On most systems most of the TCP established/time-wait hash buckets are empty. When walking the hash table for /proc/net/tcp their read locks would always be aquired just to find out they're empty. This patch changes the code to check first if the buckets have any entries before taking the lock, which is much cheaper than taking a lock. Since the hash tables are large this makes a measurable difference on processing /proc/net/tcp, especially on architectures with slow read_lock (e.g. PPC) On a 2GB Core2 system time cat /proc/net/tcp > /dev/null (with a mostly empty hash table) goes from 0.046s to 0.005s. On systems with slower atomics (like P4 or POWER4) or larger hash tables (more RAM) the difference is much higher. This can be noticeable because there are some daemons around who regularly scan /proc/net/tcp. Original idea for this patch from Marcus Meissner, but redone by me.

The BUG_ON(w_tot == 0) only holds if there is no more than 1 loss interval in the loss history. If there is only a single loss interval, the calc_i_mean() routine need in fact not be called (RFC 3448, 6.3.1). Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>

This sets the sysfs permissions so that root can toggle the `debug' parameter available for nearly every DCCP module. This is useful since there are various module inter-dependencies. The debug flag can now be toggled at runtime using echo 1 > /sys/module/dccp/parameters/dccp_debug echo 1 > /sys/module/dccp_ccid2/parameters/ccid2_debug echo 1 > /sys/module/dccp_ccid3/parameters/ccid3_debug echo 1 > /sys/module/dccp_tfrc_lib/parameters/tfrc_debug The last is not very useful yet, since no code at the moment calls the tfrc_debug() macro.

dccp_disconnect() can be called due to several reasons: 1. when the connection setup failed (inet_stream_connect()); 2. when shutting down (inet_shutdown(), inet_csk_listen_stop()); 3. when aborting the connection (dccp_close() with 0 linger time). In case (1) the write queue is empty. This patch empties the write queue, if in case (2) or (3) it was not yet empty. This avoids triggering the write-queue BUG_TRAP in sk_stream_kill_queues() later on. It also seems natural to do: when breaking an association, to delete all packets that were originally intended for the soon-disconnected end (compare with call to tcp_write_queue_purge in tcp_disconnect()).

This updates the use of the `out_invalid_option' label, which produces a Reset (code 5, "Option Error"), to fill in the Data1...Data3 fields as specified in RFC 4340, 5.6. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>

This updates the option-parsing code with regard to RFC 4340, 5.8: "[..] options with nonsensical lengths (length byte less than two or more than the remaining space in the options portion of the header) MUST be ignored, and any option space following an option with nonsensical length MUST likewise be ignored." Hence in the following cases erratic options will be ignored: 1. The type byte of a multi-byte option is the last byte of the header options (i.e. effective option length of 1). 2. The value of the length byte is less than the minimum 2. This has been changed from previously 3: although no multi-byte option with a length less than 3 yet exists (cf. table 3 in 5.8), a length of 2 is valid. (The switch-statement in dccp_parse has further per-option length checks.) 3. The option length exceeds the length of the remaining option space. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>

RFC4340 states that if a packet is received with an option error (such as a Mandatory Option as the last byte of the option list), the endpoint should repond with a Reset. In the LISTEN and RESPOND states, the endpoint correctly reponds with Reset, while in the REQUEST/OPEN states, packets with option errors are just ignored. The packet sequence is as follows: Case 1: Endpoint A Endpoint B (CLOSED) (CLOSED) <---------------- REQUEST RESPONSE -----------------> (*1) (with invalid option) <---------------- RESET (with Reset Code 5, "Option Error") (*1) currently just ignored, no Reset is sent Case 2: Endpoint A Endpoint B (OPEN) (OPEN) DATA-ACK -----------------> (*2) (with invalid option) <---------------- RESET (with Reset Code 5, "Option Error") (*2) currently just ignored, no Reset is sent This patch fixes the problem, by generating a Reset instead of silently ignoring option errors.

This patch adds a direct probe request as first step in the association flow if data we have is not up to date. Motivation of this step is to make sure that the bss information we have is correct, since last scan could have been done a while ago, and beacons do not fully answer this need as there are potential differences between them and probe responses (e.g. WMM parameter element) Signed-off-by: NRon Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: NTomas Winkler <tomas.winkler@intel.com> Signed-off-by: NJohn W.
