hw/9pfs: use O_NOFOLLOW for mapped readlink operation
With mapped security models like mapped-xattr and mapped-file, we save the
symlink target as file contents. Now if we ever expose a normal directory
with mapped security model and find real symlinks in export path, never
follow them and return proper error.

rbd: add an asynchronous flush
The existing bdrv_co_flush_to_disk implementation uses rbd_flush(),
which is sychronous and causes the main qemu thread to block until it
is complete. This results in unresponsiveness and extra latency for
the guest.
Fix this by using an asynchronous version of flush. This was added to
librbd with a special #define to indicate its presence, since it will
be backported to stable versions. Thus, there is no need to check the
version of librbd.
Implement this as bdrv_aio_flush, since it matches other aio functions
in the rbd block driver, and leave out bdrv_co_flush_to_disk when the
asynchronous version is available.

Handle CPU interrupts by inline checking of a flag
Fix some of the nasty TCG race conditions and crashes by implementing
cpu_exit() as setting a flag which is checked at the start of each TB.
This avoids crashes if a thread or signal handler calls cpu_exit()
while the execution thread is itself modifying the TB graph (which
may happen in system emulation mode as well as in linux-user mode
with a multithreaded guest binary).
This fixes the crashes seen in LP:668799; however there are another
class of crashes described in LP:1098729 which stem from the fact
that in linux-user with a multithreaded guest all threads will
use and modify the same global TCG date structures (including the
generated code buffer) without any kind of locking. This means that
multithreaded guest binaries are still in the "unsupported"

cpu-exec: wrap tcg_qemu_tb_exec() in a fn to restore the PC
If tcg_qemu_tb_exec() returns a value whose low bits don't indicate a
link to an indexed next TB, this means that the TB execution never
started (eg because the instruction counter hit zero). In this case the
guest PC has to be reset to the address of the start of the TB.
Refactor the cpu-exec code to make all tcg_qemu_tb_exec() calls pass
through a wrapper function which does this restoration if necessary.
Note that the apparent change in cpu_exec_nocache() from calling
cpu_pc_from_tb() with the old TB to calling it with the TB returned by
do_tcg_qemu_tb_exec() is safe, because in the nocache case we can
guarantee that the TB we try to execute is not linked to any others,
so the only possible returned TB is the one we started at. That is,
we should arguably previously have included in cpu_exec_nocache() an
assert(next_tb & ~TB_EXIT_MASK) == tb), since the API requires restore
from next_tb but we were using tb.

DeviceClass::exit still at unparenting time with a realized check.
Make this symmetrical by implementing DeviceClass::unrealize to call it,

chardev: clear O_NONBLOCK on SCM_RIGHTS file descriptors
When we receive a file descriptor over a UNIX domain socket the
O_NONBLOCK flag is preserved. Clear the O_NONBLOCK flag and rely on
QEMU file descriptor users like migration, SPICE, VNC, block layer, and
others to set non-blocking only when necessary.
This change ensures we don't accidentally expose O_NONBLOCK in the QMP

A recent real-world example was when libvirt passed a non-blocking TCP

QEMU produced a corrupted migration stream since its code did not cope
with non-blocking sockets.

socket_connect() sets non-blocking on TCP or UNIX domain sockets if a

There are several code paths in net_init_socket() depending on how the
socket is created: file descriptor passing, UDP multicast, TCP, or UDP.
Some of these support both listen and connect.
Not all code paths set the socket to non-blocking. This patch addresses
the file descriptor passing and UDP cases which were missing
socket_set_nonblock(fd) calls.
I considered moving socket_set_nonblock(fd) to a central location but it
turns out the code paths are different enough to require non-blocking at

qemu-ga: use key-value store to avoid recycling fd handles after restart
Hosts hold on to handles provided by guest-file-open for periods that can
span beyond the life of the qemu-ga process that issued them. Since these
are issued starting from 0 on every restart, we run the risk of issuing
duplicate handles after restarts/reboots.
As a result, users with a stale copy of these handles may end up
reading/writing corrupted data due to their existing handles effectively
being re-assigned to an unexpected file or offset.
We unfortunately do not issue handles as strings, but as integers, so a
solution such as using UUIDs can't be implemented without introducing a
new interface.
As a workaround, we fix this by implementing a persistent key-value store
that will be used to track the value of the last handle that was issued
across restarts/reboots to avoid issuing duplicates.
The store is automatically written to the same directory we currently
set via --statedir to track fsfreeze state, and so should be applicable
for stable releases where this flag is supported.
A follow-up can use this same store for handling fsfreeze state, but
that change is cosmetic and left out for now.

target-ppc: Fix "G2leGP3" PVR
Unlike derived PVR constants mapped to CPU_POWERPC_G2LEgp3, the
"G2leGP3" model definition itself used the CPU_POWERPC_G2LEgp1 PVR.
Fixing this will allow to alias CPU_POWERPC_G2LEgp3-using types to
"G2leGP3".

s390: Fix handling of iscs.
There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.
Unfortunately, we have treated to I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as
- (queued-for-next) kvm made the same mistake, and
- Linux guest kernels don't check the isc value in the I/O interruption
word for subchannel interrupts.
Make sure that we treat the I/O interruption word correctly.

s390: Keep I/O interrupts enabled for all iscs.
do_io_interrupt() would stop scanning further iscs if it found
an I/O interrupt it could inject. This might cause the pending
interrupt indication for I/O interrupts to be reset although there
might be queued I/O interrupts for subsequent iscs.
Fix this by reordering the logic: Inject the I/O interrupt immediately
and continue searching all iscs for queued interrupts.

block-migration: fix pending() and iterate() return values
The return value of .save_live_pending() is the number of bytes
remaining. This is just an estimate because we do not know how many
blocks will be dirtied by the running guest.
Currently our return value for .save_live_pending() is wrong because it
includes dirty blocks but not in-flight bdrv_aio_readv() requests or
unsent blocks. Crucially, it also doesn't include the bulk phase where
the entire device is transferred - therefore we risk completing block
migration before all blocks have been transferred!
The return value of .save_live_iterate() is the number of bytes
transferred this iteration. Currently we return whether there are bytes
remaining, which is incorrect.
Move the bytes remaining calculation into .save_live_pending() and
really return the number of bytes transferred this iteration in
.save_live_iterate().
Also fix the %ld format specifier which was used for a uint64_t
argument. PRIu64 must be use to avoid warnings on 32-bit hosts.

Migration .save_live_iterate() functions return the number of bytes

Make qemu_ftell() public so that block-migration will be able to use it.

does not include buf_size.
