| * inet: remove old fragmentation hash initializingHannes Frederic Sowa2013-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All fragmentation hash secrets now get initialized by their corresponding hash function with net_get_random_once. Thus we can eliminate the initial seeding. Also provide a comment that hash secret seeding happens at the first call to the corresponding hashing function. Cc: David S.

| * ipv6: split inet6_hash_frag for netfilter and initialize secrets with ↵Hannes Frederic Sowa2013-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | net_get_random_once Defer the fragmentation hash secret initialization for IPv6 like the previous patch did for IPv4. Because the netfilter logic reuses the hash secret we have to split it first. Thus introduce a new nf_hash_frag function which takes care to seed the hash secret. Cc: David S.

| * ipv4: initialize ip4_frags hash secret as late as possibleHannes Frederic Sowa2013-10-23
|/ | | | | | | | | | | | | | | | | | | Defer the generation of the first hash secret for the ipv4 fragmentation cache as late as possible. ip4_frags.rnd gets initial seeded by inet_frags_init and regulary reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly from ip_fragment.c in which case we initialize the secret directly. If we first get called by inet_frag_secret_rebuild we install a new secret by a manual call to get_random_bytes. This secret will be overwritten as soon as the first call to ipqhashfn happens. This is safe because we won't race while publishing the new secrets with anyone else. Cc: Eric Dumazet <edumazet@google.com> Cc: "David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The result of the store-clock-fast (STCKF) instruction is a bit fuzzy. It can happen that the value stored on one CPU is smaller than the value stored on another CPU, although the order of the stores is the other way around. This can cause deltas of get_tod_clock() values to become negative when they should not be. We need to be more careful with store-clock-fast, this patch partially reverts git commit e4b7b4238e666682555461fa52eecd74652f36bb "time: always use stckf instead of stck if available". The get_tod_clock() function now uses the store-clock-extended (STCKE) instruction. get_tod_clock_fast() can be used if the fuzziness of store-clock-fast is acceptable e.g. for wait loops local to a CPU.

This callback is pkg_temp_thermal_platform_thermal_notify. Here to avoid multiple interrupts from cores in a package, we disable the source and also set a variable to avoid scheduling delayed work function. This variable is protected via spin_lock_irqsave. On one buggy platform, we still receiving interrupts even if the source is disabled. This can cause deadlock/lockdep warning, when interrupt is generated while under spinlock in work function. Change spin_lock to spin_lock_irqsave and spin_unlock to spin_unlock_irqrestore as the data it is trying to protect can also be modified in a notification call called from interrupt handler.

The resulting wrong test prevents thermal_zone_device_update() call, which calls handlers for situation when trip points are passed. Such behavior prevents thermal driver from proper reaction (when TMU interrupt is raised) in a situation when overheating is detected at TMU hardware. It turns out, that after exynos thermal subsystem redesign (at v3.12) this check is not needed, since it is not possible to register thermal zone without valid thermal device.

| | * | | [media] s5p-jpeg: Initialize vfd_decoder->vfl_dir fieldJacek Anaszewski2013-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes regression introduced in commit 5c77879ff9ab9e7 "[media] v4l2-dev: add new VFL_DIR_ defines" caused by not initializing the vfl_dir field of the vfd_decoder instance of struct video_device, after the field was introduced. It precluded calling the driver's ioctls which require vfl_dir not to be equal to VFL_DIR_RX which is defined as 0 and uninitialized vfl_dir field is interpreted as such. In effect the test in the v4l_s_fmt function failed for the ioctls that expect is_tx to be false, which prevented the ioctl callbacks registered by the driver from being called.

This was just a special case. Commit e15dab752d4c588544ccabdbe020a7cc092e23c8 introduced correct support for converting userpage to dma address, but unfortunately it broke the support for simple dma address = physical address for the case, when given physical frame has no struct page associated with it (this happens if one use for example dma_declare_coherent api or other reserved memory approach). This commit restores support for such cases.

According to Smatch, it's not always clear if the IRQs are enabled or disabled when we return. It turns out this function is always called with IRQs enabled and we can just use spin_lock_irq(). It's called from __enqueue_in_driver().

That register was likely set by firmware itself which means it could not contain reasonable values until firmware is up and running. Usually it just worked as some garbage value was returned accidentally but it appears that in some cases returned garbage value was 0x00 which was considered "firmware is up and running" by the driver and firmware loading was skipped leaving device to non-working state. Fix problem by removing unreliable check and let the driver keep count whether firmware is loaded or not.
