2008-03-26[IPSEC]: Fix BEET outputHerbert Xu
The IPv6 BEET output function is incorrectly including the inner header in the payload to be protected. This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function. Thanks to Joakim Koskela for finding this problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-03-26x86: fix performance drop for glxSuresh Siddha
fix the 3D performance drop reported at: http://bugzilla.kernel.org/show_bug.cgi?id=10328 fb drivers are using ioremap()/ioremap_nocache(), followed by mtrr_add with WC attribute. Recent changes in page attribute code made both ioremap()/ioremap_nocache() mappings as UC (instead of previous UC-). This breaks the graphics performance, as the effective memory type is UC instead of expected WC. The correct way to fix this is to add ioremap_wc() (which uses UC- in the absence of PAT kernel support and WC with PAT) and change all the fb drivers to use this new ioremap_wc() API. We can take this correct and longer route for post 2.6.25. For now, revert back to the UC- behavior for ioremap/ioremap_nocache.

we could call find_max_pfn() directly instead of setup_memory() to get max_pfn needed for mtrr trimming. otherwise setup_memory() is called two times... that is duplicated... [ mingo@elte.hu: both Thomas and me simulated a double call to setup_bootmem_allocator() and can confirm that it is a real bug which can hang in certain configs.

2008-03-26SVCRDMA: Check num_sge when setting LAST_CTXT bitTom Tucker
The RDMACTXT_F_LAST_CTXT bit was getting set incorrectly when the last chunk in the read-list spanned multiple pages. This resulted in a kernel panic when the wrong context was used to build the RPC iovec page list. RDMA_READ is used to fetch RPC data from the client for NFS_WRITE requests. A scatter-gather is used to map the advertised client side buffer to the server-side iovec and associated page list. WR contexts are used to convey which scatter-gather entries are handled by each WR. When the write data is large, a single RPC may require multiple RDMA_READ requests so the contexts for a single RPC are chained together in a linked list. The last context in this list is marked with a bit RDMACTXT_F_LAST_CTXT so that when this WR completes, the CQ handler code can enqueue the RPC for processing. The code in rdma_read_xdr was setting this bit on the last two contexts on this list when the last read-list chunk spanned multiple pages. This caused the svc_rdma_recvfrom logic to incorrectly build the RPC and caused the kernel to crash because the second-to-last context doesn't contain the iovec page list. Modified the condition that sets this bit so that it correctly detects the last context for the RPC.

2008-03-26Revert "PCI: remove transparent bridge sizing"Linus Torvalds
This reverts commit 8fa5913d54f3b1e09948e6a0db34da887e05ff1f, which caused various interesting problems for people, including wrong resource allocations. See for example bugzilla entry "2.6.25-rc2: ohci1394 problem (MMIO broken)" at http://bugzilla.kernel.org/show_bug.cgi?id=10080 And Gary Hade says: "The same change had also exposed an issue reported by Paul Martin that has been causing an Oops while hotplugging ThinkPads to a ThinkPad Dock II. See http://lkml.org/lkml/2008/2/19/405 http://bugzilla.kernel.org/show_bug.cgi?id=9961 I have a fix for the ThinkPad docking Oops but if the issue being discussed here is caused by the transparent bridge sizing removal change I totally agree that it should be reverted." The transparent bridge sizing removal change was motivated by insufficient PCI memory resource for a transparent bridge window that was being created as a result of expansion ROM(s) being included in the transparent bridge sizing calculations. A later "PCI: Remove default PCI expansion ROM memory allocation" change ( re: http://lkml.org/lkml/2007/12/11/361 ) removes the expansion ROM(s) from the transparent bridge sizing calculations which actually resolves the original issue in a different manner. So, even if the "PCI: remove transparent bridge sizing" is not problematic it is no longer needed anyway."

2008-03-26NOHZ: reevaluate idle sleep length after add_timer_on()Thomas Gleixner
add_timer_on() can add a timer on a CPU which is currently in a long idle sleep, but the timer wheel is not reevaluated by the nohz code on that CPU. So a timer can be delayed for quite a long time. This triggered a false positive in the clocksource watchdog code. To avoid this we need to wake up the idle CPU and enforce the reevaluation of the timer wheel for the next timer event. Add a function, which checks a given CPU for idle state, marks the idle task with NEED_RESCHED and sends a reschedule IPI to notify the other CPU of the change in the timer wheel. Call this function from add_timer_on().

2008-03-26[UML]: uml-net: don't set IFF_ALLMULTI in set_multicast_listPatrick McHardy
IFF_ALLMULTI is an indication from the network stack to the driver to disable multicast filters, drivers should never set it directly. Since the UML networking device doesn't have any filtering capabilites, it doesn't the set_multicast_list function at all, it is kept so userspace can still issue SIOCADDMULTI/SIOCDELMULTI ioctls however.

2008-03-26[VLAN]: Don't copy ALLMULTI/PROMISC flags from underlying devicePatrick McHardy
Changing these flags requires to use dev_set_allmulti/dev_set_promiscuity or dev_change_flags. Setting it directly causes two unwanted effects: - the next dev_change_flags call will notice a difference between dev->gflags and the actual flags, enable promisc/allmulti mode and incorrectly update dev->gflags - this keeps the underlying device in promisc/allmulti mode until the VLAN device is deleted Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-03-25[SPARC64]: Fix sparse warnings in arch/sparc64/kernel/{cpu,setup}.cDavid S. Miller
We create a local header file entry.h, under arch/sparc64/kernel/, that we can use to declare routines either defined in assembler or only invoked from assembler. As well as other data objects which are private to the inner sparc64 kernel arch code. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-03-25b44: Truncate PHY addressMichael Buesch
Some ROMs on embedded devices store incorrect values for the PHY address of the ethernet device. It looks like the number is sign-extended. Truncate the value by applying the PHY-address mask to it. The patch was tested on a bcm47xx embedded system (where the bug triggers) and a bcm4400 PCI card. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-25skge napi->poll() locking bugMarin Mitov
According to: Documentation/networking/netdevices.txt: <cite> napi->poll: .......... Context: softirq will be called with interrupts disabled by netconsole. </cite> napi->poll() could be called either with interrupts enabled (in softirq context) or disabled (by netconsole), so the irq flag should be preserved.
