commit 373c4557 upstream. This matters at least for the mincore syscall, which will otherwise copy uninitialized memory from the page allocator to userspace. It is probably also a correctness error for /proc/$pid/pagemap, but I haven't tested that. Removing the `walk->hugetlb_entry` condition in walk_hugetlb_range() has no effect because the caller already checks for that. This only reports holes in hugetlb ranges to callers who have specified a hugetlb_entry callback. This issue was found using an AFL-based fuzzer. v2: - don't crash on ->pte_hole==NULL (Andrew Morton) - add Cc stable (Andrew Morton) Changed for 4.4/4.9 stable backport: - fix up conflict in the huge_pte_offset() call Fixes: 1e25a271 ("mincore: apply page table walker on do_mincore()") Signed-off-by:

commit e492080e upstream. online_page_ext() and page_ext_init() allocate page_ext for each section, but they do not allocate if the first PFN is !pfn_present(pfn) or !pfn_valid(pfn). Then section->page_ext remains as NULL. lookup_page_ext checks NULL only if CONFIG_DEBUG_VM is enabled. For a valid PFN, __set_page_owner will try to get page_ext through lookup_page_ext. Without CONFIG_DEBUG_VM lookup_page_ext will misuse NULL pointer as value 0. This incurrs invalid address access. This is the panic example when PFN 0x100000 is not valid but PFN 0x13FC00 is being used for page_ext. section->page_ext is NULL, get_entry returned invalid page_ext address as 0x1DFA000 for a PFN 0x13FC00. To avoid this panic, CONFIG_DEBUG_VM should be removed so that page_ext will be checked at all times.

commit f86e4271 upstream. Per the discussion with Joonsoo Kim [1], we need check the return value of lookup_page_ext() for all call sites since it might return NULL in some cases, although it is unlikely, i.e. memory hotplug. Tested with ltp with "page_owner=0".

commit d337b66a upstream. When an application called fsync on a file in Coda a small request with just the file identifier was allocated, but the declared length was set to the size of union of all possible upcall requests. This bug has been around for a very long time and is now caught by the extra checking in usercopy that was introduced in Linux-4.8. The exposure happens when the Coda cache manager process reads the fsync upcall request at which point it is killed. As a result there is nobody servicing any further upcalls, trapping any processes that try to access the mounted Coda filesystem. Signed-off-by:

commit d135e575 upstream. In reset_deferred_meminit() we determine number of pages that must not be deferred. We initialize pages for at least 2G of memory, but also pages for reserved memory in this node. The reserved memory is determined in this function: memblock_reserved_memory_within(), which operates over physical addresses, and returns size in bytes. However, reset_deferred_meminit() assumes that that this function operates with pfns, and returns page count. The result is that in the best case machine boots slower than expected due to initializing more pages than needed in single thread, and in the worst case panics because fewer than needed pages are initialized early.

This patch is a fix specific to the 3.19 - 4.4 kernels. The 4.5 kernel inadvertently fixed this bug differently (db3cbfff), but is not a stable candidate due it being a complicated re-write of the entire feature. This patch fixes a potential timing bug with nvme's asynchronous queue deletion, which causes an allocated request to be accidentally released due to the ordering of the shared completion context among the sq/cq pair. The completion context saves the request that issued the queue deletion. If the submission side deletion happens to reset the active request, the completion side will release the wrong request tag back into the pool of available tags. This means the driver will create multiple commands with the same tag, corrupting the queue context. The error is observable in the kernel logs like: "nvme XX:YY:ZZ completed id XX twice on qid:0" In this particular case, this message occurs because the queue is corrupted. The following timing sequence demonstrates the error: CPU A CPU B ----------------------- ----------------------------- nvme_irq nvme_process_cq async_completion queue_kthread_work -----------> nvme_del_sq_work_handler nvme_delete_cq adapter_async_del_queue nvme_submit_admin_async_cmd cmdinfo->req = req; blk_mq_free_request(cmdinfo->req); <-- wrong request!!! This patch fixes the bug by releasing the request in the completion side prior to waking the submission thread, such that that thread can't muck with the shared completion context.

commit c5cea06b upstream. If the kernel is set to show unhandled signals, and a user task does not handle a SIGILL as a result of an instruction abort, we will attempt to log the offending instruction with dump_instr before killing the task. We use dump_instr to log the encoding of the offending userspace instruction. However, dump_instr is also used to dump instructions from kernel space, and internally always switches to KERNEL_DS before dumping the instruction with get_user. When both PAN and UAO are in use, reading a user instruction via get_user while in KERNEL_DS will result in a permission fault, which leads to an Oops. As we have regs corresponding to the context of the original instruction abort, we can inspect this and only flip to KERNEL_DS if the original abort was taken from the kernel, avoiding this issue. At the same time, remove the redundant (and incorrect) comments regarding the order dump_mem and dump_instr are called in.

commit 020aae3e upstream. Commit b65a9cfc ("Untangling ima mess, part 2: deal with counters") moved the call of ima_file_check() from may_open() to do_filp_open() at a point where the file descriptor is already opened. This breaks the assumption made by IMA that file descriptors being closed belong to files whose access was granted by ima_file_check(). The consequence is that security.ima and security.evm are updated with good values, regardless of the current appraisal status. For example, if a file does not have security.ima, IMA will create it after opening the file for writing, even if access is denied. Access to the file will be allowed afterwards. Avoid this issue by checking the appraisal status before updating security.ima. Signed-off-by:

[ Upstream commit 7c8a61d9 ] Alexandar Potapenko while testing the kernel with KMSAN and syzkaller discovered that in some configurations sctp would leak 4 bytes of kernel stack. Working with his reproducer I discovered that those 4 bytes that are leaked is the scope id of an ipv6 address returned by recvmsg. With a little code inspection and a shrewd guess I discovered that sctp_inet6_skb_msgname only initializes the scope_id field for link local ipv6 addresses to the interface index the link local address pertains to instead of initializing the scope_id field for all ipv6 addresses. That is almost reasonable as scope_id's are meaniningful only for link local addresses. Set the scope_id in all other cases to 0 which is not a valid interface index to make it clear there is nothing useful in the scope_id field. There should be no danger of breaking userspace as the stack leak guaranteed that previously meaningless random data was being returned. Fixes: 372f525b ("SCTP: Resync with LKSCTP tree.")

[ Upstream commit df80cd9b ] Now when peeling off an association to the sock in another netns, all transports in this assoc are not to be rehashed and keep use the old key in hashtable. As a transport uses sk->net as the hash key to insert into hashtable, it would miss removing these transports from hashtable due to the new netns when closing the sock and all transports are being freeed, then later an use-after-free issue could be caused when looking up an asoc and dereferencing those transports. This is a very old issue since very beginning, ChunYu found it with syzkaller fuzz testing with this series: socket$inet6_sctp() bind$inet6() sendto$inet6() unshare(0x40000000) getsockopt$inet_sctp6_SCTP_GET_ASSOC_ID_LIST() getsockopt$inet_sctp6_SCTP_SOCKOPT_PEELOFF() This patch is to block this call when peeling one assoc off from one netns to another one, so that the netns of all transport would not go out-sync with the key in hashtable. Note that this patch didn't fix it by rehashing transports, as it's difficult to handle the situation when the tuple is already in use in the new netns. Besides, no one would like to peel off one assoc to another netns, considering ipaddrs, ifaces, etc. are usually different. Reported-by:

[ Upstream commit 0642840b ] The way people generally use netlink_dump is that they fill in the skb as much as possible, breaking when nla_put returns an error. Then, they get called again and start filling out the next skb, and again, and so forth. The mechanism at work here is the ability for the iterative dumping function to detect when the skb is filled up and not fill it past the brim, waiting for a fresh skb for the rest of the data. However, if the attributes are small and nicely packed, it is possible that a dump callback function successfully fills in attributes until the skb is of size 4080 (libmnl's default page-sized receive buffer size). The dump function completes, satisfied, and then, if it happens to be that this is actually the last skb, and no further ones are to be sent, then netlink_dump will add on the NLMSG_DONE part: nlh = nlmsg_put_answer(skb, cb, NLMSG_DONE, sizeof(len), NLM_F_MULTI); It is very important that netlink_dump does this, of course. However, in this example, that call to nlmsg_put_answer will fail, because the previous filling by the dump function did not leave it enough room. And how could it possibly have done so? All of the nla_put variety of functions simply check to see if the skb has enough tailroom, independent of the context it is in. In order to keep the important assumptions of all netlink dump users, it is therefore important to give them an skb that has this end part of the tail already reserved, so that the call to nlmsg_put_answer does not fail. Otherwise, library authors are forced to find some bizarre sized receive buffer that has a large modulo relative to the common sizes of messages received, which is ugly and buggy. This patch thus saves the NLMSG_DONE for an additional message, for the case that things are dangerously close to the brim. This requires keeping track of the errno from ->dump() across calls.

[ Upstream commit 052d41c0 ] After refcnt reaches zero, vlan_vid_del() could free dev->vlan_info via RCU: RCU_INIT_POINTER(dev->vlan_info, NULL); call_rcu(&vlan_info->rcu, vlan_info_rcu_free); However, the pointer 'grp' still points to that memory since it is set before vlan_vid_del(): vlan_info = rtnl_dereference(dev->vlan_info); if (!vlan_info) goto out; grp = &vlan_info->grp; Depends on when that RCU callback is scheduled, we could trigger a use-after-free in vlan_group_for_each_dev() right following this vlan_vid_del(). Fix it by moving vlan_vid_del() before setting grp. This is also symmetric to the vlan_vid_add() we call in vlan_device_event(). Reported-by:

[ Upstream commit b5f86218 ] After commit 07f4c900 ("tcp/dccp: try to not exhaust ip_local_port_range in connect()"), we will try to use even ports for connect(). Then if an application (seen clearly with iperf) opens multiple streams to the same destination IP and port, each stream will be given an even source port. So the bonding driver's simple xmit_hash_policy based on layer3+4 addressing will always hash all these streams to the same interface. And the total throughput will limited to a single slave. Change the tcp code will impact the whole tcp behavior, only for bonding usage. Paolo Abeni suggested fix this by changing the bonding code only, which should be more reasonable, and less impact. Fix this by discarding the lowest hash bit because it contains little entropy. After the fix we can re-balance between slaves. Signed-off-by:

commit 2ef47001 upstream. The USB kerneldoc says that the actual_length field "is read in non-iso completion functions", but the usbfs driver uses it for all URB types in processcompl(). Since not all of the host controller drivers set actual_length for isochronous URBs, programs using usbfs with some host controllers don't work properly. For example, Minas reports that a USB camera controlled by libusb doesn't work properly with a dwc2 controller. It doesn't seem worthwhile to change the HCDs and the documentation, since the in-kernel USB class drivers evidently don't rely on actual_length for isochronous transfers. The easiest solution is for usbfs to calculate the actual_length value for itself, by adding up the lengths of the individual packets in an isochronous transfer. Signed-off-by:

[ Upstream commit 9799270a ] Code in arch/mips/netlogic/common/irq.c which handles the XLP PIC fails to build in XLR configurations due to cpu_is_xlp9xx not being defined, leading to the following build failure: arch/mips/netlogic/common/irq.c: In function ‘xlp_of_pic_init’: arch/mips/netlogic/common/irq.c:298:2: error: implicit declaration of function ‘cpu_is_xlp9xx’ [-Werror=implicit-function-declaration] if (cpu_is_xlp9xx()) { ^ Although the code was conditional upon CONFIG_OF which is indirectly selected by CONFIG_NLM_XLP_BOARD but not CONFIG_NLM_XLR_BOARD, the failing XLR with CONFIG_OF configuration can be configured manually or by randconfig. Fix the build failure by making the affected XLP PIC code conditional upon CONFIG_CPU_XLP which is used to guard the inclusion of asm/netlogic/xlp-hal/xlp.h that provides the required cpu_is_xlp9xx function.

[ Upstream commit e89ef66d ] Memories managed through boot_mem_map are generally expected to define non-crossing areas. However, if part of a larger memory block is marked as reserved, it would still be added to bootmem allocator as an available block and could end up being overwritten by the allocator. Prevent this by explicitly marking the memory as reserved it if exists in the range used by bootmem allocator. Signed-off-by:

[ Upstream commit 08889582 ] When building a kernel targeting a microMIPS ISA, recent GNU linkers will fail the link if they cannot determine that the target of a branch or jump is microMIPS code, with errors such as the following: mips-img-linux-gnu-ld: arch/mips/built-in.o: .text+0x542c: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. mips-img-linux-gnu-ld: final link failed: Bad value or: ./arch/mips/include/asm/uaccess.h:1017: warning: JALX to a non-word-aligned address Placing anything other than an instruction at the start of a function written in assembly appears to trigger such errors. In order to prepare for allowing us to follow function prologue macros with an EXPORT_SYMBOL invocation, end the prologue macros (LEAD, NESTED & FEXPORT) with a .insn directive. This ensures that the start of the function is marked as code, which always makes sense for functions & safely prevents us from hitting the link errors described above. Signed-off-by:

[ Upstream commit f7f37e7f ] When an interface is part of a namespace it is possible that ixgbe_close() may be called while __ixgbe_shutdown() is running which ends up in a double free WARN and/or a BUG in free_msi_irqs(). To handle this situation we extend the rtnl_lock() to protect the call to netif_device_detach() and ixgbe_clear_interrupt_scheme() in __ixgbe_shutdown() and check for netif_device_present() to avoid clearing the interrupts second time in ixgbe_close(); Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().

[ Upstream commit 126db13f ] Make sure that we free the IRQs in ixgbe_io_error_detected() when responding to an PCIe AER error and also restore them when the interface recovers from it. Previously it was possible to trigger BUG_ON() check in free_msix_irqs() in the case where we call ixgbe_remove() after a failed recovery from AER error because the interrupts were not freed.
