2014-06-26recordmcount/MIPS: Fix possible incorrect mcount_loc table entries in modulesAlex Smith
On MIPS calls to _mcount in modules generate 2 instructions to load the _mcount address (and therefore 2 relocations). The mcount_loc table should only reference the first of these, so the second is filtered out by checking the relocation offset and ignoring ones that immediately follow the previous one seen. However if a module has an _mcount call at offset 0, the second relocation would not be filtered out due to old_r_offset == 0 being taken to mean that the current relocation is the first one seen, and both would end up in the mcount_loc table. This results in ftrace_make_nop() patching both (adjacent) instructions to branches over the _mcount call sequence like so: 0xffffffffc08a8000: 04 00 00 10 b 0xffffffffc08a8014 0xffffffffc08a8004: 04 00 00 10 b 0xffffffffc08a8018 0xffffffffc08a8008: 2d 08 e0 03 move at,ra ... The second branch is in the delay slot of the first, which is defined to be unpredictable - on the platform on which this bug was encountered, it triggers a reserved instruction exception. Fix by initializing old_r_offset to ~0 and using that instead of 0 to determine whether the current relocation is the first seen.

2014-06-26MIPS: BPF JIT: Fix build error.Daniel Borkmann
mips: allmodconfig fails in 3.16-rc1 with lots of undefined symbols. arch/mips/net/bpf_jit.c: In function 'is_load_to_a': arch/mips/net/bpf_jit.c:559:7: error: 'BPF_S_LD_W_LEN' undeclared (first use in this function) arch/mips/net/bpf_jit.c:559:7: note: each undeclared identifier is reported only once for each function it appears in arch/mips/net/bpf_jit.c:560:7: error: 'BPF_S_LD_W_ABS' undeclared (first use in this function) [...] The reason behind this is that 3480593131e0 ("net: filter: get rid of BPF_S_* enum") was routed via net-next tree, that takes all BPF-related changes, at a time where MIPS BPF JIT was not part of net-next, while c6610de353da ("MIPS: net: Add BPF JIT") was routed via mips arch tree and went into mainline within the same merge window. Thus, fix it up by converting BPF_S_* in a similar fashion as in 3480593131e0 for MIPS.

2014-06-26Revert "MIPS: Save/restore MSA context around signals"Paul Burton
This reverts commit eec43a224cf1 "MIPS: Save/restore MSA context around signals" and the MSA parts of ca750649e08c "MIPS: kernel: signal: Prevent save/restore FPU context in user memory" (the restore path of which appears incorrect anyway...). The reverted patch took care not to break compatibility with userland users of struct sigcontext, but inadvertantly changed the offset of the uc_sigmask field of struct ucontext. Thus Linux v3.15 breaks the userland ABI. The MSA context will need to be saved via some other opt-in mechanism, but for now revert the change to reduce the fallout. This will have minimal impact upon use of MSA since the only supported CPU which includes it (the P5600) is 32-bit and therefore requires that the experimental CONFIG_MIPS_O32_FP64_SUPPORT Kconfig option be selected before the kernel will set FR=1 for a task, a requirement for MSA use. Thus the users of MSA are limited to known small groups of people & this patch won't be breaking any previously working MSA-using userland outside of experimental settings.

2014-06-26ALSA: usb-audio: Fix races at disconnection and PCM closingTakashi Iwai
When a USB-audio device is disconnected while PCM is still running, we still see some race: the disconnect callback calls snd_usb_endpoint_free() that calls release_urbs() and then kfree() while a PCM stream would be closed at the same time and calls stop_endpoints() that leads to wait_clear_urbs(). That is, the EP object might be deallocated while a PCM stream is syncing with wait_clear_urbs() with the same EP. Basically calling multiple wait_clear_urbs() would work fine, also calling wait_clear_urbs() and release_urbs() would work, too, as wait_clear_urbs() just reads some fields in ep. The problem is the succeeding kfree() in snd_pcm_endpoint_free(). This patch moves out the EP deallocation into the later point, the destructor callback. At this stage, all PCMs must have been already closed, so it's safe to free the objects.

