2007-11-29Fix <linux/kd.h> usage in userspaceDavid Woodhouse
For reasons unclear to me, glibc's <sys/kd.h> deliberately defeats the attempt we make in <linux/kd.h> to include <linux/types.h> For now, change the one instance of __u32 to 'unsigned int' instead because it's breaking userspace. We should probably also remove our inclusion of <linux/types.h>, since we don't use it -- but that's not a change to make in -rc.

2007-11-29PNP: increase the maximum number of resourcesZhao Yakui
On some systems the number of resources(IO,MEM) returnedy by PNP device is greater than the PNP constant, for example motherboard devices. It brings that some resources can't be reserved and resource confilicts. This will cause PCI resources are assigned wrongly in some systems, and cause hang. This is a regression since we deleted ACPI motherboard driver and use PNP system driver.

2007-11-28USB: keep track of whether interface sysfs files existAlan Stern
This patch (as1009) solves the problem of multiple registrations for USB sysfs files in a more satisfying way than the existing code. It simply adds a flag to keep track of whether or not the files have been created; that way the files can be created or removed as needed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu>

2007-11-26[SKBUFF]: Free old skb properly in skb_morphHerbert Xu
The skb_morph function only freed the data part of the dst skb, but leaked the auxiliary data such as the netfilter fields. This patch fixes this by moving the relevant parts from __kfree_skb to skb_release_all and calling it in skb_morph. It also makes kfree_skbmem static since it's no longer called anywhere else and it now no longer does skb_release_data. Thanks to Yasuyuki KOZAKAI for finding this problem and posting a patch for it.

2007-11-14pidns: Place under CONFIG_EXPERIMENTALEric W. Biederman
This is my trivial patch to swat innumerable little bugs with a single blow. After some intensive review (my apologies for not having gotten to this sooner) what we have looks like a good base to build on with the current pid namespace code but it is not complete, and it is still much to simple to find issues where the kernel does the wrong thing outside of the initial pid namespace. Until the dust settles and we are certain we have the ABI and the implementation is as correct as humanly possible let's keep process ID namespaces behind CONFIG_EXPERIMENTAL. Allowing us the option of fixing any ABI or other bugs we find as long as they are minor. Allowing users of the kernel to avoid those bugs simply by ensuring their kernel does not have support for multiple pid namespaces.

2007-11-14rtc: fall back to requesting only the ports we actually useBjorn Helgaas
Firmware like PNPBIOS or ACPI can report the address space consumed by the RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT) assumed by the RTC driver. The PNP core doesn't request resources yet, but I'd like to make it do so. If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC driver from loading. Since we only use the RTC index and data registers at RTC_PORT(0) and RTC_PORT(1), we can fall back to requesting just enough space for those. If the PNP core requests resources, this results in typical I/O port usage like this: 0070-0073 : 00:06 <-- PNP device 00:06 responds to 70-73 0070-0071 : rtc <-- RTC driver uses only 70-71 instead of the current: 0070-0077 : rtc <-- RTC_IO_EXTENT == 8 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-14revert "Task Control Groups: example CPU accounting subsystem"Andrew Morton
Revert 62d0df64065e7c135d0002f069444fbdfc64768f. This was originally intended as a simple initial example of how to create a control groups subsystem; it wasn't intended for mainline, but I didn't make this clear enough to Andrew. The CFS cgroup subsystem now has better functionality for the per-cgroup usage accounting (based directly on CFS stats) than the "usage" status file in this patch, and the "load" status file is rather simplistic - although having a per-cgroup load average report would be a useful feature, I don't believe this patch actually provides it.

2007-11-14hugetlb: follow_hugetlb_page() for write accessAdam Litke
When calling get_user_pages(), a write flag is passed in by the caller to indicate if write access is required on the faulted-in pages. Currently, follow_hugetlb_page() ignores this flag and always faults pages for read-only access. This can cause data corruption because a device driver that calls get_user_pages() with write set will not expect COW faults to occur on the returned pages. This patch passes the write flag down to follow_hugetlb_page() and makes sure hugetlb_fault() is called with the right write_access parameter.

2007-11-12[NET]: Add the helper kernel_sock_shutdown()Trond Myklebust
...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers. Looking at the sock->op->shutdown() handlers, it looks as if all of them take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the RCV_SHUTDOWN/SEND_SHUTDOWN arguments. Add a helper, and then define the SHUT_* enum to ensure that kernel users of shutdown() don't get confused.

2007-11-12virtio: Force use of power-of-two for descriptor ring sizesRusty Russell
The virtio descriptor rings of size N-1 were nicely set up to be aligned to an N-byte boundary. But as Anthony Liguori points out, the free-running indices used by virtio require that the sizes be a power of 2, otherwise we get problems on wrap (demonstrated with lguest). So we replace the clever "2^n-1" scheme with a simple "align to page boundary" scheme: this means that all virtio rings take at least two pages, but it's safer than guessing cache alignment.

2007-11-12virtio: fix vring_init for 64 bitsAnthony Liguori
This patch fixes a typo in vring_init(). This happens to work today in lguest because the sizeof(struct vring_desc) is 16 and struct vring contains 3 pointers and an unsigned int so on 32-bit sizeof(struct vring_desc) == sizeof(struct vring). However, this is no longer true on 64-bit where the bug is exposed. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-11-10[NET]: Fix skb_truesize_check() assertionChuck Lever
The intent of the assertion in skb_truesize_check() is to check for skb->truesize being decremented too much by other code, resulting in a wraparound below zero. The type of the right side of the comparison causes the compiler to promote the left side to an unsigned type, despite the presence of an explicit type cast. This defeats the check for negativity. Ensure both sides of the comparison are a signed type to prevent the implicit type conversion. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-11-09sched: avoid large irq-latencies in smp-balancingPeter Zijlstra
SMP balancing is done with IRQs disabled and can iterate the full rq. When rqs are large this can cause large irq-latencies. Limit the nr of iterations on each run. This fixes a scheduling latency regression reported by the -rt folks.
