      tcp: setup timestamp offset when write_seq already set · 00355fa5
      Alexey Kodanev authored 
      Found that when randomized tcp offsets are enabled (by default)
TCP client can still start new connections without them. Later,
if server does active close and re-uses sockets in TIME-WAIT
state, new SYN from client can be rejected on PAWS check inside
tcp_timewait_state_process(), because either tw_ts_recent or
rcv_tsval doesn't really have an offset set.

Here is how to reproduce it with LTP netstress tool:
    netstress -R 1 &
    netstress -H 127.0.0.1 -lr 1000000 -a1

      net/dccp: fix use after free in tw_timer_handler() · ec7cb62d
      Andrey Ryabinin authored 
      DCCP doesn't purge timewait sockets on network namespace shutdown.
So, after net namespace destroyed we could still have an active timer
which will trigger use after free in tw_timer_handler():

      uapi: fix linux/if.h userspace compilation errors · 2618be7d
      Dmitry V. Levin authored 
      Include <sys/socket.h> (guarded by ifndef __KERNEL__) to fix
the following linux/if.h userspace compilation errors:

/usr/include/linux/if.h:234:19: error: field 'ifru_addr' has incomplete type
   struct sockaddr ifru_addr;
/usr/include/linux/if.h:235:19: error: field 'ifru_dstaddr' has incomplete type
   struct sockaddr ifru_dstaddr;
/usr/include/linux/if.h:236:19: error: field 'ifru_broadaddr' has incomplete type
   struct sockaddr ifru_broadaddr;
/usr/include/linux/if.h:237:19: error: field 'ifru_netmask' has incomplete type
   struct sockaddr ifru_netmask;
/usr/include/linux/if.h:238:20: error: field 'ifru_hwaddr' has incomplete type
   struct  sockaddr ifru_hwaddr;

This also fixes userspace compilation of the following uapi headers:
  linux/atmbr2684.h
  linux/gsmmux.h
  linux/if_arp.h
  linux/if_bonding.h
  linux/if_frad.h
  linux/if_pppox.h
  linux/if_tunnel.h
  linux/netdevice.h
  linux/route.h
  linux/wireless.h

As no uapi header provides a definition of struct sockaddr, inclusion
of <sys/socket.h> seems to be the most conservative and the only safe
fix available.

All current users of <linux/if.h> are very likely to be including
<sys/socket.h> already because the latter is the sole provider
of struct sockaddr definition in libc, so adding a uapi header
with a definition of struct sockaddr would create a potential
conflict with <sys/socket.h>.

Replacing struct sockaddr in the definition of struct ifreq with
a different type would create a potential incompatibility with current
users of struct ifreq who might rely on ifru_addr et al members being
of type struct sockaddr.

      l2tp: Avoid schedule while atomic in exit_net · 12d656af
      Ridge Kennedy authored 
      While destroying a network namespace that contains a L2TP tunnel a
"BUG: scheduling while atomic" can be observed.

Enabling lockdep shows that this is happening because l2tp_exit_net()
is calling l2tp_tunnel_closeall() (via l2tp_tunnel_delete()) from
within an RCU critical section.

l2tp_exit_net() takes rcu_read_lock_bh()
  << list_for_each_entry_rcu() >>
  l2tp_tunnel_delete()
    l2tp_tunnel_closeall()
      __l2tp_session_unhash()

This bug can easily be reproduced with a few steps:

 $ sudo unshare -n bash  # Create a shell in a new namespace

 # ip addr add 127.0.0.1 dev lo
 # ip l2tp add tunnel remote 127.0.0.1 local 127.0.0.1 tunnel_id 1 \

 # ip l2tp add session name foo tunnel_id 1 session_id 1 \
    peer_session_id 1
 # ip link set foo up
 # exit  # Exit the shell, in turn exiting the namespace
 $ dmesg
 ...
 [942121.089216] BUG: scheduling while atomic: kworker/u16:3/13872/0x00000200
 ...

To fix this, move the call to l2tp_tunnel_closeall() out of the RCU
critical section, and instead call it from l2tp_tunnel_del_work(), which
is running from the l2tp_wq workqueue.

      net: emac: add support for device-tree based PHY discovery and setup · a577ca6b
      Christian Lamparter authored 
      This patch adds glue-code that allows the EMAC driver to interface
with the existing dt-supported PHYs in drivers/net/phy.

Because currently, the emac driver maintains a small library of
supported phys for in a private phy.c file located in the drivers
directory.

The support is limited to mostly single ethernet transceiver like the:
CIS8201, BCM5248, ET1011C, Marvell 88E1111 and 88E1112, AR8035.

However, routers like the Netgear WNDR4700 and Cisco Meraki MX60(W)
have a 5-port switch (AR8327N) attached to the EMAC. The switch chip
is supported by the qca8k mdio driver, which uses the generic phy
library. Another reason is that PHYLIB also supports the BCM54610,
which was used for the Western Digital My Book Live.

This will now also make EMAC select PHYLIB.

   - Add new AUX vectors describing the processor's cache geometry, to
     be used by glibc.

   - The ability for a guest to ask the hypervisor to resize the guest's
     hash table, and in addition support for doing so automatically when
     memory is hotplugged into/out-of the guest. This allows the hash
     table to be sized based on the current memory usage of the guest,
     rather than the maximum possible memory usage.

   - Implementation of optprobes (kprobe optimisation) for powerpc.

  In addition there's the topic branch shared with the KVM tree, which
  includes support for guests to use the Radix MMU on Power9.
