* ipvs: Fix IPv4 FWMARK virtual servicesSimon Horman2009-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the use of fwmarks to denote IPv4 virtual services which was unfortunately broken as a result of the integration of IPv6 support into IPVS, which was included in 2.6.28. The problem arises because fwmarks are stored in the 4th octet of a union nf_inet_addr .all, however in the case of IPv4 only the first octet, corresponding to .ip, is assigned and compared. In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always results in a value of 0 (32bits) being stored for IPv4. This means that one fwmark can be used, as it ends up being mapped to 0, but things break down when multiple fwmarks are used, as they all end up being mapped to 0. As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark in .ip, and comparing and storing .ip when fwmarks are used. This patch makes the assumption that in calls to ip_vs_ct_in_get() and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then we are dealing with an fwmark. I believe this is valid as ip_vs_in() does fairly strict filtering on the protocol and IPPROTO_IP should not be used in these calls unless explicitly passed when making these calls for fwmarks in ip_vs_sched_persist().

* bnx2: Fix panic in bnx2_poll_work().Michael Chan2009-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add barrier() to bnx2_get_hw_{tx|rx}_cons() to fix this issue: http://bugzilla.kernel.org/show_bug.cgi?id=12698 This issue was reported by multiple i386 users. Without barrier(), the compiled code looks like the following where %eax contains the address of the tx_cons or rx_cons in the DMA status block. The status block contents can change between the cmpb and the movzwl instruction. The driver would crash if the value was not 0xff during the cmpb instruction, but changed to 0xff during the movzwl instruction. 6828: 80 38 ff cmpb $0xff,(%eax) 682b: 0f b7 10 movzwl (%eax),%edx With the added barrier(), the compiled code now looks correct: 683d: 0f b7 10 movzwl (%eax),%edx 6840: 0f b6 c2 movzbl %dl,%eax 6843: 3d ff 00 00 00 cmp $0xff,%eax Thanks to Pascal de Bruijn <pmjdebruijn@pcode.nl> for reporting the problem and Holger Noefer <hnoefer@pironet-ndh.com> for patiently testing test patches for us.

| * wimax: oops: wimax_dev_add() is the only one that can initialize the stateInaky Perez-Gonzalez2009-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a new wimax_dev is created, it's state has to be __WIMAX_ST_NULL until wimax_dev_add() is succesfully called. This allows calls into the stack that happen before said time to be rejected. Until now, the state was being set (by mistake) to UNINITIALIZED, which was allowing calls such as wimax_report_rfkill_hw() to go through even when a call to wimax_dev_add() had failed; that was causing an oops when touching uninitialized data. This situation is normal when the device starts reporting state before the whole initialization has been completed. It just has to be dealt with.

