2017-09-21nvic: Add cached vectpending_prio statePeter Maydell1-0/+2
Instead of looking up the pending priority in nvic_pending_prio(), cache it in a new state struct field. The calculation of the pending priority given the interrupt number is more complicated in v8M with the security extension, so the caching will be worthwhile. This changes nvic_pending_prio() from returning a full (group + subpriority) priority value to returning a group priority. This doesn't require changes to its callsites because we use it only in comparisons of the form execution_prio > nvic_pending_prio() and execution priority is always a group priority, so a test (exec prio > full prio) is true if and only if (execprio > group_prio). (Architecturally the expected comparison is with the group priority for this sort of "would we preempt" test; we were only doing a test with a full priority as an optimisation to avoid the mask, which is possible precisely because the two comparisons always give the same answer.)

2017-09-19numa: cpu: calculate/set default node-ids after all -numa CLI options are parsedIgor Mammedov1-0/+4
Calculating default node-ids for CPUs in possible_cpu_arch_ids() is rather fragile since defaults calculation uses nb_numa_nodes but callback might be potentially called early before all -numa CLI options are parsed, which would lead to cpus assigned only upto nb_numa_nodes at the time possible_cpu_arch_ids() is called. Issue was introduced by (7c88e65 numa: mirror cpu to node mapping in MachineState::possible_cpus) and for example CLI: -smp 4 -numa node,cpus=0 -numa node would set props.node-id in possible_cpus array for every non explicitly mapped CPU to the first node. Issue is not visible to guest nor to mgmt interface due to 1) implictly mapped cpus are forced to the first node in case of partial mapping 2) in case of default mapping possible_cpu_arch_ids() is called after all -numa options are parsed (resulting in correct mapping). However it's fragile to rely on late execution of possible_cpu_arch_ids(), therefore add machine specific callback that returns node-id for CPU and use it to calculate/ set defaults at machine_numa_finish_init() time when all -numa options are parsed.

2017-09-19osdep.h: Prohibit disabling assert() in supported buildsEric Blake1-0/+16
We already have several files that knowingly require assert() to work, sometimes because refactoring the code for proper error handling has not been tackled yet; there are probably other files that have a similar situation but with no comments documenting the same. In fact, we have places in migration that handle untrusted input with assertions, where disabling the assertions risks a worse security hole than the current behavior of losing the guest to SIGABRT when migration fails because of the assertion. Promote our current per-file safety-valve to instead be project-wide, and expand it to also cover glib's g_assert(). Note that we do NOT want to encourage 'assert(side-effects);' (that is a bad practice that prevents copy-and-paste of code to other projects that CAN disable assertions; plus it costs unnecessary reviewer mental cycles to remember whether a project special-cases the crippling of asserts); and we would LIKE to fix migration to not rely on asserts (but that takes a big code audit). But in the meantime, we DO want to send a message that anyone that disables assertions has to tweak code in order to compile, making it obvious that they are taking on additional risk that we are not going to support. At the same time, leave comments mentioning NDEBUG in files that we know still need to be scrubbed, so there is at least something to grep for. It would be possible to come up with some other mechanism for doing runtime checking by default, but which does not abort the program on failure, while leaving side effects in place (unlike how crippling assert() avoids even the side effects), perhaps under the name q_verify(); but it was not deemed worth the effort (developers should not have to learn a replacement when the standard C macro works just fine, and it would be a lot of churn for little gain). The patch specifically uses #error rather than #warn so that a user is forced to tweak the header to acknowledge the issue, even when not using a -Werror compilation.

2017-09-19arm: drop intermediate cpu_model -> cpu type parsing and use cpu type directlyIgor Mammedov3-4/+4
there are 2 use cases to deal with: 1: fixed CPU models per board/soc 2: boards with user configurable cpu_model and fallback to default cpu_model if user hasn't specified one explicitly For the 1st drop intermediate cpu_model parsing and use const cpu type directly, which replaces: typename = object_class_get_name( cpu_class_by_name(TYPE_ARM_CPU, cpu_model)) object_new(typename) with object_new(FOO_CPU_TYPE_NAME) or cpu_generic_init(BASE_CPU_TYPE, "my cpu model") with cpu_create(FOO_CPU_TYPE_NAME) as result 1st use case doesn't have to invoke not necessary translation and not needed code is removed. For the 2nd 1: set default cpu type with MachineClass::default_cpu_type and 2: use generic cpu_model parsing that done before machine_init() is run and: 2.1: drop custom cpu_model parsing where pattern is: typename = object_class_get_name( cpu_class_by_name(TYPE_ARM_CPU, cpu_model)) [parse_features(typename, cpu_model, &err) ] 2.2: or replace cpu_generic_init() which does what 2.1 does + create_cpu(typename) with just create_cpu(machine->cpu_type) as result cpu_name -> cpu_type translation is done using generic machine code one including parsing optional features if supported/present (removes a bunch of duplicated cpu_model parsing code) and default cpu type is defined in an uniform way within machine_class_init callbacks instead of adhoc places in boadr's machine_init code.

2017-09-19vl.c: convert cpu_model to cpu type and set of global properties before ↵Igor Mammedov1-0/+6
machine_init() All machines that support user specified cpu_model either call cpu_generic_init() or cpu_class_by_name()/CPUClass::parse_features to parse feature string and to get CPU type to create. Which leads to code duplication and hard-codding default CPU model within machine_foo_init() code. Which makes it impossible to get CPU type before machine_init() is run. So instead of setting default CPUs models and doing parsing in target specific machine_foo_init() in various ways, provide a generic data driven cpu_model parsing before machine_init() is called. in follow up per target patches, it will allow to: * define default CPU type in consistent/generic manner per machine type and drop custom code that fallbacks to default if cpu_model is NULL * drop custom features parsing in targets and do it in centralized way. * for cases of cpu_generic_init(TYPE_BASE/DEFAULT_CPU, "some_cpu") replace it with cpu_create(machine->cpu_type) || cpu_create(TYPE_FOO) depending if CPU type is user settable or not. not doing useless parsing and clearly documenting where CPU model is user settable or fixed one. Patch allows machine subclasses to define default CPU type per machine class at class_init() time and if that is set generic code will parse cpu_model into a MachineState::cpu_type which will be used to create CPUs for that machine instance and allows gradual per board conversion.

This commit allows you to choose the virtqueue size for each virtio-scsi-pci controller like this: -device virtio-scsi-pci,id=scsi,virtqueue_size=16 The default is still 128 as before. Using smaller virtqueue_size allows many more disks to be added to small memory virtual machines.

2017-09-15seccomp: add resourcecontrol argument to command lineEduardo Otubo1-0/+1
This patch adds [,resourcecontrol=deny] to `-sandbox on' option. It blacklists all process affinity and scheduler priority system calls to avoid any bigger of the process. Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2017-09-15seccomp: add spawn argument to command lineEduardo Otubo1-0/+1
This patch adds [,spawn=deny] argument to `-sandbox on' option. It blacklists fork and execve system calls, avoiding Qemu to spawn new threads or processes. Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2017-09-15seccomp: add elevateprivileges argument to command lineEduardo Otubo1-0/+1
This patch introduces the new argument [,elevateprivileges=allow|deny|children] to the `-sandbox on'. It allows or denies Qemu process to elevate its privileges by blacklisting all set*uid|gid system calls. The 'children' option will let forks and execves run unprivileged. Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2017-09-15seccomp: add obsolete argument to command lineEduardo Otubo1-1/+2
This patch introduces the argument [,obsolete=allow] to the `-sandbox on' option. It allows Qemu to run safely on old system that still relies on old system calls. Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2017-09-15seccomp: changing from whitelist to blacklistEduardo Otubo1-0/+2
This patch changes the default behavior of the seccomp filter from whitelist to blacklist. By default now all system calls are allowed and a small black list of definitely forbidden ones was created. Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2017-09-15ppc/xive: fix OV5_XIVE_EXPLOIT bitsCédric Le Goater1-1/+2
On POWER9, the Client Architecture Support (CAS) negotiation process determines whether the guest operates in XIVE Legacy compatibility or in XIVE exploitation mode. Now that we have initial guest support for the XIVE interrupt controller, let's fix the bits definition which have evolved in the latest specs. The platform advertises the XIVE Exploitation Mode support using the property "ibm,arch-vec-5-platform-support-vec-5", byte 23 bits 0-1 : - 0b00 XIVE legacy mode Only - 0b01 XIVE exploitation mode Only - 0b10 XIVE legacy or exploitation mode The OS asks for XIVE Exploitation Mode support using the property "ibm,architecture-vec-5", byte 23 bits 0-1: - 0b00 XIVE legacy mode Only - 0b01 XIVE exploitation mode Only Signed-off-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-09-15net: Add SunGEM device emulation as found on Apple UniNorthBenjamin Herrenschmidt1-0/+1
This adds a simplistic emulation of the Sun GEM ethernet controller found in Apple ASICs. Currently we only support the Apple UniNorth 1.x variant, but the other Apple or Sun variants should mostly be a matter of adding PCI IDs options. We have a very primitive emulation of a single Broadcom 5201 PHY which is supported by the MacOS driver. This model brings out-of-the-box networking to MacOS 9, and all versions of OS X I tried with the mac99 platform. Further improvements from Mark: - Remove sungem.h file, moving constants into sungem.c as required - Switch to using tracepoints for debugging - Split register blocks into separate memory regions - Use arrays in SunGEMState to hold register values - Add state-saving support Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

Add a machine level virtualization property. This defaults to false and can be set to true using this machine command line argument: -machine xlnx-zcu102,virtualization=on This follows what the ARM virt machine does.
