[ Upstream commit dbc2b5e9 ] Commit 0ca50d12 ("sctp: fix src address selection if using secondary addresses") has fixed a src address selection issue when using secondary addresses for ipv4. Now sctp ipv6 also has the similar issue. When using a secondary address, sctp_v6_get_dst tries to choose the saddr which has the most same bits with the daddr by sctp_v6_addr_match_len. It may make some cases not work as expected. hostA: [1] fd21:356b:459a:cf10::11 (eth1) [2] fd21:356b:459a:cf20::11 (eth2) hostB: [a] fd21:356b:459a:cf30::2 (eth1) [b] fd21:356b:459a:cf40::2 (eth2) route from hostA to hostB: fd21:356b:459a:cf30::/64 dev eth1 metric 1024 mtu 1500 The expected path should be: fd21:356b:459a:cf10::11 <-> fd21:356b:459a:cf30::2 But addr[2] matches addr[a] more bits than addr[1] does, according to sctp_v6_addr_match_len. It causes the path to be: fd21:356b:459a:cf20::11 <-> fd21:356b:459a:cf30::2 This patch is to fix it with the same way as Marcelo's fix for sctp ipv4. As no ip_dev_find for ipv6, this patch is to use ipv6_chk_addr to check if the saddr is in a dev instead. Note that for backwards compatibility, it will still do the addr_match_len check here when no optimal is found. Reported-by:

[ Upstream commit 844cf763 ] The macro tipc_wait_for_cond() is embedding the macro sk_wait_event() to fulfil its task. The latter, in turn, is evaluating the stated condition outside the socket lock context. This is problematic if the condition is accessing non-trivial data structures which may be altered by incoming interrupts, as is the case with the cong_links() linked list, used by socket to keep track of the current set of congested links. We sometimes see crashes when this list is accessed by a condition function at the same time as a SOCK_WAKEUP interrupt is removing an element from the list. We fix this by expanding selected parts of sk_wait_event() into the outer macro, while ensuring that all evaluations of a given condition are performed under socket lock protection.

[ Upstream commit b451e5d2 ] This patch fixes a bug in splitting an SKB during SACK processing. Specifically if an skb contains multiple packets and is only partially sacked in the higher sequences, tcp_match_sack_to_skb() splits the skb and marks the second fragment as SACKed. The current code further attempts rounding up the first fragment to MSS boundaries. But it misses a boundary condition when the rounded-up fragment size (pkt_len) is exactly skb size. Spliting such an skb is pointless and causses a kernel warning and aborts the SACK processing. This patch universally checks such over-split before calling tcp_fragment to prevent these unnecessary warnings. Fixes: adb92db8 ("tcp: Make SACK code to split only at mss boundaries") Signed-off-by:

[ Upstream commit f6ba8d33 ] I should have known that lowering skb->truesize was dangerous :/ In case packets are not leaving the host via a standard Ethernet device, but looped back to local sockets, bad things can happen, as reported by Michael Madsen ( https://bugzilla.kernel.org/show_bug.cgi?id=195713 ) So instead of tweaking skb->truesize, lets change skb->destructor and keep a reference on the owner socket via its sk_refcnt.

[ Upstream commit d8b54110 ] Shubham was recently asking on netdev why in arm64 JIT we don't multiply the index for accessing the tail call map by 8. That led me into testing out arm64 JIT wrt tail calls and it turned out I got a NULL pointer dereference on the tail call. The buggy access is at: prog = array->ptrs[index]; if (prog == NULL) goto out; [...] 00000060: d2800e0a mov x10, #0x70 // #112 00000064: f86a682a ldr x10, [x1,x10] 00000068: f862694b ldr x11, [x10,x2] 0000006c: b40000ab cbz x11, 0x00000080 [...] The code triggering the crash is f862694b. x1 at the time contains the address of the bpf array, x10 offsetof(struct bpf_array, ptrs). Meaning, above we load the pointer to the program at map slot 0 into x10. x10 can then be NULL if the slot is not occupied, which we later on try to access with a user given offset in x2 that is the map index. Fix this by emitting the following instead: [...] 00000060: d2800e0a mov x10, #0x70 // #112 00000064: 8b0a002a add x10, x1, x10 00000068: d37df04b lsl x11, x2, #3 0000006c: f86b694b ldr x11, [x10,x11] 00000070: b40000ab cbz x11, 0x00000084 [...] This basically adds the offset to ptrs to the base address of the bpf array we got and we later on access the map with an index * 8 offset relative to that. The tail call map itself is basically one large area with meta data at the head followed by the array of prog pointers. This makes tail calls working again, tested on Cavium ThunderX ARMv8.

