2017-04-10phy: phy-mt65xx-usb3: add support for new version phyChunfeng Yun1-128/+218
There are some variations from mt2701 to mt2712: 1. banks shared by multiple ports are put back into each port, such as SPLLC and U2FREQ; 2. add a new bank MISC for u2port, and CHIP for u3port; 3. bank's offset in each port are also rearranged; Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

each port has its own reference clock, the HighSpeed port is 48M, and the SuperSpeed port is usually 26M, put them into port node for flexibility, this can close clock if the port is not used.

2017-04-10phy: phy-mt65xx-usb3: split SuperSpeed port into two onesChunfeng Yun1-74/+75
Currently usb3 port in fact includes two sub-ports, but it is not flexible for some cases, such as following one: usb3 port0 includes u2port0 and u3port0; usb2 port0 includes u2port1; If wants to support only HS, we can use u2port0 or u2port1, when select u2port0, u3port0 is not needed; If wants to support SS, we can compound u2port0 and u3port0, or u2port1 and u3port0, if select latter one, u2port0 is not needed. So it's more flexible to split usb3 port into two ones and also try best to save power by disabling unnecessary ports.

2017-04-10phy: rcar-gen3-usb2: fix implementation for runtime PMYoshihiro Shimoda1-7/+24
This patch fixes an issue that this driver doesn't take care of the runtime PM. This code assumed that devm_phy_create() called pm_runtime_enable(dev), but it misunderstood the dev_phy_create()'s specification. This driver should call its own pm_runtime_enable() before dev_phy_create().

2017-04-10phy: phy-exynos-pcie: make it explicitly non-modularPaul Gortmaker1-6/+2
The Kconfig currently controlling compilation of this code is: drivers/phy/Kconfig:config PHY_EXYNOS_PCIE drivers/phy/Kconfig: bool "Exynos PCIe PHY driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

Instead of adding separated driver & duplicating code we should work on improving existing (old) one.

2017-03-03netfilter: nf_tables: don't call nfnetlink_set_err() if nfnetlink_send() failsPablo Neira Ayuso2-81/+58
The underlying nlmsg_multicast() already sets sk->sk_err for us to notify socket overruns, so we should not do anything with this return value. So we just call nfnetlink_set_err() if: 1) We fail to allocate the netlink message. or 2) We don't have enough space in the netlink message to place attributes, which means that we likely need to allocate a larger message. Before this patch, the internal ESRCH netlink error code was propagated to userspace, which is quite misleading. Netlink semantics mandate that listeners just hit ENOBUFS if the socket buffer overruns.

2017-03-03netfilter: nft_set_rbtree: incorrect assumption on lower interval lookupsPablo Neira Ayuso1-5/+4
In case of adjacent ranges, we may indeed see either the high part of the range in first place or the low part of it. Remove this incorrect assumption, let's make sure we annotate the low part of the interval in case of we have adjacent interva intervals so we hit a matching in lookups.

2017-03-03netfilter: nf_conntrack_sip: fix wrong memory initialisationChristophe Leroy1-2/+0
In commit 82de0be6862cd ("netfilter: Add helper array register/unregister functions"), struct nf_conntrack_helper sip[MAX_PORTS][4] was changed to sip[MAX_PORTS * 4], so the memory init should have been changed to memset(&sip[4 * i], 0, 4 * sizeof(sip[i])); But as the sip[] table is allocated in the BSS, it is already set to 0 Fixes: 82de0be6862cd ("netfilter: Add helper array register/unregister functions") Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Fixes: 05ca5270005c can: gs_usb: add ethtool set_phys_id callback to locate physical device The gs_usb driver is performing USB transfers using buffers allocated on the stack. This causes the driver to not function with vmapped stacks. Instead, allocate memory for the transfer buffers.

2017-03-02smb2: Enforce sec= mount optionSachin Prabhu8-7/+49
If the security type specified using a mount option is not supported, the SMB2 session setup code changes the security type to RawNTLMSSP. We should instead fail the mount and return an error. The patch changes the code for SMB2 to make it similar to the code used for SMB1. Like in SMB1, we now use the global security flags to select the security method to be used when no security method is specified and to return an error when the requested auth method is not available. For SMB2, we also use ntlmv2 as a synonym for nltmssp.
