b6cf878 Christian Borntraeger 20 September 2011, 15:07:29 UTC [S390] kvm: extension capability for new address space layout 598841ca9919d008b520114d8a4378c4ce4e40a1 ([S390] use gmap address spaces for kvm guest images) changed kvm on s390 to use a separate address space for kvm guests. We can now put KVM guests anywhere in the user address mode with a size up to 8PB - as long as the memory is 1MB-aligned. This change was done without KVM extension capability bit. The change was added after 3.0, but we still have a chance to add a feature bit before 3.1 (keeping the releases in a sane state). We use number 71 to avoid collisions with other pending kvm patches as requested by Alexander Graf.

480e592 Christian Borntraeger 20 September 2011, 15:07:28 UTC [S390] kvm: fix address mode switching 598841ca9919d008b520114d8a4378c4ce4e40a1 ([S390] use gmap address spaces for kvm guest images) changed kvm to use a separate address space for kvm guests. This address space was switched in __vcpu_run In some cases (preemption, page fault) there is the possibility that this address space switch is lost. The typical symptom was a huge amount of validity intercepts or random guest addressing exceptions. Fix this by doing the switch in sie_loop and sie_exit and saving the address space in the gmap structure itself. Also use the preempt notifier.

9438fab Jeff Layton 23 August 2011, 11:21:28 UTC cifs: fix possible memory corruption in CIFSFindNext The name_len variable in CIFSFindNext is a signed int that gets set to the resume_name_len in the cifs_search_info. The resume_name_len however is unsigned and for some infolevels is populated directly from a 32 bit value sent by the server. If the server sends a very large value for this, then that value could look negative when converted to a signed int. That would make that value pass the PATH_MAX check later in CIFSFindNext. The name_len would then be used as a length value for a memcpy. It would then be treated as unsigned again, and the memcpy scribbles over a ton of memory. Fix this by making the name_len an unsigned value in CIFSFindNext.

c2d7b49 Andiry Xu 19 September 2011, 23:05:12 UTC USB: xHCI: prevent infinite loop when processing MSE event When a xHC host is unable to handle isochronous transfer in the interval, it reports a Missed Service Error event and skips some tds. Currently xhci driver handles MSE event in the following ways: 1. When encounter a MSE event, set ep->skip flag, update event ring dequeue pointer and return. 2. When encounter the next event on this ep, the driver will run the do-while loop, fetch td from ep's td_list to find the td corresponding to this event. All tds missed are marked as short transfer(-EXDEV). The do-while loop will end in two ways: 1. If the td pointed by the event trb is found; 2. If the ep ring's td_list is empty. However, if a buggy HW reports some unpredicted event (for example, an overrun event following a MSE event while the ep ring is actually not empty), the driver will never find the td, and it will loop until the td_list is empty. Unfortunately, the spinlock is dropped when give back a urb in the do-while loop. During the spinlock released period, the class driver may still submit urbs and add tds to the td_list. This may cause disaster, since the td_list will never be empty and the loop never ends, and the system hangs. To fix this, count the number of TDs on the ep ring before skipping TDs, and quit the loop when skipped that number of tds. This guarantees the do-while loop will end after certain number of cycles, and driver will not be trapped in an infinite loop.

44f4c3e Greg KH 19 September 2011, 23:05:11 UTC USB: xhci: Set change bit when warm reset change is set. Sometimes, when a USB 3.0 device is disconnected, the Intel Panther Point xHCI host controller will report a link state change with the state set to "SS.Inactive". This causes the xHCI host controller to issue a warm port reset, which doesn't finish before the USB core times out while waiting for it to complete. When the warm port reset does complete, and the xHC gives back a port status change event, the xHCI driver kicks khubd. However, it fails to set the bit indicating there is a change event for that port because the logic in xhci-hub.c doesn't check for the warm port reset bit. After that, the warm port status change bit is never cleared by the USB core, and the xHC stops reporting port status change bits. (The xHCI spec says it shouldn't report more port events until all change bits are cleared.) This means any port changes when a new device is connected will never be reported, and the port will seem "dead" until the xHCI driver is unloaded and reloaded, or the computer is rebooted. Fix this by making the xHCI driver set the port change bit when a warm port reset change bit is set. A better solution would be to make the USB core handle warm port reset in differently, merging the current code with the standard port reset code that does an incremental backoff on the timeout, and tries to complete the port reset two more times before giving up. That more complicated fix will be merged next window, and this fix will be backported to stable. This should be backported to kernels as old as 3.0, since that was the first kernel with commit a11496ebf375 ("xHCI: warm reset support").

