2011-11-04ARM: OMAP: change get_context_loss_count ret value to intTomi Valkeinen9-20/+36
get_context_loss_count functions return context loss count as u32, and zero means an error. However, zero is also returned when context has never been lost and could also be returned when the context loss count has wrapped and goes to zero. Change the functions to return an int, with negative value meaning an error. OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the hsmmc code handles the returned value as an int, with negative value meaning an error, this patch actually fixes hsmmc code also.

2011-11-04ARM: OMAP3: hwmod: fix variant registration and remove SmartReflex from ↵Paul Walmsley1-2/+2
common list Commit d6504acd2125984c61dce24727dd3842d0144015 ("OMAP2+: hwmod: remove OMAP_CHIP*") tests the inverse condition of what it should be testing for the return value from omap_hwmod_register(). This causes several IP blocks to not be registered on several OMAP3 family devices. Fixing that bug also unmasked another bug, originally reported by Chase Maupin <[email protected]> and then subsequently by Abhilash K V <[email protected]>, which caused SmartReflex IP blocks to be registered on SoCs that don't support them. Thanks to Russell King - ARM Linux <[email protected]> for comments on a previous version of the patch.

2011-11-04ARM: OMAP: I2C: Fix omap_register_i2c_bus() return value on successLaurent Pinchart1-1/+1
Commit 4d17aeb1c5b2375769446d13012a98e6d265ec13 ("OMAP: I2C: split device registration and convert OMAP2+ to omap_device") makes omap2_i2c_add_bus() return a pointer to an omap_device instead on success instead of 0. This breaks the omap_register_i2c_bus() ABI and results in the igep0020 board code detecting an I2C bus registration error when there is none. Fix the problem by using PTR_RET() instead of PTR_ERR() in omap2_i2c_add_bus().

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.

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.

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.

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.

However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend).

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.
