* log: Make glib logging go through QEMUChristophe Fergeau2019-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a error_init() helper which calls g_log_set_default_handler() so that glib logs (g_log, g_warning, ...) are handled similarly to other QEMU logs. This means they will get a timestamp if timestamps are enabled, and they will go through the HMP monitor if one is configured. This commit also adds a call to error_init() to the binaries installed by QEMU. Since error_init() also calls error_set_progname(), this means that *-linux-user, *-bsd-user and qemu-pr-helper messages output with error_report, info_report, ... will slightly change: they will be prefixed by the binary name. glib debug messages are enabled through G_MESSAGES_DEBUG similarly to the glib default log handler. At the moment, this change will mostly impact SPICE logging if your spice version is >= 0.14.1. With older spice versions, this is not going to work as expected, but will not have any ill effect, so this call is not conditional on the SPICE version.

| | | | | | | | | | | | | | | | | | | | Some versions of Clang prior to 6.0 (and some builds of clang after, such as 6.0.1-2.fc28) fail to recognize { 0 } as a valid initializer for a struct with subobjects when -Wmissing-braces is enabled. https://bugs.llvm.org/show_bug.cgi?id=21689 and https://reviews.llvm.org/rL314499 suggests this should be fixed in 6.0, but it might not be the case for older versions or downstream versions. For now, follow the precedent of ebf2a499 and replace the standard { 0 } with the accepted { } to silence this warning and allow the build to work under clang 6.0.1-2.fc28, and builds prior to 6.0.

* util: add qemu_write_pidfile()Marc-André Lureau2018-10-021-35/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are variants of qemu_create_pidfile() in qemu-pr-helper and qemu-ga. Let's have a common implementation in libqemuutil. The code is initially based from pr-helper write_pidfile(), with various improvements and suggestions from Daniel Berrangé: QEMU will leave the pidfile existing on disk when it exits which initially made me think it avoids the deletion race. The app managing QEMU, however, may well delete the pidfile after it has seen QEMU exit, and even if the app locks the pidfile before deleting it, there is still a race. eg consider the following sequence QEMU 1 libvirtd QEMU 2 1. lock(pidfile) 2. exit() 3. open(pidfile) 4. lock(pidfile) 5. open(pidfile) 6. unlink(pidfile) 7. close(pidfile) 8. lock(pidfile) IOW, at step 8 the new QEMU has successfully acquired the lock, but the pidfile no longer exists on disk because it was deleted after the original QEMU exited. While we could just say no external app should ever delete the pidfile, I don't think that is satisfactory as people don't read docs, and admins don't like stale pidfiles being left around on disk. To make this robust, I think we might want to copy libvirt's approach to pidfile acquisition which runs in a loop and checks that the file on disk /after/ acquiring the lock matches the file that was locked. Then we could in fact safely let QEMU delete its own pidfiles on clean exit..

This fixes that by probing the new libmultipath API in configure. If it fails, then try probing the old API. If it fails, then consider libmultipath not available.

* pr-helper: avoid error on PR IN command with zero request sizePaolo Bonzini2018-07-061-33/+30Star
| | | | | | | | | | | | | | | | | | | | | | After reading a PR IN command with zero request size in prh_read_request, the resp->result field will be uninitialized and the resp.sz field will be also uninitialized when returning to prh_co_entry. If resp->result == GOOD (from a previous successful reply or just luck), then the assert in prh_write_response might not be triggered and uninitialized response will be sent. The fix is to remove the whole handling of sz == 0 in prh_co_entry. Those errors apply only to PR OUT commands and it's perfectly okay to catch them later in do_pr_out and multipath_pr_out; the check for too-short parameters in fact doesn't apply in the easy SG_IO case, as it can be left to the target firmware even. The result is that prh_read_request does not fail requests anymore and prh_co_entry becomes simpler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 67a1de0d195a there is no space anymore between the version number and the parentheses when running configure with --with-pkgversion=foo : $ qemu-system-s390x --version QEMU emulator version 2.11.50(foo) But the space is included when building without that option when building from a git checkout: $ qemu-system-s390x --version QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty) The same confusion exists with the "query-version" QMP command. Let's fix this by introducing a proper QEMU_FULL_VERSION definition that includes the space and parentheses, while the QEMU_PKGVERSION should just cleanly contain the package version string itself. Note that this also changes the behavior of the "query-version" QMP command (the space and parentheses are not included there anymore), but that's supposed to be OK since the strings there are not meant to be parsed by other tools.

* scsi, file-posix: add support for persistent reservation managementPaolo Bonzini2017-09-223-0/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is a common requirement for virtual machine to send persistent reservations, but this currently requires either running QEMU with CAP_SYS_RAWIO, or using out-of-tree patches that let an unprivileged QEMU bypass Linux's filter on SG_IO commands. As an alternative mechanism, the next patches will introduce a privileged helper to run persistent reservation commands without expanding QEMU's attack surface unnecessarily. The helper is invoked through a "pr-manager" QOM object, to which file-posix.c passes SG_IO requests for PERSISTENT RESERVE OUT and PERSISTENT RESERVE IN commands. For example: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -drive if=none,id=hd,driver=raw,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd or: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -blockdev node-name=hd,driver=raw,file.driver=host_device,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd Multiple pr-manager implementations are conceivable and possible, though only one is implemented right now. For example, a pr-manager could: - talk directly to the multipath daemon from a privileged QEMU (i.e. QEMU links to libmpathpersist); this makes reservation work properly with multipath, but still requires CAP_SYS_RAWIO - use the Linux IOC_PR_* ioctls (they require CAP_SYS_ADMIN though) - more interestingly, implement reservations directly in QEMU through file system locks or a shared database (e.g. sqlite) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
