git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:
- Unbreak parisc bootloader by avoiding a gcc-7 optimization to convert
multiple byte-accesses into one word-access.
- Add missing HWPOISON page fault handler code. I completely missed
that when I added HWPOISON support during this merge window and it
only showed up now with the madvise07 LTP test case.
- Fix backtrace unwinding to stop when stack start has been reached.
- Issue warning if initrd has been loaded into memory regions with
broken RAM modules.
- Fix HPMC handler (parisc hardware fault handler) to comply with
architecture specification.
- Avoid compiler warnings about too large frame sizes.
- Minor init-section fixes.

gcc-7 optimizes the byte-wise accesses of get_unaligned_le32() into
word-wise accesses if the 32-bit integer output_len is declared as
external. This panics then the bootloader since we don't have the
unaligned access fault trap handler installed during boot time.
Avoid this optimization by declaring output_len as byte-aligned and thus
unbreak the bootloader code.
Additionally, compile the boot code optimized for size.

By adding the feature to build the kernel as self-extracting
executeable, the possibility to simply compress the kernel with gzip was
lost.
This patch now reintroduces this possibilty again and leaves it up to
the user to decide how the kernel should be built.
The palo bootloader is able to natively load both formats.

Commit 24587380f61d ("parisc: Add MADV_HWPOISON and MADV_SOFT_OFFLINE") added
the necessary constants to handle hardware-poisoning. Those were needed to
support the page deallocation feature from firmware.
But I completely missed to add the relevant fault handler code. This now
showed up when I ran the madvise07 testcase from the Linux Test Project,
which failed with a kernel BUG at arch/parisc/mm/fault.c:320.
With this patch the parisc kernel now behaves like other platforms and
gives the same kernel syslog warnings when poisoning pages.

According to the programming note at page 1-31 of the PA 1.1 Firmware
Architecture document, one should use the PDC_INSTR firmware function to
get the instruction that invokes a PDCE_CHECK in the HPMC handler. This
patch follows this note and sets the instruction which has been a nop up
until now.
Testing on a C3000 and C8000 showed that this firmware call isn't
implemented on those machines, so maybe it's only needed on older ones.

The parisc architecture has larger stack frames than most other
architectures on 32-bit kernels.
Increase the maximum allowed stack frame to 1280 bytes for parisc to
avoid warnings in the do_sys_poll() and pat_memconfig() functions.

This patch fixes a memory leak issue when alloc_mr is used.
mr->pages and mr->npages are used only in alloc_mr path. mr->pages
is allocated when alloc_mr is called or in the case of FRMR, while
creating the MR. mr->npages is updated only when the MR created
is used i.e. after invoking map_mr_sg verb, before data transfer.
In the dereg_mr path, if mr->npages is 0, driver ends up not freeing
the memory created.
Removing the npages check from the dereg_mr path for kernel consumers.

When there is a NETDEV_UNREGISTER event, bnxt_re driver calls
ib_unregister_device() (RTNL lock held).
ib_unregister_device attempts to flush a worker queue scheduled by
ib_core and that queue might have a pending ib_query_port().
ib_query_port in turn calls bnxt_re_query_port(), which while querying the
link speed using ib_get_eth_speed(), tries to acquire the rtnl_lock() which
was already held by NETDEV_UNREGISTER.
Fixing the issue by removing the link speed query from bnxt_re_query_port()
Now the speed is queried post a successful ib_register_device or whenever
there is a NETDEV_CHANGE event.

Upon receipt of the NETDEV_REGISTER event from the netdev notifier chain,
the IB stack registration is spawned off to a workqueue since that also
requires an rtnl lock.
There could be 2 kinds of races between the NETDEV_REGISTER and the
NETDEV_UNREGISTER event handling.
a)The NETDEV_UNREGISTER event is received in rapid succession after
the NETDEV_REGISTER event even before the work queue got a chance to run.
b)The NETDEV_UNREGISTER event is received while the workqueue that handles
registration with the IB stack is still in progress.
Handle both the races with a bit flag that is set just before the work item
is queued and cleared in the workqueue after the event is handled just
before the workqueue item is freed.
While adding the new flag, it was noted that the flags are all used in
*_bit() operations which expect a bit number and not a literal constant
with a bit set. So change the numbers to be bit numbers.

Once a cmd to FW times out(after 20s) it is reasonable to
assume the FW or atleast the control path is dead.
No point issuing further cmds to the FW as each subsequent cmd
with another 20s timeout will cascade resulting in unnecessary
traces and/or NMI Lockups.

During OpenMPI scale up testing, we observe rdma_connect
failures if ports are reused on multiple connections.
This is because the Control Queue-Pair (CQP) command to add
the reused port to Accelerated Port Bit VectorTable (APBVT)
fails as there already exists an entry.
Check for duplicate port before invoking the CQP command
to add APBVT entry and delete the entry only if the port
is not in use.

Netdev event notifier registration/de-registration is not
synchronized with a lock and there is a possibility of a
duplicate registration of notifier before the unregister
completes.
Register netdev event notifiers during module init and
de-register them at module exit.
This avoids the need to tie the registration to first netdev
client interface open and de-registration to last client
interface close and the synchronization to achieve it.
This also fixes a crash due to duplicate registration.

If delay_drop_debugfs_init() fails in any of the operations to create
debugfs, it is calling delay_drop_debugfs_cleanup() as part of its
cleanup. But delay_drop_debugfs_cleanup() checks for 'dbg' and since
we have not yet pointed 'dbg' to the debugfs we need to cleanup, the
cleanup fails and we are left with stray debugfs elements and also a
memory leak.

In the case where mbox_status is OCRDMA_MBX_STATUS_FAILED and
add_status is OCRDMA_MBX_STATUS_FAILED err_num is assigned -EAGAIN
however the case OCRDMA_MBX_STATUS_FAILED is missing a break and
falls through to the default case which then re-assigns err_num
to -EFAULT. Fix this so that err_num is assigned to -EAGAIN
for the add_status OCRDMA_MBX_STATUS_FAILED case and -EFAULT
otherwise.

If a listen create fails, then the server tid (stid) is incorrectly left
in the stid idr table, which can cause a touch-after-free if the stid
is looked up and the already freed endpoint is touched. So make sure

Josef Bacik says:
====================
net: fix reuseaddr regression
I introduced a regression when reworking the fastreuse port stuff that allows
bind conflicts to occur once a reuseaddr successfully opens on an existing tb.
The root cause is I reversed an if statement which caused us to set the tb as if
there were no owners on the socket if there were, which obviously is not
correct.
Dave could you please queue these changes up for -stable, I've run them through
the net tests and added another test to check for this problem specifically.

When doing my reuseport rework I screwed up and changed a
if (hlist_empty(&tb->owners))
to
if (!hlist_empty(&tb->owners))
This is obviously bad as all of the reuseport/reuse logic was reversed,
which caused weird problems like allowing an ipv4 bind conflict if we
opened an ipv4 only socket on a port followed by an ipv6 only socket on
the same port.

In ipv6_rcv_saddr_equal() we need to use inet6_rcv_saddr(sk) for the

the proper comparisons.

Zerocopy skbs frags are copied when the skb is looped to a local sock.
Commit 1080e512d44d ("net: orphan frags on receive") introduced calls
to skb_orphan_frags to deliver_skb and __netif_receive_skb for this.
With msg_zerocopy, these skbs can also exist in the tx path and thus
loop from dev_queue_xmit_nit. This already calls deliver_skb in its
loop. But it does not orphan before a separate pt_prev->func().
Add the missing skb_orphan_frags_rx.

In linux-4.13, Wei worked hard to convert dst to a traditional
refcounted model, removing GC.
We now want to make sure a dst refcount can not transition from 0 back
to 1.
The problem here is that input path attached a not refcounted dst to an
skb. Then later, because packet is forwarded and hits skb_dst_force()
before exiting RCU section, we might try to take a refcount on one dst
that is about to be freed, if another cpu saw 1 -> 0 transition in
dst_release() and queued the dst for freeing after one RCU grace period.
Lets unify skb_dst_force() and skb_dst_force_safe(), since we should
always perform the complete check against dst refcount, and not assume
it is not zero.

Similarly dst_clone() can use dst_hold() helper to have additional
debugging, as a follow up to commit 44ebe79149ff ("net: add debug
atomic_inc_not_zero() in dst_hold()")
In net-next we will convert dst atomic_t to refcount_t for peace of
mind.

Given NR_IRQS is 2048 on sparc64, and even 32784 on alpha, 3 digits is
not enough to represent interrupt numbers on all architectures. Hence
PHY interrupt numbers may be truncated during printing.
Increase the buffer size from 4 to 8 bytes to fix this.

The number of outstanding work requests is limited. If all work
requests are in use, tx processing is postponed to another scheduling
of the tx worker. Switch to a delayed worker to have a gap for tx

An out-of-sync condition can just be detected by the client.
If the server receives a CLC DECLINE message indicating an out-of-sync
condition for the link groups, the server must clean up the out-of-sync
link group.
There is no need for an extra third parameter in smc_clc_send_decline().
