2014-09-21[media] em28xx: fix VBI handling logicMauro Carvalho Chehab1-1/+1
When both VBI and video are streaming, and video stream is stopped, a subsequent trial to restart it will fail, because S_FMT will return -EBUSY. That prevents applications like zvbi to work properly. Please notice that, while this fix it fully for zvbi, the best is to get rid of streaming_users and res_get logic as a hole. However, this single-line patch is better to be merged at -stable. Cc: [email protected] Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2014-09-21[media] DocBook media: improve the poll() documentationHans Verkuil1-4/+19
The poll documentation was incomplete: document how events (POLLPRI) are handled and fix the documentation of what poll does for display devices and streaming I/O.

2014-09-21[media] vb2: fix VBI/poll regressionHans Verkuil2-3/+18
The recent conversion of saa7134 to vb2 unconvered a poll() bug that broke the teletext applications alevt and mtt. These applications expect that calling poll() without having called VIDIOC_STREAMON will cause poll() to return POLLERR. That did not happen in vb2. This patch fixes that behavior. It also fixes what should happen when poll() is called when STREAMON is called but no buffers have been queued. In that case poll() will also return POLLERR, but only for capture queues since output queues will always return POLLOUT anyway in that situation. This brings the vb2 behavior in line with the old videobuf behavior.

2014-09-21[media] cx2341x: fix kernel oopsHans Verkuil1-0/+1
The v4l2_ctrl_config struct must be zeroed before passing it to v4l2_ctrl_new_custom(). This was always wrong, but with the recent v4l2-ctrls.c changes this is now much more likely to lead to a kernel bug. This is the only place where this struct wasn't initialized properly.

Commit bd994ddb2a12a3ff48cd549ec82cdceaea9614df (vb2: Fix stream start and buffer completion race) broke the buffer state check in vb2_buffer_done. So accept all three possible states there since I can no longer tell the difference between vb2_buffer_done called from start_streaming or from elsewhere. Instead add a WARN_ON at the end of start_streaming that will check whether any buffers were added to the done list, since that implies that the wrong state was used as well.

Add comments before those WARN_ON calls that refer to the videobuf2-core.h header that explains what drivers are supposed to do in these situations. That should help point developers in the right direction if they see these warnings.

2014-09-19USB: storage: Add quirks for Entrega/Xircom USB to SCSI convertersMark1-0/+20
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

2014-09-19USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapterMark1-0/+6
Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

2014-09-19USB: EHCI: unlink QHs even after the controller has stoppedAlan Stern1-2/+0
Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.

fix several issues in sparc BPF JIT compiler. ldx/stx related: . classic BPF instructions that access mem[] slots were not setting SEEN_MEM flag, so stack wasn't allocated. Fix that by advertising correct flags . LDX/STX instructions were missing SEEN_XREG, so register value could have leaked to user space. Fix it. . since stack for mem[] slots is allocated with 'sub %sp' instead of 'save %sp', use %sp as base register instead of %fp. . ldx mem[0] means first slot in classic BPF which should have -4 offset instead of 0. . sparc64 needs 2047 stack bias as per ABI to access stack . emit_stmem() was using LD32I macro instead of ST32I SKF_AD_VLAN_TAG* related: . SKF_AD_VLAN_TAG_PRESENT must return 1 or 0 instead of '> 0' or 0 as per classic BPF de facto standard .
