2016-10-24usb: increase ohci watchdog delay to 275 msecBryan Paluch1-1/+1
Increase ohci watchout delay to 275 ms. Previous delay was 250 ms with 20 ms of slack, after removing slack time some ohci controllers don't respond in time.

2016-10-24usb: musb: Fix hardirq-safe hardirq-unsafe lock order errorTony Lindgren1-5/+2
If we configure musb with 2430 glue as a peripheral, and then rmmod omap2430 module, we'll get the following error: [ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ] ... rmmod/413 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire: (&phy->mutex){+.+.+.}, at: [<c04b9fd0>] phy_power_off+0x1c/0xb8 [ 204.678710] and this task is already holding: (&(&musb->lock)->rlock){-.-...}, at: [<bf3a482c>] musb_gadget_stop+0x24/0xec [musb_hdrc] which would create a new lock dependency: (&(&musb->lock)->rlock){-.-...} -> (&phy->mutex){+.+.+.} ... This is because some glue layers expect musb_platform_enable/disable to be called with spinlock held, and 2430 glue layer has USB PHY on the I2C bus using a mutex. We could fix the glue layers to take the spinlock, but we still have a problem of musb_plaform_enable/disable being called in an unbalanced manner. So that would still lead into USB PHY enable/disable related problems for omap2430 glue layer. While it makes sense to only enable USB PHY when needed from PM point of view, in this case we just can't do it yet without breaking things. So let's just revert phy_enable/disable related changes instead and reconsider this after we have fixed musb_platform_enable/disable to be balanced.

A device in this state can be identified in resume if its link state is in polling or compliance mode, and the current connect status is 0. A device in this state needs to be warm reset. Intel 100/c230 series PCH specification update Doc #332692-006 Errata #8 Observed on Cherryview and Apollolake as they go into compliance mode if LFPS times out during polling, and re-plugged devices are not discovered at resume.

This reverts commit aa381a7259c3 ("usb: dwc2: gadget: fix TX FIFO size and address initialization"). The original commit removed the FIFO size programming per endpoint. The DPTXFSIZn register is also used for DIEPTXFn and the SIZE field is r/w in dedicated fifo mode. So it isn't appropriate to simply remove this initialization as it might break existing behavior. Also, some cores might not have enough fifo space to handle the programming method used in the reverted patch, resulting in fifo initialization failure.

2016-10-14pkeys: Remove easily triggered WARNDave Jones1-1/+0
This easy-to-trigger warning shows up instantly when running Trinity on a kernel with CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS disabled. At most this should have been a printk, but the -EINVAL alone should be more than adequate indicator that something isn't available.

2016-10-14ovl: use vfs_get_link()Miklos Szeredi2-49/+7
Resulting in a complete removal of a function basically implementing the inverse of vfs_readlink(). As a bonus, now the proper security hook is also called. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2016-10-14vfs: add vfs_get_link() helperMiklos Szeredi2-0/+26
This helper is for filesystems that want to read the symlink and are better off with the get_link() interface (returning a char *) rather than the readlink() interface (copy into a userspace buffer). Also call the LSM hook for readlink (not get_link) since this is for symlink reading not following. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2016-10-14ovl: use generic_readlinkMiklos Szeredi1-20/+1
All filesystems that are backers for overlayfs would also use generic_readlink(). Move this logic to the overlay itself, which is a nice cleanup. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

2016-10-13CIFS: Reset read oplock to NONE if we have mandatory locks after reopenPavel Shilovsky1-0/+9
We are already doing the same thing for an ordinary open case: we can't keep read oplock on a file if we have mandatory byte-range locks because pagereading can conflict with these locks on a server. Fix it by setting oplock level to NONE. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <smfrench@gmail.com>
2016-10-13CIFS: Fix persistent handles re-opening on reconnectPavel Shilovsky2-5/+18
openFileList of tcon can be changed while cifs_reopen_file() is called that can lead to an unexpected behavior when we return to the loop. Fix this by introducing a temp list for keeping all file handles that need to be reopen. Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <smfrench@gmail.com>
