2010-12-16n_gsm: Fix message length handling when building headerKen Mills
Fix message length handling when building header When the message length is greater than 127, the length field in the header is built incorrectly. According to the spec, when the length is less than 128 the length field is a single byte formatted as: bbbbbbb1. When it is greater than 127 then the field is two bytes of the format: bbbbbbb0 bbbbbbbb.

2010-12-16bonding/vlan: Fix mangled NAs on slaves without VLAN tag insertionBen Hutchings
bond_na_send() attempts to insert a VLAN tag in between building and sending packets of the respective formats. If the slave does not implement hardware VLAN tag insertion then vlan_put_tag() will mangle the network-layer header because the Ethernet header is not present at this point (unlike in bond_arp_send()). Fix this by adding the tag out-of-line and relying on dev_hard_start_xmit() to insert it inline if necessary.

2010-12-16bonding: Change active slave quietly when bond is downBen Hutchings
bond_change_active_slave() may be called when a slave is added, even if the bond has not been brought up yet. It may then attempt to send packets, and further it may use mcast_work which is uninitialised before the bond is brought up. Add the necessary checks for netif_running(bond->dev).

2010-12-16bonding/vlan: Remove redundant VLAN tag insertion logicBen Hutchings
A bond may have a mixture of slave devices with and without hardware VLAN tag insertion capability. Therefore it always claims this capability and performs software VLAN tag insertion if the slave does not. Since commit 7b9c60903714bf0a19d746b228864bad3497284e, this has also been done by dev_hard_start_xmit(). The result is that VLAN- tagged skbs are now double-tagged when transmitted through slave devices without hardware VLAN tag insertion! Remove the now-redundant logic from bond_dev_queue_xmit().

2010-12-16ipv6: delete expired route in ip6_pmtu_deliverAndrey Vagin
The first big packets sent to a "low-MTU" client correctly triggers the creation of a temporary route containing the reduced MTU. But after the temporary route has expired, new ICMP6 "packet too big" will be sent, rt6_pmtu_discovery will find the previous EXPIRED route check that its mtu isn't bigger then in icmp packet and do nothing before the temporary route will not deleted by gc. I make the simple experiment: while :; do time ( dd if=/dev/zero bs=10K count=1 | ssh hostname dd of=/dev/null ) || break; done The "time" reports real 0m0.197s if a temporary route isn't expired, but it reports real 0m52.837s (!!!!) immediately after a temporare route has expired.

2010-12-16ath5k: Fix surveyBruno Randolf
The old survey implementation was broken and returned nonsense data. Clear cycle counters and survey data on reset. Since the cycle counters easily overflow it's better to keep a local version of collected survey data (in ms resolution, instead of clockrate) and update this every time survey is retrieved. If survey is retrieved often enough to avoid cycle counter overflows this works fine, otherwise we could update survey more often, like ath9k does. Still only the survey for the current channel is kept. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-12-16cfg80211: fix null pointer dereference with a custom regulatory requestLuis R. Rodriguez
Once we moved the core regulatory request to the queue and let the scheduler process it last_request will have been left NULL until the schedular decides to process the first request. When this happens and we are loading a driver with a custom regulatory request like all Atheros drivers we end up with a NULL pointer dereference. We fix this by checking if the request was a custom one.

2010-12-16nl80211: Add notification for dropped Deauth/DisassocJouni Malinen
Add a new notification to indicate that a received, unprotected Deauthentication or Disassociation frame was dropped due to management frame protection being in use. This notification is needed to allow user space (e.g., wpa_supplicant) to implement SA Query procedure to recover from association state mismatch between an AP and STA. This is needed to avoid getting stuck in non-working state when MFP (IEEE 802.11w) is used and a protected Deauthentication or Disassociation frame is dropped for any reason. After that, the station would silently discard any unprotected Deauthentication or Disassociation frame that could be indicating that the AP does not have association for the STA (when the Reason Code would be 6 or 7). IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

I am about to commit: http://sourceware.org/ml/binutils/2010-10/msg00033.html that fixes a problem with the LD/SD macro currently implemented by GAS for the o32 ABI in an inconsistent way. This is best illustrated with a simple program, which I'm copying here from the message above for easier reference: $ cat ld.s ld $5,32767($4) ld $5,32768($4) This gets assebled into the following output: $ mips-linux-as -32 -mips3 -o ld.o ld.s $ mips-linux-objdump -d ld.o ld.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: dc857fff ld a1,32767(a0) 4: 3c010001 lui at,0x1 8: 00810821 addu at,a0,at c: 8c258000 lw a1,-32768(at) 10: 8c268004 lw a2,-32764(at) ... Oops! The GAS fix makes the macro behave in a consistent way and pairs of LW/SW instructions to be output as appropriate regardless of the size of the offset associated with the address used. The machine instruction is still available, but to reach it macros have to be disabled first. This has a side effect of requiring the use of a machine-addressable memory operand. As some platforms require 64-bit operations for accesses to some I/O registers LD/SD instructions are used in a couple of places in Linux regardless of the ABI selected. Here's a fix for some pieces of code affected I've been able to track down. The fix should be backwards compatible with all supported binutils releases in existence and can be used as a reference for any other places or off-tree code. The use of the "R" constraint guarantees a machine-addressable operand. Signed-off-by: Maciej W.

2010-12-16SSB: Fix nvram_get on BCM47xx platformHauke Mehrtens
The nvram_get function was never in the mainline kernel, it only existed in an external OpenWrt patch. Use nvram_getenv function, which is in mainline and use an include instead of an extra function declaration. et0macaddr contains the mac address in text from like 00:11:22:33:44:55. We have to parse it before adding it into macaddr. nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h through the MIPS git tree and will be available soon. It will not build now without nvram_parse_macaddr, but it hasn't before either.

2010-12-16MIPS: Fix CP0 COUNTER clockevent raceKevin Cernekee
Consider the following test case: write_c0_compare(read_c0_count()); Even if the counter doesn't increment during execution, this might not generate an interrupt until the counter wraps around. The CPU may perform the comparison each time CP0 COUNT increments, not when CP0 COMPARE is written. If mips_next_event() is called with a very small delta, and CP0 COUNT increments during the calculation of "cnt += delta", it is possible that CP0 COMPARE will be written with the current value of CP0 COUNT. If this is detected, the function should return -ETIME, to indicate that the interrupt might not have actually gotten scheduled.
