Gerd Hoffmann 7f71d5051e tests/vm: run test builds on snapshot
The build script doesn't shutdown the guest VMs properly,
which results in filesystem corruption and guest boot
failures sooner or later.

Use the --snapshot to run builds on a snapshot,
That way killing the VM doesn't corrupt the base image.

Gerd Hoffmann b08ba163aa tests/vm: send proxy environment variables over ssh
Packages are fetched via proxy that way, if configured on the host.
That might be required to pass firewalls, and it allows to route
package downloads through a caching proxy server.

Needs AcceptEnv setup in sshd_config on the guest side to work.

Cleber Rosa 95c44c250d tests/vm: add source repos on ubuntu.i386
Possibly because of different behavior on the newly update
cloud-image, trying to run 'apt-get build-dep' results in:

   E: You must put some 'source' URIs in your sources.list

This enables all source repos (even though some are not
needed) for simplicity sake.

It's a good practice to always have the same components used in tests.
According to:

New images are released from time to time, and the "release/"
directory points to the latest release.  Let's pin to the latest
available version, and while at it, set a hash for verification.

Coverity points out (CID 1402195) that the loop in trans_VMOV_imm_dp()
that iterates over the destination registers in a short-vector VMOV
accidentally throws away the returned updated register number
from vfp_advance_dreg(). Add the missing assignment. (We got this
correct in trans_VMOV_imm_sp().)

Peter Maydell 5529de1e55 target/arm: Execute Thumb instructions when their condbits are 0xf
Thumb instructions in an IT block are set up to be conditionally
executed depending on a set of condition bits encoded into the IT
bits of the CPSR/XPSR.  The architecture specifies that if the
condition bits are 0b1111 this means "always execute" (like 0b1110),
not "never execute"; we were treating it as "never execute".  (See
the ConditionHolds() pseudocode in both the A-profile and M-profile
Arm ARM.)

This is a bit of an obscure corner case, because the only legal
way to get to an 0b1111 set of condbits is to do an exception
return which sets the XPSR/CPSR up that way. An IT instruction
which encodes a condition sequence that would include an 0b1111 is
UNPREDICTABLE, and for v8A the CONSTRAINED UNPREDICTABLE choices
for such an IT insn are to NOP, UNDEF, or treat 0b1111 like 0b1110.
Add a comment noting that we take the latter option.

Like most of the v7M memory mapped system registers, the systick

Peter Maydell be32116e32 target/arm: v8M: Check state of exception being returned from
In v8M, an attempt to return from an exception which is not
active is an illegal exception return. For this purpose,
exceptions which can configurably target either Secure or
NonSecure are not considered to be active if they are
configured for the opposite security state for the one
we're trying to return from (eg attempt to return from
an NS NMI but NMI targets Secure). In the pseudocode this
is handled by IsActiveForState().

Detect this case rather than counting an active exception
possibly of the wrong security state as being sufficient.

Peter Maydell 077d744910 arm v8M: Forcibly clear negative-priority exceptions on deactivate
To prevent execution priority remaining negative if the guest
returns from an NMI or HardFault with a corrupted IPSR, the
v8M interrupt deactivation process forces the HardFault and NMI
to inactive based on the current raw execution priority,
even if the interrupt the guest is trying to deactivate
is something else. In the pseudocode this is done in the
Deactivate() function.

RISC-V Patches for the 4.1 Soft Freeze, Part 2 v3

This pull request contains a handful of patches that I'd like to target
for the 4.1 soft freeze.  There are a handful of new features:

* Support for the 1.11.0, the latest privileged specification.
* Support for reading and writing the PRCI registers.
* Better control over the ISA of the target machine.
* Support for the cpu-topology device tree node.

Additionally, there are a handful of bug fixes including:

* Load reservations are now broken by both store conditional and by
  scheduling, which fixes issues with parallel applications.
* Various fixes to the PMP implementation.
* Fixes to the 32-bit linux-user syscall ABI.
* Various fixes for instruction decodeing.
* A fix to the PCI device tree "bus-range" property.

This boots 32-bit and 64-bit OpenEmbedded.

Changes since v2 [riscv-for-master-4.1-sf1-v2]:

* Dropped OpenSBI.

