2016-03-15virtio-9p: use accessor to get thread_poolGreg Kurz1-1/+1
The aio_context_new() function does not allocate a thread pool. This is deferred to the first call to the aio_get_thread_pool() accessor. It is hence forbidden to access the thread_pool field directly, as it may be NULL. The accessor *must* be used always.

2016-03-15configure: Fix shell syntax to placate OpenBSD's pdkshPeter Maydell1-1/+5
Unfortunately the OpenBSD pdksh does not like brackets inside the right part of a ${variable+word} parameter expansion: $ echo "${a+($b)}" ksh: ${a+($b)}": bad substitution though both bash and dash accept them. In any case this line was causing odd output in the case where nettle is not present: nettle no () (because if nettle is not present then $nettle will be "no", not a null string or unset).

2016-03-15target-ppc: kvm: fix floating point registers sync on little-endian hostsGreg Kurz1-0/+12
On VSX capable CPUs, the 32 FP registers are mapped to the high-bits of the 32 first VSX registers. So if you have: VSR31 = (uint128) 0x0102030405060708090a0b0c0d0e0f00 then FPR31 = (uint64) 0x0102030405060708 The kernel stores the VSX registers in the fp_state struct following the host endian element ordering. On big-endian: fp_state.fpr[31][0] = 0x0102030405060708 fp_state.fpr[31][1] = 0x090a0b0c0d0e0f00 On little-endian: fp_state.fpr[31][0] = 0x090a0b0c0d0e0f00 fp_state.fpr[31][1] = 0x0102030405060708 The KVM_GET_ONE_REG and KVM_SET_ONE_REG ioctls preserve this ordering, but QEMU considers it as big-endian and always copies element [0] to the fpr[] array and element [1] to the vsr[] array. This does not work with little-endian hosts, and you will get: (qemu) p $f31 0x90a0b0c0d0e0f00 instead of: (qemu) p $f31 0x102030405060708 This patch fixes the element ordering for little-endian hosts.

2015-12-11blockdev: Mark {insert, remove}-medium experimentalMax Reitz5-33/+45
While in the long term we want throttling to be its own block filter BDS, in the short term we want it to be part of the BB instead of a BDS; even in the long term we may want legacy throttling to be automatically tied to the BB. blockdev-insert-medium and blockdev-remove-medium do not retain throttling information in the BB (deliberately so). Therefore, using them means tying this information to a BDS, which would break the model described above. (The same applies to other flags such as detect_zeroes.) We probably want to move this information to the BB or its own filter BDS before blockdev-{insert,remove}-medium can be considered completely stable. Therefore, mark these functions experimental for the time being.

2015-12-11Fix xbzrle vs last_sent_block updateDr. David Alan Gilbert1-1/+10
My fix (84e7b80a) replaced the last_sent_block update that I'd removed earlier; however it was too aggressive in the xbzrle case. save_xbzrle_page might return '0' to mean that the page didn't need sending since it was the same as the last sent version; in this case we can't update 'last_sent_block' since we didn't actually send it. Symptom: 'Illegal RAM offset 1018000' as we try and send a page to the wrong RAMBlock; potentially that could be a data corruption if you were really unlucky.

2015-12-10virtio-9p-device: add minimal unrealize handlerGreg Kurz1-0/+12
Since commit 4652f1640e029e1f2433fa77ba6af285 "virtio-9p: add savevm handlers", if the user hot-unplugs a quiescent 9p device and live migrates, the source QEMU crashes before migration completetion... This happens because virtio-9p devices have a realize handler which calls virtio_init() and register_savevm(). Both calls store pointers to the device internals, that get dereferenced during migration even if the device got unplugged. This patch simply adds an unrealize handler to perform minimal cleanup and avoid the crash. Hot unplug of non-quiescent 9p devices is still not supported in QEMU, and not supported by linux guests either. Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Reviewed-by: Michael S.

blk_attach_dev() fails here only when we're working for device "sdhci-pci" (which already attached the backend), and then we don't want to attach a second time. If we ever create another failure mode, we're setting up ourselves to using the same backend from multiple frontends, which is likely to end in tears.

We currently fuse controller and card into a single device model, but we intend qomify things properly and separate the two. The properties that really belong to the card would then have to somehow pass-through to the card's properties. To avoid that complication, either mark them experimental or drop them. Properties "capareg", "maxcurr" and the usual PCI device properties belong to the controller. Property "drive" belongs to the card; rename it to "x-drive". Properties "logical_block_size", "physical_block_size", "min_io_size", "opt_io_size", "discard_granularity" belong to the card, but have no effect; drop them.

