Changes to support other Optima types, introduced an accidental regression that caused 88E8059 to come up in 10Mbit/sec. The Yukon Optima supports a reverse auto-negotiation feature that was incorrectly setup, and not needed. The feature could be used to allow wake-on-lan at higher speeds.

2011-11-04netlink: validate NLA_MSECS lengthJohannes Berg1-0/+1
L2TP for example uses NLA_MSECS like this: policy: [L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, }, code: if (info->attrs[L2TP_ATTR_RECV_TIMEOUT]) cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]); As nla_get_msecs() is essentially nla_get_u64() plus the conversion to a HZ-based value, this will not properly reject attributes from userspace that aren't long enough and might overrun the message. Add NLA_MSECS to the attribute minlen array to check the size properly.

i825xx and xscale are "sub" Kconfigs to NET_VENDOR_INTEL, so NET_VENDOR_INTEL should contain ALL the dependencies of the "sub" Kconfigs. Same with 8390 is a "sub" Kconfig to NET_VENDOR_NATSEMI, so NET_VENDOR_NATSEMI needs to contains ALL the dependencies.

2011-11-04macvlan: receive multicast with local addressstephen hemminger1-0/+7
When implementing VRRP v2 using macvlan several problems were discovered. VRRP is weird in that all routers participating in a redundant group use the same virtual MAC address. Macvlan is a natural driver to use for this but it doesn't work. The problem is that packets with a macvlan device's source address are not received. The problem is actually a regression that date back almost 2 years now. The original problems started with: commit 618e1b7482f7a8a4c6c6e8ccbe140e4c331df4e9 Author: Arnd Bergmann <[email protected]> Date: Thu Nov 26 06:07:10 2009 +0000 macvlan: implement bridge, VEPA and private mode This patches restores the original 2.6.32 behavior.

2011-11-04tg3: Eliminate timer race with reset_taskMatt Carlson2-13/+2
During shutdown, it is impossible to reliably disable the timer and reset_task threads. Each thread can schedule the other, which leads to shutdown code that chases its tail. To fix the problem, this patch removes the ability of tg3_reset_task to schedule a new timer thread. To support this change, tg3_timer no longer terminates itself, but rather goes into a polling mode.

2011-11-04tg3: Schedule at most one tg3_reset_task runMatt Carlson2-9/+25
It is possible for multiple threads in the tg3 driver to each attempt to schedule a run of tg3_reset_task(). The multiple tg3_reset_task executions could all wind up on the same queue (and execute serially) or wind up on the queues of another processor (which could execute in parallel). Either scenario is not what was truly desired. This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to determine whether or not to schedule another run of tg3_reset_task(). With the new flag comes two new functions to facilitate scheduling and descheduling of tg3_reset_task().

2011-11-04tg3: Fix 4k tx bd segmentation codeMatt Carlson1-23/+24
The new 4k tx bd segmentation code had a bug in the error cleanup path. If the driver did not map all the physical fragments, the abort path would wind up advancing the producer index beyond the point where the setup code stopped. This would ultimately turn into a tx recovery error where the driver would expect the skb pointer to be set when it isn't. This patch fixes the problem, and then makes the code a little easier to understand.

2011-11-04tg3: Fix APE mutex init and useMatt Carlson2-24/+30
APE mutex register blocks are shared by all ports of multiport devices. For some mutexing purposes, each function is assigned their own register. For other cases, each function is assigned its own request and grant bits of a single register. For the latter cases, the tg3 driver is incorrectly allowing each function to use the same set of grant / request bits. This patch fixes the code so that each function uses the appropriate bitset.

2011-11-04PM / Freezer: Revert 27920651fe "PM / Freezer: Make fake_signal_wake_up() ↵Tejun Heo1-1/+1
wake TASK_KILLABLE tasks too" Commit 27920651fe "PM / Freezer: Make fake_signal_wake_up() wake TASK_KILLABLE tasks too" updated fake_signal_wake_up() used by freezer to wake up KILLABLE tasks. Sending unsolicited wakeups to tasks in killable sleep is dangerous as there are code paths which depend on tasks not waking up spuriously from KILLABLE sleep. For example. sys_read() or page can sleep in TASK_KILLABLE assuming that wait/down/whatever _killable can only fail if we can not return to the usermode. TASK_TRACED is another obvious example. The previous patch updated wait_event_freezekillable() such that it doesn't depend on the spurious wakeup. This patch reverts the offending commit. Note that the spurious KILLABLE wakeup had other implicit effects in KILLABLE sleeps in nfs and cifs and those will need further updates to regain freezekillable behavior.

freezer_do_not_count/freezer_count Commit 27920651fe "PM / Freezer: Make fake_signal_wake_up() wake TASK_KILLABLE tasks too" updated fake_signal_wake_up() used by freezer to wake up KILLABLE tasks. Sending unsolicited wakeups to tasks in killable sleep is dangerous as there are code paths which depend on tasks not waking up spuriously from KILLABLE sleep. For example. sys_read() or page can sleep in TASK_KILLABLE assuming that wait/down/whatever _killable can only fail if we can not return to the usermode. TASK_TRACED is another obvious example. The offending commit was to resolve freezer hang during system PM operations caused by KILLABLE sleeps in network filesystems. wait_event_freezekillable(), which depends on the spurious KILLABLE wakeup, was added by f06ac72e92 "cifs, freezer: add wait_event_freezekillable and have cifs use it" to be used to implement killable & freezable sleeps in network filesystems. To prepare for reverting of 27920651fe, this patch reimplements wait_event_freezekillable() using freezer_do_not_count/freezer_count() so that it doesn't depend on the spurious KILLABLE wakeup. This isn't very nice but should do for now.

2011-11-04USB: Update last_busy time after autosuspend failsAlan Stern1-0/+5
Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. A companion patch changes the PM core's behavior, but we also need to change the USB core. In particular, this patch (as1493) updates the device's last_busy time when an autosuspend fails, so that the PM core will retry the autosuspend in the future when the delay time expires again.

2011-11-04PM / Runtime: Automatically retry failed autosuspendsAlan Stern2-2/+26
Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. Therefore this patch (as1492) adds a mechanism for retrying failed autosuspends. If the callback routine updates the last_busy field so that the next autosuspend expiration time is in the future, the autosuspend will automatically be rescheduled.

2011-11-04PM / Sleep: Fix race between CPU hotplug and freezerSrivatsa S. Bhat1-0/+74
The CPU hotplug notifications sent out by the _cpu_up() and _cpu_down() functions depend on the value of the 'tasks_frozen' argument passed to them (which indicates whether tasks have been frozen or not). (Examples for such CPU hotplug notifications: CPU_ONLINE, CPU_ONLINE_FROZEN, CPU_DEAD, CPU_DEAD_FROZEN). Thus, it is essential that while the callbacks for those notifications are running, the state of the system with respect to the tasks being frozen or not remains unchanged, *throughout that duration*. Hence there is a need for synchronizing the CPU hotplug code with the freezer subsystem. Since the freezer is involved only in the Suspend/Hibernate call paths, this patch hooks the CPU hotplug code to the suspend/hibernate notifiers PM_[SUSPEND|HIBERNATE]_PREPARE and PM_POST_[SUSPEND|HIBERNATE] to prevent the race between CPU hotplug and freezer, thus ensuring that CPU hotplug notifications will always be run with the state of the system really being what the notifications indicate, _throughout_ their execution time.

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

2011-11-04IB/iser: DMA unmap TX bufs used for iSCSI/iSER headersOr Gerlitz2-4/+8
The current driver never does DMA unmapping on these buffers. Fix that by adding DMA unmapping to the task cleanup callback, and DMA mapping to the task init function (drop the headers_initialized micro-optimization).

2011-11-04IB/iser: Use separate buffers for the login request/responseOr Gerlitz3-15/+52
The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each.
