Enhance sched scan to support option of finding a better BSS while in
connected state. Firmware scans the medium and reports when it finds a
known BSS which has better RSSI than the current connected BSS. New
attributes to specify the relative RSSI (compared to the current BSS)
are added to the sched scan to implement this.

Add support to use a random local address (Address 2 = TA in transmit
and the same address in receive functionality) for Public Action frames
in order to improve privacy of WLAN clients. Applications fill the
random transmit address in the frame buffer in the NL80211_CMD_FRAME
command. This can be used only with the drivers that indicate support
for random local address by setting the new
NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or
NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features.
The driver needs to configure receive behavior to accept frames to the
specified random address during the time the frame exchange is pending
and such frames need to be acknowledged similarly to frames sent to the
local permanent address when this random address functionality is not
used.

With 78, 111 and 85 bytes respectively (on x86-64), the
functions iwe_stream_add_event(), iwe_stream_add_point()
and iwe_stream_add_value() really shouldn't be inlines.
It appears that at least my compiler already decided
the same, and created a single instance of each one
of them for each file using it, but that's still a
number of instances in the system overall, which this
reduces.

Recently we started using ipmr with thousands of entries and easily hit
soft lockups on smaller devices. The reason is that the hash function
uses the high order bits from the src and dst, but those don't change in
many common cases, also the hash table is only 64 elements so with
thousands it doesn't scale at all.
This patch migrates the hash table to rhashtable, and in particular the
rhl interface which allows for duplicate elements to be chained because
of the MFC_PROXY support (*,G; *,*,oif cases) which allows for multiple
duplicate entries to be added with different interfaces (IMO wrong, but
it's been in for a long time).
And here are some results from tests I've run in a VM:
mr_table size (default, allocated for all namespaces):
Before After
49304 bytes 2400 bytes
Add 65000 routes (the diff is much larger on smaller devices):
Before After
1m42s 58s
Forwarding 256 byte packets with 65000 routes (test done in a VM):
Before After
3 Mbps / ~1465 pps 122 Mbps / ~59000 pps
As a bonus we no longer see the soft lockups on smaller devices which
showed up even with 2000 entries before.

In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path
invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes
svc_rdma_put_frmr() which in turn tries to unmap the same sg list through
ib_dma_unmap_sg() again. This second unmap is invalid and could lead to
problems when the iova being unmapped is subsequently reused. Remove
the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr()
handle it.

Context expiry times are in units of seconds since boot, not unix time.
The use of get_seconds() here therefore sets the expiry time decades in
the future. This prevents timely freeing of contexts destroyed by
client RPC_GSS_PROC_DESTROY requests. We'd still free them eventually
(when the module is unloaded or the container shut down), but a lot of

When structs are used to store temporary state in cb[] buffer that is
used with programs and among tail calls, then the generated code will
not always access the buffer in bpf_w chunks. We can ease programming
of it and let this act more natural by allowing for aligned b/h/w/dw
sized access for cb[] ctx member. Various test cases are attached as
well for the selftest suite. Potentially, this can also be reused for
other program types to pass data around.

Currently, when calling convert_ctx_access() callback for the various
program types, we pass in insn->dst_reg, insn->src_reg, insn->off from
the original instruction. This information is needed to rewrite the
instruction that is based on the user ctx structure into a kernel
representation for the ctx. As we'd like to allow access size beyond
just BPF_W, we'd need also insn->code for that in order to decode the
original access size. Given that, lets just pass insn directly to the
convert_ctx_access() callback and work on that to not clutter the
callback with even more arguments we need to pass when everything is
already contained in insn. So lets go through that once, no functional
change.

When an associated station changes its VHT operating mode this
can/will affect the bandwidth it's using, and consequently we
must recalculate the minimum bandwidth we need to use. Failure
to do so can lead to one of two scenarios:
1) we use a too high bandwidth, this is benign
2) we use a too narrow bandwidth, causing rate control and
actual PHY configuration to be out of sync, which can in
turn cause problems/crashes
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
|
|
In the current minimum chandef code there's an issue in that the
recalculation can happen after rate control is initialized for a
station that has a wider bandwidth than the current chanctx, and
then rate control can immediately start using those higher rates
which could cause problems.
Observe that first of all that this problem is because we don't
take non-associated and non-uploaded stations into account. The
restriction to non-associated is quite pointless and is one of
the causes for the problem described above, since the rate init
will happen before the station is set to associated; no frames
could actually be sent until associated, but the rate table can
already contain higher rates and that might cause problems.
Also, rejecting non-uploaded stations is wrong, since the rate
control can select higher rates for those as well.
Secondly, it's then necessary to recalculate the minimal config
before initializing rate control, so that when rate control is
initialized, the higher rates are already available. This can be
done easily by adding the necessary function call in rate init.