This is because we clear the need lookup flag before actually instantiating the inode. This will lead the RCU path walk stuff to find a dentry it thinks is valid without a d_inode attached. So instead unhash the dentry when we first start the lookup, and then clear the flag after we've instantiated the dentry so we're garunteed to either try the slow lookup, or have the d_inode set properly.

40b0549 Nicholas Bellinger 16 September 2011, 23:55:47 UTC iscsi-target: Fix sendpage breakage with proper padding+DataDigest iovec offsets This patch fixes a bug in the iscsit_fe_sendpage_sg() transmit codepath that was originally introduced with the v3.1 iscsi-target merge that incorrectly uses hardcoded cmd->iov_data_count values to determine cmd->iov_data[] offsets for extra outgoing padding and DataDigest payload vectors. This code is obviously incorrect for the DataDigest enabled case with sendpage offload, and this fix ensures correct operation for padding + DataDigest, padding only, and DataDigest only cases. The bug was introduced during a pre-merge change in iscsit_fe_sendpage_sg() to natively use struct scatterlist instead of the legacy v3.0 struct se_mem logic.

784eb99 Nicholas Bellinger 16 September 2011, 08:31:28 UTC target: Skip non hex characters for VPD=0x83 NAA IEEE Registered Extended This patch adds target_parse_naa_6h_vendor_specific() to address a bug where the conversion of PRODUCT SERIAL NUMBER to use hex2bin() in target_emulate_evpd_83() was not doing proper isxdigit() checking. This conversion of the vpd_unit_serial configifs attribute is done while generating a VPD=0x83 NAA IEEE Registered Extended DESIGNATOR format's 100 bits of unique VENDOR SPECIFIC IDENTIFIER + VENDOR SPECIFIC IDENTIFIER EXTENSION area. This patch allows vpd_unit_serial (VPD=0x80) and the T10 Vendor ID DESIGNATOR format (VPD=0x83) to continue to use free-form variable length ASCII values, and now skips any non hex characters for fixed length NAA IEEE Registered Extended DESIGNATOR format (VPD=0x83) requring the binary conversion. This was originally reported by Martin after the v3.1-rc1 change to use hex2bin() in commit 11650b859681e03fdbf26277fcfc5f1f62186703 where the use of non hex characters in vpd_unit_serial generated different values than the original v3.0 internal hex -> binary code. This v3.1 change caused a problem with filesystems who write a NAA DESIGNATOR onto it's ondisk metadata, and this patch will (again) change existing values to ensure that non hex characters are not included in the fixed length NAA DESIGNATOR. Note this patch still expects vpd_unit_serial to be set via existing userspace methods of uuid generation, and does not do strict formatting via configfs input. The original bug report and thread can be found here: NAA breakage http://www.spinics.net/lists/target-devel/msg00477.html The v3.1-rc1 formatting of VPD=0x83 w/o this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ebf Vendor Specific Identifier Extension: 0x3092f498ffa820f9 [0x6001405ffde35ebf3092f498ffa820f9] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 The v3.1-final formatting of VPD=0x83 w/ this patch: VPD INQUIRY: Device Identification page Designation descriptor number 1, descriptor length: 20 designator_type: NAA, code_set: Binary associated with the addressed logical unit NAA 6, IEEE Company_id: 0x1405 Vendor Specific Identifier: 0xffde35ec3 Vendor Specific Identifier Extension: 0x924980a82091763 [0x6001405ffde35ec30924980a82091763] Designation descriptor number 2, descriptor length: 56 designator_type: T10 vendor identification, code_set: ASCII associated with the addressed logical unit vendor id: LIO-ORG vendor specific: IBLOCK:ffde35ec-3092-4980-a820-917636ca54f1 (v2: Fix parsing code to dereference + check for string terminator instead of null pointer to ensure a zeroed payload for vpd_unit_serial less than 100 bits of NAA DESIGNATOR VENDOR SPECIFIC area.

