====================
Netfilter/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:

1) Fix SIP conntrack with phones sending session descriptions for different
   media types but same port numbers, from Florian Westphal.

2) Fix incorrect rtnl_lock mutex logic from IPVS sync thread, from Julian
   Anastasov.

3) Skip compat array allocation in ebtables if there is no entries, also
   from Florian.

4) Do not lose left/right bits when shifting marks from xt_connmark, from
   Jack Ma.

5) Silence false positive memleak in conntrack extensions, from Cong Wang.

6) Fix CONFIG_NF_REJECT_IPV6=m link problems, from Arnd Bergmann.

7) Cannot kfree rule that is already in list in nf_tables, switch order
   so this error handling is not required, from Florian Westphal.

8) Release set name in error path, from Florian.

9) include kmemleak.h in nf_conntrack_extend.c, from Stepheh Rothwell.

10) NAT chain and extensions depend on NF_TABLES.

11) Out of bound access when renaming chains, from Taehee Yoo.

12) Incorrect casting in xt_connmark leads to wrong bitshifting.

      ipv6: add RTA_TABLE and RTA_PREFSRC to rtm_ipv6_policy · aa8f8778
      Eric Dumazet authored 
      KMSAN reported use of uninit-value that I tracked to lack
of proper size check on RTA_TABLE attribute.

I also believe RTA_PREFSRC lacks a similar check.

      bonding: do not set slave_dev npinfo before slave_enable_netpoll in bond_enslave · ddea788c
      Xin Long authored 
      After Commit 8a8efa22 ("bonding: sync netpoll code with bridge"), it
would set slave_dev npinfo in slave_enable_netpoll when enslaving a dev
if bond->dev->npinfo was set.

However now slave_dev npinfo is set with bond->dev->npinfo before calling
slave_enable_netpoll. With slave_dev npinfo set, __netpoll_setup called
in slave_enable_netpoll will not call slave dev's .ndo_netpoll_setup().
It causes that the lower dev of this slave dev can't set its npinfo.

One way to reproduce it:

  # modprobe bonding
  # brctl addbr br0
  # brctl addif br0 eth1
  # ifconfig bond0 192.168.122.1/24 up
  # ifenslave bond0 eth2
  # systemctl restart netconsole
  # ifenslave bond0 br0
  # ifconfig eth2 down
  # systemctl restart netconsole

The netpoll won't really work.

This patch is to remove that slave_dev npinfo setting in bond_enslave().

      tcp: don't read out-of-bounds opsize · 7e5a206a
      Jann Horn authored 
      The old code reads the "opsize" variable from out-of-bounds memory (first
byte behind the segment) if a broken TCP segment ends directly after an
opcode that is neither EOL nor NOP.

The result of the read isn't used for anything, so the worst thing that
could theoretically happen is a pagefault; and since the physmap is usually
mostly contiguous, even that seems pretty unlikely.

The following C reproducer triggers the uninitialized read - however, you
can't actually see anything happen unless you put something like a
pr_warn() in tcp_parse_md5sig_option() to print the opsize.

====================
pull-request: bpf 2018-04-21

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a deadlock between mm->mmap_sem and bpf_event_mutex when
   one task is detaching a BPF prog via perf_event_detach_bpf_prog()
   and another one dumping through bpf_prog_array_copy_info(). For
   the latter we move the copy_to_user() out of the bpf_event_mutex
   lock to fix it, from Yonghong.

2) Fix test_sock and test_sock_addr.sh failures. The former was
   hitting rlimit issues and the latter required ping to specify
   the address family, from Yonghong.

3) Remove a dead check in sockmap's sock_map_alloc(), from Jann.

4) Add generated files to BPF kselftests gitignore that were previously
   missed, from Anders.

net: sched: ife: malformed ife packet fixes

As promised at netdev 2.2 tc workshop I am working on adding scapy support for
tdc testing. It is still work in progress. I will submit the patches to tdc
later (they are not in good shape yet). The good news is I have been able to
find bugs which normal packet testing would not be able to find.
With fuzzy testing I was able to craft certain malformed packets that IFE
action was not able to deal with. This patch set fixes those bugs.

changes since v4:
 - use pskb_may_pull before pointer assign

changes since v3:
 - use pskb_may_pull

changes since v2:
 - remove inline from __ife_tlv_meta_valid
 - add const to cast to meta_tlvhdr
 - add acked and reviewed tags

      strparser: Do not call mod_delayed_work with a timeout of LONG_MAX · 7c5aba21
      Doron Roberts-Kedes authored 
      struct sock's sk_rcvtimeo is initialized to
LONG_MAX/MAX_SCHEDULE_TIMEOUT in sock_init_data. Calling
mod_delayed_work with a timeout of LONG_MAX causes spurious execution of
the work function. timer->expires is set equal to jiffies + LONG_MAX.
When timer_base->clk falls behind the current value of jiffies,
the delta between timer_base->clk and jiffies + LONG_MAX causes the
expiration to be in the past. Returning early from strp_start_timer if
timeo == LONG_MAX solves this problem.

Found while testing net/tls_sw recv path.

      ipv6: sr: fix NULL pointer dereference in seg6_do_srh_encap()- v4 pkts · a957fa19
      Ahmed Abdelsalam authored 
      In case of seg6 in encap mode, seg6_do_srh_encap() calls set_tun_src()
in order to set the src addr of outer IPv6 header.

The net_device is required for set_tun_src(). However calling ip6_dst_idev()
on dst_entry in case of IPv4 traffic results on the following bug.

Using just dst->dev should fix this BUG.

  i915:
   - an oops fix
   - two race fixes
   - some gvt fixes

  amdgpu:
   - dark screen fix
   - clk/voltage fix
   - vega12 smu fix

  vc4:
   - memory leak fix

  exynos just drops some code"

Remove Exynos specific framebuffer structure and
relevant functions.
- it removes exynos_drm_fb structure which is a wrapper of
  drm_framebuffer and unnecessary two exynos specific callback
  functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
  because we can reuse existing drm common callback ones instead.
