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.

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.

* 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.

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

4 years agoconsole: fix cell overflow
Gerd Hoffmann [Mon, 1 Jul 2019 07:53:01 +0000 (09:53 +0200)]
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.

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.

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

the absence of the code in this patch, as they use alternative code
paths for handling floating point exceptions (see, for example,
invocations of update_fcr31()) - they rely on softfloat library for
keeping track on exceptions that needs to be raised. However, there
are few MIPS FP instructions (an example is CTC1) that use function
do_raise_exception() directly, and they need the case that is added
in this patch to propagate the FPE exception as designed.

The code is based on kernel's function force_fcr31_sig() in

linux-user: Introduce TARGET_HAVE_ARCH_STRUCT_FLOCK

Bring target_flock definitions to be more in sync with the way
flock is defined in kernel.

Basically, the rules from the kernel are:

1. Majority of architectures have a common flock definition.

2. Architectures with 32-bit MIPS ABIs have a sligtly different
flock definition; those architectures are the only arcitectures
that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor
constant is used in the common header as a flag for including or
not including common flock definition.

3. Sparc architectures also have a sligtly different flock
definition, but the difference is only the padding at the end of
the structure. The presence of that padding is determined by
preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD.

QEMU linux-user already implements rules 1. and 3. in a very
similar way as they are implemented in kernel. However, rule 2.
is implemented in a dissimilar way (for example, the constant
TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings
QEMU implementation much closer to the kernel implementation.
TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to
mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined
anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64
in kernel as well.

4 years agolinux-user: Add support for translation of statx() syscall
Aleksandar Rikalo [Fri, 28 Jun 2019 10:43:34 +0000 (12:43 +0200)]
linux-user: Add support for translation of statx() syscall

Implement support for translation of system call statx().

The implementation is based on "best effort" approach: if host
is capable of executing statx(), host statx() is used. If not,
the implementation includes invoking a more mature system call
fstatat() on the host side to achieve as close as possible
functionality.

Support for statx() in kernel and glibc was, however, introduced
at different points of time (the difference is more than a year):

  - kernel: Linux 4.11 (30 April 2017)
  - glibc: glibc 2.28 (1 Aug 2018)

In this patch, the availability of statx() support is established
via __NR_statx (if it is defined, statx() is considered available).
This coincedes with statx() introduction in kernel.

However, the structure statx definition may not be available in
any header for hosts with glibc older than 2.28 (and it is, by
design, to be defined in one of glibc headers), even though the
full statx() functionality may be supported in kernel. Hence, a
structure "target_statx" is defined in this patch, to remove that
dependency on glibc headers, and to use statx() functionality as
soon as the host kernel is capable of supporting it. Such statx
structure definition is used for both target and host structures
statx (of course, this doesn't mean the endian arrangement is
the same on target and host - the endian conversion is done in
all necessary cases).
