* [NET]: DIV_ROUND_UP cleanup (part two)Ilpo Järvinen2007-10-1010-16/+21
| | | | | | | | | | | Hopefully captured all single statement cases under net/. I'm not too sure if there is some policy about #includes that are "guaranteed" (ie., in the current tree) to be available through some other #included header, so I just added linux/kernel.h to each changed file that didn't #include it previously.

* [IPV4] IPSEC: Omit redirect for tunnelled packet.Masahide NAKAMURA2007-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | IPv4 IPsec tunnel gateway incorrectly sends redirect to sender if it is onlink host when network device the IPsec tunnelled packet is arrived is the same as the one the decapsulated packet is sent. With this patch, it omits to send the redirect when the forwarding skbuff carries secpath, since such skbuff should be assumed as a decapsulated packet from IPsec tunnel by own. Request for comments: Alternatively we'd have another way to change net/ipv4/route.c (__mkroute_input) to use RTCF_DOREDIRECT flag unless skbuff has no secpath. It is better than this patch at performance point of view because IPv4 redirect judgement is done at routing slow-path. However, it should be taken care of resource changes between SAD(XFRM states) and routing table. In other words, When IPv4 SAD is changed does the related routing entry go to its slow-path? If not, it is reasonable to apply this patch. Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6] IPSEC: Omit redirect for tunnelled packet.Masahide NAKAMURA2007-10-101-1/+3
| | | | | | | | | | | | | | | | | | | IPv6 IPsec tunnel gateway incorrectly sends redirect to router or sender when network device the IPsec tunnelled packet is arrived is the same as the one the decapsulated packet is sent. With this patch, it omits to send the redirect when the forwarding skbuff carries secpath, since such skbuff should be assumed as a decapsulated packet from IPsec tunnel by own. It may be a rare case for an IPsec security gateway, however it is not rare when the gateway is MIPv6 Home Agent since the another tunnel end-point is Mobile Node and it changes the attached network.

* [IPV6] XFRM: Fix connected socket to use transformation.Noriaki TAKAMIYA2007-10-102-2/+41
| | | | | | | | | | | | | | | | | | | | When XFRM policy and state are ready after TCP connection is started, the traffic should be transformed immediately, however it does not on IPv6 TCP. It depends on a dst cache replacement policy with connected socket. It seems that the replacement is always done for IPv4, however, on IPv6 case it is done only when routing cookie is changed. This patch fix that non-transformation dst can be changed to transformation one. This behavior is required by MIPv6 and improves IPv6 IPsec. Fixes by Masahide NAKAMURA.

* [UDP]: Randomize port selection.Stephen Hemminger2007-10-103-42/+47
| | | | | | | | This patch causes UDP port allocation to be randomized like TCP. The earlier code would always choose same port (ie first empty list). Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [TCP] MIB: Add counters for discarded SACK blocksIlpo Järvinen2007-10-103-1/+15
| | | | | | | | | | | | | | In DSACK case, some events are not extraordinary, such as packet duplication generated DSACK. They can arrive easily below snd_una when undo_marker is not set (TCP being in CA_Open), counting such DSACKs amoung SACK discards will likely just mislead if they occur in some scenario when there are other problems as well. Similarly, excessively delayed packets could cause "normal" DSACKs. Therefore, separate counters are allocated for DSACK events.

* [TCP]: Discard fuzzy SACK blocksIlpo Järvinen2007-10-101-0/+82
| | | | | | | | | | | SACK processing code has been a sort of russian roulette as no validation of SACK blocks is previously attempted. Besides, it is not very clear what all kinds of broken SACK blocks really mean (e.g., one that has start and end sequence numbers reversed). So now close the roulette once and for all.

* [ATM]: Replace DPRINTK() with pr_debug().Stephen Hemminger2007-10-108-182/+120
| | | | | | | | | | | Get rid of using DPRINTK macro in ATM and use pr_debug (in kernel.h). Using the standard macro is cleaner and forces code to check for bad arguments and formatting.

* [NET] ethernet: optimize memcpy and memsetStephen Hemminger2007-10-101-8/+8
| | | | | | | | | | The ethernet header management only needs to handle a fixed size address (6 bytes). If the memcpy/memset are changed to be passed a constant length, then compiler can optimize for this case (and if it is smart eliminate string instructions).

* [XFRM] netlink: Establish an attribute policyThomas Graf2007-10-101-94/+31
| | | | | | | | | | Adds a policy defining the minimal payload lengths for all the attributes allowing for most attribute validation checks to be removed from in the middle of the code path.

* [XFRM] netlink: Use nlmsg_parse() to parse attributesThomas Graf2007-10-101-26/+12

* [DCCP]: Make ccid3_hc_tx_update_x get a timestamp if neededArnaldo Carvalho de Melo2007-10-101-14/+16
| | | | | | | | | | | | | The code was too complicated, if p > 0 in ccid3_hc_tx_no_feedback_timer the timestamp was being obtained to be passed to ccid3_hc_tx_update_x, where only if p > 0 the timestamp was needed, so just leave it to ccid3_hc_tx_update_x to obtain the timestamp if needed. This will help in the upcoming changesets where we'll convert t_ld to ktime_t. We'll eventually try to reuse ktime_get_real() calls again.
