genetlink has a circular locking dependency when dumping the registered
families:
- dump start:
genl_rcv() : take genl_mutex
genl_rcv_msg() : call netlink_dump_start() while holding genl_mutex
netlink_dump_start(),
netlink_dump() : take nlk->cb_mutex
ctrl_dumpfamily() : try to detect this case and not take genl_mutex a
second time
- dump continuance:
netlink_rcv() : call netlink_dump
netlink_dump : take nlk->cb_mutex
ctrl_dumpfamily() : take genl_mutex
Register genl_lock as callback mutex with netlink to fix this. This slightly
widens an already existing module unload race, the genl ops used during the
dump might go away when the module is unloaded. Thomas Graf is working on a
seperate fix for this.

This reverts commit 608961a5ec.
The problem is that the mac80211 stack not only needs to be able to
muck with the link-level headers, it also might need to mangle all of
the packet data if doing sw wireless encryption.
This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the
bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for
bringing this bisection analysis to my attention), and Ilpo (for
trying to analyze this purely from the TCP side).
In 2.6.27 we can take another stab at this, by using something like
skb_cow_data() when the TX path of mac80211 ends up with a non-NULL
tx->key. The ESP protocol code in the IPSEC stack can be used as a
model for implementation.

The unix_dgram_sendmsg routine implements a (somewhat crude)
form of receiver-imposed flow control by comparing the length of the
receive queue of the 'peer socket' with the max_ack_backlog value
stored in the corresponding sock structure, either blocking
the thread which caused the send-routine to be called or returning
EAGAIN. This routine is used by both SOCK_DGRAM and SOCK_SEQPACKET
sockets. The poll-implementation for these socket types is
datagram_poll from core/datagram.c. A socket is deemed to be writeable
by this routine when the memory presently consumed by datagrams
owned by it is less than the configured socket send buffer size. This
is always wrong for connected PF_UNIX non-stream sockets when the
abovementioned receive queue is currently considered to be full.
'poll' will then return, indicating that the socket is writeable, but
a subsequent write result in EAGAIN, effectively causing an
(usual) application to 'poll for writeability by repeated send request
with O_NONBLOCK set' until it has consumed its time quantum.
The change below uses a suitably modified variant of the datagram_poll
routines for both type of PF_UNIX sockets, which tests if the
recv-queue of the peer a socket is connected to is presently
considered to be 'full' as part of the 'is this socket
writeable'-checking code. The socket being polled is additionally
put onto the peer_wait wait queue associated with its peer, because the
unix_dgram_sendmsg routine does a wake up on this queue after a
datagram was received and the 'other wakeup call' is done implicitly
as part of skb destruction, meaning, a process blocked in poll
because of a full peer receive queue could otherwise sleep forever
if no datagram owned by its socket was already sitting on this queue.
Among this change is a small (inline) helper routine named
'unix_recvq_full', which consolidates the actual testing code (in three
different places) into a single location.

The atl1 driver tries to determine the MAC address thusly:
- If an EEPROM exists, read the MAC address from EEPROM and
validate it.
- If an EEPROM doesn't exist, try to read a MAC address from
SPI flash.
- If that fails, try to read a MAC address directly from the
MAC Station Address register.
- If that fails, assign a random MAC address provided by the
kernel.
We now have a report of a system fitted with an EEPROM containing all
zeros where we expect the MAC address to be, and we currently handle
this as an error condition. Turns out, on this system the BIOS writes
a valid MAC address to the NIC's MAC Station Address register, but we
never try to read it because we return an error when we find the all-
zeros address in EEPROM.
This patch relaxes the error check and continues looking for a MAC
address even if it finds an illegal one in EEPROM.

Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.
This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

One way to fix this would be to split helper cleanup from the unregistration
function and invoke it for the H.245 helper, but since ctnetlink needs to be
able to find the helper for synchonization purposes, a better fix is to
register it normally and make sure its not assigned to connections during
helper lookup. The missing l3num initialization is enough for this, this
patch changes it to use AF_UNSPEC to make it more explicit though.

Selected device feature bits can be propagated to VLAN devices, so we
can make use of TX checksum offload and TSO on VLAN-tagged packets.
However, if the physical device does not do VLAN tag insertion or
generic checksum offload then the test for TX checksum offload in
dev_queue_xmit() will see a protocol of htons(ETH_P_8021Q) and yield
false.
This splits the checksum offload test into two functions:
- can_checksum_protocol() tests a given protocol against a feature bitmask
- dev_can_checksum() first tests the skb protocol against the device
features; if that fails and the protocol is htons(ETH_P_8021Q) then
it tests the encapsulated protocol against the effective device
features for VLANs

the check.

This fixes a possible NULL pointer dereference in an error path of the
DMA allocation error checking code. This is also necessary for a future
DMA API change that is on its way into the mainline kernel that adds
an additional dev parameter to dma_mapping_error().
This patch moves the whole struct b43_dmaring struct initialization
right before any DMA allocation operation.

None of the rt2x00 PCI devices support 64-bit DMA addresses (they all
only accept 32-bit buffer addresses). Hence it makes no sense to try to
enable 64-bit DMA addresses. Only try to enable 32-bit DMA addresses.

This fixes a "BUG: unable to handle kernel paging request"
bug in rt73usb which was caused by killing the guardian_urb
while it had never been allocated for rt73usb.
