Since commit feb44f1f (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC. This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by disabling Xen support in this configuration. Users needing Xen support in a non-SMP i386 kernel will need to enable CONFIG_X86_UP_APIC. Signed-off-by: NDavid Vrabel <david.vrabel@citrix.com> Cc: <stable@vger.kernel.org>

Merge tag 'asoc-v4.2-disable-topology' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Disable topology support for v4.2 The topology code merged in the v4.2 merge window introduced a new ABI which was believed to be suitable for use but subsequently additional work by the developers of this feature have revealed some problems that need to be addressed. In order to allow this to be done without having to support the initial ABI add Kconfig to disable the build and also add some #error statements to the UAPI header so users can't use them.

The fix for deadlock in PM in commit [1ee23fe0: ALSA: usb-audio: Fix deadlocks at resuming] introduced a new check of in_pm flag. However, the brainless patch author evaluated it in a wrong way (logical AND instead of logical OR), thus usb_autopm_get_interface() is wrongly called at probing, leading to unbalance of runtime PM refcount. This patch fixes it by correcting the logic.

REPORT LUNS should not fail just because the allocation length is less than 16. The relevant section of SPC-4 is: 4.2.5.6 Allocation length The ALLOCATION LENGTH field specifies the maximum number of bytes or blocks that an application client has allocated in the Data-In Buffer. The ALLOCATION LENGTH field specifies bytes unless a different requirement is stated in the command definition. An allocation length of zero specifies that no data shall be transferred. This condition shall not be considered an error. So we should just truncate our response rather than return an error.

The object tt_local is allocated with kmalloc and not initialized when the function batadv_tt_local_add checks for the vlan. But this function can only cleanup the object when the (not yet initialized) reference counter of the object is 1. This is unlikely and thus the object would leak when the vlan could not be found. Instead the uninitialized object tt_local has to be freed manually and the pointer has to set to NULL to avoid calling the function which would try to decrement the reference counter of the not existing object.

Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

VxLAN offloading is not functional if the NIC is running in multichannel mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole connectivity through the NIC and the device needs to be down and up to restore it. The firmware should take care about it and does not allow the conversion of interface to tunnel type (be_cmd_manage_iface) or should support VxLAN offloading if multichannel config is enabled. I have tested this on the latest available firmware (10.6.144.21).

rt6_make_pcpu_route() is called under read_lock(&table->tb6_lock). rt6_make_pcpu_route() calls ip6_rt_pcpu_alloc(rt) which then calls dst_alloc(). dst_alloc() _may_ call ip6_dst_gc() which takes the write_lock(&tabl->tb6_lock). A visualized version: read_lock(&table->tb6_lock); rt6_make_pcpu_route(); => ip6_rt_pcpu_alloc(); => dst_alloc(); => ip6_dst_gc(); => write_lock(&table->tb6_lock); /* oops */ The fix is to do a read_unlock first before calling ip6_rt_pcpu_alloc().

It is a prep work for fixing a potential deadlock when creating a pcpu rt. The current rt6_get_pcpu_route() will also create a pcpu rt if one does not exist.

PPP devices may get automatically unregistered when their network namespace is getting removed. This happens if the ppp control plane daemon (e.g. pppd) exits while it is the last user of this namespace. This leads to several races: * ppp_exit_net() may destroy the per namespace idr (pn->units_idr) before all file descriptors were released. Successive ppp_release() calls may then cleanup PPP devices with ppp_shutdown_interface() and try to use the already destroyed idr. * Automatic device unregistration may also happen before the ppp_release() call for that device gets executed. Once called on the file owning the device, ppp_release() will then clean it up and try to unregister it a second time. To fix these issues, operations defined in ppp_shutdown_interface() are moved to the PPP device's ndo_uninit() callback. This allows PPP devices to be properly cleaned up by unregister_netdev() and friends. So checking for ppp->owner is now an accurate test to decide if a PPP device should be unregistered. Setting ppp->owner is done in ppp_create_interface(), before device registration, in order to avoid unprotected modification of this field. Finally, ppp_exit_net() now starts by unregistering all remaining PPP devices to ensure that none will get unregistered after the call to idr_destroy().

Commit 8133534c ("net: limit tcp/udp rmem/wmem to SOCK_{RCV,SND}BUF_MIN") modified four sysctls to enforce that the values written to them are not less than SOCK_MIN_{RCV,SND}BUF. That change causes 4096 to no longer be accepted as a valid value for 'min' in tcp_wmem and udp_wmem_min. 4096 has been the default for both of those sysctls for a long time, and unfortunately seems to be an extremely popular setting. This change breaks a large number of sysctl configurations at Facebook. That commit referred to b1cb59cf ("net: sysctl_net_core: check SNDBUF and RCVBUF for min length"), which choose to use the SOCK_MIN constants as the lower limits to avoid nasty bugs. But AFAICS, a limit of SOCK_MIN_SNDBUF isn't necessary to do that: the BUG_ON cited in the commit message seems to have happened because unix_stream_sendmsg() expects a minimum of a full page (ie SK_MEM_QUANTUM) and the math broke, not because it had less than SOCK_MIN_SNDBUF allocated. This particular issue doesn't seem to affect TCP however: using a setting of "1 1 1" for tcp_{r,w}mem works, although it's obviously suboptimal. SK_MEM_QUANTUM would be a nice minimum, but it's 64K on some archs, so there would still be breakage. Since a value of one doesn't seem to cause any problems, we can drop the minimum 8133534c added to fix this. This reverts commit 8133534c.

This patch increments privatecnt value and set DMA_PRIVATE in device caps in dma_request_slave_channel() function. This is needed to keep privatecnt increment/decrement balance. As function dma_release_channel() decrements privatecnt counter, we need to increment it when channel is requested. Otherwise privatecnt drops into negatives after few dma_release_channel() calls.
