| | | | | | | | | Some ALi devices report simplex if they have been disabled and re-enabled, and restoring the byte does not work.

* pata_legacy: wait for async probingJames Bottomley2009-06-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic problem here that pata_legacy attaches the host, sees if it found any devices and detaches it if none were found. With async probing, it's not waiting until discovery is finished before deciding it has no devices and trying the detach leading to this warning: ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ------------[ cut here ]------------ WARNING: at drivers/ata/libata-core.c:6222 ata_host_detach+0x75/0x90() Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.30-rc7 #1 Call Trace: [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01139b5>] ? warn_slowpath_common+0x45/0x80 [<c01139fa>] ? warn_slowpath_null+0xa/0x10 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c02f40e0>] ? legacy_init+0x44e/0x87f [<c02f3c92>] ? legacy_init+0x0/0x87f [<c0101021>] ? _stext+0x21/0x140 [<c01890ff>] ? proc_register+0x2f/0x190 [<c018938c>] ? create_proc_entry+0x5c/0xc0 [<c0135ebe>] ? register_irq_proc+0x6e/0x90 [<c02e6484>] ? kernel_init+0x6e/0xbf [<c02e6416>] ? kernel_init+0x0/0xbf [<c01031d7>] ? kernel_thread_helper+0x7/0x10 ---[ end trace ef1ee36e873ae3a0 ]--- Because it detaches before the probe is complete. One way to fix it would be to put an async_synchronize_full() before looking for devices, which this patch does. A better way might be to separate libata into its own domain and only wait for that.

Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

* | drivers/char/mem.c: avoid OOM lockup during large reads from /dev/zeroSalman Qazi2009-06-041-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running 20 parallel instances of dd as follows: #!/bin/bash for i in `seq 1 20`; do dd if=/dev/zero of=/export/hda3/dd_$i bs=1073741824 count=1 & done wait on a 16G machine, we noticed that rather than just killing the processes, the entire kernel went down. Stracing dd reveals that it first does an mmap2, which makes 1GB worth of zero page mappings. Then it performs a read on those pages from /dev/zero, and finally it performs a write. The machine died during the reads. Looking at the code, it was noticed that /dev/zero's read operation had been changed by 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving zero page mappings to actually zeroing the page. The zeroing of the pages causes physical pages to be allocated to the process. But, when the process exhausts all the memory that it can, the kernel cannot kill it, as it is still in the kernel mode allocating more memory. Consequently, the kernel eventually crashes. To fix this, I propose that when a fatal signal is pending during /dev/zero read operation, we simply return and let the user process die.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch to fix bad length checking in e1000. E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Tested-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

Babbling RX error (IEVENT_BABR) should be included in IEVENT_ERROR_MASK. Otherwise if BABR is raised, it never gets handled nor cleared, and an interrupt storm results. This has been observed to happen on sending a burst of ethernet frames to a gianfar based board. Signed-off-by: Xiaotian Feng <xiaotian.feng@windriver.com> Signed-off-by: David S.

Replace that build-time scheme with a load-time module parameter: "7300_idle.forceload=1" to make it easier to test the driver on hardware that while not officially validated, works fine and is much more commonly available. By default (no modparam) the driver will continue to load only on the i7300. Note that ioat_dma runs a copy of i7300_idle's probe routine to know to reserve an IOAT channel for i7300_idle. This change makes ioat_dma do that always on the i5000, just like it does on the i7300. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Andrew Henroid <andrew.d.henroid@intel.com>

Because of this, I got the following kernel oops when I was doing some pci hotplug operations. This patch fixes this bug by replacing wrong hand-made pci_find_slot() with pci_get_slot() in acpi_pci_bind().

These are outrageous values for frequency, power and latency, raising the question where to draw the line between legal and illegal. We tend to survive garbage in the power and latency fields, but we can BUG_ON when garbage is in the frequency field. Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz. So disregard a _PSS with a frequency so large that it can't be represented by cpufreq. https://bugzilla.redhat.com/show_bug.cgi?id=500311 Signed-off-by: Len Brown <len.brown@intel.com>
