  • 821047c40   can: remove CAN FD compatibility for CAN 2.0 sockets ... Browse Code »

    In commit e2d265d3b587 (canfd: add support for CAN FD in CAN_RAW sockets)
    CAN FD frames with a payload length up to 8 byte are passed to legacy
    sockets where the CAN FD support was not enabled by the application.

    After some discussions with developers at a fair this well meant feature
    leads to confusion as no clean switch for CAN / CAN FD is provided to the
    application programmer. Additionally a compatibility like this for legacy
    CAN_RAW sockets requires some compatibility handling for the sending, e.g.
    make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?).

    This will become a mess when people start to develop applications with
    real CAN FD hardware. This patch reverts the bad compatibility code
    together with the documentation describing the removed feature.

  • 0ae89beb2   can: add destructor for self generated skbs ... Browse Code »

    Self generated skbuffs in net/can/bcm.c are setting a skb->sk reference but
    no explicit destructor which is enforced since Linux 3.11 with commit
    376c7311bdb6 (net: add a temporary sanity check in skb_orphan()).

    This patch adds some helper functions to make sure that a destructor is
    properly defined when a sock reference is assigned to a CAN related skb.
    To create an unshared skb owned by the original sock a common helper function
    has been introduced to replace open coded functions to create CAN echo skbs.

  • bb5ecb0c6   can: Propagate SO_PRIORITY of raw sockets to skbs ... Browse Code »

    This allows controlling certain queueing disciplines by setting the
    socket's SO_PRIORITY option.

    For example, with the default pfifo_fast queueing discipline, which
    provides three priorities, socket priority TC_PRIO_CONTROL means
    higher than default and TC_PRIO_BULK means lower than default.

    This is a follow-up patch to f3d3342602f8bc ("net: rework recvmsg
    handler msg_name and msg_namelen logic").

    DECLARE_SOCKADDR validates that the structure we use for writing the
    name information to is not larger than the buffer which is reserved
    for msg->msg_name (which is 128 bytes). Also use DECLARE_SOCKADDR
    consistently in sendmsg code paths.

    The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
    cleanup in net-next to now pass cred structs around.

    The be2net driver had a bug fix in 'net' that overlapped with the VLAN
    interface changes by Patrick McHardy in net-next.

    An IGB conflict existed because in 'net' the build_skb() support was
    reverted, and in 'net-next' there was a comment style fix within that
    code.

    Several batman-adv conflicts were resolved by making sure that all
    calls to batadv_is_my_mac() are changed to have a new bat_priv first
    argument.

    Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
    rewrite in 'net-next', mostly overlapping changes.

    Thanks to Stephen Rothwell and Antonio Quartulli for help with several
    of these merge resolutions.

    Currently, sock_tx_timestamp() always returns 0. The comment that
    describes the sock_tx_timestamp() function wrongly says that it
    returns an error when an invalid argument is passed (from commit
    20d4947353be, ``net: socket infrastructure for SO_TIMESTAMPING'').
    Make the function void, so that we can also remove all the unneeded
    if conditions that check for such a _non-existant_ error case in the
    output path.

  • b67bfe0d4   hlist: drop the node parameter from iterators ... Browse Code »
    26

    I'm not sure why, but the hlist for each entry iterators were conceived

    list_for_each_entry(pos, head, member)

    The hlist ones were greedy and wanted an extra parameter:

    hlist_for_each_entry(tpos, pos, head, member)

    Why did they need an extra pos parameter? I'm not quite sure. Not only
    they don't really need it, it also prevents the iterator from looking
    exactly like the list iterator, which is unfortunate.

    Besides the semantic patch, there was some manual work required:

    - Fix up the actual hlist iterators in linux/list.h
    - Fix up the declaration of other iterators based on the hlist ones.
    - A very small amount of places were using the 'node' parameter, this
    was modified to use 'obj->member' instead.
    - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
    properly, so those had to be fixed up manually.

    The semantic patch which is mostly the work of Peter Senna Tschudin is here:
