Fix it by always doing truncate_inode_pages which is already ready for nrpages == 0 && nrexceptional == 0 case and just invalidates inode.

[PATCH 4.9] mm: do not bug_on on incorrect length in __mm_populate()

by Ben Hutchings

From: Michal Hocko <mhocko(a)suse.com> commit bb177a732c4369bb58a1fe1df8f552b6f0f7db5f upstream. syzbot has noticed that a specially crafted library can easily hit VM_BUG_ON in __mm_populate kernel BUG at mm/gup.c:1242! invalid opcode: 0000 [#1] SMP CPU: 2 PID: 9667 Comm: a.out Not tainted 4.18.0-rc3 #644 Hardware name: VMware, Inc.

There is no reason to bug on that though. do_brk_flags already aligns the length properly so the mapping is expanded as it should. All we need is to tell mm_populate about it. Besides that there is absolutely no reason to to bug_on in the first place. The worst thing that could happen is that the last page wouldn't get populated and that is far from putting system into an inconsistent state. Fix the issue by moving the length sanitization code from do_brk_flags up to vm_brk_flags. The only other caller of do_brk_flags is brk syscall entry and it makes sure to provide the proper length so t here is no need for sanitation and so we can use do_brk_flags without it. Also remove the bogus BUG_ONs.

[PATCH v2] ubifs: Handle re-linking of inodes correctly while recovery

by Richard Weinberger

UBIFS's recovery code strictly assumes that a deleted inode will never come back, therefore it removes all data which belongs to that inode as soon it faces an inode with link count 0 in the replay list. Before O_TMPFILE this assumption was perfectly fine. With O_TMPFILE it can lead to data loss upon a power-cut. Consider a journal with entries like: 0: inode X (nlink = 0) /* O_TMPFILE was created */ 1: data for inode X /* Someone writes to the temp file */ 2: inode X (nlink = 0) /* inode was changed, xattr, chmod, … */ 3: inode X (nlink = 1) /* inode was re-linked via linkat() */ Upon replay of entry #2 UBIFS will drop all data that belongs to inode X, this will lead to an empty file after mounting. As solution for this problem, scan the replay list for a re-link entry before dropping data.

[PATCH 1/1] xhci: Prevent bus suspend if a port connect change or polling state is detected

