2018-06-04linux-user: SPARC "rd %tick" can be used by user applicationLaurent Vivier1-1/+3
we have the same problem decribed in 7d6b1daedd ("linux-user, ppc: mftbl can be used by user application") for ppc in the case of sparc. When we use an application trying to resolve a name, it hangs in 0x00000000ff5dd40c: rd %tick, %o5 0x00000000ff5dd410: srlx %o5, 0x20, %o4 0x00000000ff5dd414: btst %o5, %g4 0x00000000ff5dd418: be %icc, 0xff5dd40c because %tick is staying at 0.

If CONFIG_SECCOMP is undefined, the option 'elevatedprivileges' remains compiled. This would make libvirt set the corresponding capability and then trigger failure during guest startup. This patch moves the code regarding seccomp command line options to qemu-seccomp.c file and wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP.

When setting up an outgoing user mode networking TCP connection, disable the Nagle algorithm in the host-side connection. Either the guest is already doing Nagle, in which case there is no point in doing it twice, or it has chosen to disable it, in which case we should respect that choice. This change speeds up GDB remote debugging over TCP over user mode networking (with GDB runing on the guest) by multiple orders of magnitude, and has been part of the local patches applied by pkgsrc since 2012 with no reported ill effects.

2018-05-31xen-hvm: stop faking I/O to access PCI config spacePaul Durrant2-20/+84
This patch removes the current hackery where IOREQ_TYPE_PCI_CONFIG requests are handled by faking PIO to 0xcf8 and 0xcfc and replaces it with direct calls to pci_host_config_read/write_common(). Doing so necessitates mapping BDFs to PCIDevices but maintaining a simple QLIST in xen_device_realize/unrealize() will suffice. NOTE: whilst config space accesses are currently limited to PCI_CONFIG_SPACE_SIZE, this patch paves the way to increasing the limit to PCIE_CONFIG_SPACE_SIZE when Xen gains the ability to emulate MCFG table accesses.

2018-05-31Make MemoryRegion valid.accepts callback take a MemTxAttrs argumentPeter Maydell7-13/+25
As part of plumbing MemTxAttrs down to the IOMMU translate method, add MemTxAttrs as an argument to the MemoryRegion valid.accepts callback. We'll need this for subpage_accepts(). We could take the approach we used with the read and write callbacks and add new a new _with_attrs version, but since there are so few implementations of the accepts hook we just change them all.

2018-05-31Make memory_region_access_valid() take a MemTxAttrs argumentPeter Maydell4-6/+11
As part of plumbing MemTxAttrs down to the IOMMU translate method, add MemTxAttrs as an argument to memory_region_access_valid(). Its callers either have an attrs value to hand, or don't care and can use MEMTXATTRS_UNSPECIFIED. The callsite in flatview_access_valid() is part of a recursive loop flatview_access_valid() -> memory_region_access_valid() -> subpage_accepts() -> flatview_access_valid(); we make it pass MEMTXATTRS_UNSPECIFIED for now, until the next several commits have plumbed an attrs parameter through the rest of the loop and we can add an attrs parameter to flatview_access_valid().

2018-05-31Correct CPACR reset value for v7 coresPeter Maydell1-1/+9
In commit f0aff255700 we made cpacr_write() enforce that some CPACR bits are RAZ/WI and some are RAO/WI for ARMv7 cores. Unfortunately we forgot to also update the register's reset value. The effect was that (a) a guest that read CPACR on reset would not see ones in the RAO bits, and (b) if you did a migration before the guest did a write to the CPACR then the migration would fail because the destination would enforce the RAO bits and then complain that they didn't match the zero value from the source. Implement reset for the CPACR using a custom reset function that just calls cpacr_write(), to avoid having to duplicate the logic for which bits are RAO. This bug would affect migration for TCG CPUs which are ARMv7 with VFP but without one of Neon or VFPv3.
