commit 6d19375b upstream. Justin and Chris spotted that iptables NFLOG target was broken when they upgraded the kernel to 4.8: "ulogd-2.0.5- IPs are no longer logged" or "results in segfaults in ulogd-2.0.5". Because "struct nf_loginfo li;" is a local variable, and flags will be filled with garbage value, not inited to zero. So if it contains 0x1, packets will not be logged to the userspace anymore. Fixes: 7643507f ("netfilter: xt_NFLOG: nflog-range does not truncate packets") Reported-by:

commit 6a676fb6 upstream. Instantiated I2C device nodes are marked with OF_POPULATE. This was introduced in 4f001fd3. On unloading, loaded device nodes will of course be unmarked. The problem are nodes that fail during initialisation: If a node fails, it won't be unloaded and hence not be unmarked. If a I2C driver module is unloaded and reloaded, it will skip nodes that failed before. Skip device nodes that are already populated and mark them only in case of success.

commit e3b9e6e3 upstream. Broadwell and newer actually compress up to 2560 lines instead of 2048 (as documented in the FBC_CTL page). If we don't take this into consideration we end up reserving too little stolen memory for the CFB, so we may allocate something else (such as a ring) right after what we reserved, and the hardware will overwrite it with the contents of the CFB when FBC is active, causing GPU hangs. Another possibility is that the CFB may be allocated at the very end of the available space, so the CFB will overlap the reserved stolen area, leading to FIFO underruns. This bug has always been a problem on BDW (the only affected platform where FBC is enabled by default), but it's much easier to reproduce since the following commit: commit c58b735f Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Aug 18 17:16:57 2016 +0100 drm/i915: Allocate rings from stolen Of course, you can only reproduce the bug if your screen is taller than 2048 lines.

commit 198c5ee3 upstream. The VBT provides the platform a way to mix and match the DDI ports vs. AUX channels. Currently we only trust the VBT for DDI E, which has no corresponding AUX channel of its own. However it is possible that some board might use some non-standard DDI vs. AUX port routing even for the other ports. Perhaps for signal routing reasons or something, So let's generalize this and trust the VBT for all ports. For now we'll limit this to DDI platforms, as we trust the VBT a bit more there anyway when it comes to the DDI ports. I've structured the code in a way that would allow us to easily expand this to other platforms as well, by simply filling in the ddi_port_info. v2: Drop whitespace changes, keep MISSING_CASE() for unknown aux ch assignment, include a commit message, include debug message during init Cc: Maarten Maathuis <madman2003@gmail.com> Tested-by:

commit 01c72d6c upstream. With the previous code we were only recomputing the DDB partitioning for the CRTCs included in the atomic commit, so any other active CRTCs would end up having their DDB registers zeroed. In this patch we make sure that the computed state starts as a copy of the current partitioning, and then we only zero the DDBs that we're actually going to recompute. How to reproduce the bug: 1 - Enable the primary plane on pipe A 2 - Enable the primary plane on pipe B 3 - Enable the cursor or sprite plane on pipe A Step 3 will zero the DDB partitioning for pipe B since it's not included in the commit that enabled the cursor or sprite for pipe A. I expect this to fix many FIFO underrun problems on gen9+. v2: - Mention the cursor on the steps to reproduce the problem (Paulo). - Add Testcase tag provided by Maarten (Maarten).

commit a2889606 upstream. The fbdev helper code keeps around two lists of connectors. One is the list of all connectors it could use, and that list already holds references for all the connectors. However the other list, or rather lists, is the one actively being used. That list is tracked per-crtc and currently doesn't hold any extra references. Let's grab those extra references to avoid oopsing when the connector vanishes. The list of all possible connectors should get updated when the hpd happens, but the list of actively used connectors would not get updated until the next time the fb-helper picks through the set of possible connectors. And so we need to hang on to the connectors until that time. Since we need to clean up in drm_fb_helper_crtc_free() as well, let's pull the code to a common place. And while at it let's pull in up the modeset->mode cleanup in there as well. The case of modeset->fb is a bit less clear. I'm thinking we should probably hold a reference to it, but for now I just slapped on a FIXME. v2: Cleanup things drm_fb_helper_crtc_free() too (Chris) v3: Don't leak modeset->connectors (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Carlos Santa <carlos.santa@intel.com> Cc: Kirill A.

