This has the side-effect of making the FIQ thrash because the hardware will generate multiple instances of a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the associated interrupts. Additionally, on non-split transactions make sure that only unmasked interrupts are cleared. This caused a hard-to-trigger but serious race condition when you had the combination of an endpoint awaiting error recovery and a transaction completed on an endpoint - due to the sequencing and timing of interrupts generated by the dwc_otg core, it was possible to confuse the IRQ handler. | 30 November 2013, 16:42:09 UTC |
| a58fb16 | P33M | 13 July 2013, 19:41:26 UTC | dwc_otg: mask correct interrupts after transaction error recovery The dwc_otg driver will unmask certain interrupts on a transaction that previously halted in the error state in order to reset the QTD error count. The various fine-grained interrupt handlers do not consider that other interrupts besides themselves were unmasked. By disabling the two other interrupts only ever enabled in DMA mode for this purpose, we can avoid unnecessary function calls in the IRQ handler. This will also prevent an unneccesary FIQ interrupt from being generated if the FIQ is enabled. | 30 November 2013, 16:42:08 UTC |

Calling it asynchronously in the tasklet was not safe (regression in c4564d4a1a0a9b10d4419e48239f5d99e88d2667). This change unlinks it from the endpoint prior to queueing it for handling in the tasklet, and also adds a check to ensure the urb is OK to be unlinked before doing so. NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb when a USB device was unplugged/replugged during data transfer. This effect was reproduced using automated USB port power control, hundreds of replug events were performed during active transfers to confirm that the problem was eliminated. | 30 November 2013, 16:42:00 UTC |

For now busylooping only. IRQ support might be added later. With non-overclocked Raspberry Pi, the performance is ~360 MB/s for simple copy or ~260 MB/s for two-pass copy (used when dragging windows to the right). In the case of using DMA channel 0, the performance improves to ~440 MB/s. For comparison, VFP optimized CPU copy can only do ~114 MB/s in the same conditions (hindered by reading uncached source buffer).

| 8bda66c | Harm Hanemaaijer | 20 June 2013, 18:21:39 UTC | Speed up console framebuffer imageblit function Especially on platforms with a slower CPU but a relatively high framebuffer fill bandwidth, like current ARM devices, the existing console monochrome imageblit function used to draw console text is suboptimal for common pixel depths such as 16bpp and 32bpp. The existing code is quite general and can deal with several pixel depths. By creating special case functions for 16bpp and 32bpp, by far the most common pixel formats used on modern systems, a significant speed-up is attained which can be readily felt on ARM-based devices like the Raspberry Pi and the Allwinner platform, but should help any platform using the fb layer. The special case functions allow constant folding, eliminating a number of instructions including divide operations, and allow the use of an unrolled loop, eliminating instructions with a variable shift size, reducing source memory access instructions, and eliminating excessive branching. These unrolled loops also allow much better code optimization by the C compiler. The code that selects which optimized variant is used is also simplified, eliminating integer divide instructions. The speed-up, measured by timing 'cat file.txt' in the console, varies between 40% and 70%, when testing on the Raspberry Pi and Allwinner ARM-based platforms, depending on font size and the pixel depth, with the greater benefit for 32bpp. Signed-off-by: Harm Hanemaaijer <fgenfb@yahoo.com> | 30 November 2013, 16:41:56 UTC |

| b200d06 | P33M | 21 April 2013, 23:08:36 UTC | dwc_otg: fix NAK holdoff and allow on split transactions only This corrects a bug where if a single active non-periodic endpoint had at least one transaction in its qh, on frnum == MAX_FRNUM the qh would get skipped and never get queued again. This would result in a silent device until error detection (automatic or otherwise) would either reset the device or flush and requeue the URBs. Additionally the NAK holdoff was enabled for all transactions - this would potentially stall a HS endpoint for 1ms if a previous error state enabled this interrupt and the next response was a NAK. Fix so that only split transactions get held off. | 30 November 2013, 16:41:50 UTC |

| fbb8034 | P33M | 21 March 2013, 19:36:17 UTC | dwc_otg: implement tasklet for returning URBs to usbcore hcd layer The dwc_otg driver interrupt handler for transfer completion will spend a very long time with interrupts disabled when a URB is completed - this is because usb_hcd_giveback_urb is called from within the handler which for a USB device driver with complicated processing (e.g. webcam) will take an exorbitant amount of time to complete. This results in missed completion interrupts for other USB packets which lead to them being dropped due to microframe overruns. This patch splits returning the URB to the usb hcd layer into a high-priority tasklet. This will have most benefit for isochronous IN transfers but will also have incidental benefit where multiple periodic devices are active at once. | 30 November 2013, 16:41:47 UTC |

Usually, this resulted in an OOPS during URB submission. By predetermining whether transactions need to be queued or not, this unsafe pointer access is avoided.

The maximum overall timeout was reduced from 100ms to 30ms, which isn't enough for many cards. Increase it to 150ms, just to be extra safe. According to commit 872a8ff in the MMC subsystem, some cards require crazy long timeouts (3s), but as we're busy-waiting, and shouldn't delay for such a long time, let's hope 150ms will be enough for most cards. | 30 November 2013, 16:41:00 UTC |

| 4004afd | Kees Cook | 12 November 2013, 23:11:17 UTC | exec/ptrace: fix get_dumpable() incorrect tests commit d049f74f2dbe71354d43d393ac3a188947811348 upstream. The get_dumpable() return value is not boolean. Most users of the function actually want to be testing for non-SUID_DUMP_USER(1) rather than SUID_DUMP_DISABLE(0). The SUID_DUMP_ROOT(2) is also considered a protected state. Almost all places did this correctly, excepting the two places fixed in this patch. Wrong logic: if (dumpable == SUID_DUMP_DISABLE) { /* be protective */ } or if (dumpable == 0) { /* be protective */ } or if (!dumpable) { /* be protective */ } Correct logic: if (dumpable != SUID_DUMP_USER) { /* be protective */ } or if (dumpable != 1) { /* be protective */ } Without this patch, if the system had set the sysctl fs/suid_dumpable=2, a user was able to ptrace attach to processes that had dropped privileges to that user. (This may have been partially mitigated if Yama was enabled.) The macros have been moved into the file that declares get/set_dumpable(), which means things like the ia64 code can see them too.

| ca23559 | Hans de Goede | 28 September 2013, 13:25:39 UTC | Bluetooth: revert: "Bluetooth: Add missing reset_resume dev_pm_ops" commit b1a8014471b01dd862de9f91bbbff1296afac42d upstream. Many btusb devices have 2 modes, a hid mode and a bluetooth hci mode. These devices default to hid mode for BIOS use. This means that after having been reset they will revert to HID mode, and are no longer usable as a HCI. Therefor it is a very bad idea to just blindly make reset_resume point to the regular resume handler. Note that the btusb driver has no clue how to switch these devices from hid to hci mode, this is done in userspace through udev rules, so the proper way to deal with this is to not have a reset-resume handler and instead let the usb-system re-enumerate the device, and re-run the udev rules. I must also note, that the commit message for the commit causing this problem has a very weak motivation for the change: "Add missing reset_resume dev_pm_ops. Missing reset_resume results in the following message after power management device test. This change sets reset_resume to btusb_resume(). [ 2506.936134] btusb 1-1.5:1.0: no reset_resume for driver btusb? [ 2506.936137] btusb 1-1.5:1.1: no reset_resume for driver btusb?" Making a change solely to silence a warning while also changing important behavior (normal resume handling versus re-enumeration) requires a commit message with a proper explanation why it is safe to do so, which clearly lacks here, and unsurprisingly it turns out to not be safe to make this change. Reverting the commit in question fixes bt no longer working on my Dell E6430 after a suspend/resume, and I believe it likely also fixes the following bugs: https://bugzilla.redhat.com/show_bug.cgi?id=988481 https://bugzilla.redhat.com/show_bug.cgi?id=1010649 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213239 This reverts commit 502f769662978a2fe99d0caed5e53e3006107381.
