Not now, but it looks you are correct. q->qdisc is NULL until another additional qdisc is attached (beside tfifo). See 50612537. The following patch should work. From: Hagen Paul Pfeifer <hagen@jauu.net> netem: catch NULL pointer by updating the real qdisc statistic Reported-by:

Currently, the refill path for RX buffers will always allocate the buffers as GFP_ATOMIC, even if we are in process context. This will fail to apply memory pressure as the worker thread will not contribute to the freeing of memory. Fix this by changing add_recvbuf_small to use the gfp variant allocator, __netdev_alloc_skb_ip_align(). Signed-off-by:

This adds a new ndo_get_fcoe_hbainfo() call in net_device_ops for FCoE protocol stack. If supported by the underlying device, the FCoE protocol stack will call this to get device specific information from the underlying device. This information will then be utilized by the FCoE protocol stack to register Fiber Channel HBA attributes with the Fiber Channel Management Service via Fabric Device Management Interface (FDMI) as per the T11 FC-GS specification.

According to 82576_Datasheet.pdf, PHY setting is lost after PHY power down. So resetting PHY is needed when recovering from PHY power down to set a default setting to PHY register. Owing to this lack, NIC doesn't link up in some rare situation. Signed-off-by:

Use the runtime power management framework to add basic runtime PM support to the igb driver. Namely, make the driver suspend the device when the link is off and set it up for generating a wakeup event after the link has been detected again. This feature is disabled by default. Based on e1000e's runtime PM code. Changes since v1: Don't suspend the device when shutting down the interface. Avoid race between runtime suspending and ethtool operations. Signed-off-by:

As reported by Steven Rostedt, e1000 has a lockdep splat added during the recent merge window. The issue is that cancel_delayed_work is called while holding our private mutex. There is no reason that I can see to hold the mutex during pci shutdown, it was more just paranoia that I put the mutex_lock around the call to e1000_down. In a quick survey lots of drivers handle locking differently when being called by the pci layer. The assumption here is that we don't need the mutexes' protection in this function because the driver could not be unloaded while in the shutdown handler which is only called at reboot or poweroff.

This is the temporary simple fix for 3.2, we need more changes in this area. 1. do_signal_stop() assumes that the running untraced thread in the stopped thread group is not possible. This was our goal but it is not yet achieved: a stopped-but-resumed tracee can clone the running thread which can initiate another group-stop. Remove WARN_ON_ONCE(!current->ptrace). 2. A new thread always starts with ->jobctl = 0. If it is auto-attached and this group is stopped, __ptrace_unlink() sets JOBCTL_STOP_PENDING but JOBCTL_STOP_SIGMASK part is zero, this triggers WANR_ON(!signr) in do_jobctl_trap() if another debugger attaches. Change __ptrace_unlink() to set the artificial SIGSTOP for report. Alternatively we could change ptrace_init_task() to copy signr from current, but this means we can copy it for no reason and hide the possible similar problems. Acked-by:

Test-case: int main(void) { int pid, status; pid = fork(); if (!pid) { for (;;) { if (!fork()) return 0; if (waitpid(-1, &status, 0) < 0) { printf("ERR!! wait: %m\n"); return 0; } } } assert(ptrace(PTRACE_ATTACH, pid, 0,0) == 0); assert(waitpid(-1, NULL, 0) == pid); assert(ptrace(PTRACE_SETOPTIONS, pid, 0, PTRACE_O_TRACEFORK) == 0); do { ptrace(PTRACE_CONT, pid, 0, 0); pid = waitpid(-1, NULL, 0); } while (pid > 0); return 1; } It fails because ->real_parent sees its child in EXIT_DEAD state while the tracer is going to change the state back to EXIT_ZOMBIE in wait_task_zombie(). The offending commit is 823b018e which moved the EXIT_DEAD check, but in fact we should not blame it. The original code was not correct as well because it didn't take ptrace_reparented() into account and because we can't really trust ->ptrace. This patch adds the additional check to close this particular race but it doesn't solve the whole problem. We simply can't rely on ->ptrace in this case, it can be cleared if the tracer is multithreaded by the exiting ->parent. I think we should kill EXIT_DEAD altogether, we should always remove the soon-to-be-reaped child from ->children or at least we should never do the DEAD->ZOMBIE transition. But this is too complex for 3.2. Reported-and-tested-by:Denys Vlasenko <vda.linux@googlemail.com> Tested-by:

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop route for the interface we're adding an addres to was wrong (see commit 7ffbcecb). for one, it never triggers, and two, it was completely wrong to begin with. This test was meant to cover this section of RFC 4429: 3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration * (modifies section 5.5) A host MAY choose to configure a new address as an Optimistic Address. A host that does not know the SLLAO of its router SHOULD NOT configure a new address as Optimistic. A router SHOULD NOT configure an Optimistic Address. This patch should bring us into proper compliance with the above clause. Since we only add a SLAAC address after we've received a RA which may or may not contain a source link layer address option, we can pass a pointer to that option to addrconf_prefix_rcv (which may be null if the option is not present), and only set the optimistic flag if the option was found in the RA. Change notes: (v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than a pointer to make its use more clear as per request from davem. Signed-off-by:
