2020-11-23vfio: Make migration support experimentalAlex Williamson3-1/+4
Support for migration of vfio devices is still in flux. Developers are attempting to add support for new devices and new architectures, but none are yet readily available for validation. We have concerns whether we're transferring device resources at the right point in the migration, whether we're guaranteeing that updates during pre-copy are migrated, and whether we can provide bit-stream compatibility should any of this change. Even the question of whether devices should participate in dirty page tracking during pre-copy seems contentious. In short, migration support has not had enough soak time and it feels premature to mark it as supported. Create an experimental option such that we can continue to develop.

2020-11-23gitlab: move remaining x86 check-tcg targets to gitlabAlex Bennée2-26/+17
The GCC check-tcg (user) test in particular was very prone to timing out on Travis. We only actually need to move the some-softmmu builds across as we already have coverage for linux-user. As --enable-debug-tcg does increase the run time somewhat as more debug is put in let's restrict that to just the plugins build. It's unlikely that a plugins enabled build is going to hide a sanity failure in core TCG code so let the plugin builds do the heavy lifting on checking TCG sanity so the non-plugin builds can run swiftly. Now the only remaining check-tcg builds on Travis are for the various non-x86 arches.

It would be nice to keep the ability to remove PCIe and USB from microvm, since thos can be disabled on the command line and therefore should not be included if QEMU is configured --without-default-devices.

2020-11-19trace: use STAP_SDT_V2 to work around symbol visibilityStefan Hajnoczi2-2/+9
QEMU binaries no longer launch successfully with recent SystemTap releases. This is because modular QEMU builds link the sdt semaphores into the main binary instead of into the shared objects where they are used. The symbol visibility of semaphores is 'hidden' and the dynamic linker prints an error during module loading: $ ./configure --enable-trace-backends=dtrace --enable-modules ... ... Failed to open module: /builddir/build/BUILD/qemu-4.2.0/s390x-softmmu/../block-curl.so: undefined symbol: qemu_curl_close_semaphore The long-term solution is to generate per-module dtrace .o files and link them into the module instead of the main binary. In the short term we can define STAP_SDT_V2 so dtrace(1) produces a .o file with 'default' symbol visibility instead of 'hidden'. This workaround is small and easier to merge for QEMU 5.2 and downstream backports.

2020-11-18s390x/pci: fix endianness issuesCornelia Huck4-17/+29
The zPCI group and function structures are big endian. However, we do not consistently store them as big endian locally, and are missing some conversions. Let's just store the structures as host endian instead and convert to big endian when actually handling the instructions retrieving the data. Also fix the layout of ClpReqQueryPciGrp: g is actually only 8 bit. This also fixes accesses on little endian hosts, and makes accesses on big endian hosts consistent.

2020-11-18s390x/pci: Unregister listeners before destroying IOMMU address spaceMatthew Rosato1-0/+7
Hot-unplugging a vfio-pci device on s390x causes a QEMU crash: qemu-system-s390x: ../softmmu/memory.c:2772: do_address_space_destroy: Assertion `QTAILQ_EMPTY(&as->listeners)' failed. In s390, the IOMMU address space is freed during device unplug but the associated vfio-pci device may not yet be finalized and therefore may still have a listener registered to the IOMMU address space. Commit a2166410ad74 ("spapr_pci: Unregister listeners before destroying the IOMMU address space") previously resolved this issue for spapr_pci. We are now seeing this in s390x; it would seem the possibility for this issue was already present but based on a bisect commit 2d24a6466154 ("device-core: use RCU for list of children of a bus") has now changed the timing such that it is now readily reproducible. Add logic to ensure listeners are removed before destroying the address space.

The handler will iterate through each VCPU and dirty the diag318_info reg to be synced with KVM on a subsequent sync_regs call. Additionally, the diag318 info resets must be handled via userspace. As such, QEMU will reset this value for each VCPU during a modified clear, load normal, and load clear reset event.

I'm sending this PR with the blessing of David who is currently on holidays. # gpg: Signature made Wed 18 Nov 2020 10:26:31 GMT # gpg: using RSA key B4828BAF943140CEF2A3491071D4D5E5822F73D6 # gpg: Good signature from "Greg Kurz <groug@kaod.org>" [full] # gpg: aka "Gregory Kurz <gregory.kurz@free.fr>" [full] # gpg: aka "[jpeg image of size 3330]" [full] # Primary key fingerprint: B482 8BAF 9431 40CE F2A3 4910 71D4 D5E5 822F 73D6 * remotes/gkurz/tags/ppc-for-5.2-20201118: Revert series "spapr/xive: Allocate vCPU IPIs from the vCPU contexts" Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2020-11-18authz-list-file: Fix file read error handlingMarkus Armbruster1-0/+3
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. qauthz_list_file_complete() is wrong that way: it passes @errp to qauthz_list_file_complete() without checking for failure. If it runs into another failure, it trips error_setv()'s assertion. Reproducer: $ qemu-system-x86_64 -nodefaults -S -display none -object authz-list-file,id=authz0,filename= qemu-system-x86_64: ../util/error.c:59: error_setv: Assertion `*errp == NULL' failed.

