2008-08-27ibmveth: fix bad UDP checksumsSantiago Leon
This patch fixes a ibmveth bug where bad UDP checksums are being transmitted when checksum offloading is enabled. The hypervisor does checksum offloading only on TCP packets, so ibmveth calls skb_checksum_help() for any other protocol. The bug happens because the packet is being modified after the DMA map, so we would need a memory barrier before making the hypervisor call. Reordering the code so that the DMA map happens after skb_checksum_help() has the additional advantage of fixing a DMA map leak if skb_checksum_help() where to fail.

2008-08-27dccp ccid-3: Replace lazy BUG_ON with conditionGerrit Renker
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: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-08-27dccp: Toggle debug output without module unloadingGerrit Renker
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. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-08-27dccp: Empty the write queue when disconnectingGerrit Renker
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()).

2008-08-27dccp: Fill in the Data fields for "Option Error" ResetsGerrit Renker
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: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-08-27dccp: Silently ignore options with nonsensical lengthsGerrit Renker
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: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-08-27dccp: Always generate a Reset in response to option errorsWei Yongjun
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.

2008-08-26mac80211: don't send empty extended rates IEJan-Espen Pettersen
The association request includes a list of supported data rates. 802.11b: 4 supported rates. 802.11g: 12 (8 + 4) supported rates. 802.11a: 8 supported rates. The rates tag of the assoc request has room for only 8 rates. In case of 802.11g an extended rate tag is appended. However in net/wireless/mlme.c an extended (empty) rate tag is also appended if the number of rates is exact 8. This empty (length=0) extended rates tag causes some APs to deny association with code 18 (unsupported rates). These APs include my ZyXEL G-570U, and according to Tomas Winkler som Cisco APs. 'If count == 8' has been used to check for the need for an extended rates tag. But count would also be equal to 8 if the for loop exited because of no more supported rates. Therefore a check for count being less than rates_len would seem more correct.

2008-08-26mac80211: Fix debugfs file add/del for netdevJouni Malinen
Previous version was using incorrect union structures for non-AP interfaces when adding and removing max_ratectrl_rateidx and force_unicast_rateidx entries. Depending on the vif type, this ended up in corrupting debugfs entries since the dentries inside different union structures ended up going being on top of eachother.. As the end result, debugfs files were being left behind with references to freed data (instant kernel oops on access) and directories were not removed properly when unloading mac80211 drivers. This patch fixes those issues by using only a single union structure based on the vif type. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2008-08-26mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOMJouni Malinen
The previous code was using IWEVCUSTOM to report IEs from AssocReq and AssocResp frames into user space. This can easily hit the 256 byte limit (IW_CUSTOM_MAX) with APs that include number of vendor IEs in AssocResp. This results in the event message not being sent and dmesg showing "wlan0 (WE) : Wireless Event too big (366)" type of errors. Convert mac80211 to use IWEVASSOCREQIE/IWEVASSOCRESPIE to avoid the issue of being unable to send association IEs as wireless events. These newer event types use binary encoding and larger maximum size (IW_GENERIC_IE_MAX = 1024), so the likelyhood of not being able to send the IEs is much smaller than with IWEVCUSTOM. As an extra benefit, the code is also quite a bit simpler since there is no need to allocate an extra buffer for hex encoding.
