commit 1ac0cb5d upstream. do_anonymous_page() has been wrong to dirty the pte regardless. If it's not going to mark the pte writable, then it won't help to mark it dirty here, and clogs up memory with pages which will need swap instead of being thrown away. Especially wrong if no overcommit is chosen, and this vma is not yet VM_ACCOUNTed - we could exceed the limit and OOM despite no overcommit. Signed-off-by:

commit 408e82b7 upstream. Hiroaki Wakabayashi points out that when mlock() has been interrupted by SIGKILL, the subsequent munlock() takes unnecessarily long because its use of __get_user_pages() insists on faulting in all the pages which mlock() never reached. It's worse than slowness if mlock() is terminated by Out Of Memory kill: the munlock_vma_pages_all() in exit_mmap() insists on faulting in all the pages which mlock() could not find memory for; so innocent bystanders are killed too, and perhaps the system hangs. __get_user_pages() does a lot that's silly for munlock(): so remove the munlock option from __mlock_vma_pages_range(), and use a simple loop of follow_page()s in munlock_vma_pages_range() instead; ignoring absent pages, and not marking present pages as accessed or dirty. (Change munlock() to only go so far as mlock() reached? That does not work out, given the convention that mlock() claims complete success even when it has to give up early - in part so that an underlying file can be extended later, and those pages locked which earlier would give SIGBUS.)

commit 78986a67 upstream. After anti-fragmentation was merged, a bug was reported whereby devices that depended on high-order atomic allocations were failing. The solution was to preserve a property in the buddy allocator which tended to keep the minimum number of free pages in the zone at the lower physical addresses and contiguous. To preserve this property, MIGRATE_RESERVE was introduced and a number of pageblocks at the start of a zone would be marked "reserve", the number of which depended on min_free_kbytes. Anti-fragmentation works by avoiding the mixing of page migratetypes within the same pageblock. One way of helping this is to increase min_free_kbytes because it becomes less like that it will be necessary to place pages of of MIGRATE_RESERVE is unbounded, the free memory is kept there in large contiguous blocks instead of helping anti-fragmentation as much as it should. With the page-allocator tracepoint patches applied, it was found during anti-fragmentation tests that the number of fragmentation-related events were far higher than expected even with min_free_kbytes at higher values. This patch limits the number of MIGRATE_RESERVE blocks that exist per zone to two. For example, with a sufficient min_free_kbytes, 4MB of memory will be kept aside on an x86-64 and remain more or less free and contiguous for the systems uptime. This should be sufficient for devices depending on high-order atomic allocations while helping fragmentation control when min_free_kbytes is tuned appropriately. As side-effect of this patch is that the reserve variable is converted to int as unsigned long was the wrong type to use when ensuring that only the required number of reserve blocks are created. With the patches applied, fragmentation-related events as measured by the page allocator tracepoints were significantly reduced when running some fragmentation stress-tests on systems with min_free_kbytes tuned to a value appropriate for hugepage allocations at runtime. On x86, the events recorded were reduced by 99.8%, on x86-64 by 99.72% and on ppc64 by 99.83%. Signed-off-by:

Not upstream as it is fixed differently in .32 I noticed that alloc_bootmem_huge_page() will only advance to the next node on failure to allocate a huge page. I asked about this on linux-mm and linux-numa, cc'ing the usual huge page suspects. Mel Gorman responded: I strongly suspect that the same node being used until allocation failure instead of round-robin is an oversight and not deliberate at all. It appears to be a side-effect of a fix made way back in commit 63b4613c ["hugetlb: fix hugepage allocation with memoryless nodes"]. Prior to that patch it looked like allocations would always round-robin even when allocation was successful. Andy Whitcroft countered that the existing behavior looked like Andi Kleen's original implementation and suggested that we ask him. We did and Andy replied that his intention was to interleave the allocations. So, ... This patch moves the advance of the hstate next node from which to allocate up before the test for success of the attempted allocation. This will unconditionally advance the next node from which to alloc, interleaving successful allocations over the nodes with sufficient contiguous memory, and skipping over nodes that fail the huge page allocation attempt. Note that alloc_bootmem_huge_page() will only be called for huge pages of order > MAX_ORDER. Signed-off-by:

commit 624defa1 upstream. Interrupt transfers are submitted to the xHCI hardware using the same TRB type as bulk transfers. Re-use the bulk transfer enqueueing code to enqueue interrupt transfers. Interrupt transfers are a bit different than bulk transfers. When the interrupt endpoint is to be serviced, the xHC will consume (at most) one TD. A TD (comprised of sg list entries) can take several service intervals to transmit. The important thing for device drivers to note is that if they use the scatter gather interface to submit interrupt requests, they will not get data sent from two different scatter gather lists in the same service interval. For now, the xHCI driver will use the service interval from the endpoint's descriptor (bInterval). Drivers will need a hook to poll at a more frequent interval. Set urb->interval to the interval that the xHCI hardware will use. Signed-off-by:

commit 2f697f6c upstream. The xHCI hardware reports the number of bytes untransferred for a given transfer buffer. If the hardware reports a bytes untransferred value greater than the submitted buffer size, we want to play it safe and say no data was transferred.

commit 99eb32db upstream. Make sure that the amount of data the xHC says was transmitted is less than or equal to the size of the requested transfer buffer.

commit 83fbcdcc upstream. The 0.95 xHCI spec says that non-control endpoints will be halted if a babble is detected on a transfer. The 0.96 xHCI spec says all types of endpoints will be halted when a babble is detected. Some hardware that claims to be 0.95 compliant halts the control endpoint anyway. When a babble is detected on a control endpoint, check the hardware's output endpoint context to see if the endpoint is marked as halted. If the control endpoint is halted, a reset endpoint command must be issued and the transfer ring dequeue pointer needs to be moved past the stopped transfer. Basically, we treat it as if the control endpoint had stalled. Handle bulk babbling endpoints as if we got a completion event with a stall completion code. Signed-off-by:

commit ac9d8fe7 upstream. This Fresco Logic xHCI host controller chip revision puts bad data into the output endpoint context after a Reset Endpoint command. It needs a Configure Endpoint command (instead of a Set TR Dequeue Pointer command) after the reset endpoint command. Set up the input context before issuing the Reset Endpoint command so we don't copy bad data from the output endpoint context. The HW also can't handle two commands queued at once, so submit the TRB for the Configure Endpoint command in the event handler for the Reset Endpoint command. Devices that stall on control endpoints before a configuration is selected will not work under this Fresco Logic xHCI host controller revision. This patch is for prototype hardware that will be given to other companies for evaluation purposes only, and should not reach consumer hands. Fresco Logic's next chip rev should have this bug fixed.

commit 82d1009f upstream. When a control endpoint stalls, the next control transfer will clear the stall. The USB core doesn't call down to the host controller driver's endpoint_reset() method when control endpoints stall, so the xHCI driver has to do all its stall handling for internal state in its interrupt handler. When the host stalls on a control endpoint, it may stop on the data phase or status phase of the control transfer. Like other stalled endpoints, the xHCI driver needs to queue a Reset Endpoint command and move the hardware's control endpoint ring dequeue pointer past the failed control transfer (with a Set TR Dequeue Pointer or a Configure Endpoint command). Since the USB core doesn't call usb_hcd_reset_endpoint() for control endpoints, we need to do this in interrupt context when we get notified of the stalled transfer. URBs may be queued to the hardware before these two commands complete. The endpoint queue will be restarted once both commands complete. Signed-off-by:

commit 2d3f1fac upstream. Full speed devices have varying max packet sizes (8, 16, 32, or 64) for endpoint 0. The xHCI hardware needs to know the real max packet size that the USB core discovers after it fetches the first 8 bytes of the device descriptor. In order to fix this without adding a new hook to host controller drivers, the xHCI driver looks for an updated max packet size for control endpoints. If it finds an updated size, it issues an evaluate context command and waits for that command to finish. This should only happen in the initialization and device descriptor fetching steps in the khubd thread, so blocking should be fine. Signed-off-by:

commit 47aded8a upstream. Set the max packet size for the default control endpoint on high speed devices to be 64 bytes. High speed devices always have a max packet size of 64 bytes. There's no use setting it to eight for the initial 8 byte descriptor fetch and then issuing (and waiting for) an evaluate context command to update it to 64 bytes for the subsequent control transfers. The USB core guesses that the max packet size on a full speed control endpoint is 64 bytes, and then updates it after the first 8-byte descriptor fetch. Change the initial setup for the xHCI internal representation of the full speed device to have a 64 byte max packet size. Signed-off-by:

commit b0567b3f upstream. Different sections of the xHCI 0.95 specification had opposing requirements for the chain bit in a link transaction request buffer (TRB). The chain bit is used to designate that adjacent TRBs are all part of the same scatter gather list that should be sent to the device. Link TRBs can be in the middle, or at the beginning or end of these chained TRBs. Sections 4.11.5.1 and 6.4.4.1 both stated the link TRB "shall have the chain bit set to 1", meaning it is always chained to the next TRB. However, section 4.6.9 on the stop endpoint command has specific cases for what the hardware must do for a link TRB with the chain bit set to 0. The 0.96 specification errata later cleared up this issue by fixing the 4.11.5.1 and 6.4.4.1 sections to state that a link TRB can have the chain bit set to 1 or 0. The problem is that the xHCI cancellation code depends on the chain bit of the link TRB being cleared when it's at the end of a TD, and some 0.95 xHCI hardware simply stops processing the ring when it encounters a link TRB with the chain bit cleared. Allow users who are testing 0.95 xHCI prototypes to set a module parameter (link_quirk) to turn on this link TRB work around. Cancellation may not work if the ring is stopped exactly on a link TRB with chain bit set, but cancellation should be a relatively uncommon case. Signed-off-by:

commit 7bd032dc upstream. This patch (as1292) modifies the USB serial console driver, to make it compatible with the recent changes to the USB serial core. The most important change is that serial->disc_mutex now has to be unlocked following a successful call to usb_serial_get_by_index(). Other less notable changes include: Use the requested port number instead of port 0 always. Prevent the serial device from being autosuspended. Use the ASYNCB_INITIALIZED flag bit to indicate when the port hardware has been initialized. In spite of these changes, there's no question that the USB serial console code is still a big hack.

commit 320348c8 upstream. This patch (as1291) removes a bunch of code from serial_open(), things that were rendered unnecessary by earlier patches. A missing spinlock is added to protect port->port.count, which needs to be incremented even if the open fails but not if the tty has gotten a hangup. The test for whether the hardware has been initialized, based on the use count, is replaced by a more transparent test of the ASYNCB_INITIALIZED bit in the port flags. Signed-off-by:

commit ff8324df upstream. This patch (as1290) adds some missing tests. serial_down() isn't supposed to do anything if the hardware hasn't been initialized, and serial_close() isn't supposed to do anything if the tty has gotten a hangup (because serial_hangup() takes care of shutting down the hardware).

commit cc56cd01 upstream. This patch (as1287) makes serial_install() be reponsible for acquiring references to the usb_serial structure and the driver module when a tty is first used. This is more sensible than having serial_open() do it, because a tty can be opened many times whereas it is installed only once, when it is created. (Not to mention that these actions are reversed when the tty is released, not when it is closed.) Finally, it is at install time that the TTY core takes its own reference to the usb_serial module, so it is only fitting that we should act the same way in regard to the lower-level serial driver.

commit 8bc2c1b2 upstream. This patch (as1286) changes usb_serial_get_by_index(). Now the routine will check whether the serial device has been disconnected; if it has then the return value will be NULL. If the device hasn't been disconnected then the routine will return with serial->disc_mutex held, so that the caller can use the structure without fear of racing against driver unloads. This permits the scope of table_mutex in destroy_serial() to be reduced. Instead of protecting the entire function, it suffices to protect the part that actually uses serial_table[], i.e., the call to return_serial(). There's no longer any danger of the refcount being incremented after it reaches 0 (which was the reason for having the large scope previously), because it can't reach 0 until the serial device has been disconnected. Also, the patch makes serial_install() check that serial is non-NULL before attempting to use it. Signed-off-by:

commit 41bd34dd upstream. This patch (as1284) changes the referencing of the usb_serial and usb_serial_port structures in usb-serial.c. It's not feasible to make the port structures keep a reference to the serial structure, because the ports need to remain in existence when serial is released -- quite a few of the drivers expect this. Consequently taking a reference to the port when the device file is open is insufficient; such a reference would not pin serial. To fix this, we now take a reference to serial when the device file is opened. The final put_device() for the ports occurs in destroy_serial(), so that the ports will last as long as they are needed. The patch initializes all the port devices, including those in the unused "fake" ports. This makes the code more uniform because they can all be released in the same way. The error handling code in usb_serial_probe() is much simplified by this approach; instead of freeing everything by hand we can use a single usb_serial_put() call. Also simplified is the port-release mechanism. Instead of being two separate routines, port_release() and port_free() can be combined into one. Signed-off-by:

commit 2023c610 upstream. This patch (as1271) affects when new devices get linked into their bus's list of devices. Currently this happens after probing, and it doesn't happen at all if probing fails. Clearly this is wrong, because at that point quite a few symbolic links have already been created in sysfs. We are committed to adding the device, so it should be linked into the bus's list regardless. In addition, this needs to happen before the uevent announcing the new device gets issued. Otherwise user programs might try to access the device before it has been added to the bus. To fix both these problems, the patch moves the call to klist_add_tail() forward from bus_attach_device() to bus_add_device(). Since bus_attach_device() now does nothing but probe for drivers, it has been renamed to bus_probe_device(). And lastly, the kerneldoc is updated. Signed-off-by:
