2019-11-18ASoC: tlv320aic31xx: configure output common-mode voltageLucas Stach3-0/+58
The tlv320aic31xx devices allow to adjust the output common-mode voltage for best analog performance. The datasheet states that the common mode voltage should be set to be <= AVDD/2. This changes allows to configure the output common-mode voltage via a DT property. If the property is absent the voltage is automatically chosen as the highest voltage below/equal to AVDD/2.

2019-11-18ALSA: compress: add flac decoder paramsVinod Koul1-0/+10
The current design of sending codec parameters assumes that decoders will have parsers so they can parse the encoded stream for parameters and configure the decoder. But this assumption may not be universally true and we know some DSPs which do not contain the parsers so additional parameters are required to be passed. So add these parameters starting with FLAC decoder. The size of snd_codec_options is still 120 bytes after this change (due to this being a union) Co-developed-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Vinod Koul <vkoul@kernel.org> Link: https://lore.kernel.org/r/20191115102705.649976-2-vkoul@kernel.org Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2019-11-16ipmr: Fix skb headroom in ipmr_get_route().Guillaume Nault1-1/+2
In route.c, inet_rtm_getroute_build_skb() creates an skb with no headroom. This skb is then used by inet_rtm_getroute() which may pass it to rt_fill_info() and, from there, to ipmr_get_route(). The later might try to reuse this skb by cloning it and prepending an IPv4 header. But since the original skb has no headroom, skb_push() triggers skb_under_panic(): skbuff: skb_under_panic: text:00000000ca46ad8a len:80 put:20 head:00000000cd28494e data:000000009366fd6b tail:0x3c end:0xec0 dev:veth0 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:108! invalid opcode: 0000 [#1] SMP KASAN PTI CPU: 6 PID: 587 Comm: ip Not tainted 5.4.0-rc6+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-2.fc30 04/01/2014 RIP: 0010:skb_panic+0xbf/0xd0 Code: 41 a2 ff 8b 4b 70 4c 8b 4d d0 48 c7 c7 20 76 f5 8b 44 8b 45 bc 48 8b 55 c0 48 8b 75 c8 41 54 41 57 41 56 41 55 e8 75 dc 7a ff <0f> 0b 0f 1f 44 00 00 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 RSP: 0018:ffff888059ddf0b0 EFLAGS: 00010286 RAX: 0000000000000086 RBX: ffff888060a315c0 RCX: ffffffff8abe4822 RDX: 0000000000000000 RSI: 0000000000000008 RDI: ffff88806c9a79cc RBP: ffff888059ddf118 R08: ffffed100d9361b1 R09: ffffed100d9361b0 R10: ffff88805c68aee3 R11: ffffed100d9361b1 R12: ffff88805d218000 R13: ffff88805c689fec R14: 000000000000003c R15: 0000000000000ec0 FS: 00007f6af184b700(0000) GS:ffff88806c980000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ffc8204a000 CR3: 0000000057b40006 CR4: 0000000000360ee0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: skb_push+0x7e/0x80 ipmr_get_route+0x459/0x6fa rt_fill_info+0x692/0x9f0 inet_rtm_getroute+0xd26/0xf20 rtnetlink_rcv_msg+0x45d/0x630 netlink_rcv_skb+0x1a5/0x220 rtnetlink_rcv+0x15/0x20 netlink_unicast+0x305/0x3a0 netlink_sendmsg+0x575/0x730 sock_sendmsg+0xb5/0xc0 ___sys_sendmsg+0x497/0x4f0 __sys_sendmsg+0xcb/0x150 __x64_sys_sendmsg+0x48/0x50 do_syscall_64+0xd2/0xac0 entry_SYSCALL_64_after_hwframe+0x49/0xbe Actually the original skb used to have enough headroom, but the reserve_skb() call was lost with the introduction of inet_rtm_getroute_build_skb() by commit 404eb77ea766 ("ipv4: support sport, dport and ip_proto in RTM_GETROUTE"). We could reserve some headroom again in inet_rtm_getroute_build_skb(), but this function shouldn't be responsible for handling the special case of ipmr_get_route(). Let's handle that directly in ipmr_get_route() by calling skb_realloc_headroom() instead of skb_clone().

2019-11-16net/smc: fix fastopen for non-blocking connect()Ursula Braun1-1/+1
FASTOPEN does not work with SMC-sockets. Since SMC allows fallback to TCP native during connection start, the FASTOPEN setsockopts trigger this fallback, if the SMC-socket is still in state SMC_INIT. But if a FASTOPEN setsockopt is called after a non-blocking connect(), this is broken, and fallback does not make sense. This change complements commit cd2063604ea6 ("net/smc: avoid fallback in case of non-blocking connect") and fixes the syzbot reported problem "WARNING in smc_unhash_sk".

Currently WR sizes are updated from rds_ib_sysctl_max_send_wr and rds_ib_sysctl_max_recv_wr when a connection is shut down. As a result, a connection being down while rds_ib_sysctl_max_send_wr or rds_ib_sysctl_max_recv_wr are updated, will not update the sizes when it comes back up.

2019-11-16seg6: fix skb transport_header after decap_and_validate()Andrea Mayer1-0/+6
in the receive path (more precisely in ip6_rcv_core()) the skb->transport_header is set to skb->network_header + sizeof(*hdr). As a consequence, after routing operations, destination input expects to find skb->transport_header correctly set to the next protocol (or extension header) that follows the network protocol. However, decap behaviors (DX*, DT*) remove the outer IPv6 and SRH extension and do not set again the skb->transport_header pointer correctly. For this reason, the patch sets the skb->transport_header to the skb->network_header + sizeof(hdr) in each DX* and DT* behavior.

2019-11-15mm/debug.c: PageAnon() is true for PageKsm() pagesRalph Campbell1-3/+3
PageAnon() and PageKsm() use the low two bits of the page->mapping pointer to indicate the page type. PageAnon() only checks the LSB while PageKsm() checks the least significant 2 bits are equal to 3. Therefore, PageAnon() is true for KSM pages. __dump_page() incorrectly will never print "ksm" because it checks PageAnon() first. Fix this by checking PageKsm() first.

2019-11-15mm/page_io.c: do not free shared swap slotsVinayak Menon1-3/+3
The following race is observed due to which a processes faulting on a swap entry, finds the page neither in swapcache nor swap. This causes zram to give a zero filled page that gets mapped to the process, resulting in a user space crash later. Consider parent and child processes Pa and Pb sharing the same swap slot with swap_count 2. Swap is on zram with SWP_SYNCHRONOUS_IO set. Virtual address 'VA' of Pa and Pb points to the shared swap entry. Pa Pb fault on VA fault on VA do_swap_page do_swap_page lookup_swap_cache fails lookup_swap_cache fails Pb scheduled out swapin_readahead (deletes zram entry) swap_free (makes swap_count 1) Pb scheduled in swap_readpage (swap_count == 1) Takes SWP_SYNCHRONOUS_IO path zram enrty absent zram gives a zero filled page Fix this by making sure that swap slot is freed only when swap count drops down to one.

2019-11-15mm/memory_hotplug: fix try_offline_node()David Hildenbrand3-16/+64
try_offline_node() is pretty much broken right now: - The node span is updated when onlining memory, not when adding it. We ignore memory that was mever onlined. Bad. - We touch possible garbage memmaps. The pfn_to_nid(pfn) can easily trigger a kernel panic. Bad for memory that is offline but also bad for subsection hotadd with ZONE_DEVICE, whereby the memmap of the first PFN of a section might contain garbage. - Sections belonging to mixed nodes are not properly considered. As memory blocks might belong to multiple nodes, we would have to walk all pageblocks (or at least subsections) within present sections. However, we don't have a way to identify whether a memmap that is not online was initialized (relevant for ZONE_DEVICE). This makes things more complicated. Luckily, we can piggy pack on the node span and the nid stored in memory blocks. Currently, the node span is grown when calling move_pfn_range_to_zone() - e.g., when onlining memory, and shrunk when removing memory, before calling try_offline_node(). Sysfs links are created via link_mem_sections(), e.g., during boot or when adding memory. If the node still spans memory or if any memory block belongs to the nid, we don't set the node offline. As memory blocks that span multiple nodes cannot get offlined, the nid stored in memory blocks is reliable enough (for such online memory blocks, the node still spans the memory). Introduce for_each_memory_block() to efficiently walk all memory blocks. Note: We will soon stop shrinking the ZONE_DEVICE zone and the node span when removing ZONE_DEVICE memory to fix similar issues (access of garbage memmaps) - until we have a reliable way to identify whether these memmaps were properly initialized. This implies later, that once a node had ZONE_DEVICE memory, we won't be able to set a node offline - which should be acceptable. Since commit f1dd2cd13c4b ("mm, memory_hotplug: do not associate hotadded memory to zones until online") memory that is added is not assoziated with a zone/node (memmap not initialized). The introducing commit 60a5a19e7419 ("memory-hotplug: remove sysfs file of node") already missed that we could have multiple nodes for a section and that the zone/node span is updated when onlining pages, not when adding them. I tested this by hotplugging two DIMMs to a memory-less and cpu-less NUMA node. The node is properly onlined when adding the DIMMs. When removing the DIMMs, the node is properly offlined.

2019-11-15mm,thp: recheck each page before collapsing file THPSong Liu1-12/+16
In collapse_file(), for !is_shmem case, current check cannot guarantee the locked page is up-to-date. Specifically, xas_unlock_irq() should not be called before lock_page() and get_page(); and it is necessary to recheck PageUptodate() after locking the page. With this bug and CONFIG_READ_ONLY_THP_FOR_FS=y, madvise(HUGE)'ed .text may contain corrupted data. This is because khugepaged mistakenly collapses some not up-to-date sub pages into a huge page, and assumes the huge page is up-to-date. This will NOT corrupt data in the disk, because the page is read-only and never written back. Fix this by properly checking PageUptodate() after locking the page. This check replaces "VM_BUG_ON_PAGE(!PageUptodate(page), page);". Also, move PageDirty() check after locking the page. Current khugepaged should not try to collapse dirty file THP, because it is limited to read-only .text. The only case we hit a dirty page here is when the page hasn't been written since write. Bail out and retry when this happens. syzbot reported bug on previous version of this patch.

2019-11-15mm: hugetlb: switch to css_tryget() in hugetlb_cgroup_charge_cgroup()Roman Gushchin1-1/+1
An exiting task might belong to an offline cgroup. In this case an attempt to grab a cgroup reference from the task can end up with an infinite loop in hugetlb_cgroup_charge_cgroup(), because neither the cgroup will become online, neither the task will be migrated to a live cgroup. Fix this by switching over to css_tryget(). As css_tryget_online() can't guarantee that the cgroup won't go offline, in most cases the check doesn't make sense. In this particular case users of hugetlb_cgroup_charge_cgroup() are not affected by this change.

We're iterating over and over in the do {} while (!css_tryget_online()) loop, but obviously the memcg won't become online and the exiting task won't be migrated to a live memcg. Let's fix it by switching from css_tryget_online() to css_tryget(). As css_tryget_online() cannot guarantee that the memcg won't go offline, the check is usually useless, except some rare cases when for example it determines if something should be presented to a user.

2019-11-15lib/xz: fix XZ_DYNALLOC to avoid useless memory reallocationsLasse Collin1-0/+1
s->dict.allocated was initialized to 0 but never set after a successful allocation, thus the code always thought that the dictionary buffer has to be reallocated.

Recently, I hit the following issue when running upstream. kernel BUG at mm/vmscan.c:1521! invalid opcode: 0000 [#1] SMP KASAN PTI CPU: 0 PID: 23385 Comm: syz-executor.6 Not tainted 5.4.0-rc4+ #1 RIP: 0010:shrink_page_list+0x12b6/0x3530 mm/vmscan.c:1521 Call Trace: reclaim_pages+0x499/0x800 mm/vmscan.c:2188 madvise_cold_or_pageout_pte_range+0x58a/0x710 mm/madvise.c:453 walk_pmd_range mm/pagewalk.c:53 [inline] walk_pud_range mm/pagewalk.c:112 [inline] walk_p4d_range mm/pagewalk.c:139 [inline] walk_pgd_range mm/pagewalk.c:166 [inline] __walk_page_range+0x45a/0xc20 mm/pagewalk.c:261 walk_page_range+0x179/0x310 mm/pagewalk.c:349 madvise_pageout_page_range mm/madvise.c:506 [inline] madvise_pageout+0x1f0/0x330 mm/madvise.c:542 madvise_vma mm/madvise.c:931 [inline] __do_sys_madvise+0x7d2/0x1600 mm/madvise.c:1113 do_syscall_64+0x9f/0x4c0 arch/x86/entry/common.c:290 entry_SYSCALL_64_after_hwframe+0x49/0xbe madvise_pageout() accesses the specified range of the vma and isolates them, then runs shrink_page_list() to reclaim its memory. But it also isolates the unevictable pages to reclaim. Hence, we can catch the cases in shrink_page_list(). The root cause is that we scan the page tables instead of specific LRU list. and so we need to filter out the unevictable lru pages from our end.

2019-11-15mm: mempolicy: fix the wrong return value and potential pages leak of mbindYang Shi1-5/+9
Commit d883544515aa ("mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified") fixed the return value of mbind() for a couple of corner cases. But, it altered the errno for some other cases, for example, mbind() should return -EFAULT when part or all of the memory range specified by nodemask and maxnode points outside your accessible address space, or there was an unmapped hole in the specified memory range specified by addr and len. Fix this by preserving the errno returned by queue_pages_range(). And, the pagelist may be not empty even though queue_pages_range() returns error, put the pages back to LRU since mbind_range() is not called to really apply the policy so those pages should not be migrated, this is also the old behavior before the problematic commit.

Just got one of these for debugging some unrelated issues, and noticed that Lenovo seems to have gone back to using RMI4 over smbus with Synaptics touchpads on some of their new systems, particularly this one. So, let's enable RMI mode for the X1 Extreme 2nd Generation.

Pull block fixes from Jens Axboe: "A few fixes that should make it into this release. This contains: - io_uring: - The timeout command assumes sequence == 0 means that we want one completion, but this kind of overloading is unfortunate as it prevents users from doing a pure time based wait. Since this operation was introduced in this cycle, let's correct it now, while we can. (me) - One-liner to fix an issue with dependent links and fixed buffer reads. The actual IO completed fine, but the link got severed since we stored the wrong expected value. (me) - Add TIMEOUT to list of opcodes that don't need a file. (Pavel) - rsxx missing workqueue destry calls. Old bug. (Chuhong) - Fix blk-iocost active list check (Jiufei) - Fix impossible-to-hit overflow merge condition, that still hit some folks very rarely (Junichi) - Fix bfq hang issue from 5.3. This didn't get marked for stable, but will go into stable post this merge (Paolo)" * tag 'for-linus-20191115' of git://git.kernel.dk/linux-block: rsxx: add missed destroy_workqueue calls in remove iocost: check active_list of all the ancestors in iocg_activate() block, bfq: deschedule empty bfq_queues not referred by any process io_uring: ensure registered buffer import returns the IO length io_uring: Fix getting file for timeout block: check bi_size overflow before merge io_uring: make timeout sequence == 0 mean no sequence
