There are two places that want to transmit a packet in response to one just received and manually pick the address to reply to out of the sk_buff. Make them use rxrpc_extract_addr_from_skb() instead so that IPv6 is handled automatically. Signed-off-by:

Create an address for sendmsg() to bind unbound socket with rather than using a completely blank address otherwise the transport socket creation will fail because it will try to use address family 0. We use the address family specified in the protocol argument when the AF_RXRPC socket was created and SOCK_DGRAM as the default. For anything else, bind() must be used. Signed-off-by:

call->rx_winsize should be initialised to the sysctl setting and the sysctl setting should be limited to the maximum we want to permit. Further, we need to place this in the ACK info instead of the sysctl setting. Furthermore, discard the idea of accepting the subpackets of a jumbo packet that lie beyond the receive window when the first packet of the jumbo is within the window. Just discard the excess subpackets instead. This allows the receive window to be opened up right to the buffer size less one for the dead slot. Signed-off-by:

The preallocated call buffer holds a ref on the calls within that buffer. The ref was being released in the wrong place - it worked okay for incoming calls to the AFS cache manager service, but doesn't work right for incoming calls to a userspace service. Instead of releasing an extra ref service calls in rxrpc_release_call(), the ref needs to be released during the acceptance/rejectance process. To this end: (1) The prealloc ref is now normally released during rxrpc_new_incoming_call(). (2) For preallocated kernel API calls, the kernel API's ref needs to be released when the call is discarded on socket close. (3) We shouldn't take a second ref in rxrpc_accept_call(). (4) rxrpc_recvmsg_new_call() needs to get a ref of its own when it adds the call to the to_be_accepted socket queue. In doing (4) above, we would prefer not to put the call's refcount down to 0 as that entails doing cleanup in softirq context, but it's unlikely as there are several refs held elsewhere, at least one of which must be put by someone in process context calling rxrpc_release_call(). However, it's not a problem if we do have to do that. Signed-off-by:

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:

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:
