[tip:perf/urgent] perf/core: Force USER_DS when recording user stack data

by tip-bot for Yabin Cui

Commit-ID: 02e184476eff848273826c1d6617bb37e5bcc7ad Gitweb: https://git.kernel.org/tip/02e184476eff848273826c1d6617bb37e5bcc7ad Author: Yabin Cui <yabinc(a)google.com> AuthorDate: Thu, 23 Aug 2018 15:59:35 -0700 Committer: Ingo Molnar <mingo(a)kernel.org> CommitDate: Mon, 10 Sep 2018 14:01:46 +0200 perf/core: Force USER_DS when recording user stack data Perf can record user stack data in response to a synchronous request, such as a tracepoint firing. If this happens under set_fs(KERNEL_DS), then we end up reading user stack data using __copy_from_user_inatomic() under set_fs(KERNEL_DS). I think this conflicts with the intention of using set_fs(KERNEL_DS). And it is explicitly forbidden by hardware on ARM64 when both CONFIG_ARM64_UAO and CONFIG_ARM64_PAN are used. So fix this by forcing USER_DS when recording user stack data.

[PATCH AUTOSEL 4.18 001/131] tc-testing: flush gact actions on test teardown

by Sasha Levin

From: Vlad Buslov <vladbu(a)mellanox.com> [ Upstream commit 0c62f8a820b7fdeacf5ad9f9e24b53043d372c97 ] Test 6fb4 creates one mirred and one pipe action, but only flushes mirred on teardown.

[PATCH] ALSA: bebob: use address returned by kmalloc() instead of kernel stack for streaming DMA mapping

by Takashi Sakamoto

When executing 'fw_run_transaction()' with 'TCODE_WRITE_BLOCK_REQUEST', an address of 'payload' argument is used for streaming DMA mapping by 'firewire_ohci' module if 'size' argument is larger than 8 byte. Although in this case the address should not be on kernel stack, current implementation of ALSA bebob driver uses data in kernel stack for a cue to boot M-Audio devices. This often brings unexpected result, especially for a case of CONFIG_VMAP_STACK=y. This commit fixes the bug.

[PATCH net 01/13] net: sched: cls_u32: fix hnode refcounting

by Al Viro

From: Al Viro <viro(a)zeniv.linux.org.uk> cls_u32.c misuses refcounts for struct tc_u_hnode - it counts references via ->hlist and via ->tp_root together. u32_destroy() drops the former and, in case when there had been links, leaves the sucker on the list. As the result, there's nothing to protect it from getting freed once links are dropped. That also makes the "is it busy" check incapable of catching the root hnode - it *is* busy (there's a reference from tp), but we don't see it as something separate. "Is it our root?" check partially covers that, but the problem exists for others' roots as well. AFAICS, the minimal fix preserving the existing behaviour (where it doesn't include oopsen, that is) would be this: * count tp->root and tp_c->hlist as separate references. I.e. have u32_init() set refcount to 2, not 1. * in u32_destroy() we always drop the former; in u32_destroy_hnode() - the latter. That way we have *all* references contributing to refcount. List removal happens in u32_destroy_hnode() (called only when ->refcnt is 1) an in u32_destroy() in case of tc_u_common going away, along with everything reachable from it. IOW, that way we know that u32_destroy_key() won't free something still on the list (or pointed to by someone's ->root).

[PATCH 1/7] fix hnode refcounting

by Al Viro

From: Al Viro <viro(a)zeniv.linux.org.uk> cls_u32.c misuses refcounts for struct tc_u_hnode - it counts references via ->hlist and via ->tp_root together. u32_destroy() drops the former and, in case when there had been links, leaves the sucker on the list. As the result, there's nothing to protect it from getting freed once links are dropped. That also makes the "is it busy" check incapable of catching the root hnode - it *is* busy (there's a reference from tp), but we don't see it as something separate. "Is it our root?" check partially covers that, but the problem exists for others' roots as well. AFAICS, the minimal fix preserving the existing behaviour (where it doesn't include oopsen, that is) would be this: * count tp->root and tp_c->hlist as separate references. I.e. have u32_init() set refcount to 2, not 1. * in u32_destroy() we always drop the former; in u32_destroy_hnode() - the latter. That way we have *all* references contributing to refcount. List removal happens in u32_destroy_hnode() (called only when ->refcnt is 1) an in u32_destroy() in case of tc_u_common going away, along with everything reachable from it. IOW, that way we know that u32_destroy_key() won't free something still on the list (or pointed to by someone's ->root).

[PATCH] xen/netfront: fix waiting for xenbus state change

by Juergen Gross

Commit 822fb18a82aba ("xen-netfront: wait xenbus state change when load module manually") added a new wait queue to wait on for a state change when the module is loaded manually. Unfortunately there is no wakeup anywhere to stop that waiting. Instead of introducing a new wait queue rename the existing module_unload_q to module_wq and use it for both purposes (loading and unloading). As any state change of the backend might be intended to stop waiting do the wake_up_all() in any case when netback_changed() is called.

This would trigger when performing "perf" with a high NMI interrupt rate, while enabling and disabling function tracer. Ftrace uses breakpoints to convert the nops at the start of functions to calls to the function trampolines. The breakpoint traps disable interrupts and this makes calls into lockdep via the trace_hardirqs_off_thunk in the entry.S code. What happens is the following: do_idle { [interrupts enabled] <interrupt> [interrupts disabled] TRACE_IRQS_OFF [lockdep says irqs off] [...] TRACE_IRQS_IRET test if pt_regs say return to interrupts enabled [yes] TRACE_IRQS_ON [lockdep says irqs are on] <nmi> nmi_enter() { printk_nmi_enter() [traced by ftrace] [ hit ftrace breakpoint ] <breakpoint exception> TRACE_IRQS_OFF [lockdep says irqs off] [...] TRACE_IRQS_IRET [return from breakpoint] test if pt_regs say interrupts enabled [no] [iret back to interrupt] [iret back to code] tick_nohz_idle_enter() { lockdep_assert_irqs_enabled() [lockdep say no!] Although interrupts are indeed enabled, lockdep thinks it is not, and since we now do asserts via lockdep, it gives a false warning. The issue here is that printk_nmi_enter() is called before lockdep_off(), which disables lockdep (for this reason) in NMIs. By simply not allowing ftrace to see printk_nmi_enter() (via notrace annotation) we keep lockdep from getting confused.

[PULL RESEND v2 2/4] arm64: KVM: Only force FPEXC32_EL2.EN if trapping FPSIMD

by Christoffer Dall

From: Marc Zyngier <marc.zyngier(a)arm.com> If trapping FPSIMD in the context of an AArch32 guest, it is critical to set FPEXC32_EL2.EN to 1 so that the trapping is taken to EL2 and not EL1. Conversely, it is just as critical *not* to set FPEXC32_EL2.EN to 1 if we're not going to trap FPSIMD, as we then corrupt the existing VFP state. Moving the call to __activate_traps_fpsimd32 to the point where we know for sure that we are going to trap ensures that we don't set that bit spuriously.
