      USB: core: fix check for duplicate endpoints · ecaaef6b
      Johan Hovold authored 
      commit 3e4f8e21 upstream.

Amend the endpoint-descriptor sanity checks to detect all duplicate
endpoint addresses in a configuration.

Commit 0a8fd134 ("USB: fix problems with duplicate endpoint
addresses") added a check for duplicate endpoint addresses within a
single alternate setting, but did not look for duplicate addresses in
other interfaces.

The current check would also not detect all duplicate addresses when one
endpoint is as a (bi-directional) control endpoint.

This specifically avoids overwriting the endpoint entries in struct
usb_device when enabling a duplicate endpoint, something which could
potentially lead to crashes or leaks, for example, when endpoints are
later disabled.

      vlan: fix memory leak in vlan_dev_set_egress_priority · a57180da
      Eric Dumazet authored 
      [ Upstream commit 9bbd917e ]

There are few cases where the ndo_uninit() handler might be not
called if an error happens while device is initialized.

Since vlan_newlink() calls vlan_changelink() before
trying to register the netdevice, we need to make sure
vlan_dev_uninit() has been called at least once,
or we might leak allocated memory.

      net: sch_prio: When ungrafting, replace with FIFO · f863b71a
      Petr Machata authored 
      [ Upstream commit 240ce7f6 ]

When a child Qdisc is removed from one of the PRIO Qdisc's bands, it is
replaced unconditionally by a NOOP qdisc. As a result, any traffic hitting
that band gets dropped. That is incorrect--no Qdisc was explicitly added
when PRIO was created, and after removal, none should have to be added
either.

Fix PRIO by first attempting to create a default Qdisc and only falling
back to noop when that fails. This pattern of attempting to create an
invisible FIFO, using NOOP only as a fallback, is also seen in other
Qdiscs.

      vxlan: fix tos value before xmit · 57574c58
      Hangbin Liu authored 
      [ Upstream commit 71130f29 ]

Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter
tos value by RT_TOS() instead of using config tos directly.

vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't
return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS()
directly in function ip_tunnel_ecn_encap().

      tcp: fix "old stuff" D-SACK causing SACK to be treated as D-SACK · ea3cc787
      Pengcheng Yang authored 
      [ Upstream commit c9655008 ]

When we receive a D-SACK, where the sequence number satisfies:
	undo_marker <= start_seq < end_seq <= prior_snd_una
we consider this is a valid D-SACK and tcp_is_sackblock_valid()
returns true, then this D-SACK is discarded as "old stuff",
but the variable first_sack_index is not marked as negative
in tcp_sacktag_write_queue().

If this D-SACK also carries a SACK that needs to be processed
(for example, the previous SACK segment was lost), this SACK
will be treated as a D-SACK in the following processing of
tcp_sacktag_write_queue(), which will eventually lead to
incorrect updates of undo_retrans and reordering.

      sctp: free cmd->obj.chunk for the unprocessed SCTP_CMD_REPLY · 86c2a390
      Xin Long authored 
      [ Upstream commit be7a7729 ]

This patch is to fix a memleak caused by no place to free cmd->obj.chunk
for the unprocessed SCTP_CMD_REPLY. This issue occurs when failing to
process a cmd while there're still SCTP_CMD_REPLY cmds on the cmd seq
with an allocated chunk in cmd->obj.chunk.

So fix it by freeing cmd->obj.chunk for each SCTP_CMD_REPLY cmd left on
the cmd seq when any cmd returns error. While at it, also remove 'nomem'
label.

      pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM · 9e9dcbc9
      Eric Dumazet authored 
      [ Upstream commit d9e15a27 ]

As diagnosed by Florian :

If TCA_FQ_QUANTUM is set to 0x80000000, fq_deueue()
can loop forever in :

if (f->credit <= 0) {
  f->credit += q->quantum;
  goto begin;
}

... because f->credit is either 0 or -2147483648.

Let's limit TCA_FQ_QUANTUM to no more than 1 << 20 :
This max value should limit risks of breaking user setups
while fixing this bug.

      macvlan: do not assume mac_header is set in macvlan_broadcast() · 9b266c6c
      Eric Dumazet authored 
      [ Upstream commit 96cc4b69 ]

Use of eth_hdr() in tx path is error prone.

Many drivers call skb_reset_mac_header() before using it,
but others do not.

Commit 6d1ccff6 ("net: reset mac header in dev_start_xmit()")
attempted to fix this generically, but commit d346a3fa
("packet: introduce PACKET_QDISC_BYPASS socket option") brought
back the macvlan bug.

Lets add a new helper, so that tx paths no longer have
to call skb_reset_mac_header() only to get a pointer
to skb->data.

Hopefully we will be able to revert 6d1ccff6
("net: reset mac header in dev_start_xmit()") and save few cycles
in transmit fast path.

      llc2: Fix return statement of llc_stat_ev_rx_null_dsap_xid_c (and _test_c) · 04631ca0
      Chan Shu Tak, Alex authored 
      [ Upstream commit af1c0e4e ]

When a frame with NULL DSAP is received, llc_station_rcv is called.
In turn, llc_stat_ev_rx_null_dsap_xid_c is called to check if it is a NULL
XID frame. The return statement of llc_stat_ev_rx_null_dsap_xid_c returns 1
when the incoming frame is not a NULL XID frame and 0 otherwise. Hence, a
NULL XID response is returned unexpectedly, e.g. when the incoming frame is
a NULL TEST command.

To fix the error, simply remove the conditional operator.

A similar error in llc_stat_ev_rx_null_dsap_test_c is also fixed.
