Commit 8e961870 removed the FREEZE/THAW handling in xfs_compat_ioctl but never added any compat handler back, so now any freeze/thaw request from a 32-bit binary ond 64-bit userspace will fail. As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL entries in fs/compat_ioctl.c will do the job. Signed-off-by:

David Howells authored
free_uid() and free_user_ns() are corecursive when CONFIG_USER_SCHED=n, but free_user_ns() is called from free_uid() by way of uid_hash_remove(), which requires uidhash_lock to be held. free_user_ns() then calls free_uid() to complete the destruction. Fix this by deferring the destruction of the user_namespace. Signed-off-by:

Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO count in musb_host_tx() risks sending a short packet prematurely for transfer sizes over 64 KB. Similarly, although data transfer size shouldn't exceed 65535 bytes for the control endpoint, making musb_h_ep0_continue() more robust WRT URBs with possibly oversized buffer will not hurt either...

For some strange reason the host side musb_giveback() decides that it's always got an IN transfer when the hardware endpoint is using a shared FIFO. This causes musb_save_toggle() to read the toggle state from the RXCSR register instead of TXCSR, and may also cause unneeded reloading of RX endpoint registers. Signed-off-by:

Sergei Shtylyov authored
The musb_h_disable() routine can oops in some cases: - It's not safe to read hep->hcpriv outside musb->lock, since it gets changed on completion IRQ paths. - The list iterators aren't safe to use in that way; just remove the first element while !list_empty(), so deletions on other code paths can't make trouble. We need two "scrub the list" loops because only one branch should touch hardware and advance the schedule.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the control or bulk schedules when the URB being cancelled is the only one queued to its endpoint. That will cause musb_advance_schedule() to block once it reaches 'struct musb_qh' with now empty URB list, so URBs queued for other endpoints after the one being dequeued will not be served. Fix by unlinking the QH from the list except when it's already being handled (typically by musb_giveback). Since a QH with an empty URB list is now supposed to be freed, do that. And remove a now-useless check from musb_advance_schedule(). [ dbrownell@users.sourceforge.net: update patch description, and fold in a dequeue() comment patch ] Signed-off-by:

The input queue should be used for TX on endpoints which share FIFO hardware. The host TX path wasn't doing that. Shared FIFOs are most often configured for periodic endpoints, which are mostly used for RX/IN transfers ... that's probably how this bug managed to linger for a long time.

Now that the musb build fixes for DaVinci got merged (RC3?), kick in the other bits needed to get it finally *working* in mainline: - Use clk_enable()/clk_disable() ... the "always enable USB clocks" code this originally relied on has since been removed. - Initialize the USB device only after the relevant I2C GPIOs are available, so the host side can properly enable VBUS. - Tweak init sequencing to cope with mainline's relatively late init of the I2C system bus for power switches, transceivers, and so on. Sanity tested on DM6664 EVM for host and peripheral modes; that system won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also verified on OMAP3. (Unrelated: correct the MODULE_PARM_DESC spelling of musb_debug.) Signed-off-by:

This patch (as1218) fixes a problem with a radio-control joystick used in the "walkera 4#3" helicopter. This device responds to the initial Get-String-Descriptor request for string 0 (which is really the list of supported languages) by sending its config descriptor! The usb_get_string() routine needs to check whether it got the right type of descriptor. Oddly enough, this sort of check is already present in usb_get_descriptor(). The patch changes the error code from -EPROTO to -ENODATA, because -EPROTO shows up in so many other contexts to indicate a hardware failure rather than a firmware error. Signed-off-by:
