When dumping generic netlink families, only the first dump call
is locked with genl_lock(), which protects the list of families,
and thus subsequent calls can access the data without locking,
racing against family addition/removal. This can cause a crash.
Fix it - the locking needs to be conditional because the first
time around it's already locked.
A similar bug was reported to me on an old kernel (3.4.47) but
the exact scenario that happened there is no longer possible,
on those kernels the first round wasn't locked either. Looking
at the current code I found the race described above, which had
also existed on the old kernel.

Probably this one is quite unlikely to be triggered, but it's more safe
to do the call_rcu() at the end after we have dropped the reference on
the asoc and freed sctp packet chunks. The reason why is because in
sctp_transport_destroy_rcu() the transport is being kfree()'d, and if
we're unlucky enough we could run into corrupted pointers. Probably
that's more of theoretical nature, but it's safer to have this simple fix.
Introduced by commit 8c98653f ("sctp: sctp_close: fix release of bindings
for deferred call_rcu's"). I also did the 8c98653f regression test and

This patch fixes a kernel panic that can occur when disconnecting a
wireless USB->serial device. When the serial device disconnects, the
device cleanup procedure ends up calling usb_hcd_disable_endpoint on the
serial device's endpoints. The wusbcore uses the ABORT_RPIPE command to
abort all transfers on the given endpoint but it does not properly give
back the URBs when the transfer results return from the HWA. This patch
prevents the transfer result processing code from bailing out when it sees
a WA_XFER_STATUS_ABORTED result code so that these urbs are flushed
properly by usb_hcd_disable_endpoint. It also updates wa_urb_dequeue to
handle the case where the endpoint has already been cleaned up when
usb_kill_urb is called which is where the panic originally occurred.

Since commits 4005ad4390 (EHCI: implement new semantics for
URB_ISO_ASAP) and c75c5ab575 (ALSA: USB: adjust for changed 3.8 USB
API) became widely distributed, people have been experiencing problems
with audio transfers. The slightest underrun causes complete failure,
requiring the audio stream to be restarted.
It turns out that the current isochronous API doesn't handle underruns
in the best way. The ALSA developers would much rather have transfers
that are submitted too late be accepted and complete in the normal
fashion, rather than being refused outright.
This patch implements the requested approach. When an isochronous URB
submission is so late that all its scheduled slots have already
expired, a debugging message will be printed in the log and the URB
will be accepted as usual. Assuming it was submitted by a completion
handler (which is normally the case), it will complete shortly
thereafter with all the usb_iso_packet_descriptor status fields marked
-EXDEV.
This fixes (for ehci-hcd)

load_microcode_amd() (and the helper it is using) should not have an
cpu parameter. The microcode loading does not depend on the CPU wrt the
patches loaded since they will end up in a global list for all CPUs
anyway.
The change from cpu to x86family in load_microcode_amd()
now allows to drop the code messing with cpu_data(cpu) from
collect_cpu_info_amd_early(), which is wrong anyway because at that
point the per-cpu cpu_info is not yet setup (These values would later be
overwritten by smp_store_boot_cpu_info() / smp_store_cpu_info()).
Fold the rest of collect_cpu_info_amd_early() into load_ucode_amd_ap(),
because its only used at one place and without the cpuinfo_x86 accesses
it was not much left.

cpu_has_amd_erratum() is buggy, because it uses the per-cpu cpu_info
before it is filled by smp_store_boot_cpu_info() / smp_store_cpu_info().
If early microcode loading is enabled its collect_cpu_info_amd_early()
will fill ->x86 and so the fallback to boot_cpu_data is not used. But
->x86_vendor was not filled and is still X86_VENDOR_INTEL resulting in
no errata fixes getting applied and my system hangs on boot.
Using cpu_info in cpu_has_amd_erratum() is wrong anyway: its only
caller init_amd() will have a struct cpuinfo_x86 as parameter and the
set_cpu_bug() that is controlled by cpu_has_amd_erratum() also only uses
that struct.
So pass the struct cpuinfo_x86 from init_amd() to cpu_has_amd_erratum()
and the broken fallback can be dropped.

The motivation of adding __ext4_journal_stop() into

improve error reporting. So replace __ext4_journal_stop() with
ext4_journal_abort_handle() which was there before that commit and add

"This is three bug fixes: An fnic warning caused by sleeping under a
lock, a major regression with our updated WRITE SAME/UNMAP logic which
caused tons of USB devices (and one RAID card) to cease to function
and a megaraid_sas firmware initialisation problem which causes kdump
failures"

Merge tag 'samsung-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
From Kukjin Kim:
Fix to boot kernel on exynos5440 which has no specific map_io(). Current kernel
cannot support no CPU specific map_io() for Samsung SoCs.
* tag 'samsung-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
ARM: SAMSUNG: fix to support for missing cpu specific map_io
Signed-off-by: Olof Johansson <olof@lixom.net>
Pull powerpc fixes from Ben Herrenschmidt:
"This includes small series from Michael Neuling to fix a couple of
nasty remaining problems with the new Power8 support, also targeted at
stable 3.10, without which some new userspace accessible registers
aren't properly context switched, and in some case, can be clobbered
by the user of transactional memory.
Along with that, a few slightly more minor things, such as a missing
Kconfig option to enable handling of denorm exceptions when not
running under a hypervisor (or userspace will randomly crash when
hitting denorms with the vector unit), some nasty bugs in the new
pstore oops code, and other simple bug fixes worth having in now.
Note: I picked up the two powerpc KVM fixes as Alex Graf asked me to
handle KVM bits while he is on vacation. However I'll let him decide
whether they should go to -stable or not when he is back"
