| | | | | | | | | This reverts commit 1235f504aaba2ebeabc863fdb3ceac764a317d47. It causes regressions worse than the problem it was trying to fix. Eric will try to solve the problem another way. Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: remove sysctl jiffies conversion on gc_elasticity and min_adv_mssMin Zhang2010-08-141-2/+2
| | | | | | | | | | | | | | sysctl output ipv6 gc_elasticity and min_adv_mss as values divided by HZ. However, they are not in unit of jiffies, since ip6_rt_min_advmss refers to packet size and ip6_rt_fc_elasticity is used as scaler as in expire>>ip6_rt_gc_elasticity, so replace the jiffies conversion handler will regular handler for them. This has impact on scripts that are currently working assuming the divide by HZ, will yield different results with this patch in place.

* can: add limit for nframes and clean up signed/unsigned variablesOliver Hartkopp2010-08-111-14/+27
| | | | | | | | | | | | | | | | This patch adds a limit for nframes as the number of frames in TX_SETUP and RX_SETUP are derived from a single byte multiplex value by default. Use-cases that would require to send/filter more than 256 CAN frames should be implemented in userspace for complexity reasons anyway. Additionally the assignments of unsigned values from userspace to signed values in kernelspace and vice versa are fixed by using unsigned values in kernelspace consistently.

| | * Bluetooth: Use 3-DH5 payload size for default ERTM max PDU sizeMat Martineau2010-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous value of 672 for L2CAP_DEFAULT_MAX_PDU_SIZE is based on the default L2CAP MTU. That default MTU is calculated from the size of two DH5 packets, minus ACL and L2CAP b-frame header overhead. ERTM is used with newer basebands that typically support larger 3-DH5 packets, and i-frames and s-frames have more header overhead. With clean RF conditions, basebands will typically attempt to use 1021-byte 3-DH5 packets for maximum throughput. Adjusting for 2 bytes of ACL headers plus 10 bytes of worst-case L2CAP headers yields 1009 bytes of payload. This PDU size imposes less overhead for header bytes and gives the baseband the option to choose 3-DH5 packets, but is small enough for ERTM traffic to interleave well with other L2CAP or SCO data. 672-byte payloads do not allow the most efficient over-the-air packet choice, and cannot achieve maximum throughput over BR/EDR.

| | * Bluetooth: Fix incorrect setting of remote_tx_win for L2CAP ERTMMat Martineau2010-08-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remote_tx_win is intended to be set on receipt of an L2CAP configuration request. The value is used to determine the size of the transmit window on the remote side of an ERTM connection, so L2CAP can stop sending frames when that remote window is full. An incorrect remote_tx_win value will cause the stack to not fully utilize the tx window (performance impact), or to overfill the remote tx window (causing dropped frames or a disconnect). This patch removes an extra setting of remote_tx_win when a configuration response is received. The transmit window has a different meaning in a response - it is an informational value less than or equal to the local tx_win.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Incoming configuration values must be converted to native CPU order before use. This fixes a bug where a little-endian MPS value is compared to a native CPU value. On big-endian processors, this can cause ERTM and streaming mode segmentation to produce PDUs that are larger than the remote stack is expecting, or that would produce fragmented skbs that the current FCS code cannot handle.

| * | iwlagn: fix rts cts protectionJohannes Berg2010-08-0911-133/+87

In order to fix all of this, we need to take a step back and see what we need to achieve: * we need RTS/CTS protection if requested by the AP for the BSS, mac80211 tells us this * in that case, CTS-to-self should only be enabled when mac80211 tells us * additionally, as a hardware workaround, on some devices we have to protect aggregated frames with RTS To achieve the first two items, set up the RXON accordingly and set the protection required flag in the transmit command when mac80211 requests protection for the frame. To achieve the last item, set the rate-control RTS-requested flag for all stations that we have aggregation sessions with, and set the protection required flag when sending aggregated frames (on those devices where this is required). Since otherwise bugs can occur, do not allow the user to override the RTS-for-aggregation setting from sysfs any more. Finally, also clean up the way all these flags get set in the driver and move everything into the device-specific functions.

* e100/e1000*/igb*/ixgb*: Add missing read memory barrierJeff Kirsher2010-08-088-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were seeing faults in the solos-pci receive tasklet when packets arrived for a VCC which was currently being closed: [18842.727906] EIP: [<e082f490>] br2684_push+0x19/0x234 [br2684] SS:ESP 0068:dfb89d14 [18845.090712] [<c13ecff3>] ? do_page_fault+0x0/0x2e1 [18845.120042] [<e082f490>] ? br2684_push+0x19/0x234 [br2684] [18845.153530] [<e084fa13>] solos_bh+0x28b/0x7c8 [solos_pci] [18845.186488] [<e084f711>] ? solos_irq+0x2d/0x51 [solos_pci] [18845.219960] [<c100387b>] ? handle_irq+0x3b/0x48 [18845.247732] [<c10265cb>] ? irq_exit+0x34/0x57 [18845.274437] [<c1025720>] tasklet_action+0x42/0x69 [18845.303247] [<c102643f>] __do_softirq+0x8e/0x129 [18845.331540] [<c10264ff>] do_softirq+0x25/0x2a [18845.358274] [<c102664c>] _local_bh_enable_ip+0x5e/0x6a [18845.389677] [<c102666d>] local_bh_enable+0xb/0xe [18845.417944] [<e08490a8>] ppp_unregister_channel+0x32/0xbb [ppp_generic] [18845.458193] [<e08731ad>] pppox_unbind_sock+0x18/0x1f [pppox] This patch uses an RCU-inspired approach to fix it. In the RX tasklet's find_vcc() function we first refuse to use a VCC which already has the ATM_VF_READY bit cleared. And in the VCC close function, we synchronise with the tasklet to ensure that it can't still be using the VCC before we continue and allow the VCC to be destroyed.

* pkt_sched: Fix sch_sfq vs tcf_bind_filter oopsJarek Poplawski2010-08-071-0/+7
| | | | | | | | | | | | | Since there was added ->tcf_chain() method without ->bind_tcf() to sch_sfq class options, there is oops when a filter is added with the classid parameter.

* net: disable preemption before call smp_processor_id()Changli Gao2010-08-071-0/+2
| | | | | | | | | | | Although netif_rx() isn't expected to be called in process context with preemption enabled, it'd better handle this case. And this is why get_cpu() is used in the non-RPS #ifdef branch. If tree RCU is selected, rcu_read_lock() won't disable preemption, so preempt_disable() should be called explictly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | spin_is_locked() can return zero on some (UP?) configurations because locks don't exist, and that causes an endless amount of warnings. Use lockdep_assert_held() instead, which has two advantages: 1) it verifies the current task is holding the lock or mutex 2) it compiles away completely when lockdep is not enabled Cc: stable@kernel.org [2.6.34+, maybe only parts of patch] Reported-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
