* rxrpc: Use skb->len not skb->data_lenDavid Howells2016-09-131-4/+4
| | | | | | | | | | | | | 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: David Howells <dhowells@redhat.com>
* rxrpc: Add missing unlock in rxrpc_call_accept()David Howells2016-09-131-3/+5
| | | | | | | Add a missing unlock in rxrpc_call_accept() in the path taken if there's no call to wake up. Signed-off-by: David Howells <dhowells@redhat.com>
* rxrpc: Requeue call for recvmsg if more dataDavid Howells2016-09-131-0/+4
| | | | | | | | | | | | | | 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: David Howells <dhowells@redhat.com>
* rxrpc: The IDLE ACK packet should use rxrpc_idle_ack_delayDavid Howells2016-09-131-1/+1
| | | | | | | The IDLE ACK packet should use the rxrpc_idle_ack_delay setting when the timer is set for it. Signed-off-by: David Howells <dhowells@redhat.com>
* rxrpc: Add missing wakeup on Tx window rotationDavid Howells2016-09-131-0/+2
| | | | | | | | | | | | 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.

* rxrpc: Make sure we initialise the peer hash keyDavid Howells2016-09-131-1/+1
| | | | | | | | | 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: David Howells <dhowells@redhat.com>

* net: bridge: add helper to call /sbin/bridge-stpVivien Didelot2016-09-131-12/+31
| | | | | | | | | | | | | | | | | | | | | | | | | 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: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

Additionally, when the offset values for POST1-4 are left blank, the driver attempts to set them using an offset of 0xFFFF which can cause a memory corruption or panic.

Steps to reproduce: * Suspend (laptop) * Resume (laptop) * Observe that the WLAN led no longer turns ON/OFF depending on the status and is always red Even though for my case it only needs to be set to OUT in ath9k_start but for consistency bring back the IN direction setting as well.

| | | * | brcmfmac: avoid potential stack overflow in brcmf_cfg80211_start_ap()Arend Van Spriel2016-09-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User-space can choose to omit NL80211_ATTR_SSID and only provide raw IE TLV data. When doing so it can provide SSID IE with length exceeding the allowed size. The driver further processes this IE copying it into a local variable without checking the length. Hence stack can be corrupted and used as exploit.
