staging: lustre: lmv: correctly iput lmo_root
Commit
8f18c8a48b73 ("staging: lustre: lmv: separate master object
with master stripe") changed how lmo_root inodes were managed,
particularly when LMV_HASH_FLAG_MIGRATION is not set.
Previously lsm_md_oinfo[0].lmo_root was always a borrowed
inode reference and didn't need to by iput().
Since the change, that special case only applies when
LMV_HASH_FLAG_MIGRATION is set
In the upstream (lustre-release) version of this patch [Commit
60e07b972114 ("LU-4690 lod: separate master object with master
stripe")] the for loop in the lmv_unpack_md() was changed to count
from 0 and to ignore entry 0 if LMV_HASH_FLAG_MIGRATION is set.
In the patch that got applied to Linux, that change was missing,
so lsm_md_oinfo[0].lmo_root is never iput().
This results in a "VFS: Busy inodes" warning at unmount.

staging: lustre: lov: use correct env in lov_io_data_version_end()
lov - the logical object volume manager - is responsible for
striping data across multiple volumes.
So when it is given a request, it creates one or more
sub-requests, one for each target volume. Each sub_io
request has a sub_env environment which it operates in.
When lov_io_data_version_end() calls lov_io_end_wrapper() to
wait for and close off a sub_io, it passes the wrong
environment.
This causes an LINVRNT() to fail in cl2osc_io(), and may
cause other problems.
This patch changes the call to use ->sub_env, much like
other code in the same file.

Lastly there is a deadlock fix around runtime suspend for secondary

There was a deadlock between one thread trying to wait for a workqueue
job to finish in the runtime suspend path, and the workqueue job it

The fixes avoids it by not doing the runtime sync in the workqueue as
then we always wait for all those tasks to complete before we runtime

net_sched: gen_estimator: fix broken estimators based on percpu stats
pfifo_fast got percpu stats lately, uncovering a bug I introduced last
year in linux-4.10.
I missed the fact that we have to clear our temporary storage
before calling __gnet_stats_copy_basic() in the case of percpu stats.
Without this fix, rate estimators (tc qd replace dev xxx root est 1sec
4sec pfifo_fast) are utterly broken.

gianfar: simplify FCS handling and fix memory leak
Previously, buffer descriptors containing only the frame check sequence
(FCS) were skipped and not added to the skb. However, the page reference
count was still incremented, leading to a memory leak.
Fixing this inside gfar_add_rx_frag() is difficult due to reserved
memory handling and page reuse. Instead, move the FCS handling to
gfar_process_frame() and trim off the FCS before passing the skb up the
networking stack.

ipv6 sit: work around bogus gcc-8 -Wrestrict warning
gcc-8 has a new warning that detects overlapping input and output arguments
in memcpy(). It triggers for sit_init_net() calling ipip6_tunnel_clone_6rd(),
which is actually correct:
net/ipv6/sit.c: In function 'sit_init_net':
net/ipv6/sit.c:192:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict]
The problem here is that the logic detecting the memcpy() arguments finds them
to be the same, but the conditional that tests for the input and output of
ipip6_tunnel_clone_6rd() to be identical is not a compile-time constant.
We know that netdev_priv(t->dev) is the same as t for a tunnel device,
and comparing "dev" directly here lets the compiler figure out as well
that 'dev == sitn->fb_tunnel_dev' when called from sit_init_net(), so
it no longer warns.
This code is old, so Cc stable to make sure that we don't get the warning
for older kernels built with new gcc.

Commit
d02fd6e7d293 ("macvlan: Fix one possible double free") handles
the case when register_netdevice() invokes ndo_uninit() on error and
as a result free the port. But 'macvlan_port_get_rtnl(dev))' check
(returns dev->rx_handler_data), which was added by this commit in order
to prevent double free, is not quite correct:
* for macvlan it always returns NULL because 'lowerdev' is the one that
was used to register rx handler (port) in macvlan_port_create() as
well as to unregister it in macvlan_port_destroy().
* for macvtap it always returns a valid pointer because macvtap registers
its own rx handler before macvlan_common_newlink().

arm64: fix unwind_frame() for filtered out fn for function graph tracing
do_task_stat() calls get_wchan(), which further does unwind_frame().
unwind_frame() restores frame->pc to original value in case function
graph tracer has modified a return address (LR) in a stack frame to hook
a function return. However, if function graph tracer has hit a filtered
function, then we can't unwind it as ftrace_push_return_trace() has
biased the index(frame->graph) with a 'huge negative'
offset(-FTRACE_NOTRACE_DEPTH).
Moreover, arm64 stack walker defines index(frame->graph) as unsigned
int, which can not compare a -ve number.
Similar problem we can have with calling of walk_stackframe() from
save_stack_trace_tsk() or dump_backtrace().
This patch fixes unwind_frame() to test the index for -ve value and
restore index accordingly before we can restore frame->pc.
Reproducer:
cd /sys/kernel/debug/tracing/
echo schedule > set_graph_notrace
echo 1 > options/display-graph
echo wakeup > current_tracer
ps -ef | grep -i agent
