commit ce36d9ab upstream. When we SMB3 mounted with mapchars (to allow reserved characters : \ / > < * ? via the Unicode Windows to POSIX remap range) empty paths (eg when we open "" to query the root of the SMB3 directory on mount) were not null terminated so we sent garbarge as a path name on empty paths which caused SMB2/SMB2.1/SMB3 mounts to fail when mapchars was specified. mapchars is particularly important since Unix Extensions for SMB3 are not supported (yet) Signed-off-by:

commit 2fc68eb1 upstream. Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value). So far it was (most probably) affecting monitor mode users only, but the following recent commit made it noticeable for quite everybody: commit 3afc2167 Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Tue Mar 4 16:50:13 2014 +0200 cfg80211/mac80211: ignore signal if the frame was heard on wrong channel Reported-by:

commit c021f241 upstream. Fix a parser-bug in the omap2 muxing code where muxtable-entries will be wrongly selected if the requested muxname is a *prefix* of their m0-entry and they have a matching mN-entry. Fix by additionally checking that the length of the m0_entry is equal. For example muxing of "dss_data2.dss_data2" on omap32xx will fail because the prefix "dss_data2" will match the mux-entries "dss_data2" as well as "dss_data20", with the suffix "dss_data2" matching m0 (for dss_data2) and m4 (for dss_data20). Thus both are recognized as signal path candidates: Relevant muxentries from mux34xx.c: _OMAP3_MUXENTRY(DSS_DATA20, 90, "dss_data20", NULL, "mcspi3_somi", "dss_data2", "gpio_90", NULL, NULL, "safe_mode"), _OMAP3_MUXENTRY(DSS_DATA2, 72, "dss_data2", NULL, NULL, NULL, "gpio_72", NULL, NULL, "safe_mode"), This will result in a failure to mux the pin at all: _omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2 Patch should apply to linus' latest master down to rather old linux-2.6 trees.

commit c0214f98 upstream. All devices supported by ina2xx are bidirectional and report the measured shunt voltage and power values as a signed 16 bit, but the current driver implementation caches all registers as u16, leading to an incorrect sign extension when reporting to userspace in ina2xx_get_value(). This patch fixes the problem by casting the signed registers to s16. Tested on an INA219. Signed-off-by:

commit 9638556a upstream. The following check in rbd_img_obj_request_submit() rbd_dev->parent_overlap <= obj_request->img_offset allows the fall through to the non-layered write case even if both parent_overlap and obj_request->img_offset belong to the same RADOS object. This leads to data corruption, because the area to the left of parent_overlap ends up unconditionally zero-filled instead of being populated with parent data. Suppose we want to write 1M to offset 6M of image bar, which is a clone of foo@snap; object_size is 4M, parent_overlap is 5M: rbd_data.<id>.0000000000000001 ---------------------|----------------------|------------ | should be copyup'ed | should be zeroed out | write ... ---------------------|----------------------|------------ 4M 5M 6M parent_overlap obj_request->img_offset 4..5M should be copyup'ed from foo, yet it is zero-filled, just like 5..6M is. Given that the only striping mode kernel client currently supports is chunking (i.e. stripe_unit == object_size, stripe_count == 1), round parent_overlap up to the next object boundary for the purposes of the overlap check.

commit 0f2d5be7 upstream. Each image request contains a reference count, but to date it has not actually been used. (I think this was just an oversight.) A recent report involving rbd failing an assertion shed light on why and where we need to use these reference counts. Every OSD request associated with an object request uses rbd_osd_req_callback() as its callback function. That function will call a helper function (dependent on the type of OSD request) that will set the object request's "done" flag if the object request if appropriate. If that "done" flag is set, the object request is passed to rbd_obj_request_complete(). In rbd_obj_request_complete(), requests are processed in sequential order. So if an object request completes before one of its predecessors in the image request, the completion is deferred. Otherwise, if it's a completing object's "turn" to be completed, it is passed to rbd_img_obj_end_request(), which records the result of the operation, accumulates transferred bytes, and so on. Next, the successor to this request is checked and if it is marked "done", (deferred) completion processing is performed on that request, and so on. If the last object request in an image request is completed, rbd_img_request_complete() is called, which (typically) destroys the image request. There is a race here, however. The instant an object request is marked "done" it can be provided (by a thread handling completion of one of its predecessor operations) to rbd_img_obj_end_request(), which (for the last request) can then lead to the image request getting torn down. And this can happen *before* that object has itself entered rbd_img_obj_end_request(). As a result, once it *does* enter that function, the image request (and even the object request itself) may have been freed and become invalid. All that's necessary to avoid this is to properly count references to the image requests. We tear down an image request's object requests all at once--only when the entire image request has completed. So there's no need for an image request to count references for its object requests. However, we don't want an image request to go away until the last of its object requests has passed through rbd_img_obj_callback(). In other words, we don't want rbd_img_request_complete() to necessarily result in the image request being destroyed, because it may get called before we've finished processing on all of its object requests. So the fix is to add a reference to an image request for each of its object requests. The reference can be viewed as representing an object request that has not yet finished its call to rbd_img_obj_callback(). That is emphasized by getting the reference right after assigning that as the image object's callback function. The corresponding release of that reference is done at the end of rbd_img_obj_callback(), which every image object request passes through exactly once. Signed-off-by:

commit 09869de5 upstream. DM thinp already checks whether the discard_granularity of the data device is a factor of the thin-pool block size. But when using the dm-thin-pool's discard passdown support, DM thinp was not selecting the max of the underlying data device's discard_granularity and the thin-pool's block size. Update set_discard_limits() to set discard_granularity to the max of these values. This enables blkdev_issue_discard() to properly align the discards that are sent to the DM thin device on a full block boundary. As such each discard will now cover an entire DM thin-pool block and the block will be reclaimed. Reported-by:

commit e694788d upstream. The conn->link_key variable tracks the type of link key in use. It is set whenever we respond to a link key request as well as when we get a link key notification event. These two events do not however always guarantee that encryption is enabled: getting a link key request and responding to it may only mean that the remote side has requested authentication but not encryption. On the other hand, the encrypt change event is a certain guarantee that encryption is enabled. The real encryption state is already tracked in the conn->link_mode variable through the HCI_LM_ENCRYPT bit. This patch fixes a check for encryption in the hci_conn_auth function to use the proper conn->link_mode value and thereby eliminates the chance of a false positive result. Signed-off-by:

commit f306e8c3 upstream. fixes: commit 62116e51 mtd: nand: omap2: Support for hardware BCH error correction. In omap_elm_correct_data(), if bitflip_count in an erased-page is within the correctable limit (< ecc.strength), then it is not indicated back to the caller ecc->read_page(). This mis-guides upper layers like MTD and UBIFS layer to assume erased-page as perfectly clean and use it for writing even if actual bitflip_count was dangerously high (bitflip_count > mtd->bitflip_threshold). This patch fixes this above issue, by returning 'stats' to caller ecc->read_page() under all scenarios. Reported-by:

This behavior was introduced in commit 837a6ba4 "mtd: nand: subpage write support for hardware based ECC schemes".

commit 616a8394 upstream. As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5f, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit.

commit d6236f6d upstream. The system suspend flow as following: 1, Freeze all user processes and kenrel threads. 2, Try to suspend all devices. 2.1, If pci device is in RPM suspended state, then pci driver will try to resume it to RPM active state in the prepare stage. 2.2, xhci_resume function calls usb_hcd_resume_root_hub to queue two workqueue items to resume usb2&usb3 roothub devices. 2.3, Call suspend callbacks of devices. 2.3.1, All suspend callbacks of all hcd's children, including roothub devices are called. 2.3.2, Finally, hcd_pci_suspend callback is called. Due to workqueue threads were already frozen in step 1, the workqueue items can't be scheduled, and the roothub devices can't be resumed in this flow. The HCD_FLAG_WAKEUP_PENDING flag which is set in usb_hcd_resume_root_hub won't be cleared. Finally, hcd_pci_suspend will return -EBUSY, and system suspend fails. The reason why this issue doesn't show up very often is due to that choose_wakeup will be called in step 2.3.1. In step 2.3.1, if udev->do_remote_wakeup is not equal to device_may_wakeup(&udev->dev), then udev will resume to RPM active for changing the wakeup settings. This has been a lucky hit which hides this issue. For some special xHCI controllers which have no USB2 port, then roothub will not match hub driver due to probe failed. Then its do_remote_wakeup will be set to zero, and we won't be as lucky. xhci driver doesn't need to resume roothub devices everytime like in the above case. It's only needed when there are pending event TRBs. This patch should be back-ported to kernels as old as 3.2, that contains the commit f69e3120 "USB: XHCI: resume root hubs when the controller resumes" Signed-off-by:

commit 379cfdac upstream. In order to prevent the saved cmdline cache from being filled when tracing is not active, the comms are only recorded after a trace event is recorded. The problem is, a comm can fail to be recorded if the trace_cmdline_lock is held. That lock is taken via a trylock to allow it to happen from any context (including NMI). If the lock fails to be taken, the comm is skipped. No big deal, as we will try again later. But! Because of the code that was added to only record after an event, we may not try again later as the recording is made as a oneshot per event per CPU. Only disable the recording of the comm if the comm is actually recorded. Fixes: 7ffbd48d "tracing: Cache comms only after an event occurred" Signed-off-by:
