The qed_bytes_to_clusters() function is normally used with size_t lengths. Consistency check used it with file size length and therefore failed on 32-bit hosts when the image file is 4 GB or more. Make qed_bytes_to_clusters() explicitly 64-bit and update consistency check to keep 64-bit cluster counts.

Some commands are supposed to report a Not Ready Condition (i.e. they require a medium to be present in order to execute successfully). Instead of duplicating the check in each command implementation, let's add a flag and check it before calling the command. This patch only converts existing checks, it does not introduce new checks for any of the other commands that can/should report a Not Ready Condition. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

block_mig_state.total_time is currently the sum of the read request latencies. This is not very accurate because block migration uses aio and so several requests can be submitted at once. Bandwidth should be computed with wall-clock time, not by adding the latencies. In this case, "total_time" has a higher value than it should, and so the computed bandwidth is lower than it is in reality. This means that migration can take longer than it needs to. However, we don't want to use pure wall-clock time here. We are computing bandwidth in the asynchronous phase, where the migration repeatedly wakes up and sends some aio requests. The computed bandwidth will be used for synchronous transfer.

MMC-5 Table F.1 lists errors that can be thrown for the TEST_UNIT_READY command. Going from medium not ready to medium ready states is communicated by throwing an error. This adds the missing 'tray opened' event that we fail to report to guests. After doing this, older Linux guests properly revalidate a disc on the change command. HSM violation errors, which caused Linux guests to do a soft-reset of the link, also go away: ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 sr 1:0:0:0: CDB: Test Unit Ready: 00 00 00 00 00 00 ata2.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 res 01/60:00:00:00:00/00:00:00:00:00/a0 Emask 0x3 (HSM violation) ata2.00: status: { ERR } ata2: soft resetting link ata2.00: configured for MWDMA2 ata2: EH complete Signed-off-by: NAmit Shah <amit.shah@redhat.com> Acked-by: NJes Sorensen <Jes.Sorensen@redhat.com> Tested-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

QEMU can drop a backing file so that an image file no longer depends on the backing file, but this feature has not been exposed in qemu-img. This is useful in an image streaming usecase or when an image file has been fully allocated and no reads can hit the backing file anymore. Since the dropping the backing file can make the image unusable, only allow this when the unsafe flag has been set.

Work around a SPARC glibc bug which caused the epoll_create1 configure test to wrongly claim that the function was present. Some versions of SPARC glibc provided the function in the library but didn't declare it in the include file; the result is that gcc warns about an implicit declaration but a link succeeds. So we reference the function as a value rather than a function call to induce a compile time error if the declaration was not present.

Trace events cannot use %s in their format strings because trace backends vary in how they can deference pointers (if at all).

Quite a number of uid/gid related syscalls are only defined on systems with USE_UID16 defined. This is apperently based on the idea that these system calls would never be called on non-UID16 systems. Make these syscalls available for all architectures that define them. drop alpha hack to support selected UID16 syscalls. MIPS and PowerPC were also defined as UID16, to get uid/gid syscalls available, drop this error as well. Change QEMU to reflect this.
