Writing to dscr_default in sysfs doesn't actually change the DSCR - we rely on a context switch on each CPU to do the work. There is no guarantee we will get a context switch in a reasonable amount of time so fire off an IPI to force an immediate change.

The CPU hotplug code for the powernv platform currently only puts offline CPUs into nap mode if the powersave_nap variable is set. However, HV-style KVM on this platform requires secondary CPU threads to be offline and in nap mode. Since we know nap mode works just fine on all POWER7 machines, and the only machines that support the powernv platform are POWER7 machines, this changes the code to always put offline CPUs into nap mode, regardless of powersave_nap. Powersave_nap still controls whether or not CPUs go into nap mode when idle, as before.

At the moment the handler for hypervisor decrementer interrupts is the same as for decrementer interrupts, i.e. timer_interrupt(). This is bogus; if we ever do get a hypervisor decrementer interrupt it won't have anything to do with the next timer event. In fact the only time we get hypervisor decrementer interrupts is when one is left pending on exit from a KVM guest. When we get a hypervisor decrementer interrupt we don't need to do anything special to clear it, since they are edge-triggered on the transition of HDEC from 0 to -1. Thus this adds an empty handler function for them. We don't need to have them masked when interrupts are soft-disabled, so we use STD_EXCEPTION_HV instead of MASKABLE_EXCEPTION_HV.

Andreas Bombe reported that the added ktime_t overflow checking added to timespec_valid in commit 4e8b1452 ("time: Improve sanity checking of timekeeping inputs") was causing problems with X.org because it caused timeouts larger then KTIME_T to be invalid. Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid. This patch splits the ktime_t overflow checking into a new timespec_valid_strict function, and converts the timekeeping codes internal checking to use this more strict function.

Existing code assumes that del_timer returns true for alive conntrack entries. However, this is not true if reliable events are enabled. In that case, del_timer may return true for entries that were just inserted in the dying list. Note that packets / ctnetlink may hold references to conntrack entries that were just inserted to such list. This patch fixes the issue by adding an independent timer for event delivery. This increases the size of the ecache extension. Still we can revisit this later and use variable size extensions to allocate this area on demand.

When tearing down a net namespace, ipv4 mr_table structures are freed without first deactivating their timers. This can result in a crash in run_timer_softirq. This patch mimics the corresponding behaviour in ipv6. Locking and synchronization seem to be adequate. We are about to kfree mrt, so existing code should already make sure that no other references to mrt are pending or can be created by incoming traffic. The functions invoked here do not cause new references to mrt or other race conditions to be created. Invoking del_timer_sync guarantees that ipmr_expire_timer is inactive. Both ipmr_expire_process (whose completion we may have to wait in del_timer_sync) and mroute_clean_tables internally use mfc_unres_lock or other synchronizations when needed, and they both only modify mrt.

由 Bruce Allan 提交于
With a low enough MSS on the link partner and TSO enabled locally, the networking stack can periodically send a very large (e.g. 64KB) TCP message for which the driver will attempt to use more Tx descriptors than are available by default in the Tx ring. This is due to a workaround in the code that imposes a limit of only 4 MSS-sized segments per descriptor which appears to be a carry-over from the older e1000 driver and may be applicable only to some older PCI or PCIx parts which are not supported in e1000e. When the driver gets a message that is too large to fit across the configured number of Tx descriptors, it stops the upper stack from queueing any more and gets stuck in this state. After a timeout, the upper stack assumes the adapter is hung and calls the driver to reset it. Remove the unnecessary limitation of using up to only 4 MSS-sized segments per Tx descriptor, and put in a hard failure test to catch when attempting to check for message sizes larger than would fit in the whole Tx ring. Refactor the remaining logic that limits the size of data per Tx descriptor from a seemingly arbitrary 8KB to a limit based on the dynamic size of the Tx packet buffer as described in the hardware specification. Also, fix the logic in the check for space in the Tx ring for the next largest possible packet after the current one has been successfully queued for transmit, and use the appropriate defines for default ring sizes in e1000_probe instead of magic values. This issue goes back to the introduction of e1000e in 2.6.24 when it was split off from e1000.

Initialize return variable before exiting on an error path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: NJulia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: NPablo Neira Ayuso <pablo@netfilter.org>

[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).
