commit 19aeb5a6 upstream. This patch fixes a regression in the patch "GFS2: Remember directory insert point", commit 2b47dad8. The problem had to do with the rename function: The function found space for the new dirent, and remembered that location. But then the old dirent was removed, which often moved the eligible location for the renamed dirent. Putting the new dirent at the saved location caused file system corruption. This patch adds a new "save_loc" variable to struct gfs2_diradd. If 1, the dirent location is saved. If 0, the dirent location is not saved and the buffer_head is released as per previous behavior.

commit fe3d9c4b upstream. A mismatch between FB and LTC's idea of how big a large page is causes issues such as black "holes" in rendering to occur on some boards (those where LTC is configured for 64KiB large pages) when compression is used. Confirmed to fix at least the GK107 MBP. Signed-off-by:

commit 6fbb702e upstream. Linus commit 05c63c2f modified the runtime suspend/resume paths to skip over display-related tasks to avoid locking issues on resume. Unfortunately, this resulted in the display hardware being left in a partially initialised state, preventing subsequent modesets from completing. This commit unifies the (many) suspend/resume paths, bringing back display (and fbcon) handling in the runtime paths. Signed-off-by:

commit 634ffccc upstream. Preparation for some runtime pm fixes. Currently we skip over fbcon suspend/resume in the runtime path, which causes issues on resume if fbcon tries to write to the framebuffer before the BAR subdev has been resumed to restore the BAR1 VM setup. As we might be woken up via a sysfs connector, we are unable to call fb_set_suspend() in the resume path as it could make its way down to a modeset and cause all sorts of locking hilarity. To solve this, we'll just delay the fbcon resume to a workqueue. Signed-off-by:

commit e4a60d13 upstream. There is a race condition when removing glue directory. It can be reproduced in following test: path 1: Add first child device device_add() get_device_parent() /*find parent from glue_dirs.list*/ list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry) if (k->parent == parent_kobj) { kobj = kobject_get(k); break; } .... class_dir_create_and_add() path2: Remove last child device under glue dir device_del() cleanup_device_parent() cleanup_glue_dir() kobject_put(glue_dir); If path2 has been called cleanup_glue_dir(), but not call kobject_put(glue_dir), the glue dir is still in parent's kset list. Meanwhile, path1 find the glue dir from the glue_dirs.list. Path2 may release glue dir before path1 call kobject_get(). So kernel will report the warning and bug_on. This is a "classic" problem we have of a kref in a list that can be found while the last instance could be removed at the same time. This patch reuse gdp_mutex to fix this race condition. The following calltrace is captured in kernel 3.4, but the latest kernel still has this bug. ----------------------------------------------------- <4>[ 3965.441471] WARNING: at ...include/linux/kref.h:41 kobject_get+0x33/0x40() <4>[ 3965.441474] Hardware name: Romley <4>[ 3965.441475] Modules linked in: isd_iop(O) isd_xda(O)... ... <4>[ 3965.441605] Call Trace: <4>[ 3965.441611] [<ffffffff8103717a>] warn_slowpath_common+0x7a/0xb0 <4>[ 3965.441615] [<ffffffff810371c5>] warn_slowpath_null+0x15/0x20 <4>[ 3965.441618] [<ffffffff81215963>] kobject_get+0x33/0x40 <4>[ 3965.441624] [<ffffffff812d1e45>] get_device_parent.isra.11+0x135/0x1f0 <4>[ 3965.441627] [<ffffffff812d22d4>] device_add+0xd4/0x6d0 <4>[ 3965.441631] [<ffffffff812d0dbc>] ? dev_set_name+0x3c/0x40 .... <2>[ 3965.441912] kernel BUG at ..../fs/sysfs/group.c:65! <4>[ 3965.441915] invalid opcode: 0000 [#1] SMP ... <4>[ 3965.686743] [<ffffffff811a677e>] sysfs_create_group+0xe/0x10 <4>[ 3965.686748] [<ffffffff810cfb04>] blk_trace_init_sysfs+0x14/0x20 <4>[ 3965.686753] [<ffffffff811fcabb>] blk_register_queue+0x3b/0x120 <4>[ 3965.686756] [<ffffffff812030bc>] add_disk+0x1cc/0x490 .... ------------------------------------------------------- Signed-off-by:

commit 2a8cdfde upstream. Add new quirk for devices that cannot handle control-line state requests. Note that we currently send these requests to all devices, regardless of whether they claim to support it, but that errors are only logged if support is claimed. Since commit 0943d8ea ("USB: cdc-acm: use tty-port dtr_rts"), which only changed the timings for these requests slightly, this has been reported to cause occasional firmware crashes on Simtec Electronics Entropy Key devices after re-enumeration. Enable the quirk for this device. Reported-by:

Peter Hurley authored
commit 37b16457 upstream. Kernel oops can cause the tty to be unreleaseable (for example, if n_tty_read() crashes while on the read_wait queue). This will cause tty_release() to endlessly loop without sleeping. Use a killable sleep timeout which grows by 2n+1 jiffies over the interval [0, 120 secs.) and then jumps to forever (but still killable). NB: killable just allows for the task to be rewoken manually, not to be terminated. Signed-off-by:

commit 547039ec upstream. uart_get_baud_rate() will return baud == 0 if the max rate is set to the "magic" 38400 rate and the SPD_* flags are also specified. On the first iteration, if the current baud rate is higher than the max, the baud rate is clamped at the max (which in the degenerate case is 38400). On the second iteration, the now-"magic" 38400 baud rate selects the possibly higher alternate baud rate indicated by the SPD_* flag. Since only two loop iterations are performed, the loop is exited, a kernel WARNING is generated and a baud rate of 0 is returned. Reproducible with: setserial /dev/ttyS0 spd_hi base_baud 38400 Only perform the "magic" 38400 -> SPD_* baud transform on the first loop iteration, which prevents the degenerate case from recognizing the clamped baud rate as the "magic" 38400 value.

commit f20531a9 upstream. The USB OTG port does not work since v3.16 on omap platform. This is a regression introduced by the commit eb82a3d8 (phy: omap-usb2: Balance pm_runtime_enable() on probe failure and remove). This because the call to pm_runtime_enable() function is moved after the call to devm_phy_create() function, which has side effect since later in the subsequent calls of devm_phy_create() there is a check with pm_runtime_enabled() to configure few things.

Lars-Peter Clausen authored
commit e1055473 upstream. In older versions of the IIO framework it was possible to pass a completely different set of channels to iio_buffer_register() as the one that is assigned to the IIO device. Commit 959d2952 ("staging:iio: make iio_sw_buffer_preenable much more general.") introduced a restriction that requires that the set of channels that is passed to iio_buffer_register() is a subset of the channels assigned to the IIO device as the IIO core will use the list of channels that is assigned to the device to lookup a channel by scan index in iio_compute_scan_bytes(). If it can not find the channel the function will crash. This patch fixes the issue by making sure that the same set of channels is assigned to the IIO device and passed to iio_buffer_register(). Note that we need to remove the IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE info attributes from the channels since we don't actually want those to be registered.

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

commit 5cc7b047 upstream. There are only 4 CTAR registers (CTAR0 - CTAR3) so we can only use the lower 2 bits of the chip select to select a CTAR register. SPI_PUSHR_CTAS used the lower 3 bits which would result in wrong bit values if the chip selects 4/5 are used. For those chip selects SPI_CTAR even calculated offsets of non-existing registers.

commit a87fa1d8 upstream. The string property read helpers will run off the end of the buffer if it is handed a malformed string property. Rework the parsers to make sure that doesn't happen. At the same time add new test cases to make sure the functions behave themselves. The original implementations of of_property_read_string_index() and of_property_count_strings() both open-coded the same block of parsing code, each with it's own subtly different bugs. The fix here merges functions into a single helper and makes the original functions static inline wrappers around the helper. One non-bugfix aspect of this patch is the addition of a new wrapper, of_property_read_string_array(). The new wrapper is needed by the device_properties feature that Rafael is working on and planning to merge for v3.19. The implementation is identical both with and without the new static inline wrapper, so it just got left in to reduce the churn on the header file. Signed-off-by:

commit b45abacd upstream. The switch back is limited to ULT even on HP. The contrary finding arose by bad luck in BIOS versions for testing. This fixes spontaneous resume from S3 on some HP laptops. Signed-off-by:

commit c68929f7 upstream. Enable device-qualifier quirk for Elan Touchscreen, which often fails to handle requests for the device_descriptor. Note that the device sometimes do respond properly with a Request Error (three times as USB core retries), but usually fails to respond at all. When this happens any further descriptor requests also fails, for example: [ 1528.688934] usb 2-7: new full-speed USB device number 4 using xhci_hcd [ 1530.945588] usb 2-7: unable to read config index 0 descriptor/start: -71 [ 1530.945592] usb 2-7: can't read configurations, error -71 This has been observed repeating for over a minute before eventual successful enumeration.

commit 2a159389 upstream. Add new quirk for devices that cannot handle requests for the device_qualifier descriptor. A USB-2.0 compliant device must respond to requests for the device_qualifier descriptor (even if it's with a request error), but at least one device is known to misbehave after such a request.

commit 2391eacb upstream. Streams seem to be broken on the Asmedia 1042. An uas capable Seagate disk which is known to work fine with other controllers causes the system to freeze when connected over usb-3 with this controller, where as it works fine with uas in usb-2 ports, indicating a problem with streams. This is a bit bigger hammer then I would like to use for this, but for now it will have to make do. I've ordered a pci-e usb controller card with an Asmedia 1042, once that arrives I'll try to get streams to work (with a quirk flag if necessary) and then we can re-enable them. For now this at least makes uas capable disk enclosures work again by forcing fallback to the usb-storage driver. Reported-by:
