commit 977dfef40c8996b69afe23a9094d184049efb7bb upstream.
The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a
new blacklist for the devices that are known to have empty codecs, and
one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f).
However, it turned out that the very same PCI SSID is used for the
previous model that does have the valid HD-audio codecs and the change
broke the sound on it.
Since the empty codec problem appear on the certain AMD platform (PCI
ID 1022:1487), this patch changes the blacklist matching to both PCI
ID and SSID using pci_match_id(). Also, the entry that was removed by
the previous fix for ASUS ROG Zenigh II is re-added.

commit 12dfd78e3a74825e6f0bc8df7ef9f938fbc6bfe3 upstream.
When starting shutdown in sctp_sf_do_dupcook_a(), get the value for
SHUTDOWN Cumulative TSN Ack from the new association, which is
reconstructed from the cookie, instead of the old association, which
the peer doesn't have anymore.
Otherwise the SHUTDOWN is either ignored or replied to with an ABORT
by the peer because CTSN Ack doesn't match the peer's Initial TSN.

commit 260916dfb48c374f7840f3b86e69afd3afdb6e96 upstream.
When we postpone a broadcast packet we save the source port in
the skb if it is local. However, the source port can disappear
before we get a chance to process the packet.
This patch fixes this by holding a ref count on the netdev.
It also delays the skb->cb modification until after we allocate
the new skb as you should not modify shared skbs.

commit c823abac17926767fb50175e098f087a6ac684c3 upstream.
When we unload the ep93xx_eth, whether we have opened the network
interface or not, we will either hit a kernel paging request error, or a
simple NULL pointer de-reference because:
- if ep93xx_open has been called, we have created a valid DMA mapping
for ep->descs, when we call ep93xx_stop, we also call
ep93xx_free_buffers, ep->descs now has a stale value
- if ep93xx_open has not been called, we have a NULL pointer for
ep->descs, so performing any operation against that address just won't
work
Fix this by adding a NULL pointer check for ep->descs which means that
ep93xx_free_buffers() was able to successfully tear down the descriptors
and free the DMA cookie as well.

commit 636c2628086e40c86dac7ddc84a1c4b4fcccc6e3 upstream.
In 93515d53b1
"net: move vlan pop/push functions into common code"
skb_vlan_pop was moved from its private location in openvswitch to
skbuff common code.
In case skb has non hw-accel vlan tag, the original 'pop_vlan()' assured
that skb->len is sufficient (if skb->len < VLAN_ETH_HLEN then pop was
considered a no-op).
This validation was moved as is into the new common 'skb_vlan_pop'.
Alas, in its original location (openvswitch), there was a guarantee that
'data' points to the mac_header, therefore the 'skb->len < VLAN_ETH_HLEN'
condition made sense.
However there's no such guarantee in the generic 'skb_vlan_pop'.
For short packets received in rx path going through 'skb_vlan_pop',
this causes 'skb_vlan_pop' to fail pop-ing a valid vlan hdr (in the non
hw-accel case) or to fail moving next tag into hw-accel tag.
Remove the 'skb->len < VLAN_ETH_HLEN' condition entirely:
It is superfluous since inner '__skb_vlan_pop' already verifies there
are VLAN_ETH_HLEN writable bytes at the mac_header.
Note this presents a slight change to skb_vlan_pop() users:
In case total length is smaller than VLAN_ETH_HLEN, skb_vlan_pop() now
returns an error, as opposed to previous "no-op" behavior.
Existing callers (e.g. tc act vlan, ovs) usually drop the packet if
'skb_vlan_pop' fails.

commit 7bb90c3715a496c650b2e879225030f9dd9cfafb upstream.
Adding fdb entries pointing to the bridge device uses fdb_insert(),
which lacks various checks and does not respect added_by_user flag.
As a result, some inconsistent behavior can happen:
* Adding temporary entries succeeds but results in permanent entries.
* Same goes for "dynamic" and "use".
* Changing mac address of the bridge device causes deletion of
user-added entries.
* Replacing existing entries looks successful from userspace but actually
not, regardless of NLM_F_EXCL flag.
Use the same logic as other entries and fix them.

commit b22ef2a0979f2b91cfeeabb086e4d665183a93a1 upstream.
The pincontrol registers of Tegra chips has multiple filed per
registers. There is two type of registers mux and drive. All
configurations belongs to one of these registers.
If any configurations are supported then <config>_bit is set to
bit position of these registers otherwise -1 to not support it.
The member is defined as
s32 <config>_bit:6;
So if config is not supported ifor given SoC then it is set to -1
in soc pinmmux table.
In common driver code, to find out that given config is supported
or not, it is checked as:
s8 bit = <config>_bit;
if (bit > 31) {
/* Not supported config */
}
But in this case, bit is s8 and hence for non supporting it is -1.
Correct the check as:
if (bit < 0) {
/* Not supported config */
}

commit 3b1dbfa14f97188ec33fdfc7acb66bea59a3bb21 upstream.
The current code will set _PAGE_USER to the access flags for any
fault address, because the ~ operation will be true for all address we
take a fault on. But setting _PAGE_USER also means that the fault will
be handled only if the page table have _PAGE_USER set. Hence there is
no security hole with the current code.
Now if it is an user space access, then the change in this patch really
don't have an impact because we have (!ctx->kernel) set true
and we take the if condition true.
Now kernel context created fault on an address in the kernel range
will result in a fault loop because we will not insert the
hash pte due to access and pte permission mismatch. This patch fix
the above issue.

commit be1faa92e83b1252d9200c59d8c98aab44463f1e upstream.
Currently the port based VLAN maps should be configured to allow every
port to egress frames on all other ports, except themselves.
The debugfs interface shows that they are misconfigured. For instance, a
7-port switch has the following content in the related register 0x06:
GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
...
6: 1fa4 1f0f 4 7f 7e 7d 7c 7b 7a 79
...
This means that port 3 is allowed to talk to port 2-6, but cannot talk
to ports 0 and 1. With this fix, port 3 can correctly talk to all ports
except 3 itself:
GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
...
6: 1fa4 1f0f 4 7e 7d 7b 77 6f 5f 3f

commit 996ecb8246676100af2a4dc1cfed747712a3c85f upstream.
In multi-chip systems, DSA Tag ports must learn SA addresses in order to
correctly switch frames between interconnected chips.
This fixes cross-chip hardware bridging in a VLAN filtering aware
system, because a bridge group gets implemented as an hardware 802.1Q
VLAN and thus DSA and user ports share the same FDB.

pskb_may_pull may fail due to various reasons (e.g. alloc failure), but the
skb isn't changed/dropped and processing continues so we shouldn't
increment tx_dropped.

commit 97db8afa2ab919fc400fe982f5054060868bdf07 upstream.
The mvneta driver advertises it supports IFF_UNICAST_FLT. However, it
actually does not. The hardware probably does support it, but there is
no code to configure the filter. As a quick and simple fix, remove the
flag. This will cause the core to fall back to promiscuous mode.

The function geneve_dev_create_fb() (only used by ovs) never calls
rtnl_configure_link(). The consequence is that dev->rtnl_link_state is

a RTM_DELLINK only if dev->rtnl_link_state is set to RTNL_LINK_INITIALIZED.

This is no issue so far, as only the rtnl core registers a netlink

one if new code makes use of the calcit hook.
