This patch makes this function aware that the first frag and the header might
share the same ring slot. That could happen if the first slot is bigger than
PKT_PROT_LEN. Due to this the error path might release that slot twice or never,
depending on the error scenario.

When the grant operations failed, the skb is freed up eventually, and it tries
to release the frags, if there is any. For the main skb nr_frags is set to 0 to

to call put_page on the page pointer which contains garbage at that time.

To fix this - remove the limit of nestings when going through device tree,

and return them, instead of found/not found.

Packets originally buffered for the regular hardware tx queues can end

When packets are dropped due to retransmit failures, the pending frames
counter is not always updated properly.
Fix this by keeping track of the queue that a frame was accounted for in
the ath_frame_info struct, and using that on completion to decide
whether the counter should be updated.
This fixes some spurious transmit queue hangs.

Currently we might arrive to bond_net_exit() with some bonds left (that
were created while the module is unloading). We take care of that by
destroying sysfs (the last possibility to add new bonds) and then
destroying all the remaining bonds.
However, we destroy the /proc/net/bonding directory before destroying those
last bonds, and get a warning that we're trying to destroy a non-empty
proc directory (containing /proc/net/bonding/bondX).
Fix this by moving bond_destroy_proc_dir() after all the bonds are
destroyed, so that we're sure that no bonds exist.

Intel Wired LAN Driver Updates 2014-07-16
This series contains updates to i40e only.
Neerav adds support to get the port MAC address from firmware and adds
support to the ndo_get_phys_port_id() callback to provide port specific
unique ids to the netdev layer.
Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software
time stamp if the hardware time stamp is provided. Second fixes a race
condition on queueing skb for hardware time by using a simple bit lock to
avoid race conditions and leaking skbs when multiple transmit rings try
to claim time stamping.
Paul does some general cleanup of the driver to remove unneeded spaces,
comments that are no longer valid, and break that will never get touched.
Jacob Keller adds a verbose warning message when the incorrect PF attempts
to control timestamping for a port to which it was not assigned. The primary
intent of this message is to help debugging the reason why the SIOCSHWSTAMP
ioctl has failed and to help narrow the cause of the issue.

Commit 568f194e8b ("net: ppp: use
sk_unattached_filter api") inadvertently changed the logic when setting
PPP pass and active filters. This applies to both the generic PPP subsystem
implemented by drivers/net/ppp/ppp_generic.c and the ISDN PPP subsystem
implemented by drivers/isdn/i4l/isdn_ppp.c. The original code in ppp_ioctl()
(or isdn_ppp_ioctl(), resp.) handling PPPIOCSPASS and PPPIOCSACTIVE allowed to
remove a pass/active filter previously set by using a filter of length zero.
However, with the new code this is not possible anymore as this case is not
explicitly checked for, which leads to passing NULL as a filter to
sk_unattached_filter_create(). This results in returning EINVAL to the caller.
Additionally, the variables ppp->pass_filter and ppp->active_filter (or
is->pass_filter and is->active_filter, resp.) are not reset to NULL, although
the filters they point to may have been destroyed by
sk_unattached_filter_destroy(), so in this EINVAL case dangling pointers are
left behind (provided the pointers were previously non-NULL).
This patch corrects both problems by checking whether the filter passed is
empty or non-empty, and prevents sk_unattached_filter_create() from being
called in the first case. Moreover, the pointers are always reset to NULL
as soon as sk_unattached_filter_destroy() returns.

In TLB mode if tlb_dynamic_lb is NOT set, slaves from the bond
group are selected based on the hash distribution. This does not
exclude dead links which are part of the bond. Also if there is a
temporary link event which brings down the interface, packets
hashed on that interface would be dropped too.
This patch fixes these issues and distributes flows across the
UP links only. Also the array construction of links which are
capable of sending packets happen in the control path leaving
only link-selection during the data-path.
One possible side effect of this is - at a link event; all
flows will be shuffled to get good distribution. But impact of
this should be minimum with the assumption that a member or
members of the bond group are not available is a very temporary
situation.

Commit d762d03849 resets the counter holding the
next sequence number for multilink PPP fragments to zero whenever the
SC_MULTILINK flag is set. However, this counter only exists if
CONFIG_PPP_MULTILINK is defined. Consequently, the new code has to be enclosed
within #ifdef CONFIG_PPP_MULTILINK ... #endif.

Display a verbose warning message when the incorrect PF attempts to
control timestamping for a port to which it was not assigned. This
shouldn't display except in the case of multiple PFs per port. The
primary intent of this message is to help debugging the reason why the
SIOCSHWTSTAMP ioctl has failed, and to help narrow the cause of the
issue.

This patch adds a new API to get the port mac address from firmware.
It also adds support to the ndo_get_phys_port_id() callback to provide
port specific unique id to the netdev layer.
If the adapter has a valid per-port mac address then that
would be used for this purpose and is expected to be unique
on a per-port basis.
The information can be viewed by reading the phys_port_id
attribute in sysfs for each netdev or via IF netlink
interface.

