2010-03-30mac80211: move netdev queue enabling to correct spotJohannes Berg
"mac80211: fix skb buffering issue" still left a race between enabling the hardware queues and the virtual interface queues. In hindsight it's totally obvious that enabling the netdev queues for a hardware queue when the hardware queue is enabled is wrong, because it could well possible that we can fill the hw queue with packets we already have pending. Thus, we must only enable the netdev queues once all the pending packets have been processed and sent off to the device. In testing, I haven't been able to trigger this race condition, but it's clearly there, possibly only when aggregation is being enabled.

2010-03-16ath9k: fix BUG_ON triggered by PAE framesFelix Fietkau
When I initially stumbled upon sequence number problems with PAE frames in ath9k, I submitted a patch to remove all special cases for PAE frames and let them go through the normal transmit path. Out of concern about crypto incompatibility issues, this change was merged instead: commit 6c8afef551fef87a3bf24f8a74c69a7f2f72fc82 Author: Sujith <Sujith.Manoharan@atheros.com> Date: Tue Feb 9 10:07:00 2010 +0530 ath9k: Fix sequence numbers for PAE frames After a lot of testing, I'm able to reliably trigger a driver crash on rekeying with current versions with this change in place. It seems that the driver does not support sending out regular MPDUs with the same TID while an A-MPDU session is active. This leads to duplicate entries in the TID Tx buffer, which hits the following BUG_ON in ath_tx_addto_baw(): index = ATH_BA_INDEX(tid->seq_start, bf->bf_seqno); cindex = (tid->baw_head + index) & (ATH_TID_MAX_BUFS - 1); BUG_ON(tid->tx_buf[cindex] != NULL); I believe until we actually have a reproducible case of an incompatibility with another AP using no PAE special cases, we should simply get rid of this mess. This patch completely fixes my crash issues in STA mode and makes it stay connected without throughput drops or connectivity issues even when the AP is configured to a very short group rekey interval.

2010-03-10ath5k: fix I/Q calibration (for real)Bruno Randolf
I/Q calibration was completely broken, resulting in a high number of CRC errors on received packets. before i could see around 10% to 20% CRC errors, with this patch they are between 0% and 3%. 1.) the removal of the mask in commit "ath5k: Fix I/Q calibration (f1cf2dbd0f798b71b1590e7aca6647f2caef1649)" resulted in no mask beeing used when writing the I/Q values into the register. additional errors in the calculation of the values (see 2.) resulted too high numbers, exceeding the masks, so wrong values like 0xfffffffe were written. to be safe we should always use the bitmask when writing parts of a register. 2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we convert to a signed value later by substracting 128. this resulted in too low numbers for Q many times, which were limited to -16 by the boundary check later on. 3.) checked everything against the HAL sources and took over comments and minor optimizations from there. 4.) we can't use ENABLE_BITS when we want to write a number (the number can contain zeros). also always write the correction values first and set ENABLE bit last, like the HAL does.

2010-03-10ath5k: use fixed antenna for tx descriptorsBruno Randolf
when using a fixed antenna we should use the antenna number in all tx descriptors, otherwise the hardware will sometimes send the frame out on the other antenna. it seems like the hardware does not always respect the default antenna and diversity settings (esp. AR5K_STA_ID1_DEFAULT_ANTENNA). also i would like to note that antenna diversity does not always work correctly on 5414 (at least) when only one antenna is connected: for example all frames might be received on antenna A but still the HW tries to send on antenna B some times, causing packet loss. this is both verified with the antenna statistics output of the previous patch and a spectrum analyzer.

When we build it in the buffer without the SSID (wildcard) we don't arrive over 200 bytes, but the ucode still allows direct probe in addition because it has an internal buffer that is larger when it inserts the SSID...

2010-03-09iwl3945: fix memory corruptionReinette Chatre
Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory corruption problem. When initializing the clip groups the code was mistakenly using the iwlagn rate count, not the 3945 rate count. This resulted in more memory being written than was allocated. "iwlwifi: move 3945 clip groups to 3945 data" moved the location where the clip groups are stored and the impact is now severe in that the number of configured TX queues is modified. Previously the "temperature" field was overwritten, which did not seem to affect the operation. Fix this one instance where wrong rate count was used. I also noticed one more location where the iwlagn rate count was used to index an iwl3945 array, fix this. I also modified one location that modified the iwlagn rate count to obtain the iwl3945 rate count ... just use the iwl3945 rate count directly.

