net: ethernet: xilinx_emaclite: set protocol selector bits when writing ANAR
This patch sets the protocol selector bits (4:0) of the PHY's MII_ADVERTISE
register (ANAR) when writing ADVERTISE_ALL. The protocol selector bits are
indicating IEEE 803.3u support and are fixed / read-only on some PHYs. Not
setting them correctly on others (like TI DP83630) makes the PHY fall back
to 10M HDX mode which should be avoided.
Tested for TI DP83630 PHY on Microblaze platform.

bnx2x: Fix bridged GSO for 57710/57711 chips
It was recently found out that GSO on 57710/57711 was broken, due to packets
being sent without a valid IP checksum.
Commit
057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this
issue, but failed to set the correct IP checksum when receiving GSO packets
via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed
to calculate IP checksum were erroneously set in the incorrect
buffer descriptor.
This patch re-enables GSO in said scenario for 57710/57711 chips.

This allows the kernel to probe the newly-exposed VFs before the PF is ready

Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

net/core: __hw_addr_sync_one / _multiple broken
Currently, __hw_addr_sync_one is called in a loop by
__hw_addr_sync_multiple to sync each of a "from" device's hw addresses
to a "to" device. __hw_addr_sync_one calls __hw_addr_add_ex to attempt
to add each address. __hw_addr_add_ex is called with global=false, and
sync=true.
__hw_addr_add_ex checks to see if the new address matches an
address already on the list. If so, it tests global and sync. In this
case, sync=true, and it then checks if the address is already synced,
and if so, returns 0.
This 0 return causes __hw_addr_sync_one to increment the sync_cnt
and refcount for the "from" list's address entry, even though the address
is already synced and has a reference and sync_cnt. This will cause
the sync_cnt and refcount to increment without bound every time an
addresses is added to the "from" device and synced to the "to" device.
The fix here has two parts:
First, when __hw_addr_add_ex finds the address already exists
and is synced, return -EEXIST instead of 0.
Second, __hw_addr_sync_one checks the error return for -EEXIST,
and if so, it (a) does not add a refcount/sync_cnt, and (b) returns 0
itself so that __hw_addr_sync_multiple will not return an error.

When performing the unsync operation (e.g., dev_mc_unsync),
__hw_addr_unsync_one calls __hw_addr_del_entry with the "synced"

released from the "from" list. This causes a test inside to fail,
with the result being that the reference count on the "from" address

* We now depend on the correct Kconfig symbol.
* We register an MEI event callback whenever we enable an NFC device,
otherwise we fail to read anything after an enable/disable cycle.
* We only disable an MEI device from its disable mey_phy_ops,
preventing useless consecutive disable calls.
- An NFC Makefile cleanup, as I forgot to remove a commented out line when

auth/assoc timeout changes, a fix from Felix for 64-bit traffic counters
and one from Helmut for address mask handling in mac80211. I also have a
few fixes myself for four different crashes reported by a few people."
And Johannes says this about the iwlwifi bit:
"This fixes a brown paper-bag bug that we really should've caught in
review. More details in the changelog for the fix."
On top of that...
Arend van Spriel and Hante Meuleman cooperate to send a series of AP

Gabor Juhos corrects a register offset for AR9550, avoiding a bus

Dan Carpenter provides a fixup to some dmesg output in the atmel

Subject: [PATCH 5/5] net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg
MSG_CMSG_COMPAT is (AFAIK) not intended to be part of the API --
it's a hack that steals a bit to indicate to other networking code
that a compat entry was used. So don't allow it from a non-compat
syscall.
This prevents an oops when running this code:
int main()
{
int s;
struct sockaddr_in addr;
struct msghdr *hdr;
char *highpage = mmap((void*)(TASK_SIZE_MAX - 4096), 4096,
PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS | MAP_FIXED, -1, 0);
if (highpage == MAP_FAILED)
err(1, "mmap");
s = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
if (s == -1)
err(1, "socket");
addr.sin_family = AF_INET;
addr.sin_port = htons(1);
addr.sin_addr.s_addr = htonl(INADDR_LOOPBACK);
if (connect(s, (struct sockaddr*)&addr, sizeof(addr)) != 0)
err(1, "connect");
void *evil = highpage + 4096 - COMPAT_MSGHDR_SIZE;
printf("Evil address is %p\n", evil);
if (syscall(__NR_sendmmsg, s, evil, 1, MSG_CMSG_COMPAT) < 0)

return 0;

mac80211: close AP_VLAN interfaces before unregistering all
Since Eric's commit
efe117ab8 ("Speedup ieee80211_remove_interfaces")
there's a bug in mac80211 when it unregisters with AP_VLAN interfaces
up. If the AP_VLAN interface was registered after the AP it belongs
to (which is the typical case) and then we get into this code path,
unregister_netdevice_many() will crash because it isn't prepared to
deal with interfaces being closed in the middle of it. Exactly this
happens though, because we iterate the list, find the AP master this
AP_VLAN belongs to and dev_close() the dependent VLANs. After this,
unregister_netdevice_many() won't pick up the fact that the AP_VLAN
is already down and will do it again, causing a crash.

