2020-01-25firestream: fix memory leaksWenwen Wang
In fs_open(), 'vcc' is allocated through kmalloc() and assigned to 'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g., there is no more free channel, an error code EBUSY or ENOMEM will be returned. However, 'vcc' is not deallocated, leading to memory leaks. Note that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated in fs_close(). But, if fs_open() fails, there is no guarantee that fs_close() will be invoked. To fix this issue, deallocate 'vcc' before the error code is returned. Signed-off-by: Wenwen Wang <wenwen@cs.uga.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-01-25net: cxgb3_main: Add CAP_NET_ADMIN check to CHELSIO_GET_MEMMichael Ellerman
The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in cxgb_extension_ioctl(). One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears to read memory directly out of the adapter and return it to userspace. It's not entirely clear what the contents of the adapter memory contains, but the assumption is that it shouldn't be accessible to all users. So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after the is_offload() check, which matches two of the other subcommands in the same function which also check for is_offload() and CAP_NET_ADMIN. Found by Ilja by code inspection, not tested as I don't have the required hardware.

2020-01-25hv_netvsc: Add XDP supportHaiyang Zhang
This patch adds support of XDP in native mode for hv_netvsc driver, and transparently sets the XDP program on the associated VF NIC as well. Setting / unsetting XDP program on synthetic NIC (netvsc) propagates to VF NIC automatically. Setting / unsetting XDP program on VF NIC directly is not recommended, also not propagated to synthetic NIC, and may be overwritten by setting of synthetic NIC. The Azure/Hyper-V synthetic NIC receive buffer doesn't provide headroom for XDP. We thought about re-use the RNDIS header space, but it's too small. So we decided to copy the packets to a page buffer for XDP. And, most of our VMs on Azure have Accelerated Network (SRIOV) enabled, so most of the packets run on VF NIC. The synthetic NIC is considered as a fallback data-path. So the data copy on netvsc won't impact performance significantly. XDP program cannot run with LRO (RSC) enabled, so you need to disable LRO before running XDP: ethtool -K eth0 lro off XDP actions not yet supported: XDP_REDIRECT Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S.

2020-01-24net/mlx5e: kTLS, Do not send decrypted-marked SKBs via non-accel pathTariq Toukan
When TCP out-of-order is identified (unexpected tcp seq mismatch), driver analyzes the packet and decides what handling should it get: 1. go to accelerated path (to be encrypted in HW), 2. go to regular xmit path (send w/o encryption), 3. drop. Packets marked with skb->decrypted by the TLS stack in the TX flow skips SW encryption, and rely on the HW offload. Verify that such packets are never sent un-encrypted on the wire. Add a WARN to catch such bugs, and prefer dropping the packet in these cases.

2020-01-24Bluetooth: btrtl: Use kvmalloc for FW allocationsMaxim Mikityanskiy
Currently, kmemdup is applied to the firmware data, and it invokes kmalloc under the hood. The firmware size and patch_length are big (more than PAGE_SIZE), and on some low-end systems (like ASUS E202SA) kmalloc may fail to allocate a contiguous chunk under high memory usage and fragmentation: Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821 Bluetooth: hci0: RTL: rom_version status=0 version=1 Bluetooth: hci0: RTL: loading rtl_bt/rtl8821a_fw.bin kworker/u9:2: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0 <stack trace follows> As firmware load happens on each resume, Bluetooth will stop working after several iterations, when the kernel fails to allocate an order-4 page. This patch replaces kmemdup with kvmalloc+memcpy. It's not required to have a contiguous chunk here, because it's not mapped to the device directly.

2020-01-24iommu/vt-d: Call __dmar_remove_one_dev_info with valid pointerJerry Snitselaar
It is possible for archdata.iommu to be set to DEFER_DEVICE_DOMAIN_INFO or DUMMY_DEVICE_DOMAIN_INFO so check for those values before calling __dmar_remove_one_dev_info. Without a check it can result in a null pointer dereference. This has been seen while booting a kdump kernel on an HP dl380 gen9.

2020-01-24mmc: core: Default to generic_cmd6_time as timeout in __mmc_switch()Ulf Hansson
All callers of __mmc_switch() should now be specifying a valid timeout for the CMD6 command. However, just to be sure, let's print a warning and default to use the generic_cmd6_time in case the provided timeout_ms argument is zero. In this context, let's also simplify some of the corresponding code and clarify some related comments.

2020-01-24mmc: block: Use generic_cmd6_time when modifying INAND_CMD38_ARG_EXT_CSDUlf Hansson
The INAND_CMD38_ARG_EXT_CSD is a vendor specific EXT_CSD register, which is used to prepare an erase/trim operation. However, it doesn't make sense to use a timeout of 10 minutes while updating the register, which becomes the case when the timeout_ms argument for mmc_switch() is set to zero. Instead, let's use the generic_cmd6_time, as that seems like a reasonable timeout to use for these cases.

2020-01-24mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMCUlf Hansson
The timeout values used while waiting for a CMD6 for BKOPS or a CACHE_FLUSH to complete, are not defined by the eMMC spec. However, a timeout of 10 minutes as is currently being used, is just silly for both of these cases. Instead, let's specify more reasonable timeouts, 120s for BKOPS and 30s for CACHE_FLUSH.

2020-01-24mmc: sdhci-cadence: remove unneeded 'inline' markerMasahiro Yamada
'static inline' in .c files does not make much sense because functions may or may not be inlined irrespective of the 'inline' marker. It is just a hint. This function is quite small, so very likely to be inlined by the compiler's optimization (-O2 or -Os), but it is up to the compiler after all.
