From 8c9ce606a60e4a0cb447bdc082ce383b96b227b4 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Fri, 25 May 2012 16:11:09 -0400 Subject: xen/blkback: Copy id field when doing BLKIF_DISCARD. We weren't copying the id field so when we sent the response back to the frontend (especially with a 64-bit host and 32-bit guest), we ended up using a random value. This lead to the frontend crashing as it would try to pass to __blk_end_request_all a NULL 'struct request' (b/c it would use the 'id' to find the proper 'struct request' in its shadow array) and end up crashing: BUG: unable to handle kernel NULL pointer dereference at 000000e4 IP: [] __blk_end_request_all+0xc/0x40 .. snip.. EIP is at __blk_end_request_all+0xc/0x40 .. snip.. [] blkif_interrupt+0x172/0x330 [xen_blkfront] This fixes the bug by passing in the proper id for the response.

This means that we can up calling iio_dev_release after iio_device_free which will lead to a use after free. As the general rule the struct containing the device should always be freed in the release callback. This is what this patch does, it moves freeing the iio device struct as well as releasing the idr reference to the release callback. To ensure that the device is not freed before calling iio_device_free the device_unregister call in iio_device_unregister is broken apart. iio_device_unregister will now only call device_del to remove the device from the system and iio_device_free will call put_device to drop the reference we obtained in iio_devce_alloc. We also have to take care that calling iio_device_free without having called iio_device_register still works (i.e. this can happen if something failed during device initialization). For this to work properly two minor changes were necessary: channel_attr_list needs to be initialized in iio_device_alloc and we have to check whether the chrdev has been registered before releasing it in iio_device_release. This change also brings iio_device_unregister and iio_device_free more in sync with iio_device_register and iio_device_alloc which call device_add and device_initialize respectively.

Otherwise, 'mtd_read()' will falsely return -EUCLEAN. Normally, 'mtd->bitflip_threshold' is initialized when the MTD is added. However, this is too late for NAND MTDs, as 'scan_bbt()' is invoked prior the existing initialization of 'mtd->bitflip_threshold'. This is a problem since 'scan_bbt()' calls 'mtd_read()', in the case of a flash-based bad block table. It resulted in a falsely reported bitflips indication during BBT read, which lead to constant scrubbing of the flash BBT blocks. Initialize 'mtd->bitflip_threshold' to its default value (if not already set by the driver), prior to invocation of 'scan_bbt()'.

This check was added by commit b5257c952dda24df7078c74b7b811b44c6e49206 as part of workaround for hardware issue. Commit 2e42e4747ea72943c21551d8a206b51a9893b1e0 that replaced compare_ether_addr with ether_addr_equal relieved that this compare to be inverse of what it should be. Compare was added as response to hardware bug, where bssid-list does not contain BSSID and other information of currently connected AP (spec insists that device must provide this information in the list when connected). Lack bssid-data on current connection then causes WARN_ON somewhere in cfg80211. Workaround was to check if bssid-list returns current bssid and if it does not, manually construct bssid information in other ways. And this workaround worked, with inverse check. Which must mean that when hardware is experiencing the problem, it's actually returning empty bssid-list and this check didn't make any difference for workaround. However inverse check causes workaround be activated when bssid-list returns only entry, currently connected BSSID. That does not cause problems in itself, just slightly more inaccurate information in scan-list. Cc: Joe Perches Cc: David S. Miller Signed-off-by: Jussi Kivilinna Signed-off-by: John W.

Part of the ring structure is the 'id' field which is under control of the frontend. The frontend stamps it with "some" value (this some in this implementation being a value less than BLK_RING_SIZE), and when it gets a response expects said value to be in the response structure. We have a check for the id field when spolling new requests but not when de-spolling responses. We also add an extra check in add_id_to_freelist to make sure that the 'struct request' was not NULL - as we cannot pass a NULL to __blk_end_request_all, otherwise that crashes (and all the operations that the response is dealing with end up with __blk_end_request_all). Lastly we also print the name of the operation that failed.

This is done with the pl330_lock held. Then, it iterates through the req_done list, calling the callback for each of the requests that are done. The problem is that the driver releases the lock before calling the callback for each of the callbacks. pl330_submit_req() running in another processor can then acquire the lock and insert another request in one of the thrd->req that hasn't been processed yet, replacing the pointer to pl330_req there. When the callback returns in pl330_update() and the next rqdone is popped from the list, it dereferences the pl330_req pointer to the just scheduled pl330_req, instead of the one that has finished, calling pl330 with the wrong r. This patch fixes this by storing the pointer to pl330_req directly in the list.