Changes since v1 [riscv-for-master-4.1-sf1]:

* Contains a fix to the sifive_u OpenSBI integration.

Kashyap Chamarthy a2230bd778 VirtIO-RNG: Update default entropy source to /dev/urandom
When QEMU exposes a VirtIO-RNG device to the guest, that device needs a
source of entropy, and that source needs to be "non-blocking", like
`/dev/urandom`.  However, currently QEMU defaults to the problematic
`/dev/random`, which on Linux is "blocking" (as in, it waits until
sufficient entropy is available).

Why prefer `/dev/urandom` over `/dev/random`?
---------------------------------------------

The man pages of urandom(4) and random(4) state:

    "The /dev/random device is a legacy interface which dates back to a
    time where the cryptographic primitives used in the implementation
    of /dev/urandom were not widely trusted.  It will return random
    bytes only within the estimated number of bits of fresh noise in the
    entropy pool, blocking if necessary.  /dev/random is suitable for
    applications that need high quality randomness, and can afford
    indeterminate delays."

Further, the "Usage" section of the said man pages state:

    "The /dev/random interface is considered a legacy interface, and
    /dev/urandom is preferred and sufficient in all use cases, with the
    exception of applications which require randomness during early boot
    time; for these applications, getrandom(2) must be used instead,
    because it will block until the entropy pool is initialized.

    "If a seed file is saved across reboots as recommended below (all
    major Linux distributions have done this since 2000 at least), the
    output is cryptographically secure against attackers without local
    root access as soon as it is reloaded in the boot sequence, and
    perfectly adequate for network encryption session keys.  Since reads
    from /dev/random may block, users will usually want to open it in
    nonblocking mode (or perform a read with timeout), and provide some
    sort of user notification if the desired entropy is not immediately
    available."

And refer to random(7) for a comparison of `/dev/random` and
`/dev/urandom`.

What about other OSes?
----------------------

`/dev/urandom` exists and works on OS-X, FreeBSD, DragonFlyBSD, NetBSD
and OpenBSD, which cover all the non-Linux platforms we explicitly
support, aside from Windows.

On Windows `/dev/random` doesn't work either so we don't regress.
This is actually another argument in favour of using the newly
proposed 'rng-builtin' backend by default, as that will work on
Windows.

    - - -

Given the above, change the entropy source for VirtIO-RNG device to
`/dev/urandom`.

Markus Armbruster 1338a4b726 Makefile: Reuse all's recursion machinery for clean and install
Targets "clean" and "install" run make recursively in a for loop.
This ignores -j and -k.  Target "all" depends on SUBDIR/all to recurse
into each SUBDIR.  Behaves nicely with -j and -k.  Put that to use for
"clean" and "install": depend on SUBDIR/clean or SUBDIR/install,
respectively, and delete the loop.

Markus Armbruster 3b8593eeaa Makefile: Rename targets for make recursion
We make a few sub-directories recursively, in particular
$(TARGET_DIRS).

For goal "all", we do it the nice way: "all" has a prerequisite
subdir-T for each T in $(TARGET_DIRS), and T's recipe runs make
recursively.  Behaves nicely with -j and -k.

For other goals such as "clean" and "install", the recipe runs make
recursively in a for loop.  Ignores -j and -k.

The next commit will fix that for "clean" and "install".  This commit
prepares the ground by renaming the targets we use for "all" to
include the goal for the sub-make.  This will permit reusing them for
goals other than "all".

Targets subdir-T for T in $(TARGET_DIRS) run "make all" in T.  Rename
to T/all, and declare phony.

Targets romsubdir-R for R in $(ROMS) run "make" in pc-bios/R.  Default
goal is "all" for all R.  Rename to pc-bios/R/all, and declare phony.

The remainder are renamed just for consistency.

Target subdir-dtc runs "make libbft/libfdt.a" in dtc.  Rename to
dtc/all, and declare phony.

Target subdir-capstone runs make $(BUILD_DIR)/capstone/$(LIBCAPSTONE)
in $(SRC_PATH)/capstone.  Rename to capstone/all, and declare phony.

