The GENET driver supports SKB fragments, and succeeds in transmitting
them properly, but when reclaiming these transmitted fragments, we will
only update the count of free buffer descriptors by 1, even for SKBs
with fragments. This leads to the networking stack thinking it has more
room than the hardware has when pushing new SKBs, and backing off
consequently because we return NETDEV_TX_BUSY.
Fix this by accounting for the SKB nr_frags plus one (itself) and update
ring->free_bds accordingly with that value for each iteration loop in
__bcmgenet_tx_reclaim().

icsk_rto is a 32bit field, and icsk_backoff can reach 15 by default,
or more if some sysctl (eg tcp_retries2) are changed.
Better use 64bit to perform icsk_rto << icsk_backoff operations
As Joe Perches suggested, add a helper for this.

RFC2710 (MLDv1), section 3.7. says:
The length of a received MLD message is computed by taking the
IPv6 Payload Length value and subtracting the length of any IPv6
extension headers present between the IPv6 header and the MLD
message. If that length is greater than 24 octets, that indicates
that there are other fields present *beyond* the fields described
above, perhaps belonging to a *future backwards-compatible* version
of MLD. An implementation of the version of MLD specified in this
document *MUST NOT* send an MLD message longer than 24 octets and
MUST ignore anything past the first 24 octets of a received MLD
message.
RFC3810 (MLDv2), section 8.2.1. states for *listeners* regarding
presence of MLDv1 routers:
In order to be compatible with MLDv1 routers, MLDv2 hosts MUST
operate in version 1 compatibility mode. [...] When Host
Compatibility Mode is MLDv2, a host acts using the MLDv2 protocol
on that interface. When Host Compatibility Mode is MLDv1, a host
acts in MLDv1 compatibility mode, using *only* the MLDv1 protocol,
on that interface. [...]
While section 8.3.1. specifies *router* behaviour regarding presence
of MLDv1 routers:
MLDv2 routers may be placed on a network where there is at least
one MLDv1 router. The following requirements apply:
If an MLDv1 router is present on the link, the Querier MUST use
the *lowest* version of MLD present on the network. This must be
administratively assured. Routers that desire to be compatible
with MLDv1 MUST have a configuration option to act in MLDv1 mode;
if an MLDv1 router is present on the link, the system administrator
must explicitly configure all MLDv2 routers to act in MLDv1 mode.
When in MLDv1 mode, the Querier MUST send periodic General Queries
truncated at the Multicast Address field (i.e., 24 bytes long),
and SHOULD also warn about receiving an MLDv2 Query (such warnings
must be rate-limited). The Querier MUST also fill in the Maximum
Response Delay in the Maximum Response Code field, i.e., the
exponential algorithm described in section 5.1.3. is not used. [...]
That means that we should not get queries from different versions of
MLD. When there's a MLDv1 router present, MLDv2 enforces truncation
and MRC == MRD (both fields are overlapping within the 24 octet range).
Section 8.3.2. specifies behaviour in the presence of MLDv1 multicast
address *listeners*:
MLDv2 routers may be placed on a network where there are hosts
that have not yet been upgraded to MLDv2. In order to be compatible
with MLDv1 hosts, MLDv2 routers MUST operate in version 1 compatibility
mode. MLDv2 routers keep a compatibility mode per multicast address
record. The compatibility mode of a multicast address is determined
from the Multicast Address Compatibility Mode variable, which can be
in one of the two following states: MLDv1 or MLDv2.
The Multicast Address Compatibility Mode of a multicast address
record is set to MLDv1 whenever an MLDv1 Multicast Listener Report is
*received* for that multicast address. At the same time, the Older
Version Host Present timer for the multicast address is set to Older
Version Host Present Timeout seconds. The timer is re-set whenever a
new MLDv1 Report is received for that multicast address. If the Older
Version Host Present timer expires, the router switches back to
Multicast Address Compatibility Mode of MLDv2 for that multicast
address. [...]
That means, what can happen is the following scenario, that hosts can
act in MLDv1 compatibility mode when they previously have received an
MLDv1 query (or, simply operate in MLDv1 mode-only); and at the same
time, an MLDv2 router could start up and transmits MLDv2 startup query
messages while being unaware of the current operational mode.
Given RFC2710, section 3.7 we would need to answer to that with an MLDv1
listener report, so that the router according to RFC3810, section 8.3.2.
would receive that and internally switch to MLDv1 compatibility as well.
Right now, I believe since the initial implementation of MLDv2, Linux
hosts would just silently drop such MLDv2 queries instead of replying
with an MLDv1 listener report, which would prevent a MLDv2 router going
into fallback mode (until it receives other MLDv1 queries).
Since the mapping of MRC to MRD in exactly such cases can make use of
the exponential algorithm from 5.1.3, we cannot [strictly speaking] be
aware in MLDv1 of the encoding in MRC, it seems also not mentioned by
the RFC. Since encodings are the same up to 32767, assume in such a
situation this value as a hard upper limit we would clamp. We have asked
one of the RFC authors on that regard, and he mentioned that there seem
not to be any implementations that make use of that exponential algorithm
on startup messages. In any case, this patch fixes this MLD
interoperability issue.

Changes to the cls_u32 classifier must appear atomic to the
readers. Before this patch if a change is requested for both
the exts and ifindex, first the ifindex is updated then the
exts with tcf_exts_change(). This opens a small window where
a reader can have a exts chain with an incorrect ifindex. This
violates the the RCU semantics.
Here we resolve this by always passing u32_set_parms() a copy
of the tc_u_knode to work on and then inserting it into the hash
table after the updates have been successfully applied.
Tested with the following short script:
#tc filter add dev p3p2 parent 8001:0 protocol ip prio 99 handle 1: \

#tc filter add dev p3p2 parent 8001:0 protocol ip prio 99 \

Commit ce93718fb7cdbc064c3000ff59e4d3200bdfa744 ("net: Don't keep
around original SKB when we software segment GSO frames") frees the
original skb after software GSO even for dodgy gso skbs. This breaks
the stream throughput from untrusted sources, since only header
checking was done during software GSO instead of a true
segmentation. This patch fixes this by freeing the original gso skb
only when it was really segmented by software.

device Wake-on-LAN features and advertise those. Similarly, when
configuring Wake-on-LAN on a per-port network interface, we make sure
that we do not accept something the master network devices does not
support.
Finally, we need to maintain a bitmask of the ports enabled for

Since commit 412ca1550cbe ("macvlan: Move broadcasts into a work queue"), the
driver uses tx_queue_len of the master device as the limit of packets enqueuing.
Problem is that virtual drivers have this value set to 0, thus all broadcast
packets were rejected.
Because tx_queue_len was arbitrarily chosen, I replace it with a static limit
of 1000 (also arbitrarily chosen).

On 32-bit architectures, the legacy buffer_head functions are not always
handling the sector number with the proper 64-bit types, and will thus
fail on 4TB+ disks.
Any code that uses __getblk() (and thus bread(), breadahead(),
sb_bread(), sb_breadahead(), sb_getblk()), and calls it using a 64-bit
block on a 32-bit arch (where "long" is 32-bit) causes an inifinite loop
in __getblk_slow() with an infinite stream of errors logged to dmesg
like this:
__find_get_block_slow() failed. block=6740375944, b_blocknr=2445408648
b_state=0x00000020, b_size=512
device sda1 blocksize: 512
Note how in hex block is 0x191C1F988 and b_blocknr is 0x91C1F988 i.e. the
top 32-bits are missing (in this case the 0x1 at the top).
This is because grow_dev_page() is broken and has a 32-bit overflow due
to shifting the page index value (a pgoff_t - which is just 32 bits on
32-bit architectures) left-shifted as the block number. But the top
bits to get lost as the pgoff_t is not type cast to sector_t / 64-bit
before the shift.
This patch fixes this issue by type casting "index" to sector_t before
doing the left shift.
Note this is not a theoretical bug but has been seen in the field on a
4TiB hard drive with logical sector size 512 bytes.
This patch has been verified to fix the infinite loop problem on 3.17-rc5
kernel using a 4TB disk image mounted using "-o loop". Without this patch
doing a "find /nt" where /nt is an NTFS volume causes the inifinite loop
100% reproducibly whilst with the patch it works fine as expected.

Confirmed to fix at least the GK107 MBP.

Functions supplied in ip6_udp_tunnel.c are only needed when IPV6 is
selected. When IPV6 is not selected, those functions are stubbed out
in udp_tunnel.h.

This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?
