2018-06-15stmmac: added support for 802.1ad vlan strippingElad Nachman
stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before calling napi_gro_receive(). The function assumes VLAN tagged frames are always tagged with 802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding the parameter on call to __vlan_hwaccel_put_tag() . This causes packets not to be passed to the VLAN slave if it was created with 802.1AD protocol (ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100). This fix passes the protocol from the VLAN header into __vlan_hwaccel_put_tag() instead of using the hard-coded value of ETH_P_8021Q. NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now dependent on the correct combination of features and the detected vlan tag. NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver actual abilities.

2018-06-15afs: Optimise callback breaking by not repeating volume lookupDavid Howells
At the moment, afs_break_callbacks calls afs_break_one_callback() for each separate FID it was given, and the latter looks up the volume individually for each one. However, this is inefficient if two or more FIDs have the same vid as we could reuse the volume. This is complicated by cell aliasing whereby we may have multiple cells sharing a volume and can therefore have multiple callback interests for any particular volume ID. At the moment afs_break_one_callback() scans the entire list of volumes we're getting from a server and breaks the appropriate callback in every matching volume, regardless of cell. This scan is done for every FID. Optimise callback breaking by the following means: (1) Sort the FID list by vid so that all FIDs belonging to the same volume are clumped together. This is done through the use of an indirection table as we cannot do an insertion sort on the afs_callback_break array as we decode FIDs into it as we subsequently also have to decode callback info into it that corresponds by array index only. We also don't really want to bubblesort afterwards if we can avoid it. (2) Sort the server->cb_interests array by vid so that all the matching volumes are grouped together. This permits the scan to stop after finding a record that has a higher vid. (3) When breaking FIDs, we try to keep server->cb_break_lock as long as possible, caching the start point in the array for that volume group as long as possible. It might make sense to add another layer in that list and have a refcounted volume ID anchor that has the matching interests attached to it rather than being in the list. This would allow the lock to be dropped without losing the cursor. Signed-off-by: David Howells <dhowells@redhat.com>
2018-06-15afs: Display manually added cells in dynamic root mountDavid Howells
Alter the dynroot mount so that cells created by manipulation of /proc/fs/afs/cells and /proc/fs/afs/rootcell and by specification of a root cell as a module parameter will cause directories for those cells to be created in the dynamic root superblock for the network namespace[*]. To this end: (1) Only one dynamic root superblock is now created per network namespace and this is shared between all attempts to mount it. This makes it easier to find the superblock to modify. (2) When a dynamic root superblock is created, the list of cells is walked and directories created for each cell already defined. (3) When a new cell is added, if a dynamic root superblock exists, a directory is created for it. (4) When a cell is destroyed, the directory is removed. (5) These directories are created by calling lookup_one_len() on the root dir which automatically creates them if they don't exist. [*] Inasmuch as network namespaces are currently supported here.

2018-06-15cfg80211: initialize sinfo in cfg80211_get_stationSven Eckelmann
Most of the implementations behind cfg80211_get_station will not initialize sinfo to zero before manipulating it. For example, the member "filled", which indicates the filled in parts of this struct, is often only modified by enabling certain bits in the bitfield while keeping the remaining bits in their original state. A caller without a preinitialized sinfo.filled can then no longer decide which parts of sinfo were filled in by cfg80211_get_station (or actually the underlying implementations). cfg80211_get_station must therefore take care that sinfo is initialized to zero. Otherwise, the caller may tries to read information which was not filled in and which must therefore also be considered uninitialized. In batadv_v_elp_get_throughput's case, an invalid "random" expected throughput may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may switch to non-optimal neighbors for certain destinations.

If 'fd' is negative, l2tp_tunnel_create() creates a tunnel socket using the configuration passed in 'tcfg'. Currently, pppol2tp_connect() sets the relevant fields to zero, tricking l2tp_tunnel_create() into setting up an unusable kernel socket. We can't set 'tcfg' with the required fields because there's no way to get them from the current connect() parameters. So let's restrict kernel sockets creation to the netlink API, which is the original use case.

Not setting the pseudo-wire type had several annoying effects: * Invalid value returned in the L2TP_ATTR_PW_TYPE attribute when dumping sessions with the netlink API. * Impossibility to delete the session using the netlink API (because l2tp_nl_cmd_session_delete() gets the deletion callback function from an array indexed by the session's pseudo-wire type). Also, there are several cases where we should check a session's pseudo-wire type. For example, pppol2tp_connect() should refuse to connect a session that is not PPPoL2TP, but that requires the session's .pwtype field to be properly set.

2018-06-14tcp: verify the checksum of the first data segment in a new connectionFrank van der Linden
commit 079096f103fa ("tcp/dccp: install syn_recv requests into ehash table") introduced an optimization for the handling of child sockets created for a new TCP connection. But this optimization passes any data associated with the last ACK of the connection handshake up the stack without verifying its checksum, because it calls tcp_child_process(), which in turn calls tcp_rcv_state_process() directly. These lower-level processing functions do not do any checksum verification. Insert a tcp_checksum_complete call in the TCP_NEW_SYN_RECEIVE path to fix this.

If the test_printf module is loaded before the crng is initialized, the plain 'p' tests will fail because the printed address will not be hashed and the buffer will contain '(ptrval)' instead. This patch adds a call to wait_for_random_bytes() before plain 'p' tests to make sure the crng is initialized.

Hexagon arch does not seem to have subscribed to _HAVE_COLOR_ZERO_PAGE framework. Hence zero_page_mask variable is not needed.

2018-06-15mm: fix oom_kill event handlingRoman Gushchin
Commit e27be240df53 ("mm: memcg: make sure memory.events is uptodate when waking pollers") converted most of memcg event counters to per-memcg atomics, which made them less confusing for a user. The "oom_kill" counter remained untouched, so now it behaves differently than other counters (including "oom"). This adds nothing but confusion. Let's fix this by adding the MEMCG_OOM_KILL event, and follow the MEMCG_OOM approach. This also removes a hack from count_memcg_event_mm(), introduced earlier specially for the OOM_KILL counter.

2018-06-15mm: use octal not symbolic permissionsJoe Perches
mm/*.c files use symbolic and octal styles for permissions. Using octal and not symbolic permissions is preferred by many as more readable. https://lkml.org/lkml/2016/8/2/1945 Prefer the direct use of octal for permissions. Done using $ scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace mm/*.c and some typing. Before: $ git grep -P -w "0[0-7]{3,3}" mm | wc -l 44 After: $ git grep -P -w "0[0-7]{3,3}" mm | wc -l 86 Miscellanea: o Whitespace neatening around these conversions.

2018-06-15ipc: use new return type vm_fault_tSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type.
