2020-04-22RDMA/core: Prevent mixed use of FDs between shared ufilesLeon Romanovsky
FDs can only be used on the ufile that created them, they cannot be mixed to other ufiles. We are lacking a check to prevent it.

2020-04-22RDMA/uverbs: Fix a race with disassociate and exit_mmap()Jason Gunthorpe
If uverbs_user_mmap_disassociate() is called while the mmap is concurrently doing exit_mmap then the ordering of the rdma_user_mmap_entry_put() is not reliable. The put must be done before uvers_user_mmap_disassociate() returns, otherwise there can be a use after free on the ucontext, and a left over entry in the xarray. If the put is not done here then it is done during rdma_umap_close() later. Add the missing put to the error exit path.

2020-04-22RDMA/mlx5: Set GRH fields in query QP on RoCEAharon Landau
GRH fields such as sgid_index, hop limit, et. are set in the QP context when QP is created/modified. Currently, when query QP is performed, we fill the GRH fields only if the GRH bit is set in the QP context, but this bit is not set for RoCE. Adjust the check so we will set all relevant data for the RoCE too. Since this data is returned to userspace, the below is an ABI regression.

2020-04-22mmc: sdhci-pci: Fix eMMC driver strength for BYT-based controllersAdrian Hunter
BIOS writers have begun the practice of setting 40 ohm eMMC driver strength even though the eMMC may not support it, on the assumption that the kernel will validate the value against the eMMC (Extended CSD DRIVER_STRENGTH [offset 197]) and revert to the default 50 ohm value if 40 ohm is invalid. This is done to avoid changing the value for different boards. Putting aside the merits of this approach, it is clear the eMMC's mask of supported driver strengths is more reliable than the value provided by BIOS. Add validation accordingly.

2020-04-22s390/pci: do not set affinity for floating irqsNiklas Schnelle
with the introduction of CPU directed interrupts the kernel parameter pci=force_floating was introduced to fall back to the previous behavior using floating irqs. However we were still setting the affinity in that case, both in __irq_alloc_descs() and via the irq_set_affinity callback in struct irq_chip. For the former only set the affinity in the directed case. The latter is explicitly set in zpci_directed_irq_init() so we can just leave it unset for the floating case.

2020-04-22ALSA: usb-audio: Add connector notifier delegationTakashi Iwai
It turned out that ALC1220-VB USB-audio device gives the interrupt event to some PCM terminals while those don't allow the connector state request but only the actual I/O terminals return the request. The recent commit 7dc3c5a0172e ("ALSA: usb-audio: Don't create jack controls for PCM terminals") excluded those phantom terminals, so those events are ignored, too. My first thought was that this could be easily deduced from the associated terminals, but some of them have even no associate terminal ID, hence it's not too trivial to figure out. Since the number of such terminals are small and limited, this patch implements another quirk table for the simple mapping of the connectors. It's not really scalable, but let's hope that there will be not many such funky devices in future.

2020-04-22scsi: target/iblock: fix WRITE SAME zeroingDavid Disseldorp
SBC4 specifies that WRITE SAME requests with the UNMAP bit set to zero "shall perform the specified write operation to each LBA specified by the command". Commit 2237498f0b5c ("target/iblock: Convert WRITE_SAME to blkdev_issue_zeroout") modified the iblock backend to call blkdev_issue_zeroout() when handling WRITE SAME requests with UNMAP=0 and a zero data segment. The iblock blkdev_issue_zeroout() call incorrectly provides a flags parameter of 0 (bool false), instead of BLKDEV_ZERO_NOUNMAP. The bool false parameter reflects the blkdev_issue_zeroout() API prior to commit ee472d835c26 ("block: add a flags argument to (__)blkdev_issue_zeroout") which was merged shortly before 2237498f0b5c.

2020-04-21scsi: qla2xxx: check UNLOADING before posting async workMartin Wilck
qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the completion of these async commands. If UNLOADING is set, this is doomed to timeout, because the async logout command will never complete. The only way to avoid waiting pointlessly is to fail posting these commands in the first place if the driver is in UNLOADING state. In general, posting any command should be avoided when the driver is UNLOADING. With this patch, "rmmod qla2xxx" completes without noticeable delay.

2020-04-21scsi: qla2xxx: set UNLOADING before waiting for session deletionMartin Wilck
The purpose of the UNLOADING flag is to avoid port login procedures to continue when a controller is in the process of shutting down. It makes sense to set this flag before starting session teardown. Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the test for UNLOADING is postponed until after the check for an already disabled PCI board.

2020-04-21scsi: core: Allow the state change from SDEV_QUIESCE to SDEV_BLOCKDexuan Cui
The APIs scsi_host_block()/scsi_host_unblock() were recently added by commit 2bb955840c1d ("scsi: core: add scsi_host_(block,unblock) helper function") and so far the APIs are only used by: commit 3d3ca53b1639 ("scsi: aacraid: use scsi_host_(block,unblock) to block I/O"). However, from reading the code, I think the APIs don't really work for aacraid, because, in the resume path of hibernation, when aac_suspend() -> scsi_host_block() is called, scsi_device_quiesce() has set the state to SDEV_QUIESCE, so aac_suspend() -> scsi_host_block() returns -EINVAL. Fix the issue by allowing the state change.

2020-04-21macvlan: fix null dereference in macvlan_device_event()Taehee Yoo
In the macvlan_device_event(), the list_first_entry_or_null() is used. This function could return null pointer if there is no node. But, the macvlan module doesn't check the null pointer. So, null-ptr-deref would occur. bond0 | +----+-----+ | | macvlan0 macvlan1 | | dummy0 dummy1 The problem scenario. If dummy1 is removed, 1. ->dellink() of dummy1 is called. 2. NETDEV_UNREGISTER of dummy1 notification is sent to macvlan module. 3. ->dellink() of macvlan1 is called. 4. NETDEV_UNREGISTER of macvlan1 notification is sent to bond module. 5. __bond_release_one() is called and it internally calls dev_set_mac_address(). 6. dev_set_mac_address() calls the ->ndo_set_mac_address() of macvlan1, which is macvlan_set_mac_address(). 7. macvlan_set_mac_address() calls the dev_set_mac_address() with dummy1. 8. NETDEV_CHANGEADDR of dummy1 is sent to macvlan module. 9. In the macvlan_device_event(), it calls list_first_entry_or_null(). At this point, dummy1 and macvlan1 were removed. So, list_first_entry_or_null() will return NULL. Test commands: ip netns add nst ip netns exec nst ip link add bond0 type bond for i in {0..10} do ip netns exec nst ip link add dummy$i type dummy ip netns exec nst ip link add macvlan$i link dummy$i \ type macvlan mode passthru ip netns exec nst ip link set macvlan$i master bond0 done ip netns del nst Splat looks like: [ 40.585687][ T146] general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] SMP DEI [ 40.587249][ T146] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] [ 40.588342][ T146] CPU: 1 PID: 146 Comm: kworker/u8:2 Not tainted 5.7.0-rc1+ #532 [ 40.589299][ T146] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 40.590469][ T146] Workqueue: netns cleanup_net [ 40.591045][ T146] RIP: 0010:macvlan_device_event+0x4e2/0x900 [macvlan] [ 40.591905][ T146] Code: 00 00 00 00 00 fc ff df 80 3c 06 00 0f 85 45 02 00 00 48 89 da 48 b8 00 00 00 00 00 fc ff d2 [ 40.594126][ T146] RSP: 0018:ffff88806116f4a0 EFLAGS: 00010246 [ 40.594783][ T146] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: 0000000000000000 [ 40.595653][ T146] RDX: 0000000000000000 RSI: ffff88806547ddd8 RDI: ffff8880540f1360 [ 40.596495][ T146] RBP: ffff88804011a808 R08: fffffbfff4fb8421 R09: fffffbfff4fb8421 [ 40.597377][ T146] R10: ffffffffa7dc2107 R11: 0000000000000000 R12: 0000000000000008 [ 40.598186][ T146] R13: ffff88804011a000 R14: ffff8880540f1000 R15: 1ffff1100c22de9a [ 40.599012][ T146] FS: 0000000000000000(0000) GS:ffff888067800000(0000) knlGS:0000000000000000 [ 40.600004][ T146] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 40.600665][ T146] CR2: 00005572d3a807b8 CR3: 000000005fcf4003 CR4: 00000000000606e0 [ 40.601485][ T146] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 40.602461][ T146] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 40.603443][ T146] Call Trace: [ 40.603871][ T146] ? nf_tables_dump_setelem+0xa0/0xa0 [nf_tables] [ 40.604587][ T146] ? macvlan_uninit+0x100/0x100 [macvlan] [ 40.605212][ T146] ? __module_text_address+0x13/0x140 [ 40.605842][ T146] notifier_call_chain+0x90/0x160 [ 40.606477][ T146] dev_set_mac_address+0x28e/0x3f0 [ 40.607117][ T146] ? netdev_notify_peers+0xc0/0xc0 [ 40.607762][ T146] ? __module_text_address+0x13/0x140 [ 40.608440][ T146] ? notifier_call_chain+0x90/0x160 [ 40.609097][ T146] ? dev_set_mac_address+0x1f0/0x3f0 [ 40.609758][ T146] dev_set_mac_address+0x1f0/0x3f0 [ 40.610402][ T146] ? __local_bh_enable_ip+0xe9/0x1b0 [ 40.611071][ T146] ? bond_hw_addr_flush+0x77/0x100 [bonding] [ 40.611823][ T146] ? netdev_notify_peers+0xc0/0xc0 [ 40.612461][ T146] ? bond_hw_addr_flush+0x77/0x100 [bonding] [ 40.613213][ T146] ? bond_hw_addr_flush+0x77/0x100 [bonding] [ 40.613963][ T146] ? __local_bh_enable_ip+0xe9/0x1b0 [ 40.614631][ T146] ? bond_time_in_interval.isra.31+0x90/0x90 [bonding] [ 40.615484][ T146] ? __bond_release_one+0x9f0/0x12c0 [bonding] [ 40.616230][ T146] __bond_release_one+0x9f0/0x12c0 [bonding] [ 40.616949][ T146] ? bond_enslave+0x47c0/0x47c0 [bonding] [ 40.617642][ T146] ? lock_downgrade+0x730/0x730 [ 40.618218][ T146] ? check_flags.part.42+0x450/0x450 [ 40.618850][ T146] ? __mutex_unlock_slowpath+0xd0/0x670 [ 40.619519][ T146] ? trace_hardirqs_on+0x30/0x180 [ 40.620117][ T146] ? wait_for_completion+0x250/0x250 [ 40.620754][ T146] bond_netdev_event+0x822/0x970 [bonding] [ 40.621460][ T146] ? __module_text_address+0x13/0x140 [ 40.622097][ T146] notifier_call_chain+0x90/0x160 [ 40.622806][ T146] rollback_registered_many+0x660/0xcf0 [ 40.623522][ T146] ? netif_set_real_num_tx_queues+0x780/0x780 [ 40.624290][ T146] ? notifier_call_chain+0x90/0x160 [ 40.624957][ T146] ? netdev_upper_dev_unlink+0x114/0x180 [ 40.625686][ T146] ? __netdev_adjacent_dev_unlink_neighbour+0x30/0x30 [ 40.626421][ T146] ? mutex_is_locked+0x13/0x50 [ 40.627016][ T146] ? unregister_netdevice_queue+0xf2/0x240 [ 40.627663][ T146] unregister_netdevice_many.part.134+0x13/0x1b0 [ 40.628362][ T146] default_device_exit_batch+0x2d9/0x390 [ 40.628987][ T146] ? unregister_netdevice_many+0x40/0x40 [ 40.629615][ T146] ? dev_change_net_namespace+0xcb0/0xcb0 [ 40.630279][ T146] ? prepare_to_wait_exclusive+0x2e0/0x2e0 [ 40.630943][ T146] ? ops_exit_list.isra.9+0x97/0x140 [ 40.631554][ T146] cleanup_net+0x441/0x890 [ ... ] Fixes: e289fd28176b ("macvlan: fix the problem when mac address changes for passthru mode") Reported-by: syzbot+5035b1f9dc7ea4558d5a@syzkaller.appspotmail.com Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.7 Quite a lot of fixes here, a lot of driver specific ones but the biggest one is the revert of changes to the startup and shutdown sequence for DAIs that went in during the merge window - they broke some older x86 platforms and attempts to fix them didn't succeed so it's safer to just roll them back and try to make sure those platforms are handled properly in any future attempt. The rockchip S/PDIF DT stuff was IIRC for validation issues.
2020-04-21ALSA: usb-audio: Apply async workaround for Scarlett 2i4 2nd genAlexander Tsoy
Due to rounding error driver sometimes incorrectly calculate next packet size, which results in audible clicks on devices with synchronous playback endpoints. For example on a high speed bus and a sample rate 44.1 kHz it loses one sample every ~40.9 seconds. Fortunately playback interface on Scarlett 2i4 2nd gen has a working explicit feedback endpoint, so we can switch playback data endpoint to asynchronous mode as a workaround.

2020-04-21tools/vm: fix cross-compile buildLucas Stach
Commit 7ed1c1901fe5 ("tools: fix cross-compile var clobbering") moved the setup of the CC variable to tools/scripts/Makefile.include to make the behavior consistent across all the tools Makefiles. As the vm tools missed the include we end up with the wrong CC in a cross-compiling evironment.
