[ Upstream commit 35a089b5d7 ]
Checking the bearer min mtu with tipc_udp_mtu_bad() only works for
IPv4 UDP bearer, and IPv6 UDP bearer has a different value for the
min mtu. This patch checks with encap_hlen + TIPC_MIN_BEARER_MTU
for min mtu, which works for both IPv4 and IPv6 UDP bearer.
Note that tipc_udp_mtu_bad() is still used to check media min mtu
in __tipc_nl_media_set(), as m->mtu currently is only used by the
IPv4 UDP bearer as its default mtu value.

[ Upstream commit 56077b56cd ]
When doing link mtu negotiation, a malicious peer may send Activate msg
with a very small mtu, e.g. 4 in Shuang's testing, without checking for
the minimum mtu, l->mtu will be set to 4 in tipc_link_proto_rcv(), then
n->links[bearer_id].mtu is set to 4294967228, which is a overflow of
'4 - INT_H_SIZE - EMSG_OVERHEAD' in tipc_link_mss().
With tipc_link.mtu = 4, tipc_link_xmit() kept printing the warning:
tipc: Too large msg, purging xmit list 1 5 0 40 4!
tipc: Too large msg, purging xmit list 1 15 0 60 4!
And with tipc_link_entry.mtu 4294967228, a huge skb was allocated in
named_distribute(), and when purging it in tipc_link_xmit(), a crash
was even caused:

sdei_cpuhp_up() is called in the STARTING hotplug section,
which runs with interrupts disabled. Use a CPUHP_AP_ONLINE_DYN entry
instead to execute the cpuhp cb later, with preemption enabled.
SDEI originally got its own cpuhp slot to allow interacting
with perf. It got superseded by pNMI and this early slot is not
relevant anymore. [1]
Some SDEI calls (e.g. SDEI_1_0_FN_SDEI_PE_MASK) take actions on the
calling CPU. It is checked that preemption is disabled for them.
_ONLINE cpuhp cb are executed in the 'per CPU hotplug thread'.
Preemption is enabled in those threads, but their cpumask is limited
to 1 CPU.
Move 'WARN_ON_ONCE(preemptible())' statements so that SDEI cpuhp cb
don't trigger them.
Also add a check for the SDEI_1_0_FN_SDEI_PRIVATE_RESET SDEI call
which acts on the calling CPU.

[ Upstream commit 31088f6f79 ]
typeof is (still) a GNU extension, which means that it cannot be used when
building ISO C (e.g. -std=c99). It should therefore be avoided in uapi
headers in favour of the ISO-friendly __typeof__.
Unfortunately this issue could not be detected by
CONFIG_UAPI_HEADER_TEST=y as the __ALIGN_KERNEL() macro is not expanded in
any uapi header.
This matters from a userspace perspective, not a kernel one. uapi
headers and their contents are expected to be usable in a variety of
situations, and in particular when building ISO C applications (with
-std=c99 or similar).
This particular problem can be reproduced by trying to use the
__ALIGN_KERNEL macro directly in application code, say:
int align(int x, int a)
{
return __KERNEL_ALIGN(x, a);
}
and trying to build that with -std=c99.

commit 769fdf83df upstream.
When !SCHEDSTATS schedstat_enabled() is an unconditional 0 and the
whole block doesn't exist, however GCC figures the scoped variable
'stats' is unused and complains about it.
Upgrade the warning from -Wunused-variable to -Wunused-but-set-variable
by writing it in two statements. This fixes the build because the new
warning is in W=1.
Given that whole if(0) {} thing, I don't feel motivated to change
things overly much and quite strongly feel this is the compiler being
daft.

[ Upstream commit ceeadb83ae ]
If we want to use the schedstats facility to trace other sched classes, we
should make it independent of fair sched class. The struct sched_statistics
is the schedular statistics of a task_struct or a task_group. So we can
move it into struct task_struct and struct task_group to achieve the goal.
After the patch, schestats are orgnized as follows,
struct task_struct {
...
struct sched_entity se;
struct sched_rt_entity rt;
struct sched_dl_entity dl;
...
struct sched_statistics stats;
...
};
Regarding the task group, schedstats is only supported for fair group
sched, and a new struct sched_entity_stats is introduced, suggested by
Peter -
struct sched_entity_stats {
struct sched_entity se;
struct sched_statistics stats;
} __no_randomize_layout;
Then with the se in a task_group, we can easily get the stats.
The sched_statistics members may be frequently modified when schedstats is
enabled, in order to avoid impacting on random data which may in the same
cacheline with them, the struct sched_statistics is defined as cacheline
aligned.
As this patch changes the core struct of scheduler, so I verified the
performance it may impact on the scheduler with 'perf bench sched
pipe', suggested by Mel. Below is the result, in which all the values
are in usecs/op.
Before After
kernel.sched_schedstats=0 5.2~5.4 5.2~5.4
kernel.sched_schedstats=1 5.3~5.5 5.3~5.5
[These data is a little difference with the earlier version, that is
because my old test machine is destroyed so I have to use a new
different test machine.]
Almost no impact on the sched performance.
No functional change.