Julian Wiedmann authored
[ Upstream commit 2d2ebb3e ] commit b4d72c08 ("qeth: bridgeport support - basic control") broke the support for OSM and OSN devices as follows: As OSM and OSN are L2 only, qeth_core_probe_device() does an early setup by loading the l2 discipline and calling qeth_l2_probe_device(). In this context, adding the l2-specific bridgeport sysfs attributes via qeth_l2_create_device_attributes() hits a BUG_ON in fs/sysfs/group.c, since the basic sysfs infrastructure for the device hasn't been established yet. Note that OSN actually has its own unique sysfs attributes (qeth_osn_devtype), so the additional attributes shouldn't be created at all. For OSM, add a new qeth_l2_devtype that contains all the common and l2-specific sysfs attributes. When qeth_core_probe_device() does early setup for OSM or OSN, assign the corresponding devtype so that the ccwgroup probe code creates the full set of sysfs attributes. This allows us to skip qeth_l2_create_device_attributes() in case of an early setup. Any device that can't do early setup will initially have only the generic sysfs attributes, and when it's probed later qeth_l2_probe_device() adds the l2-specific attributes. If an early-setup device is removed (by calling ccwgroup_ungroup()), device_unregister() will - using the devtype - delete the l2-specific attributes before qeth_l2_remove_device() is called. So make sure to not remove them twice. What complicates the issue is that qeth_l2_probe_device() and qeth_l2_remove_device() is also called on a device when its layer2 attribute changes (ie. its layer mode is switched). For early-setup devices this wouldn't work properly - we wouldn't remove the l2-specific attributes when switching to L3. But switching the layer mode doesn't actually make any sense; we already decided that the device can only operate in L2! So just refuse to switch the layer mode on such devices. Note that OSN doesn't have a layer2 attribute, so we only need to special-case OSM. Based on an initial patch by Ursula Braun.

[ Upstream commit 1a4a5bf5 ] The current codes only deal with the case that the skb is dropped, it may meet one use-after-free issue when NF_HOOK returns 0 that means the skb is stolen by one netfilter rule or hook. When one netfilter rule or hook stoles the skb and return NF_STOLEN, it means the skb is taken by the rule, and other modules should not touch this skb ever. Maybe the skb is queued or freed directly by the rule. Now uses the nf_hook instead of NF_HOOK to get the result of netfilter, and check the return value of nf_hook. Only when its value equals 1, it means the skb could go ahead. Or reset the skb as NULL. BTW, because vrf_rcv_finish is empty function, so needn't invoke it even though nf_hook returns 1. But we need to modify vrf_rcv_finish to deal with the NF_STOLEN case. There are two cases when skb is stolen. 1. The skb is stolen and freed directly. There is nothing we need to do, and vrf_rcv_finish isn't invoked. 2. The skb is queued and reinjected again. The vrf_rcv_finish would be invoked as okfn, so need to free the skb in it. Signed-off-by:

commit b299cde2 upstream. /dev/mem currently allows mmap() mappings that wrap around the end of the physical address space, which should probably be illegal. It circumvents the existing STRICT_DEVMEM permission check because the loop immediately terminates (as the start address is already higher than the end address). On the x86_64 architecture it will then cause a panic (from the BUG(start >= end) in arch/x86/mm/pat.c:reserve_memtype()). This patch adds an explicit check to make sure offset + size will not wrap around in the physical address type. Signed-off-by:

This caused mtd->name to be changed as well. This breaks partition creation via mtdparts passed by u-boot as it uses "omap2-nand.0" for the mtd-id. Fix this by explicitly setting the mtd->name to "omap2-nand.<CS number>" if it isn't already set by nand_set_flash_node(). CS number is the NAND controller instance ID.

commit ea00353f upstream. Laurent Pinchart reported that the Renesas R-Car H2 Lager board (r8a7790) crashes during suspend tests. Geert Uytterhoeven managed to reproduce the issue on an M2-W Koelsch board (r8a7791): It occurs when the PME scan runs, once per second. During PME scan, the PCI host bridge (rcar-pci) registers are accessed while its module clock has already been disabled, leading to the crash. One reproducer is to configure s2ram to use "s2idle" instead of "deep" suspend: # echo 0 > /sys/module/printk/parameters/console_suspend # echo s2idle > /sys/power/mem_sleep # echo mem > /sys/power/state Another reproducer is to write either "platform" or "processors" to /sys/power/pm_test. It does not (or is less likely) to happen during full system suspend ("core" or "none") because system suspend also disables timers, and thus the workqueue handling PME scans no longer runs. Geert believes the issue may still happen in the small window between disabling module clocks and disabling timers: # echo 0 > /sys/module/printk/parameters/console_suspend # echo platform > /sys/power/pm_test # Or "processors" # echo mem > /sys/power/state (Make sure CONFIG_PCI_RCAR_GEN2 and CONFIG_USB_OHCI_HCD_PCI are enabled.) Rafael Wysocki agrees that PME scans should be suspended before the host bridge registers become inaccessible. To that end, queue the task on a workqueue that gets frozen before devices suspend. Rafael notes however that as a result, some wakeup events may be missed if they are delivered via PME from a device without working IRQ (which hence must be polled) and occur after the workqueue has been frozen. If that turns out to be an issue in practice, it may be possible to solve it by calling pci_pme_list_scan() once directly from one of the host bridge's pm_ops callbacks.

commit 6bccc7f4 upstream. In the PCI_MMAP_PROCFS case when the address being passed by the user is a 'user visible' resource address based on the bus window, and not the actual contents of the resource, that's what we need to be checking it against. Signed-off-by:

commit cd183740 upstream. Currently SoCs pass2.x do not emulate EA headers for ACPI boot method at all. However, for pass2.x some devices (like EDAC) advertise incorrect base addresses in their BARs which results in driver probe failure during resource request. Since all problematic blocks are on 2nd NUMA node under domain 10 add necessary quirk entry to obtain BAR addresses correction using EA header emulation.

commit 05d7839a upstream. If thermal bank with 4 sensors, thermal driver should read TEMP_MSR3. However, currently thermal driver would not read TEMP_MSR3 since mt8173 thermal driver only use 3 sensors on each thermal bank at the same time, so this patch would not effect temperature. Only if mt mt8173 thermal driver use 4 sensors on any thermal bank, would read third sensor two times, and lose fourth sensor of vale.
