PCM buffers might be allocated dynamically when the buffer
preallocation failed or a larger buffer is requested, and it's not
guaranteed that substream->dma_buffer points to the actually used
buffer. The driver needs to refer to substream->runtime->dma_addr
instead for the buffer address.

Commit 13511704f8 ("net: taprio offload: enforce qdisc to netdev queue mapping")
resulted in duplicate entries in the qdisc hash.
While this did not impact the overall operation of the qdisc and taprio
code paths, it did result in an infinite loop when dumping the qdisc
properties, at least on one target (NXP LS1028 ARDB).
Removing the duplicate call to qdisc_hash_add() solves the problem.

Members of struct "llq" will be zero-inited, apart from member max_n_shift.
But we write llq.val straight after the init, so it was pointless to zero
init those other members. As such, separately init member max_n_shift
only.
In addition, struct "head" is initialised to "llq" only so that member
max_n_shift is set. But that member is never referenced for "head", so
remove any init there.
Removing these initializations is seen as a small performance optimisation,
as this code is (very) hot path.

This adds 'template 'tables' for ebtables.
Each ebtable_foo registers the table as a template, with an init function
that gets called once the first get/setsockopt call is made.
ebtables core then searches the (per netns) list of tables.
If no table is found, it searches the list of templates instead.
If a template entry exists, the init function is called which will
enable the table and register the hooks (so packets are diverted
to the table).
If no entry is found in the template list, request_module is called.
After this, hook registration is delayed until the 'ebtables'
(set/getsockopt) request is made for a given table and will only
happen in the specific namespace.

Some time ago, I reported a calltrace issue
"did not find a suitable aggregator", please see[1].
After a period of analysis and reproduction, I find
that this problem is caused by concurrency.
Before the problem occurs, the bond structure is like follows:
bond0 - slaver0(eth0) - agg0.lag_ports -> port0 - port1
\
port0
\
slaver1(eth1) - agg1.lag_ports -> NULL
\
port1
If we run 'ifenslave bond0 -d eth1', the process is like below:
excuting __bond_release_one()
|
bond_upper_dev_unlink()[step1]
| | |
| | bond_3ad_lacpdu_recv()
| | ->bond_3ad_rx_indication()
| | spin_lock_bh()
| | ->ad_rx_machine()
| | ->__record_pdu()[step2]
| | spin_unlock_bh()
| | |
| bond_3ad_state_machine_handler()
| spin_lock_bh()
| ->ad_port_selection_logic()
| ->try to find free aggregator[step3]
| ->try to find suitable aggregator[step4]
| ->did not find a suitable aggregator[step5]
| spin_unlock_bh()
| |
| |
bond_3ad_unbind_slave() |
spin_lock_bh()
spin_unlock_bh()
step1: already removed slaver1(eth1) from list, but port1 remains
step2: receive a lacpdu and update port0
step3: port0 will be removed from agg0.lag_ports. The struct is
"agg0.lag_ports -> port1" now, and agg0 is not free. At the
same time, slaver1/agg1 has been removed from the list by step1.
So we can't find a free aggregator now.
step4: can't find suitable aggregator because of step2
step5: cause a calltrace since port->aggregator is NULL
To solve this concurrency problem, put bond_upper_dev_unlink()
after bond_3ad_unbind_slave(). In this way, we can invalid the port
first and skip this port in bond_3ad_state_machine_handler(). This
eliminates the situation that the slaver has been removed from the
list but the port is still valid.

When running on an AMD vIOMMU, it is better to avoid TLB flushes
of unmodified PTEs. vIOMMUs require the hypervisor to synchronize the
virtualized IOMMU's PTEs with the physical ones. This process induce
overheads.
AMD IOMMU allows us to flush any range that is aligned to the power of
2. So when running on top of a vIOMMU, break the range into sub-ranges
that are naturally aligned, and flush each one separately. This apporach
is better when running with a vIOMMU, but on physical IOMMUs, the
penalty of IOTLB misses due to unnecessary flushed entries is likely to
be low.
Repurpose (i.e., keeping the name, changing the logic)
domain_flush_pages() so it is used to choose whether to perform one
flush of the whole range or multiple ones to avoid flushing unnecessary
ranges. Use NpCache, as usual, to infer whether the IOMMU is physical or
virtual.

AMD's IOMMU can flush efficiently (i.e., in a single flush) any range.
This is in contrast, for instnace, to Intel IOMMUs that have a limit on
the number of pages that can be flushed in a single flush. In addition,
AMD's IOMMU do not care about the page-size, so changes of the page size
do not need to trigger a TLB flush.
So in most cases, a TLB flush due to disjoint range is not needed for
AMD. Yet, vIOMMUs require the hypervisor to synchronize the virtualized
IOMMU's PTEs with the physical ones. This process induce overheads, so
it is better not to cause unnecessary flushes, i.e., flushes of PTEs
that were not modified.
Implement and use amd_iommu_iotlb_gather_add_page() and use it instead
of the generic iommu_iotlb_gather_add_page(). Ignore disjoint regions
unless "non-present cache" feature is reported by the IOMMU
capabilities, as this is an indication we are running on a physical
IOMMU. A similar indication is used by VT-d (see "caching mode"). The
new logic retains the same flushing behavior that we had before the
introduction of page-selective IOTLB flushes for AMD.
On virtualized environments, check if the newly flushed region and the
gathered one are disjoint and flush if it is.

Refactor iommu_iotlb_gather_add_page() and factor out the logic that
detects whether IOTLB gather range and a new range are disjoint. To be
used by the next patch that implements different gathering logic for
AMD.
Note that updating gather->pgsize unconditionally does not affect
correctness as the function had (and has) an invariant, in which
gather->pgsize always represents the flushing granularity of its range.
Arguably, “size" should never be zero, but lets assume for the matter of
discussion that it might.
If "size" equals to "gather->pgsize", then the assignment in question
has no impact.
Otherwise, if "size" is non-zero, then iommu_iotlb_sync() would
initialize the size and range (see iommu_iotlb_gather_init()), and the
invariant is kept.
Otherwise, "size" is zero, and "gather" already holds a range, so
gather->pgsize is non-zero and (gather->pgsize && gather->pgsize !=
size) is true. Therefore, again, iommu_iotlb_sync() would be called and
initialize the size.

TC action ->init() API has 10 parameters, it becomes harder
to read. Some of them are just boolean and can be replaced
by flags. Similarly for the internal API tcf_action_init()
and tcf_exts_validate().
This patch converts them to flags and fold them into
the upper 16 bits of "flags", whose lower 16 bits are still
reserved for user-space. More specifically, the following
kernel flags are introduced:
TCA_ACT_FLAGS_POLICE replace 'name' in a few contexts, to
distinguish whether it is compatible with policer.
TCA_ACT_FLAGS_BIND replaces 'bind', to indicate whether
this action is bound to a filter.
TCA_ACT_FLAGS_REPLACE replaces 'ovr' in most contexts,
means we are replacing an existing action.
TCA_ACT_FLAGS_NO_RTNL replaces 'rtnl_held' but has the
opposite meaning, because we still hold RTNL in most
cases.
The only user-space flag TCA_ACT_FLAGS_NO_PERCPU_STATS is
untouched and still stored as before.
I have tested this patch with tdc and I do not see any
failure related to this patch.

GSO expects inner transport header offset to be valid when
skb->encapsulation flag is set. GSO uses this value to calculate the length
of an individual segment of a GSO packet in skb_gso_transport_seglen().
However, tcp/udp gro_complete callbacks don't update the
skb->inner_transport_header when processing an encapsulated TCP/UDP
segment. As a result a GRO skb has ->inner_transport_header set to a value
carried over from earlier skb processing.
This can have mild to tragic consequences. From miscalculating the GSO
segment length to triggering a page fault [1], when trying to read TCP/UDP
header at an address past the skb->data page.
The latter scenario leads to an oops report like so:

The bug can be observed in a simple setup where we send IP/GRE/IP/TCP
packets into a netns over a veth pair. Inside the netns, packets are
forwarded to dummy device:
trafgen -> [veth A]--[veth B] -forward-> [dummy]
For veth B to GRO aggregate packets on receive, it needs to have an XDP
program attached (for example, a trivial XDP_PASS). Additionally, for UDP,
we need to enable GSO_UDP_L4 feature on the device:
ip netns exec A ethtool -K AB rx-udp-gro-forwarding on
The last component is an artificial delay to increase the chances of GRO
batching happening:
ip netns exec A tc qdisc add dev AB root \
netem delay 200us slot 5ms 10ms packets 2 bytes 64k
With such a setup in place, the bug can be observed by tracing the skb
outer and inner offsets when GSO skb is transmitted from the dummy device:
tcp:
FUNC DEV SKB_LEN NH TH ENC INH ITH GSO_SIZE GSO_TYPE
ip_finish_output dumB 2830 270 290 1 294 254 1383 (tcpv4,gre,)

^^^
Fix it by updating the inner transport header offset in tcp/udp
gro_complete callbacks, similar to how {inet,ipv6}_gro_complete callbacks
update the inner network header offset, when skb->encapsulation flag is
set.

provide the corresponding entries to the usb_audio_names[] table,
too.

The devices that can have media-controller API entries are currently
specified via tables in quirks-table.h, as a part of descriptor
override. This can fit better to the new quirk_flags, as we just need
a matching with the given ID and create the MC entries accordingly.

As more and more device-specific workarounds came up and gathered in
various places, it becomes harder to manage. Now it's time to clean
up and collect workarounds more consistently and make them more easily
applicable.
This patch is the first step for that: a new field quirk_flags is
introduced in snd_usb_audio struct to contain the bit flags for
various device-specific quirks. Those are separate one from the
quirks in quirks-table.h; the quirks-table.h entries are for more
intrusive stuff that needs the descriptor override, while the new
quirk_flags is for easier ones that are tied with the vendor:product
IDs.
In this patch, as the first example, we convert the list of devices
and vendors to ignore GET_SAMPLE_RATE, formerly defined in
snb_usb_get_sample_rate_quirk().

The recent code refactoring made the mmap of continuous pages to be
done via the own helper snd_dma_continuous_mmap() with
remap_pfn_range(). There I overlooked that dmab->addr isn't set for
the allocation with SNDRV_DMA_TYPE_CONTINUOUS. This resulted always
in an error at mmap with this buffer type on the system such as
Intel SST Baytrail driver.
This patch fixes the regression by passing the correct address.

Commit dea7a9fbb0 ("dmaengine: imx-dma: remove dma_slave_config
direction usage") changes the method from a "configuration when called"
to an "configuration when used". Due to this, only the cyclic DMA type
gets configured correctly, while the generic DMA type is left
non-configured.
Without this additional call, the struct imxdma_channel::word_size member
is stuck at DMA_SLAVE_BUSWIDTH_UNDEFINED and imxdma_prep_slave_sg() always
returns NULL.