2014-06-25ipv4: fix dst race in sk_dst_get()Eric Dumazet
When IP route cache had been removed in linux-3.6, we broke assumption that dst entries were all freed after rcu grace period. DST_NOCACHE dst were supposed to be freed from dst_release(). But it appears we want to keep such dst around, either in UDP sockets or tunnels. In sk_dst_get() we need to make sure dst refcount is not 0 before incrementing it, or else we might end up freeing a dst twice. DST_NOCACHE set on a dst does not mean this dst can not be attached to a socket or a tunnel. Then, before actual freeing, we need to observe a rcu grace period to make sure all other cpus can catch the fact the dst is no longer usable.

Commit 3f85944fe207d0225ef21a2c0951d4946fc9a95d ("net: Add sysfs file for port number") introduce dev_port to network devices. cxgb4 adapters have multiple ports on the same PCI function, and used dev_id to identify those ports. That use was removed by commit 8c367fcbe6549195d2eb11e62bea233f811aad41 ("cxgb4: Do not set net_device::dev_id to VI index"), since dev_id should be used only when devices share the same MAC address.

2014-06-25xen-netback: bookkeep number of active queues in our own moduleWei Liu
The original code uses netdev->real_num_tx_queues to bookkeep number of queues and invokes netif_set_real_num_tx_queues to set the number of queues. However, netif_set_real_num_tx_queues doesn't allow real_num_tx_queues to be smaller than 1, which means setting the number to 0 will not work and real_num_tx_queues is untouched. This is bogus when xenvif_free is invoked before any number of queues is allocated. That function needs to iterate through all queues to free resources. Using the wrong number of queues results in NULL pointer dereference. So we bookkeep the number of queues in xen-netback to solve this problem. This fixes a regression introduced by multiqueue patchset in 3.16-rc1. There's another bug in original code that the real number of RX queues is never set. In current Xen multiqueue design, the number of TX queues and RX queues are in fact the same. We need to set the numbers of TX and RX queues to the same value. Also remove xenvif_select_queue and leave queue selection to core driver, as suggested by David Miller.

2014-06-25ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13Takashi Iwai
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).

2014-06-25blk-mq: blk_mq_start_hw_queue() should use blk_mq_run_hw_queue()Jens Axboe
Currently it calls __blk_mq_run_hw_queue(), which depends on the CPU placement being correct. This means it's not possible to call blk_mq_start_hw_queues(q) from a context that is correct for all queues, leading to triggering the WARN_ON(!cpumask_test_cpu(raw_smp_processor_id(), hctx->cpumask)); in __blk_mq_run_hw_queue().

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing cleanups and fixes from Steven Rostedt: "This includes three patches from Oleg Nesterov. The first is a fix to a race condition that happens between enabling/disabling syscall tracepoints and new process creations (the check to go into the ptrace path for a process can be set when it shouldn't, or not set when it should). Not a major bug but one that should be fixed and even applied to stable. The other two patches are cleanup/fixes that are not that critical, but for an -rc1 release would be nice to have. They both deal with syscall tracepoints. It also includes a patch to introduce a new macro for the TRACE_EVENT() format called __field_struct(). Originally, __field() was used to record any variable into a trace event, but with the addition of setting the "is signed" attribute, the check causes anything but a primitive variable to fail to compile. That is, structs and unions can't be used as they once were. When the "is signed" check was introduce there were only primitive variables being recorded. But that will change soon and it was reported that __field() causes build failures. To solve the __field() issue, __field_struct() is introduced to allow trace_events to be able to record complex types too" * tag 'trace-fixes-v3.16-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Add __field_struct macro for TRACE_EVENT() tracing: syscall_regfunc() should not skip kernel threads tracing: Change syscall_*regfunc() to check PF_KTHREAD and use for_each_process_thread() tracing: Fix syscall_*regfunc() vs copy_process() race
2014-06-25misc: atmel_pwm: fix Kconfig symbolsNicolas Ferre
AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this patch changes them to their correct ARCH_* version. These symbols are chosen instead of the SOC_* ones because this driver is not converted to DT. Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon, during the move to the PWM sub-system.

2014-06-25powerpc/module: Fix TOC symbol CRCLaurent Dufour
The commit 71ec7c55ed91 introduced the magic symbol ".TOC." for ELFv2 ABI. This symbol is built manually and has no CRC value computed. A zero value is put in the CRC section to avoid modpost complaining about a missing CRC. Unfortunately, this breaks the kernel module loading when the kernel is relocated (kdump case for instance) because of the relocation applied to the kcrctab values. This patch compute a CRC value for the TOC symbol which will match the one compute by the kernel when it is relocated - aka '0 - relocate_start' done in maybe_relocated called by check_version (module.c).
