2014-06-29linux-user: support the KDSIGACCEPT ioctlPaul Burton
Add a definition of the KDSIGACCEPT ioctl & allow its use by target programs. Signed-off-by: Paul Burton <paul@archlinuxmips.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2014-06-29linux-user: allow NULL tv argument for settimeofdayPaul Burton
The tv argument to the settimeofday syscall is allowed to be NULL, if the program only wishes to provide the timezone. QEMU previously returned -EFAULT when tv was NULL. Instead, execute the syscall & provide NULL to the kernel as the target program expected. Signed-off-by: Paul Burton <paul@archlinuxmips.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2014-06-29linux-user: respect timezone for settimeofdayPaul Burton
The settimeofday syscall accepts a tz argument indicating the desired timezone to the kernel. QEMU previously ignored any argument provided by the target program & always passed NULL to the kernel. Instead, translate the argument & pass along the data userland provided. Although this argument is described by the settimeofday man page as obsolete, it is used by systemd as of version 213.

2014-06-29linux-user: support strace of epoll_create1Paul Burton
Add the epoll_create1 syscall to strace.list in order to display that syscall when it occurs, rather than a message about the syscall being unknown despite QEMU already implementing support for it.

2014-06-29linux-user: allow NULL arguments to mountPaul Burton
Calls to the mount syscall can legitimately provide NULL as the value for the source of filesystemtype arguments, which QEMU would previously reject & return -EFAULT to the target program. An example of this is remounting an already mounted filesystem with different properties. Instead of rejecting such syscalls with -EFAULT, pass NULL along to the kernel as the target program expects. Additionally this patch fixes a potential memory leak when DEBUG_REMAP is enabled and lock_user_string fails on the target or filesystemtype arguments but a prior argument was non-NULL and already locked. Since the patch already touched most lines of the TARGET_NR_mount case, it fixes the indentation & coding style for good measure.

2014-06-29linux-user: support SO_PASSSEC setsockopt optionPaul Burton

2014-06-29linux-user: support SO_{SND, RCV}BUFFORCE setsockopt optionsPaul Burton
Translate the SO_SNDBUFFORCE & SO_RCVBUFFORCE options to setsockopt to the host values & perform the syscall as expected, allowing use of those options by target programs. Signed-off-by: Paul Burton <paul@archlinuxmips.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2014-06-29linux-user: translate the result of getsockopt SO_TYPEPaul Burton
QEMU previously passed the result of the host syscall directly to the target program. This is a problem if the host & target have different representations of socket types, as is the case when running a MIPS target program on an x86 host. Introduce a host_to_target_sock_type helper function mirroring the existing target_to_host_sock_type, and call it to translate the value provided by getsockopt when called for the SO_TYPE option.

2014-06-26coroutine-win32.c: Add noinline attribute to work around gcc bugPeter Maydell
A gcc codegen bug in x86_64-w64-mingw32-gcc (GCC) 4.6.3 means that non-debug builds of QEMU for Windows tend to assert when using coroutines. Work around this by marking qemu_coroutine_switch as noinline. If we allow gcc to inline qemu_coroutine_switch into coroutine_trampoline, then it hoists the code to get the address of the TLS variable "current" out of the while() loop. This is an invalid transformation because the SwitchToFiber() call may be called when running thread A but return in thread B, and so we might be in a different thread context each time round the loop. This can happen quite often. Typically. a coroutine is started when a VCPU thread does bdrv_aio_readv: VCPU thread main VCPU thread coroutine I/O coroutine bdrv_aio_readv -----> start I/O operation thread_pool_submit_co <------------ yields back to emulation Then I/O finishes and the thread-pool.c event notifier triggers in the I/O thread. event_notifier_ready calls thread_pool_co_cb, and the I/O coroutine now restarts *in another thread*: iothread main iothread coroutine I/O coroutine (formerly in VCPU thread) event_notifier_ready thread_pool_co_cb -----> current = I/O coroutine; call AIO callback But on Win32, because of the bug, the "current" being set here the current coroutine of the VCPU thread, not the iothread. noinline is a good-enough workaround, and quite unlikely to break in the future. (Thanks to Paolo Bonzini for assistance in diagnosing the problem and providing the detailed example/ascii art quoted above.)

2014-06-25target-i386: Support "invariant tsc" flagMarcelo Tosatti
Expose "Invariant TSC" flag, if KVM is enabled. From Intel documentation: 17.13.1 Invariant TSC The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC. Processor’s support for invariant TSC is indicated by CPUID.80000007H:EDX[8]. The invariant TSC will run at a constant rate in all ACPI P-, C-. and T-states. This is the architectural behavior moving forward. On processors with invariant TSC support, the OS may use the TSC for wall clock timer services (instead of ACPI or HPET timers). TSC reads are much more efficient and do not incur the overhead associated with a ring transition or access to a platform resource.

2014-06-25target-i386: Set migratable=yes by default on "host" CPU mooelEduardo Habkost
Having only migratable flags reported by default on the "host" CPU model is safer for the following reasons: * Existing users may expect "-cpu host" to be migration-safe, if they take care of always using compatible host CPUs, host kernels, and QEMU versions. * Users who don't care aboug migration and want to enable all features supported by the host kernel can simply change their setup to use migratable=no. Without this change, people using "-cpu host" will stop being able to migrate, because now "invtsc" is getting enabled by default. We are not setting migratable=yes by default on all X86CPU subclasses, because users should be able to get non-migratable features enabled if they ask for them explicitly.

2014-06-25target-i386: Add "migratable" property to "host" CPU modelEduardo Habkost
This flag will allow the user to choose between two modes: * All flags that can be enabled on the host, even if unmigratable (migratable=no); * All flags that can be enabled on the host, are known to QEMU and migratable (migratable=yes). The default is still migratable=false, to keep current behavior, but this will be changed to migratable=true by another patch. My plan was to support the "migratable" flag on all CPU classes, but have the default to "false" on all CPU models except "host". However, DeviceClass has no mechanism to allow a child class to have a different property default from the parent class yet, so by now only the "host" CPU model will support the "migratable" flag.

KVM never supported the MONITOR flag so it doesn't make sense to have it enabled by default when KVM is enabled. The rationale here is similar to the cases where it makes sense to have a feature enabled by default on all CPU models when on KVM mode (e.g. x2apic). In this case we are having a feature disabled by default for the same reasons. In this case we don't need machine-type compat code because it is currently impossible to run a KVM VM with the MONITOR flag set.

2014-06-24Add support for the arm breakpoint syscallHunter Laux