[ Upstream commit 5c5a7680e6 ]
struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
So this is an source for errors typically yielding resource leaks in the
error path.
As there are too many platform drivers to neatly convert them all to
return void in a single go, do it in several steps after this patch:
a) Convert all drivers to implement .remove_new() returning void instead
of .remove() returning int;
b) Change struct platform_driver::remove() to return void and so make
it identical to .remove_new();
c) Change all drivers back to .remove() now with the better prototype;
d) drop struct platform_driver::remove_new().
While this touches all drivers eventually twice, steps a) and c) can be

Over the lifetime of the kernel, new arm64 cpucaps need to be added to
handle errata and other fun stuff. So reserve 20 spots for us to use in
the future as this is an ABI-stable structure that we can not increase
over time without major problems.

Make this usable from pKVM by exposing two new kvm_pgtable_prot entries

Nothing currently prevents the donation of an MMIO region to the
hypervisor for backing e.g. guest stage-2 page-tables, tracing buffers,
hyp vm and vcpu metadata, or any other donation to EL2. However, the
only confirmed use-case for MMIO donations are for protecting the IOMMU
registers as well as for vendor module usage.
Restrict the donation of MMIO regions to these two paths only by
introducing a new helper function.

We've historically disallowed state changes for MMIO pages -- the host
had sole ownership of all of them. However, changing the state of those
pages has clearly become a goal both to support vendor extensions to
the hypervisor, as well as to support device assignment in the longer
term. To pave the way towards this support, let's allow certain state
transitions for MMIO pages.

There shouldn't be any reason to ever need allocating from the host
stage-2 pool during mem aborts now that the base page-table structure
is pinned. To prevent future regressions in this area, introduce a new
sanity check that will warn when hyp_page_alloc() is used from the mem
wrong paths.

The MMIO register space for IOMMUs controlled by the hypervisor is
currently unmapped from the host stage-2, and we rely on the host abort
path to not accidentally map them. However, this approach becomes
increasingly difficult to maintain as we introduce support for donating
MMIO regions and not just memory -- nothing prevents the host from
donating a protected MMIO register to another entity for example.
Now that MMIO donations are possible, let's use the proper
host-donate-hyp machinery to implement this. As a nice side effect, this
guarantees the host stage-2 page-table is annotated with hyp ownership
for those IOMMU regions, which guarantees the core range alignment
feature in the host mem abort parth will do the right thing without
requiring a second pass in the IOMMU code. This also turns the host
stage-2 PTEs into "non-default" entries, hence avoiding issues with the
coallescing code looking forward.

We're now guaranteed by construction to not require structural changes
to the host stage-2 page-table from the host memory abort path, so let's
use the low-level __host_stage2_idmap() function directly instead of the
higher-level wrapper that attempts page recycling when running out of
memory.

Now that the host stage-2 page-table is entirely pre-populated in
__pkvm_init_finalize(), we know that by the end of this function, the
structure of the page-table will remain stable until the host calls in
the hypervisor to require e.g. a page-table changes (by e.g. running a
guest). This does not necessarily mean that no host mem aborts will
occur -- there may be null PTEs in the host stage-2 due to collapsed
block mappings from fix_host_ownership() for example -- but all those
aborts should be trivially handled without requiring structural changes
to the page-table. This has the nice side effect of guaranteeing that
host_mem_abort() will not allocate from the host stage-2 pool. In order
to ensure this desirable property is retained for the lifetime of the
system even in the presence of the coalescing feature, let's 'pin' the
structure of the page-table as-is by taking an additional reference
from each table entry.

We will soon attempt to avoid any memory allocations from the host mem
abort path. In order to pave the way towards supporting this, let's
pre-populate the host stage-2 for the entire address space using as many
block mappings as possible. Some of these mappings may need to be
collapsed shortly after from fix_host_ownership() for example, so this
doesn't guarantee the absence of memory aborts altogether, but helps
getting the structure of the page-table in the right shape early on.

The fix_host_ownership() path walks the hypervisor's stage-1 page-table
to adjust the host's stage-2 accordingly. However, this is done before
the hyp stage-1 refcount has been fixed up, and before the hyp percpu
fixmap has been created. This all works right now as we start off with
an empty host stage-2, so none of the changes require the usage of the
fixmap for e.g. CMOs.
To prepare the ground for doing fix_host_ownership() with a non-empty
page-table, finalize the hyp stage-1 upfront.

The fuzzed image contains an AGF with an obviously garbage
agf_refcount_level value of 32, and a dirty log with a buffer log item
for that AGF. The ondisk AGF has a higher LSN than the recovered log
item. xlog_recover_buf_commit_pass2 reads the buffer, compares the
LSNs, and decides to skip replay because the ondisk buffer appears to be
newer.
Unfortunately, the ondisk buffer is corrupt, but recovery just read the
buffer with no buffer ops specified:
error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno,
buf_f->blf_len, buf_flags, &bp, NULL);
Skipping the buffer leaves its contents in memory unverified. This sets
us up for a kernel crash because xfs_refcount_recover_cow_leftovers
reads the buffer (which is still around in XBF_DONE state, so no read
verification) and creates a refcountbt cursor of height 32. This is
impossible so we run off the end of the cursor object and crash.
Fix this by invoking the verifier on all skipped buffers and aborting
log recovery if the ondisk buffer is corrupt. It might be smarter to
force replay the log item atop the buffer and then see if it'll pass the
write verifier (like ext4 does) but for now let's go with the
conservative option where we stop immediately.
