2020-03-11gpiolib: acpi: Correct comment for HP x2 10 honor_wakeup quirkHans de Goede
Commit aa23ca3d98f7 ("gpiolib: acpi: Add honor_wakeup module-option + quirk mechanism") added a quirk for some models of the HP x2 10 series. There are 2 issues with the comment describing the quirk: 1) The comment claims the DMI quirk applies to all Cherry Trail based HP x2 10 models. In the mean time I have learned that there are at least 3 models of the HP x2 10 models: Bay Trail SoC + AXP288 PMIC Cherry Trail SoC + AXP288 PMIC Cherry Trail SoC + TI PMIC And this quirk's DMI matches only match the Cherry Trail SoC + TI PMIC SoC, which is good because we want a slightly different quirk for the others. This commit updates the comment to make it clear that the quirk is only for the Cherry Trail SoC + TI PMIC models. 2) The comment says that it is ok to disable wakeup on all ACPI GPIO event handlers, because there is only the one for the embedded-controller events. This is not true, there also is a handler for the special INT0002 device which is related to USB wakeups. We need to also disable wakeups on that one because the device turns of the USB-keyboard built into the dock when closing the lid. The XHCI controller takes a while to notice this, so it only notices it when already suspended, causing a spurious wakeup because of this. So disabling wakeup on all handlers is the right thing to do, but not because there only is the one handler for the EC events. This commit updates the comment to correctly reflect this.

2020-03-11gpiolib: Fix irq_disable() semanticsLinus Walleij
The implementation if .irq_disable() which kicks in between the gpiolib and the driver is not properly mimicking the expected semantics of the irqchip core: the irqchip will call .irq_disable() if that exists, else it will call mask_irq() which first checks if .irq_mask() is defined before calling it. Since we are calling it unconditionally, we get this bug from drivers/pinctrl/qcom/pinctrl-ssbi-gpio.c, as it only defines .irq_mask_ack and not .irq_mask: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = (ptrval) (...) PC is at 0x0 LR is at gpiochip_irq_disable+0x20/0x30 Fix this by only calling .irq_mask() if it exists.

2020-03-11x86/ioremap: Map EFI runtime services data as encrypted for SEVTom Lendacky
The dmidecode program fails to properly decode the SMBIOS data supplied by OVMF/UEFI when running in an SEV guest. The SMBIOS area, under SEV, is encrypted and resides in reserved memory that is marked as EFI runtime services data. As a result, when memremap() is attempted for the SMBIOS data, it can't be mapped as regular RAM (through try_ram_remap()) and, since the address isn't part of the iomem resources list, it isn't mapped encrypted through the fallback ioremap(). Add a new __ioremap_check_other() to deal with memory types like EFI_RUNTIME_SERVICES_DATA which are not covered by the resource ranges. This allows any runtime services data which has been created encrypted, to be mapped encrypted too.

2020-03-11ftrace: Return the first found result in lookup_rec()Artem Savkov
It appears that ip ranges can overlap so. In that case lookup_rec() returns whatever results it got last even if it found nothing in last searched page. This breaks an obscure livepatch late module patching usecase: - load livepatch - load the patched module - unload livepatch - try to load livepatch again To fix this return from lookup_rec() as soon as it found the record containing searched-for ip. This used to be this way prior lookup_rec() introduction.

2020-03-11bpf, sockmap: Remove bucket->lock from sock_{hash|map}_freeJohn Fastabend
The bucket->lock is not needed in the sock_hash_free and sock_map_free calls, in fact it is causing a splat due to being inside rcu block. | BUG: sleeping function called from invalid context at net/core/sock.c:2935 | in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 62, name: kworker/0:1 | 3 locks held by kworker/0:1/62: | #0: ffff88813b019748 ((wq_completion)events){+.+.}, at: process_one_work+0x1d7/0x5e0 | #1: ffffc900000abe50 ((work_completion)(&map->work)){+.+.}, at: process_one_work+0x1d7/0x5e0 | #2: ffff8881381f6df8 (&stab->lock){+...}, at: sock_map_free+0x26/0x180 | CPU: 0 PID: 62 Comm: kworker/0:1 Not tainted 5.5.0-04008-g7b083332376e #454 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS ?-20190727_073836-buildvm-ppc64le-16.ppc.fedoraproject.org-3.fc31 04/01/2014 | Workqueue: events bpf_map_free_deferred | Call Trace: | dump_stack+0x71/0xa0 | ___might_sleep.cold+0xa6/0xb6 | lock_sock_nested+0x28/0x90 | sock_map_free+0x5f/0x180 | bpf_map_free_deferred+0x58/0x80 | process_one_work+0x260/0x5e0 | worker_thread+0x4d/0x3e0 | kthread+0x108/0x140 | ? process_one_work+0x5e0/0x5e0 | ? kthread_park+0x90/0x90 | ret_from_fork+0x3a/0x50 The reason we have stab->lock and bucket->locks in sockmap code is to handle checking EEXIST in update/delete cases. We need to be careful during an update operation that we check for EEXIST and we need to ensure that the psock object is not in some partial state of removal/insertion while we do this. So both map_update_common and sock_map_delete need to guard from being run together potentially deleting an entry we are checking, etc. But by the time we get to the tear-down code in sock_{ma[|hash}_free we have already disconnected the map and we just did synchronize_rcu() in the line above so no updates/deletes should be in flight. Because of this we can drop the bucket locks from the map free'ing code, noting no update/deletes can be in-flight.

