ibmvnic: Fix bugs and memory leaks
This is a small patch series fixing up some bugs and memory leaks
in the ibmvnic driver. The first fix frees up previously allocated
memory that should be freed in case of an error. The second fixes
a reset case that was failing due to TX/RX queue IRQ's being
erroneously disabled without being enabled again. The final patch
fixes incorrect reallocated of statistics buffers during a device
reset, resulting in loss of statistics information and a memory leak.

net: dsa: bcm_sf2: CFP fixes
This patch series fixes a number of usability issues with the SF2 Compact Field
Processor code:
- we would not be properly bound checking the location when we let the kernel
automatically place rules with RX_CLS_LOC_ANY
- when using IPv6 rules and user space specifies a location identifier we
would be off by one in what the chain ID (within the Broadcom tag) indicates
- it would be possible to delete one of the two slices of an IPv6 while leaving
the other one programming leading to various problems
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
It was possible to delete only one half of an IPv6, which would leave
the second half still programmed and possibly in use. Instead of
checking for the unused bitmap, we need to check the unique bitmap, and
refuse any deletion that does not match that criteria. We also need to
move that check from bcm_sf2_cfp_rule_del_one() into its caller:
bcm_sf2_cfp_rule_del() otherwise we would not be able to delete second
halves anymore that would not pass the first test.

We had several issues that would make the programming of IPv6 rules both
inconsistent and error prone:
- the chain ID that we would be asking the hardware to put in the
packet's Broadcom tag would be off by one, it would return one of the
two indexes, but not the one user-space specified
- when an user specified a particular location to insert a CFP rule at,
we would not be returning the same index, which would be confusing if
nothing else
- finally, like IPv4, it would be possible to overflow the last entry by
re-programming it
Fix this by swapping the usage of rule_index[0] and rule_index[1] where
relevant in order to return a consistent and correct user-space
experience.

When we let the kernel pick up a rule location with RX_CLS_LOC_ANY, we
would be able to overwrite the last rules because of a number of issues.
The IPv4 code path would not be checking that rule_index is within
bounds, and it would also only be allowed to pick up rules from range
0..126 instead of the full 0..127 range. This would lead us to allow
overwriting the last rule when we let the kernel pick-up the location.

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be
used as reference clock for the MAC unit. The clock signal must meet the
RGMII requirements to ensure the correct data transmission between the
MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle
requirement if the phy is configured as slave. For a complete
describtion look at the errata sheets: DS80000691D or DS80000692D.
The errata sheet recommends to force the phy into master mode whenever
there is a 1000Base-T link-up as work around. Only set the
"micrel,force-master" property if you use the phy reference clock provided
by CLK125_NDO pin as MAC reference clock in your application.
Attenation, this workaround is only usable if the link partner can
be configured to slave mode for 1000Base-T.

Packet sockets allow construction of packets shorter than
dev->hard_header_len to accommodate protocols with variable length
link layer headers. These packets are padded to dev->hard_header_len,
because some device drivers interpret that as a minimum packet size.
packet_snd reserves dev->hard_header_len bytes on allocation.
SOCK_DGRAM sockets call skb_push in dev_hard_header() to ensure that
link layer headers are stored in the reserved range. SOCK_RAW sockets
do the same in tpacket_snd, but not in packet_snd.
Syzbot was able to send a zero byte packet to a device with massive
116B link layer header, causing padding to cross over into skb_shinfo.
Fix this by writing from the start of the llheader reserved range also
in the case of packet_snd/SOCK_RAW.
Update skb_set_network_header to the new offset. This also corrects
it for SOCK_DGRAM, where it incorrectly double counted reserve due to
the skb_push in dev_hard_header.

And then just one minor build fix, and the removal of an unused variable that

Intel Wired LAN Driver Updates 2018-05-11
This series contains fixes to the ice, ixgbe and ixgbevf drivers.
Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or
not the hardware responds with an error in the ice driver.
Emil adds a check for unsupported module during the reset routine for
ixgbe.
Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the
correct return value (int).
Colin Ian King fixes a potential resource leak in ixgbe, where we were
not freeing ipsec in our cleanup path.

David Howells says:
====================
rxrpc: Fixes
Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:
(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.
Fix this by returning 'netdev_tx_t' in this driver too.
