Removing VF driver during device still in reset caused guest OS panic.
in the i40evf_remove(), we're trying to clean mac_filter_list which has
not been initialized since the device is still stuck at the reset.
The change is to initialize the filter_list before setting any task.

If the driver is loaded and then unloaded before the interface is
brought up, then it will allocate a MAC filter entry and never free it.
To fix this, on unload, run through the mac filter list and free all the
entries. We also do this during reset recovery when the driver cannot
contact the PF and needs to shut down completely.

Fix a memory leak. Driver was allocating memory for queue vectors on
init but not freeing them on shutdown. These need to be freed at two
different times: during module unload, and during reset recovery when
the driver cannot contact the PF driver and needs to give up.

Remove the ability of a VF to set unicast promiscuous mode.
Considered to be a security risk to allow VFs to receive traffic
intended for other VFs so don't allow it, simply ignore the flag.

be too short if a connection is not present. Increase the number of
retries and the sleep to give a bit more time. Also, change level of

clean up names related to socket filtering and bpf in the following way:
- everything that deals with sockets keeps 'sk_*' prefix
- everything that is pure BPF is changed to 'bpf_*' prefix
split 'struct sk_filter' into
struct sk_filter {
atomic_t refcnt;
struct rcu_head rcu;
struct bpf_prog *prog;
};
and
struct bpf_prog {
u32 jited:1,
len:31;
struct sock_fprog_kern *orig_prog;
unsigned int (*bpf_func)(const struct sk_buff *skb,
const struct bpf_insn *filter);
union {
struct sock_filter insns[0];
struct bpf_insn insnsi[0];
struct work_struct work;
};
};
so that 'struct bpf_prog' can be used independent of sockets and cleans up
'unattached' bpf use cases
split SK_RUN_FILTER macro into:
SK_RUN_FILTER to be used with 'struct sk_filter *' and
BPF_PROG_RUN to be used with 'struct bpf_prog *'
__sk_filter_release(struct sk_filter *) gains
__bpf_prog_release(struct bpf_prog *) helper function
also perform related renames for the functions that work
with 'struct bpf_prog *', since they're on the same lines:
sk_filter_size -> bpf_prog_size
sk_filter_select_runtime -> bpf_prog_select_runtime
sk_filter_free -> bpf_prog_free
sk_unattached_filter_create -> bpf_prog_create
sk_unattached_filter_destroy -> bpf_prog_destroy
sk_store_orig_filter -> bpf_prog_store_orig_filter
sk_release_orig_filter -> bpf_release_orig_filter
__sk_migrate_filter -> bpf_migrate_filter
__sk_prepare_filter -> bpf_prepare_filter
API for attaching classic BPF to a socket stays the same:
sk_attach_filter(prog, struct sock *)/sk_detach_filter(struct sock *)
and SK_RUN_FILTER(struct sk_filter *, ctx) to execute a program
which is used by sockets, tun, af_packet
API for 'unattached' BPF programs becomes:
bpf_prog_create(struct bpf_prog **)/bpf_prog_destroy(struct bpf_prog *)
and BPF_PROG_RUN(struct bpf_prog *, ctx) to execute a program
which is used by isdn, ppp, team, seccomp, ptp, xt_bpf, cls_bpf, test_bpf

1) We don't allocate enough space for the NUL terminator so we end up
corrupting one character beyond the end of the buffer.
2) The "len - 1" should just be "len". The code is trying to copy a
word from a buffer up to a comma or the last word in the buffer.
Say you have the buffer, "foo,bar,baz", then this code truncates the
last letter off each word so you get "fo", "ba", and "ba". You would
hope this kind of bug would get noticed in testing...
I'm not very familiar with this code and I can't test it, but I think
we should copy the final character.

This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case #8000684337 and shared with the maintainer.

This patch removes the check for the number of mulitcast addresses
when using hash based filtering since it's not necessary. If the number
of multicast addresses in the list exceeds the number of multicast hash
bins, the bins will "fold" over into one of the bins configured and
enabled for the particular component instance.
The default number of maximum unicast addresses was changed from 32 to 1
since this number is not dependent on the component revision. The maximum
number of multicast and unicast addresses is dependent on the configuration
of the Synopsys EMAC configured by the SOC architect at the time the
features were selected and configured for a particular component. Sadly,
Synopsys does not provide a way to query the precise number supported
by a particular component, so we must fall back on a devicetree entry.
This configuration could vary from vendor to vendor (such as STMicro,
Altera, etc).
The multicast bins are set for every possible filtering case (including
no entries) - previously the bits were set only if multicast filter entries
were present.

The synopsys EMAC can be configured for different numbers of multicast hash
bins and perfect filter entries at device creation time and there's no way
to query this configuration information at runtime. As a result, a devicetree
parameter is required in order for the driver to program these filters
correctly for a particular device instance. This patch modifies the
10/100/1000 MAC software interface such that these configuration parameters
can be set at initialization time.

Before that commit orig_fp was only destroyed in the same
block where it was assigned a valid BPF prog before. Fix it
up by initializing it to NULL.

The Micrel ksz9021 PHY does not support standard IEEE standard MMD
extended register access, therefore requires stubs to fail the read
register method and do nothing for the write register method when
libphy attempts to read and/or configure Energy Efficient Ethernet
features in PHYS that do support those features. This problem
was observed on an Altera Cyclone V SOC development kit that
uses the Synopsys EMAC and the Micrel ksz9021 PHY. This patch
was tested on the same board, and Energy Efficient Ethernet is
now disabled as expected since the Micrel PHY does not support that
feature.

libphy was originally written assuming all phy devices support clause 45
access extensions to the mmd registers through the indirection registers
located within the first 16 phy registers. This assumption is not true
in all cases, and one specific example is the Micrel ksz9021 10/100/1000
Mbps phy. Using the stmmac driver, accessing the mmd registers to query
and configure energy efficient Ethernet (EEE) features yielded unexpected
behavior.
This patch adds mmd access functions to the phy driver that can be
overriden by the phy specific driver if the phy does not support this
mechanism or uses it's own non-standard access mechanism. By default,
the IEEE Compatible clause 45 access mechanism described in clause 22
is used. With this patch, EEE query/configure functions as expected
using the stmmac and the Micrel ksz9021 phy.

sk_unattached_filter_destroy() does not always need to release the
filter object via rcu. Since this filter is never attached to the
socket, the caller should be responsible for releasing the filter
in a safe way, which may not necessarily imply rcu.
This is a short summary of clients of this function:
1) xt_bpf.c and cls_bpf.c use the bpf matchers from rules, these rules
are removed from the packet path before the filter is released. Thus,
the framework makes sure the filter is safely removed.
2) In the ppp driver, the ppp_lock ensures serialization between the
xmit and filter attachment/detachment path. This doesn't use rcu
so deferred release via rcu makes no sense.
3) In the isdn/ppp driver, it is called from isdn_ppp_release()
the isdn_ppp_ioctl(). This driver uses mutex and spinlocks, no rcu.
Thus, deferred rcu makes no sense to me either, the deferred releases
may be just masking the effects of wrong locking strategy, which
should be fixed in the driver itself.
4) In the team driver, this is the only place where the rcu
synchronization with unattached filter is used. Therefore, this
patch introduces synchronize_rcu() which is called from the
genetlink path to make sure the filter doesn't go away while packets
are still walking over it. I think we can revisit this once struct
bpf_prog (that only wraps specific bpf code bits) is in place, then
add some specific struct rcu_head in the scope of the team driver if
Jiri thinks this is needed.
Deferred rcu release for unattached filters was originally introduced
in 302d663 ("filter: Allow to create sk-unattached filters").

is now an independent structure maintained by mlx5_core.
mlx5_ib_dev now has a pointer to that struct.
This requires changing a lot of places where the core_dev
struct was accessed via mlx5_ib_dev (now, this needs to
be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
it is now mlx5_core which does pci_register_device (and not
mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
driver. This is very similar to the mechanism employed for
the mlx4 (ConnectX) driver. Once the HCA is initialized
(by mlx5_core), it invokes the interface drivers to do
their initializations.
4. There is a new event handler which the core registers:
mlx5_core_event(). This event handler invokes the
event handlers registered by the interfaces.
