2019-08-01xen/swiotlb: fix condition for calling xen_destroy_contiguous_region()Juergen Gross
The condition in xen_swiotlb_free_coherent() for deciding whether to call xen_destroy_contiguous_region() is wrong: in case the region to be freed is not contiguous calling xen_destroy_contiguous_region() is the wrong thing to do: it would result in inconsistent mappings of multiple PFNs to the same MFN. This will lead to various strange crashes or data corruption. Instead of calling xen_destroy_contiguous_region() in that case a warning should be issued as that situation should never occur.

2019-07-31selinux: fix memory leak in policydb_init()Ondrej Mosnacek
Since roles_init() adds some entries to the role hash table, we need to destroy also its keys/values on error, otherwise we get a memory leak in the error path.

2019-07-31drm/msm: Use the correct dma_sync calls in msm_gemRob Clark
[subject was: drm/msm: shake fist angrily at dma-mapping] So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but it falls appart with dma direct ops. The problem is that, depending on display generation, we can have either set of dma ops (mdp4 and dpu have iommu wired to mdss node, which maps to toplevel drm device, but mdp5 has iommu wired up to the mdp sub-node within mdss). Fixes this splat on mdp5 devices: Unable to handle kernel paging request at virtual address ffffffff80000000 Mem abort info: ESR = 0x96000144 Exception class = DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000144 CM = 1, WnR = 1 swapper pgtable: 4k pages, 48-bit VAs, pgdp=00000000810e4000 [ffffffff80000000] pgd=0000000000000000 Internal error: Oops: 96000144 [#1] SMP Modules linked in: btqcomsmd btqca bluetooth cfg80211 ecdh_generic ecc rfkill libarc4 panel_simple msm wcnss_ctrl qrtr_smd drm_kms_helper venus_enc venus_dec videobuf2_dma_sg videobuf2_memops drm venus_core ipv6 qrtr qcom_wcnss_pil v4l2_mem2mem qcom_sysmon videobuf2_v4l2 qmi_helpers videobuf2_common crct10dif_ce mdt_loader qcom_common videodev qcom_glink_smem remoteproc bmc150_accel_i2c bmc150_magn_i2c bmc150_accel_core bmc150_magn snd_soc_lpass_apq8016 snd_soc_msm8916_analog mms114 mc nf_defrag_ipv6 snd_soc_lpass_cpu snd_soc_apq8016_sbc industrialio_triggered_buffer kfifo_buf snd_soc_lpass_platform snd_soc_msm8916_digital drm_panel_orientation_quirks CPU: 2 PID: 33 Comm: kworker/2:1 Not tainted 5.3.0-rc2 #1 Hardware name: Samsung Galaxy A5U (EUR) (DT) Workqueue: events deferred_probe_work_func pstate: 80000005 (Nzcv daif -PAN -UAO) pc : __clean_dcache_area_poc+0x20/0x38 lr : arch_sync_dma_for_device+0x28/0x30 sp : ffff0000115736a0 x29: ffff0000115736a0 x28: 0000000000000001 x27: ffff800074830800 x26: ffff000011478000 x25: 0000000000000000 x24: 0000000000000001 x23: ffff000011478a98 x22: ffff800009fd1c10 x21: 0000000000000001 x20: ffff800075ad0a00 x19: 0000000000000000 x18: ffff0000112b2000 x17: 0000000000000000 x16: 0000000000000000 x15: 00000000fffffff0 x14: ffff000011455d70 x13: 0000000000000000 x12: 0000000000000028 x11: 0000000000000001 x10: ffff00001106c000 x9 : ffff7e0001d6b380 x8 : 0000000000001000 x7 : ffff7e0001d6b380 x6 : ffff7e0001d6b382 x5 : 0000000000000000 x4 : 0000000000001000 x3 : 000000000000003f x2 : 0000000000000040 x1 : ffffffff80001000 x0 : ffffffff80000000 Call trace: __clean_dcache_area_poc+0x20/0x38 dma_direct_sync_sg_for_device+0xb8/0xe8 get_pages+0x22c/0x250 [msm] msm_gem_get_and_pin_iova+0xdc/0x168 [msm] ...

2019-07-31Bluetooth: hci_uart: check for missing tty operationsVladis Dronov
Certain ttys operations (pty_unix98_ops) lack tiocmget() and tiocmset() functions which are called by the certain HCI UART protocols (hci_ath, hci_bcm, hci_intel, hci_mrvl, hci_qca) via hci_uart_set_flow_control() or directly. This leads to an execution at NULL and can be triggered by an unprivileged user. Fix this by adding a helper function and a check for the missing tty operations in the protocols code. This fixes CVE-2019-10207. The Fixes: lines list commits where calls to tiocm[gs]et() or hci_uart_set_flow_control() were added to the HCI UART protocols.

2019-07-31mm: slub: Fix slab walking for init_on_freeLaura Abbott
To properly clear the slab on free with slab_want_init_on_free, we walk the list of free objects using get_freepointer/set_freepointer. The value we get from get_freepointer may not be valid. This isn't an issue since an actual value will get written later but this means there's a chance of triggering a bug if we use this value with set_freepointer: kernel BUG at mm/slub.c:306! invalid opcode: 0000 [#1] PREEMPT PTI CPU: 0 PID: 0 Comm: swapper Not tainted 5.2.0-05754-g6471384a #4 RIP: 0010:kfree+0x58a/0x5c0 Code: 48 83 05 78 37 51 02 01 0f 0b 48 83 05 7e 37 51 02 01 48 83 05 7e 37 51 02 01 48 83 05 7e 37 51 02 01 48 83 05 d6 37 51 02 01 <0f> 0b 48 83 05 d4 37 51 02 01 48 83 05 d4 37 51 02 01 48 83 05 d4 RSP: 0000:ffffffff82603d90 EFLAGS: 00010002 RAX: ffff8c3976c04320 RBX: ffff8c3976c04300 RCX: 0000000000000000 RDX: ffff8c3976c04300 RSI: 0000000000000000 RDI: ffff8c3976c04320 RBP: ffffffff82603db8 R08: 0000000000000000 R09: 0000000000000000 R10: ffff8c3976c04320 R11: ffffffff8289e1e0 R12: ffffd52cc8db0100 R13: ffff8c3976c01a00 R14: ffffffff810f10d4 R15: ffff8c3976c04300 FS: 0000000000000000(0000) GS:ffffffff8266b000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff8c397ffff000 CR3: 0000000125020000 CR4: 00000000000406b0 Call Trace: apply_wqattrs_prepare+0x154/0x280 apply_workqueue_attrs_locked+0x4e/0xe0 apply_workqueue_attrs+0x36/0x60 alloc_workqueue+0x25a/0x6d0 workqueue_init_early+0x246/0x348 start_kernel+0x3c7/0x7ec x86_64_start_reservations+0x40/0x49 x86_64_start_kernel+0xda/0xe4 secondary_startup_64+0xb6/0xc0 Modules linked in: ---[ end trace f67eb9af4d8d492b ]--- Fix this by ensuring the value we set with set_freepointer is either NULL or another value in the chain.

2019-07-31arm64: cpufeature: Fix feature comparison for CTR_EL0.{CWG,ERG}Will Deacon
If CTR_EL0.{CWG,ERG} are 0b0000 then they must be interpreted to have their architecturally maximum values, which defeats the use of FTR_HIGHER_SAFE when sanitising CPU ID registers on heterogeneous machines. Introduce FTR_HIGHER_OR_ZERO_SAFE so that these fields effectively saturate at zero.