Target subdir-slirp runs "make" in $(SRC_PATH)/slirp.  Default goal is
all, which builds $(BUILD_DIR)/libslirp.a.  Rename to slirp/all, and
declare phony.

Gerd Hoffmann 5b8541c6c7 console: fix cell overflow
Linux terminal behavior (coming from vt100 I think) is somewhat strange
when it comes to line wraps:  When a character is printed to the last
char cell of a line the cursor does NOT jump to the next line but stays
where it is.  The line feed happens when the next character is printed.

So the valid range for the cursor position is not 0 .. width-1 but
0 .. width, where x == width represents the state where the line is
full but the cursor didn't jump to the next line yet.

The code for the 'clear from start of line' control sequence (ESC[1K)
fails to handle this corner case correctly and may call
console_clear_xy() with x == width.  That will incorrectly clear the
first char cell of the next line, or in case the cursor happens to be on
the last line overflow the cell buffer by one character (three bytes).

Add a check to the loop to fix that.

Didn't spot any other places with the same problem.  But it's easy to
miss that corner case, so also allocate one extra cell as precaution, so
in case we have simliar issues lurking elsewhere it at least wouldn't be
a buffer overflow.

v2: squashed in additional checks suggested by Christophe de Dinechin.

Peter Maydell 41742927ee hw/i2c/bitbang_i2c: Use in-place rather than malloc'd bitbang_i2c_interface struct
Currently the bitbang_i2c_init() function allocates a
bitbang_i2c_interface struct which it returns.  This is unfortunate
because it means that if the function is used from a DeviceState
init method then the memory will be leaked by an "init then delete"
cycle, as used by the qmp/hmp commands that list device properties.

Since three out of four of the uses of this function are in
device init methods, switch the function to do an in-place
initialization of a struct that can be embedded in the
device state struct of the caller.

This fixes LeakSanitizer leak warnings that have appeared in the
patchew configuration (which only tries to run the sanitizers
for the x86_64-softmmu target) now that we use the bitbang-i2c
code in an x86-64 config.

On very busy networks connected via a tap interface, it is possible to overflow
the RX descriptor ring in the time between the client driver enabling the RX
MAC and finishing writing the final configuration to the NIC registers.

Ensure that we detect this condition and update the status register accordingly
to indicate an overflow has occurred (and the incoming packet dropped) in order

ppc patch queue 2019-07-2

Here's my next pull request for qemu-4.1.  I'm not sure if this will
squeak in just before the soft freeze, or just after.  I don't think
it really matters - most of this is bugfixes anyway.  There's some
cleanups which aren't stictly bugfixes, but which I think are safe
enough improvements to go in the soft freeze.  There's no true feature
work.

Unfortunately, I wasn't able to complete a few of my standard battery
of pre-pull tests, due to some failures that appear to also be in
master.  I'm hoping that hasn't missed anything important in here.

Highlights are:
  * A number of fixe and cleanups for the XIVE implementation
  * Cleanups to the XICS interrupt controller to fit better with the new
    XIVE code
  * Numerous fixes and improvements to TCG handling of ppc vector
    instructions
  * Remove a number of unnnecessary #ifdef CONFIG_KVM guards
  * Fix some errors in the PCI hotplug paths
  * Assorted other fixes

David Hildenbrand 1e33b513f2 virtio-pci: Allow to specify additional interfaces for the base type
Let's allow to specify additional interfaces for the base type (e.g.
later TYPE_MEMORY_DEVICE), something that was possible before the
rework of virtio PCI device instantiation.

Pankaj Gupta 5f503cd9f3 virtio-pmem: add virtio device
This is the implementation of virtio-pmem device. Support will require
machine changes for the architectures that will support it, so it will
not yet be compiled. It can be unlocked with VIRTIO_PMEM_SUPPORTED per
machine and disabled globally via VIRTIO_PMEM.

We cannot use the "addr" property as that is already used e.g. for
virtio-pci/pci devices. And we will have e.g. virtio-pmem-pci as a proxy.
So we have to choose a different one (unfortunately). "memaddr" it is.
That name should ideally be used by all other virtio-* based memory
devices in the future.
    -device virtio-pmem-pci,id=p0,bus=bux0,addr=0x01,memaddr=0x1000000...
