help: Provide help for egl-headless
EGL headless has been missing from QEMU's help or man page, we should
mention that such a thing exists, especially since projects like libvirt
might rely on that. This patch also adds the newly introduced option for

Coverity complains (CID
1390847) about some dead code in
do_sigreturn(). This is an if (err) clause that can never be
true, copied from the kernel (where __get_user returns an error).
The one code path that could report an error is in the
currently commented-out pseudocode for handling FPU register
restoring, so move the if into that comment (and fix the
broken indent in the comment in the process).
(The new position for the error check is also the semantically

the signal frame if we get an error here, so the check must
be done before set_sigmask(), not after.)

target/arm: Hyp mode R14 is shared with User and System
Hyp mode is an exception to the general rule that each AArch32
mode has its own r13, r14 and SPSR -- it has a banked r13 and
SPSR but shares its r14 with User and System mode. We were
incorrectly implementing it as banked, which meant that on
entry to Hyp mode r14 was 0 rather than the USR/SYS r14.
We provide a new function r14_bank_number() which is like
the existing bank_number() but provides the index into
env->banked_r14[]; bank_number() provides the index to use
for env->banked_r13[] and env->banked_cpsr[].
All the points in the code that were using bank_number()
to index into env->banked_r14[] are updated for consintency:
* switch_mode() -- this is the only place where we fix
an actual bug
* aarch64_sync_32_to_64() and aarch64_sync_64_to_32():
no behavioural change as we already special-cased Hyp R14
* kvm32.c: no behavioural change since the guest can't ever
be in Hyp mode, but conceptually the right thing to do
* msr_banked()/mrs_banked(): we can never get to the case
that accesses banked_r14[] with tgtmode == ARM_CPU_MODE_HYP,

target/arm: Correctly implement handling of HCR_EL2.{VI, VF}
In commit
8a0fc3a29fc2315325400 we tried to implement HCR_EL2.{VI,VF},
but we got it wrong and had to revert it.
In that commit we implemented them as simply tracking whether there
is a pending virtual IRQ or virtual FIQ. This is not correct -- these
bits cause a software-generated VIRQ/VFIQ, which is distinct from
whether there is a hardware-generated VIRQ/VFIQ caused by the
external interrupt controller. So we need to track separately
the HCR_EL2 bit state and the external virq/vfiq line state, and
OR the two together to get the actual pending VIRQ/VFIQ state.

target/arm: Track the state of our irq lines from the GIC explicitly
Currently we track the state of the four irq lines from the GIC
only via the cs->interrupt_request or KVM irq state. That means
that we assume that an interrupt is asserted if and only if the
external line is set. This assumption is incorrect for VIRQ
and VFIQ, because the HCR_EL2.{VI,VF} bits allow assertion
of VIRQ and VFIQ separately from the state of the external line.
To handle this, start tracking the state of the external lines
explicitly in a CPU state struct field, as is common practice
for devices.
The complicated part of this is dealing with inbound migration
from an older QEMU which didn't have this state. We assume in
that case that the older QEMU did not implement the HCR_EL2.{VI,VF}
bits as generating interrupts, and so the line state matches
the current state in cs->interrupt_request. (This is not quite
true between commit
8a0fc3a29fc2315325400c7 and its revert, but
that commit is broken and never made it into any released QEMU
version.)

This reverts commit
8a0fc3a29fc2315325400c738f807d0d4ae0ab7f.
The implementation of HCR.VI and VF in that commit is not
correct -- they do not track the overall "is there a pending
VIRQ or VFIQ" status, but whether there is a pending interrupt
due to "this mechanism", ie the hypervisor having set the VI/VF
bits. The overall pending state for VIRQ and VFIQ is effectively
the logical OR of the inbound lines from the GIC with the
VI and VF bits. Commit
8a0fc3a29fc231 would result in pending
VIRQ/VFIQ possibly being lost when the hypervisor wrote to HCR.
As a preliminary to implementing the HCR.VI/VF feature properly,
revert the broken one entirely.

infrastructure to inject the exception into the guest. However, we are
missing a full setup of the exception structure, causing an assert
later down the line.

hw/arm/sysbus-fdt: Only call match_fn callback if the type matches
Commit
af7d64ede0b9 (hw/arm/sysbus-fdt: Allow device matching with DT
compatible value) introduced a match_fn callback which gets called
for each registered combo to check whether a sysbus device can be
dynamically instantiated. However the callback gets called even if
the device type does not match the binding combo typename field.
This causes an assert when passing "-device ramfb" to the qemu
command line as vfio_platform_match() gets called on a non
vfio-platform device.
To fix this regression, let's change the add_fdt_node() logic so
that we first check the type and if the match_fn callback is defined,
then we also call it.
Binding combos only requesting a type check do not define the
match_fn callback.

If we know we've already locked the bytes, don't do it again; similarly
don't unlock a byte if we haven't locked it. This doesn't change the
behavior, but fixes a corner case explained below.
Libvirt had an error handling bug that an image can get its (ownership,
file mode, SELinux) permissions changed (RHBZ
1584982) by mistake behind
QEMU. Specifically, an image in use by Libvirt VM has:
$ ls -lhZ b.img
-rw-r--r--. qemu qemu system_u:object_r:svirt_image_t:s0:c600,c690 b.img
Trying to attach it a second time won't work because of image locking.
And after the error, it becomes:
$ ls -lhZ b.img
-rw-r--r--. root root system_u:object_r:virt_image_t:s0 b.img
Then, we won't be able to do OFD lock operations with the existing fd.
In other words, the code such as in blk_detach_dev:
blk_set_perm(blk, 0, BLK_PERM_ALL, &error_abort);
can abort() QEMU, out of environmental changes.
This patch is an easy fix to this and the change is regardlessly
reasonable, so do it.

linux-user: Don't call gdb_handlesig() before queue_signal()
The CPU main-loop routines for linux-user generally
call gdb_handlesig() when they're about to queue a
SIGTRAP signal. This is wrong, because queue_signal()
will cause us to pend a signal, and process_pending_signals()
will then call gdb_handlesig() itself. So the effect is that
we notify gdb of the SIGTRAP, and then if gdb says "OK,
continue with signal X" we will incorrectly notify
gdb of the signal X as well. We don't do this double-notify
for anything else, only SIGTRAP.
Remove this unnecessary and incorrect code from all
the targets except for nios2 (whose main loop is
doing something different and broken, and will be handled
in a separate patch).
This bug only manifests if the user responds to the reported
SIGTRAP using "signal SIGFOO" rather than "continue"; since
the latter is the overwhelmingly common thing to do after a
breakpoint most people won't have hit this.

linux-user: Remove dead error-checking code
Remove some dead code spotted by Coverity (CID
1009855,
1390854,
1390847). The underlying cause in all these cases
is the same: QEMU's put_user operations can't result in
errors, but the kernel's equivalent does. So when code
was copied from the kernel signal-frame-setup/teardown
code, checks on error flags that were needed in the kernel
became dead code for us.

slirp: fork_exec(): create and connect child socket before fork()
Currently fork_exec() fork()s, and then creates and connects the
child socket which it uses for communication with the parent in
the child process. This is awkward because the child has no
mechanism to report failure back to the parent, which might end
up blocked forever in accept(). The child code also has an issue
pointed out by Coverity (CID

call fails it will pass -1 as a file descriptor to connect().
Fix these issues by moving the creation of the child's end of
the socket to before the fork(), where we are in a position to
handle a possible failure.

because various places in the code do so->s = qemu_socket(...) and so
will end up with so->s == -1 on failure, and not all the paths which

9p: write lock path in v9fs_co_open2()
The assumption that the fid cannot be used by any other operation is
wrong. At least, nothing prevents a misbehaving client to create a
file with a given fid, and to pass this fid to some other operation
at the same time (ie, without waiting for the response to the creation
request). The call to v9fs_path_copy() performed by the worker thread
after the file was created can race with any access to the fid path
performed by some other thread. This causes use-after-free issues that
can be detected by ASAN with a custom 9p client.
Unlike other operations that only read the fid path, v9fs_co_open2()
does modify it. It should hence take the write lock.

There are still three patch sets that I'd like to try to get up for 3.1:

issues he found when converting our port to decodetree.
* An as-of-yet-unwritten fix to the third issue that Basian pointed out.
* A fix to our fflags bug, which is currently coupled to some CSR
refactoring that I don't think is OK for 3.1.

replay: Exit on errors reading from replay log
Currently replay_get_byte() does not check for an error
from getc(). Coverity points out (CID
1390622) that this
could result in unexpected behaviour (such as looping
forever, if we use the replay_get_dword() return value
for a loop count). We don't expect reads from the replay
log to fail, and if they do there is no way we can
continue. So make them fatal errors.

Add the spapr cap SPAPR_CAP_NESTED_KVM_HV to be used to control the
availability of nested kvm-hv to the level 1 (L1) guest.
Assuming a hypervisor with support enabled an L1 guest can be allowed to
use the kvm-hv module (and thus run it's own kvm-hv guests) by setting:
-machine pseries,cap-nested-hv=true
or disabled with:
-machine pseries,cap-nested-hv=false

target/ppc: Add one reg id for ptcr
The ptcr (partition table control register) is used to store the address

guest register the location of it's partition table with the hypervisor.
Thus to support migration we need to be able to read this out of kvm

hw/ppc/ppc440_uc: Remove dead code in sdram_size()
Coverity points out in CID
1390588 that the test for sh == 0
in sdram_size() can never fire, because we calculate sh with
sh = 1024 - ((bcr >> 6) & 0x3ff);
which must result in a value between 1 and 1024 inclusive.
Without the relevant manual for the SoC, we're not completely
sure of the correct behaviour here, but we can remove the
dead code without changing how QEMU currently behaves.

In ppc_core99_init(), we allocate an openpic_irqs array, which
we then use to collect up the various qemu_irqs which we're
going to connect to the interrupt controller. Once we've
called sysbus_connect_irq() to connect them all up, the
array is no longer required, but we forgot to free it.
Since board init is only run once at startup, the memory
leak is not a significant one.

When allocating an array, it is a recommended coding practice to call

it takes care to avoid overflow when calculating the size of the
