      mac80211_hwsim: treat as part of mac80211 for MAINTAINERS · 2af8c4dc
      由 Johannes Berg 提交于 
      Since I maintain this driver as part of mac80211, add it to
the file list for mac80211; this helps submitters send it to
me instead of Kalle and also makes the build robot apply the
patches for it on the right tree for build attempts.

      sctp: sctp_remaddr_seq_show use the wrong variable to dump transport info · 3d73e8fa
      由 Xin Long 提交于 
      Now in sctp_remaddr_seq_show(), we use variable *tsp to get the param *v.
but *tsp is also used to traversal transport_addr_list, which will cover
the previous value, and make sctp_transport_put work on the wrong transport.

So fix it by adding a new variable to get the param *v.

      sctp: lack the check for ports in sctp_v6_cmp_addr · 40b4f0fd
      由 Xin Long 提交于 
      As the member .cmp_addr of sctp_af_inet6, sctp_v6_cmp_addr should also check
the port of addresses, just like sctp_v4_cmp_addr, cause it's invoked by
sctp_cmp_addr_exact().

Now sctp_v6_cmp_addr just check the port when two addresses have different
family, and lack the port check for two ipv6 addresses. that will make
sctp_hash_cmp() cannot work well.

so fix it by adding ports comparison in sctp_v6_cmp_addr().

====================
phy: micrel: fix issues with interrupt on atmel boards

Since the phy is not polled anymore, there were issues getting a link on the
sama5d* xplained boards.

I'm not too sure about were those fixes should go and I'm wondering whether the
first one shoud be made generic.

For the second one, I found the PHY_HAS_MAGICANEG flag that is not used and I
wondering whether this is related to that kind of issue. I had a quick look at
the history and could'nt find its use.

      phy: micrel: Disable auto negotiation on startup · 99f81afc
      由 Alexandre Belloni 提交于 
      Disable auto negotiation on init to properly detect an already plugged
cable at boot.

At boot, when the phy is started, it is in the PHY_UP state.
However, if a cable is plugged at boot, because auto negociation is already
enabled at the time we get the first interrupt, the phy is already running.
But the state machine then switches from PHY_UP to PHY_AN and calls
phy_start_aneg(). phy_start_aneg() will not do anything because aneg is
already enabled on the phy. It will then wait for a interrupt before going
further. This interrupt will never happen unless the cable is unplugged and
then replugged.

It was working properly before 321beec5 (net: phy: Use interrupts when
available in NOLINK state) because switching to NOLINK meant starting
polling the phy, even if IRQ were enabled.

      At least on ksz8081, when getting back from power down, interrupts are
disabled. ensure they are reenabled if they were previously enabled.

This fixes resuming which is failing on the xplained boards from atmel

      ppp: lock ppp->flags in ppp_read() and ppp_poll() · edffc217
      由 Guillaume Nault 提交于 
      ppp_read() and ppp_poll() can be called concurrently with ppp_ioctl().
In this case, ppp_ioctl() might call ppp_ccp_closed(), which may update
ppp->flags while ppp_read() or ppp_poll() is reading it.
The update done by ppp_ccp_closed() isn't atomic due to the bit mask
operation ('ppp->flags &= ~(SC_CCP_OPEN | SC_CCP_UP)'), so concurrent
readers might get transient values.
Reading incorrect ppp->flags may disturb the 'ppp->flags & SC_LOOP_TRAFFIC'
test in ppp_read() and ppp_poll(), which in turn can lead to improper
decision on whether the PPP unit file is ready for reading or not.

Since ppp_ccp_closed() is protected by the Rx and Tx locks (with
ppp_lock()), taking the Rx lock is enough for ppp_read() and ppp_poll()
to guarantee that ppp_ccp_closed() won't update ppp->flags
concurrently.

The same reasoning applies to ppp->n_channels. The 'n_channels' field
can also be written to concurrently by ppp_ioctl() (through
ppp_connect_channel() or ppp_disconnect_channel()). These writes aren't
atomic (simple increment/decrement), but are protected by both the Rx
and Tx locks (like in the ppp->flags case). So holding the Rx lock
before reading ppp->n_channels also prevents concurrent writes.

      由 Ivan Vecera 提交于 
      Use list_move_tail() to move MAC address entry from list of pending
to list of active entries. Simple list_add_tail() leaves the entry
also in the first list, this leads to list corruption.
