[ Upstream commit 225734de ] Stas Nichiporovich reported a regression in his HFSC qdisc setup on a non multi queue device. It turns out I mistakenly added a TCQ_F_NOPARENT flag on all qdisc allocated in qdisc_create() for non multi queue devices, which was rather buggy. I was clearly mislead by the TCQ_F_ONETXQUEUE that is also set here for no good reason, since it only matters for the root qdisc.

[ Upstream commit f6548615 ] skb_reorder_vlan_header is called after the vlan header has been pulled. As a result the offset of the begining of the mac header has been incrased by 4 bytes (VLAN_HLEN). When moving the mac addresses, include this incrase in the offset calcualation so that the mac addresses are copied correctly.

[ Upstream commit a6e18ff1 ] When we have multiple stacked vlan devices all of which have turned off REORDER_HEADER flag, the untag operation does not locate the ethernet addresses correctly for nested vlans. The reason is that in case of REORDER_HEADER flag being off, the outer vlan headers are put back and the mac_len is adjusted to account for the presense of the header. Then, the subsequent untag operation, for the next level vlan, always use VLAN_ETH_HLEN to locate the begining of the ethernet header and that ends up being a multiple of 4 bytes short of the actuall beginning of the mac header (the multiple depending on the how many vlan encapsulations ethere are). As a reslult, if there are multiple levles of vlan devices with REODER_HEADER being off, the recevied packets end up being dropped. To solve this, we use skb->mac_len as the offset. The value is always set on receive path and starts out as a ETH_HLEN. The value is also updated when the vlan header manupations occur so we know it will be correct. Signed-off-by:

[ Upstream commit 5037e9ef ] David Wilder reported crashes caused by dst reuse. <quote David> I am seeing a crash on a distro V4.2.3 kernel caused by a double release of a dst_entry. In ipv4_dst_destroy() the call to list_empty() finds a poisoned next pointer, indicating the dst_entry has already been removed from the list and freed. The crash occurs 18 to 24 hours into a run of a network stress exerciser. </quote> Thanks to his detailed report and analysis, we were able to understand the core issue. IP early demux can associate a dst to skb, after a lookup in TCP/UDP sockets. When socket cache is not properly set, we want to store into sk->sk_dst_cache the dst for future IP early demux lookups, by acquiring a stable refcount on the dst. Problem is this acquisition is simply using an atomic_inc(), which works well, unless the dst was queued for destruction from dst_release() noticing dst refcount went to zero, if DST_NOCACHE was set on dst. We need to make sure current refcount is not zero before incrementing it, or risk double free as David reported. This patch, being a stable candidate, adds two new helpers, and use them only from IP early demux problematic paths. It might be possible to merge in net-next skb_dst_force() and skb_dst_force_safe(), but I prefer having the smallest patch for stable kernels : Maybe some skb_dst_force() callers do not expect skb->dst can suddenly be cleared. Can probably be backported back to linux-3.6 kernels Reported-by:

[ Upstream commit 79462ad0 ] 郭永刚 reported that one could simply crash the kernel as root by using a simple program: int socket_fd; struct sockaddr_in addr; addr.sin_port = 0; addr.sin_addr.s_addr = INADDR_ANY; addr.sin_family = 10; socket_fd = socket(10,3,0x40000000); connect(socket_fd , &addr,16); AF_INET, AF_INET6 sockets actually only support 8-bit protocol identifiers. inet_sock's skc_protocol field thus is sized accordingly, thus larger protocol identifiers simply cut off the higher bits and store a zero in the protocol fields. This could lead to e.g. NULL function pointer because as a result of the cut off inet_num is zero and we call down to inet_autobind, which is NULL for raw sockets. kernel: Call Trace: kernel: [<ffffffff816db90e>] ? inet_autobind+0x2e/0x70 kernel: [<ffffffff816db9a4>] inet_dgram_connect+0x54/0x80 kernel: [<ffffffff81645069>] SYSC_connect+0xd9/0x110 kernel: [<ffffffff810ac51b>] ? ptrace_notify+0x5b/0x80 kernel: [<ffffffff810236d8>] ? syscall_trace_enter_phase2+0x108/0x200 kernel: [<ffffffff81645e0e>] SyS_connect+0xe/0x10 kernel: [<ffffffff81779515>] tracesys_phase2+0x84/0x89 I found no particular commit which introduced this problem.

[ Upstream commit 90186af4 ] When an interface is brought up which was previously suspended (via runtime PM), it would hang. This happens because napi_disable is called before napi_enable. Solve this by avoiding napi_enable in the resume during open function (netif_running is true when open is called, IFF_UP is set after a successful open; netif_running is false when close is called, but IFF_UP is then still set). While at it, remove WORK_ENABLE check from rtl8152_open (introduced with the original change) because it cannot happen: - After this patch, runtime resume will not set it during rtl8152_open. - When link is up, rtl8152_open is not called. - When link is down during system/auto suspend/resume, it is not set.

[ Upstream commit 01ce63c9 ] Dmitry Vyukov reported that SCTP was triggering a WARN on socket destroy related to disabling sock timestamp. When SCTP accepts an association or peel one off, it copies sock flags but forgot to call net_enable_timestamp() if a packet timestamping flag was copied, leading to extra calls to net_disable_timestamp() whenever such clones were closed. The fix is to call net_enable_timestamp() whenever we copy a sock with that flag on, like tcp does. Reported-by:

[ Upstream commit cb5e173e ] SCTP echoes a cookie o INIT ACK chunks that contains a timestamp, for detecting stale cookies. This cookie is echoed back to the server by the client and then that timestamp is checked. Thing is, if the listening socket is using packet timestamping, the cookie is encoded with ktime_get() value and checked against ktime_get_real(), as done by __net_timestamp(). The fix is to sctp also use ktime_get_real(), so we can compare bananas with bananas later no matter if packet timestamping was enabled or not.

commit f33a7f72 upstream. Some modems, such as the Telit UE910, are using an Infineon Flash Loader utility. It has two interfaces, 2/2/0 (Abstract Modem) and 10/0/0 (CDC Data). The latter can be used as a serial interface to upgrade the firmware of the modem. However, that isn't possible when the cdc-acm driver takes control of the device. The following is an explanation of the behaviour by Daniele Palmas during discussion on linux-usb.

commit d2f20619 upstream. Commit 53147b6c ("toshiba_acpi: Fix hotkeys registration on some toshiba models") fixed an issue on some laptops regarding hotkeys registration, however, if failed to address the initialization of the hotkey_event_type variable, and thus, it can lead to potential unwanted effects as the variable is being checked. This patch initializes such variable to avoid such unwanted effects. Signed-off-by:

commit 399235dc upstream. Both for FIFO and CRB interface TCG has decided to use the same HID MSFT0101. They can be differentiated by looking at the start method from TPM2 ACPI table. This patches makes necessary fixes to tpm_tis and tpm_crb modules in order to correctly detect, which module should be used. For MSFT0101 we must use struct acpi_driver because struct pnp_driver has a 7 character limitation. It turned out that the root cause in b371616b was not correct for https://bugzilla.kernel.org/show_bug.cgi?id=98181. v2: * One fixup was missing from v1: is_tpm2_fifo -> is_fifo v3: * Use pnp_driver for existing HIDs and acpi_driver only for MSFT0101 in order ensure backwards compatibility. v4: * Check for FIFO before doing *anything* in crb_acpi_add(). * There was return immediately after acpi_bus_unregister_driver() in cleanup_tis(). This caused pnp_unregister_driver() not to be called. Reported-by:

commit 777d738a upstream. create_request_message() computes the maximum length of a message, but uses the wrong type for the time stamp: sizeof(struct timespec) may be 8 or 16 depending on the architecture, while sizeof(struct ceph_timespec) is always 8, and that is what gets put into the message. Found while auditing the uses of timespec for y2038 problems. Fixes: b8e69066 ("ceph: include time stamp in every MDS request") Signed-off-by:

commit c812012f upstream. If we pass in an empty nfs_fattr struct to nfs_update_inode, it will (correctly) not update any of the attributes, but it then clears the NFS_INO_INVALID_ATTR flag, which indicates that the attributes are up to date. Don't clear the flag if the fattr struct has no valid attrs to apply. Reviewed-by:

commit c68a027c upstream. If clp->cl_cb_ident is zero, then nfs_cb_idr_remove_locked() skips removing it when the nfs_client is freed. A decoding or server bug can then find and try to put that first nfs_client which would lead to a crash. Signed-off-by:

commit 0ee9608c upstream. In debugfs' start_creating(), we pin the file system to safely access its root. When we failed to create a file, we unpin the file system via failed_creating() to release the mount count and eventually the reference of the vfsmount. However, when we run into an error during lookup_one_len() when still in start_creating(), we only release the parent's mutex but not so the reference on the mount. Looks like it was done in the past, but after splitting portions of __create_file() into start_creating() and end_creating() via 190afd81 ("debugfs: split the beginning and the end of __create_file() off"), this seemed missed. Noticed during code review. Fixes: 190afd81 ("debugfs: split the beginning and the end of __create_file() off") Signed-off-by:
