The commit fe3475af3b ("net: rds: add per rds connection cache
statistics") adds cache_allocs in struct rds_info_rdma_connection
as below:
struct rds_info_rdma_connection {
...
__u32 rdma_mr_max;
__u32 rdma_mr_size;
__u8 tos;
__u32 cache_allocs;
};
The peer struct in rds-tools of struct rds_info_rdma_connection is as
below:
struct rds_info_rdma_connection {
...
uint32_t rdma_mr_max;
uint32_t rdma_mr_size;
uint8_t tos;
uint8_t sl;
uint32_t cache_allocs;
};
The difference between userspace and kernel is the member variable sl.
In the kernel struct, the member variable sl is missing. This will
introduce risks. So it is necessary to use this commit to avoid this risk.

An excerpt from netlink(7) man page,
In multipart messages (multiple nlmsghdr headers with associated payload
in one byte stream) the first and all following headers have the
NLM_F_MULTI flag set, except for the last header which has the type
NLMSG_DONE.
but, after (ee28906) there is a missing NLM_F_MULTI flag in the middle of a
FIB dump. The result is user space applications following above man page
excerpt may get confused and may stop parsing msg believing something went
wrong.
In the golang netlink lib [0] the library logic stops parsing believing the
message is not a multipart message. Found this running Cilium[1] against
net-next while adding a feature to auto-detect routes. I noticed with
multiple route tables we no longer could detect the default routes on net
tree kernels because the library logic was not returning them.
Fix this by handling the fib_dump_info_fnhe() case the same way the
fib_dump_info() handles it by passing the flags argument through the
call chain and adding a flags argument to rt_fill_info().
Tested with Cilium stack and auto-detection of routes works again. Also
annotated libs to dump netlink msgs and inspected NLM_F_MULTI and
NLMSG_DONE flags look correct after this.
Note: In inet_rtm_getroute() pass rt_fill_info() '0' for flags the same
as is done for fib_dump_info() so this looks correct to me.

100GbE Intel Wired LAN Driver Updates 2019-08-23
This series contains updates to ice driver only.
Dave adds logic for the necessary bits to be set in the VSI context for
the PF_VSI and the TX_descriptors for control packets egressing the
PF_VSI. Updated the logic to detect both DCBx and LLDP states in the
firmware engine to account for situations where DCBx is enabled and LLDP
is disabled. Fixed the driver to treat the DCBx state of "NOT_STARTED"
as a valid state and should not assume "is_fw_lldp" true automatically.
Since "enable-fw-lldp" flag was confusing and cumbersome, change the
flag to "fw-lldp-agent" with a value of on or off to help clarify
whether the LLDP agent is running or not.
Brett fixes an issue where synchronize_irq() was being called from the
host of VF's, which should not be done.
Michal fixed an issue when rebuilding the DCBx configuration while in
IEEE mode versus CEE mode, so add a check before copying the
configuration value to ensure we are only in CEE mode.
Jake fixes the PF to reject any VF request to setup head writeback since
the support has been deprecated.
Mitch adds an additional check to ensure the VF is active before sending
out an error message that a message was unable to be sent to a
particular VF.
Chinh updates the driver to use "topology" mode when checking the PHY
for status, since this mode provides us the current module type that is
available. Fixes the driver from clearing the auto_fec_enable bit which
was blocking a user from forcing non-spec compliant FEC configurations.
Amruth does a refactor on the code to first check, then assign in the
virtual channel space.
Bruce updates the driver to actually update the stats when a user runs
the ethtool command 'ethtool -S <iface>' instead of providing a snapshot
of the stats that maybe from a second ago.
Akeem fixes up the adding/removing of VSI MAC filters for VFs, so that
VFs cannot add/remove a filter from another VSI. We now track the
number of filters added right from when the VF resources get allocated
and won't get into MAC filter mis-match issue in the switch.

IQD devices offer limited support for bulking: all frames in a TX buffer
need to have the same target. qeth_iqd_may_bulk() implements this
constraint, and allows us to defer the TX doorbell until
(a) the buffer is full (since each buffer needs its own doorbell), or
(b) the entire TX queue is full, or
(b) we reached the BQL limit.

Due to their large MTU and potentially low utilization of TX buffers,
IQD devices in particular require fast TX recycling. This makes them
a prime candidate for a TX NAPI path in qeth.
qeth_tx_poll() uses the recently introduced qdio_inspect_queue() helper
to poll the TX queue for completed buffers. To avoid hogging the CPU for
too long, we yield to the stack after completing an entire queue's worth
of buffers.
While IQD is expected to transfer its buffers synchronously (and thus
doesn't support TX interrupts), a timer covers for the odd case where a
TX buffer doesn't complete synchronously. Currently this timer should
only ever fire for
(1) the mcast queue,
(2) the occasional race, where the NAPI poll code observes an update to
queue->used_buffers while the TX doorbell hasn't been issued yet.

This consolidates the SW statistics code, and improves it to
(1) account for the header overhead of each segment on a TSO skb,
(2) count dangling packets as in-error (during eg. shutdown), and
(3) only count offloads when the skb was successfully transmitted.
We also count each segment of an TSO skb as one packet - except for
tx_dropped, to be consistent with dev->tx_dropped.

If a driver wants to use the new Output Queue poll code, then the qdio
layer must disable its internal Queue scanning. Let the driver select
this mode by passing a special scan_threshold of 0.
As the scan_threshold is the same for all Output Queues, also move it
into the main qdio_irq struct. This allows for fast opt-out checking, a
driver is expected to operate either _all_ or none of its Output Queues
in polling mode.

Factor out a helper that scans a single QDIO Queue, so that qeth can
implement TX NAPI on top of it.
While doing so, remove the duplicated tracking of the next-to-scan index

qdio_handle_aobs() needs to move slightly upwards in the code hierarchy,

Recent commit added logic to determine the appropriate statistics block
size to allocate and the size is stored in bp->hw_ring_stats_size. But
if the firmware spec is older than 1.6.0, it is 0 and not initialized.
This causes the allocation to fail with size 0 and bnxt_open() to
abort. Fix it by always initializing bp->hw_ring_stats_size to the
legacy default size value.

Commit d4c08afafa ("s390/qeth: streamline SNMP cmd code") removed
the bounds checking for req_len, under the assumption that the check in
qeth_alloc_cmd() would suffice.
But that code path isn't sufficiently robust to handle a user-provided
data_length, which could overflow (when adding the cmd header overhead)
before being checked against QETH_BUFSIZE. We end up allocating just a
tiny iob, and the subsequent copy_from_user() writes past the end of
that iob.
Special-case this path and add a coarse bounds check, to protect against
maliciuous requests. This let's the subsequent code flow do its normal
job and precise checking, without risk of overflow.

In decode_session{4,6} there is a possibility that the skb dst dev is NULL,
e,g, with tunnel collect_md mode, which will cause kernel crash.
Here is what the code path looks like, for GRE:
- ip6gre_tunnel_xmit
- ip6gre_xmit_ipv6
- __gre6_xmit
- ip6_tnl_xmit
- if skb->len - t->tun_hlen - eth_hlen > mtu; return -EMSGSIZE
- icmpv6_send
- icmpv6_route_lookup
- xfrm_decode_session_reverse
- decode_session4
- oif = skb_dst(skb)->dev->ifindex; <-- here
- decode_session6
- oif = skb_dst(skb)->dev->ifindex; <-- here
The reason is __metadata_dst_init() init dst->dev to NULL by default.
We could not fix it in __metadata_dst_init() as there is no dev supplied.
On the other hand, the skb_dst(skb)->dev is actually not needed as we
called decode_session{4,6} via xfrm_decode_session_reverse(), so oif is not
used by: fl4->flowi4_oif = reverse ? skb->skb_iif : oif;
So make a dst dev check here should be clean and safe.
v4: No changes.
v3: No changes.
v2: fix the issue in decode_session{4,6} instead of updating shared dst dev
in {ip_md, ip6}_tunnel_xmit.

In preparation for adding newer V2 parts that use a FIFO,
reorganize altera_cvp_chk_error() and change the write
function to block based.
V2 parts have a block size matching the FIFO while older
V1 parts write a 32 bit word at a time.

Newer Intel FPGAs have different Vendor Specific offsets than
legacy parts. Use PCI discovery to find the CvP registers.
Since the register positions remain the same, change the hard
coded address to a more flexible way of indexing registers
from the offset.
Adding new PCI read and write abstraction functions to
handle the offset (altera_read_config_dword() and
altera_write_config_dword()).

Unusually, we're routing them via the arm64 tree as per Paolo's

We don't actually have any other arm64 fixes pending at the moment
(touch wood), so I've pulled from Marc, written a merge commit, tagged
the result and run it through my build/boot/bisect scripts"
