commit 727b9784b6085c99c2f836bf4fcc2848dc9cf904 upstream. Orphans in the fs tree are cleaned up via open_ctree and subvolume orphans are cleaned via btrfs_lookup_dentry -- except when a default subvolume is in use. The name for the default subvolume uses a manual lookup that doesn't trigger orphan cleanup and needs to trigger it manually as well. This doesn't apply to the remount case since the subvolumes are cleaned up by walking the root radix tree. Signed-off-by:

commit 26e726afe01c1c82072cf23a5ed89ce25f39d9f2 upstream. fiemap_fill_next_extent returns 0 on success, -errno on error, 1 if this was the last extent that will fit in user array. If 1 is returned, the return value may eventually returned to user space, which should not happen, according to manpage of ioctl. Signed-off-by:

commit 9c5a18a31b321f120efda412281bb9f610f84aa0 upstream. Until recently, mac80211 overwrote all the statistics it could provide when getting called, but it now relies on the struct having been zeroed by the caller. This was always the case in nl80211, but wext used a static struct which could even cause values from one device leak to another. Using a static struct is OK (as even documented in a comment) since the whole usage of this function and its return value is always locked under RTNL. Not clearing the struct for calling the driver has always been wrong though, since drivers were free to only fill values they could report, so calling this for one device and then for another would always have leaked values from one to the other. Fix this by initializing the structure in question before the driver method call. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=99691Reported-by:

When hot re-add a node, we will reuse the pgdat of it, so does the zone struct, and when add pages to the target zone, it will init the zone first (including the wait_table) if the zone is not initialized. The judgement of zone initialized is based on zone->wait_table: static inline bool zone_is_initialized(struct zone *zone) { return !!zone->wait_table; } so if we do not set the zone->wait_table to *NULL* after free it, the memory hotplug routine will skip the init of new zone when hot re-add the node, and the wait_table still points to the freed memory, then we will access the invalid address when trying to wake up the waiting people after the i/o operation with the page is done, such as mentioned above.

commit 3f5f1554ee715639e78d9be87623ee82772537e0 upstream. Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI devices, as they do not have a sink device in them to respond to any AUX traffic. When probing these dongles over the DDC, sometimes they will NAK the first attempt even though the transaction is valid and they support the DDC protocol. The retry loop inside of drm_do_probe_ddc_edid() would normally catch this case and try the transaction again, resulting in success. That, however, was thwarted by the fix for [1]: commit 9292f37e Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Thu Jan 5 09:34:28 2012 -0200 drm: give up on edid retries when i2c bus is not responding This added code to exit immediately if the return code from the i2c_transfer function was -ENXIO in order to reduce the amount of time spent in waiting for unresponsive or disconnected devices. That was possible because the underlying i2c bit banging algorithm had retries of its own (which, of course, were part of the reason for the bug the commit fixes). Since its introduction in commit f899fc64 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links we've been flipping back and forth enabling the GMBUS transfers, but we've settled since then. The GMBUS implementation does not do any retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop on first encounter of -ENXIO. This, combined with Eugeni's commit, broke the retry on -ENXIO. Retry GMBUS once on -ENXIO on first message to mitigate the issues with passive adapters. This patch is based on the work, and commit message, by Todd Previte <tprevite@gmail.com>. [1] https://bugs.freedesktop.org/show_bug.cgi?id=41059 v2: Don't retry if using bit banging. v3: Move retry within gmbux_xfer, retry only on first message. v4: Initialize GMBUS0 on retry (Ville). v5: Take index reads into account (Ville).

commit 9a59029bc218b48eff8b5d4dde5662fd79d3e1a8 upstream. The subtraction here was using a signed integer and did not have any bounds checking at all.

commit d114b9fe78c8d6fc6e70808c2092aa307c36dc8e upstream. Since elt->length is a u8, we can make this variable a u8. Then we can do proper bounds checking more easily. Without this, a potentially negative value is passed to the memcpy inside oz_hcd_get_desc_cnf, resulting in a remotely exploitable heap overflow with network supplied data. This could result in remote code execution. A PoC which obtains DoS follows below.

commit 5f35b9cd553fd64415b563497d05a563c988dbd6 upstream. Commit 334c86c4 ("MIPS: IRQ: Add stackoverflow detection") added kernel stack overflow detection, however it only enabled it conditional upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so switch it to using that definition instead.

commit c2a8b623a089d52c199e305e7905829907db8ec8 upstream. We unfortunately can't use ~0UL for the scan mask to indicate that the only valid scan mask is all channels selected. The IIO core needs the exact mask to work correctly and not a super-set of it. So calculate the masked based on the channels that are available for a particular device. Signed-off-by:

Previously, the two voltage channels had the same ID, which didn't cause conflicts in sysfs only because one channel is named and the other isn't; this is still violating the spec though, two indexed channels should never have the same index.
