The first iteration of the dwmac-rk support did access an intermediate clock directly below the pll selector. This was removed in a subsequent revision, but the clock and one invocation remained. This results in the driver trying to set the rate of a non-existent clock when the soc and not some external source provides the phy clock for RMII phys. So set the rate of the correct clock and remove the remaining now completely unused definition.

In a first version the driver did want to do some gpio wiggling, which of course never made it into the kernel, but somehow these register defines where forgotten. Remove them, as they shouldn't be here. Signed-off-by:

Add code to nf_unregister_hook to flush the nf_queue when a hook is unregistered. This guarantees that the pointer that the nf_queue code retains into the nf_hook list will remain valid while a packet is queued. I tested what would happen if we do not flush queued packets and was trivially able to obtain the oops below. All that was required was to stop the nf_queue listening process, to delete all of the nf_tables, and to awaken the nf_queue listening process. > BUG: unable to handle kernel paging request at 0000000100000001 > IP: [<0000000100000001>] 0x100000001 > PGD b9c35067 PUD 0 > Oops: 0010 [#1] SMP > Modules linked in: > CPU: 0 PID: 519 Comm: lt-nfqnl_test Not tainted > task: ffff8800b9c8c050 ti: ffff8800ba9d8000 task.ti: ffff8800ba9d8000 > RIP: 0010:[<0000000100000001>] [<0000000100000001>] 0x100000001 > RSP: 0018:ffff8800ba9dba40 EFLAGS: 00010a16 > RAX: ffff8800bab48a00 RBX: ffff8800ba9dba90 RCX: ffff8800ba9dba90 > RDX: ffff8800b9c10128 RSI: ffff8800ba940900 RDI: ffff8800bab48a00 > RBP: ffff8800b9c10128 R08: ffffffff82976660 R09: ffff8800ba9dbb28 > R10: dead000000100100 R11: dead000000200200 R12: ffff8800ba940900 > R13: ffffffff8313fd50 R14: ffff8800b9c95200 R15: 0000000000000000 > FS: 00007fb91fc34700(0000) GS:ffff8800bfa00000(0000) knlGS:0000000000000000 > CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 > CR2: 0000000100000001 CR3: 00000000babfb000 CR4: 00000000000007f0 > Stack: > ffffffff8206ab0f ffffffff82982240 ffff8800bab48a00 ffff8800b9c100a8 > ffff8800b9c10100 0000000000000001 ffff8800ba940900 ffff8800b9c10128 > ffffffff8206bd65 ffff8800bfb0d5e0 ffff8800bab48a00 0000000000014dc0 > Call Trace: > [<ffffffff8206ab0f>] ? nf_iterate+0x4f/0xa0 > [<ffffffff8206bd65>] ? nf_reinject+0x125/0x190 > [<ffffffff8206dee5>] ? nfqnl_recv_verdict+0x255/0x360 > [<ffffffff81386290>] ? nla_parse+0x80/0xf0 > [<ffffffff8206c42c>] ? nfnetlink_rcv_msg+0x13c/0x240 > [<ffffffff811b2fec>] ? __memcg_kmem_get_cache+0x4c/0x150 > [<ffffffff8206c2f0>] ? nfnl_lock+0x20/0x20 > [<ffffffff82068159>] ? netlink_rcv_skb+0xa9/0xc0 > [<ffffffff820677bf>] ? netlink_unicast+0x12f/0x1c0 > [<ffffffff82067ade>] ? netlink_sendmsg+0x28e/0x650 > [<ffffffff81fdd814>] ? sock_sendmsg+0x44/0x50 > [<ffffffff81fde07b>] ? ___sys_sendmsg+0x2ab/0x2c0 > [<ffffffff810e8f73>] ? __wake_up+0x43/0x70 > [<ffffffff8141a134>] ? tty_write+0x1c4/0x2a0 > [<ffffffff81fde9f4>] ? __sys_sendmsg+0x44/0x80 > [<ffffffff823ff8d7>] ? system_call_fastpath+0x12/0x6a > Code: Bad RIP value. > RIP [<0000000100000001>] 0x100000001 > RSP <ffff8800ba9dba40> > CR2: 0000000100000001 > ---[ end trace 08eb65d42362793f ]--- Cc: stable@vger.kernel.org Signed-off-by:

BPF offers another way to generate latency histograms. We attach kprobes at trace_preempt_off and trace_preempt_on and calculate the time it takes to from seeing the off/on transition. The first array is used to store the start time stamp. The key is the CPU id. The second array stores the log2(time diff). We need to use static allocation here (array and not hash tables). The kprobes hooking into trace_preempt_on|off should not calling any dynamic memory allocation or free path. We need to avoid recursivly getting called. Besides that, it reduces jitter in the measurement.

When STP is running in user-space and querier is configured, the querier timer is not started when a port goes to a non-blocking state. This patch unifies the user- and kernel-space stp multicast port enable path and enables it in all states different from blocking. Note that when a port goes in BR_STATE_DISABLED it's not enabled because that is handled in the beginning of the port list loop. Signed-off-by:

Actor and Partner details can be accessed via proc-fs, sys-fs entries or netlink interface. These interfaces are world readable at this moment. The earlier patch-series made the LACP communication secure to avoid nuisance attack from within the same L2 domain but it did not prevent "someone unprivileged" looking at that information on host and perform the same act. This patch essentially avoids spitting those entries if the user in question does not have enough privileges. Signed-off-by:

This patch adds getsockopt(SOL_NETLINK, NETLINK_LIST_MEMBERSHIPS) to retrieve all groups a socket is a member of. Currently, we have to use getsockname() and look at the nl.nl_groups bitmask. However, this mask is limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and NETLINK_DROP_MEMBERSHIP, this adds a separate sockopt to manager higher groups IDs than 32. This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the size of the array. The array is filled with the full membership-set of the socket, and the required array size is returned in optlen. Hence, user-space can retry with a properly sized array in case it was too small.

When an inet_sock is destroyed, its source port (sk_num) is set to zero as part of the unhash procedure. In order to supply a source port as part of the NETLINK_SOCK_DIAG socket destruction broadcasts, the source port number must be read from inet_sport instead. Tested: ss -E Signed-off-by:
