This patch enables support for the Sigmatel's STIR421x IrDA chip. Once patched with Sigmatel's firmware, this chip "almost" follows the USB-IrDA spec. Thus this patch is against irda-usb.[ch]. The code has been tested by Nick Fedchik on an STIR4210 chipset based dongle. Signed-off-by:

This patch integrates the smcinit code into the smsc-ircc driver. Some laptops have their smsc-ircc chip not properly configured by the BIOS and needs some preconfiguration. Currently, this can be done from userspace with smcinit, a utility that comes with the irda-utils package. It messes with ioports and PCI settings, from userspace. Now with this patch, if we happen to be on one of the known to be faulty laptops, we preconfigure the chip from the driver. Patch from Linus Walleij <triad@df.lth.se> Signed-off-by:

This patch changes GRE and SIT to generate port unreachable instead of protocol unreachable errors when we can't find a matching tunnel for a packet. This removes the ambiguity as to whether the error is caused by no tunnel being found or by the lack of support for the given tunnel type. Signed-off-by:

this fixes coverity bug id #1068. hci_send_sco() frees skb if (skb->len > hdev->sco_mtu). Since it returns a negative error value only in this case, we can directly return here. Signed-off-by:

This patch moves the sending of ICMP messages when there are no IPv4/IPv6 tunnels present to tunnel4/tunnel6 respectively. Please note that for now if xfrm4_tunnel/xfrm6_tunnel is loaded then no ICMP messages will ever be sent. This is similar to how we handle AH/ESP/IPCOMP. This move fixes the bug where we always send an ICMP message when there is no ip6_tunnel device present for a given packet even if it is later handled by IPsec. It also causes ICMP messages to be sent when no IPIP tunnel is present. I've decided to use the "port unreachable" ICMP message over the current value of "address unreachable" (and "protocol unreachable" by GRE) because it is not ambiguous unlike the other ones which can be triggered by other conditions. There seems to be no standard specifying what value must be used so this change should be OK. In fact we should change GRE to use this value as well. Incidentally, this patch also fixes a fairly serious bug in xfrm6_tunnel where we don't check whether the embedded IPv6 header is present before dereferencing it for the inside source address. This patch is inspired by a previous patch by Hugo Santos <hsantos@av.it.pt>. Signed-off-by:

The conntrack code doesn't do re-fragmentation of defragmented packets anymore but relies on fragmentation in the IP layer. Purely bridged packets don't pass through the IP layer, so the bridge netfilter code needs to take care of fragmentation itself. Signed-off-by:

Seems like leaf (end-nodes) has been freed by __tnode_free_rcu and not by __leaf_free_rcu. This fixes the problem. Only tnode_free is now used which checks for appropriate node type. free_leaf can be removed. Signed-off-by:

This effectively undoes the PCI resource allocation changes done in commit b408cbc7, but leaves the cleanups of that commit in place. We're going back to marking the resources reported by e820 busy _before_ doing PCI probing, so that any PCI resource that clashes with the BIOS- reported memory map will be reloacted to a non-clashing area. The reason? Larry Finger reports that his laptop has the cardbus controller set up by the BIOS so that it conflicts with the e820 memory map, and needs to be relocated. See http://bugzilla.kernel.org/show_bug.cgi?id=6337 for more details. We'll have to work out how to handle the fbcon problem that caused that commit in the first place in some other way.

In linux-2.6.16, we have noticed a problem where the gs base value returned from an arch_prtcl(ARCH_GET_GS, ...) call will be incorrect if: - the current/calling task has NOT set its own gs base yet to a non-zero value, - some other task that ran on the same processor previously set their own gs base to a non-zero value. In this situation, the ARCH_GET_GS code will read and return the MSR_KERNEL_GS_BASE msr register. However, since the __switch_to() code does NOT load/zero the MSR_KERNEL_GS_BASE register when the task that is switched IN has a zero next->gs value, the caller of arch_prctl(ARCH_GET_GS, ...) will get back the value of some previous tasks's gs base value instead of 0. Change the arch_prctl() ARCH_GET_GS code to only read and return the MSR_KERNEL_GS_BASE msr register if the 'gs' register of the calling task is non-zero. Side note: Since in addition to using arch_prctl(ARCH_SET_GS, ...), a task can also setup a gs base value by using modify_ldt() and write an index value into 'gs' from user space, the patch below reads 'gs' instead of using thread.gs, since in the modify_ldt() case, the thread.gs value will be 0, and incorrect value would be returned (the task->thread.gs value). When the user has not set its own gs base value and the 'gs' register is zero, then the MSR_KERNEL_GS_BASE register will not be read and a value of zero will be returned by reading and returning 'task->thread.gs'. The first patch shown below is an attempt at implementing this approach. Signed-off-by: -

If the HPET timer is enabled, the clock can drift by ~3 seconds a day. This is due to the HPET timer not being initialized with the correct setting (still using PIT count). If HZ changes, this drift can become even more pronounced. HPET patch initializes tick_nsec with correct tick_nsec settings for HPET timer. Vojtech comments: "It's not entirely correct (it assumes the HPET ticks totally exactly), but it's significantly better than assuming the PIT error there." Signed-off-by:

Previously only the first bus would be checked against Type 1. Why 16? Checking all would need too much memory and we can assume that systems with more than 16 busses have better than average quality BIOS. This is an additional defense against bad MCFG tables. Signed-off-by:

Intel EM64T CPUs handle uncanonical return addresses differently from AMD CPUs. The exception is reported in the SYSRET, not the next instruction. This leads to the kernel exception handler running on the user stack with the wrong GS because the kernel didn't expect exceptions on this instruction. This version of the patch has the teething problems that plagued an earlier version fixed. This is CVE-2006-0744 Thanks to Ernie Petrides and Asit B. Mallick for analysis and initial patches.

The generic linux/numa.h file defines NODES_SHIFT to 0 in case the architecture did not. Every architecture which has a NUMA config option defines NODES_SHIFT in its asm-$ARCH headers, but only if NUMA is enabled, except for x86_64. This should make it like all the rest. Signed-off-by:

AMD systems have a modern APIC that supports 8 bit IDs, but don't have a XAPIC version number. Add a new "modern_apic" subfunction that handles this correctly and use it (nearly) everywhere where XAPIC is tested for. I removed one wart: the code specified that external APICs would use an 8bit APIC ID. But I checked a real 82093 data sheet and it says clearly that they only use 4bit. So I removed this special case since it would a bit awkward to implement now. I removed the valid APIC tests in mptable parsing completely. On any modern system they only check against the full field width (8bit) anyways and are no-ops. This also fixes them doing the wrong thing on >8 core Opterons. This makes i386 boot again on 16 core Opterons. Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by:

When nolapic was passed or the local APIC was disabled for another reason ACPI would still parse the IO-APICs until these were explicitely disabled with noapic. Usually this resulted in a non booting configuration unless "nolapic noapic" was used. I also disabled the local APIC parsing in this case, although that's only cosmetic (suppresses a few printks) This hopefully makes nolapic work in all cases. Signed-off-by:

Horus systems don't have anything on bus 0 which makes the Type 1 sanity checks fail. Use the DMI BIOS year to check for newer systems and always assume Type 1 works on them.

This patch introduces a user for the e820_all_mapped function: There have been several machines that don't have a working MMCONFIG, often because of a buggy MCFG table in the ACPI bios. This patch adds a simple sanity check that detects a whole bunch of these cases, and when it detects it, linux now boots rather than crash-and-burns. The accuracy of this detection can in principle be improved if there was a "is this entire range in e820 with THIS attribute", but no such function exist and the complexity needed for this is not really worth it; this simple check already catches most cases anyway.

Introduce a e820_all_mapped() function which checks if the entire range <start,end> is mapped with type. This is done by moving the local start variable to the end of each known-good region; if at the end of the function the start address is still before end, there must be a part that's not of the correct type; otherwise it's a good region.
