2013-01-0688pm860x_battery: Eliminate possible references to released resourcesJulia Lawall
devm_kzalloc should not be followed by kfree, as this results in a double free. The problem was found using the following semantic match (http://coccinelle.lip6.fr/): // <smpl> @@ expression x,e; @@ x = devm_kzalloc(...) ... when != x = e ?-kfree(x,...); // </smpl> Furthermore, in the remove function, the calls to free_irq are moved up to prevent a possible reference in the interrupt handler to resources freed by power_supply_unregister.

2013-01-05power_supply: Add watchdog and safety timer expiries under PROP_HEALTH_*Ramakrishna Pallala
As most of the charger chips come with two kinds of safety features related to timing: 1. Watchdog Timer (interms of seconds/mins) 2. Safety Timer (interms of hours) This patch adds these to fault causes in POWER_SUPPLY_PROP_HEALTH_* enums so that whenever there is either watchdog timeout or safety timer timeout driver could notify the user space accurately about the fault and will also be helpful for debug.

2013-01-05charger_manager: Don't use [delayed_]work_pending()Tejun Heo
There's no need to test whether a (delayed) work item in pending before queueing, flushing or cancelling it. Most uses are unnecessary and quite a few of them are buggy. Remove unnecessary pending tests and rewrite _setup_polling() so that it uses mod_delayed_work() if the next polling interval is sooner than currently scheduled. queue_delayed_work() is used otherwise. Only compile tested. I noticed that two work items - setup_polling and cm_monitor_work - schedule each other. It's a very unusual construct and I'm fairly sure it's racy. You can't break such circular dependency by calling cancel on each. I strongly recommend revising the mechanism.

2013-01-02leds: leds-gpio: set devm_gpio_request_one() flags param correctlyJavier Martinez Canillas
commit a99d76f leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

2013-01-02tmpfs mempolicy: fix /proc/mounts corrupting memoryHugh Dickins
Recently I suggested using "mount -o remount,mpol=local /tmp" in NUMA mempolicy testing. Very nasty. Reading /proc/mounts, /proc/pid/mounts or /proc/pid/mountinfo may then corrupt one bit of kernel memory, often in a page table (causing "Bad swap" or "Bad page map" warning or "Bad pagetable" oops), sometimes in a vm_area_struct or rbnode or somewhere worse. "mpol=prefer" and "mpol=prefer:Node" are equally toxic. Recent NUMA enhancements are not to blame: this dates back to 2.6.35, when commit e17f74af351c "mempolicy: don't call mpol_set_nodemask() when no_context" skipped mpol_parse_str()'s call to mpol_set_nodemask(), which used to initialize v.preferred_node, or set MPOL_F_LOCAL in flags. With slab poisoning, you can then rely on mpol_to_str() to set the bit for node 0x6b6b, probably in the next page above the caller's stack. mpol_parse_str() is only called from shmem_parse_options(): no_context is always true, so call it unused for now, and remove !no_context code. Set v.nodes or v.preferred_node or MPOL_F_LOCAL as mpol_to_str() might expect. Then mpol_to_str() can ignore its no_context argument also, the mpol being appropriately initialized whether contextualized or not. Rename its no_context unused too, and let subsequent patch remove them (that's not needed for stable backporting, which would involve rejects). I don't understand why MPOL_LOCAL is described as a pseudo-policy: it's a reasonable policy which suffers from a confusing implementation in terms of MPOL_PREFERRED with MPOL_F_LOCAL. I believe this would be much more robust if MPOL_LOCAL were recognized in switch statements throughout, MPOL_F_LOCAL deleted, and MPOL_PREFERRED use the (possibly empty) nodes mask like everyone else, instead of its preferred_node variant (I presume an optimization from the days before MPOL_LOCAL). But that would take me too long to get right and fully tested. Signed-off-by: Hugh Dickins <hughd@google.com> Cc: stable@vger.kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-01-02epoll: prevent missed events on EPOLL_CTL_MODEric Wong
EPOLL_CTL_MOD sets the interest mask before calling f_op->poll() to ensure events are not missed. Since the modifications to the interest mask are not protected by the same lock as ep_poll_callback, we need to ensure the change is visible to other CPUs calling ep_poll_callback. We also need to ensure f_op->poll() has an up-to-date view of past events which occured before we modified the interest mask. So this barrier also pairs with the barrier in wq_has_sleeper(). This should guarantee either ep_poll_callback or f_op->poll() (or both) will notice the readiness of a recently-ready/modified item.

2012-12-28mm: fix null pointer dereference in wait_iff_congested()Zlatko Calusic
An unintended consequence of commit 4ae0a48b5efc ("mm: modify pgdat_balanced() so that it also handles order-0") is that wait_iff_congested() can now be called with NULL 'struct zone *' producing kernel oops like this: BUG: unable to handle kernel NULL pointer dereference IP: [<ffffffff811542d9>] wait_iff_congested+0x59/0x140 This trivial patch fixes it.

2012-12-27libceph: fix protocol feature mismatch failure pathSage Weil
We should not set con->state to CLOSED here; that happens in ceph_fault() in the caller, where it first asserts that the state is not yet CLOSED. Avoids a BUG when the features don't match. Since the fail_protocol() has become a trivial wrapper, replace calls to it with direct calls to reset_connection().

2012-12-27libceph: WARN, don't BUG on unexpected connection statesAlex Elder
A number of assertions in the ceph messenger are implemented with BUG_ON(), killing the system if connection's state doesn't match what's expected. At this point our state model is (evidently) not well understood enough for these assertions to trigger a BUG(). Convert all BUG_ON(con->state...) calls to be WARN_ON(con->state...) so we learn about these issues without killing the machine. We now recognize that a connection fault can occur due to a socket closure at any time, regardless of the state of the connection. So there is really nothing we can assert about the state of the connection at that point so eliminate that assertion.
