1GbE Intel Wired LAN Driver Updates 2016-09-27

This series contains updates to igb and igbvf.

Wei Yongjun makes a function static to shut up sparse.

Todd bumps the igb and igbvf version, which is long overdue.

Jake fixes an issue where the PPS SYS_WRAP interrupt was not re-enabled
after a reset, which resulted in disabling of the PPS signaling.

v2: dropped patch 5 of the original series, since the PCI quirk patch
    needs to be reworked by Alex and Sasha to address issues that Bjorn
    Helgaas and Alex Williamson brought up.

net: bcmgenet: only use new api ethtool_{get|set}_link_ksettings

Some times ago, a serie of patches were committed :
- commit 62469c76 ("net: ethernet: bcmgenet: use phydev from struct net_device")
- commit 6b352ebc ("net: ethernet: broadcom: bcmgenet: use new api ethtool_{get|set}_link_ksettings")
The first patch add a regression on this driver, so it should be reverted.
As the second patch depend on the former, it should be reverted too.

The first patch is buggy because there is a "trick" in this driver.
The structure phydev is kept in the private data when the interface
go down, and used when the interface go up to enable the phy before
the function phy_connect is called.

I don't have this hardware, neither the datasheet. So I won't
update the driver to avoid this trick.

But the real goal of the first serie was to move to the new api
ethtool_{get|set}_link_ksettings. So I provide a new version of
the patch without the "cleaning" of driver to use the phydev
store in the net_device structure.

Changelog:
v3:
- use priv instead of dev (so all the code use the same phydev)
v2:
- use Florian Fainelli patches for the revert instead of Jaedon Shin
- simply use net: bcmgenet: for the prefix of the patch

This reverts commit 62469c76 ("net: ethernet: bcmgenet: use phydev

expose the following behavior after an ifconfig down/up sequence:

This was previously fixed by commit 5dbebbb4 ("net: bcmgenet:
Software reset EPHY after power on") but the commit we are reverting was
essentially making this previous commit void, here is why.

Without commit 62469c76 we would have the following scenario after
an ifconfig down then up sequence:

- bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is
  initialized *before* we get to initialize the UniMAC, this is
  critical to ensure the PHY is in a correct state, priv->phydev is
  valid, this code executes fine

- second time from bcmgenet_mii_probe(), through the normal
  phy_init_hw() call (which arguably could be optimized out)

Everything is fine in that case. With commit 62469c76, we would have
the following scenario to happen after an ifconfig down then up
sequence:

- bcmgenet_close() calls phy_disonnect() which makes dev->phydev become
  NULL

- when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from
  bcmgenet_power_up() to initialize the internal PHY, the NULL check
  becomes true, so we do not reset the PHY, yet we keep going on and
  initialize the UniMAC, causing MAC activity to occur

- we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is
  too late, the PHY is botched, and causes the above bogus pings/packets
  transmission/reception to occur

This prevent future potential pointer leaks when an unprivileged eBPF
program will read a pointer value from its context. Even if
is_valid_access() returns a pointer type, the eBPF verifier replace it
with UNKNOWN_VALUE. The register value that contains a kernel address is
then allowed to leak. Moreover, this fix allows unprivileged eBPF
programs to use functions with (legitimate) pointer arguments.

Not an issue currently since reg_type is only set for PTR_TO_PACKET or
PTR_TO_PACKET_END in XDP and TC programs that can only be loaded as
privileged. For now, the only unprivileged eBPF program allowed is for
socket filtering and all the types from its context are UNKNOWN_VALUE.
However, this fix is important for future unprivileged eBPF programs
which could use pointers in their context.

I stumbled over a new warning during randconfig testing,
with CONFIG_BPF_SYSCALL disabled:

drivers/net/ethernet/netronome/nfp/nfp_net_offload.c: In function 'nfp_net_bpf_offload':
drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: '*((void *)&res+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: 'res.n_instr' may be used uninitialized in this function [-Werror=maybe-uninitialized]

As far as I can tell, this is a false positive caused by the compiler
getting confused about a function that is partially inlined, but it's
easy to avoid while improving the code:

The nfp_bpf_jit() stub helper for that configuration is unusual as it
is defined in a header file but not marked 'static inline'. By moving
the compile-time check into the caller using the IS_ENABLED() macro,
we can remove that stub and simplify the nfp_net_bpf_offload_prepare()
function enough to unconfuse the compiler.

   specified by RFC3261, from Marco Angaroni.

