BPF programs may want to know whether an skb is gso. The canonical
answer is skb_is_gso(skb), which tests that gso_size != 0.
Expose this field in the same manner as gso_segs. That field itself
is not a sufficient signal, as the comment in skb_shared_info makes
clear: gso_segs may be zero, e.g., from dodgy sources.
Also prepare net/bpf/test_run for upcoming BPF_PROG_TEST_RUN tests
of the feature.

SMMU fault is observed due to spurious AXI transaction even after
gcc video_axi clocks are disabled. HW underlying may not actually turn off
clocks since HW enable signals can still be asserted/waiting on certain
scenarios like when CVP and MVP both are power collapsed.
Use clk_branch2_force_off_ops to guarantee that clocks are actually
turned off when SW disables them.

When SDHC gets reset (E.g. in runtime suspend path), CQE also gets
reset and goes to disable state. But s/w state still points it as CQE
is in enabled state. Since s/w and h/w states go out of sync,
it results in s/w request timeout for subsequent CQE requests.
To synchronize CQE s/w and h/w state during SDHC reset,
explicitly deactivate CQE just before SDHC reset.

If a controller supports RDDM, there is no need to process a SYS_ERROR.
Hence, we can safely move the power down state check to reside within an
RDDM supported controller as it allows for other controllers to handle
scenarios such as receiving an early SYS_ERROR when in the PBL execution
environment.

As of now, there is no way for MHI to know if device supports RDDM
and host controller wishes to skip ramdump collection. Allow for
that by letting the controller set the rddm support boolean which
indicates device side support. If rddm_size is set to zero while
the support for RDDM is present, that indicates disinterest in
ramdump collection if RDDM execution environment is entered.

When the command was switched over from 'lz4c' to 'lz4', it changed the
meaning of '-c' in a subtle way. In the older lz4c tool, this '-cX'
seems to be a different flag, meaning the compression level. In the
newer lz4 tool, it means to compress to stdout. However, since kbuild
already specifies stdout as a file name, '-c' is superfluous, and
generates a warning:
Warning : stdout won't be used ! Do you want multiple input files (-m) ?
Fix it by removing the extra stdout flag.

[ Upstream commit d0c7feaf87678371c2c09b3709400be416b2dc62 ]
We recently used fuzz(hydra) to test XFS and automatically generate
tmp.img(XFS v5 format, but some metadata is wrong)
xfs_repair information(just one AG):
agf_freeblks 0, counted 3224 in ag 0
agf_longest 536874136, counted 3224 in ag 0
sb_fdblocks 613, counted 3228
Test as follows:
mount tmp.img tmpdir
cp file1M tmpdir
sync
In 4.19-stable, sync will stuck, the reason is:
xfs_mountfs
xfs_check_summary_counts
if ((!xfs_sb_version_haslazysbcount(&mp->m_sb) ||
XFS_LAST_UNMOUNT_WAS_CLEAN(mp)) &&
!xfs_fs_has_sickness(mp, XFS_SICK_FS_COUNTERS))
return 0; -->just return, incore sb_fdblocks still be 613
xfs_initialize_perag_data
cp file1M tmpdir -->ok(write file to pagecache)
sync -->stuck(write pagecache to disk)
xfs_map_blocks
xfs_iomap_write_allocate
while (count_fsb != 0) {
nimaps = 0;
while (nimaps == 0) { --> endless loop
nimaps = 1;
xfs_bmapi_write(..., &nimaps) --> nimaps becomes 0 again
xfs_bmapi_write
xfs_bmap_alloc
xfs_bmap_btalloc
xfs_alloc_vextent
xfs_alloc_fix_freelist
xfs_alloc_space_available -->fail(agf_freeblks is 0)
In linux-next, sync not stuck, cause commit c2b3164320 ("xfs:
use the latest extent at writeback delalloc conversion time") remove
the above while, dmesg is as follows:
[ 55.250114] XFS (loop0): page discard on page ffffea0008bc7380, inode 0x1b0c, offset 0.
Users do not know why this page is discard, the better soultion is:
1. Like xfs_repair, make sure sb_fdblocks is equal to counted
(xfs_initialize_perag_data did this, who is not called at this mount)
2. Add agf verify, if fail, will tell users to repair
This patch use the second soultion.

Add cond_resched() to a loop that fills in the mapper memory area
because the loop can be executed many times.

commit 7b2182ec381f8ea15c7eb1266d6b5d7da620ad93 upstream.
The RPC client currently doesn't handle ERR_CHUNK replies correctly.
rpcrdma_complete_rqst() incorrectly passes a negative number to
xprt_complete_rqst() as the number of bytes copied. Instead, set
task->tk_status to the error value, and return zero bytes copied.
In these cases, return -EIO rather than -EREMOTEIO. The RPC client's
finite state machine doesn't know what to do with -EREMOTEIO.
Additional clean ups:
- Don't double-count RDMA_ERROR replies
- Remove a stale comment

commit d03727b248d0dae6199569a8d7b629a681154633 upstream.
Figuring out the root case for the REMOVE/CLOSE race and
suggesting the solution was done by Neil Brown.
Currently what happens is that direct IO calls hold a reference
on the open context which is decremented as an asynchronous task
in the nfs_direct_complete(). Before reference is decremented,
control is returned to the application which is free to close the
file. When close is being processed, it decrements its reference
on the open_context but since directIO still holds one, it doesn't
sent a close on the wire. It returns control to the application
which is free to do other operations. For instance, it can delete a
file. Direct IO is finally releasing its reference and triggering
an asynchronous close. Which races with the REMOVE. On the server,
REMOVE can be processed before the CLOSE, failing the REMOVE with
EACCES as the file is still opened.

If the mirror count changes in the new layout we pick up inside
ff_layout_pg_init_write(), then we can end up adding the
request to the wrong mirror and corrupting the mirror->pg_list.

commit 89a3c9f5b9f0bcaa9aea3e8b2a616fcaea9aad78 upstream.
@subbuf is an output parameter of xdr_buf_subsegment(). A survey of
call sites shows that @subbuf is always uninitialized before
xdr_buf_segment() is invoked by callers.
There are some execution paths through xdr_buf_subsegment() that do
not set all of the fields in @subbuf, leaving some pointer fields
containing garbage addresses. Subsequent processing of that buffer
then results in a page fault.
