2008-11-15[SCSI] dpt_i2o: fix transferred data length for scsi_set_resid()Miquel van Smoorenburg
dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which should contain the length in bytes of the transferred data. This would be correct if reply was a u32 *. However it is a void * here, so we need to read the value at (reply+20) instead. The value at (reply+5) is usually 0xff0000, which is apparently 'large enough' and didn't cause any trouble until 2.6.27 where commit 427e59f09fdba387547106de7bab980b7fff77be Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Sat Mar 8 18:24:17 2008 -0600 [SCSI] make use of the residue value caused this to become visible through e.g. iostat -x .

2008-11-14libata: improve phantom device detectionTejun Heo
Currently libata uses four methods to detect device presence. 1. PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

2008-11-14V4L/DVB (9624): CVE-2008-5033: fix OOPS on tvaudio when controlling bass/trebleMauro Carvalho Chehab
This bug were supposed to be fixed by 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1, where a call to NULL happens. Not all tvaudio chips allow controlling bass/treble. So, the driver has a table with a flag to indicate if the chip does support it. Unfortunately, the handling of this logic were broken for a very long time (probably since the first module version). Due to that, an OOPS were generated for devices that don't support bass/treble. This were the resulting OOPS message before the patch, with debug messages enabled: tvaudio' 1-005b: VIDIOC_S_CTRL BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<00000000>] *pde = 22fda067 *pte = 00000000 Oops: 0000 [#1] SMP Modules linked in: snd_hda_intel snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_hwdep snd soundcore tuner_simple tuner_types tea5767 tuner tvaudio bttv bridgebnep rfcomm l2cap bluetooth it87 hwmon_vid hwmon fuse sunrpc ipt_REJECT nf_conntrack_ipv4 iptable_filter ip_tables ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables x_tables ipv6 dm_mirrordm_multipath dm_mod configfs videodev v4l1_compat ir_common 8139cp compat_ioctl32 v4l2_common 8139too videobuf_dma_sg videobuf_core mii btcx_risc tveeprom i915 button snd_page_alloc serio_raw drm pcspkr i2c_algo_bit i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sr_mod cdrom sg ata_generic pata_acpi ata_piix libata sd_mod scsi_mod ext3 jbdmbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: soundcore] Pid: 15413, comm: qv4l2 Not tainted (2.6.25.14-108.fc9.i686 #1) EIP: 0060:[<00000000>] EFLAGS: 00210246 CPU: 0 EIP is at 0x0 EAX: 00008000 EBX: ebd21600 ECX: e2fd9ec4 EDX: 00200046 ESI: f8c0f0c4 EDI: f8c0f0c4 EBP: e2fd9d50 ESP: e2fd9d2c DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process qv4l2 (pid: 15413, ti=e2fd9000 task=ebe44000 task.ti=e2fd9000) Stack: f8c0c6ae e2ff2a00 00000d00 e2fd9ec4 ebc4e000 e2fd9d5c f8c0c448 00000000 f899c12a e2fd9d5c f899c154 e2fd9d68 e2fd9d80 c0560185 e2fd9d88 f8f3e1d8 f8f3e1dc ebc4e034 f8f3e18c e2fd9ec4 00000000 e2fd9d90 f899c286 c008561c Call Trace: [<f8c0c6ae>] ? chip_command+0x266/0x4b6 [tvaudio] [<f8c0c448>] ? chip_command+0x0/0x4b6 [tvaudio] [<f899c12a>] ? i2c_cmd+0x0/0x2f [i2c_core] [<f899c154>] ? i2c_cmd+0x2a/0x2f [i2c_core] [<c0560185>] ? device_for_each_child+0x21/0x49 [<f899c286>] ? i2c_clients_command+0x1c/0x1e [i2c_core] [<f8f283d8>] ? bttv_call_i2c_clients+0x14/0x16 [bttv] [<f8f23601>] ? bttv_s_ctrl+0x1bc/0x313 [bttv] [<f8f23445>] ? bttv_s_ctrl+0x0/0x313 [bttv] [<f8b6096d>] ? __video_do_ioctl+0x1f84/0x3726 [videodev] [<c05abb4e>] ? sock_aio_write+0x100/0x10d [<c041b23e>] ? kmap_atomic_prot+0x1dd/0x1df [<c043a0c9>] ? enqueue_hrtimer+0xc2/0xcd [<c04f4fa4>] ? copy_from_user+0x39/0x121 [<f8b622b9>] ? __video_ioctl2+0x1aa/0x24a [videodev] [<c04054fd>] ? do_notify_resume+0x768/0x795 [<c043c0f7>] ? getnstimeofday+0x34/0xd1 [<c0437b77>] ? autoremove_wake_function+0x0/0x33 [<f8b62368>] ? video_ioctl2+0xf/0x13 [videodev] [<c048c6f0>] ? vfs_ioctl+0x50/0x69 [<c048c942>] ? do_vfs_ioctl+0x239/0x24c [<c048c995>] ? sys_ioctl+0x40/0x5b [<c0405bf2>] ? syscall_call+0x7/0xb [<c0620000>] ? cpuid4_cache_sysfs_exit+0x3d/0x69 ======================= Code: Bad EIP value.

This patch checks for volume, bass, treble, set mode and get mode callbacks before actually enabling the code that would use them. Instead of aborting the driver for load, this patch will allow it to load with a reduced number of functionatities. This prevents OOPS if some board entry is missing a needed callback.

2008-11-14V4L/DVB (9617): tvtime: remove generic_checkmode callbackMauro Carvalho Chehab
generic_checkmode() were called, via a callback, for some tvaudio chips. There's just one callback code used on all those boards. So, it makes no sense on keeping this as a callback. Since there were some OOPS reported on tvaudio on kerneloops.org, this patch removes this callback, adding the code at the only place were it is called: inside chip_tread. A flag were added to indicate the need for a kernel thread to set stereo mode on cards that needs it. Using this more direct approach simplifies the code, making it more robust against human errors.

2008-11-13dm: avoid destroying table in dm_any_congestedChandra Seetharaman
dm_any_congested() just checks for the DMF_BLOCK_IO and has no code to make sure that suspend waits for dm_any_congested() to complete. This patch adds such a check. Without it, a race can occur with dm_table_put() attempting to destroying the table in the wrong thread, the one running dm_any_congested() which is meant to be quick and return immediately. Two examples of problems: 1. Sleeping functions called from congested code, the caller of which holds a spin lock. 2. An ABBA deadlock between pdflush and multipathd. The two locks in contention are inode lock and kernel lock.

2008-11-13USB: gadget: cdc-acm deadlock fixDavid Brownell
This fixes a deadlock appearing with some USB peripheral drivers when running CDC ACM gadget code. The newish (2.6.27) CDC ACM event notification mechanism sends messages (IN to the host) which are short enough to fit in most FIFOs. That means that with some peripheral controller drivers (evidently not the ones used to verify the notification code!!) the completion callback can be issued before queue() returns. The deadlock would come because the completion callback and the event-issuing code shared a spinlock. Fix is trivial: drop that lock while queueing the message.

2008-11-13USB: EHCI: fix handling of dead controllersAlan Stern
This patch (as1165) makes a few small changes in the logic used by ehci-hcd when it encounters a controller error: Instead of printing out the masked status, it prints the original status as read directly from the hardware. It doesn't check for the STS_HALT status bit before taking action. The mere fact that the STS_FATAL bit is set means that something bad has happened and the controller needs to be reset. With the old code this test could never succeed because the STS_HALT bit was masked out from the status. I anticipate that this will prevent the occasional "irq X: nobody cared" problem people encounter when their EHCI controllers die.

Worse, this deadlocks keventd and this takes whole box down. I'm going to fix this properly later, but let's unbreak the driver quickly for non-composite devices at least.

Until there is a checkbox where the user *must* select atleast one item, and may select multiple entries I don't make it selectable anymore. Having a driver which can't be used under any circumstances is broken anyway and I've seen distros shipping it that way.

Fixes co-working issue of usb serial device with usb/net devices while oter endpoints are free and can be used.This patch implements the policy that if endpoint resources are available then different BULK request goes to different endpoint otherwise they are multiplexed to one reserved endpoint as currently done. Switch statement case is reordered in musb_giveback() to take care of bulk request both in multiplex scenario and otherwise. NAK limit scheme has to be added for multiplexed BULK request scenario to avoid endpoint starvation due to usb/net devices.