This clock is based off of the SYSTIME registers along with the TIMINCA registers. The TIMINCA register determines the increment to be added to the SYSTIME registers every DMA clock tick. This register needs to be reconfigured whenever the link-speed changes. However, the value calculated stays the same when link is down and when link is up. Misconfiguration can occur if the link status changes due to a reset, which causes the TIMINCA register to be reset. This reset puts the device in an unstable state where the SYSTIME registers stop incrementing and the PTP protocol does not function. The solution is to double check the TIMINCA value and always reset the value if the register is zero. This prevents a misconfiguration bug that halts the PHC.

This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff.

It's observed that WPS handshake fails with some 11n AP. The reason for the failure is that the eapol packet is sent via 11n frame aggregation. The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission.

While handling events, we perform skb_pull(skb, 4) to remove event header. Corresponding skb_push() call is missing while submitting the buffer. 2) For PCIe interface, event skb is passed with event header. Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH will not work for PCIe, as they assume event skb points to event body.

Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards are very prone to NETDEV watchdog problems without this change. See https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance. I don't know why it *works*. It's depressingly effective though. For the record: - the problem may go along IOMMU (AMD-Vi) errors but it really looks like a red herring. - the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide, the chipset now fetches several Rx descriptors at a time. - long ago the driver ignored the RX_MULTI_EN bit. e542a2269f232d61270ceddd42b73a4348dee2bb changed the RxConfig settings. Whatever the problem it's now labeled a regression. - Realtek's own driver can identify two different 8168evl devices (CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only sees one. It sucks.

They report bogus sizes, in some cases becoming unusable as a result. The bugs were triggered by commit 09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI & usb-storage: add flags for VPD pages and REPORT LUNS), which caused usb-storage to stop overriding the SCSI level reported by devices. By default, the sd driver will try READ CAPACITY(16) first for any device whose level is above SCSI_SPC_2. It seems likely that any device large enough to require the use of READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ CAPACITY(10) commands properly. Indeed, I don't know of any devices that don't handle READ CAPACITY(10) properly. Therefore this patch (as1559) adds a new flag telling the sd driver to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag for every USB mass-storage device. If a device really is larger than 2 TB, sd will fall back to READ CAPACITY(16) just as it used to. This fixes Bugzilla #43391. Signed-off-by: Alan Stern Acked-by: Hans de Goede CC: "James E.J.

This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

The cause turns out to be that when the AP station is added but we don't associate, the IWL_STA_UCODE_INPROGRESS is set but never cleared. This then causes iwl_restore_stations() to attempt to resend it because it uses the flag internally and uploads even if it didn't set it itself. To fix this issue and not upload the station again when it has already been removed by mac80211, clear the flag after adding it in case we add it only for association.

The code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific chipsets to 1 CRTC based on (pci_device & 0x0ff0). The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing memory corruption because there's actually 2 CRTCs.. This switches fbcon to use the CRTC count directly from the mode_config structure, which will also fix the same issue on Kepler boards which have 4 CRTCs.

But mmc_sd_num_wr_blocks() function which sends the ACMD22 calculates the data timeout value from csd.tacc_ns and csd.tacc_clks parameters which will be 0 for block addressed (>2GB cards) SD card. This would result in timeout_ns and timeout_clks being 0 in the mmc_request passed to host driver. This means host controller would program its data timeout timer value with 0 which could result in DATA TIMEOUT errors from controller. To fix this issue, mmc_sd_num_wr_blocks() should instead just call the mmc_set_data_timeout() to calculate the data timeout value. mmc_set_data_timeout() function ensures that non zero timeout value is set even for block addressed SD cards.

Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit. - SDIO does not support this feature. - SD card only. Looks it is not suitable to always enable Auto CMD12 in host controller driver. Considered that the commit is not mature enough, so ask to revert it first.

This was resulting in the FCoE DDP logic having issues since it thought the frame still had data in it due to the padding.

This patch fixes the regression that caused this issue in the first place. acpi_idle_suspend flag is essential on some x86 systems to prevent the cpus from going to deeper C-states when suspend is triggered ( commit b04e7bdb984 ) So reverting the commit 3439a8da is essential. By default, irqs are disabled in cpu_idle arch specific call and re-enabled in idle state return path . During suspend, the acpi_idle_suspend flag is set, which prevents the cpus from going to deeper idle states, it is essential to enabling the irqs in this return path too. To address the suspend issue, we were not re-enabling the interrupts while returning from acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set. and this caused suspend failure. In addition to the above, to improve the readability of the code, return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend return path. Implying that the system is currently busy when suspend is in progress, which prevents the cpus from entering deeper C-states.

The current code assumes variablely sized VM page tables so SI may end up with part of each page table overlapping with other memory which could end up being interpreted by the VM hw as garbage. Change the code to better accomodate SI. Allocate enough space for at least 2 full page tables and always set last_pfn to max_pfn on SI so each VM is backed by a full page table. This limits us to only 2 VMs active at any given time on SI. This will be rectified and the code can be reunified once we move to two level page tables.

Users currently must disable jumbos when receive hashing offload is enabled, or vice versa, because of this incompatibility. Since testing has shown that IP payload checksum does not provide any real benefit, just remove it so that there is no longer a choice between jumbos or receive hashing offload but not both as done in other Intel GbE drivers (e.g. e1000, igb).

The value returned by "mddev_check_plug" is only valid until the next 'schedule' as that will unplug things. This could happen at any call to mempool_alloc. So just calling mddev_check_plug at the start doesn't really make sense. So call it just before, or just after, queuing things for the thread. As the action that happens at unplug is to wake the thread, this makes lots of sense. If we cannot add a plug (which requires a small GFP_ATOMIC alloc) we wake thread immediately. RAID5 is a bit different. Requests are queued for the thread and the thread is woken by release_stripe. So we don't need to wake the thread on failure. However the thread doesn't perform certain actions when there is any active plug, so it is important to install a plug before waking the thread. So for RAID5 we install the plug *before* queuing the request and waking the thread. Without this patch it is possible for raid1 or raid10 to queue a request without then waking the thread, resulting in the array locking up. Also change raid10 to only flush_pending_write when there are not active plugs, just like raid1. This patch is suitable for 3.0 or later. I plan to submit it to -stable, but I'll like to let it spend a few weeks in mainline first to be sure it is completely safe.

Thus such a mode would be picked up as the preferred mode although it's no native resolution.

Unfortunately we can't do this as early as readon does (i.e. as the first thing we do when initializing the hw) because our fb/mmio space region moves around on a per-gen basis. So I've had to move it below the gtt initialization, but that seems to work, too. The important thing is that we do this before we set up the gtt wc mapping. Now an altogether different question is why people compile their kernels with vesafb enabled, but I guess making things just work isn't bad per se ... v2: - s/radeondrmfb/inteldrmfb/ - fix up error handling v3: Kill #ifdef X86, this is Intel after all. Noticed by Ben Widawsky. v4: Jani Nikula complained about the pointless bool primary initialization. v5: Don't oops if we can't allocate, noticed by Chris Wilson. v6: Resolve conflicts with agp rework and fixup whitespace. This is commit e188719a2891f01b3100d in drm-next. Backport to 3.5 -fixes queue requested by Dave Airlie - due to grub using vesa on fedora their initrd seems to load vesafb before loading the real kms driver. So tons more people actually experience a dead-slow gpu. Hence also the Cc: stable.

The checksums mean userland spots this corruption immediately so there's no risk of acting on incorrect data. No corruption exists from the kernel's point of view, and thin_check passes after pool shutdown. I believe this is to do with shared blocks at the first level of the {device, mapping} btree. Prior to the metadata-snap support no sharing at this level was possible, so this patch is only required after commit cc8394d86f045b86ff303d3c9e4ce47d97148951 ("dm thin: provide userspace access to pool metadata").

However, the "del_timer(&fd_timeout)" was lost in the process, and any previous pending timeouts would stay active when we then re-queued the timeout. This resulted in the floppy probe sequence having a (stale) 20s timeout rather than the intended 3s timeout, and thus made booting with the floppy driver (but no actual floppy controller) take much longer than it should. Of course, there's little reason for most people to compile the floppy driver into the kernel at all, which is why most people never noticed. Canceling the delayed work where we used to do the del_timer() fixes the issue, and makes the floppy probing use the proper new timeout instead. The three second timeout is still very wasteful, but better than the 20s one.

If a message arrives while its endpoint is being removed (because the rpmsg driver was removed, or a recovery of a remote processor has kicked in) we must ensure atomicity, i.e.: - Either the ept is removed before it is found or - The ept is found but will not be freed until the callback returns This is achieved by maintaining a per-ept reference count, which, when drops to zero, will trigger deallocation of the ept. With this in hand, it is now forbidden to directly deallocate epts once they have been added to the endpoints idr.

I audited both and this seems safe in practice but this is not guaranteed by the API. Additionally, a spurious interrupt might in theory make virtqueue_get_buf run in parallel with virtqueue_add_buf, which is racy. While we might try to protect against spurious callbacks it's easier to fix the driver: balloon seems to be the only one (mis)using the API like this, so let's just fix balloon.

This begins the migration of the PFC core to the pinctrl subsystem. Initial support is very basic, with the bulk of the implementation simply being nopped out in such a way to allow registration with the pinctrl core to succeed. The gpio chip driver is stripped down considerably now relying purely on pinctrl API calls to manage the bulk of its operations. This provides a basis for further PFC refactoring, including decoupling pin functions from the GPIO API, establishing pin groups, and so forth. These will all be dealt with incrementally so as to introduce as few growing and migratory pains to tree-wide PFC pinmux users today. When the interfaces have been well established and in-tree users have been migrated off of the legacy interfaces it will be possible to strip down the core considerably, leading to eventual drivers/pinctrl rehoming.