2015-12-07e1000: fix hang of win2k12 shutdown with flood pingDenis V. Lunev1-0/+5
e1000 driver in Win2k12 is really well rotten. It 100% hangs on shutdown of UP VM under flood ping. The guest checks card state and reinjects itself interrupt in a loop. This is fatal for UP machine. There is no good way to fix this misbehavior but to kludge it. The emulation has interrupt throttling register aka ITR which limits interrupt rate and allows the guest to proceed this phase. There is no problem with this kludge for Linux guests - it adjust the value of it itself. On the other hand according to the initial research in commit e9845f0985f088dd01790f4821026df0afba5795 Author: Vincenzo Maffione <v.maffione@gmail.com> Date: Fri Aug 2 18:30:52 2013 +0200 e1000: add interrupt mitigation support ...

We have several function parameters declared as void (*fn). This is just a stupid way to write void *, and the only purpose writing it like that could serve is obscuring the sin of bypassing the type system without need. The original sin is commit 49ee359: its qtest_add_func() is a wrapper for g_test_add_func(). Fix the parameter type to match g_test_add_func()'s. This uncovers type errors in ide-test.c; fix them. Commit 7949c0e faithfully repeated the sin for qtest_add_data_func(). Fix it the same way, along with a harmless type error uncovered in vhost-user-test.c. Commit 063c23d repeated it for qtest_add_abrt_handler(). The screwy parameter gets assigned to GHook member func, so change its type to match. Requires wrapping kill_qemu() to keep the type checker happy.

2015-12-04gt64xxx: fix decoding of ISD registerPaolo Bonzini1-1/+2
The GT64xxx's internal registers can be placed above the first 4 GiB in the address space, but not above the first 64 GiB. Correctly cast the register to a 64-bit integer, and mask away bits above bit 35. Datasheet at http://pdf.datasheetarchive.com/datasheetsmain/Datasheets-33/DSA-655889.pdf (bug reported by Coverity).

2015-12-04configure: use appropriate code fragment for -fstack-protector checksRodrigo Rebello1-0/+10
The check for stack-protector support consisted in compiling and linking the test program below (output by function write_c_skeleton()) with the compiler flag -fstack-protector-strong first and then with -fstack-protector-all if the first one failed to work: int main(void) { return 0; } This caused false positives when using certain toolchains in which the compiler accepted -fstack-protector-strong but no support was provided by the C library, since for this stack-protector variant the compiler emits canary code only for functions that meet specific conditions (local arrays, memory references to local variables, etc.) and the code fragment under test included none of them (hence no stack protection code generated, no link failure). This fix changes the test program used for -fstack-protector checks to include a function that meets conditions which cause the compiler to generate canary code in all variants.

2015-12-04crypto: avoid two coverity false positive error reportsDaniel P. Berrange2-2/+3
In qcrypto_tls_creds_get_path() coverity complains that we are checking '*creds' for NULL, despite having dereferenced it previously. This is harmless bug due to fact that the trace call was too early. Moving it after the cleanup gets the desired semantics. In qcrypto_tls_creds_check_cert_key_purpose() coverity complains that we're passing a pointer to a previously free'd buffer into gnutls_x509_crt_get_key_purpose_oid() This is harmless because we're passing a size == 0, so gnutls won't access the buffer, but rather just report what size it needs to be. We can avoid it though by explicitly setting the buffer to NULL after free'ing it. Signed-off-by: Daniel P.

2015-12-04configure: Diagnose broken linkers directlyPeter Maydell1-0/+3
Currently if the user's compiler works for creating .o files but their linker is broken such that compiling an executable from a C file does not work, we will report a misleading error message about the compiler not supporting __thread (since that happens to be the first test we run which requires a working linker). Explicitly check that compile_prog works as well as compile_object, so that people whose toolchain setup is broken get a more helpful error message.

2015-12-04spapr_drc: Change value of property "fdt" from null back to {}Markus Armbruster1-0/+5
prop_get_fdt() misuses the visitor API: when fdt is null, it doesn't visit anything. object_property_get_qobject() happily object_property_get_qobject(). Amazingly, the latter survives the misuse. Turns out we've papered over it long before prop_get_fdt() existed, in commit 1d10b44. However, commit 6c2f9a1 changed how we paper over it, and as a side effect changed qom-get's value from {} to null. Change it right back by fixing the visitor misuse.
