2011-08-15dp83640: increase receive time stamp buffer sizeRichard Cochran
commit 8028837d71ba9904b17281b40f94b93e947fbe38 upstream. The dp83640 buffers receive time stamps from special PHY status frames, matching them to received PTP packets in a work queue. Because the timeout for orphaned time stamps is so long and the buffer is so small, the driver can drop time stamps under moderate PTP traffic. This commit fixes the issue by decreasing the timeout to (at least) one timer tick and increasing the buffer size. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S.

2011-08-15gianfar: fix fiper alignment after resetting the timeRichard Cochran
commit cbc056602c7c63620c86904c431ff6b61e029dcc upstream. After resetting the time, the PPS signals on the FIPER output channels are incorrectly offset from the clock time, as can be readily verified by a looping back the FIPER to the external time stamp input. Despite its name, setting the "Fiper Realignment Disable" bit seems to fix the problem, at least on the P2020. Also, following the example code from the Freescale BSP, it is not really necessary to disable and re-enable the timer in order to reprogram the FIPER. (The documentation is rather unclear on this point. It seems that writing to the alarm register also disables the FIPER.)

[ Upstream commit f4bb2e9c4fa9e5fdddf90589703613fd1a9c519f ] When a bond contains a device where one name is the subset of another (eth1 and eth10, for example), one cannot properly set the primary device or the currently active device. This was reported and based on work by Takuma Umeya. I also verified the problem and tested that this fix resolves it. V2: A few did not like the the current code or my changes, so I refactored bonding_store_primary and bonding_store_active_slave to be a bit cleaner, dropped the use of strnicmp since we did not really need the comparison to be case insensitive, and formatted the input string from sysfs so a comparison to IFNAMSIZ could be used. I also discovered an error in bonding_store_active_slave that would modify bond->primary_slave rather than bond->curr_active_slave before forcing the bonding driver to choose a new active slave.

2011-08-15net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2011-08-15drm/i915: Hold mode_config->mutex during hotplug processingKeith Packard
commit a65e34c79c88895766ab1f8a5afa451eed26622b upstream. Hotplug detection is a mode setting operation and must hold the struct_mutex or risk colliding with other mode setting operations. In particular, the display port hotplug function attempts to re-train the link if the monitor is supposed to be running when plugged back in. If that happens while mode setting is underway, the link will get scrambled, leaving it in an inconsistent state. This is a special case -- usually the driver mode setting entry points are covered by the upper level DRM code, but in this case the function is invoked as a work function not under the control of DRM.

commit f3234706a77bd6e1592ae71fb3268e04cb030dba upstream. Physically-addressed hardware status pages are initialized early in the driver load process by i915_init_phys_hws.

2011-08-15drm/i915/pch: Fix integer math bugs in panel fittingAdam Jackson
commit 302983e9059e9ef5de3ca7671918eeb237c5971e upstream. Consider a 1600x900 panel, upscaling a 1360x768 mode, full-aspect. The old math would give you: scaled_width = 1600 * 768; /* 1228800 */ scaled_height = 1360 * 900; /* 1224000 */ if (scaled_width > scaled_height) { /* pillarbox, and true */ width = 1224000 / 768; /* int(1593.75) = 1593 */ x = (1600 - 1593 + 1) / 2; /* 4 */ y = 0; height = 768; } /* ... */ This is broken. The total width of scanout would then be 1593 + 4 + 4, or 1601, which is wider than the panel itself. The hardware very dutifully implements this, and you end up with a black 45° diagonal from the top-left corner to the bottom edge of the screen. It's a cool effect and all, but not what you wanted. Similar things happen for the letterbox case. The problem is that you have an integer number of pixels, which means it's usually impossible to upscale equally on both axes. 1360/768 is 1.7708, 1600/900 is 1.7777. Since we're constrained on the one axis, the other one wants to come out as an even number of pixels (the panel is almost certainly even on both axes, and the x/y offsets will be applied on both sides). In the math above, if 'width' comes out even, rounding down is correct; if it's odd, you'd rather round up. So just increment width/height in those cases. Tested on a Lenovo T500 (Ironlake).

2011-08-15drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC ↵Thomas Reim
Lines (here: Asus M2A-VM HDMI) commit e384fab8c6f3ca88600bcb2ebdf0eb2f90864fab upstream. Some integrated ATI Radeon chipset implementations with add-on HDMI card (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even when the add-on card is not plugged in or HDMI is disabled in BIOS setup. In this case, drm_get_edid() and drm_edid_block_valid() periodically dump data and kernel errors into system log files and onto terminals. For these connectors DDC probing is extended by a check for a correct EDID header. Only in case a valid EDID header is also found, the (HDMI or DVI) connector will be used by the Radeon driver. This prevents the kernel driver from useless flooding of logs and terminal sessions with EDID dumps and error messages. This patch adds a flag 'requires_extended_probe' to the radeon_connector structure. In function radeon_connector_needs_extended_probe() this flag can be set on a chipset family/vendor/connector type specific basis. In addition, function radeon_ddc_probe() has been adapted to perform extended DDC probing if required by the connector's flag.

commit b6b67df3f24c45af0012ee3c8af2f62ca083ae18 upstream. This driver uses information from the self member of the pci_bus struct to get information regarding the bridge to which the PCIe device is attached. Unfortunately, this member is not established on all architectures, which leads to a kernel oops. Skipping the entire block that uses the self member to determine the bridge vendor will only affect RTL8192DE devices as that driver sets the ASPM support flag differently when the bridge vendor is Intel. If the self member is available, there is no functional change. This patch fixes Bugzilla No. 40212.

2011-08-04dm snapshot: flush disk cache when mergingMikulas Patocka
commit 762a80d9fc9f690a3a35983f3b4619a220650808 upstream. This patch makes dm-snapshot flush disk cache when writing metadata for merging snapshot. Without cache flushing the disk may reorder metadata write and other data writes and there is a possibility of data corruption in case of power fault.

2011-08-04dm io: flush cpu cache with vmapped ioMikulas Patocka
commit bb91bc7bacb906c9f3a9b22744c53fa7564b51ba upstream. For normal kernel pages, CPU cache is synchronized by the dma layer. However, this is not done for pages allocated with vmalloc. If we do I/O to/from vmallocated pages, we must synchronize CPU cache explicitly. Prior to doing I/O on vmallocated page we must call flush_kernel_vmap_range to flush dirty cache on the virtual address. After finished read we must call invalidate_kernel_vmap_range to invalidate cache on the virtual address, so that accesses to the virtual address return newly read data and not stale data from CPU cache. This patch fixes metadata corruption on dm-snapshots on PA-RISC and possibly other architectures with caches indexed by virtual address.

2011-08-04hvc_console: Improve tty/console put_chars handlingHendrik Brueckner
commit 8c2381af0d3ef62a681dac5a141b6dabb27bf2e1 upstream. Currently, the hvc_console_print() function drops console output if the hvc backend's put_chars() returns 0. This patch changes this behavior to allow a retry through returning -EAGAIN. This change also affects the hvc_push() function. Both functions are changed to handle -EAGAIN and to retry the put_chars() operation. If a hvc backend returns -EAGAIN, the retry handling differs: - hvc_console_print() spins to write the complete console output. - hvc_push() behaves the same way as for returning 0. Now hvc backends can indirectly control the way how console output is handled through the hvc console layer.

commit f2eb3cdf14457fccb14ae8c4d7d7cee088cd3957 upstream. Kconfig allows enabling console support for the SC26xx driver even when it's configured as a module resulting in a: ERROR: "uart_console_device" [drivers/tty/serial/sc26xx.ko] undefined! modpost error since the driver was merged in eea63e0e8a60d00485b47fb6e75d9aa2566b989b [SC26XX: New serial driver for SC2681 uarts] in 2.6.25.

