If zs_create_pool()->create_handle_cache()->kmem_cache_create() or pool->name allocation fails, zs_create_pool()->destroy_handle_cache() will dereference the NULL pool->handle_cachep. Modify destroy_handle_cache() to avoid this. Signed-off-by:

On -rt, the VM_BUG_ON(!irqs_disabled()) triggers inside the memcg swapout path because the spin_lock_irq(&mapping->tree_lock) in the caller doesn't actually disable the hardware interrupts - which is fine, because on -rt the tophalves run in process context and so we are still safe from preemption while updating the statistics. Remove the VM_BUG_ON() but keep the comment of what we rely on. Signed-off-by:

When hot re-add a node, we will reuse the pgdat of it, so does the zone struct, and when add pages to the target zone, it will init the zone first (including the wait_table) if the zone is not initialized. The judgement of zone initialized is based on zone->wait_table: static inline bool zone_is_initialized(struct zone *zone) { return !!zone->wait_table; } so if we do not set the zone->wait_table to *NULL* after free it, the memory hotplug routine will skip the init of new zone when hot re-add the node, and the wait_table still points to the freed memory, then we will access the invalid address when trying to wake up the waiting people after the i/o operation with the page is done, such as mentioned above.

Josh Hunt authored
UDP encapsulation is broken on IPv6. This is because the logic to resubmit the nexthdr is inverted, checking for a ret value > 0 instead of < 0. Also, the resubmit label is in the wrong position since we already get the nexthdr value when performing decapsulation. In addition the skb pull is no longer necessary either. This changes the return value check to look for < 0, using it for the nexthdr on the next iteration, and moves the resubmit label to the proper location. With these changes the v6 code now matches what we do in the v4 ip input code wrt resubmitting when decapsulating. Signed-off-by:

Robert Shearman authored
The memory pointed to by idev->stats.icmpv6msgdev, idev->stats.icmpv6dev and idev->stats.ipv6 can each be used in an RCU read context without taking a reference on idev. For example, through IP6_*_STATS_* calls in ip6_rcv. These memory blocks are freed without waiting for an RCU grace period to elapse. This could lead to the memory being written to after it has been freed. Fix this by using call_rcu to free the memory used for stats, as well as idev after an RCU grace period has elapsed.

br_fdb_update() can be called in process context in the following way: br_fdb_add() -> __br_fdb_add() -> br_fdb_update() (if NTF_USE flag is set) so we need to disable softirqs because there are softirq users of the hash_lock. One easy way to reproduce this is to modify the bridge utility to set NTF_USE, enable stp and then set maxageing to a low value so br_fdb_cleanup() is called frequently and then just add new entries in a loop. This happens because br_fdb_cleanup() is called from timer/softirq context. The spin locks in br_fdb_update were _bh before commit f8ae737d ("[BRIDGE]: forwarding remove unneeded preempt and bh diasables") and at the time that commit was correct because br_fdb_update() couldn't be called from process context, but that changed after commit: 292d1398 ("bridge: add NTF_USE support") Using local_bh_disable/enable around br_fdb_update() allows us to keep using the spin_lock/unlock in br_fdb_update for the fast-path.

Fix stack pointer offset which could potentially corrupt argument registers in the previous frame. The calculated offset reflects the size of all the registers we need to preserve so there is no need for this erroneous subtraction. [ralf@linux-mips.org: Fixed conflict due to only applying this fix part of the entire series as part of 4.1 fixes.] Signed-off-by:

setup_per_cpu_areas() only setup __per_cpu_offset[] for each possible cpu, but loongson_sysconf.nr_cpus can be greater than possible cpus (due to reserved_cpus_mask). So in loongson3_ipi_interrupt(), percpu access will touch the original varible in .data..percpu section which has been freed. Without this patch, cpu-hotplug will cause memery corruption.

Commit 334c86c4 ("MIPS: IRQ: Add stackoverflow detection") added kernel stack overflow detection, however it only enabled it conditional upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so switch it to using that definition instead.
