Anyway, this is a collection of lots of small fixes that slipped from the previous pull request. All fixes are about ASoC, and the majority of changes are corrections of the wrong access types in ALSA ctl enum items. They are mostly harmless on 32bit architectures, but actually buggy on 64bit. So we addressed all these now in a shot. The rest are various small ASoC driver fixes. Among them, only two changes have been done to ASoC core, and both of them are trivial. The rest are all device-specific. So overall, they should be safe to apply" * tag 'sound-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (33 commits) ASoC: wm_adsp: Fix enum ctl accesses in a wrong type ASoC: wm9081: Fix enum ctl accesses in a wrong type ASoC: wm8996: Fix enum ctl accesses in a wrong type ASoC: wm8994: Fix enum ctl accesses in a wrong type ASoC: wm8985: Fix enum ctl accesses in a wrong type ASoC: wm8983: Fix enum ctl accesses in a wrong type ASoC: wm8958: Fix enum ctl accesses in a wrong type ASoC: wm8904: Fix enum ctl accesses in a wrong type ASoC: wm8753: Fix enum ctl accesses in a wrong type ASoC: wl1273: Fix enum ctl accesses in a wrong type ASoC: tlv320dac33: Fix enum ctl accesses in a wrong type ASoC: max98095: Fix enum ctl accesses in a wrong type ASoC: max98088: Fix enum ctl accesses in a wrong type ASoC: ab8500: Fix enum ctl accesses in a wrong type ASoC: da732x: Fix enum ctl accesses in a wrong type ASoC: cs42l51: Fix enum ctl accesses in a wrong type ASoC: intel: mfld: Fix enum ctl accesses in a wrong type ASoC: omap: rx51: Fix enum ctl accesses in a wrong type ASoC: omap: n810: Fix enum ctl accesses in a wrong type ASoC: pxa: tosa: Fix enum ctl accesses in a wrong type ... 08 March 2016, 17:41:20 UTC

256faed Linus Torvalds 07 March 2016, 21:15:09 UTC Revert "drm/radeon: call hpd_irq_event on resume" This reverts commit dbb17a21c131eca94eb31136eee9a7fe5aff00d9. It turns out that commit can cause problems for systems with multiple GPUs, and causes X to hang on at least a HP Pavilion dv7 with hybrid graphics. This got noticed originally in 4.4.4, where this patch had already gotten back-ported, but 4.5-rc7 was verified to have the same problem. Alexander Deucher says: "It looks like you have a muxed system so I suspect what's happening is that one of the display is being reported as connected for both the IGP and the dGPU and then the desktop environment gets confused or there some sort problem in the detect functions since the mux is not switched to the dGPU. I don't see an easy fix unless Dave has any ideas. I'd say just revert for now" Reported-by: Jörg-Volker Peetz <jvpeetz@web.de> Acked-by: Alexander Deucher <Alexander.Deucher@amd.com> Cc: Dave Airlie <airlied@gmail.com> Cc: stable@kernel.org # wherever dbb17a21c131 got back-ported Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 07 March 2016, 21:15:09 UTC

59dca1d Bill Sommerfeld 04 March 2016, 22:47:21 UTC udp6: fix UDP/IPv6 encap resubmit path IPv4 interprets a negative return value from a protocol handler as a request to redispatch to a new protocol. In contrast, IPv6 interprets a negative value as an error, and interprets a positive value as a request for redispatch. UDP for IPv6 was unaware of this difference. Change __udp6_lib_rcv() to return a positive value for redispatch. Note that the socket's encap_rcv hook still needs to return a negative value to request dispatch, and in the case of IPv6 packets, adjust IP6CB(skb)->nhoff to identify the byte containing the next protocol.

cec0556 Neil Horman 04 March 2016, 18:40:48 UTC vmxnet3: avoid calling pskb_may_pull with interrupts disabled vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations, uses pskb_may_pull to linearize the header portion of an skb. That operation eventually uses local_bh_disable/enable to ensure that it doesn't race with the drivers bottom half handler. Unfortunately, vmxnet3 preforms this parse_and_copy operation with a spinlock held and interrupts disabled. This causes us to run afoul of the WARN_ON_ONCE(irqs_disabled()) warning in local_bh_enable, resulting in this: WARNING: at kernel/softirq.c:159 local_bh_enable+0x59/0x90() (Not tainted) Hardware name: VMware Virtual Platform Modules linked in: ipv6 ppdev parport_pc parport microcode e1000 vmware_balloon vmxnet3 i2c_piix4 sg ext4 jbd2 mbcache sd_mod crc_t10dif sr_mod cdrom mptspi mptscsih mptbase scsi_transport_spi pata_acpi ata_generic ata_piix vmwgfx ttm drm_kms_helper drm i2c_core dm_mirror dm_region_hash dm_log dm_mod [last unloaded: mperf] Pid: 6229, comm: sshd Not tainted 2.6.32-616.el6.i686 #1 Call Trace: [<c04624d9>] ? warn_slowpath_common+0x89/0xe0 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c046254b>] ? warn_slowpath_null+0x1b/0x20 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c07bb936>] ? skb_copy_bits+0x126/0x210 [<f8d1d9fe>] ? ext4_ext_find_extent+0x24e/0x2d0 [ext4] [<c07bc49e>] ? __pskb_pull_tail+0x6e/0x2b0 [<f95a6164>] ? vmxnet3_xmit_frame+0xba4/0xef0 [vmxnet3] [<c05d15a6>] ? selinux_ip_postroute+0x56/0x320 [<c0615988>] ? cfq_add_rq_rb+0x98/0x110 [<c0852df8>] ? packet_rcv+0x48/0x350 [<c07c5839>] ? dev_queue_xmit_nit+0xc9/0x140 ... Fix it by splitting vmxnet3_parse_and_copy_hdr into two functions: vmxnet3_parse_hdr, which sets up the internal/on stack ctx datastructure, and pulls the skb (both of which can be done without holding the spinlock with irqs disabled and vmxnet3_copy_header, which just copies the skb to the tx ring under the lock safely. tested and shown to correct the described problem.