58fc73d Christoph Hellwig 26 August 2011, 16:25:38 UTC tcm_fc: Work queue based approach instead of managing own thread and event based mechanism Problem: Changed from wake_up_interruptible -> wake_up_process and wait_event_interruptible-> schedule_timeout_interruptible broke the FCoE target. Earlier approach of wake_up_interruptible was also looking at 'queue_cnt' which is not necessary, because it increment of 'queue_cnt' with wake_up_inetrriptible / waker_up_process introduces race condition. Fix: Instead of fixing the code which used wake_up_process and remove 'queue_cnt', using work_queue based approach is cleaner and acheives same result. As well, work queue based approach has less programming overhead and OS manages threads which processes work queues. This patch is developed by Christoph Hellwig and reviwed+validated by Kiran Patil.

079587b Kiran Patil 26 August 2011, 16:25:25 UTC tcm_fc: Invalidation of DDP context for FCoE target in error conditions Problem: HW DDP context wasn;t invalidated in case of ABORTS, etc... This leads to the problem where memory pages which are used for DDP as user descriptor could get reused for some other purpose (such as to satisfy new memory allocation request either by kernel or user mode threads) and since HW DDP context was not invalidated, HW continue to write to those pages, hence causing memory corruption. Fix: Either on incoming ABORTS or due to exchange time out, allowed the target to cleanup HW DDP context if it was setup for respective ft_cmd. Added new function to perform this cleanup, furthur it can be enhanced for other cleanup activity. Additinal Notes: To avoid calling ddp_done from multiple places, composed the functionality in helper function "ft_invl_hw_context" and it is being called from multiple places. Cleaned up code in function "ft_recv_write_data" w.r.t DDP. Signed-off-by: Kiran Patil <kiran.patil@intel.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org> 16 September 2011, 09:29:27 UTC
bcac364 Roland Dreier 28 August 2011, 04:33:16 UTC target: Fix race between multiple invocations of target_qf_do_work() When work is scheduled with schedule_work(), the work can end up running on multiple CPUs at the same time -- this happens if the work is already running on one CPU and schedule_work() is called on another CPU. This leads to list corruption with target_qf_do_work(), which is roughly doing: spin_lock(...); list_for_each_entry_safe(...) { list_del(...); spin_unlock(...); // do stuff spin_lock(...); } With multiple CPUs running this code, one CPU can end up deleting the list entry that the other CPU is about to work on. Fix this by splicing the list entries onto a local list and then operating on that in the work function. This way, each invocation of target_qf_do_work() operates on its own local list and so multiple invocations don't corrupt each other's list. This also avoids dropping and reacquiring the lock for each list entry.

a7f934d Linus Torvalds 15 September 2011, 20:28:33 UTC asm alternatives: remove incorrect alignment notes On x86-64, they were just wasteful: with the explicitly added (now unnecessary) padding, the size of the alternatives structure was 16 bytes, and an alignment of 8 bytes didn't hurt much. However, it was still silly, since the natural size and alignment for the structure is actually just 12 bytes, 4-byte aligned since commit 59e97e4d6fbc ("x86: Make alternative instruction pointers relative"). So removing the padding, and removing the extra alignment is just a good idea. On x86-32, the alignment of 4 bytes was correct, but was incorrectly hardcoded as 8 bytes in <asm/alternative-asm.h>. That header file had used to be an x86-64 only header file, but various unification efforts have made it be used for x86-32 too (ie the unification of rwlock and rwsem). That in turn caused x86-32 boot failures, because the extra alignment would result in random zero-filled words in the altinstructions section, causing oopses early at boot when doing alternative instruction replacement. So just remove all the alignment noise entirely. It's wrong, and it's unnecessary. The section itself is already properly aligned by the linker scripts, and all additions to the section had better be of the proper 12-byte format, keeping it aligned. So if the align directive were to ever make a difference, that would be an indication of a serious bug to begin with.
