This patch adds the GSO implementation for IPv4 TCP.
Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not
going to scale if we add any more segmentation methods (e.g., DCCP). So
let's merge them.They were used to tell the protocol of a packet. This function has been
subsumed by the new gso_type field. This is essentially a set of netdev
feature bits (shifted by 16 bits) that are required to process a specific
skb. As such it's easy to tell whether a given device can process a GSO
skb: you just have to and the gso_type field and the netdev's features
field.I've made gso_type a conjunction. The idea is that you have a base type
(e.g., SKB_GSO_TCPV4) that can be modified further to support new features.
For example, if we add a hardware TSO type that supports ECN, they would
declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would
have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO
packets would be SKB_GSO_TCPV4. This means that only the CWR packets need
to be emulated in software.Signed-off-by: Herbert Xu

Having two or more qdisc_run's contend against each other is bad because
it can induce packet reordering if the packets have to be requeued. It
appears that this is an unintended consequence of relinquinshing the queue
lock while transmitting. That in turn is needed for devices that spend a
lot of time in their transmit routine.There are no advantages to be had as devices with queues are inherently
single-threaded (the loopback device is not but then it doesn't have a
queue).Even if you were to add a queue to a parallel virtual device (e.g., bolt
a tbf filter in front of an ipip tunnel device), you would still want to
process the queue in sequence to ensure that the packets are ordered
correctly.The solution here is to steal a bit from net_device to prevent this.
BTW, as qdisc_restart is no longer used by anyone as a module inside the
kernel (IIRC it used to with netif_wake_queue), I have not exported the
new __qdisc_run function.Signed-off-by: Herbert Xu

Add a secmark field to IP and NF conntracks, so that security markings
on packets can be copied to their associated connections, and also
copied back to packets as required. This is similar to the network

enforcement of security policy rather than network policy.Signed-off-by: James Morris

Many of the TCP congestion methods all just use ssthresh
as the minimum congestion window on decrease. Rather than
duplicating the code, just have that be the default if that
handle in the ops structure is not set.Minor behaviour change to TCP compound. It probably wants
to use this (ssthresh) as lower bound, rather than ssthresh/2
because the latter causes undershoot on loss.Signed-off-by: Stephen Hemminger

This patch adds the structure xfrm_mode. It is meant to represent
the operations carried out by transport/tunnel modes.By doing this we allow additional encapsulation modes to be added
without clogging up the xfrm_input/xfrm_output paths.Candidate modes include 4-to-6 tunnel mode, 6-to-4 tunnel mode, and
BEET modes.Signed-off-by: Herbert Xu

The number of locks used to manage afinfo structures can easily be reduced
down to one each for policy and state respectively. This is based on the
observation that the write locks are only held by module insertion/removal
which are very rare events so there is no need to further differentiate
between the insertion of modules like ipv6 versus esp6.The removal of the read locks in xfrm4_policy.c/xfrm6_policy.c might look
suspicious at first. However, after you realise that nobody ever takes
the corresponding write lock you'll feel better :)As far as I can gather it's an attempt to guard against the removal of
the corresponding modules. Since neither module can be unloaded at all
we can leave it to whoever fixes up IPv6 unloading :)Signed-off-by: Herbert Xu

Attached are two small patches for include/net/ieee80211.h to prepare
for later submission of code to implement a user-space daemon that
supplies 802.11 regulatory information.The first change adds a bit indicating that 802.11h rules are to be
applied to a channel. As discussed earlier in this list, a single bit
is unlikely to be sufficient; however, at this time I have been unable
to find any regulations implementing differences between 802.11a and
802.11h other than DFS, radar detection and passive scanning. A single
bit is thus sufficient to convey to the driver that these rules should
be obeyed.The second change adds comments to the freq and max_power fields of
struct ieee80211_channel to indicate the units that are used.Signed-Off-By: Larry Finger

My router blew up earlier, but exhibited some interesting behaviour during
its dying moments. It was broadcasting beacons but wouldn't respond to
any authentication requests.I noticed that softmac wasn't playing nice with this, as I couldn't make it try
to connect to other networks after it had timed out authenticating to my ill
router.To resolve this, I modified the softmac event/notify API to pass the event
code to the callback, so that callbacks being notified from
IEEE80211SOFTMAC_EVENT_ANY masks can make some judgement. In this case, the
ieee80211softmac_assoc callback needs to make a decision based upon whether
the association passed or failed.Signed-off-by: Daniel Drake

This patch finishes of the partially-complete shared key authentication
implementation in softmac.The complication here is that we need to encrypt a management frame during
the authentication process. I don't think there are any other scenarios where
this would have to happen.To get around this without causing too many headaches, we decided to just use
software encryption for this frame. The softmac config option now selects
IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved
a modification to some otherwise unused ieee80211 API.Signed-off-by: Daniel Drake
