Can result in a double free if the trigger is changed. * Fix a buglet with xilinx-xadc concerning setup of the address for an aux channel. * At91 adc driver could sometimes get a touchscreen reading rather than the intended adc channel. This is fixed by using the channel data register instead. * Fix some ST magnetometer gain values that differ in production parts from the prerelease ones used for driver development.
2014-09-19USB: storage: Add quirks for Entrega/Xircom USB to SCSI convertersMark
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 adapterMark
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 Stern
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: .

2014-09-19Revert "PCI: Make sure bus number resources stay within their parents bounds"Bjorn Helgaas
This reverts commit 1820ffdccb9b ("PCI: Make sure bus number resources stay within their parents bounds") because it breaks some systems with LSI Logic FC949ES Fibre Channel Adapters, apparently by exposing a defect in those adapters. Dirk tested a Tyan VX50 (B4985) with this device that worked like this prior to 1820ffdccb9b: bus: [bus 00-7f] on node 0 link 1 ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-07]) pci 0000:00:0e.0: PCI bridge to [bus 0a] pci_bus 0000:0a: busn_res: can not insert [bus 0a] under [bus 00-07] (conflicts with (null) [bus 00-07]) pci 0000:0a:00.0: [1000:0646] type 00 class 0x0c0400 (FC adapter) Note that the root bridge [bus 00-07] aperture is wrong; this is a BIOS defect in the PCI0 _CRS method. But prior to 1820ffdccb9b, we didn't enforce that aperture, and the FC adapter worked fine at 0a:00.0. After 1820ffdccb9b, we notice that 00:0e.0's aperture is not contained in the root bridge's aperture, so we reconfigure it so it *is* contained: pci 0000:00:0e.0: bridge configuration invalid ([bus 0a-0a]), reconfiguring pci 0000:00:0e.0: PCI bridge to [bus 06-07] This effectively moves the FC device from 0a:00.0 to 07:00.0, which should be legal. But when we enumerate bus 06, the FC device doesn't respond, so we don't find anything. This is probably a defect in the FC device. Possible fixes (due to Yinghai): 1) Add a quirk to fix the _CRS information based on what amd_bus.c read from the hardware 2) Reset the FC device after we change its bus number 3) Revert 1820ffdccb9b Fix 1 would be relatively easy, but it does sweep the LSI FC issue under the rug. We might want to reconfigure bus numbers in the future for some other reason, e.g., hotplug, and then we could trip over this again. For that reason, I like fix 2, but we don't know whether it actually works, and we don't have a patch for it yet. This revert is fix 3, which also sweeps the LSI FC issue under the rug.

2014-09-19Revert "PCI: Don't scan random busses in pci_scan_bridge()"Bjorn Helgaas
This reverts commit fc1b253141b3 ("PCI: Don't scan random busses in pci_scan_bridge()") because it breaks CardBus on some machines. David tested a Dell Latitude D505 that worked like this prior to fc1b253141b3: pci 0000:00:1e.0: PCI bridge to [bus 01] pci 0000:01:01.0: CardBus bridge to [bus 02-05] Note that the 01:01.0 CardBus bridge has a bus number aperture of [bus 02-05], but those buses are all outside the 00:1e.0 PCI bridge bus number aperture, so accesses to buses 02-05 never reach CardBus. This is later patched up by yenta_fixup_parent_bridge(), which changes the subordinate bus number of the 00:1e.0 PCI bridge: pci_bus 0000:01: Raising subordinate bus# of parent bus (#01) from #01 to #05 With fc1b253141b3, pci_scan_bridge() fails immediately when it notices that we can't allocate a valid secondary bus number for the CardBus bridge, and CardBus doesn't work at all: pci 0000:01:01.0: can't allocate child bus 01 from [bus 01] I'd prefer to fix this by integrating the yenta_fixup_parent_bridge() logic into pci_scan_bridge() so we fix the bus number apertures up front. But I don't think we can do that before v3.17, so I'm going to revert this to avoid the problem while we're working on the long-term fix.

2014-09-19IB: ib_umem_release() should decrement mm->pinned_vm from ib_umem_getShawn Bohrer
In debugging an application that receives -ENOMEM from ib_reg_mr(), I found that ib_umem_get() can fail because the pinned_vm count has wrapped causing it to always be larger than the lock limit even with RLIMIT_MEMLOCK set to RLIM_INFINITY. The wrapping of pinned_vm occurs because the process that calls ib_reg_mr() will have its mm->pinned_vm count incremented. Later a different process with a different mm_struct than the one that allocated the ib_umem struct ends up releasing it which results in decrementing the new processes mm->pinned_vm count past zero and wrapping. I'm not entirely sure what circumstances cause a different process to release the ib_umem than the one that allocated it but the kernel stack trace of the freeing process from my situation looks like the following: Call Trace: [<ffffffff814d64b1>] dump_stack+0x19/0x1b [<ffffffffa0b522a5>] ib_umem_release+0x1f5/0x200 [ib_core] [<ffffffffa0b90681>] mlx4_ib_destroy_qp+0x241/0x440 [mlx4_ib] [<ffffffffa0b4d93c>] ib_destroy_qp+0x12c/0x170 [ib_core] [<ffffffffa0cc7129>] ib_uverbs_close+0x259/0x4e0 [ib_uverbs] [<ffffffff81141cba>] __fput+0xba/0x240 [<ffffffff81141e4e>] ____fput+0xe/0x10 [<ffffffff81060894>] task_work_run+0xc4/0xe0 [<ffffffff810029e5>] do_notify_resume+0x95/0xa0 [<ffffffff814e3dd0>] int_signal+0x12/0x17 The following patch fixes the issue by storing the pid struct of the process that calls ib_umem_get() so that ib_umem_release and/or ib_umem_account() can properly decrement the pinned_vm count of the correct mm_struct.

2014-09-19[SCSI] fix for bidi use after freeDaniel Gryniewicz
When ending a bi-directionional SCSI request, blk_finish_request() cleans up and frees the request, but scsi_release_bidi_buffers() tries to indirect through the request to find it's data buffers. This causes a panic due to a null pointer dereference. Move the call to scsi_release_bidi_buffers() before the call to blk_finish_request().

2014-09-19[SCSI] fix regression that accidentally disabled block-based tcqChristoph Hellwig
The scsi blk-mq support accidentally flipped a conditional, which lead to never enabling block based tcq when using the legacy request path.

2014-09-19[SCSI] libiscsi: fix potential buffer overrun in __iscsi_conn_send_pduMike Christie
This patches fixes a potential buffer overrun in __iscsi_conn_send_pdu. This function is used by iscsi drivers and userspace to send iscsi PDUs/ commands. For login commands, we have a set buffer size. For all other commands we do not support data buffers.

2014-09-19x86/kaslr: Avoid the setup_data area when picking locationKees Cook
The KASLR location-choosing logic needs to avoid the setup_data list memory areas as well. Without this, it would be possible to have the ASLR position stomp on the memory, ultimately causing the boot to fail.