This check was present in TIPC 1.5/1.6, but was removed by accident during the development of TIPC 1.7; it has now been updated to account for new features present in TIPC 1.7 and reinserted into TIPC. The main benefit of this check is to filter out messages arriving from orphaned link endpoints, which can arise when a node exits the network and then re-enters it with a different TIPC network address (i.e. <Z.C.N> value).

2010-03-08tipc: fix endianness on tipc subscriber messagesNeil Horman
Remove htohl implementation from tipc I was working on forward porting the downstream commits for TIPC and ran accross this one: http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31e I was going to just take it, when I looked closer and noted what it was doing. This is basically a routine to byte swap fields of data in sent/received packets for tipc, dependent upon the receivers guessed endianness of the peer when a connection is established. Asside from just seeming silly to me, it appears to violate the latest RFC draft for tipc: http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt Which, according to section 4.2 and 4.3.3, requires that all fields of all commands be sent in network byte order. So instead of just taking this patch, instead I'm removing the htohl function and replacing the calls with calls to ntohl in the rx path and htonl in the send path. As part of this fix, I'm also changing the subscr_cancel function, which searches the list of subscribers, using a memcmp of the entire subscriber list, for the entry to tear down. unfortunately it memcmps the entire tipc_subscr structure which has several bits that are private to the local side, so nothing will ever match. section 5.2 of the draft spec indicates the <type,upper,lower> tuple should uniquely identify a subscriber, so convert subscr_cancel to just match on those fields (properly endian swapped). I've tested this using the tipc test suite, and its passed without issue. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-03-08net: fix route cache rebuildsEric Dumazet
We added an automatic route cache rebuilding in commit 1080d709fb9d8cd43 but had to correct few bugs. One of the assumption of original patch, was that entries where kept sorted in a given way. This assumption is known to be wrong (commit 1ddbcb005c395518 gave an explanation of this and corrected a leak) and expensive to respect. Paweł Staszewski reported to me one of his machine got its routing cache disabled after few messages like : [ 2677.850065] Route hash chain too long! [ 2677.850080] Adjust your secret_interval! [82839.662993] Route hash chain too long! [82839.662996] Adjust your secret_interval! [155843.731650] Route hash chain too long! [155843.731664] Adjust your secret_interval!

This is because rt_intern_hash() might be fooled when computing a chain length, because multiple entries with same keys can differ because of TOS (or mark/oif) bits. In the rare case the fast algorithm see a too long chain, and before taking expensive path, we call a helper function in order to not count duplicates of same routes, that only differ with tos/mark/oif bits. This helper works with data already in cpu cache and is not be very expensive, despite its O(N^2) implementation. Paweł Staszewski sucessfully tested this patch on his loaded router.

IPV6_PREFER_SRC_xxx definitions: | #define IPV6_PREFER_SRC_TMP 0x0001 | #define IPV6_PREFER_SRC_PUBLIC 0x0002 | #define IPV6_PREFER_SRC_COA 0x0004 RT6_LOOKUP_F_xxx definitions: | #define RT6_LOOKUP_F_SRCPREF_TMP 0x00000008 | #define RT6_LOOKUP_F_SRCPREF_PUBLIC 0x00000010 | #define RT6_LOOKUP_F_SRCPREF_COA 0x00000020 So, we can translate between these two groups by shift operation instead of multiple 'if's.

2010-03-07cpmac: fallback to switch mode if no PHY chip foundFlorian Fainelli
If we were unable to detect a PHY on any of the MDIO bus id we tried instead of bailing out with -ENODEV, assume the MAC is connected to a switch and use MDIO bus 0. This unbreaks quite a lot of devices out there whose switch cannot be detected. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-03-07cpmac: fix the receiving of 802.1q framesFlorian Fainelli
Despite what the comment above CPMAC_SKB_SIZE says, the hardware also needs to account for the FCS length in a received frame. This patch fix the receiving of 802.1q frames which have 4 more bytes. While at it unhardcode the definition and use the one from if_vlan.h. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
