Given we have uninitialized list_heads being passed to list_add() it will always be the case that those uninitialized values randomly trigger the poison value. Especially since a list_add() operation will seed the stack with the poison value for later stack allocations to trip over. For example, see these two false positive reports: list_add attempted on force-poisoned entry WARNING: at lib/list_debug.c:34 [..] NIP [c00000000043c390] __list_add+0xb0/0x150 LR [c00000000043c38c] __list_add+0xac/0x150 Call Trace: __list_add+0xac/0x150 (unreliable) __down+0x4c/0xf8 down+0x68/0x70 xfs_buf_lock+0x4c/0x150 [xfs] list_add attempted on force-poisoned entry(0000000000000500), new->next == d0000000059ecdb0, new->prev == 0000000000000500 WARNING: at lib/list_debug.c:33 [..] NIP [c00000000042db78] __list_add+0xa8/0x140 LR [c00000000042db74] __list_add+0xa4/0x140 Call Trace: __list_add+0xa4/0x140 (unreliable) rwsem_down_read_failed+0x6c/0x1a0 down_read+0x58/0x60 xfs_log_commit_cil+0x7c/0x600 [xfs] Fixes: commit 5c2c2587 ("mm, dax, pmem: introduce {get|put}_dev_pagemap() for dax-gup") Signed-off-by:

Commit e1534ae9 ("mm: differentiate page_mapped() from page_mapcount() for compound pages") changed the famous BUG_ON(page_mapped(page)) in __delete_from_page_cache() to VM_BUG_ON_PAGE(page_mapped(page)): which gives us more info when CONFIG_DEBUG_VM=y, but nothing at all when not. Although it has not usually been very helpul, being hit long after the error in question, we do need to know if it actually happens on users' systems; but reinstating a crash there is likely to be opposed :) In the non-debug case, pr_alert("BUG: Bad page cache") plus dump_page(), dump_stack(), add_taint() - I don't really believe LOCKDEP_NOW_UNRELIABLE, but that seems to be the standard procedure now. Move that, or the VM_BUG_ON_PAGE(), up before the deletion from tree: so that the unNULLified page->mapping gives a little more information. If the inode is being evicted (rather than truncated), it won't have any vmas left, so it's safe(ish) to assume that the raised mapcount is erroneous, and we can discount it from page_count to avoid leaking the page (I'm less worried by leaking the occasional 4kB, than losing a potential 2MB page with each 4kB page leaked).

The warning message "killed due to inadequate hugepage pool" simply indicates that SIGBUS was sent, not that the process was forcibly killed. If the process has a signal handler installed does not fix the problem, this message can rapidly spam the kernel log. On my amd64 dev machine that does not have hugepages configured, I can reproduce the repeated warnings easily by setting vm.nr_hugepages=2 (i.e., 4 megabytes of huge pages) and running something that sets a signal handler and forks, like #include <sys/mman.h> #include <signal.h> #include <stdlib.h> #include <unistd.h> sig_atomic_t counter = 10; void handler(int signal) { if (counter-- == 0) exit(0); } int main(void) { int status; char *addr = mmap(NULL, 4 * 1048576, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS | MAP_HUGETLB, -1, 0); if (addr == MAP_FAILED) {perror("mmap"); return 1;} *addr = 'x'; switch (fork()) { case -1: perror("fork"); return 1; case 0: signal(SIGBUS, handler); *addr = 'x'; break; default: *addr = 'x'; wait(&status); if (WIFSIGNALED(status)) { psignal(WTERMSIG(status), "child"); } break; } } Signed-off-by:

Pull sound fixes from Takashi Iwai: "It's always an ambivalent feeling to send a large pull request at the late stage like this, especially when most of patches came from me. Anyway, this is a collection of lots of small fixes that slipped from the previous pull request. All fixes are about ASoC, and the majority of changes are corrections of the wrong access types in ALSA ctl enum items. They are mostly harmless on 32bit architectures, but actually buggy on 64bit. So we addressed all these now in a shot. The rest are various small ASoC driver fixes. Among them, only two changes have been done to ASoC core, and both of them are trivial. The rest are all device-specific. So overall, they should be safe to apply" * tag 'sound-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (33 commits) ASoC: wm_adsp: Fix enum ctl accesses in a wrong type ASoC: wm9081: Fix enum ctl accesses in a wrong type ASoC: wm8996: Fix enum ctl accesses in a wrong type ASoC: wm8994: Fix enum ctl accesses in a wrong type ASoC: wm8985: Fix enum ctl accesses in a wrong type ASoC: wm8983: Fix enum ctl accesses in a wrong type ASoC: wm8958: Fix enum ctl accesses in a wrong type ASoC: wm8904: Fix enum ctl accesses in a wrong type ASoC: wm8753: Fix enum ctl accesses in a wrong type ASoC: wl1273: Fix enum ctl accesses in a wrong type ASoC: tlv320dac33: Fix enum ctl accesses in a wrong type ASoC: max98095: Fix enum ctl accesses in a wrong type ASoC: max98088: Fix enum ctl accesses in a wrong type ASoC: ab8500: Fix enum ctl accesses in a wrong type ASoC: da732x: Fix enum ctl accesses in a wrong type ASoC: cs42l51: Fix enum ctl accesses in a wrong type ASoC: intel: mfld: Fix enum ctl accesses in a wrong type ASoC: omap: rx51: Fix enum ctl accesses in a wrong type ASoC: omap: n810: Fix enum ctl accesses in a wrong type ASoC: pxa: tosa: Fix enum ctl accesses in a wrong type ...

This reverts commit dbb17a21. It turns out that commit can cause problems for systems with multiple GPUs, and causes X to hang on at least a HP Pavilion dv7 with hybrid graphics. This got noticed originally in 4.4.4, where this patch had already gotten back-ported, but 4.5-rc7 was verified to have the same problem. Alexander Deucher says: "It looks like you have a muxed system so I suspect what's happening is that one of the display is being reported as connected for both the IGP and the dGPU and then the desktop environment gets confused or there some sort problem in the detect functions since the mux is not switched to the dGPU. I don't see an easy fix unless Dave has any ideas. I'd say just revert for now" Reported-by:

IPv4 interprets a negative return value from a protocol handler as a request to redispatch to a new protocol. In contrast, IPv6 interprets a negative value as an error, and interprets a positive value as a request for redispatch. UDP for IPv6 was unaware of this difference. Change __udp6_lib_rcv() to return a positive value for redispatch. Note that the socket's encap_rcv hook still needs to return a negative value to request dispatch, and in the case of IPv6 packets, adjust IP6CB(skb)->nhoff to identify the byte containing the next protocol.

vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations, uses pskb_may_pull to linearize the header portion of an skb. That operation eventually uses local_bh_disable/enable to ensure that it doesn't race with the drivers bottom half handler. Unfortunately, vmxnet3 preforms this parse_and_copy operation with a spinlock held and interrupts disabled. This causes us to run afoul of the WARN_ON_ONCE(irqs_disabled()) warning in local_bh_enable, resulting in this: WARNING: at kernel/softirq.c:159 local_bh_enable+0x59/0x90() (Not tainted) Hardware name: VMware Virtual Platform Modules linked in: ipv6 ppdev parport_pc parport microcode e1000 vmware_balloon vmxnet3 i2c_piix4 sg ext4 jbd2 mbcache sd_mod crc_t10dif sr_mod cdrom mptspi mptscsih mptbase scsi_transport_spi pata_acpi ata_generic ata_piix vmwgfx ttm drm_kms_helper drm i2c_core dm_mirror dm_region_hash dm_log dm_mod [last unloaded: mperf] Pid: 6229, comm: sshd Not tainted 2.6.32-616.el6.i686 #1 Call Trace: [<c04624d9>] ? warn_slowpath_common+0x89/0xe0 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c046254b>] ? warn_slowpath_null+0x1b/0x20 [<c0469e99>] ? local_bh_enable+0x59/0x90 [<c07bb936>] ? skb_copy_bits+0x126/0x210 [<f8d1d9fe>] ? ext4_ext_find_extent+0x24e/0x2d0 [ext4] [<c07bc49e>] ? __pskb_pull_tail+0x6e/0x2b0 [<f95a6164>] ? vmxnet3_xmit_frame+0xba4/0xef0 [vmxnet3] [<c05d15a6>] ? selinux_ip_postroute+0x56/0x320 [<c0615988>] ? cfq_add_rq_rb+0x98/0x110 [<c0852df8>] ? packet_rcv+0x48/0x350 [<c07c5839>] ? dev_queue_xmit_nit+0xc9/0x140 ...

This is necessary even if the data interface is already in altsetting 0, which it will be when the device is probed for the first time.

The descriptor queues for sending (SDQs) and receiving (RDQs) packets are managed by two counters - producer and consumer - which are both 16-bit in size. A queue is considered full when the difference between the two equals the queue's maximum number of descriptors. However, if the producer counter overflows, then it's possible for the full queue check to fail, as it doesn't take the overflow into account. In such a case, descriptors already passed to the device - but for which a completion has yet to be posted - will be overwritten, thereby causing undefined behavior. The above can be achieved under heavy load (~30 netperf instances). Fix that by casting the subtraction result to u16, preventing it from being treated as a signed integer.

Since we only support one VLAN filtering bridge we need to associate a reference count with it, so that when the last port netdev leaves it, we would know that a different bridge can be offloaded to hardware. When a LAG device is memeber in a bridge and port netdevs are leaving the LAG, we should always decrement the bridge's reference count, as it's incremented for any port in the LAG.

Merge tag 'asoc-fix-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.5 This is far too big a set of fixes for this late in the release cycle but the overwhelming bulk is essentially the same simple fix from Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace interface where drivers were accessing things using the wrong element in a union which worked OK on 32 bit platforms as the correct element happened to be aligned the same way but with 64 bit platforms ABIs are different and the two members of the union are laid out in different places. They aren't all tagged to stable since some of these chips have vanishingly little chance of being used in 64 bit systems. The other changes are: - A fix for Qualcomm devices to work on big endian systems. The original change is actually correct but triggered a bug in regmap which is too invasive to fix for this cycle and can be worked around by just letting regmap pick the default. - A fix for the Samsung I2S driver locking which wasn't using IRQ safe spinlocks when it needed to. - A fix for the new Intel Sky Lake driver forgetting that C pointer arithmetic takes the type of the pointer into consideration. - A revert of a change to the FSL SSI driver that broke some systems. - A fix for the cleanup path of the wm9713 driver. - A fix for some incorrect register definitions in the ADAU17x1 driver that caused misclocking in some configurations. - A fix for the tracepoints for jack detection to avoid using an internal field of the core jack structure which is no longer present in all configurations. - A fix for another of the new Intel drivers which tried to write to a string literal.

commit 4d5cfcba ('tipc: fix connection abort during subscription cancel'), removes the check for a valid subscription before calling tipc_nametbl_subscribe(). This will lead to a nullptr exception when we process a subscription cancel request. For a cancel request, a null subscription is passed to tipc_nametbl_subscribe() resulting in exception. In this commit, we call tipc_nametbl_subscribe() only for a valid subscription. Fixes: 4d5cfcba ('tipc: fix connection abort during subscription cancel') Reported-by:

Before calling the destroy() or target() callbacks, the family parameter field has to be initialized. Otherwise at least the LOG target will refuse to work and upon removal oops the kernel. Cc: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by:

Pull ARM SoC fix from Olof Johansson: "Tiny fixes branch this week, in fact only one patch. Turns out the USB support for a Renesas board was developed on a pre-release board that ended up being changed before shipping. To avoid breakage on those boards, and avoid confusion, it's a reasonable idea to patch now instead of later. There are no known users of the pre-release variant any more" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: porter: remove enable prop from HS-USB device node
