cur_addr to 32 bit integerPaolo Bonzini1-7/+8
The maximum amount of storage that can be addressed by the m25p80 command set is 4 GiB. However, cur_addr is currently a 64-bit integer. To avoid further problems related to sign extension of signed 32-bit integer expressions, change cur_addr to a 32 bit integer. Preserve migration format by adding a dummy 4-byte field in place of the (big-endian) high four bytes in the formerly 64-bit cur_addr field.

2016-07-04m25p80: avoid out of bounds accessesPaolo Bonzini1-9/+7
s->cur_addr can be made to point outside s->storage, either by writing a value >= 128 to s->ear (because s->ear * MAX_3BYTES_SIZE is a signed integer and sign-extends into the 64-bit cur_addr), or just by writing an address beyond the size of the flash being emulated. Avoid the sign extension to make the code cleaner, and on top of that mask s->cur_addr to s->size.

2016-07-04m25p80: do not put iovec on the stackPaolo Bonzini1-9/+14
When doing a read-modify-write cycle, QEMU uses the iovec after returning from blk_aio_pwritev. m25p80 puts the iovec on the stack of blk_aio_pwritev's caller, which causes trouble in this case. This has been a problem since commit 243e6f6 ("m25p80: Switch to byte-based block access", 2016-05-12) started doing writes at a smaller granularity than 512 bytes. In principle however it could have broken before when using -drive if=mtd,cache=none on a disk with 4K native sectors.

Commit f9e98e5d7a ("xen/blkif: Avoid double access to src->nr_segments") didn't go far enough: src->operation is also being used twice. And nothing was done to prevent the compiler from using the source side of the copy done by blk_get_request() (granted that's very unlikely). Move the barrier()s up, and add another one to blk_get_request(). Note that for completing XSA-155, the barrier() getting added to blk_get_request() would suffice, and hence the changes to xen_blkif.h are more like just cleanup. And since, as said, the unpatched code getting compiled to something vulnerable is very unlikely (and not observed in practice), this isn't being viewed as a new security issue.

2016-06-07virtio-blk: Remove op blocker for dataplaneFam Zheng1-63/+0
Block layer is prepared to unspecialize dataplane, an evidence is this almost complete list of unblocked operations. It has all types except two (actually three if DATAPLANE itself counts but blockdev.c makes sure attaching twice is not possible): MIRROR_TARGET and BACKUP_TARGET. blockdev-mirror refuses to start if target is attached, so the first is not a problem. By removing BACKUP_TARGET, blockdev-backup will become permissive to write to a virtio-blk dataplane disk, but that is not worse than non-dataplane given the latter is already possible. In either case, blockdev.c always checks the target and source are on the same AioContext, or bring them together if possible. Signed-off-by: Fam Zheng <famz@redhat.com> Acked-by: Michael S.

Move it to the actual users. There are still a few includes of qemu/bswap.h in headers; removing them is left for future work. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-12m25p80: Switch to byte-based block accessEric Blake1-16/+7
Sector-based blk_read() should die; switch to byte-based blk_pread() instead. Likewise for blk_aio_readv() and blk_aio_writev(). Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-05-12pflash: Switch to byte-based block accessEric Blake2-12/+12
Sector-based blk_write() should die; switch to byte-based blk_pwrite() instead. Likewise for blk_read(). Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-05-12onenand: Switch to byte-based block accessEric Blake1-14/+27
Sector-based blk_write() should die; switch to byte-based blk_pwrite() instead. Likewise for blk_read(). This particular device picks its size during onenand_initfn(), and can be at most 0x80000000 bytes; therefore, shifting an 'int sec' request to get back to a byte offset should never overflow 32 bits. But adding assertions to document that point should not hurt. Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-05-12nand: Switch to byte-based block accessEric Blake1-13/+23
Sector-based blk_write() should die; switch to byte-based blk_pwrite() instead. Likewise for blk_read(). This file is doing some complex computations to map various flash page sizes (256, 512, and 2048) atop generic uses of 512-byte sector operations. Perhaps someone will want to tidy up the file for fewer gymnastics in managing addresses and offsets, and less wasteful visits of 256-byte pages, but it was out of scope for this series, where I just went with the mechanical conversion.

2016-05-12xen_disk: Switch to byte-based aio block accessEric Blake1-6/+4
Sector-based blk_aio_readv() and blk_aio_writev() should die; switch to byte-based blk_aio_preadv() and blk_aio_pwritev() instead. Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-05-12virtio: Switch to byte-based aio block accessEric Blake1-10/+8
Sector-based blk_aio_readv() and blk_aio_writev() should die; switch to byte-based blk_aio_preadv() and blk_aio_pwritev() instead. The trace is modified at the same time, and nb_sectors is now unused. Fix a comment typo while in the vicinity.

2016-05-12block: Switch blk_read_unthrottled() to byte interfaceEric Blake1-1/+1
Sector-based blk_read() should die; convert the one-off variant blk_read_unthrottled(). Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
