* [DCCP]: Export dccp_insert_option_timestamp to CCIDsArnaldo Carvalho de Melo2005-08-302-4/+6
| | | | | | | | And don't insert a TIMESTAMP option in all packets, leave the decision to the CCIDs. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CCID]: Make ccid_hc_[rt]x_exit accept NULL argumentsArnaldo Carvalho de Melo2005-08-301-2/+4

* [DCCP]: Implement the CLOSING timerArnaldo Carvalho de Melo2005-08-304-31/+46
| | | | | | | | | | | So that we retransmit CLOSE/CLOSEREQ packets till they elicit an answer or we hit a timeout. Most of the machinery uses TCP approaches, this code has to be polished & audited, but this is better than we had before.

* [DCCP]: Fix the timestamp optionsIan McDonald2005-08-304-41/+79
| | | | | | | | | | | | | | | | This changes timestamp, timestamp echo, and elapsed time to use units of 10 usecs as per DCCP spec. This has been tested to verify that times are correct. Also fixed up length and used hton/ntoh more. Still to add in later patches: - actually use elapsed time to adjust RTT (commented out as was prior to this patch) - send options at times more closely following the spec (content is now correct) Signed-off-by: Ian McDonald <iam4@cs.waikato.ac.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

* [NET]: Implement SKB fast cloning.David S. Miller2005-08-304-16/+98
| | | | | | | | | | | | | | | | | Protocols that make extensive use of SKB cloning, for example TCP, eat at least 2 allocations per packet sent as a result. To cut the kmalloc() count in half, we implement a pre-allocation scheme wherein we allocate 2 sk_buff objects in advance, then use a simple reference count to free up the memory at the correct time. Based upon an initial patch by Thomas Graf and suggestions from Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | Using the group number allows increasing the number of groups without beeing limited by the size of the bitmask. It introduces one limitation for netlink users: messages can't be broadcasted to multiple groups anymore, however this feature was never used inside the kernel.

* [NETLINK]: Fix module refcounting problemsPatrick McHardy2005-08-301-65/+35Star
| | | | | | | | | | | | | | | | | Use-after-free: the struct proto_ops containing the module pointer is freed when a socket with pid=0 is released, which besides for kernel sockets is true for all unbound sockets. Module refcount leak: when the kernel socket is closed before all user sockets have been closed the proto_ops struct for this family is replaced by the generic one and the module refcount can't be dropped. The second problem can't be solved cleanly using module refcounting in the generic socket code, so this patch adds explicit refcounting to netlink_create/netlink_release.
