| * | | | | | | | | Audit: clean up all op= output to include string quotingEric Paris2009-06-24

Somehow this works but it's just wrong. This patch moves all of those that I could find to be quoted. Example: Change From: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1 subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op=remove rule key="number2" list=4 res=0 Change To: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1 subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op="remove rule" key="number2" list=4 res=0 Signed-off-by: Eric Paris <eparis@redhat.com>

However, some BIOSes use system notify events in device-specific ways that require the driver to be involved. This patch adds a ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag. When a driver sets this flag and supplies a .notify method, Linux/ACPI calls the .notify method for ALL notify events on the device, not just the device-specific (0x80-0xff) events.

Unlike "Device" definitions, "Processor" definitions do not have a _HID in the namespace, so we generate a fake _HID. By convention, all these fake _HIDs begin with "LNX". This does change the user-visible _HID for "Processor" objects -- previously, we used "ACPI_CPU" and this changes that to "LNXCPU", which starts with "LNX" as do all the other made-up _HIDs.

And there exists the strict dependency between the two drivers. The acpi video bus will be unloaded in course of unloading the i915 driver. If we unload the acpi video driver, then the kernel oops will be triggered. Add the reference count to avoid unloading the ACPI video bus twice. The reference count should be checked before unregistering the acpi video bus. If the reference count is already zero, it won't unregister it again. And after the acpi video bus is already unregistered, the reference count will be set to zero. http://bugzilla.kernel.org/show_bug.cgi?id=13396 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

This patch also changes the time-space tradeoff ever so slightly. Looking up the ACPI-PCI binding is never in the performance path, and by eliminating this caching, we save 24 bytes for each _ADR device in the ACPI namespace. This patch lays further groundwork to eventually eliminate the acpi_driver_ops.bind callback.

To be on the safe side, I added an skb_orphan call for all protocols by default since some of them (IP in particular) cannot handle receiving packets destructors properly. Now it seems that at least one protocol (CAN) expects to be able to pass skb->sk through the rx path without getting clobbered. So this patch attempts to fix this properly by moving the skb_orphan call to where it's actually needed. In particular, I've added it to skb_set_owner_[rw] which is what most users of skb->destructor call. This is actually an improvement for tun too since it means that we only give back the amount charged to the socket when the skb is passed to another socket that will also be charged accordingly.

Without source-id checking for interrupt remapping , a rouge guest/VM with assigned devices can launch interrupt attacks to bring down anothe guest/VM or the VMM itself. This patch adds source-id checking for interrupt remapping, and then really isolates interrupts for guests/VMs with assigned devices. Because PCI subsystem is not initialized yet when set up IOAPIC entries, use read_pci_config_byte to access PCI config space directly.

For example OCFS2 has system directories (for orphan inode tracking and for gathering all system files like journal or quota files into a single place) which have different locking locking rules than standard directories. For a filesystem setting lockdep map is naturaly done when the inode is read but we have to modify unlock_new_inode() not to overwrite the lockdep map the filesystem has set.

We have not identified a stronger case than KSM's daemon (not yet in mainline), but the issue must have come up before, since RHEL has included a fix for this for years (though a different fix, they just back out of grab_swap_token if current->mm is unset: which is what we first proposed, but using the right mm here seems more correct).

Not all no-mmu systems lack memory protection, so the read/write could feasibly be checked. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

We've had cases on Blackfin systems where test programs caused kernel crashes here because userspace passed up a NULL/-1 pointer and the kernel gladly attempted to run strlen() on it.

For example, image width must be even or a multiple of four. Some hardware has requirements that the total image size (width * height) be a multiple of some power of two. v4l_bound_align_image() will enforce min and max width and height, power of two alignment on width and height, and power of two alignment on total image size. It uses an efficient algorithm that will try to find the "closest" image size that meets the requirements.

Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls that allows you to pass these new arguments. The existing v4l2_i2c_new_subdev functions were modified to also call s_config. In the future the existing v4l2_i2c_new_subdev functions will be replaced by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.
