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
workFix 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.Fixes: 1d22e05df818 ("[PATCH] Cirrus Logic ep93xx ethernet driver")

Only the 578xx adapters are capable of configuring UDP ports for
the purpose of tunnelling - doing the same on 577xx might lead to
a firmware assertion.
We're already not claiming support for any related feature for such
devices, but we also need to prevent the configuration of the UDP
ports to the device in this case.Fixes: f34fa14cc033 ("bnx2x: Add vxlan RSS support")

Until interface is up [and assuming ringparams weren't explicitly
configured] when queried for the size of its rings bnx2x would
claim they're the maximal size by default.
That is incorrect as by default the maximal number of buffers would
be equally divided between the various rx rings.This prevents the user from actually setting the number of elements
on each rx ring to be of maximal size prior to transitioning the
interface into up state.To fix this, make a rough estimation about the number of buffers.
It wouldn't always be accurate, but it would be much better than
current estimation and would allow users to increase number of
buffers during early initialization of the interface.Reported-by: Seymour, Shane

Macro BNX2X_ALLOC_AND_SET(arr, lbl, func) calls kmalloc() to allocate
memory, and jumps to label "lbl" if the allocation fails. Label "lbl"
first cleans memory and then returns variable rc. Before calling the
macro, the value of variable rc is 0. Because 0 means no error, the
callers of bnx2x_init_firmware() may be misled. This patch fixes the bug,

Prior to commit c0371da6047a ("put iov_iter into msghdr") in v3.19, there
was no check that the iovec contained enough bytes for an ICMP header,
and the read loop would walk across neighboring stack contents. Since the
iov_iter conversion, bad arguments are noticed, but the returned error is
EFAULT. Returning EINVAL is a clearer error and also solves the problem
prior to v3.19.This was found using trinity with KASAN on v3.18:

====================
IPv4 FIB suffix length fixesIn reviewing the patch from Robert Shearman and looking over the code I
realized there were a few different bugs we were still carrying in the IPv4
FIB lookup code.These two patches are based off of Robert's original patch, but take things
one step further by splitting them up to address two additional issues I
found.So first have Robert's original patch which was addressing the fact that
us calling update_suffix in resize is expensive when it is called per add.
To address that I incorporated the core bit of the patch which was us
dropping the update_suffix call from resize.The first patch in the series does a rename and fix on the push_suffix and
pull_suffix code. Specifically we drop the need to pass a leaf and
secondly we fix things so we pull the suffix as long as the value of the
suffix in the node is dropping.The second patch addresses the original issue reported as well as
optimizing the code for the fact that update_suffix is only really meant to
go through and clean things up when we are decreasing a suffix. I had
originally added code for it to somehow cause an increase, but if we push
the suffix when a new leaf is added we only ever have to handle pulling
down the suffix with update_suffix so I updated the code to reflect that.As far as side effects the only ones I think that will be obvious should be
the fact that some routes may be able to be found earlier since before we
relied on resize to update the suffix lengths, and now we are updating them
before we add or remove the leaf.
====================Signed-off-by: David S. Miller
-
It has been reported that update_suffix can be expensive when it is called
on a large node in which most of the suffix lengths are the same. The time
required to add 200K entries had increased from around 3 seconds to almost
49 seconds.In order to address this we need to move the code for updating the suffix
out of resize and instead just have it handled in the cases where we are
pushing a node that increases the suffix length, or will decrease the
suffix length.Fixes: 5405afd1a306 ("fib_trie: Add tracking value for suffix length")

It wasn't necessary to pass a leaf in when doing the suffix updates so just
drop it. Instead just pass the suffix and work with that.Since we dropped the leaf there is no need to include that in the name so
the names are updated to node_push_suffix and node_pull_suffix.Finally I noticed that the logic for pulling the suffix length back
actually had some issues. Specifically it would stop prematurely if there
was a longer suffix, but it was not as long as the original suffix. I
updated the code to address that in node_pull_suffix.Fixes: 5405afd1a306 ("fib_trie: Add tracking value for suffix length")

Qian Zhang (张谦) reported a potential socket buffer overflow in
tipc_msg_build() which is also known as CVE-2016-8632: due to
insufficient checks, a buffer overflow can occur if MTU is too short for
even tipc headers. As anyone can set device MTU in a user/net namespace,
this issue can be abused by a regular user.As agreed in the discussion on Ben Hutchings' original patch, we should
check the MTU at the moment a bearer is attached rather than for each
processed packet. We also need to repeat the check when bearer MTU is
adjusted to new device MTU. UDP case also needs a check to avoid
overflow when calculating bearer MTU.Fixes: b97bf3fd8f6a ("[TIPC] Initial merge")

Commit bfe9b9d2df66 ("cdc_ether: Improve ZTE MF823/831/910 handling")
introduced a work-around in usbnet_cdc_status() for devices that exported
cdc carrier on twice on connect. Before the commit, this behavior caused
the link state to be incorrect. It was assumed that all CDC Ethernet
devices would either export this behavior, or send one off and then one on
notification (which seems to be the default behavior).Unfortunately, it turns out multiple devices sends a connection
notification multiple times per second (via an interrupt), even when
connection state does not change. This has been observed with several
different USB LAN dongles (at least), for example 13b1:0041 (Linksys).
After bfe9b9d2df66, the link state has been set as down and then up for
each notification. This has caused a flood of Netlink NEWLINK messages and
syslog to be flooded with messages similar to:cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped
This commit fixes the behavior by reverting usbnet_cdc_status() to how it
was before bfe9b9d2df66. The work-around has been moved to a separate
status-function which is only called when a known, affect device is
detected.v1->v2:
* Do not open-code netif_carrier_ok() (thanks Henning Schild).
* Call netif_carrier_off() instead of usb_link_change(). This prevents
calling schedule_work() twice without giving the work queue a chance to be
processed (thanks Bjørn Mork).Fixes: bfe9b9d2df66 ("cdc_ether: Improve ZTE MF823/831/910 handling")

unregister_netdevice_notifier(), else we could trigger a panic

This reverts commit ae148b085876fa771d9ef2c05f85d4b4bf09ce0d
("ip6_tunnel: Update skb->protocol to ETH_P_IPV6 in ip6_tnl_xmit()").skb->protocol is now set in __ip_local_out() and __ip6_local_out() before
dst_output() is called. It is no longer necessary to do it for each tunnel.Cc: stable@vger.kernel.org

When xfrm is applied to TSO/GSO packets, it follows this path:
xfrm_output() -> xfrm_output_gso() -> skb_gso_segment()
where skb_gso_segment() relies on skb->protocol to function properly.
This patch sets skb->protocol to ETH_P_IPV6 before dst_output() is called,
fixing a bug where GSO packets sent through an ipip6 tunnel are dropped
when xfrm is involved.Cc: stable@vger.kernel.org