2020-11-18Revert series "spapr/xive: Allocate vCPU IPIs from the vCPU contexts"Greg Kurz1-84/+18
This series was largely built on the assumption that IPI numbers are numerically equal to vCPU ids. Even if this happens to be the case in practice with the default machine settings, this ceases to be true if VSMT is set to a different value than the number of vCPUs per core. This causes bogus IPI numbers to be created in KVM from a guest stand point. This leads to unknow results in the guest, including crashes or missing vCPUs (see BugLink) and even non-fatal oopses in current KVM that lacks a check before accessing misconfigured HW (see [1]). A tentative patch was sent (see [2]) but it seems too complex to be merged in an RC. Since the original changes are essentially an optimization, it seems safer to revert them for now. The damage is done by commit acbdb9956fe9 ("spapr/xive: Allocate IPIs independently from the other sources") but the previous patches in the series are really preparatory patches. So this reverts the whole series: eab0a2d06e97 ("spapr/xive: Allocate vCPU IPIs from the vCPU contexts") acbdb9956fe9 ("spapr/xive: Allocate IPIs independently from the other sources") fa94447a2cd6 ("spapr/xive: Use kvmppc_xive_source_reset() in post_load") 235d3b116213 ("spapr/xive: Modify kvm_cpu_is_enabled() interface") [1] https://marc.info/?l=kvm-ppc&m=160458409722959&w=4 [2] https://lists.gnu.org/archive/html/qemu-devel/2020-11/msg03626.html Reported-by: Satheesh Rajendran <sathnaga@linux.vnet.ibm.com> Fixes: acbdb9956fe9 ("spapr/xive: Allocate IPIs independently from the other sources") BugLink: https://bugs.launchpad.net/qemu/+bug/1900241 Signed-off-by: Greg Kurz <groug@kaod.org> Acked-by: Cédric Le Goater <clg@kaod.org> Message-Id: <160554086275.1325084.12110142252189044646.stgit@bahia.lan>

2020-11-17json: Fix a memleak in parse_pair()Alex Chen2-6/+15
In qobject_type(), NULL is returned when the 'QObject' returned from parse_value() is not of QString type, and this 'QObject' memory will leaked. So we need to first cache the 'QObject' returned from parse_value(), and finally free 'QObject' memory at the end of the function. Also, we add a testcast about invalid dict key. The memleak stack is as follows: Direct leak of 32 byte(s) in 1 object(s) allocated from: #0 0xfffe4b3c34fb in __interceptor_malloc (/lib64/libasan.so.4+0xd34fb) #1 0xfffe4ae48aa3 in g_malloc (/lib64/libglib-2.0.so.0+0x58aa3) #2 0xaaab3557d9f7 in qnum_from_int qemu/qobject/qnum.c:25 #3 0xaaab35584d23 in parse_literal qemu/qobject/json-parser.c:511 #4 0xaaab35584d23 in parse_value qemu/qobject/json-parser.c:554 #5 0xaaab35583d77 in parse_pair qemu/qobject/json-parser.c:270 #6 0xaaab355845db in parse_object qemu/qobject/json-parser.c:327 #7 0xaaab355845db in parse_value qemu/qobject/json-parser.c:546 #8 0xaaab35585b1b in json_parser_parse qemu/qobject/json-parser.c:580 #9 0xaaab35583703 in json_message_process_token qemu/qobject/json-streamer.c:92 #10 0xaaab355ddccf in json_lexer_feed_char qemu/qobject/json-lexer.c:313 #11 0xaaab355de0eb in json_lexer_feed qemu/qobject/json-lexer.c:350 #12 0xaaab354aff67 in tcp_chr_read qemu/chardev/char-socket.c:525 #13 0xfffe4ae429db in g_main_context_dispatch (/lib64/libglib-2.0.so.0+0x529db) #14 0xfffe4ae42d8f (/lib64/libglib-2.0.so.0+0x52d8f) #15 0xfffe4ae430df in g_main_loop_run (/lib64/libglib-2.0.so.0+0x530df) #16 0xaaab34d70bff in iothread_run qemu/iothread.c:82 #17 0xaaab3559d71b in qemu_thread_start qemu/util/qemu-thread-posix.c:519 Fixes: 532fb5328473 ("qapi: Make more of qobject_to()") Reported-by: Euler Robot <euler.robot@huawei.com> Signed-off-by: Alex Chen <alex.chen@huawei.com> Signed-off-by: Chen Qun <kuhn.chenqun@huawei.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20201113145525.85151-1-alex.chen@huawei.com> [Commit message tweaked]
