commit e0ccdef9 upstream. The primary changes in this patch are cleanups of __check_input_term() and move to a non-nested switch-case block by evaluating the pair of UAC version and the unit type, as we've done for parse_audio_unit(). Also each parser is split into the function for readability. Now, a slight behavior change by this cleanup is the handling of processing and extension units. Formerly we've dealt with them differently between UAC1/2 and UAC3; the latter returns an error if no input sources are available, while the former continues to parse. In this patch, unify the behavior in all cases: when input sources are available, it parses recursively, then override the type and the id, as well as channel information if not provided yet.

commit b8e4f1fd upstream. Now that we got the more comprehensive validation code for USB-audio descriptors, the check of overflow in each descriptor unit parser became superfluous. Drop some of the obvious cases. Signed-off-by:

commit 52c3e317 upstream. Instead of the direct kfree() calls, introduce a new local helper to release the usb_mixer_elem_info object. This will be extended to do more than a single kfree() in the later patches. Also, use the standard goto instead of multiple calls in parse_audio_selector_unit() error paths. Signed-off-by:

commit 68e9fde2 upstream. Minor code refactoring by combining the UAC version and the type in the switch-case flow, so that we reduce the indentation and redundancy. One good bonus is that the duplicated definition of the same type value (e.g. UAC2_EFFECT_UNIT) can be handled more cleanly. Signed-off-by:

commit 57f87706 upstream. Introduce a new helper to validate each audio descriptor unit before and check the unit before actually accessing it. This should harden against the OOB access cases with malformed descriptors that have been recently frequently reported by fuzzers. The existing descriptor checks are still kept although they become superfluous after this patch. They'll be cleaned up eventually later. Signed-off-by:

commit 351e5d86 upstream. Configfs abuses symlink(2). Unlike the normal filesystems, it wants the target resolved at symlink(2) time, like link(2) would've done. The problem is that ->symlink() is called with the parent directory locked exclusive, so resolving the target inside the ->symlink() is easily deadlocked. Short of really ugly games in sys_symlink() itself, all we can do is to unlock the parent before resolving the target and relock it after. However, that invalidates the checks done by the caller of ->symlink(), so we have to * check that dentry is still where it used to be (it couldn't have been moved, but it could've been unhashed) * recheck that it's still negative (somebody else might've successfully created a symlink with the same name while we were looking the target up) * recheck the permissions on the parent directory.

commit b0841eef upstream. Make sure that attribute methods are not called after the item has been removed from the tree. To do so, we * at the point of no return in removals, grab ->frag_sem exclusive and mark the fragment dead. * call the methods of attributes with ->frag_sem taken shared and only after having verified that the fragment is still alive. The main benefit is for method instances - they are guaranteed that the objects they are accessing *and* all ancestors are still there. Another win is that we don't need to bother with extra refcount on config_item when opening a file - the item will be alive for as long as it stays in the tree, and we won't touch it/attributes/any associated data after it's been removed from the tree.

commit f19e4ed1 upstream. revert cc57c073 "configfs: fix registered group removal" It was an attempt to handle something that fundamentally doesn't work - configfs_register_group() should never be done in a part of tree that can be rmdir'ed. And in mainline it never had been, so let's not borrow trouble; the fix was racy anyway, it would take a lot more to make that work and desired semantics is not clear. Signed-off-by:

commit ca913f1a upstream. If the rx-offload skb_queue is full can_rx_offload_queue_sorted() will not queue the skb and return with an error. None of the callers of this function, issue a kfree_skb() to free the not queued skb. This results in a memory leak. This patch fixes the problem by freeing the skb in case of a full queue. The return value is adjusted to -ENOBUFS to better reflect the actual problem. The device stats handling is left to the callers, as this function might be used in both the rx and tx path.

commit de280f40 upstream. When decoding a buffer received from PCAN-USB, the first timestamp read in a packet is a 16-bit coded time base, and the next ones are an 8-bit offset to this base, regardless of the type of packet read. This patch corrects a potential loss of synchronization by using a timestamp index read from the buffer, rather than an index of received data packets, to determine on the sizeof the timestamp to be read from the packet being decoded.

commit 3cb3eaac upstream. When the status register is read without the status IRQ pending, the chip may not raise the interrupt line for an upcoming status interrupt and the driver may miss a status interrupt. It is critical that the BUSOFF status interrupt is forwarded to the higher layers, since no more interrupts will follow without intervention. Thanks to Wolfgang and Joe for bringing up the first idea. Signed-off-by:

commit d243af7a upstream. When the client hits a network reconnect, it re-opens every open file with a create context to reconnect a persistent handle. All create context types should be 8-bytes aligned but the padding was missed for that one. As a result, some servers don't allow us to reconnect handles and return an error. The problem occurs when the problematic context is not at the end of the create request packet. Fix this by adding a proper padding at the end of the reconnect persistent handle context.

commit fe6f85ca upstream. The removal of the LDR initialization in the bigsmp_32 APIC code unearthed a problem in setup_local_APIC(). The code checks unconditionally for a mismatch of the logical APIC id by comparing the early APIC id which was initialized in get_smp_config() with the actual LDR value in the APIC. Due to the removal of the bogus LDR initialization the check now can trigger on bigsmp_32 APIC systems emitting a warning for every booting CPU. This is of course a false positive because the APIC is not using logical destination mode. Restrict the check and the possibly resulting fixup to systems which are actually using the APIC in logical destination mode.

commit ff479731 upstream. The HID descriptors for most Wacom devices oddly declare the serial number and other related fields as signed integers. When these numbers are ingested by the HID subsystem, they are automatically sign-extended into 32-bit integers. We treat the fields as unsigned elsewhere in the kernel and userspace, however, so this sign-extension causes problems. In particular, the sign-extended tool ID sent to userspace as ABS_MISC does not properly match unsigned IDs used by xf86-input-wacom and libwacom. We introduce a function 'wacom_s32tou' that can undo the automatic sign extension performed by 'hid_snto32'. We call this function when processing the serial number and related fields to ensure that we are dealing with and reporting the unsigned form. We opt to use this method rather than adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be more robust in the face of future devices.

commit 5cbf2fff upstream. In the current code, we use the atomic_cmpxchg() to serialize the output of the dump_stack(), but this implementation suffers the thundering herd problem. We have observed such kind of livelock on a Marvell cn96xx board(24 cpus) when heavily using the dump_stack() in a kprobe handler. Actually we can let the competitors to wait for the releasing of the lock before jumping to atomic_cmpxchg(). This will definitely mitigate the thundering herd problem.

commit abaed011 upstream. /proc/pagetypeinfo is a debugging tool to examine internal page allocator state wrt to fragmentation. It is not very useful for any other use so normal users really do not need to read this file. Waiman Long has noticed that reading this file can have negative side effects because zone->lock is necessary for gathering data and that a) interferes with the page allocator and its users and b) can lead to hard lockups on large machines which have very long free_list. Reduce both issues by simply not exporting the file to regular users.