Also, maintain current behaviour on the first slave (forcibly change fom to

This commit enhances the iwarp driver to optionally keep a log of rdma
work request timining data for kernel mode QPs. If iw_cxgb4 module option
c4iw_wr_log is set to non-zero, each work request is tracked and timing
data maintained in a rolling log that is 4096 entries deep by default.
Module option c4iw_wr_log_size_order allows specifing a log2 size to use
instead of the default order of 12 (4096 entries). Both module options
are read-only and must be passed in at module load time to set them. IE:
modprobe iw_cxgb4 c4iw_wr_log=1 c4iw_wr_log_size_order=10
The timing data is viewable via the iw_cxgb4 debugfs file "wr_log".
Writing anything to this file will clear all the timing data.
Data tracked includes:
- The host time when the work request was posted, just before ringing
the doorbell. The host time when the completion was polled by the
application. This is also the time the log entry is created. The delta
of these two times is the amount of time took processing the work request.
- The qid of the EQ used to post the work request.
- The work request opcode.
- The cqe wr_id field. For sq completions requests this is the swsqe
index. For recv completions this is the MSN of the ingress SEND.
This value can be used to match log entries from this log with firmware
flowc event entries.
- The sge timestamp value just before ringing the doorbell when
posting, the sge timestamp value just after polling the completion,
and CQE.timestamp field from the completion itself. With these three
timestamps we can track the latency from post to poll, and the amount
of time the completion resided in the CQ before being reaped by the
application. With debug firmware, the sge timestamp is also logged by
firmware in its flowc history so that we can compute the latency from
posting the work request until the firmware sees it.

Advertise a larger max read queue depth for qps, and gather the resource limits
from fw and use them to avoid exhaustinq all the resources.
Design:
cxgb4:
Obtain the max_ordird_qp and max_ird_adapter device params from FW
at init time and pass them up to the ULDs when they attach. If these
parameters are not available, due to older firmware, then hard-code
the values based on the known values for older firmware.
iw_cxgb4:
Fix the c4iw_query_device() to report these correct values based on
adapter parameters. ibv_query_device() will always return:
max_qp_rd_atom = max_qp_init_rd_atom = min(module_max, max_ordird_qp)
max_res_rd_atom = max_ird_adapter
Bump up the per qp max module option to 32, allowing it to be increased
by the user up to the device max of max_ordird_qp. 32 seems to be
sufficient to maximize throughput for streaming read benchmarks.
Fail connection setup if the negotiated IRD exhausts the available
adapter ird resources. So the driver will track the amount of ird
resource in use and not send an RI_WR/INIT to FW that would reduce the
available ird resources below zero.

Instead of waiting for IFF_UP of the primary net device to determine
the band and channel information of the wiphy structure, this is now
done during driver initialization in brcmf_cfg80211_attach(). The
channel information is obtained from the device and the 2G band is
updated when 40MHz bandwidth is enabled for that band. Before this
change the band and channel objects were common between multiple
brcmfmac devices in the system, which make that information rather
unreliable. That is also fixed with this reworked implementation.

Commit 568f194e8b ("net: ppp: use
sk_unattached_filter api") causes sk_chk_filter() to be called twice when
setting a PPP pass or active filter. This applies to both the generic PPP
subsystem implemented by drivers/net/ppp/ppp_generic.c and the ISDN PPP
subsystem implemented by drivers/isdn/i4l/isdn_ppp.c. The first call is from
within get_filter(). The second one is through the call chain
ppp_ioctl() or isdn_ppp_ioctl()
--> sk_unattached_filter_create()
--> __sk_prepare_filter()
--> sk_chk_filter()
The first call from within get_filter() should be deleted as get_filter() is
called just before calling sk_unattached_filter_create() later on, which
eventually calls sk_chk_filter() anyway.
For 3.15.x, this proposed change is a bugfix rather than a pure optimization as
in that branch, sk_chk_filter() may replace filter codes by other codes which
are not recognized when executing sk_chk_filter() a second time. So with
3.15.x, if sk_chk_filter() is called twice, the second invocation may yield
EINVAL (this depends on the filter codes found in the filter to be set, but
because the replacement is done for frequently used codes, this is almost
always the case). The net effect is that setting pass and/or active PPP filters
does not work anymore, since sk_unattached_filter_create() always returns
EINVAL due to the second call to sk_chk_filter(), regardless whether the filter
was originally sane or not.

The PPP channel MTU is used with Multilink PPP when ppp_mp_explode() (see
ppp_generic module) tries to determine how big a fragment might be. According
to RFC 1661, the MTU excludes the 2-byte PPP protocol field, see the
corresponding comment and code in ppp_mp_explode():
/*
* hdrlen includes the 2-byte PPP protocol field, but the
* MTU counts only the payload excluding the protocol field.
* (RFC1661 Section 2)
*/
mtu = pch->chan->mtu - (hdrlen - 2);
However, the pppoe module *does* include the PPP protocol field in the channel
MTU, which is wrong as it causes the PPP payload to be 1-2 bytes too big under
certain circumstances (one byte if PPP protocol compression is used, two
otherwise), causing the generated Ethernet packets to be dropped. So the pppoe
module has to subtract two bytes from the channel MTU. This error only
manifests itself when using Multilink PPP, as otherwise the channel MTU is not
used anywhere.
In the following, I will describe how to reproduce this bug. We configure two
pppd instances for multilink PPP over two PPPoE links, say eth2 and eth3, with
a MTU of 1492 bytes for each link and a MRRU of 2976 bytes. (This MRRU is
computed by adding the two link MTUs and subtracting the MP header twice, which
is 4 bytes long.) The necessary pppd statements on both sides are "multilink
mtu 1492 mru 1492 mrru 2976". On the client side, we additionally need "plugin
rp-pppoe.so eth2" and "plugin rp-pppoe.so eth3", respectively; on the server
side, we additionally need to start two pppoe-server instances to be able to
establish two PPPoE sessions, one over eth2 and one over eth3. We set the MTU
of the PPP network interface to the MRRU (2976) on both sides of the connection
in order to make use of the higher bandwidth. (If we didn't do that, IP
fragmentation would kick in, which we want to avoid.)
Now we send a ICMPv4 echo request with a payload of 2948 bytes from client to
server over the PPP link. This results in the following network packet:
2948 (echo payload)
+ 8 (ICMPv4 header)
+ 20 (IPv4 header)
---------------------
2976 (PPP payload)
These 2976 bytes do not exceed the MTU of the PPP network interface, so the
IP packet is not fragmented. Now the multilink PPP code in ppp_mp_explode()
prepends one protocol byte (0x21 for IPv4), making the packet one byte bigger
than the negotiated MRRU. So this packet would have to be divided in three
fragments. But this does not happen as each link MTU is assumed to be two bytes
larger. So this packet is diveded into two fragments only, one of size 1489 and
one of size 1488. Now we have for that bigger fragment:
1489 (PPP payload)
+ 4 (MP header)
+ 2 (PPP protocol field for the MP payload (0x3d))
+ 6 (PPPoE header)
--------------------------
1501 (Ethernet payload)
This packet exceeds the link MTU and is discarded.
If one configures the link MTU on the client side to 1501, one can see the
discarded Ethernet frames with tcpdump running on the client. A
ping -s 2948 -c 1 192.168.15.254
leads to the smaller fragment that is correctly received on the server side:
(tcpdump -vvvne -i eth3 pppoes and ppp proto 0x3d)
52:54:00:ad:87:fd > 52:54:00:79:5c:d0, ethertype PPPoE S (0x8864),
length 1514: PPPoE [ses 0x3] MLPPP (0x003d), length 1494: seq 0x000,
Flags [end], length 1492
and to the bigger fragment that is not received on the server side:
(tcpdump -vvvne -i eth2 pppoes and ppp proto 0x3d)
52:54:00:70:9e:89 > 52:54:00:5d:6f:b0, ethertype PPPoE S (0x8864),
length 1515: PPPoE [ses 0x5] MLPPP (0x003d), length 1495: seq 0x000,
Flags [begin], length 1493
With the patch below, we correctly obtain three fragments:
52:54:00:ad:87:fd > 52:54:00:79:5c:d0, ethertype PPPoE S (0x8864),
length 1514: PPPoE [ses 0x1] MLPPP (0x003d), length 1494: seq 0x000,
Flags [begin], length 1492
52:54:00:70:9e:89 > 52:54:00:5d:6f:b0, ethertype PPPoE S (0x8864),
length 1514: PPPoE [ses 0x1] MLPPP (0x003d), length 1494: seq 0x000,
Flags [none], length 1492
52:54:00:ad:87:fd > 52:54:00:79:5c:d0, ethertype PPPoE S (0x8864),
length 27: PPPoE [ses 0x1] MLPPP (0x003d), length 7: seq 0x000,
Flags [end], length 5
And the ICMPv4 echo request is successfully received at the server side:
IP (tos 0x0, ttl 64, id 21925, offset 0, flags [DF], proto ICMP (1),
length 2976)
192.168.222.2 > 192.168.15.254: ICMP echo request, id 30530, seq 0,
length 2956
The bug was introduced in commit c9aa689537
("[PPPOE]: Advertise PPPoE MTU") from the very beginning. This patch applies
to 3.10 upwards but the fix can be applied (with minor modifications) to
kernels as old as 2.6.32.

If firmware probing worker failed it called
device_release_driver() which synchronously called
remove() pci callback. The callback in turn waited
for the worker that called it to finish resulting
in a deadlock.
Waiting for a completion instead of a worker, like
some other drivers do, doesn't seem like the best
idea either:
Syscall Worker
probe_fw()
rmmod
dev_lock()
pci->remove()
wait_for_completion()
complete_all()
device_release_driver()
dev_lock()
[sleep]
free(ar)
dev_unlock()
[resume]
There's no guarantee that Worker upon resuming can
still access any data/code of the module.
Leaving device bound to a driver is not as harmful
as deadlocking so remove the call to
device_release_driver() while a proper solution is
figured out.
