2020-12-11iotests: Enable fuse for many testsMax Reitz
Many tests (that do not support generic protocols) can run just fine with FUSE-exported images, so allow them to. Note that this is no attempt at being definitely complete. There are some tests that might be modified to run on FUSE, but this patch still skips them. This patch only tries to pick the rather low-hanging fruits. Note that 221 and 250 only pass when .lseek is correctly implemented, which is only possible with a libfuse that is 3.8 or newer.

2020-07-14iotests: Specify explicit backing format where sensibleEric Blake
There are many existing qcow2 images that specify a backing file but no format. This has been the source of CVEs in the past, but has become more prominent of a problem now that libvirt has switched to -blockdev. With older -drive, at least the probing was always done by qemu (so the only risk of a changed format between successive boots of a guest was if qemu was upgraded and probed differently). But with newer -blockdev, libvirt must specify a format; if libvirt guesses raw where the image was formatted, this results in data corruption visible to the guest; conversely, if libvirt guesses qcow2 where qemu was using raw, this can result in potential security holes, so modern libvirt instead refuses to use images without explicit backing format. The change in libvirt to reject images without explicit backing format has pointed out that a number of tools have been far too reliant on probing in the past. It's time to set a better example in our own iotests of properly setting this parameter. iotest calls to create, rebase, and convert are all impacted to some degree. It's a bit annoying that we are inconsistent on command line - while all of those accept -o backing_file=...,backing_fmt=..., the shortcuts are different: create and rebase have -b and -F, while convert has -B but no -F. (amend has no shortcuts, but the previous patch just deprecated the use of amend to change backing chains).

2020-01-06iotests: Replace IMGOPTS= by -oMax Reitz
Tests should not overwrite all user-supplied image options, but only add to it (which will effectively overwrite conflicting values). Accomplish this by passing options to _make_test_img via -o instead of $IMGOPTS. For some tests, there is no functional change because they already only appended options to IMGOPTS. For these, this patch is just a simplification. For others, this is a change, so they now heed user-specified $IMGOPTS. Some of those tests do not work with all image options, though, so we need to disable them accordingly.

2015-09-04iotests: Do not suppress segfaults in bash testsMax Reitz
Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a segmentation fault, that message is invisible in most cases since the output is generally filtered and bash suppresses the segmentation fault notice for any but the last element of a pipe. Most of the time, the test will then fail anyway because of missing output, but not necessarily (as happened with test 82 recently). Fix this by making the corresponding environment variables point to wrapper functions which execute the respective command in a subshell. Giving options to qemu/qemu-io/qemu-img and path names with spaces were broken for the Python tests; this patch "accidentally" fixes that.

2014-05-19qemu-iotests: Fix core dump suppression in test 039Markus Armbruster
The shell script attempts to suppress core dumps like this: old_ulimit=$(ulimit -c) ulimit -c 0 $QEMU_IO arg... ulimit -c "$old_ulimit" This breaks the test hard unless the limit was zero to begin with! ulimit sets both hard and soft limit by default, and (re-)raising the hard limit requires privileges. Broken since it was added in commit dc68afe. Could be fixed by adding -S to set only the soft limit, but I'm not sure how portable that is in practice. Simply do it in a subshell instead, like this: (ulimit -c 0; exec $QEMU_IO arg...)

2014-04-04qcow2: Flush metadata during read-only reopenKevin Wolf
If lazy refcounts are enabled for a backing file, committing to this backing file may leave it in a dirty state even if the commit succeeds. The reason is that the bdrv_flush() call in bdrv_commit() doesn't flush refcount updates with lazy refcounts enabled, and qcow2_reopen_prepare() doesn't take care to flush metadata. In order to fix this, this patch also fixes qcow2_mark_clean(), which contains another ineffective bdrv_flush() call beause lazy refcounts are disabled only afterwards. All existing callers of qcow2_mark_clean() either don't modify refcounts or already flush manually, so that this fixes only a latent, but not yet actually triggerable bug. Another instance of the same problem is live snapshots. Again, a real corruption is prevented by an explicit flush for non-read-only images in external_snapshot_prepare(), but images using lazy refcounts stay dirty.