2020-03-10s390/qeth: cancel RX reclaim work earlierJulian Wiedmann
When qeth's napi poll code fails to refill an entirely empty RX ring, it kicks off buffer_reclaim_work to try again later. Make sure that this worker is cancelled when setting the qeth device offline. Otherwise a RX refill action can unexpectedly end up running concurrently to bigger re-configurations (eg. resizing the buffer pool), without any locking.

2020-03-10s390/qeth: don't reset default_out_queueJulian Wiedmann
When an OSA device in prio-queue setup is reduced to 1 TX queue due to HW restrictions, we reset its the default_out_queue to 0. In the old code this was needed so that qeth_get_priority_queue() gets the queue selection right. But with proper multiqueue support we already reduced dev->real_num_tx_queues to 1, and so the stack puts all traffic on txq 0 without even calling .ndo_select_queue. Thus we can preserve the user's configuration, and apply it if the OSA device later re-gains support for multiple TX queues.

2020-03-10ipv6/addrconf: call ipv6_mc_up() for non-Ethernet interfaceHangbin Liu
Rafał found an issue that for non-Ethernet interface, if we down and up frequently, the memory will be consumed slowly. The reason is we add allnodes/allrouters addressed in multicast list in ipv6_add_dev(). When link down, we call ipv6_mc_down(), store all multicast addresses via mld_add_delrec(). But when link up, we don't call ipv6_mc_up() for non-Ethernet interface to remove the addresses. This makes idev->mc_tomb getting bigger and bigger. The call stack looks like: addrconf_notify(NETDEV_REGISTER) ipv6_add_dev ipv6_dev_mc_inc(ff01::1) ipv6_dev_mc_inc(ff02::1) ipv6_dev_mc_inc(ff02::2) addrconf_notify(NETDEV_UP) addrconf_dev_config /* Alas, we support only Ethernet autoconfiguration. */ return; addrconf_notify(NETDEV_DOWN) addrconf_ifdown ipv6_mc_down igmp6_group_dropped(ff02::2) mld_add_delrec(ff02::2) igmp6_group_dropped(ff02::1) igmp6_group_dropped(ff01::1) After investigating, I can't found a rule to disable multicast on non-Ethernet interface. In RFC2460, the link could be Ethernet, PPP, ATM, tunnels, etc. In IPv4, it doesn't check the dev type when calls ip_mc_up() in inetdev_event(). Even for IPv6, we don't check the dev type and call ipv6_add_dev(), ipv6_dev_mc_inc() after register device. So I think it's OK to fix this memory consumer by calling ipv6_mc_up() for non-Ethernet interface. v2: Also check IFF_MULTICAST flag to make sure the interface supports multicast Reported-by: Rafał Miłecki <zajec5@gmail.com> Tested-by: Rafał Miłecki <zajec5@gmail.com> Fixes: 74235a25c673 ("[IPV6] addrconf: Fix IPv6 on tuntap tunnels") Fixes: 1666d49e1d41 ("mld: do not remove mld souce list info when set link down") Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.

2020-03-10net: memcg: late association of sock to memcgShakeel Butt
If a TCP socket is allocated in IRQ context or cloned from unassociated (i.e. not associated to a memcg) in IRQ context then it will remain unassociated for its whole life. Almost half of the TCPs created on the system are created in IRQ context, so, memory used by such sockets will not be accounted by the memcg. This issue is more widespread in cgroup v1 where network memory accounting is opt-in but it can happen in cgroup v2 if the source socket for the cloning was created in root memcg. To fix the issue, just do the association of the sockets at the accept() time in the process context and then force charge the memory buffer already used and reserved by the socket.

2020-03-10cgroup: memcg: net: do not associate sock with unrelated cgroupShakeel Butt
We are testing network memory accounting in our setup and noticed inconsistent network memory usage and often unrelated cgroups network usage correlates with testing workload. On further inspection, it seems like mem_cgroup_sk_alloc() and cgroup_sk_alloc() are broken in irq context specially for cgroup v1. mem_cgroup_sk_alloc() and cgroup_sk_alloc() can be called in irq context and kind of assumes that this can only happen from sk_clone_lock() and the source sock object has already associated cgroup. However in cgroup v1, where network memory accounting is opt-in, the source sock can be unassociated with any cgroup and the new cloned sock can get associated with unrelated interrupted cgroup. Cgroup v2 can also suffer if the source sock object was created by process in the root cgroup or if sk_alloc() is called in irq context. The fix is to just do nothing in interrupt. WARNING: Please note that about half of the TCP sockets are allocated from the IRQ context, so, memory used by such sockets will not be accouted by the memcg.

2020-03-10RDMA/mlx5: Fix the number of hwcounters of a dynamic counterMark Zhang
When we read the global counter and there's any dynamic counter allocated, the value of a hwcounter is the sum of the default counter and all dynamic counters. So the number of hwcounters of a dynamically allocated counter must be same as of the default counter, otherwise there will be read violations. This fixes the KASAN slab-out-of-bounds bug: BUG: KASAN: slab-out-of-bounds in rdma_counter_get_hwstat_value+0x36d/0x390 [ib_core] Read of size 8 at addr ffff8884192a5778 by task rdma/10138 CPU: 7 PID: 10138 Comm: rdma Not tainted 5.5.0-for-upstream-dbg-2020-02-06_18-30-19-27 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.1-0-ga5cab58e9a3f-prebuilt.qemu.org 04/01/2014 Call Trace: dump_stack+0xb7/0x10b print_address_description.constprop.4+0x1e2/0x400 ? rdma_counter_get_hwstat_value+0x36d/0x390 [ib_core] __kasan_report+0x15c/0x1e0 ? mlx5_ib_query_q_counters+0x13f/0x270 [mlx5_ib] ? rdma_counter_get_hwstat_value+0x36d/0x390 [ib_core] kasan_report+0xe/0x20 rdma_counter_get_hwstat_value+0x36d/0x390 [ib_core] ? rdma_counter_query_stats+0xd0/0xd0 [ib_core] ? memcpy+0x34/0x50 ? nla_put+0xe2/0x170 nldev_stat_get_doit+0x9c7/0x14f0 [ib_core] ... do_syscall_64+0x95/0x490 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7fcc457fe65a Code: bb 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 8b 05 fa f1 2b 00 45 89 c9 4c 63 d1 48 63 ff 85 c0 75 15 b8 2c 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 76 f3 c3 0f 1f 40 00 41 55 41 54 4d 89 c5 55 RSP: 002b:00007ffc0586f868 EFLAGS: 00000246 ORIG_RAX: 000000000000002c RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007fcc457fe65a RDX: 0000000000000020 RSI: 00000000013db920 RDI: 0000000000000003 RBP: 00007ffc0586fa90 R08: 00007fcc45ac10e0 R09: 000000000000000c R10: 0000000000000000 R11: 0000000000000246 R12: 00000000004089c0 R13: 0000000000000000 R14: 00007ffc0586fab0 R15: 00000000013dc9a0 Allocated by task 9700: save_stack+0x19/0x80 __kasan_kmalloc.constprop.7+0xa0/0xd0 mlx5_ib_counter_alloc_stats+0xd1/0x1d0 [mlx5_ib] rdma_counter_alloc+0x16d/0x3f0 [ib_core] rdma_counter_bind_qpn_alloc+0x216/0x4e0 [ib_core] nldev_stat_set_doit+0x8c2/0xb10 [ib_core] rdma_nl_rcv_msg+0x3d2/0x730 [ib_core] rdma_nl_rcv+0x2a8/0x400 [ib_core] netlink_unicast+0x448/0x620 netlink_sendmsg+0x731/0xd10 sock_sendmsg+0xb1/0xf0 __sys_sendto+0x25d/0x2c0 __x64_sys_sendto+0xdd/0x1b0 do_syscall_64+0x95/0x490 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 18d422ce8ccf ("IB/mlx5: Add counter_alloc_stats() and counter_update_stats() support") Link: https://lore.kernel.org/r/20200305124052.196688-1-leon@kernel.org Signed-off-by: Mark Zhang <markz@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
