2019-08-09USB: phy: twl6030: convert platform driver to use dev_groupsGreg Kroah-Hartman
Platform drivers now have the option to have the platform core create and remove any needed sysfs attribute files. So take advantage of that and do not register "by hand" any sysfs files.

2019-08-08net/tls: prevent skb_orphan() from leaking TLS plain text with offloadJakub Kicinski
sk_validate_xmit_skb() and drivers depend on the sk member of struct sk_buff to identify segments requiring encryption. Any operation which removes or does not preserve the original TLS socket such as skb_orphan() or skb_clone() will cause clear text leaks. Make the TCP socket underlying an offloaded TLS connection mark all skbs as decrypted, if TLS TX is in offload mode. Then in sk_validate_xmit_skb() catch skbs which have no socket (or a socket with no validation) and decrypted flag set. Note that CONFIG_SOCK_VALIDATE_XMIT, CONFIG_TLS_DEVICE and sk->sk_validate_xmit_skb are slightly interchangeable right now, they all imply TLS offload. The new checks are guarded by CONFIG_TLS_DEVICE because that's the option guarding the sk_buff->decrypted member. Second, smaller issue with orphaning is that it breaks the guarantee that packets will be delivered to device queues in-order. All TLS offload drivers depend on that scheduling property. This means skb_orphan_partial()'s trick of preserving partial socket references will cause issues in the drivers. We need a full orphan, and as a result netem delay/throttling will cause all TLS offload skbs to be dropped. Reusing the sk_buff->decrypted flag also protects from leaking clear text when incoming, decrypted skb is redirected (e.g. by TC). See commit 0608c69c9a80 ("bpf: sk_msg, sock{map|hash} redirect through ULP") for justification why the internal flag is safe. The only location which could leak the flag in is tcp_bpf_sendmsg(), which is taken care of by clearing the previously unused bit. v2: - remove superfluous decrypted mark copy (Willem); - remove the stale doc entry (Boris); - rely entirely on EOR marking to prevent coalescing (Boris); - use an internal sendpages flag instead of marking the socket (Boris). v3 (Willem): - reorganize the can_skb_orphan_partial() condition; - fix the flag leak-in through tcp_bpf_sendmsg.

2019-08-09usb: dwc2: gadget: Fix kill_all_requests raceJohn Keeping
When a gadget is disabled, kill_all_requests() can be called simultaneously from both a user process via dwc2_hsotg_pullup() and from the interrupt handler if the hardware detects disconnection. Since we drop the lock in dwc2_hsotg_complete_request() in order to call the completion handler, this means that the list is modified concurrently and leads to an infinite loop in kill_all_requests(). Replace the foreach loop with a while-not-empty loop in order to remove the danger of this concurrent modification.

2019-08-08inet: frags: re-introduce skb coalescing for local deliveryGuillaume Nault
Before commit d4289fcc9b16 ("net: IP6 defrag: use rbtrees for IPv6 defrag"), a netperf UDP_STREAM test[0] using big IPv6 datagrams (thus generating many fragments) and running over an IPsec tunnel, reported more than 6Gbps throughput. After that patch, the same test gets only 9Mbps when receiving on a be2net nic (driver can make a big difference here, for example, ixgbe doesn't seem to be affected). By reusing the IPv4 defragmentation code, IPv6 lost fragment coalescing (IPv4 fragment coalescing was dropped by commit 14fe22e33462 ("Revert "ipv4: use skb coalescing in defragmentation"")). Without fragment coalescing, be2net runs out of Rx ring entries and starts to drop frames (ethtool reports rx_drops_no_frags errors). Since the netperf traffic is only composed of UDP fragments, any lost packet prevents reassembly of the full datagram. Therefore, fragments which have no possibility to ever get reassembled pile up in the reassembly queue, until the memory accounting exeeds the threshold. At that point no fragment is accepted anymore, which effectively discards all netperf traffic. When reassembly timeout expires, some stale fragments are removed from the reassembly queue, so a few packets can be received, reassembled and delivered to the netperf receiver. But the nic still drops frames and soon the reassembly queue gets filled again with stale fragments. These long time frames where no datagram can be received explain why the performance drop is so significant. Re-introducing fragment coalescing is enough to get the initial performances again (6.6Gbps with be2net): driver doesn't drop frames anymore (no more rx_drops_no_frags errors) and the reassembly engine works at full speed. This patch is quite conservative and only coalesces skbs for local IPv4 and IPv6 delivery (in order to avoid changing skb geometry when forwarding). Coalescing could be extended in the future if need be, as more scenarios would probably benefit from it.

2019-08-08clk: samsung: exynos542x: Move MSCL subsystem clocks to its sub-CMUMarek Szyprowski
M2M scaler clocks require special handling of their parent bus clock during power domain on/off sequences. MSCL clocks were not initially added to the sub-CMU handler, because that time there was no driver for the M2M scaler device and it was not possible to test it. This patch fixes this issue. Parent clock for M2M scaler devices is now properly preserved during MSC power domain on/off sequence. This gives M2M scaler devices proper performance: fullHD XRGB32 image 1000 rotations test takes 3.17s instead of 45.08s.

2019-08-08clk: samsung: exynos5800: Move MAU subsystem clocks to MAU sub-CMUSylwester Nawrocki
This patch fixes broken sound on Exynos5422/5800 platforms after system/suspend resume cycle in cases where the audio root clock is derived from MAU_EPLL_CLK. In order to preserve state of the USER_MUX_MAU_EPLL_CLK clock mux during system suspend/resume cycle for Exynos5800 we group the MAU block input clocks in "MAU" sub-CMU and add the clock mux control bit to .suspend_regs. This ensures that user configuration of the mux is not lost after the PMU block changes the mux setting to OSC_DIV when switching off the MAU power domain. Adding the SRC_TOP9 register to exynos5800_clk_regs[] array is not sufficient as at the time of the syscore_ops suspend call MAU power domain is already turned off and we already save and subsequently restore an incorrect register's value.

This allows removal of clearing recovery bit on sq activate.

2019-08-08net/mlx5e: Fix false negative indication on tx reporter CQE recoveryAya Levin
Remove wrong error return value when SQ is not in error state. CQE recovery on TX reporter queries the sq state. If the sq is not in error state, the sq is either in ready or reset state. Ready state is good state which doesn't require recovery and reset state is a temporal state which ends in ready state. With this patch, CQE recovery in this scenario is successful.
