When tcp_sk_init() failed in inet_ctl_sock_create(),
'net->ipv4.tcp_congestion_control' will be left
uninitialized, but tcp_sk_exit() hasn't check for
that.
This patch add checking on 'net->ipv4.tcp_congestion_control'

Pull aio race fixes and cleanups from Al Viro.
The aio code had more issues with error handling and races with the aio
completing at just the right (wrong) time along with freeing the file
descriptor when another thread closes the file.
Just a couple of these commits are the actual fixes: the others are
cleanups to either make the fixes simpler, or to make the code legible
and understandable enough that we hope there's no more fundamental races
hiding.
* 'work.aio' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
aio: move sanity checks and request allocation to io_submit_one()
deal with get_reqs_available() in aio_get_req() itself
aio: move dropping ->ki_eventfd into iocb_destroy()
make aio_read()/aio_write() return int
Fix aio_poll() races
aio: store event at final iocb_put()
aio: keep io_event in aio_kiocb
aio: fold lookup_kiocb() into its sole caller
pin iocb through aio.

work, there is no interrupt when touching the touchpad, after

symlink body shouldn't be freed without an RCU delay. Switch debugfs to

body in the callback. Similar to solution for bpf, only here it's even
more obvious that ->evict_inode() can be dropped.

It was supposed to be fixed on commit 974cb0e3e7 ("tipc: fix uninit-value
in tipc_nl_compat_name_table_dump") by checking TLV_GET_DATA_LEN(msg->req)
in cmd->header()/tipc_nl_compat_name_table_dump_header(), which is called
ahead of tipc_nl_compat_name_table_dump().
However, tipc_nl_compat_dumpit() doesn't handle the error returned from cmd
header function. It means even when the check added in that fix fails, it
won't stop calling tipc_nl_compat_name_table_dump(), and the issue will be
triggered again.
So this patch is to add the process for the err returned from cmd header
function in tipc_nl_compat_dumpit().

net: stmmac: fix handling of oversized frames
I accidentally had MTU size mismatch (9000 vs. 1500) in my network,
and I noticed I could kill a system using stmmac & 1500 MTU simply
by pinging it with "ping -s 2000 ...".
While testing a fix I encountered also some other issues that need fixing.
I have tested these only with enhanced descriptors, so the normal
descriptor changes need a careful review.

Packets without the last descriptor set should be dropped early. If we
receive a frame larger than the DMA buffer, the HW will continue using the
next descriptor. Driver mistakes these as individual frames, and sometimes
a truncated frame (without the LD set) may look like a valid packet.
This fixes a strange issue where the system replies to 4098-byte ping
although the MTU/DMA buffer size is set to 4096, and yet at the same
time it's logging an oversized packet.

If we have error bits set, the discard_frame status will get overwritten
by checksum bit checks, which might set the status back to good one.
Fix by checking the COE status only if the frame is good.

Currently, if we drop a packet, we exit from NAPI loop before the budget
is consumed. In some situations this will make the RX processing stall
e.g. when flood pinging the system with oversized packets, as the
errorneous packets are not dropped efficiently.
If we drop a packet, we should just continue to the next one as long as
the budget allows.

We always program the maximum DMA buffer size into the receive descriptor,
although the allocated size may be less. E.g. with the default MTU size
we allocate only 1536 bytes. If somebody sends us a bigger frame, then
memory may get corrupted.
Fix by using exact buffer sizes.

If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example
# cat device_name
# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32
I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.
This is also preparation for future patches.

It was reported that re-introducing ASPM, in combination with RX
interrupt coalescing, results in significantly increased packet
latency, see [0]. Disabling ASPM or RX interrupt coalescing fixes
the issue. Therefore change the driver's default to disable RX
interrupt coalescing. Users still have the option to enable RX
coalescing via ethtool.

Here are some small staging driver fixes for 5.1-rc3, and one driver
removal.
The biggest thing here is the removal of the mt7621-eth driver as a
"real" network driver was merged in 5.1-rc1 for this hardware, so this
old driver can now be removed.
Other than that, there are just a number of small fixes, all resolving
reported issues and some potential corner cases for error handling
paths.
All of these have been in linux-next with no reported issues.

Here is a single driver core patch for 5.1-rc3.
After 5.1-rc1, all of the users of BUS_ATTR() are finally removed, so we
can now drop this macro from include/linux/device.h so that no more new
users will be created.
This patch has been in linux-next for a while, with no reported issues.

Merge tag 'driver-core-5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fix from Greg KH:
"Here is a single driver core patch for 5.1-rc3.
After 5.1-rc1, all of the users of BUS_ATTR() are finally removed, so
we can now drop this macro from include/linux/device.h so that no more
new users will be created.
This patch has been in linux-next for a while, with no reported
issues"

driver core: remove BUS_ATTR()
Here are some binder, habanalabs, and vboxguest driver fixes for
5.1-rc3.
The Binder fixes resolve some reported issues found by testing, first by
the selinux developers, and then earlier today by syzbot.
The habanalabs fixes are all minor, resolving a number of tiny things.
The vboxguest patches are a bit larger. They resolve the fact that
virtual box decided to change their api in their latest release in a way
that broke the existing kernel code, despite saying that they were never
going to do that. So this is a bit of a "new feature", but is good to
get merged so that 5.1 will work with the latest release. The changes
are not large and of course virtual box "swears" they will not break
this again, but no one is holding their breath here.
All of these have been in linux-next for a while with no reported
issues.

13 Fixes, 7 of which are for IBM fibre channel and three additional
for fairly serious bugs in drivers (qla2xxx, mpt3sas, aacraid). Of
the three core fixes, the most significant is probably the missed run
queue causing an indefinite hang. The others are fixing a potential
use after free on device close and silencing an incorrect warning.