by Mathias Nyman

USB3 roothub might autosuspend before a plugged USB3 device is detected, causing USB3 device enumeration failure. USB3 devices don't show up as connected and enabled until USB3 link trainig completes. On a fast booting platform with a slow USB3 link training the link might reach the connected enabled state just as the bus is suspending. If this device is discovered first time by the xhci_bus_suspend() routine it will be put to U3 suspended state like the other ports which failed to suspend earlier. The hub thread will notice the connect change and resume the bus, moving the port back to U0 This U0 -> U3 -> U0 transition right after being connected seems to be too much for some devices, causing them to first go to SS.Inactive state, and finally end up stuck in a polling state with reset asserted Fix this by failing the bus suspend if a port has a connect change or is in a polling state in xhci_bus_suspend(). Don't do any port changes until all ports are checked, buffer all port changes and only write them in the end if suspend can proceed Cc: stable(a)vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> --- drivers/usb/host/xhci-hub.c | 60 ++++++++++++++++++++++++++++++++++----------- 1 file changed, 46 insertions(+), 14 deletions(-) diff --git a/drivers/usb/host/xhci-hub.c b/drivers/usb/host/xhci-hub.c index da98a11..94aca1b 100644 --- a/drivers/usb/host/xhci-hub.c +++ b/drivers/usb/host/xhci-hub.c @@ -1474,15 +1474,18 @@ int xhci_bus_suspend(struct usb_hcd *hcd) unsigned long flags; struct xhci_hub *rhub; struct xhci_port **ports; + u32 portsc_buf[USB_MAXCHILDREN]; + bool wake_enabled; rhub = xhci_get_rhub(hcd); ports = rhub->ports; max_ports = rhub->num_ports; bus_state = &xhci->bus_state[hcd_index(hcd)]; + wake_enabled = hcd->self.root_hub->do_remote_wakeup; spin_lock_irqsave(&xhci->lock, flags); - if (hcd->self.root_hub->do_remote_wakeup) { + if (wake_enabled) { if (bus_state->resuming_ports || /* USB2 */ bus_state->port_remote_wakeup) { /* USB3 */ spin_unlock_irqrestore(&xhci->lock, flags); @@ -1490,26 +1493,36 @@ int xhci_bus_suspend(struct usb_hcd *hcd) return -EBUSY; } } - - port_index = max_ports; + /* + * Prepare ports for suspend, but don't write anything before all ports + * are checked and we know bus suspend can proceed + */ bus_state->bus_suspended = 0; + port_index = max_ports; while (port_index--) { - /* suspend the port if the port is not suspended */ u32 t1, t2; - int slot_id; t1 = readl(ports[port_index]->addr); t2 = xhci_port_state_to_neutral(t1); + portsc_buf[port_index] = 0; - if ((t1 & PORT_PE) && !(t1 & PORT_PLS_MASK)) { - xhci_dbg(xhci, "port %d not suspended\n", port_index); - slot_id = xhci_find_slot_id_by_port(hcd, xhci, - port_index + 1); - if (slot_id) { + /* Bail out if a USB3 port has a new device in link training */ + if ((t1 & PORT_PLS_MASK) == XDEV_POLLING) { + bus_state->bus_suspended = 0; + spin_unlock_irqrestore(&xhci->lock, flags); + xhci_dbg(xhci, "Bus suspend bailout, port in polling\n"); + return -EBUSY; + } + + /* suspend ports in U0, or bail out for new connect changes */ + if ((t1 & PORT_PE) && (t1 & PORT_PLS_MASK) == XDEV_U0) { + if ((t1 & PORT_CSC) && wake_enabled) { + bus_state->bus_suspended = 0; spin_unlock_irqrestore(&xhci->lock, flags); - xhci_stop_device(xhci, slot_id, 1); - spin_lock_irqsave(&xhci->lock, flags); + xhci_dbg(xhci, "Bus suspend bailout, port connect change\n"); + return -EBUSY; } + xhci_dbg(xhci, "port %d not suspended\n", port_index); t2 &= ~PORT_PLS_MASK; t2 |= PORT_LINK_STROBE | XDEV_U3; set_bit(port_index, &bus_state->bus_suspended); @@ -1518,7 +1531,7 @@ int xhci_bus_suspend(struct usb_hcd *hcd) * including the USB 3.0 roothub, but only if CONFIG_PM * is enabled, so also enable remote wake here. */ - if (hcd->self.root_hub->do_remote_wakeup) { + if (wake_enabled) { if (t1 & PORT_CONNECT) { t2 |= PORT_WKOC_E | PORT_WKDISC_E; t2 &= ~PORT_WKCONN_E; @@ -1538,7 +1551,26 @@ int xhci_bus_suspend(struct usb_hcd *hcd) t1 = xhci_port_state_to_neutral(t1); if (t1 != t2) - writel(t2, ports[port_index]->addr); + portsc_buf[port_index] = t2; + } + + /* write port settings, stopping and suspending ports if needed */ + port_index = max_ports; + while (port_index--) { + if (!portsc_buf[port_index]) + continue; + if (test_bit(port_index, &bus_state->bus_suspended)) { + int slot_id; + + slot_id = xhci_find_slot_id_by_port(hcd, xhci, + port_index + 1); + if (slot_id) { + spin_unlock_irqrestore(&xhci->lock, flags); + xhci_stop_device(xhci, slot_id, 1); + spin_lock_irqsave(&xhci->lock, flags); + } + } + writel(portsc_buf[port_index], ports[port_index]->addr); } hcd->state = HC_STATE_SUSPENDED; bus_state->next_statechange = jiffies + msecs_to_jiffies(10); -- 2.7.4

[PATCH V5 5/8] MIPS: Align kernel load address to 64KB

by Huacai Chen

KEXEC needs the new kernel's load address to be aligned on a page boundary (see sanity_check_segment_list()), but on MIPS the default vmlinuz load address is only explicitly aligned to 16 bytes. Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase the alignment calculated by calc_vmlinuz_load_addr to 64KB.

[PATCH V5 2/8] MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3

by Huacai Chen

For multi-node Loongson-3 (NUMA configuration), r4k_blast_scache() can only flush Node-0's scache. So we add r4k_blast_scache_node() by using (CAC_BASE | (node_id << NODE_ADDRSPACE_SHIFT)) instead of CKSEG0 as the start address.

[PATCH] drm/nouveau: Check rc from drm_dp_mst_topology_mgr_resume()

by Lyude Paul

We need to actually make sure we check this on resume since otherwise we won't know whether or not the topology is still there once we've resumed, which will cause us to still think the topology is connected even after it's been removed if the removal happens mid-suspend.
