| * sctp: on T3_RTX retransmit all the in-flight chunksAndrei Pelinescu-Onciul2009-11-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When retransmitting due to T3 timeout, retransmit all the in-flight chunks for the corresponding transport/path, including chunks sent less then 1 rto ago. This is the correct behaviour according to rfc4960 section 6.3.3 E3 and "Note: Any DATA chunks that were sent to the address for which the T3-rtx timer expired but did not fit in one MTU (rule E3 above) should be marked for retransmission and sent as soon as cwnd allows (normally, when a SACK arrives). ". This fixes problems when more then one path is present and the T3 retransmission of the first chunk that timeouts stops the T3 timer for the initial active path, leaving all the other in-flight chunks waiting forever or until a new chunk is transmitted on the same path and timeouts (and this will happen only if the cwnd allows sending new chunks, but since cwnd was dropped to MTU by the timeout => it will wait until the first heartbeat). Example: 10 packets in flight, sent at 0.1 s intervals on the primary path. The primary path is down and the first packet timeouts. The first packet is retransmitted on another path, the T3 timer for the primary path is stopped and cwnd is set to MTU. All the other 9 in-flight packets will not be retransmitted (unless more new packets are sent on the primary path which depend on cwnd allowing it, and even in this case the 9 packets will be retransmitted only after a new packet timeouts which even in the best case would be more then RTO). This commit reverts d0ce92910bc04e107b2f3f2048f07e94f570035d and also removes the now unused transport->last_rto, introduced in b6157d8e03e1e780660a328f7183bcbfa4a93a19. p.s The problem is not only when multiple paths are there. It can happen in a single homed environment. If the application stops sending data, it possible to have a hung association.

| * | sctp: Update max.burst implementationVlad Yasevich2009-11-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of max.burst ends up limiting new data during cwnd decay period. The decay is happening becuase the connection is idle and we are allowed to fill the congestion window. The point of max.burst is to limit micro-bursts in response to large acks. This still happens, as max.burst is still applied to each transmit opportunity. It will also apply if a very large send is made (greater then allowed by burst).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent attempt to remove deprecated socket options demonstrated that removing options from the enum space will have severe binary compatibility issues. The reason is that it changes the subsequent enum space and causes option values to be redefined. To solve this, and to get rid of the ugly double statements for every option, we simply convert to the #define scheme. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
| * | sctp: Remove useless last_time_used variableVlad Yasevich2009-11-231-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The transport last_time_used variable is rather useless. It was only used when determining if CWND needs to be updated due to idle transport. However, idle transport detection was based on a Heartbeat timer and last_time_used was not incremented when sending Heartbeats. As a result the check for cwnd reduction was always true. We can get rid of the variable and just base our cwnd manipulation on the HB timer (like the code comment sais). We also have to call into the cwnd manipulation function regardless of whether HBs are enabled or not. That way we will detect idle transports if the user has disabled Heartbeats.

| * | mac80211: avoid spurious deauth frames/messagesJohannes Berg2009-11-191-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With WEXT, it happens frequently that the SME requests an authentication but then deauthenticates right away because some new parameters came along. Every time this happens we print a deauth message and send a deauth frame, but both of that is rather confusing. Avoid it by aborting the authentication process silently, and telling cfg80211 about that. The patch looks larger than it really is: __cfg80211_auth_remove() is split out from cfg80211_send_auth_timeout(), there's no new code except __cfg80211_auth_canceled() (a one-liner) and the mac80211 bits (7 new lines of code).

This isn't really necessary, only the injected frames need TX status (the latter for hostapd) so move setting this flag. The rate control algorithms also need TX status, but they don't require it. Also, rt2x00 uses that bit for its own purposes and seems to require it being set for all frames, but that can be fixed in rt2x00. This doesn't really change anything for any drivers but in the future drivers using hw-rate control may opt to not report TX status for frames that don't have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

It cannot work, however, because in 802.11 networks all packets need to be acknowledged and as such need to be sent to the right address. Promiscuous doesn't help here. The wireless address format used for these links has only space for three addresses, the * transmitter, which must be equal to the sender (origin) * receiver (on the wireless medium), which is the AP in the case of managed mode * the recipient (destination), which is on the APs local network segment In an IBSS, it is similar, but the receiver and recipient must match and the third address is used as the BSSID. To avoid such mistakes in the future, disallow adding a wireless interface to a bridge. Felix has recently added a four-address mode to the AP and client side that can be used (after negotiating that it is possible, which must happen out-of-band by setting up both sides) for bridging, so allow that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's very likely that not many devices will support four-address mode in station or AP mode so introduce capability bits for both modes, set them in mac80211 and check them when userspace tries to use the mode. Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly. However, keep track of use_4addr for station mode in mac80211 to avoid all the derefs. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

This is obviously a problem for distribution kernels who want to support both in the same image. After some discussions with Rafael and others the only problem is with parallel memory hotadd or removal while a hibernation operation is in process. It was also working for s390 before. This patch removes the Kconfig level exclusion, and simply makes the memory add / remove functions grab the pm_mutex to exclude against hibernation. Fixes a regression - old kernels didn't exclude memory hotadd and hibernation.

However, rewriting the code to use an index into a small static array seemed like a more elegant solution. Signed-off-by: Martin K.

They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot rely on buffer dirty bits during fsync because pdflush can come before fsync is called and clear dirty bits without forcing a transaction commit. What we do is that we track which transaction has last changed the inode and which transaction last changed allocation and force it to disk on fsync.
