2008-05-19tipc: Fix bug in topology server byte swapping routineAllan Stephens
This patch fixes TIPC's topology server so that it does byte swapping correctly when endianness conversion is required. (Note: This bug only impacted an application if it issues a subscription request to a topology server on another node, rather than the server on it's own node; since the topology server is normally not accessible by off-node applications, most TIPC applications were not impacted by the bug.)

2008-05-149p: fix error path during early mountEric Van Hensbergen
There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd transport separate from the core 9pnet code seemed like a good idea at the time, but in practice has caused more harm and confusion than good.

2008-05-149p: make cryptic unknown error from server less scaryEric Van Hensbergen

2008-05-14mac80211: Set IEEE80211_TXPD_REQ_TX_STATUS for all TX framesIvo van Doorn
All interfaces should set the IEEE80211_TXPD_REQ_TX_STATUS flag for all TX frames which will force the master interface to set the IEEE80211_TX_CTL_REQ_TX_STATUS flag. This in turn will allow drivers to check for that flag before reporting the TX status to mac80211. This is very usefull when frames (like beacons, RTS and CTS-to-self) should not be reported back to mac80211. Later we could add more extensive checks to exclude more frames from being reported, or let mac80211 decide if it wants the frame for status reporting or not. v2: Monitor interfaces should also set IEEE80211_TXPD_REQ_TX_STATUS Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

2008-05-14mac80211: proper STA info lockingJohannes Berg
As discussed earlier, we can unify locking in struct sta_info and use just a single spinlock protecting all members of the structure that need protection. Many don't, but one of the especially bad ones is the 'flags' member that can currently be clobbered when RX and TX is being processed on different CPUs at the same time. Because having four spinlocks for different, mostly exclusive parts of a single structure is overkill, this patch also kills the ampdu and mesh plink spinlocks and uses just a single one for everything. Because none of the spinlocks are nested, this is safe. It remains to be seen whether or not we should make the sta flags use atomic bit operations instead, for now though this is a safe thing and using atomic operations instead will be very simple using the new static inline functions this patch introduces for accessing sta->flags. Since spin_lock_bh() is used with this lock, there shouldn't be any contention even if aggregation is enabled at around the same time as both requires frame transmission/reception which is in a bh context.

2008-05-13tcp FRTO: work-around inorder receiversIlpo Järvinen
If receiver consumes segments successfully only in-order, FRTO fallback to conventional recovery produces RTO loop because FRTO's forward transmissions will always get dropped and need to be resent, yet by default they're not marked as lost (which are the only segments we will retransmit in CA_Loss). Price to pay about this is occassionally unnecessarily retransmitting the forward transmission(s). SACK blocks help a bit to avoid this, so it's mainly a concern for NewReno case though SACK is not fully immune either. This change has a side-effect of fixing SACKFRTO problem where it didn't have snd_nxt of the RTO time available anymore when fallback become necessary (this problem would have only occured when RTO would occur for two or more segments and ECE arrives in step 3; no need to figure out how to fix that unless the TODO item of selective behavior is considered in future).

2008-05-13tcp FRTO: Fix fallback to conventional recoveryIlpo Järvinen
It seems that commit 009a2e3e4ec ("[TCP] FRTO: Improve interoperability with other undo_marker users") run into another land-mine which caused fallback to conventional recovery to break: 1. Cumulative ACK arrives after FRTO retransmission 2. tcp_try_to_open sees zero retrans_out, clears retrans_stamp which should be kept like in CA_Loss state it would be 3. undo_marker change allowed tcp_packet_delayed to return true because of the cleared retrans_stamp once FRTO is terminated causing LossUndo to occur, which means all loss markings FRTO made are reverted. This means that the conventional recovery basically recovered one loss per RTT, which is not that efficient. It was quite unobvious that the undo_marker change broken something like this, I had a quite long session to track it down because of the non-intuitiviness of the bug (luckily I had a trivial reproducer at hand and I was also able to learn to use kprobes in the process as well :-)). This together with the NewReno+FRTO fix and FRTO in-order workaround this fixes Damon's problems, this and the first mentioned are enough to fix Bugzilla #10063.
