Split off qemu-testsuite.spec to decouple retriggering the sometimes-failing tests from the lengthy build of the binaries. Extend test coverage to include iotests for block backends. Drop the SUSE-only MAC address warning for now, to keep output-checking tests from failing. Re-enable glusterfs support for Factory (updated to v3.6.2). Re-enable libseccomp support for armv7l (submission of patched v2.2.0 pending).

Subject: [PATCH] linux-user: lseek: explicitly cast non-set offsets to signed
|
|
|
|
When doing lseek, SEEK_SET indicates that the offset is an unsigned variable.
|
|
Other seek types have parameters that can be negative.
|
|
|
|
When converting from 32bit to 64bit parameters, we need to take this into
|
|
account and enable SEEK_END and SEEK_CUR to be negative, while SEEK_SET stays
|
|
absolute positioned which we need to maintain as unsigned.