3) Remove useless code in FTP conntrack helper, also from Gao Feng.

4) Add number generation expression for nf_tables, with random and
   incremental generators. This also includes specific offset to add
   to the result, patches from Laura Garcia Liebana. Liping Zhang
   follows with a fix to avoid a race in this new expression.

5) Fix new quota expression inversion logic, added in the previous
   pull request.

6) Missing validation of queue configuration in nft_queue, patch
   from Liping Zhang.

7) Remove unused ctl_table_path, as part of the deprecation of the
   ip_conntrack sysctl interface coming in the previous batch.
   Again from Liping Zhang.

8) Add offset attribute to nft_hash expression, so we can generate
   any output from a specific base offset. Moreover, check for
   possible overflow, patches from Laura Garcia.

9) Allow to invert dynamic set insertion from packet path, to check
   for overflows in case the set is full.

10) Revisit nft_set_pktinfo*() logic from nf_tables to ensure
    proper initialization of layer 4 protocol. Consolidate pktinfo
    structure initialization for bridge and netdev families.

11) Do not inconditionally drop IPv6 packets that we cannot parse
    transport protocol for ip6 and inet families, let the user decide
    on this via ruleset policy.

12) Get rid of gotos in __nf_ct_try_assign_helper().

13) Check for return value in register_netdevice_notifier() and
    nft_register_chain_type(), patches from Gao Feng.

14) Get rid of CONFIG_IP6_NF_IPTABLES dependency in nf_queue
    infrastructure that is common to nf_tables, from Liping Zhang.

15) Disable 'found' and 'searched' stats that are updates from the
    packet hotpath, not very useful these days.

16) Validate maximum value of u32 netlink attributes in nf_tables,
    this introduces nft_parse_u32_check(). From Laura Garcia.

17) Add missing code to integrate nft_queue with maps, patch from
    Liping Zhang. This also includes missing support ranges in
    nft_queue bridge family.

18) Fix check in nft_payload_fast_eval() that ensure that we don't
    go over the skbuff data boundary, from Liping Zhang.

19) Check if transport protocol is set from nf_tables tracing and
    payload expression. Again from Liping Zhang.

20) Use net_get_random_once() whenever possible, from Gao Feng.

21) Replace hardcoded value by sizeof() in xt_helper, from Gao Feng.

22) Remove superfluous check for found element in nft_lookup.

23) Simplify TCPMSS logic to check for minimum MTU, from Gao Feng.

24) Replace double linked list by single linked list in Netfilter
    core hook infrastructure, patchset from Aaron Conole. This
    includes several patches to prepare this update.

25) Fix wrong sequence adjustment of TCP RST with no ACK, from
    Gao Feng.

26) Relax check for direction attribute in nft_ct for layer 3 and 4
    protocol fields, from Liping Zhang.

27) Add new revision for hashlimit to support higher pps of upto 1
    million, from Vishwanath Pai.

28) Evict stale entries in nf_conntrack when reading entries from
    /proc/net/nf_conntrack, from Florian Westphal.

29) Fix transparent match for IPv6 request sockets, from Krisztian
    Kovacs.

30) Add new range expression for nf_tables.

31) Add missing code to support for flags in nft_log. Expose NF_LOG_*
    flags via uapi and use it from the generic logging infrastructure,
    instead of using xt specific definitions, from Liping Zhang.

nf_log is used by both nftables and iptables, so use XT_LOG_XXX macros
here is not appropriate. Replace them with NF_LOG_XXX.

NFTA_LOG_FLAGS attribute is already supported, but the related
NF_LOG_XXX flags are not exposed to the userspace. So we cannot
explicitly enable log flags to log uid, tcp sequence, ip options
and so on, i.e. such rule "nft add rule filter output log uid"
is not supported yet.

So move NF_LOG_XXX macro definitions to the uapi/../nf_log.h. In
order to keep consistent with other modules, change NF_LOG_MASK to
refer to all supported log flags. On the other hand, add a new
NF_LOG_DEFAULT_MASK to refer to the original default log flags.

Finally, if user specify the unsupported log flags or NFTA_LOG_GROUP
and NFTA_LOG_FLAGS are set at the same time, report EINVAL to the
userspace.
