* | s390x/sclp: properly guard pci-specific functionsCornelia Huck2017-08-301-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we do not provide zpci, pci reconfiguration via sclp is not available either. I/O adapter configuration, however, should always be present. Rename the values that refer to I/O adapter configuration (instead of only pci) to make things clearer. Move length checking of the sccb for I/O adapter configuration into the common sclp code (out of the pci code). This also fixes an issue that the pci code would refer to a field in the sccb before checking whether it was actually long enough. Check for the adapter type in the sccb and return unrecognized adapter type if the guest tries to issue I/O adapter configure/deconfigure for a type other than pci or for pci if the zpci facility is not provided.

* hw/ppc/spapr: Fix segfault when instantiating a 'pc-dimm' without 'memdev'Thomas Huth2017-08-221-1/+1
| | | | | | | | | | | | | | | | | | | | QEMU currently crashes when trying to use a 'pc-dimm' on the pseries machine without specifying its 'memdev' property. This happens because pc_dimm_get_memory_region() does not check whether the 'memdev' property has properly been set by the user. Looking closer at this function, it's also obvious that it is using &error_abort to call another function - and this is bad in a function that is used in the hot-plugging calling chain since this can also cause QEMU to exit unexpectedly. So let's fix these issues in a proper way now: Add a "Error **errp" parameter to pc_dimm_get_memory_region() which we use in case the 'memdev' property has not been set by the user, and which we can use instead of the &error_abort, and change the callers of get_memory_region() to make use of this "errp" parameter for proper error checking.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.

| * rcu: completely disable pthread_atfork callbacks as soon as possiblePaolo Bonzini2017-08-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of -daemonize, system mode QEMU sometimes needs to fork() and keep RCU enabled in the child. However, there is a possible deadlock with synchronize_rcu: - the CPU thread is inside a RCU critical section and wants to take the BQL in order to do MMIO - the monitor thread, which is owning the BQL, calls rcu_init_lock which tries to take the rcu_sync_lock - the call_rcu thread has taken rcu_sync_lock in synchronize_rcu, but synchronize_rcu needs the CPU thread to end the critical section before returning. This cannot happen for user-mode emulation, because it does not have a BQL. To fix it, assume that system mode QEMU only forks in preparation for exec (except when daemonizing) and disable pthread_atfork as soon as the double fork has happened.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | MIPS KVM trap & emulate guest kernels have a different segment layout compared with traditional MIPS kernels, to allow both the user and kernel code to run from the user address segment without repeatedly trapping to KVM. QEMU currently supports this layout only for KVM, but its sometimes useful to be able to run these kernels in QEMU on a PC, so enable it for TCG too. This also paves the way for MIPS KVM VZ support (which uses the normal virtual memory layout) by abstracting whether user mode kernel segments are in use.

| * block: Skip implicit nodes in query-block/blockstatsKevin Wolf2017-07-242-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits 0db832f and 6cdbceb introduced the automatic insertion of filter nodes above the top layer of mirror and commit block jobs. The assumption made there was that since libvirt doesn't do node-level management of the block layer yet, it shouldn't be affected by added nodes. This is true as far as commands issued by libvirt are concerned. It only uses BlockBackend names to address nodes, so any operations it performs still operate on the root of the tree as intended. However, the assumption breaks down when you consider query commands, which return data for the wrong node now. These commands also return information on some child nodes (bs->file and/or bs->backing), which libvirt does make use of, and which refer to the wrong nodes, too. One of the consequences is that oVirt gets wrong information about the image size and stops the VM in response as long as a mirror or commit job is running: https://bugzilla.redhat.com/show_bug.cgi?id=1470634 This patch fixes the problem by hiding the implicit nodes created automatically by the mirror and commit block jobs in the output of query-block and BlockBackend-based query-blockstats as long as the user doesn't indicate that they are aware of those nodes by providing a node name for them in the QMP command to start the block job. The node-based commands query-named-block-nodes and query-blockstats with query-nodes=true still show all nodes, including implicit ones. This ensures that users that are capable of node-level management can still access the full information; users that only know BlockBackends won't use these commands.

|/ | | | | | | | | | | | | | | | Clang 3.9 passes the CONFIG_AVX2_OPT configure test. However, the supplied <cpuid.h> does not contain the bit_AVX2 define that we use when detecting whether the routine can be enabled. Introduce a qemu-specific header that uses the compiler's definition of __cpuid et al, but supplies any missing bit_* definitions needed. This avoids introducing any extra ifdefs to util/bufferiszero.c, and allows quite a few to be removed from tcg/i386/tcg-target.inc.c.

| | | | | | | | | | | | | | | | Solaris 9 was released in 2002, its successor Solaris 10 was released in 2005, and Solaris 9 was end-of-lifed in 2014. Nobody has stepped forward to express interest in supporting Solaris of any flavour, so removing support for the ancient versions seems uncontroversial. In particular, this allows us to remove a use of 'uname' in configure that won't work if you're cross-compiling.
