commit dca5244 upstream. GCC versions >= 4.9 and < 5.1 have been shown to emit memory references beyond the stack pointer, resulting in memory corruption if an interrupt is taken after the stack pointer has been adjusted but before the reference has been executed. This leads to subtle, infrequent data corruption such as the EXT4 problems reported by Russell King at the link below. Life is too short for buggy compilers, so raise the minimum GCC version required by arm64 to 5.1.

commit ef3a575 upstream. Allow issuing an IOCTL_PRIVCMD_MMAP_RESOURCE ioctl with num = 0 and addr = 0 in order to fetch the size of a specific resource. Add a shortcut to the default map resource path, since fetching the size requires no address to be passed in, and thus no VMA to setup. This is missing from the initial implementation, and causes issues when mapping resources that don't have fixed or known sizes.

commit 51b2ee7 upstream. If you export a subdirectory of a filesystem, a READDIRPLUS on the root of that export will return the filehandle of the parent with the ".." entry. The filehandle is optional, so let's just not return the filehandle for ".." if we're at the root of an export. Note that once the client learns one filehandle outside of the export, they can trivially access the rest of the export using further lookups. However, it is also not very difficult to guess filehandles outside of the export. So exporting a subdirectory of a filesystem should considered equivalent to providing access to the entire filesystem. To avoid confusion, we recommend only exporting entire filesystems.

[ Upstream commit a2bc221 ] For all PCI functions on the netxen_nic adapter, interrupt mode (INTx or MSI) configuration is dependent on what has been configured by the PCI function zero in the shared interrupt register, as these adapters do not support mixed mode interrupts among the functions of a given adapter. Logic for setting MSI/MSI-x interrupt mode in the shared interrupt register based on PCI function id zero check is not appropriate for all family of netxen adapters, as for some of the netxen family adapters PCI function zero is not really meant to be probed/loaded in the host but rather just act as a management function on the device, which caused all the other PCI functions on the adapter to always use legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode. This patch replaces that check with port number so that for all type of adapters driver attempts for MSI/MSI-x interrupt modes.

commit dcfea72 upstream. As part of the continual effort to remove direct usage of skb->next and skb->prev, this patch adds a helper for iterating through the singly-linked variant of skb lists, which are used for lists of GSO packet. The name "skb_list_..." has been chosen to match the existing function, "kfree_skb_list, which also operates on these singly-linked lists, and the "..._walk_safe" part is the same idiom as elsewhere in the kernel. This patch removes the helper from wireguard and puts it into linux/skbuff.h, while making it a bit more robust for general usage. In particular, parenthesis are added around the macro argument usage, and it now accounts for trying to iterate through an already-null skb pointer, which will simply run the iteration zero times. This latter enhancement means it can be used to replace both do { ... } while and while (...) open-coded idioms. This should take care of these three possible usages, which match all current methods of iterations. skb_list_walk_safe(segs, skb, next) { ... } skb_list_walk_safe(skb, skb, next) { ... } skb_list_walk_safe(segs, skb, segs) { ... } Gcc appears to generate efficient code for each of these.

[ Upstream commit b210de4 ] There are cases where GSO segment's length exceeds the egress MTU: - Forwarding of a TCP GRO skb, when DF flag is not set. - Forwarding of an skb that arrived on a virtualisation interface (virtio-net/vhost/tap) with TSO/GSO size set by other network stack. - Local GSO skb transmitted on an NETIF_F_TSO tunnel stacked over an interface with a smaller MTU. - Arriving GRO skb (or GSO skb in a virtualised environment) that is bridged to a NETIF_F_TSO tunnel stacked over an interface with an insufficient MTU. If so: - Consume the SKB and its segments. - Issue an ICMP packet with 'Packet Too Big' message containing the MTU, allowing the source host to reduce its Path MTU appropriately.

[ Upstream commit 826f328 ] DCB uses the same handler function for both RTM_GETDCB and RTM_SETDCB messages. dcb_doit() bounces RTM_SETDCB mesasges if the user does not have the CAP_NET_ADMIN capability. However, the operation to be performed is not decided from the DCB message type, but from the DCB command. Thus DCB_CMD_*_GET commands are used for reading DCB objects, the corresponding SET and DEL commands are used for manipulation. The assumption is that set-like commands will be sent via an RTM_SETDCB message, and get-like ones via RTM_GETDCB. However, this assumption is not enforced. It is therefore possible to manipulate DCB objects without CAP_NET_ADMIN capability by sending the corresponding command in an RTM_GETDCB message. That is a bug. Fix it by validating the type of the request message against the type used for the response.

[ Upstream commit df85bc1 ] In commit 826f328 ("net: dcb: Validate netlink message in DCB handler"), Linux started rejecting RTM_GETDCB netlink messages if they contained a set-like DCB_CMD_ command. The reason was that privileges were only verified for RTM_SETDCB messages, but the value that determined the action to be taken is the command, not the message type. And validation of message type against the DCB command was the obvious missing piece. Unfortunately it turns out that mlnx_qos, a somewhat widely deployed tool for configuration of DCB, accesses the DCB set-like APIs through RTM_GETDCB. Therefore do not bounce the discrepancy between message type and command. Instead, in addition to validating privileges based on the actual message type, validate them also based on the expected message type. This closes the loophole of allowing DCB configuration on non-admin accounts, while maintaining backward compatibility.

[ Upstream commit 3226b15 ] Both virtio net and napi_get_frags() allocate skbs with a very small skb->head While using page fragments instead of a kmalloc backed skb->head might give a small performance improvement in some cases, there is a huge risk of under estimating memory usage. For both GOOD_COPY_LEN and GRO_MAX_HEAD, we can fit at least 32 allocations per page (order-3 page in x86), or even 64 on PowerPC We have been tracking OOM issues on GKE hosts hitting tcp_mem limits but consuming far more memory for TCP buffers than instructed in tcp_mem[2] Even if we force napi_alloc_skb() to only use order-0 pages, the issue would still be there on arches with PAGE_SIZE >= 32768 This patch makes sure that small skb head are kmalloc backed, so that other objects in the slab page can be reused instead of being held as long as skbs are sitting in socket queues. Note that we might in the future use the sk_buff napi cache, instead of going through a more expensive __alloc_skb() Another idea would be to use separate page sizes depending on the allocated length (to never have more than 4 frags per page) I would like to thank Greg Thelen for his precious help on this matter, analysing crash dumps is always a time consuming task.

[ no upstream commit ] Fix a potential kernel address leakage for the prerequisite where there is a BPF program attached to the cgroup/setsockopt hook. The latter can only be attached under root, however, if the attached program returns 1 to then run the related kernel handler, an unprivileged program could probe for kernel addresses that way. The reason this is possible is that we're under set_fs(KERNEL_DS) when running the kernel setsockopt handler. Aside from old cBPF there is also SCTP's struct sctp_getaddrs_old which contains pointers in the uapi struct that further need copy_from_user() inside the handler. In the normal case this would just return -EFAULT, but under a temporary KERNEL_DS setting the memory would be copied and we'd end up at a different error code, that is, -EINVAL, for both cases given subsequent validations fail, which then allows the app to distinguish and make use of this fact for probing the address space. In case of later kernel versions this issue won't work anymore thanks to Christoph Hellwig's work that got rid of the various temporary set_fs() address space overrides altogether. One potential option for 5.4 as the only affected stable kernel with the least complexity would be to remap those affected -EFAULT copy_from_user() error codes with -EINVAL such that they cannot be probed anymore. Risk of breakage should be rather low for this particular error case.

commit dcf4ff7 upstream. xennet_destroy_queues() relies on info->netdev->real_num_tx_queues to delete queues. Since d7dac08 ("net-sysfs: update the queue counts in the unregistration path"), unregister_netdev() indirectly sets real_num_tx_queues to 0. Those two facts together means, that xennet_destroy_queues() called from xennet_remove() cannot do its job, because it's called after unregister_netdev(). This results in kfree-ing queues that are still linked in napi, which ultimately crashes: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [Freescale#1] PREEMPT SMP PTI CPU: 1 PID: 52 Comm: xenwatch Tainted: G W 5.16.10-1.32.fc32.qubes.x86_64+ Freescale#226 RIP: 0010:free_netdev+0xa3/0x1a0 Code: ff 48 89 df e8 2e e9 00 00 48 8b 43 50 48 8b 08 48 8d b8 a0 fe ff ff 48 8d a9 a0 fe ff ff 49 39 c4 75 26 eb 47 e8 ed c1 66 ff <48> 8b 85 60 01 00 00 48 8d 95 60 01 00 00 48 89 ef 48 2d 60 01 00 RSP: 0000:ffffc90000bcfd00 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff88800edad000 RCX: 0000000000000000 RDX: 0000000000000001 RSI: ffffc90000bcfc30 RDI: 00000000ffffffff RBP: fffffffffffffea0 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000001 R12: ffff88800edad050 R13: ffff8880065f8f88 R14: 0000000000000000 R15: ffff8880066c6680 FS: 0000000000000000(0000) GS:ffff8880f3300000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 00000000e998c006 CR4: 00000000003706e0 Call Trace: <TASK> xennet_remove+0x13d/0x300 [xen_netfront] xenbus_dev_remove+0x6d/0xf0 __device_release_driver+0x17a/0x240 device_release_driver+0x24/0x30 bus_remove_device+0xd8/0x140 device_del+0x18b/0x410 ? _raw_spin_unlock+0x16/0x30 ? klist_iter_exit+0x14/0x20 ? xenbus_dev_request_and_reply+0x80/0x80 device_unregister+0x13/0x60 xenbus_dev_changed+0x18e/0x1f0 xenwatch_thread+0xc0/0x1a0 ? do_wait_intr_irq+0xa0/0xa0 kthread+0x16b/0x190 ? set_kthread_struct+0x40/0x40 ret_from_fork+0x22/0x30 </TASK> Fix this by calling xennet_destroy_queues() from xennet_uninit(), when real_num_tx_queues is still available.
