    l2tp: Fix PPP header erasure and memory leak

    [ Upstream commit 55b92b7a11690bc377b5d373872a6b650ae88e64 ]

    Copy user data after PPP framing header. This prevents erasure of the
    added PPP header and avoids leaking two bytes of uninitialised memory
    at the end of skb's data buffer.

    packet: packet_getname_spkt: make sure string is always 0-terminated

    [ Upstream commit 2dc85bf323515e59e15dfa858d1472bb25cad0fe ]

    uaddr->sa_data is exactly of size 14, which is hard-coded here and
    passed as a size argument to strncpy(). A device name can be of size
    IFNAMSIZ (== 16), meaning we might leave the destination string
    unterminated. Thus, use strlcpy() and also sizeof() while we're
    at it. We need to memset the data area beforehand, since strlcpy
    does not padd the remaining buffer with zeroes for user space, so
    that we do not possibly leak anything.

    I did not hit this with the lksctp-tools functional tests, but with a
    small, multi-threaded test program, that heavily allocates, binds,
    listens and waits in accept on sctp sockets, and then randomly kills
    some of them (no need for an actual client in this case to hit this).
    Then, again, allocating, binding, etc, and then killing child processes.

    This panic then only occurs when ``echo 1 > /proc/sys/net/sctp/auth_enable''
    is set. The cause for that is actually very simple: in sctp_endpoint_init()
    we enter the path of sctp_auth_init_hmacs(). There, we try to allocate
    our crypto transforms through crypto_alloc_hash(). In our scenario,
    it then can happen that crypto_alloc_hash() fails with -EINTR from
    crypto_larval_wait(), thus we bail out and release the socket via
    sk_common_release(), sctp_destroy_sock() and hit the NULL pointer
    dereference as soon as we try to access members in the endpoint during
    sctp_endpoint_free(), since endpoint at that time is still NULL. Now,
    if we have that case, we do not need to do any cleanup work and just
    leave the destruction handler.

    net: force a reload of first item in hlist_nulls_for_each_entry_rcu

    [ Upstream commit c87a124a5d5e8cf8e21c4363c3372bcaf53ea190 ]

    Roman Gushchin discovered that udp4_lib_lookup2() was not reloading
    first item in the rcu protected list, in case the loop was restarted.

    This produced soft lockups as in https://lkml.org/lkml/2013/4/16/37

    rcu_dereference(X)/ACCESS_ONCE(X) seem to not work as intended if X is
    ptr->field :

    In some cases, gcc caches the value or ptr->field in a register.

    Use a barrier() to disallow such caching, as documented in
    Documentation/atomic_ops.txt line 114

    Thanks a lot to Roman for providing analysis and numerous patches.

    net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg

    [ Upstream commits 1be374a0518a288147c6a7398792583200a67261 and
      a7526eb5d06b0084ef12d7b168d008fcf516caab ]

    MSG_CMSG_COMPAT is (AFAIK) not intended to be part of the API --
    it's a hack that steals a bit to indicate to other networking code
    that a compat entry was used.  So don't allow it from a non-compat
    syscall.

    This prevents an oops when running this code:

    int main()
    {
        int s;
        struct sockaddr_in addr;
        struct msghdr *hdr;

        char *highpage = mmap((void*)(TASK_SIZE_MAX - 4096), 4096,
                              PROT_READ | PROT_WRITE,
                              MAP_PRIVATE | MAP_ANONYMOUS | MAP_FIXED, -1, 0);
        if (highpage == MAP_FAILED)
            err(1, "mmap");

        s = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
        if (s == -1)
            err(1, "socket");

            addr.sin_family = AF_INET;
            addr.sin_port = htons(1);
            addr.sin_addr.s_addr = htonl(INADDR_LOOPBACK);
        if (connect(s, (struct sockaddr*)&addr, sizeof(addr)) != 0)
            err(1, "connect");

        void *evil = highpage + 4096 - COMPAT_MSGHDR_SIZE;
        printf("Evil address is %p\n", evil);

        if (syscall(__NR_sendmmsg, s, evil, 1, MSG_CMSG_COMPAT) < 0)
            err(1, "sendmmsg");

        return 0;

    ip_tunnel: fix kernel panic with icmp_dest_unreach

    [ Upstream commit a622260254ee481747cceaaa8609985b29a31565 ]

    Daniel Petre reported crashes in icmp_dst_unreach() with following call
    graph:

    Daniel found a similar problem mentioned in
     http://lkml.indiana.edu/hypermail/linux/kernel/1007.0/00961.html

    And indeed this is the root cause : skb->cb[] contains data fooling IP
    stack.

    We must clear IPCB in ip_tunnel_xmit() sooner in case dst_link_failure()
    is called. Or else skb->cb[] might contain garbage from GSO segmentation
    layer.

    A similar fix was tested on linux-3.9, but gre code was refactored in
    linux-3.10. I'll send patches for stable kernels as well.

    Many thanks to Daniel for providing reports, patches and testing !

    netlabel: improve domain mapping validation

    [ Upstream commit 6b21e1b77d1a3d58ebfd513264c885695e8a0ba5 ]

    The net/netlabel/netlabel_domainhash.c:netlbl_domhsh_add() function
    does not properly validate new domain hash entries resulting in
    potential problems when an administrator attempts to add an invalid
    entry.  One such problem, as reported by Vlad Halilov, is a kernel
    BUG (found in netlabel_domainhash.c:netlbl_domhsh_audit_add()) when
    adding an IPv6 outbound mapping with a CIPSO configuration.

    This patch corrects this problem by adding the necessary validation
    code to netlbl_domhsh_add() via the newly created
    netlbl_domhsh_validate() function.

    Ideally this patch should also be pushed to the currently active
    -stable trees.

    __kvm_set_xcr function does the CPL check when set xcr. __kvm_set_xcr is
    called in two flows, one is invoked by guest, call stack shown as below,

      handle_xsetbv(or xsetbv_interception)
        kvm_set_xcr
          __kvm_set_xcr

    the other one is invoked by host, for example during system reset:

      kvm_arch_vcpu_ioctl
        kvm_vcpu_ioctl_x86_set_xcrs
          __kvm_set_xcr

    The former does need the CPL check, but the latter does not.

    tilepro: work around module link error with gcc 4.7

    commit 3cb3f839d306443f3d1e79b0bde1a2ad2c12b555 upstream.

    gcc 4.7.x is emitting calls to __ffsdi2 where previously
    it used to inline the appropriate ctz instructions.
    While this needs to be fixed in gcc, it's also easy to avoid
    having it cause build failures when building with those
    compilers by exporting __ffsdi2 to modules.

    ALSA: usb-audio: work around Android accessory firmware bug

    commit 342cda29343a6272c630f94ed56810a76740251b upstream.

    When the Android firmware enables the audio interfaces in accessory
    mode, it always declares in the control interface's baInterfaceNr array
    that interfaces 0 and 1 belong to the audio function.  However, the
    accessory interface itself, if also enabled, already is at index 0 and
    shifts the actual audio interface numbers to 1 and 2, which prevents the
    PCM streaming interface from being seen by the host driver.

    To get the PCM interface interface to work, detect when the descriptors
    point to the (for this driver useless) accessory interface, and redirect
    to the correct one.

ipv6: introdcue __ipv6_addr_needs_scope_id and ipv6_iface_scope_id helper functions

[net-next commit b7ef213ef65256168df83ddfbb8131ed9adc10f9]

__ipv6_addr_needs_scope_id checks if an ipv6 address needs to supply
a 'sin6_scope_id != 0'. 'sin6_scope_id != 0' was enforced in case
of link-local addresses. To support interface-local multicast these
checks had to be enhanced and are now consolidated into these new helper
functions.

v2:
a) migrated to struct ipv6_addr_props

v3:
a) reverted changes for ipv6_addr_props
b) test for address type instead of comparing scope

v4:
a) unchanged

net: ipv6: Add IPv6 support to the ping socket.

[backport of net-next 6d0bfe22611602f36617bc7aa2ffa1bbb2f54c67]

This adds the ability to send ICMPv6 echo requests without a
raw socket. The equivalent ability for ICMPv4 was added in
2011.

Instead of having separate code paths for IPv4 and IPv6, make
most of the code in net/ipv4/ping.c dual-stack and only add a
few IPv6-specific bits (like the protocol definition) to a new
net/ipv6/ping.c. Hopefully this will reduce divergence and/or
duplication of bugs in the future.

Caveats:

- Setting options via ancillary data (e.g., using IPV6_PKTINFO
  to specify the outgoing interface) is not yet supported.
- There are no separate security settings for IPv4 and IPv6;
  everything is controlled by /proc/net/ipv4/ping_group_range.
- The proc interface does not yet display IPv6 ping sockets
  properly.

Tested with a patched copy of ping6 and using raw socket calls.
Compiles and works with all of CONFIG_IPV6={n,m,y}.

ping: always initialize ->sin6_scope_id and ->sin6_flowinfo

[net-next commit c26d6b46da3ee86fa8a864347331e5513ca84c2b]

If we don't need scope id, we should initialize it to zero.
Same for ->sin6_flowinfo.

vfs: optimize inode cache access patterns

The inode structure layout is largely random, and some of the vfs paths
really do care.  The path lookup in particular is already quite D$
intensive, and profiles show that accessing the 'inode->i_op->xyz'
fields is quite costly.

We already optimized the dcache to not unnecessarily load the d_op
structure for members that are often NULL using the DCACHE_OP_xyz bits
in dentry->d_flags, and this does something very similar for the inode
ops that are used during pathname lookup.

It also re-orders the fields so that the fields accessed by 'stat' are
together at the beginning of the inode structure, and roughly in the
order accessed.

The effect of this seems to be in the 1-2% range for an empty kernel
"make -j" run (which is fairly kernel-intensive, mostly in filename
lookup), so it's visible.  The numbers are fairly noisy, though, and
likely depend a lot on exact microarchitecture.  So there's more tuning
to be done.
