net: SO_RCVMARK socket option for SO_MARK with recvmsg()

2022-04-28T20:08:15Z

Adding a new socket option, SO_RCVMARK, to indicate that SO_MARK should be included in the ancillary data returned by recvmsg(). Renamed the sock_recv_ts_and_drops() function to sock_recv_cmsgs().

net: remove noblock parameter from skb_recv_datagram()

2022-04-06T12:45:26Z

skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side. One missing conversion thankfully reported by kernel test robot. I missed to enable kunit tests to build the mctp code.

Bluetooth: Add support for BT_PKT_STATUS CMSG data for SCO connections

2020-06-12T13:08:49Z

This change adds support for reporting the BT_PKT_STATUS to the socket CMSG data to allow the implementation of a packet loss correction on erroneous data received on the SCO socket. The patch was partially developed by Marcel Holtmann and validated by Hsin-yu Chao. Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann

Bluetooth: Removing noisy dbg message

2020-06-03T17:53:25Z

This patch removes a particularly noisy dbg message. The debug message isn't particularly interesting for debuggability so it was simply removed to reduce noise in dbg logs. Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann

net: use skb_queue_empty_lockless() in poll() handlers

Many poll() handlers are lockless. Using skb_queue_empty_lockless() instead of skb_queue_empty() is more appropriate. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: rework SIOCGSTAMP ioctl handling

2019-04-19T21:07:40Z

The SIOCGSTAMP/SIOCGSTAMPNS ioctl commands are implemented by many socket protocol handlers, and all of those end up calling the same sock_get_timestamp()/sock_get_timestampns() helper functions, which results in a lot of duplicate code. With the introduction of 64-bit time_t on 32-bit architectures, this gets worse, as we then need four different ioctl commands in each socket protocol implementation. To simplify that, let's add a new .gettstamp() operation in struct proto_ops, and move ioctl implementation into the common sock_ioctl()/compat_sock_ioctl_trans() functions that these all go through. We can reuse the sock_get_timestamp() implementation, but generalize it so it can deal with both native and compat mode, as well as timeval and timespec structures.