Currently, this attribute is only fetched on station addition, but
not on station change. Since this info is only present in the assoc
request, with full station state support in the driver it cannot be
present when the station is added.
Thus, add support for changing the VHT opmode on station update if
done before (or while) the station is marked as associated. After
this, ignore it, since it used to be ignored.

In the new DTS bindings for DSA (dsa2), the "ethernet" and "link"
phandles are respectively mandatory and exclusive to CPU port and DSA
link device tree nodes.
Simplify dsa2.c a bit by checking the presence of such phandle instead
of checking the redundant "label" property.
Then the Linux philosophy for Ethernet switch ports is to expose them to
userspace as standard NICs by default. Thus use the standard enumerated
"eth%d" device name if no "label" property is provided for a user port.
This allows to save DTS files from subjective net device names.
If one wants to rename an interface, udev rules can be used as usual.
Of course the current behavior is unchanged, and the optional "label"
property for user ports has precedence over the enumerated name.

There is not a valid reason to attempt setting the monitor channel
while in managed mode. Since this code path only deals with this mode,
remove the code block.
Johannes: I'll note that the comment indicated it was for backward
compatibility, but the code wasn't functional since switching the
monitor channel isn't supported (any more?) when in managed mode, as
that mode owns the channel configuration. Additionally, since monitor
can't be done on a managed mode interface, this would only have had
any effect to start with if a separate monitor interface is present,
in which case it's better to change the channel through that anyway,
if even possible.

page_frag_free
Patch series "Page fragment updates", v4.
This patch series takes care of a few cleanups for the page fragments
API.
First we do some renames so that things are much more consistent. First
we move the page_frag_ portion of the name to the front of the functions
names. Secondly we split out the cache specific functions from the
other page fragment functions by adding the word "cache" to the name.
Finally I added a bit of documentation that will hopefully help to
explain some of this. I plan to revisit this later as we get things
more ironed out in the near future with the changes planned for the DMA
setup to support eXpress Data Path.
This patch (of 3):
This patch renames the page frag functions to be more consistent with
other APIs. Specifically we place the name page_frag first in the name
and then have either an alloc or free call name that we append as the
suffix. This makes it a bit clearer in terms of naming.
In addition we drop the leading double underscores since we are
technically no longer a backing interface and instead the front end that
is called from the networking APIs.

The GRO fast path caches the frag0 address. This address becomes
invalid if frag0 is modified by pskb_may_pull or its variants.
So whenever that happens we must disable the frag0 optimization.
This is usually done through the combination of gro_header_hard
and gro_header_slow, however, the IPv6 extension header path did
the pulling directly and would continue to use the GRO fast path
incorrectly.
This patch fixes it by disabling the fast path when we enter the
IPv6 extension header path.

The GRO path has a fast-path where we avoid calling pskb_may_pull
and pskb_expand by directly accessing frag0. However, this should
only be done if we have enough tailroom in the skb as otherwise
we'll have to expand it later anyway.
This patch adds the check by capping frag0_len with the skb tailroom.

With commit e53743994e21
("af_iucv: use paged SKBs for big outbound messages"),
we transmit paged skbs for both of AF_IUCV's transport modes
(IUCV or HiperSockets).
The qeth driver for Layer 3 HiperSockets currently doesn't
support NETIF_F_SG, so these skbs would just be linearized again
by the stack.
Avoid that overhead by using paged skbs only for IUCV transport.
cc stable, since this also circumvents a significant skb leak when
sending large messages (where the skb then needs to be linearized).

It is perfectly possible to have non zero indexed switches being present
in a DSA switch tree, in such a case, we will be deferencing a NULL
pointer while dsa_cpu_port_ethtool_{setup,restore}. Be more defensive
and ensure that dst->ds[0] is valid before doing anything with it.

Make sockfs_setattr() static as it is not used outside of net/socket.c
This fixes the following GCC warning:
net/socket.c:534:5: warning: no previous prototype for ‘sockfs_setattr’ [-Wmissing-prototypes]

Instead of:
if (foo) {
unlock();
return bar();
}
unlock();
do:
unlock();
if (foo)
return bar();
This is ok because rcu protected structure is only dereferenced before
the conditional.

xfrm_init_tempstate is always called from within rcu read side section.
We can thus use a simpler function that doesn't call rcu_read_lock
again.
While at it, also make xfrm_init_tempstate return value void, the
return value was never tested.
A followup patch will replace remaining callers of xfrm_state_get_afinfo
with xfrm_state_afinfo_get_rcu variant and then remove the 'old'
get_afinfo interface.

commit 44abdc3047aecafc141dfbaf1ed
("xfrm: replace rwlock on xfrm_state_afinfo with rcu") made
xfrm_state_put_afinfo equivalent to rcu_read_unlock.
Use spatch to replace it with direct calls to rcu_read_unlock:

struct xfrm_state_afinfo *a;
