MIPS: Implement __multi3 for GCC7 MIPS64r6 builds
Linux 4.9.86
Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
commit ebabcf17bc upstream.
GCC7 is a bit too eager to generate suboptimal __multi3 calls (128bit
multiply with 128bit result) for MIPS64r6 builds, even in code which
doesn't explicitly use 128bit types, such as the following:
unsigned long func(unsigned long a, unsigned long b)
{
return a > (~0UL) / b;
}
Which GCC rearanges to:
return (unsigned __int128)a * (unsigned __int128)b > 0xffffffffffffffff;
Therefore implement __multi3, but only for MIPS64r6 with GCC7 as under
normal circumstances we wouldn't expect any calls to __multi3 to be
generated from kernel code.

check for "Invalid VF id". Currently, the check is done against max_vfs.
However, the user doesn't always create max_vfs. So, the check should be
against the created number of VFs. The number of bnxt_vf_info structures
that are allocated in bnxt_alloc_vf_resources routine is the "number of
requested VFs". So, if an "invalid VF id" falls between the requested
number of VFs and the max_vfs, the driver will be dereferencing an invalid

[ Upstream commit 248de22e63 ]
The original code for __i40e_chk_linearize didn't take into account the
fact that if a fragment is 16K in size or larger it has to be split over 2
descriptors and the smaller of those 2 descriptors will be on the trailing
edge of the transmit. As a result we can get into situations where we didn't
catch requests that could result in a Tx hang.
This patch takes care of that by subtracting the length of all but the
trailing edge of the stale fragment before we test for sum. By doing this
we can guarantee that we have all cases covered, including the case of a
fragment that spans multiple descriptors. We don't need to worry about
checking the inner portions of this since 12K is the maximum aligned DMA
size and that is larger than any MSS will ever be since the MTU limit for
jumbos is something on the order of 9K.

[ Upstream commit c0bace7984 ]
libc-compat.h aims to prevent symbol collisions between uapi and libc
headers for each supported libc. This requires continuous coordination
between them.
The goal of this commit is to improve the situation for libcs (such as
musl) which are not yet supported and/or do not wish to be explicitly
supported, while not affecting supported libcs. More precisely, with
this commit, unsupported libcs can request the suppression of any
specific uapi definition by defining the correspondings _UAPI_DEF_*
macro as 0. This can fix symbol collisions for them, as long as the
libc headers are included before the uapi headers. Inclusion in the
other order is outside the scope of this commit.
All infrastructure in order to enable this fallback for unsupported
libcs is already in place, except that libc-compat.h unconditionally
defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that
any previous definitions are ignored. In order to fix this, this commit
merely makes these definitions conditional.
This commit together with the musl libc commit
http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258
fixes for example the following compiler errors when <linux/in6.h> is
included after musl's <netinet/in.h>:
./linux/in6.h:32:8: error: redefinition of 'struct in6_addr'
./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6'
./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq'

When using enhanced mode for IPoIB, two threads may execute xmit in
parallel to two different TX queues while the target is the same.
In this case, both of them will add the same neighbor to the path's
neigh link list and we might see the following message:
list_add double add: new=ffff88024767a348, prev=ffff88024767a348...

__dev_queue_xmit+0x55/0xb10
Analysis:
Two SKB are scheduled to be transmitted from two cores.
In ipoib_start_xmit, both gets NULL when calling ipoib_neigh_get.
Two calls to neigh_add_path are made. One thread takes the spin-lock
and calls ipoib_neigh_alloc which creates the neigh structure,
then (after the __path_find) the neigh is added to the path's neigh
link list. When the second thread enters the critical section it also
calls ipoib_neigh_alloc but in this case it gets the already allocated
ipoib_neigh structure, which is already linked to the path's neigh
link list and adds it again to the list. Which beside of triggering
the list, it creates a loop in the linked list. This loop leads to
endless loop inside path_rec_completion.
Solution:
Check list_empty(&neigh->list) before adding to the list.
Add a similar fix in "ipoib_multicast.c::ipoib_mcast_send"

We store per path and per device configuration data to identify the
path or device correctly. The per path configuration data might get
mixed up if the original request gets into error recovery and is
started with a random path mask.
This would lead to a wrong identification of a path in case of a CUIR
event for example.
Fix by copying the path mask from the original request to the error
recovery request in case it is a path verification request.

While in recovery process of PCI error (called EEH on PowerPC arch),
another PCI transaction could be corrupted causing a situation of
nested PCI errors. Also, this scenario could be reproduced with
error injection mechanisms (for debug purposes).
We observe that in case of nested PCI errors, bnx2x might attempt to
initialize its shmem and cause a kernel crash due to bad addresses
read from MCP. Multiple different stack traces were observed depending
on the point the second PCI error happens.
This patch avoids the crashes by:
* failing PCI recovery in case of nested errors (since multiple
PCI errors in a row are not expected to lead to a functional
adapter anyway), and by,
* preventing access to adapter FW when MCP is failed (we mark it as
failed when shmem cannot get initialized properly).

[ Upstream commit bbc25bee37 ]
Current MIPS64r6 toolchains aren't able to generate efficient
DMULU/DMUHU based code for the C implementation of umul_ppmm(), which
performs an unsigned 64 x 64 bit multiply and returns the upper and
lower 64-bit halves of the 128-bit result. Instead it widens the 64-bit
inputs to 128-bits and emits a __multi3 intrinsic call to perform a 128
x 128 multiply. This is both inefficient, and it results in a link error
since we don't include __multi3 in MIPS linux.
For example commit 90a53e4432 ("cfg80211: implement regdb signature
checking") merged in v4.15-rc1 recently broke the 64r6_defconfig and

[ Upstream commit d1b8b2391c ]
When an I/O is returned with an srb_status of SRB_STATUS_INVALID_LUN
which has zero good_bytes it must be assigned an error. Otherwise the
I/O will be continuously requeued and will cause a deadlock in the case
where disks are being hot added and removed. sd_probe_async will wait
forever for its I/O to complete while holding scsi_sd_probe_domain.
Also returning the default error of DID_TARGET_FAILURE causes multipath
to not retry the I/O resulting in applications receiving I/O errors
before a failover can occur.

[ Upstream commit c9fefa0819 ]
Now it's using IPV6_MIN_MTU as the min mtu in ip6_tnl_xmit, but
IPV6_MIN_MTU actually only works when the inner packet is ipv6.
With IPV6_MIN_MTU for ipv4 packets, the new pmtu for inner dst
couldn't be set less than 1280. It would cause tx_err and the
packet to be dropped when the outer dst pmtu is close to 1280.
Jianlin found it by running ipv4 traffic with the topo:
(client) gre6 <---> eth1 (route) eth2 <---> gre6 (server)
After changing eth2 mtu to 1300, the performance became very
low, or the connection was even broken. The issue also affects
ip4ip6 and ip6ip6 tunnels.
So if the inner packet is ipv4, 576 should be considered as the
min mtu.
Note that for ip4ip6 and ip6ip6 tunnels, the inner packet can
only be ipv4 or ipv6, but for gre6 tunnel, it may also be ARP.
This patch using 576 as the min mtu for non-ipv6 packet works
for all those cases.

The current solution would setup fixed and force link of 1Gbps to the both
GMAC on the default. However, The GMAC should always be put to link down
state when the GMAC is disabled on certain target boards. Otherwise,
the driver possibly receives unexpected data from the floating hardware

certain protection in RX path to get rid of such kind of unexpected data
sent to the upper stack.

The only part of atmel_spi_remove which needs to be atomic is hardware
reset.
atmel_spi_stop_dma calls dma_terminate_all and this needs interrupts
enabled.
atmel_spi_release_dma calls dma_release_channel and dma_release_channel
locks a mutex inside of spin_lock.
So the call of these functions can't be inside a spin_lock.

Up to f5caf621ee ("x86/asm: Fix inline asm call constraints for Clang")
we were able to use x86 headers to build to the 'bpf' clang target, as
done by the BPF code in tools/perf/.
With that commit, we ended up with following failure for 'perf test LLVM', this
is because "clang ... -target bpf ..." fails since 4.0 does not have bpf inline
asm support and 6.0 does not recognize the register 'esp', fix it by guarding
that part with an #ifndef __BPF__, that is defined by clang when building to
the "bpf" target.

However, the fixup still get the err_ptr by add #8*4 to sp, which

[ Upstream commit 588753f1eb ]
One example of when an ICMPv6 packet is required to be looped back is
when a host acts as both a Multicast Listener and a Multicast Router.
A Multicast Router will listen on address ff02::16 for MLDv2 messages.
Currently, MLDv2 messages originating from a Multicast Listener running
on the same host as the Multicast Router are not being delivered to the
Multicast Router. This is due to dst.input being assigned the default
value of dst_discard.
This results in the packet being looped back but discarded before being
delivered to the Multicast Router.
This patch sets dst.input to ip6_input to ensure a looped back packet
is delivered to the Multicast Router.