5091730 Ido Schimmel 07 March 2016, 14:15:30 UTC mlxsw: pci: Correctly determine if descriptor queue is full The descriptor queues for sending (SDQs) and receiving (RDQs) packets are managed by two counters - producer and consumer - which are both 16-bit in size. A queue is considered full when the difference between the two equals the queue's maximum number of descriptors. However, if the producer counter overflows, then it's possible for the full queue check to fail, as it doesn't take the overflow into account. In such a case, descriptors already passed to the device - but for which a completion has yet to be posted - will be overwritten, thereby causing undefined behavior. The above can be achieved under heavy load (~30 netperf instances). Fix that by casting the subtraction result to u16, preventing it from being treated as a signed integer.

They aren't all tagged to stable since some of these chips have vanishingly little chance of being used in 64 bit systems. The other changes are: - A fix for Qualcomm devices to work on big endian systems. The original change is actually correct but triggered a bug in regmap which is too invasive to fix for this cycle and can be worked around by just letting regmap pick the default. - A fix for the Samsung I2S driver locking which wasn't using IRQ safe spinlocks when it needed to. - A fix for the new Intel Sky Lake driver forgetting that C pointer arithmetic takes the type of the pointer into consideration. - A revert of a change to the FSL SSI driver that broke some systems. - A fix for the cleanup path of the wm9713 driver. - A fix for some incorrect register definitions in the ADAU17x1 driver that caused misclocking in some configurations. - A fix for the tracepoints for jack detection to avoid using an internal field of the core jack structure which is no longer present in all configurations. - A fix for another of the new Intel drivers which tried to write to a string literal. 07 March 2016, 10:06:46 UTC

But this prevented filtering on a comm field that is within a trace event (like sched_migrate_task). When trying to filter on when a program migrated, this change prevented the filtering of the sched_migrate_task. To fix this, the event fields are examined first, and then the extra fields like "comm" and "cpu" are examined. Also, instead of testing to assign the comm filter function based on the field's name, the generic comm field is given a new filter type (FILTER_COMM). When this field is used to filter the type is checked. The same is done for the cpu filter field. Two new special filter types are added: "COMM" and "CPU". This allows users to still filter the tasks comm for events that have "comm" as one of their fields, in cases that users would like to filter sched_migrate_task on the comm of the task that called the event, and not the comm of the task that is being migrated" * tag 'trace-fixes-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not have 'comm' filter override event 'comm' field 05 March 2016, 00:57:04 UTC

e57cbaf Steven Rostedt (Red Hat) 03 March 2016, 22:18:20 UTC tracing: Do not have 'comm' filter override event 'comm' field Commit 9f61668073a8d "tracing: Allow triggers to filter for CPU ids and process names" added a 'comm' filter that will filter events based on the current tasks struct 'comm'. But this now hides the ability to filter events that have a 'comm' field too. For example, sched_migrate_task trace event. That has a 'comm' field of the task to be migrated. echo 'comm == "bash"' > events/sched_migrate_task/filter will now filter all sched_migrate_task events for tasks named "bash" that migrates other tasks (in interrupt context), instead of seeing when "bash" itself gets migrated. This fix requires a couple of changes. 1) Change the look up order for filter predicates to look at the events fields before looking at the generic filters. 2) Instead of basing the filter function off of the "comm" name, have the generic "comm" filter have its own filter_type (FILTER_COMM). Test against the type instead of the name to assign the filter function. 3) Add a new "COMM" filter that works just like "comm" but will filter based on the current task, even if the trace event contains a "comm" field. Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU".

909c3a2 Filipe Manana 02 March 2016, 15:49:38 UTC Btrfs: fix loading of orphan roots leading to BUG_ON When looking for orphan roots during mount we can end up hitting a BUG_ON() (at root-item.c:btrfs_find_orphan_roots()) if a log tree is replayed and qgroups are enabled. This is because after a log tree is replayed, a transaction commit is made, which triggers qgroup extent accounting which in turn does backref walking which ends up reading and inserting all roots in the radix tree fs_info->fs_root_radix, including orphan roots (deleted snapshots). So after the log tree is replayed, when finding orphan roots we hit the BUG_ON with the following trace: [118209.182438] ------------[ cut here ]------------ [118209.183279] kernel BUG at fs/btrfs/root-tree.c:314!

c1bb0a5 Venkat Duvvuru 02 March 2016, 11:00:28 UTC be2net: don't enable multicast flag in be_enable_if_filters() routine When the interface is opened (in be_open()) the routine be_enable_if_filters() must be called to switch on the basic filtering capabilities of an interface that are not changed at run-time. These include the flags UNTAGGED, BROADCAST and PASS_L3L4_ERRORS. Other flags such as MULTICAST and PROMISC must be enabled later by be_set_rx_mode() based on the state in the netdev/adapter struct. be_enable_if_filters() routine is wrongly trying to enable MULTICAST flag without checking the current adapter state. This can cause the RX_FILTER cmds to the FW to fail. This patch fixes this problem by only enabling the basic filtering flags in be_enable_if_filters(). The VF must be able to issue RX_FILTER cmd with any filter flag, as long as the PF allowed those flags (if_cap_flags) in the iface it provisioned for the VF. This rule is applicable even when the VF doesn't have the FILTMGMT privilege. There is a bug in BE3 FW that wrongly fails RX_FILTER multicast programming cmds on VFs that don't have FILTMGMT privilege. This patch also helps in insulating the VF driver from be_open failures due to the FW bug.

F.e. in ovs, ovs_flow_key_extract() checks for options_len before extracting the data through ip_tunnel_info_opts_get(). Geneve uses ip_tunnel_info_opts_set() helper in receive path, which sets options_len internally, vxlan however uses ip_tunnel_info_opts(), so when filling vxlan_metadata, we do need to update options_len.

4d6af73 Christoph Hellwig 02 March 2016, 17:07:14 UTC block: support large requests in blk_rq_map_user_iov This patch adds support for larger requests in blk_rq_map_user_iov by allowing it to build multiple bios for a request. This functionality used to exist for the non-vectored blk_rq_map_user in the past, and this patch reuses the existing functionality for it on the unmap side, which stuck around. Thanks to the iov_iter API supporting multiple bios is fairly trivial, as we can just iterate the iov until we've consumed the whole iov_iter.

a1a0e23 Tejun Heo 29 February 2016, 23:28:53 UTC writeback: flush inode cgroup wb switches instead of pinning super_block If cgroup writeback is in use, inodes can be scheduled for asynchronous wb switching. Before 5ff8eaac1636 ("writeback: keep superblock pinned during cgroup writeback association switches"), this could race with umount leading to super_block being destroyed while inodes are pinned for wb switching. 5ff8eaac1636 fixed it by bumping s_active while wb switches are in flight; however, this allowed in-flight wb switches to make umounts asynchronous when the userland expected synchronosity - e.g. fsck immediately following umount may fail because the device is still busy. This patch removes the problematic super_block pinning and instead makes generic_shutdown_super() flush in-flight wb switches. wb switches are now executed on a dedicated isw_wq so that they can be flushed and isw_nr_in_flight keeps track of the number of in-flight wb switches so that flushing can be avoided in most cases. v2: Move cgroup_writeback_umount() further below and add MS_ACTIVE check in inode_switch_wbs() as Jan an Al suggested.

e9fc63d Keith Busch 24 February 2016, 16:15:58 UTC NVMe: Fix 0-length integrity payload A user could send a passthrough IO command with a metadata pointer to a namespace without metadata. With metadata length of 0, kmalloc returns ZERO_SIZE_PTR. Since that is not NULL, the driver would have set this as the bio's integrity payload, which causes an access fault on completion. This patch ignores the users metadata buffer if the namespace format does not support separate metadata.

69d9a99 Keith Busch 24 February 2016, 16:15:56 UTC NVMe: Move error handling to failed reset handler This moves failed queue handling out of the namespace removal path and into the reset failure path, fixing a hanging condition if the controller fails or link down during del_gendisk. Previously the driver had to see the controller as degraded prior to calling del_gendisk to setup the queues to fail. But, if the controller happened to fail after this, there was no task to end outstanding requests. On failure, all namespace states are set to dead. This has capacity revalidate to 0, and ends all new requests with error status.

646017a Keith Busch 24 February 2016, 16:15:54 UTC NVMe: Fix namespace removal deadlock This patch makes nvme namespace removal lockless. It is up to the caller to ensure no active namespace scanning is occuring. To ensure no scan work occurs, the nvme pci driver adds a removing state to the controller device to avoid queueing scan work during removal. The work is flushed after setting the state, so no new scan work can be queued. The lockless removal allows the driver to cleanup a namespace request_queue if the controller fails during removal. Previously this could deadlock trying to acquire the namespace mutex in order to handle such events.
