Some of our FDDI support code has been apparently written with an
assumption that tabs are 4-character wide. In preparation to the next
change this update reformats <linux/if_fddi.h> so that it stays within 79
columns and otherwise renders correctly with 8-character tabs. No
functional change.

The commit a8b9b96e95 ("tipc: fix race
in disc create/delete") leads to the following static checker warning:
net/tipc/discover.c:352 tipc_disc_create()
warn: possible memory leak of 'req'
The risk of memory leak really exists in practice. Especially when
it's failed to allocate memory for "req->buf", tipc_disc_create()
doesn't free its allocated memory, instead just directly returns
with ENOMEM error code. In this situation, memory leak, of course,
happens.

tipc: add support for link state subscriptions
Low level topology information like TIPC link up/down is useful for
applications like teamd to make smarter failover decisions in a
HA cluster environment. Fetching logical link names through an ioctl
may hurt the eyes of some. Suggestions for a more elegant way of doing
this would be appreciated in that case. :)
v2:
-Properly based on net-next
-Off-list comments from Billie Alsup:
-Add a string length parameter to tipc_node_get_linkname
-Use TIPC_MAX_LINK_NAME definition instead of hardcoded
value in tipc_sioc_ln_req linkname
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
We add a new ioctl for AF_TIPC that can be used to fetch the
logical name for a link to a remote node on a given bearer. This
should be used in combination with link state subscriptions.
The logical name size limit definitions are moved to tipc.h, as
they are now also needed by the new ioctl.

Current code checks if the 20MHz bandwidth is allowed for
particular channel -- if it is not, the channel is disabled.
Since we need to use 5/10 MHz channels, this code is modified in
the way that the default bandwidth to check is 5MHz. If the
maximum bandwidth allowed by the channel is smaller than 5MHz,
the channel is disabled. Otherwise the channel is used and the
flags are set according to the bandwidth allowed by the channel.

Since there are frequency bands (e.g. 5.9GHz) allowing channels
with only 10 or 5 MHz bandwidth, this patch adds attributes that
allow keeping track about this information.
When channel attributes are reported to user-space, make sure to
not break old tools, i.e. if the 'split wiphy dump' is enabled,
report the extra attributes (if present) describing the bandwidth
restrictions. If the 'split wiphy dump' is not enabled,
completely omit those channels that have flags set to either
IEEE80211_CHAN_NO_10MHZ or IEEE80211_CHAN_NO_20MHZ.
Add the check for new bandwidth restriction flags in
cfg80211_chandef_usable() to comply with the restrictions.

Channel context refcount is protected by

Theoretically ieee80211_channel_switch() could

of, e.g. "2". This means mac80211 could accept CSA

This allows new vifs to be assigned to a chanctx
as long as chanctx's reservation chandefs (if any)
and chanctx's current chandef (implied by assigned

This implies it is impossible to assign a new vif
