* 'for-linus' of git://git.kernel.dk/linux-block:
  block: don't try Write Same from __blkdev_issue_zeroout

SELinux tries to support setting/clearing of /proc/pid/attr attributes
from the shell by ignoring terminating newlines and treating an
attribute value that begins with a NUL or newline as an attempt to
clear the attribute.  However, the test for clearing attributes has
always been wrong; it has an off-by-one error, and this could further
lead to reading past the end of the allocated buffer since commit
bb646cdb ("proc_pid_attr_write():
switch to memdup_user()").  Fix the off-by-one error.

Even with this fix, setting and clearing /proc/pid/attr attributes
from the shell is not straightforward since the interface does not
support multiple write() calls (so shells that write the value and
newline separately will set and then immediately clear the attribute,
requiring use of echo -n to set the attribute), whereas trying to use
echo -n "" to clear the attribute causes the shell to skip the
write() call altogether since POSIX says that a zero-length write
causes no side effects. Thus, one must use echo -n to set and echo
without -n to clear, as in the following example:
$ echo -n unconfined_u:object_r:user_home_t:s0 > /proc/$$/attr/fscreate
$ cat /proc/$$/attr/fscreate
unconfined_u:object_r:user_home_t:s0
$ echo "" > /proc/$$/attr/fscreate
$ cat /proc/$$/attr/fscreate

Note the use of /proc/$$ rather than /proc/self, as otherwise
the cat command will read its own attribute value, not that of the shell.

There are no users of this facility to my knowledge; possibly we
should just get rid of it.

UPDATE: Upon further investigation it appears that a local process
with the process:setfscreate permission can cause a kernel panic as a
result of this bug.  This patch fixes CVE-2017-2618.

Commit 6f29a130 ("sctp: sctp_addr_id2transport should verify the

But it didn't check af variable beforehand, once users pass an address
with family = 0 through sockopt, sctp_get_af_specific will return NULL
and NULL pointer dereference will be caused by af->sockaddr_len.

This patch is to fix it by returning NULL if af variable is NULL.

Splicing from TCP socket is vulnerable when a packet with URG flag is
received and stored into receive queue.

__tcp_splice_read() returns 0, and sk_wait_data() immediately
returns since there is the problematic skb in queue.

soft lockups.

   - Fix a memory hotplug failure condition that results from not

     default we align to 2M allocations that the memory hotplug code
     assumes, but if the administrator specifies a non-default
     4K-alignment then we can fail to correctly size the reservation.

   - A one line fix to improve the predictability of libnvdimm block
     device names. A common operation is to reconfigure /dev/pmem0 into
     a different mode. For example, a reconfiguration might set a new
     mode that reserves some of the capacity for a struct page memmap

     "/dev/pmem0.1" after the mode change and then back to /dev/pmem0

This does not seem to happen any more with gcc-7, but removing the ACCESS_ONCE
seems safe anyway and it avoids a serious issue for some people. I have verified
that with gcc-5.3.1, the object code we get is better in the new version
both with and without CONFIG_KASAN, as we no longer allocate a 1344 byte
stack frame for hns_dsaf_get_regs() but otherwise have practically identical
object code.

With gcc-7.0.0, removing ACCESS_ONCE has no effect, the object code is already
good either way.

This patch is probably not urgent to get into 4.11 as only KASAN=y builds
with certain compilers are affected, but I still think it makes sense to
backport into older kernels.

When for instance a mobile Linux device roams from one access point to
another with both APs sharing the same broadcast domain and a
multicast snooping switch in between:

1)    (c) <~~~> (AP1) <--[SSW]--> (AP2)

2)              (AP1) <--[SSW]--> (AP2) <~~~> (c)

Then currently IPv6 multicast packets will get lost for (c) until an
MLD Querier sends its next query message. The packet loss occurs
because upon roaming the Linux host so far stayed silent regarding
MLD and the snooping switch will therefore be unaware of the
multicast topology change for a while.

This patch fixes this by always resending MLD reports when an interface
change happens, for instance from NO-CARRIER to CARRIER state.

====================
A few simple fixes:
 * fix FILS AEAD cipher usage to use the correct AAD vectors
   and to use synchronous algorithms
 * fix using mesh HT operation data from userspace
 * fix adding mesh vendor elements to beacons & plink frames
====================

Dmitry reported use-after-free in ip6_datagram_recv_specific_ctl()

A similar bug was fixed in commit 8ce48623 ("ipv6: tcp: restore
IP6CB for pktoptions skbs"), but I missed another spot.

tcp_v6_syn_recv_sock() can indeed set np->pktoptions from ireq->pktopts

A previous change to fix checks for NL80211_MESHCONF_HT_OPMODE
missed setting the flag when replacing FILL_IN_MESH_PARAM_IF_SET
with checking codes. This results in dropping the received HT
operation value when called by nl80211_update_mesh_config(). Fix
this by setting the flag properly.

The function ieee80211_ie_split_vendor doesn't return 0 on errors. Instead
it returns any offset < ielen when WLAN_EID_VENDOR_SPECIFIC is found. The
return value in mesh_add_vendor_ies must therefore be checked against
ifmsh->ie_len and not 0. Otherwise all ifmsh->ie starting with
WLAN_EID_VENDOR_SPECIFIC will be rejected.

The skcipher could have been of the async variant which may return from
skcipher_encrypt() with -EINPROGRESS after having queued the request.
The FILS AEAD implementation here does not have code for dealing with
that possibility, so allocate a sync cipher explicitly to avoid
potential issues with hardware accelerators.

This is based on the patch sent out by Ard.

Incorrect num_elem parameter value (1 vs. 5) was used in the
aes_siv_encrypt() call. This resulted in only the first one of the five
AAD vectors to SIV getting included in calculation. This does not
protect all the contents correctly and would not interoperate with a
standard compliant implementation.

Fix this by using the correct number. A matching fix is needed in the AP
side (hostapd) to get FILS authentication working properly.
