- fix BPF_LD|ABS|IND from negative offsets: make sure to sign extend lower 32 bits in 64-bit register before calling C helpers from JITed code, otherwise 'int k' argument of bpf_internal_load_pointer_neg_helper() function will be added as large unsigned integer, causing packet size check to trigger and abort the program. It's worth noting that JITed code for 'A = A op K' will affect upper 32 bits differently depending whether K is simm13 or not. Since small constants are sign extended, whereas large constants are stored in temp register and zero extended. That is ok and we don't have to pay a penalty of sign extension for every sethi, since all classic BPF instructions have 32-bit semantics and we only need to set correct upper bits when transitioning from JITed code into C. - though instructions 'A &= 0' and 'A *= 0' are odd, JIT compiler should not optimize them out Signed-off-by:

blk-mq uses percpu_ref for its usage counter which tracks the number of in-flight commands and used to synchronously drain the queue on freeze. percpu_ref shutdown takes measureable wallclock time as it involves a sched RCU grace period. This means that draining a blk-mq takes measureable wallclock time. One would think that this shouldn't matter as queue shutdown should be a rare event which takes place asynchronously w.r.t. userland. Unfortunately, SCSI probing involves synchronously setting up and then tearing down a lot of request_queues back-to-back for non-existent LUNs. This means that SCSI probing may take more than ten seconds when scsi-mq is used. This will be properly fixed by implementing a mechanism to keep q->mq_usage_counter in atomic mode till genhd registration; however, that involves rather big updates to percpu_ref which is difficult to apply late in the devel cycle (v3.17-rc6 at the moment). As a stop-gap ...

The "by8" implementation introduced in commit 22cddcc7 ("crypto: aes - AES CTR x86_64 "by8" AVX optimization") is failing crypto tests as it handles counter block overflows differently. It only accounts the right most 32 bit as a counter -- not the whole block as all other implementations do. This makes it fail the cryptomgr test #4 that specifically tests this corner case. As we're quite late in the release cycle, just disable the "by8" variant for now. Reported-by:

If the ccp is built as a built-in module, then ccp-crypto (whether built as a module or a built-in module) will be able to load and it will register its crypto algorithms. If the system does not have a CCP this will result in -ENODEV being returned whenever a command is attempted to be queued by the registered crypto algorithms. Add an API, ccp_present(), that checks for the presence of a CCP on the system. The ccp-crypto module can use this to determine if it should register it's crypto alogorithms.

In spite of what the GCC manual says, the -mfast-indirect-calls has never been supported in the 64-bit parisc compiler. Indirect calls have always been done using function descriptors irrespective of the -mfast-indirect-calls option. Recently, it was noticed that a function descriptor was always requested when the -mfast-indirect-calls option was specified. This caused problems when the option was used in application code and doesn't make any sense because the whole point of the option is to avoid using a function descriptor for indirect calls. Fixing this broke 64-bit kernel builds. I will fix GCC but for now we need the attached change. This results in the same kernel code as before. Signed-off-by:

Ring init and cleanup are not balanced because we re-init the rings on resume without having cleaned them up on suspend. This leads to the driver leaking the parser's hash tables with a kmemleak signature such as this: unreferenced object 0xffff880405960980 (size 32): comm "systemd-udevd", pid 516, jiffies 4294896961 (age 10202.044s) hex dump (first 32 bytes): d0 85 46 c0 ff ff ff ff 00 00 00 00 00 00 00 00 ..F............. 98 60 28 04 04 88 ff ff 00 00 00 00 00 00 00 00 .`(............. backtrace: [<ffffffff81816f9e>] kmemleak_alloc+0x4e/0xb0 [<ffffffff811fa678>] kmem_cache_alloc_trace+0x168/0x2f0 [<ffffffffc03e20a5>] i915_cmd_parser_init_ring+0x2a5/0x3e0 [i915] [<ffffffffc04088a2>] intel_init_ring_buffer+0x202/0x470 [i915] [<ffffffffc040c998>] intel_init_vebox_ring_buffer+0x1e8/0x2b0 [i915] [<ffffffffc03eff59>] i915_gem_init_hw+0x2f9/0x3a0 [i915] [<ffffffffc03f0057>] i915_gem_init+0x57/0x1d0 [i915] [<ffffffffc045e26a>] i915_driver_load+0xc0a/0x10e0 [i915] [<ffffffffc02e0d5d>] drm_dev_register+0xad/0x100 [drm] [<ffffffffc02e3b9f>] drm_get_pci_dev+0x8f/0x200 [drm] [<ffffffffc03c934b>] i915_pci_probe+0x3b/0x60 [i915] [<ffffffff81436725>] local_pci_probe+0x45/0xa0 [<ffffffff81437a69>] pci_device_probe+0xd9/0x130 [<ffffffff81524f4d>] driver_probe_device+0x12d/0x3e0 [<ffffffff815252d3>] __driver_attach+0x93/0xa0 [<ffffffff81522e1b>] bus_for_each_dev+0x6b/0xb0 This patch extends the current convention of checking whether a resource is already allocated before allocating it during ring init. Longer term it might make sense to only init the rings once. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=83794 Tested-by:
