2011-10-04tcp: properly update lost_cnt_hint during shiftingYan, Zheng
lost_skb_hint is used by tcp_mark_head_lost() to mark the first unhandled skb. lost_cnt_hint is the number of packets or sacked packets before the lost_skb_hint; When shifting a skb that is before the lost_skb_hint, if tcp_is_fack() is ture, the skb has already been counted in the lost_cnt_hint; if tcp_is_fack() is false, tcp_sacktag_one() will increase the lost_cnt_hint. So tcp_shifted_skb() does not need to adjust the lost_cnt_hint by itself. When shifting a skb that is equal to lost_skb_hint, the shifted packets will not be counted by tcp_mark_head_lost(). So tcp_shifted_skb() should adjust the lost_cnt_hint even tcp_is_fack(tp) is true. Signed-off-by: Zheng Yan <zheng.z.yan@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-04PCI: Disable MPS configuration by defaultJon Mason
Add the ability to disable PCI-E MPS turning and using the BIOS configured MPS defaults. Due to the number of issues recently discovered on some x86 chipsets, make this the default behavior. Also, add the option for peer to peer DMA MPS configuration. Peer to peer DMA is outside the scope of this patch, but MPS configuration could prevent it from working by having the MPS on one root port different than the MPS on another. To work around this, simply make the system wide MPS the smallest possible value (128B).

2011-10-03lis3: fix regression of HP DriveGuard with 8bit chipTakashi Iwai
Commit 2a7fade7e03 ("hwmon: lis3: Power on corrections") caused a regression on HP laptops with 8bit chip. Writing CTRL2_BOOT_8B bit seems clearing the BIOS setup, and no proper interrupt for DriveGuard will be triggered any more. Since the init code there is basically only for embedded devices, put a pdata check so that the problematic initialization will be skipped for hp_accel stuff.

2011-10-03ide-disk: Fix request requeuingBorislav Petkov
Simon Kirby reported that on his RAID setup with idedisk underneath the box OOMs after a couple of days of runtime. Running with CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally allocates an ide_cmd struct. However, ide_requeue_and_plug() can be called more than once per request, either from the request issue or the IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn() repeatedly, allocating a struct ide_cmd everytime and "forgetting" the previous pointer. Make sure the code reuses the old allocated chunk.

2011-10-03make PACKET_STATISTICS getsockopt report consistently between ring and non-ringWillem de Bruijn
This is a minor change. Up until kernel 2.6.32, getsockopt(fd, SOL_PACKET, PACKET_STATISTICS, ...) would return total and dropped packets since its last invocation. The introduction of socket queue overflow reporting [1] changed drop rate calculation in the normal packet socket path, but not when using a packet ring. As a result, the getsockopt now returns different statistics depending on the reception method used. With a ring, it still returns the count since the last call, as counts are incremented in tpacket_rcv and reset in getsockopt. Without a ring, it returns 0 if no drops occurred since the last getsockopt and the total drops over the lifespan of the socket otherwise. The culprit is this line in packet_rcv, executed on a drop: drop_n_acct: po->stats.tp_drops = atomic_inc_return(&sk->sk_drops); As it shows, the new drop number it taken from the socket drop counter, which is not reset at getsockopt. I put together a small example that demonstrates the issue [2]. It runs for 10 seconds and overflows the queue/ring on every odd second. The reported drop rates are: ring: 16, 0, 16, 0, 16, ... non-ring: 0, 15, 0, 30, 0, 46, 0, 60, 0 , 74. Note how the even ring counts monotonically increase. Because the getsockopt adds tp_drops to tp_packets, total counts are similarly reported cumulatively. Long story short, reinstating the original code, as the below patch does, fixes the issue at the cost of additional per-packet cycles. Another solution that does not introduce per-packet overhead is be to keep the current data path, record the value of sk_drops at getsockopt() at call N in a new field in struct packetsock and subtract that when reporting at call N+1. I'll be happy to code that, instead, it's just more messy.

2011-10-03net: xen-netback: correctly restart Tx after a VM restore/migrateDavid Vrabel
If a VM is saved and restored (or migrated) the netback driver will no longer process any Tx packets from the frontend. xenvif_up() does not schedule the processing of any pending Tx requests from the front end because the carrier is off. Without this initial kick the frontend just adds Tx requests to the ring without raising an event (until the ring is full). This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net: xen-netback: convert to hw_features) which reordered the calls to xenvif_up() and netif_carrier_on() in xenvif_connect().

2011-10-03bonding: properly stop queuing work when requestedAndy Gospodarek
During a test where a pair of bonding interfaces using ARP monitoring were both brought up and torn down (with an rmmod) repeatedly, a panic in the timer code was noticed. I tracked this down and determined that any of the bonding functions that ran as workqueue handlers and requeued more work might not properly exit when the module was removed. There was a flag protected by the bond lock called kill_timers that is set when the interface goes down or the module is removed, but many of the functions that monitor link status now unlock the bond lock to take rtnl first. There is a chance that another CPU running the rmmod could get the lock and set kill_timers after the first check has passed. This patch does not allow any function to queue work that will make itself run unless kill_timers is not set. I also noticed while doing this work that bond_resend_igmp_join_requests did not have a check for kill_timers, so I added the needed call there as well.

When a wide port is being utilized to a target, if one disables only one of the phys, we get an OS crash: BUG: unable to handle kernel NULL pointer dereference at 0000000000000238 IP: [<ffffffff814ca9b1>] mutex_lock+0x21/0x50 PGD 4103f5067 PUD 41dba9067 PMD 0 Oops: 0002 [#1] SMP last sysfs file: /sys/bus/pci/slots/5/address CPU 0 Modules linked in: pm8001(U) ses enclosure fuse nfsd exportfs autofs4 ipmi_devintf ipmi_si ipmi_msghandler nfs lockd fscache nfs_acl auth_rpcgss 8021q fcoe libfcoe garp libfc scsi_transport_fc stp scsi_tgt llc sunrpc cpufreq_ondemand acpi_cpufreq freq_table ipv6 sr_mod cdrom dm_mirror dm_region_hash dm_log uinput sg i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support e1000e mlx4_ib ib_mad ib_core mlx4_en mlx4_core ext3 jbd mbcache sd_mod crc_t10dif usb_storage ata_generic pata_acpi ata_piix libsas(U) scsi_transport_sas dm_mod [last unloaded: pm8001] Modules linked in: pm8001(U) ses enclosure fuse nfsd exportfs autofs4 ipmi_devintf ipmi_si ipmi_msghandler nfs lockd fscache nfs_acl auth_rpcgss 8021q fcoe libfcoe garp libfc scsi_transport_fc stp scsi_tgt llc sunrpc cpufreq_ondemand acpi_cpufreq freq_table ipv6 sr_mod cdrom dm_mirror dm_region_hash dm_log uinput sg i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support e1000e mlx4_ib ib_mad ib_core mlx4_en mlx4_core ext3 jbd mbcache sd_mod crc_t10dif usb_storage ata_generic pata_acpi ata_piix libsas(U) scsi_transport_sas dm_mod [last unloaded: pm8001] Pid: 5146, comm: scsi_wq_5 Not tainted 2.6.32-71.29.1.el6.lustre.7.x86_64 #1 Storage Server RIP: 0010:[<ffffffff814ca9b1>] [<ffffffff814ca9b1>] mutex_lock+0x21/0x50 RSP: 0018:ffff8803e4e33d30 EFLAGS: 00010246 RAX: 0000000000000000 RBX: 0000000000000238 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff8803e664c800 RDI: 0000000000000238 RBP: ffff8803e4e33d40 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000001 R12: 0000000000000000 R13: 0000000000000238 R14: ffff88041acb7200 R15: ffff88041c51ada0 FS: 0000000000000000(0000) GS:ffff880028200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 0000000000000238 CR3: 0000000410143000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process scsi_wq_5 (pid: 5146, threadinfo ffff8803e4e32000, task ffff8803e4e294a0) Stack: ffff8803e664c800 0000000000000000 ffff8803e4e33d70 ffffffffa001f06e <0> ffff8803e4e33d60 ffff88041c51ada0 ffff88041acb7200 ffff88041bc0aa00 <0> ffff8803e4e33d90 ffffffffa0032b6c 0000000000000014 ffff88041acb7200 Call Trace: [<ffffffffa001f06e>] sas_port_delete_phy+0x2e/0xa0 [scsi_transport_sas] [<ffffffffa0032b6c>] sas_unregister_devs_sas_addr+0xac/0xe0 [libsas] [<ffffffffa0034914>] sas_ex_revalidate_domain+0x204/0x330 [libsas] [<ffffffffa00307f0>] ? sas_revalidate_domain+0x0/0x90 [libsas] [<ffffffffa0030855>] sas_revalidate_domain+0x65/0x90 [libsas] [<ffffffff8108c7d0>] worker_thread+0x170/0x2a0 [<ffffffff81091ea0>] ? autoremove_wake_function+0x0/0x40 [<ffffffff8108c660>] ? worker_thread+0x0/0x2a0 [<ffffffff81091b36>] kthread+0x96/0xa0 [<ffffffff810141ca>] child_rip+0xa/0x20 [<ffffffff81091aa0>] ? kthread+0x0/0xa0 [<ffffffff810141c0>] ? child_rip+0x0/0x20 Code: ff ff 85 c0 75 ed eb d6 66 90 55 48 89 e5 48 83 ec 10 48 89 1c 24 4c 89 64 24 08 0f 1f 44 00 00 48 89 fb e8 92 f4 ff ff 48 89 df <f0> ff 0f 79 05 e8 25 00 00 00 65 48 8b 04 25 08 cc 00 00 48 2d RIP [<ffffffff814ca9b1>] mutex_lock+0x21/0x50 RSP <ffff8803e4e33d30> CR2: 0000000000000238 The following patch is admittedly a band-aid, and does not solve the root cause, but it still is a good candidate for hardening as a pointer check before reference.

2011-10-02ASoC: use a valid device for dev_err() in ZyloniteArnd Bergmann
A recent conversion has introduced references to &pdev->dev, which does not actually exist in all the contexts it's used in. Replace this with card->dev where necessary, in order to let the driver build again.

2011-10-02[SCSI] qla2xxx: Fix crash in qla2x00_abort_all_cmds() on unloadRoland Dreier
I hit a crash in qla2x00_abort_all_cmds() if the qla2xxx module is unloaded right after it is loaded. I debugged this down to the abort handling improperly treating a command of type SRB_ADISC_CMD as if it had a bsg_job to complete when that command actually uses the iocb_cmd part of the union. (I guess to hit this one has to unload the module while the async FC initialization is still in progress) It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT, SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.
