This enables tracking ion memory utilization changes, as well as
individual buffer allocations.
This was inspired by the pixel kernel patches by timmurray@ and
carmenjackson@.

A recent update of libabigail introduces some more tracking options
(ELF variable sizes, aliased symbols, CRC values). Unfortunately this is
incompatible with the current representation. Hence update.
The update introduces new CRC values and corrects the symbol lists to
contain only symbols that are part of the ksymtab.
The symbols of the modules are now listed along with the symbols of
vmlinux. That is a benign flaw that does not harm analysis and will be
corrected later.

The entire implementation is in kernel/bpf/helpers.c:
BPF_CALL_0(bpf_ktime_get_ns) {
/* NMI safe access to clock monotonic */
return ktime_get_mono_fast_ns();
}
const struct bpf_func_proto bpf_ktime_get_ns_proto = {
.func = bpf_ktime_get_ns,
.gpl_only = false,
.ret_type = RET_INTEGER,
};
and this was presumably marked GPL due to kernel/time/timekeeping.c:
EXPORT_SYMBOL_GPL(ktime_get_mono_fast_ns);
and while that may make sense for kernel modules (although even that
is doubtful), there is currently AFAICT no other source of time
available to ebpf.
Furthermore this is really just equivalent to clock_gettime(CLOCK_MONOTONIC)
which is exposed to userspace (via vdso even to make it performant)...
As such, I see no reason to keep the GPL restriction.
(In the future I'd like to have access to time from Apache licensed ebpf code)

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

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.

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.

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.

@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.

commit 097350d1c6e1f5808cae142006f18a0bbc57018d upstream.
Currently the ring buffer makes events that happen in interrupts that preempt
another event have a delta of zero. (Hopefully we can change this soon). But
this is to deal with the races of updating a global counter with lockless
and nesting functions updating deltas.
With the addition of absolute time stamps, the time extend didn't follow
this rule. A time extend can happen if two events happen longer than 2^27
nanoseconds appart, as the delta time field in each event is only 27 bits.
If that happens, then a time extend is injected with 2^59 bits of
nanoseconds to use (18 years). But if the 2^27 nanoseconds happen between
two events, and as it is writing the event, an interrupt triggers, it will
see the 2^27 difference as well and inject a time extend of its own. But a
recent change made the time extend logic not take into account the nesting,
and this can cause two time extend deltas to happen moving the time stamp
much further ahead than the current time. This gets all reset when the ring
buffer moves to the next page, but that can cause time to appear to go
backwards.
This was observed in a trace-cmd recording, and since the data is saved in a
file, with trace-cmd report --debug, it was possible to see that this indeed
did happen!

For example, these return -EINVAL
echo " traceon" > events/ftrace/print/trigger
echo "traceon if common_pid == 0" > events/ftrace/print/trigger
echo "disable_event:kmem:kmalloc " > events/ftrace/print/trigger
But these are hard to find what is wrong.
To fix this issue, use skip_spaces() to remove spaces
in front of actual tokens, and set NULL if there is no
token.

In the ocfs2 disk layout, slot number is 16 bits, but in ocfs2
implementation, slot number is 32 bits. Usually this will not cause any
issue, because slot number is converted from u16 to u32, but
OCFS2_INVALID_SLOT was defined as -1, when an invalid slot number from
disk was obtained, its value was (u16)-1, and it was converted to u32.
Then the following checking in get_local_system_inode will be always
skipped:
static struct inode **get_local_system_inode(struct ocfs2_super *osb,
int type,
u32 slot)
{
BUG_ON(slot == OCFS2_INVALID_SLOT);
