ec6931b | Will Deacon | 23 April 2014, 16:52:52 UTC | word-at-a-time: avoid undefined behaviour in zero_bytemask macro The asm-generic, big-endian version of zero_bytemask creates a mask of bytes preceding the first zero-byte by left shifting ~0ul based on the position of the first zero byte. Unfortunately, if the first (top) byte is zero, the output of prep_zero_mask has only the top bit set, resulting in undefined C behaviour as we shift left by an amount equal to the width of the type. As it happens, GCC doesn't manage to spot this through the call to fls(), but the issue remains if architectures choose to implement their shift instructions differently. An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in Xd == Xn. Rather than check explicitly for the problematic shift, this patch adds an extra shift by 1, replacing fls with __fls. Since zero_bytemask is never called with a zero argument (has_zero() is used to check the data first), we don't need to worry about calling __fls(0), which is undefined.

ac6c9e2 | Linus Torvalds | 27 April 2014, 22:08:12 UTC | Merge branch 'safe-dirty-tlb-flush' This merges the patch to fix possible loss of dirty bit on munmap() or madvice(DONTNEED). If there are concurrent writers on other CPU's that have the unmapped/unneeded page in their TLBs, their writes to the page could possibly get lost if a third CPU raced with the TLB flush and did a page_mkclean() before the page was fully written. Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another thread is still busy writing to it, you deserve all the lost writes you could get. But we kernel people hold ourselves to higher quality standards than "crazy people deserve to lose", because, well, we've seen people do all kinds of crazy things. So let's get it right, just because we can, and we don't have to worry about it. * safe-dirty-tlb-flush: mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts | 27 April 2014, 22:08:12 UTC |

Setting interrupt affinity to a not online cpu is prohibited and therefor the timer interrupt ends up on the wrong cpu, which leads to nasty complications. The SoC folks tried to hack around that in the SoC code in some more than nasty ways. The proper solution is to have a way to enforce the affinity setting to a not online cpu. The core patch to the genirq code provides that facility and the follow up patches make use of it in the GIC interrupt controller and the exynos timer driver. The change to the core code has no implications to existing users, except for the rename of the locked function and therefor the necessary fixup in mips/cavium. Aside of that, no runtime impact is possible, as none of the existing interrupt chips implements anything which depends on the force argument of the irq_set_affinity() callback" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource: Exynos_mct: Register clock event after request_irq() clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup irqchip: Gic: Support forced affinity setting genirq: Allow forcing cpu affinity of interrupts | 27 April 2014, 18:21:03 UTC |

cfd4a53 | Chris Mason | 26 April 2014, 12:02:03 UTC | Btrfs: limit the path size in send to PATH_MAX fs_path_ensure_buf is used to make sure our path buffers for send are big enough for the path names as we construct them. The buffer size is limited to 32K by the length field in the struct. But bugs in the path construction can end up trying to build a huge buffer, and we'll do invalid memmmoves when the buffer length field wraps. This patch is step one, preventing the overflows.

1cf35d4 | Linus Torvalds | 25 April 2014, 23:05:40 UTC | mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts The mmu-gather operation 'tlb_flush_mmu()' has done two things: the actual tlb flush operation, and the batched freeing of the pages that the TLB entries pointed at. This splits the operation into separate phases, so that the forced batched flushing done by zap_pte_range() can now do the actual TLB flush while still holding the page table lock, but delay the batched freeing of all the pages to after the lock has been dropped. This in turn allows us to avoid a race condition between set_page_dirty() (as called by zap_pte_range() when it finds a dirty shared memory pte) and page_mkclean(): because we now flush all the dirty page data from the TLB's while holding the pte lock, page_mkclean() will be held up walking the (recently cleaned) page tables until after the TLB entries have been flushed from all CPU's.

The intention was just dropping "if (ops->mmap)" check as the control won't reach the point if the mmap callback isn't implemented, but I mistakenly removed the error return check together with it. This led to Xorg crash on i810 which was reported and bisected to the commit and then to the specific change by Tobias.

Because it is possible that kernfs_link_sibling() couldn't find a suitable slot and bail out, this leads to a mismatch between elevated subdir count with actual children node numbers.

c09ec25 | Denis Turischev | 25 April 2014, 16:20:14 UTC | xhci: Switch Intel Lynx Point ports to EHCI on shutdown. The same issue like with Panther Point chipsets. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS have work around for this, but not all. One example is Compulab's mini-desktop, the Intense-PC2. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. This patch should be backported to stable kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell" Signed-off-by: Denis Turischev <denis@compulab.co.il> Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> | 25 April 2014, 16:34:10 UTC |
1f81b6d | Julius Werner | 25 April 2014, 16:20:13 UTC | usb: xhci: Prefer endpoint context dequeue pointer over stopped_trb We have observed a rare cycle state desync bug after Set TR Dequeue Pointer commands on Intel LynxPoint xHCs (resulting in an endpoint that doesn't fetch new TRBs and thus an unresponsive USB device). It always triggers when a previous Set TR Dequeue Pointer command has set the pointer to the final Link TRB of a segment, and then another URB gets enqueued and cancelled again before it can be completed. Further investigation showed that the xHC had returned the Link TRB in the TRB Pointer field of the Transfer Event (CC == Stopped -- Length Invalid), but when xhci_find_new_dequeue_state() later accesses the Endpoint Context's TR Dequeue Pointer field it is set to the first TRB of the next segment. The driver expects those two values to be the same in this situation, and uses the cycle state of the latter together with the address of the former. This should be fine according to the XHCI specification, since the endpoint ring should be stopped when returning the Transfer Event and thus should not advance over the Link TRB before it gets restarted. However, real-world XHCI implementations apparently don't really care that much about these details, so the driver should follow a more defensive approach to try to work around HC spec violations. This patch removes the stopped_trb variable that had been used to store the TRB Pointer from the last Transfer Event of a stopped TRB. Instead, xhci_find_new_dequeue_state() now relies only on the Endpoint Context, requiring a small amount of additional processing to find the virtual address corresponding to the TR Dequeue Pointer. Some other parts of the function were slightly rearranged to better fit into this model. This patch should be backported to kernels as old as 2.6.31 that contain the commit ae636747146ea97efa18e04576acd3416e2514f5 "USB: xhci: URB cancellation support."

Unfortunately, this in turn broke Marvell Armada 370/XP, both comprising Marvell PJ4B CPUs without iWMMXt extension. Instead of only checking for cpuid, which may not be sufficient to determine iWMMXt support, the presence of iWMMXt coprocessors can be checked by enabling and reading the Coprocessor ID register (wCID, register 0 of CP1). Therefore this adds an explicit check for the presence and correct wCID value, before enabling iWMMXt capabilities. As a bonus, also print the iWMMXt version of a detected coprocessor.

7deb39e | Thomas Pfaff | 23 April 2014, 10:33:22 UTC | serial_core: fix uart PORT_UNKNOWN handling While porting a RS485 driver from 2.6.29 to 3.14, i noticed that the serial tty driver could break it by using uart ports that it does not own : 1. uart_change_pm ist called during uart_open and calls the uart pm function without checking for PORT_UNKNOWN. The fix is to move uart_change_pm from uart_open to uart_port_startup. 2. The return code from the uart request_port call in uart_set_info is not handled properly, leading to the situation that the serial driver also thinks it owns the uart ports. This can triggered by doing following actions : setserial /dev/ttyS0 uart none # release the uart ports modprobe lirc-serial # or any other device that uses the uart setserial /dev/ttyS0 uart 16550 # gives no error and the uart tty driver # can use the ports as well Signed-off-by: Thomas Pfaff <tpfaff@pcs.com> Reviewed-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> | 24 April 2014, 22:38:22 UTC |

bb7f09b | Doug Anderson | 21 April 2014, 16:40:34 UTC | serial: samsung: Use the passed in "port", fixing kgdb w/ no console The two functions in the samsung serial driver used for writing characters out to the port were inconsistent about whether they used the passed in "port" or the global "cons_uart". There was no reason to use the global and the use of the global in s3c24xx_serial_put_poll_char() caused a crash in the case where you used the serial port for kgdboc but not for console. Fix it so we used the passed in variable. Note that this doesn't fix all problems with the samsung serial driver. Specifically: * s3c24xx_serial_console_putchar() is still 99% identical to s3c24xx_serial_put_poll_char() (the function signature is different, but that's about it). A future patch will make them slightly less identical and judging by other serial drivers we may need yet more differences eventually. * The samsung serial driver still doesn't allow you to have more than one console port since it still uses the global cons_uart in s3c24xx_serial_console_write().

6a20dbd | Manfred Schlaegl | 08 April 2014, 12:42:04 UTC | tty: Fix race condition between __tty_buffer_request_room and flush_to_ldisc The race was introduced while development of linux-3.11 by e8437d7ecbc50198705331449367d401ebb3181f and e9975fdec0138f1b2a85b9624e41660abd9865d4. Originally it was found and reproduced on linux-3.12.15 and linux-3.12.15-rt25, by sending 500 byte blocks with 115kbaud to the target uart in a loop with 100 milliseconds delay. In short: 1. The consumer flush_to_ldisc is on to remove the head tty_buffer. 2. The producer adds a number of bytes, so that a new tty_buffer must be allocated and added by __tty_buffer_request_room. 3. The consumer removes the head tty_buffer element, without handling newly committed data. Detailed example: * Initial buffer: * Head, Tail -> 0: used=250; commit=250; read=240; next=NULL * Consumer: ''flush_to_ldisc'' * consumed 10 Byte * buffer: * Head, Tail -> 0: used=250; commit=250; read=250; next=NULL {{{ count = head->commit - head->read; // count = 0 if (!count) { // enter // INTERRUPTED BY PRODUCER -> if (head->next == NULL) break; buf->head = head->next; tty_buffer_free(port, head); continue; } }}} * Producer: tty_insert_flip_... 10 bytes + tty_flip_buffer_push * buffer: * Head, Tail -> 0: used=250; commit=250; read=250; next=NULL * added 6 bytes: head-element filled to maximum. * buffer: * Head, Tail -> 0: used=256; commit=250; read=250; next=NULL * added 4 bytes: __tty_buffer_request_room is called * buffer: * Head -> 0: used=256; commit=256; read=250; next=1 * Tail -> 1: used=4; commit=0; read=250 next=NULL * push (tty_flip_buffer_push) * buffer: * Head -> 0: used=256; commit=256; read=250; next=1 * Tail -> 1: used=4; commit=4; read=250 next=NULL * Consumer {{{ count = head->commit - head->read; if (!count) { // INTERRUPTED BY PRODUCER <- if (head->next == NULL) // -> no break break; buf->head = head->next; tty_buffer_free(port, head); // ERROR: tty_buffer head freed -> 6 bytes lost continue; } }}} This patch reintroduces a spin_lock to protect this case. Perhaps later a lock-less solution could be found.

10164c2 | Johan Hovold | 23 April 2014, 09:32:19 UTC | USB: serial: fix sysfs-attribute removal deadlock Fix driver new_id sysfs-attribute removal deadlock by making sure to not hold any locks that the attribute operations grab when removing the attribute. Specifically, usb_serial_deregister holds the table mutex when deregistering the driver, which includes removing the new_id attribute. This can lead to a deadlock as writing to new_id increments the attribute's active count before trying to grab the same mutex in usb_serial_probe. The deadlock can easily be triggered by inserting a sleep in usb_serial_deregister and writing the id of an unbound device to new_id during module unload. As the table mutex (in this case) is used to prevent subdriver unload during probe, it should be sufficient to only hold the lock while manipulating the usb-serial driver list during deregister. A racing probe will then either fail to find a matching subdriver or fail to get the corresponding module reference.

cd84f00 | Peter Chen | 24 April 2014, 00:15:27 UTC | usb: chipidea: coordinate usb phy initialization for different phy type For internal PHY (like UTMI), the phy clock may from internal pll, it is on/off on the fly, the access PORTSC.PTS will hang without phy clock. So, the usb_phy_init which will open phy clock needs to be called before hw_phymode_configure. See: http://marc.info/?l=linux-arm-kernel&m=139350618732108&w=2 For external PHY (like ulpi), it needs to configure portsc.pts before visit viewport, or the viewport can't be visited. so phy_phymode_configure needs to be called before usb_phy_init. See: cd0b42c2a6d2a74244f0053f8960f5dad5842278 It may not the best solution, but it can work for all situations.

Most fixes are MUSB which learned to remove its debugfs directories properly, got a fix for PHY handling and now knows that it should make sure its clocks aren't gated before trying to access registers. ffs got a race fix between ffs_epfile_io() and ffs_func_eps_disable(). dwc3 got a fix for system suspend/resume and now only iterates over valid endpoints when trying to resize TX fifos. usb_get_phy() now will properly return an error if try_module_get() fails.

Used jiffies-based timeout, while jiffies are not running at this stage of system shutdown (therefore a config transaction error - if happened - would have never be reported).

cb171f7 | Bjorn Helgaas | 23 April 2014, 16:21:06 UTC | PNP: Work around BIOS defects in Intel MCH area reporting Work around BIOSes that don't report the entire Intel MCH area. MCHBAR is not an architected PCI BAR, so MCH space is usually reported as a PNP0C02 resource. The MCH space was once 16KB, but is 32KB in newer parts. Some BIOSes still report a PNP0C02 resource that is only 16KB, which means the rest of the MCH space is consumed but unreported. This can cause resource map sanity check warnings or (theoretically) a device conflict if we assigned the unreported space to another device. The Intel perf event uncore driver tripped over this when it claimed the MCH region: resource map sanity check conflict: 0xfed10000 0xfed15fff 0xfed10000 0xfed13fff pnp 00:01 Info: mapping multiple BARs. Your kernel is fine. To prevent this, if we find a PNP0C02 resource that covers part of the MCH space, extend it to cover the entire space.

2704f80 | H Hartley Sweeten | 28 March 2014, 16:20:58 UTC | staging: comedi: usbdux: bug fix for accessing 'ao_chanlist' in private data In usbdux_ao_cmd(), the channels for the command are transfered from the cmd->chanlist and stored in the private data 'ao_chanlist'. The channel numbers are bit-shifted when stored so that they become the "command" that is transfered to the device. The channel to command conversion results in the 'ao_chanlist' having these values for the channels: channel 0 -> ao_chanlist = 0x00 channel 1 -> ao_chanlist = 0x40 channel 2 -> ao_chanlist = 0x80 channel 3 -> ao_chanlist = 0xc0 The problem is, the usbduxsub_ao_isoc_irq() function uses the 'chan' value from 'ao_chanlist' to access the 'ao_readback' array in the private data. So instead of accessing the array as 0, 1, 2, 3, it accesses it as 0x00, 0x40, 0x80, 0xc0. Fix this by storing the raw channel number in 'ao_chanlist' and doing the bit-shift when creating the command.
