The emulated mode is associated with a device inheriting from

The Ephemeral one is the simplest way to configure, it lets the device

hw/usb: Add U2F key base class

This patch adds the specification for the U2F key base class.
Used to group the common characteristics, this device class will be
inherited by its two variants, corresponding to the two modes:
passthrough and emulated

This prepares the U2F devices hierarchy which is as follow:
USB device -> u2f-key -> {u2f-passthru, u2f-emulated}.

linux-user: Add support for utimensat_time64() and semtimedop_time64()

This patch introduces functionality for following time64 syscalls:

*utimensat_time64()

    int utimensat(int dirfd, const char *pathname,
                  const struct timespec times[2], int flags);
    -- change file timestamps with nanosecond precision --
    man page: https://man7.org/linux/man-pages/man2/utimensat.2.html

*semtimedop_time64()

    int semtimedop(int semid, struct sembuf *sops, size_t nsops,
                   const struct timespec *timeout);
    -- System V semaphore operations --
    man page: https://www.man7.org/linux/man-pages/man2/semtimedop.2.html

Implementation notes:

   Syscall 'utimensat_time64()' is implemented in similar way as its
   regular variants only difference being that time64 converting function
   is used to convert values of 'struct timespec' between host and target
   ('target_to_host_timespec64()').

   For syscall 'semtimedop_time64()' and additional argument is added
   in function 'do_semtimedop()' through which the aproppriate 'struct timespec'
   converting function is called (false for regular target_to_host_timespec()
   and true for target_to_host_timespec64()). For 'do_ipc()' a
   check was added as that additional argument: 'TARGET_ABI_BITS == 64'.

Unfortunately Docker/Moby does not include unshare in the seccomp.json

virtiofsd: Disable remote posix locks by default

Right now we enable remote posix locks by default. That means when guest
does a posix lock it sends request to server (virtiofsd). But currently
we only support non-blocking posix lock and return -EOPNOTSUPP for
blocking version.

This means that existing applications which are doing blocking posix
locks get -EOPNOTSUPP and fail. To avoid this, people have been
running virtiosd with option "-o no_posix_lock". For new users it
is still a surprise and trial and error takes them to this option.

Given posix lock implementation is not complete in virtiofsd, disable
it by default. This means that posix locks will work with-in applications
in a guest but not across guests. Anyway we don't support sharing
filesystem among different guests yet in virtiofs so this should
not lead to any kind of surprise or regression and will make life
little easier for virtiofs users.

Eduardo Habkost [Fri, 28 Aug 2020 09:02:47 +0000 (10:02 +0100)]
armsse: Define ARMSSEClass correctly

TYPE_ARM_SSE is a TYPE_SYS_BUS_DEVICE subclass, but
ARMSSEClass::parent_class is declared as DeviceClass.

It never caused any problems by pure luck:

We were not setting class_size for TYPE_ARM_SSE, so class_size of
TYPE_SYS_BUS_DEVICE was being used (sizeof(SysBusDeviceClass)).
This made the system allocate enough memory for TYPE_ARM_SSE
devices even though ARMSSEClass was too small for a sysbus
device.

Additionally, the ARMSSEClass::info field ended up at the same
offset as SysBusDeviceClass::explicit_ofw_unit_address.  This
would make sysbus_get_fw_dev_path() crash for the device.
Luckily, sysbus_get_fw_dev_path() never gets called for
TYPE_ARM_SSE devices, because qdev_get_fw_dev_path() is only used
by the boot device code, and TYPE_ARM_SSE devices don't appear at
the fw_boot_order list.
