Commit 468bcc2a ("usb: musb: dsps: kill OTG timer on suspend") stopped the timer in suspend path but forgot the re-enable it in the resume path. This patch fixes the behaviour. Cc: <stable@vger.kernel.org> # v3.14+ Fixes 468bcc2a "usb: musb: dsps: kill OTG timer on suspend" Signed-off-by:

A request allocated from e.g. ep1out cannot be queued to any other endpoint. This bug has been in f_loopback at least since mid-2011 and since nobody has really screamed about it, we're not backporting to any stable kernels. Debugged with MUSB since that's the only controller which complains about this case. Signed-off-by:

The commit '2e4c7553 usb: gadget: f_fs: add aio support' broke the quirk implemented to align buffer size to maxpacketsize on out endpoint. As result, functionfs does not work on Intel platforms using dwc3 driver (i.e. Bay Trail and Merrifield). This patch fixes the issue. This code is based on a previous Qiuxu's patch.

During FunctionFS bind, ffs_data_get() function was called twice (in functionfs_bind() and in ffs_do_functionfs_bind()), while on unbind ffs_data_put() was called once (in functionfs_unbind() function). In result refcount never reached value 0, and ffs memory resources has been never released. Since ffs_data_get() call in ffs_do_functionfs_bind() is redundant and not neccessary, we remove it to have equal number of gets ans puts, and free allocated memory after refcount reach 0.

This reverts commit 02dae36a. That commit is bogus in two ways: 1) There's no way dwc3-omap's ->suspend() can cause any effect on xhci's ->suspend(). Linux device driver model guarantees that a parent's ->suspend() will only be called after all children are suspended. dwc3-omap is the parent of the parent of xhci. 2) When implementing Deep Sleep states where context is lost, USBOTGSS_IRQ0 register, well, looses context so we _must_ rewrite it otherwise core IRQs will never be reenabled and USB will appear to be dead.

commit c58d80f5 ("usb: musb: Ensure that cppi41 timer gets armed on premature DMA TX irq") fixed hrtimer scheduling bug. There is one left which does not trigger that often. The following scenario is still possible: lock(&x->lock); hrtimer_start(&x->t); unlock(&x->lock); expires: t->function(); lock(&x->lock); lock(&x->lock); if (!hrtimer_queued(&x->t)) hrtimer_start(&x->t); unlock(&x->lock); if (!list_empty(x->early_tx_list)) ret = HRTIMER_RESTART; -> hrtimer_forward_now(...) } else ret = HRTIMER_NORESTART; unlock(&x->lock); and the timer callback returns HRTIMER_RESTART for an armed timer. This is wrong and we run into the BUG_ON() in __run_hrtimer(). This can happens on SMP or PREEMPT-RT. The patch fixes the problem by only starting the timer if the timer is not yet queued.

According to Section 8.5.3.2 of the USB 2.0 specification, a USB device must terminate a Data Phase with either a short packet or a ZLP (if the previous transfer was a multiple of wMaxPacketSize). For reference, here's what the USB 2.0 specification, section 8.5.3.2 says: " 8.5.3.2 Variable-length Data Stage A control pipe may have a variable-length data phase in which the host requests more data than is contained in the specified data structure. When all of the data structure is returned to the host, the function should indicate that the Data stage is ended by returning a packet that is shorter than the MaxPacketSize for the pipe. If the data structure is an exact multiple of wMaxPacketSize for the pipe, the function will return a zero-length packet to indicate the end of the Data stage. " Signed-off-by:

if our list of requests is empty, return early. There's really nothing to be done in case our request list is empty anyway because the only situation where we our list is empty, is when we're transferring ZLPs. Signed-off-by:

On USB20CV's Interface Descriptor Test, a series of SetInterface/GetInterface requests are issued and gadget driver is required to always return correct alternate setting. In one step of the test, g_serial with f_obex was returning the wrong value (1 instead of 0). In order to fix this, we will now hold currently selected alternate setting inside our struct f_obex and just return that from our ->get_alt() implementation. Note that his also simplifies the code a bit. Signed-off-by:

If a set_alt() to the same alternate setting that's already selected is received, functions are required to reset the interface state, this means we must disable all endpoints and reenable them again. This is also documented on our kdoc for struct usb_function * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may * initialize usb_ep.driver data at this time (when it is used). * Note that setting an interface to its current altsetting resets * interface state, and that all interfaces have a disabled state.

The way trace works is that it won't decode strings until we read the actual trace. Because of that, we can't make assumptions of pointers still being valid at the time we read the trace.

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static. Really minor stuff" * git://git.infradead.org/users/eparis/audit: (31 commits) audit: rename audit_log_remove_rule to disambiguate for trees audit: cull redundancy in audit_rule_change audit: WARN if audit_rule_change called illegally audit: put rule existence check in canonical order next: openrisc: Fix build audit: get comm using lock to avoid race in string printing audit: remove open_arg() function that is never used audit: correct AUDIT_GET_FEATURE return message type audit: set nlmsg_len for multicast messages. audit: use union for audit_field values since they are mutually exclusive audit: invalid op= values for rules audit: use atomic_t to simplify audit_serial() kernel/audit.c: use ARRAY_SIZE instead of sizeof/sizeof[0] audit: reduce scope of audit_log_fcaps audit: reduce scope of audit_net_id audit: arm64: Remove the audit arch argument to audit_syscall_entry arm64: audit: Add audit hook in syscall_trace_enter/exit() audit: x86: drop arch from __audit_syscall_entry() interface sparc: implement is_32bit_task sparc: properly conditionalize use of TIF_32BIT ...
