f76be61 Andi Kleen 01 April 2016, 21:31:40 UTC Make CONFIG_FHANDLE default y Newer Fedora and OpenSUSE didn't boot with my standard configuration. It took me some time to figure out why, in fact I had to write a script to try different config options systematically. The problem is that something (systemd) in dracut depends on CONFIG_FHANDLE, which adds open by file handle syscalls. While it is set in defconfigs it is very easy to miss when updating older configs because it is not default y. Make it default y and also depend on EXPERT, as dracut use is likely widespread.

af8e15c Michal Hocko 01 April 2016, 21:31:34 UTC oom, oom_reaper: do not enqueue task if it is on the oom_reaper_list head Commit bb29902a7515 ("oom, oom_reaper: protect oom_reaper_list using simpler way") has simplified the check for tasks already enqueued for the oom reaper by checking tsk->oom_reaper_list != NULL. This check is not sufficient because the tsk might be the head of the queue without any other tasks queued and then we would simply lockup looping on the same task. Fix the condition by checking for the head as well.

858eaaa Nadav Amit 01 April 2016, 21:31:26 UTC mm/rmap: batched invalidations should use existing api The recently introduced batched invalidations mechanism uses its own mechanism for shootdown. However, it does wrong accounting of interrupts (e.g., inc_irq_stat is called for local invalidations), trace-points (e.g., TLB_REMOTE_SHOOTDOWN for local invalidations) and may break some platforms as it bypasses the invalidation mechanisms of Xen and SGI UV. This patch reuses the existing TLB flushing mechnaisms instead. We use NULL as mm to indicate a global invalidation is required.

a7657f1 Giuseppe CAVALLARO 01 April 2016, 07:07:16 UTC stmmac: fix MDIO settings Initially the phy_bus_name was added to manipulate the driver name but it was recently just used to manage the fixed-link and then to take some decision at run-time. So the patch uses the is_pseudo_fixed_link and removes the phy_bus_name variable not necessary anymore. The driver can manage the mdio registration by using phy-handle, dwmac-mdio and own parameter e.g. snps,phy-addr. This patch takes care about all these possible configurations and fixes the mdio registration in case of there is a real transceiver or a switch (that needs to be managed by using fixed-link).

Since the fix in f91ff5b9ff52 ("net: sk_{detach|attach}_filter() rcu fixes") sk_attach_filter()/sk_detach_filter() now dereferences the filter with rcu_dereference_protected(), checking whether socket lock is held in control path. Since its introduction in 994051625981 ("tun: socket filter support"), tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the sock_owned_by_user(sk) doesn't apply in this specific case and therefore triggers the false positive. Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair that is used by tap filters and pass in lockdep_rtnl_is_held() for the rcu_dereference_protected() checks instead.

4a07083 Takashi Iwai 01 April 2016, 10:28:16 UTC ALSA: timer: Use mod_timer() for rearming the system timer ALSA system timer backend stops the timer via del_timer() without sync and leaves del_timer_sync() at the close instead. This is because of the restriction by the design of ALSA timer: namely, the stop callback may be called from the timer handler, and calling the sync shall lead to a hangup. However, this also triggers a kernel BUG() when the timer is rearmed immediately after stopping without sync: kernel BUG at kernel/time/timer.c:966! Call Trace: <IRQ> [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0 [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0 [<ffffffff8122fca0>] ? debug_check_no_locks_freed+0x290/0x290 [<ffffffff8239ec64>] snd_timer_s_function+0xb4/0x120 [<ffffffff81296b72>] call_timer_fn+0x162/0x520 [<ffffffff81296add>] ? call_timer_fn+0xcd/0x520 [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0 .... It's the place where add_timer() checks the pending timer. It's clear that this may happen after the immediate restart without sync in our cases. So, the workaround here is just to use mod_timer() instead of add_timer(). This looks like a band-aid fix, but it's a right move, as snd_timer_interrupt() takes care of the continuous rearm of timer.

14ebda3 Paolo Bonzini 29 March 2016, 15:56:57 UTC KVM: x86: reduce default value of halt_poll_ns parameter Windows lets applications choose the frequency of the timer tick, and in Windows 10 the maximum rate was changed from 1024 Hz to 2048 Hz. Unfortunately, because of the way the Windows API works, most applications who need a higher rate than the default 64 Hz will just do timeGetDevCaps(&tc, sizeof(tc)); timeBeginPeriod(tc.wPeriodMin); and pick the maximum rate. This causes very high CPU usage when playing media or games on Windows 10, even if the guest does not actually use the CPU very much, because the frequent timer tick causes halt_poll_ns to kick in. There is no really good solution, especially because Microsoft could sooner or later bump the limit to 4096 Hz, but for now the best we can do is lower a bit the upper limit for halt_poll_ns. :-( Reported-by: Jon Panozzo <jonp@lime-technology.com> Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> 01 April 2016, 10:10:10 UTC

321c565 Yuki Shibuya 24 March 2016, 05:17:03 UTC KVM: x86: Inject pending interrupt even if pending nmi exist Non maskable interrupts (NMI) are preferred to interrupts in current implementation. If a NMI is pending and NMI is blocked by the result of nmi_allowed(), pending interrupt is not injected and enable_irq_window() is not executed, even if interrupts injection is allowed. In old kernel (e.g. 2.6.32), schedule() is often called in NMI context. In this case, interrupts are needed to execute iret that intends end of NMI. The flag of blocking new NMI is not cleared until the guest execute the iret, and interrupts are blocked by pending NMI. Due to this, iret can't be invoked in the guest, and the guest is starved until block is cleared by some events (e.g. canceling injection). This patch injects pending interrupts, when it's allowed, even if NMI is blocked. And, If an interrupts is pending after executing inject_pending_event(), enable_irq_window() is executed regardless of NMI pending counter.

However, since upstream bootloaders don't initialize the chip specifically, they leave the fiber MII's PDOWN flag set, which means that the CPU port doesn't connect. This patch checks whether this flag has been clear prior by something else, and if not make us clear it.

While we have a fixup patch for it already, the usage of those new functions are needed only when we share data with other drivers. So, better to revert the changes.

However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption.

Tushar fixes an issue which was introduced with an earlier commit, where hardware register RAR0 default MAC address does not get set properly. Alex fixes two issues, first being the VXLAN port number should be stored in network order instead of in host order. The second fix corrects the ATR code to handle IPv6 extension headers. The issue was ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through, but that is not the case, which resulted in bad filters being setup. Mark fixes a use of usleep_range() to udelay() in the case where a lock is being held. Stefan fixes the offline self tests where ndo_stop() should be used instead of ndo_close(), which causes IFF_UP to be cleared and interface routes get removed. Emil fixes the error case where we need to return an error when a MAC address change is rejected by the PF. This helps prevent the user from modifying the MAC address when the operation is not permitted. Sridhar provides three fixes for ixgbe, all dealing with traffic class offload handling. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 31 March 2016, 15:40:16 UTC
