2020-04-30iotests: Filter testfiles out in filter_img_info()Kevin Wolf1-2/+3
We want to keep TEST_IMG for the full path of the main test image, but filter_testfiles() must be called for other test images before replacing other things like the image format because the test directory path could contain the format as a substring. Insert a filter_testfiles() call between both.

2020-04-30block: truncate: Don't make backing file data visibleKevin Wolf1-0/+25
When extending the size of an image that has a backing file larger than its old size, make sure that the backing file data doesn't become visible in the guest, but the added area is properly zeroed out. Consider the following scenario where the overlay is shorter than its backing file: base.qcow2: AAAAAAAA overlay.qcow2: BBBB When resizing (extending) overlay.qcow2, the new blocks should not stay unallocated and make the additional As from base.qcow2 visible like before this patch, but zeros should be read. A similar case happens with the various variants of a commit job when an intermediate file is short (- for unallocated): base.qcow2: A-A-AAAA mid.qcow2: BB-B top.qcow2: C--C--C- After commit top.qcow2 to mid.qcow2, the following happens: mid.qcow2: CB-C00C0 (correct result) mid.qcow2: CB-C--C- (before this fix) Without the fix, blocks that previously read as zeros on top.qcow2 suddenly turn into A.

If BDRV_REQ_ZERO_WRITE is set and we're extending the image, calling qcow2_cluster_zeroize() with flags=0 does the right thing: It doesn't undo any previous preallocation, but just adds the zero flag to all relevant L2 entries. If an external data file is in use, a write_zeroes request to the data file is made instead.

2020-04-30qemu-iotests: allow qcow2 external discarded clusters to contain stale dataPaolo Bonzini2-5/+14
Test 244 checks the expected behavior of qcow2 external data files with respect to zero and discarded clusters. Filesystems however are free to ignore discard requests, and this seems to be the case for overlayfs. Relax the tests to skip checks on the external data file for discarded areas, which implies not using qemu-img compare in the data_file_raw=on case. This fixes docker tests on RHEL8.

Make it simpler: visit_start_struct(v, NULL, NULL, 0, &err); if (err) { goto out; } - - if (!err) { - visit_check_struct(v, &err); - } + visit_check_struct(v, &err); visit_end_struct(v, NULL); if (err) { goto out; } Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20200424084338.26803-16-armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2020-04-30qapi: Assert non-input visitors see only valid alternate tagsMarkus Armbruster1-0/+1
An alternate type's visit_type_FOO() fails when it runs into an invalid ->type. This is appropriate with an input visitor: visit_start_alternate() sets ->type according to the input, and bad input can lead to bad ->type. It should never happen with an output, clone or dealloc visitor: if it did, the alternate being output, cloned or deallocated would be messed up beyond repair. Assert that.

2020-04-30qapi: Clean up visitor's recovery from input with invalid typeMarkus Armbruster1-0/+3
An alternate type's visit_type_FOO() fails when it runs into an invalid ->type. If it's an input visit, we then need to free the the object we got from visit_start_alternate(). We do that with qapi_free_FOO(), which uses the dealloc visitor. Trouble is that object is in a bad state: its ->type is invalid. So the dealloc visitor will run into the same error again, and the error recovery skips deallocating the alternate's (invalid) alternative. Works, because qapi_free_FOO() ignores the error. Avoid it instead: free the messed up object with by g_free().

2020-04-29riscv: Fix Stage2 SV32 page table walkAnup Patel1-6/+1
As-per RISC-V H-Extension v0.5 draft, the Stage2 SV32 page table has 12bits of VPN[1] and 10bits of VPN[0]. The additional 2bits in VPN[1] is required to handle the 34bit intermediate physical address coming from Stage1 SV32 page table. The 12bits of VPN[1] implies that Stage2 SV32 level-0 page table will be 16KB in size with total 4096 enteries where each entry maps 4MB of memory (same as Stage1 SV32 page table). The get_physical_address() function is broken for Stage2 SV32 level-0 page table because it incorrectly computes output physical address for Stage2 SV32 level-0 page table entry. The root cause of the issue is that get_physical_address() uses the "widened" variable to compute level-0 physical address mapping which changes level-0 mapping size (instead of 4MB). We should use the "widened" variable only for computing index of Stage2 SV32 level-0 page table.

2020-04-29riscv/sifive_u: Add a serial property to the sifive_u machineBin Meng2-0/+21
At present the board serial number is hard-coded to 1, and passed to OTP model during initialization. Firmware (FSBL, U-Boot) uses the serial number to generate a unique MAC address for the on-chip ethernet controller. When multiple QEMU 'sifive_u' instances are created and connected to the same subnet, they all have the same MAC address hence it creates a unusable network. A new "serial" property is introduced to specify the board serial number. When not given, the default serial number 1 is used.
