558f5c42ef tests/9pfs: Mark "local" tests as "slow"
The "local" tests can fail on some automated build systems as
reported here:

https://lists.nongnu.org/archive/html/qemu-devel/2020-11/msg05510.html

This will need to be investigated and addressed later. Let's go for a
workaround in the meantime : mark the "local" tests as "slow" so that
they aren't executed with a simple "make check" like in the case above.

c8bf9a9169 qcow2: Fix corruption on write_zeroes with MAY_UNMAP
Commit 205fa50750 ("qcow2: Add subcluster support to zero_in_l2_slice()")
introduced a subtle change to code in zero_in_l2_slice:

It swapped the order of

1. qcow2_cache_entry_mark_dirty(s->l2_table_cache, l2_slice);
2. set_l2_entry(s, l2_slice, l2_index + i, QCOW_OFLAG_ZERO);
3. qcow2_free_any_clusters(bs, old_offset, 1, QCOW2_DISCARD_REQUEST);

To

1. qcow2_cache_entry_mark_dirty(s->l2_table_cache, l2_slice);
2. qcow2_free_any_clusters(bs, old_offset, 1, QCOW2_DISCARD_REQUEST);
3. set_l2_entry(s, l2_slice, l2_index + i, QCOW_OFLAG_ZERO);

It seems harmless, however the call to qcow2_free_any_clusters can
trigger a cache flush which can mark the L2 table as clean, and
assuming that this was the last write to it, a stale version of it
will remain on the disk.

Now we have a valid L2 entry pointing to a freed cluster. Oops.

d2abc563e4 net: purge queued rx packets on queue deletion
https://bugzilla.redhat.com/show_bug.cgi?id=1829272
When deleting queue pair, purge pending RX packets if any.
Example of problematic flow:
1. Bring up q35 VM with tap (vhost off) and virtio-net or e1000e
2. Run ping flood to the VM NIC ( 1 ms interval)
3. Hot unplug the NIC device (device_del)
   During unplug process one or more packets come, the NIC
   can't receive, tap disables read_poll
4. Hot plug the device (device_add) with the same netdev
The tap stays with read_poll disabled and does not receive
any packets anymore (tap_send never triggered)

ad6f932fe8 net: do not exit on "netdev_add help" monitor command
"netdev_add help" is causing QEMU to exit because the code that
invokes show_netdevs is shared between CLI and HMP processing.
Move the check to the callers so that exit(0) remains only
in the CLI flow.

"netdev_add help" is not fixed by this patch; that is left for
later work.

c2cb511634 hw/net/e1000e: advance desc_offset in case of null descriptor
While receiving packets via e1000e_write_packet_to_guest() routine,
'desc_offset' is advanced only when RX descriptor is processed. And
RX descriptor is not processed if it has NULL buffer address.
This may lead to an infinite loop condition. Increament 'desc_offset'
to process next descriptor in the ring to avoid infinite loop.

cf254988a5 vfio: Make migration support experimental
Support for migration of vfio devices is still in flux.  Developers
are attempting to add support for new devices and new architectures,
but none are yet readily available for validation.  We have concerns
whether we're transferring device resources at the right point in the
migration, whether we're guaranteeing that updates during pre-copy are
migrated, and whether we can provide bit-stream compatibility should
any of this change.  Even the question of whether devices should
participate in dirty page tracking during pre-copy seems contentious.
In short, migration support has not had enough soak time and it feels
premature to mark it as supported.

Create an experimental option such that we can continue to develop.

