Now that a client can have multiple xprts, we need to add
them all to debugs.
The first one is still "xprt"
Subsequent xprts are "xprt1", "xprt2", etc.

We often see various error conditions with NFS4.x that show up with
a very high operation count all completing with tk_status < 0 in a
short period of time. Add a count to rpc_iostats to record on a
per-op basis the ops that complete in this manner, which will
enable lower overhead diagnostics.

For diagnostic purposes, it would be useful to have an rpc_iostats
metric of RPCs completing with tk_status < 0. Unfortunately,
tk_status is reset inside the rpc_call_done functions for each
operation, and the call to tally the per-op metrics comes after
rpc_call_done. Refactor the call to rpc_count_iostat earlier in
rpc_exit_task so we can count these RPCs completing in error.

With NFSv4.1, different network connections need to be explicitly
bound to a session. During session startup, this is not possible
so only a single connection must be used for session startup.
So add a task flag to disable the default round-robin choice of
connections (when nconnect > 1) and force the use of a single
connection.
Then use that flag on all requests for session management - for
consistence, include NFSv4.0 management (SETCLIENTID) and session
destruction

The queue timer function, which walks the RPC queue in order to locate
candidates for waking up is one of the current constraints against
removing the bh-safe queue spin locks. Replace it with a delayed
work queue, so that we can do the actual rpc task wake ups from an
ordinary process context.

Problem: The Linux Bluetooth stack yields complete control over the BLE
connection interval to the remote device.
The Linux Bluetooth stack provides access to the BLE connection interval
min and max values through /sys/kernel/debug/bluetooth/hci0/
conn_min_interval and /sys/kernel/debug/bluetooth/hci0/conn_max_interval.
These values are used for initial BLE connections, but the remote device
has the ability to request a connection parameter update. In the event
that the remote side requests to change the connection interval, the Linux
kernel currently only validates that the desired value is within the
acceptable range in the Bluetooth specification (6 - 3200, corresponding to
7.5ms - 4000ms). There is currently no validation that the desired value
requested by the remote device is within the min/max limits specified in
the conn_min_interval/conn_max_interval configurations. This essentially
leads to Linux yielding complete control over the connection interval to
the remote device.
The proposed patch adds a verification step to the connection parameter
update mechanism, ensuring that the desired value is within the min/max
bounds of the current connection. If the desired value is outside of the
current connection min/max values, then the connection parameter update
request is rejected and the negative response is returned to the remote
device. Recall that the initial connection is established using the local
conn_min_interval/conn_max_interval values, so this allows the Linux
administrator to retain control over the BLE connection interval.
The one downside that I see is that the current default Linux values for
conn_min_interval and conn_max_interval typically correspond to 30ms and
50ms respectively. If this change were accepted, then it is feasible that
some devices would no longer be able to negotiate to their desired
connection interval values. This might be remedied by setting the default
Linux conn_min_interval and conn_max_interval values to the widest
supported range (6 - 3200 / 7.5ms - 4000ms). This could lead to the same
behavior as the current implementation, where the remote device could
request to change the connection interval value to any value that is
permitted by the Bluetooth specification, and Linux would accept the
desired value.

Because of both sides doing L2CAP disconnection at the same time, it
was possible to receive L2CAP Disconnection Response with CID that was
already freed. That caused problems if CID was already reused and L2CAP
Connection Request with same CID was sent out. Before this patch kernel
deleted channel context regardless of the state of the channel.
Example where leftover Disconnection Response (frame #402) causes local
device to delete L2CAP channel which was not yet connected. This in
turn confuses remote device's stack because same CID is re-used without
properly disconnecting.

This change is similar to commit a1616a5ac99e ("Bluetooth: hidp: fix
buffer overflow") but for the compat ioctl. We take a string from the
user and forgot to ensure that it's NUL terminated.
I have also changed the strncpy() in to strscpy() in hidp_setup_hid().
The difference is the strncpy() doesn't necessarily NUL terminate the
destination string. Either change would fix the problem but it's nice
to take a belt and suspenders approach and do both.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
Because we don't care if debugfs works or not, this trickles back a bit
so we can clean things up by making some functions return void instead
of an error value that is never going to fail.

Both ip_neigh_gw4() and ip_neigh_gw6() can return either a valid pointer
or an error pointer, but the code currently checks that the pointer is
not NULL.
Fix this by checking that the pointer is not an error pointer, as this
can result in a NULL pointer dereference [1]. Specifically, I believe
that what happened is that ip_neigh_gw4() returned '-EINVAL'
(0xffffffffffffffea) to which the offset of 'refcnt' (0x70) was added,
which resulted in the address 0x000000000000005a.

hsr_link_ops implements ->newlink() but not ->dellink(),
which leads that resources not released after removing the device,
particularly the entries in self_node_db and node_db.
So add ->dellink() implementation to replace the priv_destructor.
This also makes the code slightly easier to understand.

hsr_del_port() should release all the resources allocated
in hsr_add_port().
As a consequence of this change, hsr_for_each_port() is no
longer safe to work with hsr_del_port(), switch to
list_for_each_entry_safe() as we always hold RTNL lock.

pull-request: bpf-next 2019-07-03
The following pull-request contains BPF updates for your *net-next* tree.
There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim:
Rename externally used net_dim members") which has been pulled into your
tree in the meantime, but resolution seems not that bad ... getting current
bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed
just so he's aware of the resolution below:
** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
static int mlx5e_open_cq(struct mlx5e_channel *c,
struct dim_cq_moder moder,
struct mlx5e_cq_param *param,
struct mlx5e_cq *cq)
=======
int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder,
struct mlx5e_cq_param *param, struct mlx5e_cq *cq)
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Resolution is to take the second chunk and rename net_dim_cq_moder into
dim_cq_moder. Also the signature for mlx5e_open_cq() in ...
drivers/net/ethernet/mellanox/mlx5/core/en.h +977
... and in mlx5e_open_xsk() ...
drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64
... needs the same rename from net_dim_cq_moder into dim_cq_moder.
** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix));
struct dim_cq_moder icocq_moder = {0, 0};
struct net_device *netdev = priv->netdev;
struct mlx5e_channel *c;
unsigned int irq;
=======
struct net_dim_cq_moder icocq_moder = {0, 0};
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Take the second chunk and rename net_dim_cq_moder into dim_cq_moder
as well.
Let me know if you run into any issues. Anyway, the main changes are:
1) Long-awaited AF_XDP support for mlx5e driver, from Maxim.
2) Addition of two new per-cgroup BPF hooks for getsockopt and
setsockopt along with a new sockopt program type which allows more
fine-grained pass/reject settings for containers. Also add a sock_ops
callback that can be selectively enabled on a per-socket basis and is
executed for every RTT to help tracking TCP statistics, both features
from Stanislav.
3) Follow-up fix from loops in precision tracking which was not propagating
precision marks and as a result verifier assumed that some branches were
not taken and therefore wrongly removed as dead code, from Alexei.
4) Fix BPF cgroup release synchronization race which could lead to a
double-free if a leaf's cgroup_bpf object is released and a new BPF
program is attached to the one of ancestor cgroups in parallel, from Roman.
5) Support for bulking XDP_TX on veth devices which improves performance
in some cases by around 9%, from Toshiaki.
6) Allow for lookups into BPF devmap and improve feedback when calling into
bpf_redirect_map() as lookup is now performed right away in the helper
itself, from Toke.
7) Add support for fq's Earliest Departure Time to the Host Bandwidth
Manager (HBM) sample BPF program, from Lawrence.
8) Various cleanups and minor fixes all over the place from many others.