* | Bluetooth: Move dev_set_name() to a context that can sleepMarcel Holtmann2009-05-05
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting the name of a sysfs device has to be done in a context that can actually sleep. It allocates its memory with GFP_KERNEL. Previously it was a static (size limited) string and that got changed to accommodate longer device names. So move the dev_set_name() just before calling device_add() which is executed in a work queue. This fixes the following error: [ 110.012125] BUG: sleeping function called from invalid context at mm/slub.c:1595 [ 110.012135] in_atomic(): 1, irqs_disabled(): 0, pid: 0, name: swapper [ 110.012141] 2 locks held by swapper/0: [ 110.012145] #0: (hci_task_lock){++.-.+}, at: [<ffffffffa01f822f>] hci_rx_task+0x2f/0x2d0 [bluetooth] [ 110.012173] #1: (&hdev->lock){+.-.+.}, at: [<ffffffffa01fb9e2>] hci_event_packet+0x72/0x25c0 [bluetooth] [ 110.012198] Pid: 0, comm: swapper Tainted: G W 2.6.30-rc4-g953cdaa #1 [ 110.012203] Call Trace: [ 110.012207] <IRQ> [<ffffffff8023eabd>] __might_sleep+0x14d/0x170 [ 110.012228] [<ffffffff802cfbe1>] __kmalloc+0x111/0x170 [ 110.012239] [<ffffffff803c2094>] kvasprintf+0x64/0xb0 [ 110.012248] [<ffffffff803b7a5b>] kobject_set_name_vargs+0x3b/0xa0 [ 110.012257] [<ffffffff80465326>] dev_set_name+0x76/0xa0 [ 110.012273] [<ffffffffa01fb9e2>] ? hci_event_packet+0x72/0x25c0 [bluetooth] [ 110.012289] [<ffffffffa01ffc1d>] hci_conn_add_sysfs+0x3d/0x70 [bluetooth] [ 110.012303] [<ffffffffa01fba2c>] hci_event_packet+0xbc/0x25c0 [bluetooth] [ 110.012312] [<ffffffff80516eb0>] ? sock_def_readable+0x80/0xa0 [ 110.012328] [<ffffffffa01fee0c>] ? hci_send_to_sock+0xfc/0x1c0 [bluetooth] [ 110.012343] [<ffffffff80516eb0>] ? sock_def_readable+0x80/0xa0 [ 110.012347] [<ffffffff805e88c5>] ? _read_unlock+0x75/0x80 [ 110.012354] [<ffffffffa01fee0c>] ? hci_send_to_sock+0xfc/0x1c0 [bluetooth] [ 110.012360] [<ffffffffa01f8403>] hci_rx_task+0x203/0x2d0 [bluetooth] [ 110.012365] [<ffffffff80250ab5>] tasklet_action+0xb5/0x160 [ 110.012369] [<ffffffff8025116c>] __do_softirq+0x9c/0x150 [ 110.012372] [<ffffffff805e850f>] ? _spin_unlock+0x3f/0x80 [ 110.012376] [<ffffffff8020cbbc>] call_softirq+0x1c/0x30 [ 110.012380] [<ffffffff8020f01d>] do_softirq+0x8d/0xe0 [ 110.012383] [<ffffffff80250df5>] irq_exit+0xc5/0xe0 [ 110.012386] [<ffffffff8020e71d>] do_IRQ+0x9d/0x120 [ 110.012389] [<ffffffff8020c3d3>] ret_from_intr+0x0/0xf [ 110.012391] <EOI> [<ffffffff80431832>] ? acpi_idle_enter_bm+0x264/0x2a6 [ 110.012399] [<ffffffff80431828>] ? acpi_idle_enter_bm+0x25a/0x2a6 [ 110.012403] [<ffffffff804f50d5>] ? cpuidle_idle_call+0xc5/0x130 [ 110.012407] [<ffffffff8020a4b4>] ? cpu_idle+0xc4/0x130 [ 110.012411] [<ffffffff805d2268>] ? rest_init+0x88/0xb0 [ 110.012416] [<ffffffff807e2fbd>] ? start_kernel+0x3b5/0x412 [ 110.012420] [<ffffffff807e2281>] ? x86_64_start_reservations+0x91/0xb5 [ 110.012424] [<ffffffff807e2394>] ? x86_64_start_kernel+0xef/0x11b Based on a report by Davide Pesavento <davidepesa@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Tested-by: Hugo Mildenberger <hugo.mildenberger@namir.de> Tested-by: Bing Zhao <bzhao@marvell.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem when you use 32 nodes in the cluster match: % iptables -I PREROUTING -t mangle -i eth0 -m cluster \ --cluster-total-nodes 32 --cluster-local-node 32 \ --cluster-hash-seed 0xdeadbeef -j MARK --set-mark 0xffff iptables: Invalid argument. Run `dmesg' for more information. % dmesg | tail -1 xt_cluster: this node mask cannot be higher than the total number of nodes The problem is related to this checking: if (info->node_mask >= (1 << info->total_nodes)) { printk(KERN_ERR "xt_cluster: this node mask cannot be " "higher than the total number of nodes\n"); return false; } (1 << 32) is 1. Thus, the checking fails. BTW, I said this before but I insist: I have only tested the cluster match with 2 nodes getting ~45% extra performance in an active-active setup. The maximum limit of 32 nodes is still completely arbitrary. I'd really appreciate if people that have more nodes in their setups let me know.

Without the lock there is possible race between processing a reply from CRDA and a driver calling wiphy_apply_custom_regulatory(). During the processing of the reply from CRDA we free last_request and wiphy_apply_custom_regulatory() eventually accesses an element from last_request in the through freq_reg_info_regd(). This is very difficult to reproduce (I haven't), it takes us 3 hours and you need to be banging hard, but the race is obvious by looking at the code. This should only affect those who use this caller, which currently is ath5k, ath9k, and ar9170.

| * | iwlwifi: update key flags at time key is setReinette Chatre2009-05-04

This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info().

The whole approach is actually fully broken and based on assumptions that are no longer valid. With the introduction of Simple Pairing support, the creation of low-level ACL links got changed. This change invalidates the reason why in the past two independent work queues have been used for adding/removing sysfs devices. The adding of the actual sysfs device is now postponed until the host controller successfully assigns an unique handle to that link. So the real synchronization happens inside the controller and not the host. The only left-over problem is that some internals of the sysfs device handling are not initialized ahead of time. This leaves potential access to invalid data and can cause various NULL pointer dereferences. To fix this a new function makes sure that all sysfs details are initialized when an connection attempt is made. The actual sysfs device is only registered when the connection has been successfully established. To avoid a race condition with the registration, the check if a device is registered has been moved into the removal work. As an extra protection two flush_work() calls are left in place to make sure a previous add/del work has been completed first.

This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.
