2017-10-23configure: disable qemu-keymap for linux-user qemuLaurent Vivier
We don't need qemu-keymap when we build only linux-user qemu. When we compile in static mode, the libxkbcommon is detected by configure if the shared one is available, but cannot be linked if the static version is not available. As we don't need it for qemu-linux-user, and we generally need a static link to use it in a chroot, disable qemu-keymap in this case.

2017-10-18qemu-pr-helper: use new libmultipath APIPaolo Bonzini
libmultipath has recently changed its API. The new API supports multi-threaded clients better. Unfortunately there is no backwards-compatibility, so we just switch to the new one. Running QEMU compiled with the new library on the old library will likely crash, while doing the opposite will cause QEMU not to start at all (because udev, get_multipath_config and put_multipath_config are undefined).

The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a data file mapping between all the different scancode/keycode/keysym sets that are known, and a tool to auto-generate lookup tables for different combinations. It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys. Using it in QEMU will let us replace many hand written lookup tables with auto-generated tables from a master data source, reducing bugs. Adding new QKeyCodes will now only require the master table to be updated, all ~20 other tables will be automatically updated to follow. Signed-off-by: Daniel P.

2017-10-16build: automatically handle GIT submodule checkout for dtcDaniel P. Berrange
Currently if DTC is required by configure and not available in the host OS install, we exit with an error message telling the user to checkout a git submodule or install the library. This introduces automatic handling of the git submodule checkout process and enables it for dtc. This only runs if building from GIT, so users of release tarballs still need the system library install. The current state of the git checkout is stashed in .git-submodule-status, and a helper program is used to determine if this state matches the desired submodule state. A dependency against 'Makefile' ensures that the submodule state is refreshed at the start of the build process Signed-off-by: Daniel P.

2017-10-13tpm: Added support for TPM emulatorAmarnath Valluri
This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel. The swtpm and associated tools can be found here: https://github.com/stefanberger/swtpm The swtpm's control channel protocol specification can be found here: https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification Usage: # setup TPM state directory mkdir /tmp/mytpm chown -R tss:root /tmp/mytpm /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek # Ask qemu to use TPM emulator with given tpm state directory qemu-system-x86_64 \ [...] \ -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis,tpmdev=tpm0 \ [...] Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

Add a firmware path config option to configure. Multiple directories are accepted, with the usual colon as separator. Default value is ${prefix}/share/qemu-firmware. The path is searched in addition to the current search path (typically ${prefix}/share/qemu). This prepares qemu for the planned split of the prebuilt firmware blobs into a separate project.

2017-09-26util/qemu-thread-posix.c: Replace OS ifdefs with CONFIG_HAVE_SEM_TIMEDWAITPeter Maydell
In qemu-thread-posix.c we have two implementations of the various qemu_sem_* functions, one of which uses native POSIX sem_* and the other of which emulates them with pthread conditions. This is necessary because not all our host OSes support sem_timedwait(). Instead of a hard-coded list of OSes which don't implement sem_timedwait(), which gets out of date, make configure test for the presence of the function and set a new CONFIG_HAVE_SEM_TIMEDWAIT appropriately. In particular, newer NetBSDs have sem_timedwait(), so this commit will switch them over to using it. OSX still does not have an implementation.

2017-09-22scsi: add multipath support to qemu-pr-helperPaolo Bonzini
Proper support of persistent reservation for multipath devices requires communication with the multipath daemon, so that the reservation is registered and applied when a path comes up. The device mapper utilities provide a library to do so; this patch makes qemu-pr-helper.c detect multipath devices and, when one is found, delegate the operation to libmpathpersist. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-09-22scsi: build qemu-pr-helperPaolo Bonzini
Introduce a privileged helper to run persistent reservation commands. This lets virtual machines send persistent reservations without using CAP_SYS_RAWIO or out-of-tree patches. The helper uses Unix permissions and SCM_RIGHTS to restrict access to processes that can access its socket and prove that they have an open file descriptor for a raw SCSI device. The next patch will also correct the usage of persistent reservations with multipath devices. It would also be possible to support for Linux's IOC_PR_* ioctls in the future, to support NVMe devices. For now, however, only SCSI is supported. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-08-30configure: enable --s390-pgste linker optionChristian Borntraeger
KVM guests on s390 need a different page table layout than normal processes (2kb page table + 2kb page status extensions vs 2kb page table only). As of today this has to be enabled via the vm.allocate_pgste sysctl. Newer kernels (>= 4.12) on s390 check for an S390_PGSTE program header and enable the pgste page table extensions in that case. This makes the vm.allocate_pgste sysctl unnecessary. We enable this program header for the s390 system emulation (qemu-system-s390x) if we build on s390 - for s390 system emulation - the linker supports --s390-pgste (binutils >= 2.29) - KVM is enabled This will allow distributions to disable the global vm.allocate_pgste sysctl, which will improve the page table allocation for non KVM processes as only 2kb chunks are necessary.

2017-07-21configure: Never use 'uname' to identify target OSPeter Maydell
For a very long time we have used 'uname -s' as our fallback if we don't identify the target OS using a compiler #define. This obviously doesn't work for cross-compilation, and we've had a comment suggesting we fix this in configure for a long time. Since we now have an exhaustive list of which OSes we can run on (thanks to commit 898be3e0415 making an unrecognized OS be a fatal error), we know which ones we're missing. Add check_define tests for the remaining OSes we support. The defines checked are based on ones we already use in the codebase for identifying the host OS (with the exception of GNU/kFreeBSD). We can now set bogus_os immediately rather than doing it later. We leave the comment about uname being bad untouched, since there is still a use of it for the fallback for unrecognized host CPU type.

2017-07-20configure: Don't build ivshmem tools unless CONFIG_IVSHMEM is setKamil Rytarowski
Don't try to build the ivshmem-server and ivshmem-client tools unless CONFIG_IVSHMEM is set. This fixes in passing a build bug on NetBSD, which fails to build the ivshmem tools because they use shm_open() and on NetBSD that requires linking against -lrt.

2017-07-18xen/mapcache: introduce xen_replace_cache_entry()Igor Druzhinin
This new call is trying to update a requested map cache entry according to the changes in the physmap. The call is searching for the entry, unmaps it and maps again at the same place using a new guest address. If the mapping is dummy this call will make it real. This function makes use of a new xenforeignmemory_map2() call with an extended interface that was recently introduced in libxenforeignmemory [1].
