2007-07-10[BNX2]: Modify link up message.Michael Chan
Modify the link up dmesg to report remote copper or Serdes link. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[BNX2]: Add ethtool support for remote PHY.Michael Chan
Modify the driver's ethtool_ops->get_settings and set_settings functions to support remote PHY. Users control the remote copper PHY settings by specifying link settings for the tp (twisted pair) port. The nway_reset function is also modified to support remote PHY. mii-tool operations are not supported on remote PHY and we will return -EOPNOTSUPP.

2007-07-10[BNX2]: Add support for remote PHY.Michael Chan
In blade servers, the Serdes PHY in 5708S can control the remote copper PHY through autonegotiation on the backplane. This patch adds the logic to interface with the firmware to control the remote PHY autonegotiation and to handle remote PHY link events. When remote PHY is present, the 5708S Serdes device practically becomes a copper device with full control over the 1000Base-T link settings.

2007-07-10[BNX2]: Add remote PHY bit definitions.Michael Chan
Add new fields in struct bnx2 and other bit definitions in shared memory to support remote PHY. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[BNX2]: Add bnx2_set_default_link().Michael Chan
Put existing code to setup the default link settings in this new function. This makes it easier to support the remote PHY feature in the next few patches. Also change ETHTOOL_ALL_FIBRE_SPEED to include 2500Mbps if supported. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-07-10[NETFILTER]: nfnetlink_queue: don't unregister handler of other subsystemYasuyuki Kozakai
The queue handlers registered by ip[6]_queue.ko at initialization should not be unregistered according to requests from userland program using nfnetlink_queue. If we allow that, there is no way to register the handlers of built-in ip[6]_queue again.

2007-07-10[NETFILTER]: nf_conntrack: early_drop improvementPatrick McHardy
When the maximum number of conntrack entries is reached and a new one needs to be allocated, conntrack tries to drop an unassured connection from the same hash bucket the new conntrack would hash to. Since with a properly sized hash the average number of entries per bucket is 1, the chances of actually finding one are not very good. This patch makes it walk the hash until a minimum number of 8 entries are checked. Based on patch by Vasily Averin <vvs@sw.ru>.

2007-07-10[NETFILTER]: nf_conntrack_expect: introduce nf_conntrack_expect_max sysctPatrick McHardy
As a last step of preventing DoS by creating lots of expectations, this patch introduces a global maximum and a sysctl to control it. The default is initialized to 4 * the expectation hash table size, which results in 1/64 of the default maxmimum of conntracks. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[NETFILTER]: nf_conntrack_expect: maintain per conntrack expectation listPatrick McHardy
This patch brings back the per-conntrack expectation list that was removed around 2.6.10 to avoid walking all expectations on expectation eviction and conntrack destruction. As these were the last users of the global expectation list, this patch also kills that. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-07-10[NETFILTER]: nf_conntrack: use hashtable for expectationsPatrick McHardy
Currently all expectations are kept on a global list that - needs to be searched for every new conncetion - needs to be walked for evicting expectations when a master connection has reached its limit - needs to be walked on connection destruction for connections that have open expectations This is obviously not good, especially when considering helpers like H.323 that register *lots* of expectations and can set up permanent expectations, but it also allows for an easy DoS against firewalls using connection tracking helpers. Use a hashtable for expectations to avoid incurring the search overhead for every new connection. The default hash size is 1/256 of the conntrack hash table size, this can be overriden using a module parameter. This patch only introduces the hash table for expectation lookups and keeps other users to reduce the noise, the following patches will get rid of it completely.

2007-07-10[NETFILTER]: nf_conntrack_netlink: sync expectation dumping with conntrack ↵Patrick McHardy
table dumping Resync expectation table dumping code with conntrack dumping: don't rely on the unique ID anymore since that requires to walk the list backwards, which doesn't work with the upcoming conversion to hlists.

2007-07-10[NETFILTER]: nf_conntrack_expect: avoid useless list walkingPatrick McHardy
Don't walk the list when unexpecting an expectation, we already have a reference and the timer check is enough to guarantee that it still is on the list. This comment suggests that it was copied there by mistake from expectation eviction: /* choose the oldest expectation to evict */ Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[NETFILTER]: nf_conntrack: reduce masks to a subset of tuplesPatrick McHardy
Since conntrack currently allows to use masks for every bit of both helper and expectation tuples, we can't hash them and have to keep them on two global lists that are searched for every new connection. This patch removes the never used ability to use masks for the destination part of the expectation tuple and completely removes masks from helpers since the only reasonable choice is a full match on l3num, protonum and src.u.all.

2007-07-10[NETFILTER]: nf_conntrack: use hlists for conntrack hashPatrick McHardy
Convert conntrack hash to hlists to reduce its size and cache footprint. Since the default hashsize to max. entries ratio sucks (1:16), this patch doesn't reduce the amount of memory used for the hash by default, but instead uses a better ratio of 1:8, which results in the same max. entries value. One thing worth noting is early_drop. It really should use LRU, so it now has to iterate over the entire chain to find the last unconfirmed entry. Since chains shouldn't be very long and the entire operation is very rare this shouldn't be a problem. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-07-10[NETFILTER]: nf_conntrack: introduce extension infrastructureYasuyuki Kozakai
Old space allocator of conntrack had problems about extensibility. - It required slab cache per combination of extensions. - It expected what extensions would be assigned, but it was impossible to expect that completely, then we allocated bigger memory object than really required. - It needed to search helper twice due to lock issue. Now basic informations of a connection are stored in 'struct nf_conn'. And a storage for extension (helper, NAT) is allocated by kmalloc.
