commit 01b8cedf upstream. Currently compress driver hardcodes direction as playback to get substream from the stream. This results in getting the incorrect substream for compressed capture usecase. To fix this, remove the hardcoding and derive substream based on the stream direction. Signed-off-by:

commit 440aeca4 upstream. The functions igb_read_phy_reg_gs40g/igb_write_phy_reg_gs40g (which were removed in 2a3cdead) explicitly selected the required page at every phy_reg access. Currently, igb_get_phy_id_82575 relays on the fact that page 0 is already selected. The assumption is not fulfilled for my Lex 3I380CW motherboard with integrated dual i211 based gigabit ethernet. This leads to igb initialization failure and network interfaces are not working: igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k igb: Copyright (c) 2007-2014 Intel Corporation. igb: probe of 0000:01:00.0 failed with error -2 igb: probe of 0000:02:00.0 failed with error -2 In order to fix it, we explicitly select page 0 before first access to phy registers.

commit b7f8a09f upstream. When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit set, DIR1 is expected to have SGID bit set (and owning group equal to the owning group of 'DIR0'). However when 'DIR0' also has some default ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on 'DIR1' to get cleared if user is not member of the owning group. Fix the problem by moving posix_acl_update_mode() out of __btrfs_set_acl() into btrfs_set_acl(). That way the function will not be called when inheriting ACLs which is what we want as it prevents SGID bit clearing and the mode has been properly set by posix_acl_create() anyway.

commit 4a4274bf upstream. In the stable linux-3.16 branch, I ran into a warning in the wlcore driver: drivers/net/wireless/ti/wlcore/spi.c: In function 'wl12xx_spi_raw_write': drivers/net/wireless/ti/wlcore/spi.c:315:1: error: the frame size of 12848 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] Newer kernels no longer show the warning, but the bug is still there, as the allocation is based on the CPU page size rather than the actual capabilities of the hardware. This replaces the PAGE_SIZE macro with the SZ_4K macro, i.e. 4096 bytes per buffer. Signed-off-by:

commit 622b7a47 upstream. The decoder will try to use branch packets to find an IP to start decoding or to recover from errors. Currently the FUP packet is used only in the case of an overflow, however there is no reason for that to be a special case. So just use FUP always when scanning for an IP. Signed-off-by:

commit f952eace upstream. Intel PT uses IP compression based on the last IP. For decoding purposes, 'last IP' is not updated when a branch target has been suppressed, which is indicated by IPBytes == 0. IPBytes is stored in the packet 'count', so ensure never to set 'last_ip' when packet 'count' is zero. Signed-off-by:

commit ee14ac0e upstream. Intel PT uses IP compression based on the last IP. For decoding purposes, 'last IP' is considered to be reset to zero whenever there is a synchronization packet (PSB). The decoder wasn't doing that, and was treating the zero value to mean that there was no last IP, whereas compression can be done against the zero value. Fix by setting last_ip to zero when a PSB is received and keep track of have_last_ip. Signed-off-by:

commit f6a5885f upstream. Verify that the caller-provided sockaddr structure is large enough to contain the sa_family field, before accessing it in bind() handlers of the AF_NFC socket. Since the syscall doesn't enforce a minimum size of the corresponding memory region, very short sockaddrs (zero or one byte long) result in operating on uninitialized memory while referencing .sa_family.

commit 608c4adf upstream. Fix the sockaddr length verification in the connect() handler of NFC/LLCP sockets, to compare against the size of the actual structure expected on input (sockaddr_nfc_llcp) instead of its shorter version (sockaddr_nfc). Both structures are defined in include/uapi/linux/nfc.h. The fields specific to the _llcp extended struct are as follows: 276 __u8 dsap; /* Destination SAP, if known */ 277 __u8 ssap; /* Source SAP to be bound to */ 278 char service_name[NFC_LLCP_MAX_SERVICE_NAME]; /* Service name URI */; 279 size_t service_name_len; If the caller doesn't provide a sufficiently long sockaddr buffer, these fields remain uninitialized (and they currently originate from the stack frame of the top-level sys_connect handler). They are then copied by llcp_sock_connect() into internal storage (nfc_llcp_sock structure), and could be subsequently read back through the user-mode getsockname() function (handled by llcp_sock_getname()). This would result in the disclosure of up to ~70 uninitialized bytes from the kernel stack to user-mode clients capable of creating AFC_NFC sockets. Signed-off-by:

commit 45dd39b9 upstream. The nci-device was never deregistered in the event that fw-initialisation failed. Fix this by moving the firmware initialisation before device registration since the firmware work queue should be available before registering. Note that this depends on a recent fix that moved device-name initialisation back to to nci_allocate_device() as the firmware-workqueue name is now derived from the nfc-device name.

commit e5834ac2 upstream. Use the nfc- rather than phy-device in firmware-management code that needs a valid struct device. This specifically fixes a NULL-pointer dereference in nfcmrvl_fw_dnld_init() during registration when the underlying tty is one end of a Unix98 pty. Note that the driver still uses the phy device for any debugging, which is fine for now.

commit 0cbe4011 upstream. This specifically fixes resource leaks in the registration error paths. Device-managed resources is a bad fit for this driver as devices can be registered from the n_nci line discipline. Firstly, a tty may not even have a corresponding device (should it be part of a Unix98 pty) something which would lead to a NULL-pointer dereference when registering resources. Secondly, if the tty has a class device, its lifetime exceeds that of the line discipline, which means that resources would leak every time the line discipline is closed (or if registration fails). Currently, the devres interface was only being used to request a reset gpio despite the fact that it was already explicitly freed in nfcmrvl_nci_unregister_dev() (along with the private data), something which also prevented the resource leak at close. Note that the driver treats gpio number 0 as invalid despite it being perfectly valid. This will be addressed in a follow-up patch.

commit 20777bc5 upstream. Commit 7eda8b8e ("NFC: Use IDR library to assing NFC devices IDs") moved device-id allocation and struct-device initialisation from nfc_allocate_device() to nfc_register_device(). This broke just about every nfc-device-registration error path, which continue to call nfc_free_device() that tries to put the device reference of the now uninitialised (but zeroed) struct device: kobject: '(null)' (ce316420): is not initialized, yet kobject_put() is being called. The late struct-device initialisation also meant that various work queues whose names are derived from the nfc device name were also misnamed: 421 root 0 SW< [(null)_nci_cmd_] 422 root 0 SW< [(null)_nci_rx_w] 423 root 0 SW< [(null)_nci_tx_w] Move the id-allocation and struct-device initialisation back to nfc_allocate_device() and fix up the single call site which did not use nfc_free_device() in its error path.

commit 07246c11 upstream. The bug was triggered when do suspend/resuming continuously on Dell XPS L322X/0PJHXN version 9333 (2013) with kernel 4.12.0-041200rc4-generic. But can't reproduce on DELL E5440 + AR9300 PCIE chips. The warning is caused by accessing invalid pointer sc->rng_task. sc->rng_task is not be cleared after kthread_stop(sc->rng_task) be called in ath9k_rng_stop(). Because the kthread is stopped before ath9k_rng_kthread() be scheduled. So set sc->rng_task to null after kthread_stop(sc->rng_task) to resolve this issue.

commit cf8ce1ea upstream. One scenario that could lead to UAF is two threads writing simultaneously to the "tx99" debug file. One of them would set the "start" value to true and follow to ath9k_tx99_init(). Inside the function it would set the sc->tx99_state to true after allocating sc->tx99skb. Then, the other thread would execute write_file_tx99() and call ath9k_tx99_deinit(). sc->tx99_state would be freed. After that, the first thread would continue inside ath9k_tx99_init() and call r = ath9k_tx99_send(sc, sc->tx99_skb, &txctl); that would make use of the freed sc->tx99_skb memory. Signed-off-by:

commit c592fafb upstream. The thermal child device reuses the parent MFD-device device-tree node when registering a thermal zone, but did not take a reference to the node. This leads to a reference imbalance, and potential use-after-free, when the node reference is dropped by the platform-bus device destructor (once for the child and later again for the parent). Fix this by dropping any reference already held to a device-tree node and getting a reference to the parent's node which will be balanced on reprobe or on platform-device release, whichever comes first. Note that simply clearing the of_node pointer on probe errors and on driver unbind would not allow the use of device-managed resources as specifically thermal_zone_of_sensor_unregister() claims that a valid device-tree node pointer is needed during deregistration (even if it currently does not seem to use it).

commit bd664f6b upstream. I made the mistake of upgrading my desktop to the new Fedora 26 that comes with gcc-7.1.1. There's nothing wrong per se that I've noticed, but I now have 1500 lines of warnings, mostly from the new format-truncation warning triggering all over the tree. We use 'snprintf()' and friends in a lot of places, and often know that the numbers are fairly small (ie a controller index or similar), but gcc doesn't know that, and sees an 'int', and thinks that it could be some huge number. And then complains when our buffers are not able to fit the name for the ten millionth controller. These warnings aren't necessarily bad per se, and we probably want to look through them subsystem by subsystem, but at least during the merge window they just mean that I can't even see if somebody is introducing any *real* problems when I pull. So warnings disabled for now. Signed-off-by:

commit a8b6fda3 upstream. The MSR permission bitmaps are shared by all VMs. However, some VMs may not be configured to support MPX, even when the host does. If the host supports VMX and the guest does not, we should intercept accesses to the BNDCFGS MSR, so that we can synthesize a #GP fault. Furthermore, if the host does not support MPX and the "ignore_msrs" kvm kernel parameter is set, then we should intercept accesses to the BNDCFGS MSR, so that we can skip over the rdmsr/wrmsr without raising a #GP fault.

commit ea0212f4 upstream. The wakeirq infrastructure uses RCU to protect the list of wakeirqs. That breaks the irq bus locking infrastructure, which is allows sleeping functions to be called so interrupt controllers behind slow busses, e.g. i2c, can be handled. The wakeirq functions hold rcu_read_lock and call into irq functions, which in case of interrupts using the irq bus locking will trigger a might_sleep() splat. Convert the wakeirq infrastructure to Sleepable RCU and unbreak it. Fixes: 4990d4fe (PM / Wakeirq: Add automated device wake IRQ handling) Reported-by:

commit 73bb059f upstream. The point of sched_group_mask is to select those CPUs from sched_group_cpus that can actually arrive at this balance domain. The current code gets it wrong, as can be readily demonstrated with a topology like: node 0 1 2 3 0: 10 20 30 20 1: 20 10 20 30 2: 30 20 10 20 3: 20 30 20 10 Where (for example) domain 1 on CPU1 ends up with a mask that includes CPU0: [] CPU1 attaching sched-domain: [] domain 0: span 0-2 level NUMA [] groups: 1 (mask: 1), 2, 0 [] domain 1: span 0-3 level NUMA [] groups: 0-2 (mask: 0-2) (cpu_capacity: 3072), 0,2-3 (cpu_capacity: 3072) This causes sched_balance_cpu() to compute the wrong CPU and consequently should_we_balance() will terminate early resulting in missed load-balance opportunities. The fixed topology looks like: [] CPU1 attaching sched-domain: [] domain 0: span 0-2 level NUMA [] groups: 1 (mask: 1), 2, 0 [] domain 1: span 0-3 level NUMA [] groups: 0-2 (mask: 1) (cpu_capacity: 3072), 0,2-3 (cpu_capacity: 3072) (note: this relies on OVERLAP domains to always have children, this is true because the regular topology domains are still here -- this is before degenerate trimming) Debugged-by:
