virtio_balloon: prevent uninitialized variable use
virtio-balloon: use actual number of stats for stats queue buffers
virtio_balloon: init 1st buffer in stats vq
virtio_pci: fix out of bound access for msix_names
The latest gcc-7.0.1 snapshot reports a new warning:
virtio/virtio_balloon.c: In function 'update_balloon_stats':
virtio/virtio_balloon.c:258:26: error: 'events[2]' is used uninitialized in this function [-Werror=uninitialized]

virtio/virtio_balloon.c:262:56: error: 'events[17]' is used uninitialized in this function [-Werror=uninitialized]
This seems absolutely right, so we should add an extra check to
prevent copying uninitialized stack data into the statistics.
>From all I can tell, this has been broken since the statistics code
was originally added in 2.6.34.

The virtio balloon driver contained a not-so-obvious invariant that
update_balloon_stats has to update exactly VIRTIO_BALLOON_S_NR counters
in order to send valid stats to the host. This commit fixes it by having
update_balloon_stats return the actual number of counters, and its
callers use it when pushing buffers to the stats virtqueue.
Note that it is still out of spec to change the number of counters
at run-time. "Driver MUST supply the same subset of statistics in all
buffers submitted to the statsq."

When init_vqs runs, virtio_balloon.stats is either uninitialized or
contains stale values. The host updates its state with garbage data
because it has no way of knowing that this is just a marker buffer
used for signaling.
This patch updates the stats before pushing the initial buffer.
Alternative fixes:
* Push an empty buffer in init_vqs. Not easily done with the current
virtio implementation and violates the spec "Driver MUST supply the
same subset of statistics in all buffers submitted to the statsq".
* Push a buffer with invalid tags in init_vqs. Violates the same
spec clause, plus "invalid tag" is not really defined.
Note: the spec says:
When using the legacy interface, the device SHOULD ignore all values in
the first buffer in the statsq supplied by the driver after device
initialization. Note: Historically, drivers supplied an uninitialized
buffer in the first buffer.
Unfortunately QEMU does not seem to implement the recommendation
even for the legacy interface.

The crashes are not always consistent but they are generally
some flavor of oops or GPF in virtio related code. Multiple people

The nested_ept_enabled flag introduced in commit 7ca29de213 was not
computed correctly. We are interested only in L1's EPT state, not the
the combined L0+L1 value.
In particular, if L0 uses EPT but L1 does not, nested_ept_enabled must
be false to make sure that PDPSTRs are loaded based on CR3 as usual,
because the special case described in 26.3.2.4 Loading Page-Directory-
Pointer-Table Entries does not apply.

It is a driver for new hardware which people don't have yet so it

It is wrong way to read link name from a build-id file. Because a
build-id file is not anymore a symbolic link but build-id directory of
it is symbolic link, so fix it.
For example, if build-id file name gotten from
dso__build_id_filename() is as below,
/root/.debug/.build-id/4f/75c7d197c951659d1c1b8b5fd49bcdf8f3f8b1/elf
To correctly read link name of build-id, use the build-id dir path that
is a symbolic link, instead of the above build-id file name like below.
/root/.debug/.build-id/4f/75c7d197c951659d1c1b8b5fd49bcdf8f3f8b1

Often it is interesting to know how costly a given source line is in
total. Previously, one had to build these sums manually based on all
addresses that pointed to the same source line. This patch introduces
srcline as a sort key, which will do the aggregation for us.
Paired with the recent addition of showing inline frames, this makes
perf report much more useful for many C++ work loads.
The following shows the new feature in action. First, let's show the
status quo output when we sort by address. The result contains many hist
entries that generate the same output:

It would be useful for perf to support a mode to query the inline stack
for a given callgraph address. This would simplify finding the right
code in code that does a lot of inlining.
The srcline.c has contained the code which supports to translate the
address to filename:line_nr. This patch just extends the function to let
it support getting the inline stacks.
It introduces the inline_list which will store the inline function
result (filename:line_nr and funcname).
If BFD lib is not supported, the result is only filename:line_nr.

Introduce dso__name() and filename_split() out of existing code because
these codes will be used in several places in next patch.
For filename_split(), it may also solve a potential memory leak in
existing code. In existing addr2line(),
sep = strchr(filename, ':');
if (sep) {
*sep++ = '\0';
*file = filename;
*line_nr = strtoul(sep, NULL, 0);
ret = 1;
}
out:
pclose(fp);
return ret;
If sep is NULL, filename is not freed or returned via file.

"This has been a slow -rc cycle for the RDMA subsystem. We really
haven't had a lot of rc fixes come in. This pull request is the first
of this entire rc cycle and it has all of the suitable fixes so far
and it's still only about 20 patches. The fix for the minor breakage
cause by the dma mapping patchset is in here, as well as a couple
other potential oops fixes, but the rest is more minor.
Summary:

and IOMMU operation
- a few other oops fixes

"We've got an audit fix, and unfortunately it is big.
While I'm not excited that we need to be sending you something this
large during the -rcX phase, it does fix some very real, and very
tangled, problems relating to locking, backlog queues, and the audit
daemon connection.
This code has passed our testsuite without problem and it has held up
to my ad-hoc stress tests (arguably better than the existing code),
please consider pulling this as fix for the next v4.11-rcX tag"

When the rdma device is removed, we must cleanup all
the rdma resources within the DEVICE_REMOVAL event
handler to let the device teardown gracefully. When
this happens with live I/O, some memory regions are
occupied. Thus, track them too and dereg all the mr's.
We are safe with mr access by iscsi_iser_cleanup_task.
