The caller of XDP_SETUP_PROG has already incremented refcnt in
__bpf_prog_get(), so drivers should only increment refcnt by
num_queues - 1.
To fix the issue, update netvsc_xdp_set() to add the correct number
to refcnt.
Hold a refcnt in netvsc_xdp_set()’s other caller, netvsc_attach().
And, do the same in netvsc_vf_setxdp(). Otherwise, every time when VF is
removed and added from the host side, the refcnt will be decreased by one,
which may cause page fault when unloading xdp program.

taprio: Some fixes
Changes from v3:
- Replaced ENOTSUPP error code with EOPNOTSUPP (Jakub Kicinski);
- Added the missing policy validation for the flags netlink argument
(Jakub Kicinski);
- Fixed the destroy() flow to also destroy the priority to traffic
class mapping (David Miller);
- Fixed dropping packets when taprio offloading is used together
with ETF offloading (more on this below);
Changes from v2:
- Squashed commits 2/3 and 3/3 into a single one (I think a single
commit is going to be easier to review);
- Removed an "improvement" that was causing changes in user visible
behavior;
Changes from v1:
- Fixed ignoring the 'flags' argument when adding a new
instance (Vladimir Oltean);
- Changed the order of commits;
Updated cover letter:
One bit that might need some attention is the fix for not dropping all
packets when taprio and ETF offloading are used, patch 5/5. The
behavior when the fix is applied is that packets that have a 'txtime'
that would fall outside of their transmission window are now dropped
by taprio. The question that might be raised is: should taprio be
responsible for dropping these packets, or should it be handled lower
in the stack?
My opinion is: taprio has all the information, and it's able to give
feeback to the user. Lower in the stack, those packets might go into
the void, and the only feedback could be a hard to find counter
increasing.
Patch 1/5: Reported by Po Liu, is more of a improvement of usability for
drivers implementing offloading features, now they can rely on the
value of dev->num_tc, instead of going through some hops to get this
value.
Patch 2/5: Use 'q->flags' as the source of truth for the offloading
flags. Tries to solidify the current behavior, while avoiding going
into invalid states, one of which was causing a "rcu stall" (more
information in the commit message).
Patch 3/5: Adds the missing netlink attribute validation for
TCA_TAPRIO_ATTR_FLAGS.
Patch 4/5: Replaces the usage of netdev_set_num_tc() with
netdev_reset_tc() in taprio_destroy(), taprio_destroy() is called when
applying a configuration fails, making sure that the device traffic
class configuration goes back to the default state.
@Vladimir: If possible, I would appreciate your Ack on patch 2/5. I
have been looking at this code for so long that I might have missed
something obvious (and my growing dislike for the word 'flags' may be
affecting my judgement :-).

When using taprio offloading together with ETF offloading, configured
like this, for example:
$ tc qdisc replace dev $IFACE parent root handle 100 taprio \
num_tc 4 \
map 2 2 1 0 3 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 1@2 1@3 \
base-time $BASE_TIME \
sched-entry S 01 1000000 \
sched-entry S 0e 1000000 \
flags 0x2
$ tc qdisc replace dev $IFACE parent 100:1 etf \
offload delta 300000 clockid CLOCK_TAI
During enqueue, it works out that the verification added for the
"txtime" assisted mode is run when using taprio + ETF offloading, the
only thing missing is initializing the 'next_txtime' of all the cycle
entries. (if we don't set 'next_txtime' all packets from SO_TXTIME
sockets are dropped)

When destroying the current taprio instance, which can happen when the
creation of one fails, we should reset the traffic class configuration
back to the default state.
netdev_reset_tc() is a better way because in addition to setting the
number of traffic classes to zero, it also resets the priority to
traffic classes mapping to the default value.

If the driver implementing taprio offloading depends on the value of
the network device number of traffic classes (dev->num_tc) for
whatever reason, it was going to receive the value zero. The value was
only set after the offloading function is called.
So, moving setting the number of traffic classes to before the
offloading function is called fixes this issue. This is safe because
this only happens when taprio is instantiated (we don't allow this
configuration to be changed without first removing taprio).

rxrpc_rcu_destroy_call(), which is called as an RCU callback to clean up a
put call, calls rxrpc_put_connection() which, deep in its bowels, takes a
number of spinlocks in a non-BH-safe way, including rxrpc_conn_id_lock and
local->client_conns_lock. RCU callbacks, however, are normally called from
softirq context, which can cause lockdep to notice the locking
inconsistency.
To get lockdep to detect this, it's necessary to have the connection
cleaned up on the put at the end of the last of its calls, though normally
the clean up is deferred. This can be induced, however, by starting a call
on an AF_RXRPC socket and then closing the socket without reading the
reply.
Fix this by having rxrpc_rcu_destroy_call() punt the destruction to a
workqueue if in softirq-mode and defer the destruction to process context.
Note that another way to fix this could be to add a bunch of bh-disable
annotations to the spinlocks concerned - and there might be more than just
those two - but that means spending more time with BHs disabled.
Note also that some of these places were covered by bh-disable spinlocks
belonging to the rxrpc_transport object, but these got removed without the
_bh annotation being retained on the next lock in.

The recent patch that substituted a flag on an rxrpc_call for the
connection pointer being NULL as an indication that a call was disconnected
puts the set_bit in the wrong place for service calls. This is only a
problem if a call is implicitly terminated by a new call coming in on the
same connection channel instead of a terminating ACK packet.
In such a case, rxrpc_input_implicit_end_call() calls
__rxrpc_disconnect_call(), which is now (incorrectly) setting the
disconnection bit, meaning that when rxrpc_release_call() is later called,
it doesn't call rxrpc_disconnect_call() and so the call isn't removed from
the peer's error distribution list and the list gets corrupted.
KASAN finds the issue as an access after release on a call, but the
position at which it occurs is confusing as it appears to be related to a
different call (the call site is where the latter call is being removed
from the error distribution list and either the next or pprev pointer
points to a previously released call).
Fix this by moving the setting of the flag from __rxrpc_disconnect_call()
to rxrpc_disconnect_call() in the same place that the connection pointer
was being cleared.

As it is, vfs_parse_fs_string() makes "foo" and "foo=" indistinguishable;
both get fs_value_is_string for ->type and NULL for ->string. To make
it even more unpleasant, that combination is impossible to produce with
fsconfig().
Much saner rules would be
"foo" => fs_value_is_flag, NULL
"foo=" => fs_value_is_string, ""
"foo=bar" => fs_value_is_string, "bar"
All cases are distinguishable, all results are expressable by fsconfig(),
->has_value checks are much simpler that way (to the point of the field
being useless) and quite a few regressions go away (gfs2 has no business
accepting -o nodebug=, for example).

For a cyclic work queue, when not requesting a completion per WQE,
a single CQE might indicate the completion of several WQEs.
However, in case some WQE in the batch causes an error, then an error
completion is issued, breaking the batch, and pointing to the offending
WQE in the wqe_counter field.
Hence, WQE-specific error CQE handling (like printing, breaking, etc...)
should be performed only for the last WQE in batch.

This partially reverts the DMA API support that was recently merged
because it was causing performance regressions on older Tegra devices.
Unfortunately, the cache maintenance performed by dma_map_sg() and
dma_unmap_sg() causes performance to drop by a factor of 10.
The right solution for this would be to cache mappings for buffers per
consumer device, but that's a bit involved. Instead, we simply revert to
the old behaviour of sharing IOVA mappings when we know that devices can
do so (i.e. they share the same IOMMU domain).

regressions on some platforms (it was reported for sparc64).
This pull request fixes it with a direct revert.

When the first log header in a journal happens to have a sequence
number of 0, a bug in gfs2_find_jhead() causes it to prematurely exit,
and return an uninitialized jhead with seq 0. This can cause failures
in the caller. For instance, a mount fails in one test case.
The correct behavior is for it to continue searching through the journal
to find the correct journal head with the highest sequence number.

Handle the special case of fuse_readpages() wanting to read the last page
of a hugest file possible and overflowing the end offset in the process.
This is basically to unbreak xfstests:generic/525 and prevent filesystems
from doing bad things with an overflowing offset.

fuse_direct_io() can end up advancing the iterator by more than the amount
of data read or written. This case is handled by the generic code if going
through ->direct_IO(), but not in the FOPEN_DIRECT_IO case.
Fix by reverting the extra bytes from the iterator in case of error or a
short count.
To test: install lxcfs, then the following testcase
int fd = open("/var/lib/lxcfs/proc/uptime", O_RDONLY);
sendfile(1, fd, NULL, 16777216);
sendfile(1, fd, NULL, 16777216);
will spew WARN_ON() in iov_iter_pipe().

After a number of suspend and resume cycles, it is possible for the RBUF
to be stuck in Wake-on-LAN mode, despite the MPD enable bit being
cleared which instructed the RBUF to exit that mode.
Avoid creating that problematic condition by clearing the RX_EN and
TX_EN bits in the UniMAC prior to disable the Magic Packet Detector
logic which is guaranteed to make the RBUF exit Wake-on-LAN mode.