commit 87d3b658 upstream. Since 4.7 kernel, we've seen the error messages like kernel: [TTM] Buffer eviction failed kernel: qxl 0000:00:02.0: object_init failed for (4026540032, 0x00000001) kernel: [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO on QXL when switching and accessing on VT. The culprit was the generic deferred_io code (qxl driver switched to it since 4.7). There is a race between the dirty clip update and the call of callback. In drm_fb_helper_dirty(), the dirty clip is updated in the spinlock, while it kicks off the update worker outside the spinlock. Meanwhile the update worker clears the dirty clip in the spinlock, too. Thus, when drm_fb_helper_dirty() is called concurrently, schedule_work() is called after the clip is cleared in the first worker call. This patch addresses it by validating the clip before calling the dirty fb callback.

commit b0a6af8b upstream. Check whether the kernel really supports power resources for a device, otherwise the power might not be removed when the device is runtime suspended (DSM should still work in these cases where PR does not). This is a workaround for a problem where ACPICA and Windows 10 differ in behavior. ACPICA does not correctly enumerate power resources within a conditional block (due to delayed execution of such blocks) and as a result power_resources is set to false even if _PR3 exists.

commit 537b4b46 upstream. The read is taking a considerable amount of time (about 50us on this machine). The register does not ever hold anything other than the ring ID that is updated in this exact function, so there is no need for the read modify write cycle. This chops off a big chunk of the time spent in hardirq disabled context, as this function is called multiple times in the interrupt handler. With this change applied radeon won't show up in the list of the worst IRQ latency offenders anymore, where it was a regular before. Reviewed-by:

So, looking at old_plane_state->fb to determine whether we need to switch EBA buffer(for hardware double buffering) in ipu_plane_atomic_set_base() or not is no more correct.

commit 1217e1d1 upstream. mddev->curr_resync usually records where the current resync is up to, but during the starting phase it has some "magic" values. 1 - means that the array is trying to start a resync, but has yielded to another array which shares physical devices, and also needs to start a resync 2 - means the array is trying to start resync, but has found another array which shares physical devices and has already started resync. 3 - means that resync has commensed, but it is possible that nothing has actually been resynced yet. It is important that this value not be visible to user-space and particularly that it doesn't get written to the metadata, as the resync or recovery checkpoint. In part, this is because it may be slightly higher than the correct value, though this is very rare. In part, because it is not a multiple of 4K, and some devices only support 4K aligned accesses. There are two places where this value is propagates into either ->curr_resync_completed or ->recovery_cp or ->recovery_offset. These currently avoid the propagation of values 1 and 3, but will allow 3 to leak through. Change them to only propagate the value if it is > 3. As this can cause an array to fail, the patch is suitable for -stable. Reported-by:

commit 579ed34f upstream. This is the counterpart of raid10 fix. If a write error occurs, raid10 will try to rewrite the bio in small chunk size. If the rewrite fails, raid10 will record the error in bad block. narrow_write_error will always use WRITE for the bio, but actually it could be a discard. Since discard bio hasn't payload, write the bio will cause different issues. But discard error isn't fatal, we can safely ignore it. This is what this patch does. This issue should exist since discard is added, but only exposed with recent arbitrary bio size feature. Cc: Sitsofe Wheeler <sitsofe@gmail.com> Signed-off-by:

commit f67b107d upstream. Commit 0b8e3c4c ("ath10k: move cal data len to hw_params") broke retrieving the calibration data from cal_data debugfs file. The length of file was always zero. The reason is: static ssize_t ath10k_debug_cal_data_read(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) { struct ath10k *ar = file->private_data; void *buf = file->private_data; This is obviously bogus, private_data cannot contain both struct ath10k and the buffer. Fix it by caching calibration data to ar->debug.cal_data. This also allows it to be accessed when the device is not active (interface is down). The cal_data buffer is fixed size because during the first firmware probe we don't yet know what will be the lenght of the calibration data. It was simplest just to use a fixed length. There's a WARN_ON() in ath10k_debug_cal_data_fetch() if the buffer is too small. Tested with qca988x and firmware 10.2.4.70.56. Reported-by:

commit e9300a4b upstream. RFC 2734 defines the datagram_size field in fragment encapsulation headers thus: datagram_size: The encoded size of the entire IP datagram. The value of datagram_size [...] SHALL be one less than the value of Total Length in the datagram's IP header (see STD 5, RFC 791). Accordingly, the eth1394 driver of Linux 2.6.36 and older set and got this field with a -/+1 offset: ether1394_tx() /* transmit */ ether1394_encapsulate_prep() hdr->ff.dg_size = dg_size - 1; ether1394_data_handler() /* receive */ if (hdr->common.lf == ETH1394_HDR_LF_FF) dg_size = hdr->ff.dg_size + 1; else dg_size = hdr->sf.dg_size + 1; Likewise, I observe OS X 10.4 and Windows XP Pro SP3 to transmit 1500 byte sized datagrams in fragments with datagram_size=1499 if link fragmentation is required. Only firewire-net sets and gets datagram_size without this offset. The result is lacking interoperability of firewire-net with OS X, Windows XP, and presumably Linux' eth1394. (I did not test with the latter.) For example, FTP data transfers to a Linux firewire-net box with max_rec smaller than the 1500 bytes MTU - from OS X fail entirely, - from Win XP start out with a bunch of fragmented datagrams which time out, then continue with unfragmented datagrams because Win XP temporarily reduces the MTU to 576 bytes. So let's fix firewire-net's datagram_size accessors. Note that firewire-net thereby loses interoperability with unpatched firewire-net, but only if link fragmentation is employed. (This happens with large broadcast datagrams, and with large datagrams on several FireWire CardBus cards with smaller max_rec than equivalent PCI cards, and it can be worked around by setting a small enough MTU.)

commit 667121ac upstream. The IP-over-1394 driver firewire-net lacked input validation when handling incoming fragmented datagrams. A maliciously formed fragment with a respectively large datagram_offset would cause a memcpy past the datagram buffer. So, drop any packets carrying a fragment with offset + length larger than datagram_size. In addition, ensure that - GASP header, unfragmented encapsulation header, or fragment encapsulation header actually exists before we access it, - the encapsulated datagram or fragment is of nonzero size.

Fix validation path for old superblocks by reverting to the old raid4 layout and basing checks on mddev->new_{level,layout,...} members in super_init_validation(). Signed-off-by:

commit 5c33677c upstream. In ecbfb9f1 ("dm raid: add raid level takeover support") a new compatible feature flag was added. Validation for these compat_features was added but this only passes for new raid mappings with this feature flag. This causes previously created raid mappings to be failed at import. Check compat_features for the only valid combination. Fixes: ecbfb9f1 ("dm raid: add raid level takeover support") Signed-off-by:

commit 937fa62e upstream. cleanup_mapped_device() calls kthread_stop() if kworker_task is non-NULL. Currently the assigned value could be a valid task struct or an error code (e.g -ENOMEM). Reset md->kworker_task to NULL if kthread_run() returned an erorr. Fixes: 7193a9de ("dm rq: check kthread_run return for .request_fn request-based DM") Reported-by:

commit dafa724b upstream. dm_get_target_type() was previously called so any error returned from dm_table_add_target() must first call dm_put_target_type(). Otherwise the DM target module's reference count will leak and the associated kernel module will be unable to be removed. Also, leverage the fact that r is already -EINVAL and remove an extra newline.

commit dcb2ff56 upstream. If a default leg has failed, any read will cause a new operational default leg to be selected and the read is resubmitted. But until now the read will return failure even though it was successful due to resubmission. The reason for this is bio->bi_error was not being cleared before resubmitting the bio. Fix by clearing bio->bi_error before resubmission. Fixes: 4246a0b6 ("block: add a bi_error field to struct bio") Signed-off-by:
