2016-11-24virtio: console: Unlock vqs while freeing buffersMatt Redfearn1-6/+16
commit 34563769e438d2881f62cf4d9badc4e589ac0ec0 upstream. Commit c6017e793b93 ("virtio: console: add locks around buffer removal in port unplug path") added locking around the freeing of buffers in the vq. However, when free_buf() is called with can_sleep = true and rproc is enabled, it calls dma_free_coherent() directly, requiring interrupts to be enabled. Currently a WARNING is triggered due to the spin locking around free_buf, with a call stack like this: WARNING: CPU: 3 PID: 121 at ./include/linux/dma-mapping.h:433 free_buf+0x1a8/0x288 Call Trace: [<8040c538>] show_stack+0x74/0xc0 [<80757240>] dump_stack+0xd0/0x110 [<80430d98>] __warn+0xfc/0x130 [<80430ee0>] warn_slowpath_null+0x2c/0x3c [<807e7c6c>] free_buf+0x1a8/0x288 [<807ea590>] remove_port_data+0x50/0xac [<807ea6a0>] unplug_port+0xb4/0x1bc [<807ea858>] virtcons_remove+0xb0/0xfc [<807b6734>] virtio_dev_remove+0x58/0xc0 [<807f918c>] __device_release_driver+0xac/0x134 [<807f924c>] device_release_driver+0x38/0x50 [<807f7edc>] bus_remove_device+0xfc/0x130 [<807f4b74>] device_del+0x17c/0x21c [<807f4c38>] device_unregister+0x24/0x38 [<807b6b50>] unregister_virtio_device+0x28/0x44 Fix this by restructuring the loops to allow the locks to only be taken where it is necessary to protect the vqs, and release it while the buffer is being freed.

2016-11-08hwrng: omap - Only fail if pm_runtime_get_sync returns < 0Dave Gerlach1-2/+2
commit ad8529fde9e3601180a839867a8ab041109aebb5 upstream. Currently omap-rng checks the return value of pm_runtime_get_sync and reports failure if anything is returned, however it should be checking if ret < 0 as pm_runtime_get_sync return 0 on success but also can return 1 if the device was already active which is not a failure case. Only values < 0 are actual failures.

2016-09-29x86/mm/pat, /dev/mem: Remove superfluous error messageJiri Kosina1-5/+1
commit 39380b80d72723282f0ea1d1bbf2294eae45013e upstream. Currently it's possible for broken (or malicious) userspace to flood a kernel log indefinitely with messages a-la Program dmidecode tried to access /dev/mem between f0000->100000 because range_is_allowed() is case of CONFIG_STRICT_DEVMEM being turned on dumps this information each and every time devmem_is_allowed() fails. Reportedly userspace that is able to trigger contignuous flow of these messages exists. It would be possible to rate limit this message, but that'd have a questionable value; the administrator wouldn't get information about all the failing accessess, so then the information would be both superfluous and incomplete at the same time :) Returning EPERM (which is what is actually happening) is enough indication for userspace what has happened; no need to log this particular error as some sort of special condition.

2016-02-15vTPM: fix memory allocation flag for rtce buffer at kernel bootHon Ching \(Vicky\) Lo1-1/+1
commit 60ecd86c4d985750efa0ea3d8610972b09951715 upstream. At ibm vtpm initialzation, tpm_ibmvtpm_probe() registers its interrupt handler, ibmvtpm_interrupt, which calls ibmvtpm_crq_process to allocate memory for rtce buffer. The current code uses 'GFP_KERNEL' as the type of kernel memory allocation, which resulted a warning at kernel/lockdep.c. This patch uses 'GFP_ATOMIC' instead so that the allocation is high-priority and does not sleep.

2015-04-09tpm/ibmvtpm: Additional LE support for tpm_ibmvtpm_sendjmlatten@linux.vnet.ibm.com2-8/+8
commit 62dfd912ab3b5405b6fe72d0135c37e9648071f1 upstream. Problem: When IMA and VTPM are both enabled in kernel config, kernel hangs during bootup on LE OS. Why?: IMA calls tpm_pcr_read() which results in tpm_ibmvtpm_send and tpm_ibmtpm_recv getting called. A trace showed that tpm_ibmtpm_recv was hanging. Resolution: tpm_ibmtpm_recv was hanging because tpm_ibmvtpm_send was sending CRQ message that probably did not make much sense to phype because of Endianness. The fix below sends correctly converted CRQ for LE. This was not caught before because it seems IMA is not enabled by default in kernel config and IMA exercises this particular code path in vtpm. Tested with IMA and VTPM enabled in kernel config and VTPM enabled on both a BE OS and a LE OS ppc64 lpar. This exercised CRQ and TPM command code paths in vtpm. Patch is against Peter's tpmdd tree on github which included Vicky's previous vtpm le patches.

commit 84eb186bc37c0900b53077ca21cf6dd15823a232 upstream. There was an oops in tpm_ibmvtpm_get_desired_dma, which caused kernel panic during boot when vTPM is enabled in Power partition configured in AMS mode. vio_bus_probe calls vio_cmo_bus_probe which calls tpm_ibmvtpm_get_desired_dma to get the size needed for DMA allocation. The problem is, vio_cmo_bus_probe is called before calling probe, which for vtpm is tpm_ibmvtpm_probe and it's this function that initializes and sets up vtpm's CRQ and gets required data values. Therefore, since this has not yet been done, NULL is returned in attempt to get the size for DMA allocation. We added a NULL check.

commit f07a5e9a331045e976a3d317ba43d14859d9407c upstream. Most device drivers do call 'tpm_do_selftest' which executes a TPM_ContinueSelfTest. tpm_i2c_stm_st33 is just pointlessly different, I think it is bug. These days we have the general assumption that the TPM is usable by the kernel immediately after the driver is finished, so we can no longer defer the mandatory self test to userspace.

commit 48e8ac2979920ffa39117e2d725afa3a749bfe8d upstream. With recent changes it is possible for the timer handler to detect an idle interface and not start the timer, but the thread to start an operation at the same time. The thread will not start the timer in that instance, resulting in the timer not running. Instead, move all timer operations under the lock and start the timer in the thread if it detect non-idle and the timer is not already running. Moving under locks allows the last timeout to be set in both the thread and the timer. 'Timer is not running' means that the timer is not pending and smi_timeout() is not running. So we need a flag to detect this correctly. Also fix a few other timeout bugs: setting the last timeout when the interrupt has to be disabled and the timer started, and setting the last timeout in check_start_timer_thread possibly racing with the timer Signed-off-by: Corey Minyard <cminyard@mvista.com> Signed-off-by: Bodo Stroesser <bstroesser@ts.fujitsu.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

commit 08d2d00b291ed4eb91530050274e67a761c1901d upstream. The loff_t type may be wider than phys_addr_t (e.g. on 32-bit systems). Consequently, the file offset may be truncated in the assignment. Currently, /dev/mem wraps around, which may cause applications to read or write incorrect regions of memory by accident. Let's follow POSIX file semantics here and return 0 when reading from and -EFBIG when writing to an offset that cannot be represented by a phys_addr_t. Note that the conditional is optimized out by the compiler if loff_t has the same size as phys_addr_t.

commit 5bbb2ae3d6f896f8d2082d1eceb6131c2420b7cf upstream. bind_get() checks the device number it is called with. It uses MAX_RAW_MINORS for the upper bound. But MAX_RAW_MINORS is set at compile time while the actual number of raw devices can be set at runtime. This means the test can either be too strict or too lenient. And if the test ends up being too lenient bind_get() might try to access memory beyond what was allocated for "raw_devices". So check against the runtime value (max_raw_minors) in this function.

If the user wishes to disable that they can set: xen_platform_pci=0 (in the guest config file) or xen_emul_unplug=never (on the Linux command line) except it does not work properly. The PV drivers still try to load and since the Xen platform driver is not run - and it has not initialized the grant tables, most of the PV drivers stumble upon: input: Xen Virtual Keyboard as /devices/virtual/input/input5 input: Xen Virtual Pointer as /devices/virtual/input/input6M ------------[ cut here ]------------ kernel BUG at /home/konrad/ssd/konrad/linux/drivers/xen/grant-table.c:1206! invalid opcode: 0000 [#1] SMP Modules linked in: xen_kbdfront(+) xenfs xen_privcmd CPU: 6 PID: 1389 Comm: modprobe Not tainted 3.13.0-rc1upstream-00021-ga6c892b-dirty #1 Hardware name: Xen HVM domU, BIOS 4.4-unstable 11/26/2013 RIP: 0010:[<ffffffff813ddc40>] [<ffffffff813ddc40>] get_free_entries+0x2e0/0x300 Call Trace: [<ffffffff8150d9a3>] ? evdev_connect+0x1e3/0x240 [<ffffffff813ddd0e>] gnttab_grant_foreign_access+0x2e/0x70 [<ffffffffa0010081>] xenkbd_connect_backend+0x41/0x290 [xen_kbdfront] [<ffffffffa0010a12>] xenkbd_probe+0x2f2/0x324 [xen_kbdfront] [<ffffffff813e5757>] xenbus_dev_probe+0x77/0x130 [<ffffffff813e7217>] xenbus_frontend_dev_probe+0x47/0x50 [<ffffffff8145e9a9>] driver_probe_device+0x89/0x230 [<ffffffff8145ebeb>] __driver_attach+0x9b/0xa0 [<ffffffff8145eb50>] ? driver_probe_device+0x230/0x230 [<ffffffff8145eb50>] ? driver_probe_device+0x230/0x230 [<ffffffff8145cf1c>] bus_for_each_dev+0x8c/0xb0 [<ffffffff8145e7d9>] driver_attach+0x19/0x20 [<ffffffff8145e260>] bus_add_driver+0x1a0/0x220 [<ffffffff8145f1ff>] driver_register+0x5f/0xf0 [<ffffffff813e55c5>] xenbus_register_driver_common+0x15/0x20 [<ffffffff813e76b3>] xenbus_register_frontend+0x23/0x40 [<ffffffffa0015000>] ? 0xffffffffa0014fff [<ffffffffa001502b>] xenkbd_init+0x2b/0x1000 [xen_kbdfront] [<ffffffff81002049>] do_one_initcall+0x49/0x170 .. snip.. which is hardly nice.

Ditto for the network one ('nics'). - (v2) if running in HVM, and if the user wanted 'xen_emul_unplug=unnecessary' then load block PV driver, and also setup the legacy IDE paths.

commit 85c5e0d451125c6ddb78663972e40af810b83644 upstream. The 'get_burstcount' function can in some circumstances 'return -EBUSY' which in tpm_stm_i2c_send is stored in an 'u32 burstcnt' thus converting the signed value into an unsigned value, resulting in 'burstcnt' being huge. Changing the type to u32 only does not solve the problem as the signed value is converted to an unsigned in I2C_WRITE_DATA, resulting in the same effect. Thus -> Change type of burstcnt to u32 (the return type of get_burstcount) -> Add a check for the return value of 'get_burstcount' and propagate a potential error. This makes also sense in the 'I2C_READ_DATA' case, where the there is no signed/unsigned conversion. found by coverity Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

For example, an architecture might have a rapidly changing register used to control random TLB cache eviction, or DRAM refresh that doesn't meet the requirements of get_cycles(), but which is good enough for the needs of the random driver.

The attribute was introduced in e2683957fb268c6b29316fd9e7191e13239a30a5 during the 3.12 merge window, so this patch needs to go in before 3.12 is released.