2011-08-04tty/serial: Fix XSCALE serial ports, e.g. ce4100Stephen Warren
commit 5568181f188ae9485a0cdbea5ea48f63d186a298 upstream. Commit 4539c24fe4f92c09ee668ef959d3e8180df619b9 "tty/serial: Add explicit PORT_TEGRA type" introduced separate flags describing the need for IER bits UUE and RTOIE. Both bits are required for the XSCALE port type. While that patch updated uart_config[] as required, the auto-probing code wasn't updated to set the RTOIE flag when an XSCALE port type was detected. This caused such ports to stop working. This patch rectifies that.

2011-08-04EHCI: fix direction handling for interrupt data togglesAlan Stern
commit e04f5f7e423018bcec84c11af2058cdce87816f3 upstream. This patch (as1480) fixes a rather obscure bug in ehci-hcd. The qh_update() routine needs to know the number and direction of the endpoint corresponding to its QH argument. The number can be taken directly from the QH data structure, but the direction isn't stored there. The direction is taken instead from the first qTD linked to the QH. However, it turns out that for interrupt transfers, qh_update() gets called before the qTDs are linked to the QH. As a result, qh_update() computes a bogus direction value, which messes up the endpoint toggle handling. Under the right combination of circumstances this causes usb_reset_endpoint() not to work correctly, which causes packets to be dropped and communications to fail. Now, it's silly for the QH structure not to have direct access to all the descriptor information for the corresponding endpoint. Ultimately it may get a pointer to the usb_host_endpoint structure; for now, adding a copy of the direction flag solves the immediate problem. This allows the Spyder2 color-calibration system (a low-speed USB device that sends all its interrupt data packets with the toggle set to 0 and hance requires constant use of usb_reset_endpoint) to work when connected through a high-speed hub. Thanks to Graeme Gill for supplying the hardware that allowed me to track down this bug.

2011-08-04EHCI: only power off port if over-current is activeSergei Shtylyov
commit 81463c1d707186adbbe534016cd1249edeab0dac upstream. MAX4967 USB power supply chip we use on our boards signals over-current when power is not enabled; once it's enabled, over-current signal returns to normal. That unfortunately caused the endless stream of "over-current change on port" messages. The EHCI root hub code reacts on every over-current signal change with powering off the port -- such change event is generated the moment the port power is enabled, so once enabled the power is immediately cut off. I think we should only cut off power when we're seeing the active over-current signal, so I'm adding such check to that code. I also think that the fact that we've cut off the port power should be reflected in the result of GetPortStatus request immediately, hence I'm adding a PORTSCn register readback after write...

2011-08-04geode: reflect mfgpt dependency on mfdPhilip A. Prindeville
commit 703f03c896fdbd726b809066ae279df513992f0e upstream. As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs which then make the GPIO, MFGPT, ACPI, etc. all visible to the system. So the dependencies of the MFGPT stuff have changed, and most people expect Kconfig to bring in the necessary dependencies. Without them, the module fails to load and most people don't understand why because the details of the rewrite aren't captured anywhere most people who know to look. This dependency needs to be reflected in Kconfig. Signed-off-by: Philip A. Prindeville <philipp@redfish-solutions.com> Acked-by: Alexandros C.

2011-08-04PCI: ARI is a PCIe v2 featureChris Wright
commit 864d296cf948aef0fa32b81407541572583f7572 upstream. The function pci_enable_ari() may mistakenly set the downstream port of a v1 PCIe switch in ARI Forwarding mode. This is a PCIe v2 feature, and with an SR-IOV device on that switch port believing the switch above is ARI capable it may attempt to use functions 8-255, translating into invalid (non-zero) device numbers for that bus. This has been seen to cause Completion Timeouts and general misbehaviour including hangs and panics.
