bridge: multicast: restore perm router ports on multicast enable
Satish reported a problem with the perm multicast router ports not getting
reenabled after some series of events, in particular if it happens that the
multicast snooping has been disabled and the port goes to disabled state
then it will be deleted from the router port list, but if it moves into
non-disabled state it will not be re-added because the mcast snooping is
still disabled, and enabling snooping later does nothing.
Here are the steps to reproduce, setup br0 with snooping enabled and eth1
added as a perm router (multicast_router = 2):
1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping
2. $ ip l set eth1 down
^ This step deletes the interface from the router list
3. $ ip l set eth1 up
^ This step does not add it again because mcast snooping is disabled
4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping
5. $ bridge -d -s mdb show
<empty>
At this point we have mcast enabled and eth1 as a perm router (value = 2)
but it is not in the router list which is incorrect.
After this change:
1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping
2. $ ip l set eth1 down
^ This step deletes the interface from the router list
3. $ ip l set eth1 up
^ This step does not add it again because mcast snooping is disabled
4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping
5. $ bridge -d -s mdb show
router ports on br0: eth1
Note: we can directly do br_multicast_enable_port for all because the
querier timer already has checks for the port state and will simply
expire if it's in blocking/disabled. See the comment added by
commit

net: Require exact match for TCP socket lookups if dif is l3mdev
Currently, socket lookups for l3mdev (vrf) use cases can match a socket
that is bound to a port but not a device (ie., a global socket). If the
sysctl tcp_l3mdev_accept is not set this leads to ack packets going out
based on the main table even though the packet came in from an L3 domain.
The end result is that the connection does not establish creating
confusion for users since the service is running and a socket shows in
ss output. Fix by requiring an exact dif to sk_bound_dev_if match if the
skb came through an interface enslaved to an l3mdev device and the
tcp_l3mdev_accept is not set.
skb's through an l3mdev interface are marked by setting a flag in
inet{6}_skb_parm. The IPv6 variant is already set; this patch adds the
flag for IPv4. Using an skb flag avoids a device lookup on the dif. The
flag is set in the VRF driver using the IP{6}CB macros. For IPv4, the
inet_skb_parm struct is moved in the cb per commit
971f10eca186, so the
match function in the TCP stack needs to use TCP_SKB_CB. For IPv6, the
move is done after the socket lookup, so IP6CB is used.
The flags field in inet_skb_parm struct needs to be increased to add
another flag. There is currently a 1-byte hole following the flags,
so it can be expanded to u16 without increasing the size of the struct.

mac80211: move struct aead_req off the stack
Some crypto implementations (such as the generic CCM wrapper in crypto/)
use scatterlists to map fields of private data in their struct aead_req.
This means these data structures cannot live in the vmalloc area, which
means that they cannot live on the stack (with CONFIG_VMAP_STACK.)
This currently occurs only with the generic software implementation, but
the private data and usage is implementation specific, so move the whole
data structures off the stack into heap by allocating every time we need
to use them.
In addition, take care not to put any of our own stack allocations into
scatterlists. This involves reserving some extra room when allocating the
aead_request structures, and referring to those allocations in the scatter-
lists (while copying the data from the stack before the crypto operation)

net/mlx4_en: fixup xdp tx irq to match rx
In cases where the number of tx rings is not a multiple of the number of
rx rings, the tx completion event will be handled on a different core
from the transmit and population of the ring. Races on the ring will
lead to a double-free of the page, and possibly other corruption.
The rings are initialized by default with a valid multiple of rings,
based on the number of cpus, therefore an invalid configuration requires
ethtool to change the ring layout. For instance 'ethtool -L eth0 rx 9 tx
8' will cause packets received on rx0, and XDP_TX'd to tx48, to be
completed on cpu3 (48 % 9 == 3).
Resolve this discrepancy by shifting the irq for the xdp tx queues to
start again from 0, modulo rx_ring_num.

qed*: Fix Kconfig dependencies with INFINIBAND_QEDR
The qedr driver would require a tristate Kconfig option [to allow
it to compile as a module], and toward that end we've added the
INFINIBAND_QEDR option. But as we've made the compilation of the
qed/qede infrastructure required for RoCE dependent on the option
we'd be facing linking difficulties in case that QED=y or QEDE=y,
and INFINIBAND_QEDR=m.
To resolve this, we seperate between the INFINIBAND_QEDR option
and the infrastructure support in qed/qede by introducing a new
QED_RDMA option which would be selected by INFINIBAND_QEDR but would
be a boolean instead of a tristate; Following that, the qed/qede is
fixed based on this new option so that all config combinations would
be supported.

IPv6: fix DESYNC_FACTOR
The IPv6 temporary address generation uses a variable called DESYNC_FACTOR
to prevent hosts updating the addresses at the same time. Quoting RFC 4941:
... The value DESYNC_FACTOR is a random value (different for each
client) that ensures that clients don't synchronize with each other and
generate new addresses at exactly the same time ...
DESYNC_FACTOR is defined as:
DESYNC_FACTOR -- A random value within the range 0 - MAX_DESYNC_FACTOR.
It is computed once at system start (rather than each time it is used)
and must never be greater than (TEMP_VALID_LIFETIME - REGEN_ADVANCE).
First, I believe the RFC has a typo in it and meant to say: "and must
never be greater than (TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE)"
The reason is that at various places in the RFC, DESYNC_FACTOR is used in
a calculation like (TEMP_PREFERRED_LIFETIME - DESYNC_FACTOR) or
(TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE - DESYNC_FACTOR). It needs to be
smaller than (TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE) for the result of
these calculations to be larger than zero. It's never used in a
calculation together with TEMP_VALID_LIFETIME.
I already submitted an errata to the rfc-editor:
https://www.rfc-editor.org/errata_search.php?rfc=4941
The Linux implementation of DESYNC_FACTOR is very wrong:
max_desync_factor is used in places DESYNC_FACTOR should be used.
max_desync_factor is initialized to the RFC-recommended value for
MAX_DESYNC_FACTOR (600) but the whole point is to get a _random_ value.
And nothing ensures that the value used is not greater than
(TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE), which leads to underflows. The
effect can easily be observed when setting the temp_prefered_lft sysctl
e.g. to 60. The preferred lifetime of the temporary addresses will be
bogus.
TEMP_PREFERRED_LIFETIME and REGEN_ADVANCE are not constants and can be
influenced by these three sysctls: regen_max_retry, dad_transmits and
temp_prefered_lft. Thus, the upper bound for desync_factor needs to be
re-calculated each time a new address is generated and if desync_factor is
larger than the new upper bound, a new random value needs to be
re-generated.
And since we already have max_desync_factor configurable per interface, we
also need to calculate and store desync_factor per interface.

IB/ipoib: move back IB LL address into the hard header

In order to avoid GRO issue, on packet reception, the IPoIB driver
stash into the skb a dummy pseudo header, so that the received
packets have actually a hard header matching the declared length.
To avoid changing the connected mode maximum mtu, the allocated
head buffer size is increased by the pseudo header length.
After this commit, IPoIB performances are back to pre-regression
value.

ipv6: correctly add local routes when lo goes up
The goal of the patch is to fix this scenario:
ip link add dummy1 type dummy
ip link set dummy1 up
ip link set lo down ; ip link set lo up
After that sequence, the local route to the link layer address of dummy1 is
not there anymore.
When the loopback is set down, all local routes are deleted by
addrconf_ifdown()/rt6_ifdown(). At this time, the rt6_info entry still
exists, because the corresponding idev has a reference on it. After the rcu
grace period, dst_rcu_free() is called, and thus ___dst_free(), which will
set obsolete to DST_OBSOLETE_DEAD.
In this case, init_loopback() is called before dst_rcu_free(), thus
obsolete is still sets to something <= 0. So, the function doesn't add the
route again. To avoid that race, let's check the rt6 refcnt instead.

Pull XFS support for shared data extents from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle. This
pullreq contains the new shared data extents feature for XFS.
Given the complexity and size of this change I am expecting - like the
addition of reverse mapping last cycle - that there will be some
follow-up bug fixes and cleanups around the -rc3 stage for issues that
I'm sure will show up once the code hits a wider userbase.
What it is:
At the most basic level we are simply adding shared data extents to
XFS - i.e. a single extent on disk can now have multiple owners. To do
this we have to add new on-disk features to both track the shared
extents and the number of times they've been shared. This is done by
the new "refcount" btree that sits in every allocation group. When we
share or unshare an extent, this tree gets updated.
Along with this new tree, the reverse mapping tree needs to be updated
to track each owner or a shared extent. This also needs to be updated
ever share/unshare operation. These interactions at extent allocation
and freeing time have complex ordering and recovery constraints, so
there's a significant amount of new intent-based transaction code to
ensure that operations are performed atomically from both the runtime
and integrity/crash recovery perspectives.
We also need to break sharing when writes hit a shared extent - this
is where the new copy-on-write implementation comes in. We allocate
new storage and copy the original data along with the overwrite data
into the new location. We only do this for data as we don't share
metadata at all - each inode has it's own metadata that tracks the
shared data extents, the extents undergoing CoW and it's own private
extents.
Of course, being XFS, nothing is simple - we use delayed allocation
for CoW similar to how we use it for normal writes. ENOSPC is a
significant issue here - we build on the reservation code added in
4.8-rc1 with the reverse mapping feature to ensure we don't get
spurious ENOSPC issues part way through a CoW operation. These
mechanisms also help minimise fragmentation due to repeated CoW
operations. To further reduce fragmentation overhead, we've also
introduced a CoW extent size hint, which indicates how large a region
we should allocate when we execute a CoW operation.
With all this functionality in place, we can hook up .copy_file_range,
.clone_file_range and .dedupe_file_range and we gain all the
capabilities of reflink and other vfs provided functionality that
enable manipulation to shared extents. We also added a fallocate mode
that explicitly unshares a range of a file, which we implemented as an
explicit CoW of all the shared extents in a file.
As such, it's a huge chunk of new functionality with new on-disk
format features and internal infrastructure. It warns at mount time as
an experimental feature and that it may eat data (as we do with all
new on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time the kernel
with this code in it is released.
The new code causes 5-6 new failures with xfstests - these aren't
serious functional failures but things the output of tests changing
slightly due to perturbations in layouts, space usage, etc. OTOH,
we've added 150+ new tests to xfstests that specifically exercise this
new functionality so it's got far better test coverage than any
functionality we've previously added to XFS.
Darrick has done a pretty amazing job getting us to this stage, and
special mention also needs to go to Christoph (review, testing,
improvements and bug fixes) and Brian (caught several intricate bugs
during review) for the effort they've also put in.
Summary:
- unshare range (FALLOC_FL_UNSHARE) support for fallocate
- copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr
interface
- shared extent support for XFS
- copy-on-write support for shared extents
- copy_file_range support
- clone_file_range support (implements reflink)
- dedupe_file_range support

net: phy: Trigger state machine on state change and not polling.
The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.
If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.
If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.
Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.
This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,

xen-netback: fix guest Rx stall detection (after guest Rx refactor)
If a VIF has been ready for rx_stall_timeout (60s by default) and an
Rx ring is drained of all requests an Rx stall will be incorrectly
detected. When this occurs and the guest Rx queue is empty, the Rx
ring's event index will not be set and the frontend will not raise an
event when new requests are placed on the ring, permanently stalling
the VIF.
This is a regression introduced by
eb1723a29b9a7 (xen-netback:
refactor guest rx).
Fix this by reinstating the setting of queue->last_rx_time when
placing a packet onto the guest Rx ring.

Problem is that this is doing a BUILD_BUG_ON on a non-constant
expression because of trying to take offset of pas[i] in the
structure.
Fix is to create MLX5_ARRAY_SET64 that takes an additional argument
that is the field index to separate between BUILD_BUG_ON on the array
constant field and the indexed field to assign the value to.
There are two callers of MLX5_SET64 that are trying to get a variable
offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i'
as the arguments to use in the offset check and the indexed value
assignment.

qmi_wwan: add support for Quectel EC21 and EC25
The Quectel EC21 and EC25 need the same "set DTR" request as devices
based on the MDM9230 chipset, but has no USB3 support. Our best guess
is that the "set DTR" functionality depends on chipset and/or
baseband firmware generation. But USB3 is still an optional feature.
Since we cannot enable this unconditionally for all older devices, and
there doesn't appear to be anything we can use in the USB descriptors
to identify these chips, we are forced to use a device specific quirk

net_sched: do not broadcast RTM_GETTFILTER result
There are two ways to get tc filters from kernel to user space.
1) Full dump (tc_dump_tfilter())
2) RTM_GETTFILTER to get one precise filter, reducing overhead.
The second operation is unfortunately broadcasting its result,
polluting "tc monitor" users.
This patch makes sure only the requester gets the result, using
netlink_unicast() instead of rtnetlink_send()
Jamal cooked an iproute2 patch to implement "tc filter get" operation,
but other user space libraries already use RTM_GETTFILTER when a single
filter is queried, instead of dumping all filters.

ath10k: cache calibration data when the core is stopped
Commit
0b8e3c4ca29f ("ath10k: move cal data len to hw_params") broke retrieving
the calibration data from cal_data debugfs file. The length of file was always
zero. The reason is:
static ssize_t ath10k_debug_cal_data_read(struct file *file,
char __user *user_buf,
size_t count, loff_t *ppos)
{
struct ath10k *ar = file->private_data;
void *buf = file->private_data;
This is obviously bogus, private_data cannot contain both struct ath10k and the
buffer. Fix it by caching calibration data to ar->debug.cal_data. This also
allows it to be accessed when the device is not active (interface is down).
The cal_data buffer is fixed size because during the first firmware probe we
don't yet know what will be the lenght of the calibration data. It was simplest
just to use a fixed length. There's a WARN_ON() in
ath10k_debug_cal_data_fetch() if the buffer is too small.
Tested with qca988x and firmware 10.2.4.70.56.

rtlwifi: Fix regression caused by commit
d86e64768859
In commit
d86e64768859 ("rtlwifi: rtl818x: constify local structures"),
the configuration struct for most of the drivers was changed to be
constant. The problem is that five of the modified drivers need to be
able to update the firmware name based on the exact model of the card.
As the file names were stored in one of the members of that struct,
these drivers would fail with a kernel BUG splat when they tried to
update the firmware name.
Rather than reverting the previous commit, I used a suggestion by
Johannes Berg and made the firmware file name pointers be local to
the routines that update the software variables.
The configuration struct of rtl8192cu, which was not touched in the
previous patch, is now constantfied.