A lot of code in mac80211 assumes that the hw queues are

copying the AP master configuration when an AP VLAN is
brought up, after this the AP interface can't change its
configuration any more and needs to be brought down to
change it, which also forces AP_VLAN interfaces down, so
just copying in open() is sufficient.

GFS2: Use single-block reservations for directories
This patch changes the multi-block allocation code, such that
directory inodes only get a single block reserved in the bitmap.
That way, the bitmaps are more tightly packed together, and there
are fewer spans of free blocks for in-use block reservations.
This means it takes less time to find a free span of blocks in the
bitmap, which speeds things up. This increases the performance of
some workloads by almost 2X. In Nate's mockup.py script (which does
(1) create dir, (2) create dir in dir, (3) create file in that dir)
the test executes in 23 steps rather than 43 steps, a 47%
performance improvement.

Recent commit
e61133dda480062d221f09e4fc18f66763f8ecd0 added support
for a new firmware feature to force an adapter to use 32 bit MSIs.
However, this firmware is not available for all systems. The hack below
allows devices needing 32 bit MSIs to work on these systems as well.
It is careful to only enable this on Gen2 slots, which should limit
this to configurations where this hack is needed and tested to work.

The code may return an invalide descriptor, when there is no nic descriptor

even there is no nic descriptor, it will still return the lase descriptor

mac80211: fix queue handling crash
The code I added in "mac80211: don't start new netdev queues

because while they have a netdev, they don't have queues set
up by the driver.
To fix the crash, exclude these from queue accounting here
and just start their netdev queues unconditionally.
For monitor, this is the best we can do, as we can redirect
frames there to any other interface and don't know which one
that will since it can be different for each frame.
For AP VLAN interfaces, we can do better later and actually
properly track the queue status. Not doing this is really a
separate bug though.

terminated strings to user-space since the maximum length of the
prefix that is passed by nf_log is NF_LOG_PREFIXLEN but pm->prefix
is 32 bytes long (ULOG_PREFIX_LEN).
This is actually happening already from nf_conntrack_tcp if ipt_ULOG
is used, since it is passing strings longer than 32 bytes.

netfilter: add nf_ipv6_ops hook to fix xt_addrtype with IPv6
Quoting https://bugzilla.netfilter.org/show_bug.cgi?id=812:
[ ip6tables -m addrtype ]
When I tried to use in the nat/PREROUTING it messes up the
routing cache even if the rule didn't matched at all.
[..]
If I remove the --limit-iface-in from the non-working scenario, so just
use the -m addrtype --dst-type LOCAL it works!
This happens when LOCAL type matching is requested with --limit-iface-in,
and the default ipv6 route is via the interface the packet we test
arrived on.
Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation
creates an unwanted cached entry, and the packet won't make it to the
real/expected destination.
Silently ignoring --limit-iface-in makes the routing work but it breaks
rule matching (--dst-type LOCAL with limit-iface-in is supposed to only
match if the dst address is configured on the incoming interface;
without --limit-iface-in it will match if the address is reachable
via lo).
The test should call ipv6_chk_addr() instead. However, this would add
a link-time dependency on ipv6.
There are two possible solutions:
1) Revert the commit that moved ipt_addrtype to xt_addrtype,
and put ipv6 specific code into ip6t_addrtype.
2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions.
While the former might seem preferable, Pablo pointed out that there
are more xt modules with link-time dependeny issues regarding ipv6,
so lets go for 2).

virtio_net: enable napi for all possible queues during open
Commit
55257d72bd1c51f25106350f4983ec19f62ed1fa (virtio-net: fill only rx
queues which are being used) only does the napi enabling during open for
curr_queue_pairs. This will break multiqueue receiving since napi of new queues
were still disabled after changing the number of queues.
This patch fixes this by enabling napi for all possible queues during open.

tcp: bug fix in proportional rate reduction.
This patch is a fix for a bug triggering newly_acked_sacked < 0
in tcp_ack(.).
The bug is triggered by sacked_out decreasing relative to prior_sacked,
but packets_out remaining the same as pior_packets. This is because the
snapshot of prior_packets is taken after tcp_sacktag_write_queue() while
prior_sacked is captured before tcp_sacktag_write_queue(). The problem
is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment)
adjusts the pcount for packets_out and sacked_out (MSS change or other
reason). As a result, this delta in pcount is reflected in
(prior_sacked - sacked_out) but not in (prior_packets - packets_out).
This patch does the following:
1) initializes prior_packets at the start of tcp_ack() so as to
capture the delta in packets_out created by tcp_fragment.
2) introduces a new "previous_packets_out" variable that snapshots
packets_out right before tcp_clean_rtx_queue, so pkts_acked can be
correctly computed as before.
3) Computes pkts_acked using previous_packets_out, and computes
newly_acked_sacked using prior_packets.