[Retaining previous acks/reviews for a previously identical code
 change with different specifics in the commit log.]

c5d7cfdaac docs/system/virtio-pmem.rst: Fix minor style issues
The virtio-pmem documentation has some minor style issues we hadn't
noticed since we weren't rendering it in our docs:

 * Sphinx doesn't complain about overlong title-underlining the
   way it complains about too-short underlining, but it looks odd;
   make the underlines of section headers the right length

 * Indent of paragraphs makes them render as blockquotes;
   remove the indent so they just render as normal text

 * Leading 'o' isn't rst markup, so it just renders as a literal
   "o"; reformat as a subsection heading instead

 * "QEMU" in the document title and section headings are a bit
   odd and unnecessary since this is the QEMU manual; delete
   or rephrase them

 * There's no need to specify what QEMU version the device first
   appeared in.

acebed948c linux-user/arm: Deliver SIGTRAP for UDF patterns used as breakpoints
The Linux kernel doesn't use the official bkpt insn for breakpoints;
instead it uses three instructions in the guaranteed-to-UNDEF space,
and generates SIGTRAP for these rather than the SIGILL that most
UNDEF insns generate:

https://elixir.bootlin.com/linux/v5.9.8/source/arch/arm/kernel/ptrace.c#L197

Make QEMU treat these insns specially too.  The main benefit of this
is that if you're running a debugger on a guest program that runs
into a GCC __builtin_trap() or LLVM "trap because execution should
never reach here" then you'll get the expected signal rather than a
SIGILL.

6951595183 target/arm: Make SYS_HEAPINFO work with RAM that doesn't start at 0
The semihosting SYS_HEAPINFO call is supposed to return an array
of four guest addresses:
 * base of heap memory
 * limit of heap memory
 * base of stack memory
 * limit of stack memory

Some semihosting programs (including those compiled to use the
'newlib' embedded C library) use this call to work out where they
should initialize themselves to.

QEMU's implementation when in system emulation mode is very
simplistic: we say that the heap starts halfway into RAM and
continues to the end of RAM, and the stack starts at the top of RAM
and works down to the bottom.  Unfortunately the code assumes that
the base address of RAM is at address 0, so on boards like 'virt'
where this is not true the addresses returned will all be wrong and
the guest application will usually crash.

Conveniently since all Arm boards call arm_load_kernel() we have the
base address of the main RAM block in the arm_boot_info struct which
is accessible via the CPU object.  Use this to return sensible values
from SYS_HEAPINFO.

Since commit aa35ec2213 ("hw/arm/raspi: Use more specific

Note, rather than the raspi3b, the raspi3ap introduced in
commit 5be94252d3 ("hw/arm/raspi: Add the Raspberry Pi 3
model A+") is a closer match to what QEMU models, but only
provides 512 MB of RAM.

As more Raspberry Pi 2/3 models are emulated, in order
to avoid confusion, deprecate the raspi2/raspi3 machine
aliases.

ac74e282d4 gitlab: move remaining x86 check-tcg targets to gitlab
The GCC check-tcg (user) test in particular was very prone to timing
out on Travis. We only actually need to move the some-softmmu builds
across as we already have coverage for linux-user.

As --enable-debug-tcg does increase the run time somewhat as more
debug is put in let's restrict that to just the plugins build. It's
unlikely that a plugins enabled build is going to hide a sanity
failure in core TCG code so let the plugin builds do the heavy lifting
on checking TCG sanity so the non-plugin builds can run swiftly.

Now the only remaining check-tcg builds on Travis are for the various
non-x86 arches.

8c175c63ee tests: add prefixes to the bare mkdtemp calls
The first step to debug a thing is to know what created the thing in
the first place. Add some prefixes so random tmpdir's have something
grep in the code.

3d6519968b pc-bios: s390x: Clear out leftover S390EP string
A Linux binary will have the string "S390EP" at address 0x10008,
which is important in getting the guest up off the ground. In the
case of a reboot (specifically chreipl going to a new device),
we should defer to the PSW at address zero for the new config,
which will re-write "S390EP" from the new image.

Let's clear it out at this point so that a reipl to, say, a DASD
passthrough device drives the IPL path from scratch without disrupting
disrupting the order of operations for other boots.

Rather than hardcoding the address of this magic (again), let's
define it somewhere so that the two users are visibly related.
