Adjust the call ref tracepoint to show references held on a call by the kernel API separately as much as possible and add an additional trace to at the allocation point from the preallocation buffer for an incoming call. Note that this doesn't show the allocation of a client call for the kernel separately at the moment. Signed-off-by:

Allow tx_winsize to grow when the ACK info packet shows a larger receive window at the other end rather than only permitting it to shrink. Signed-off-by:

skb->len should be used rather than skb->data_len when referring to the amount of data in a packet. This will only cause a malfunction in the following cases: (1) We receive a jumbo packet (validation and splitting both are wrong). (2) We see if there's extra ACK info in an ACK packet (we think it's not there and just ignore it). Signed-off-by:

rxrpc_recvmsg() needs to make sure that the call it has just been processing gets requeued for further attention if the buffer has been filled and there's more data to be consumed. The softirq producer only queues the call and wakes the socket if it fills the first slot in the window, so userspace might end up sleeping forever otherwise, despite there being data available. This is not a problem provided the userspace buffer is big enough or it empties the buffer completely before more data comes in. Signed-off-by:

We need to wake up the sender when Tx window rotation due to an incoming ACK makes space in the buffer otherwise the sender is liable to just hang endlessly. This problem isn't noticeable if the Tx phase transfers no more than will fit in a single window or the Tx window rotates fast enough that it doesn't get full. Signed-off-by:

Peer records created for incoming connections weren't getting their hash key set. This meant that incoming calls wouldn't see more than one DATA packet - which is not a problem for AFS CM calls with small request data blobs. Signed-off-by:

In case port isn't operational we shouldn't report the port type, but instead return PORT_OTHER. This is consistent with most other drivers that return PORT_OTHER when media type can't be determined. Signed-off-by:

If /sbin/bridge-stp is available on the system, bridge tries to execute it instead of the kernel implementation when starting/stopping STP. If anything goes wrong with /sbin/bridge-stp, bridge silently falls back to kernel STP, making hard to debug userspace STP. This patch adds a br_stp_call_user helper to start/stop userspace STP and debug errors from the program: abnormal exit status is stored in the lower byte and normal exit status is stored in higher byte. Below is a simple example on a kernel with dynamic debug enabled: # ln -s /bin/false /sbin/bridge-stp # brctl stp br0 on br0: failed to start userspace STP (256) # dmesg br0: /sbin/bridge-stp exited with code 1 br0: failed to start userspace STP (256) br0: using kernel STP Signed-off-by:
