| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On reading the ext_csd for the first time (in 1 bit mode), save the ext_csd information needed for bus width compare. On every pass we make re-reading the ext_csd, compare the data against the saved ext_csd data. This fixes a regression introduced in 3.0-rc1 by 08ee80cc397ac1a3 ("mmc: core: eMMC bus width may not work on all platforms"), which incorrectly assumed we would be re-reading the ext_csd at resume- time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because struct rpcbind_args *map was declared static, if two threads entered this method at the same time, the values assigned to map could be sent two two differen tasks. This could cause all sorts of problems, include use-after-free and double-free of memory. Fix this by removing the static declaration so that the map pointer is on the stack.

This behavior is already practiced in TCP. We do not check the input queue because that would mean to parse all chunks on it to look for unacknowledged data which seems too much of an effort. Control chunks or duplicated chunks may also be in the input queue and should not be stopping a graceful shutdown.

When no QoS field is present, zero is used as the TID value. This means that it is possible for an attacker to take a QoS packet with TID 0 and replay it as a non-QoS packet. Unfortunately, mac80211 uses different IVs for checking the validity of the packet's TKIP IV when it checks TID 0 and when it checks non-QoS packets. This means it is vulnerable to this replay attack. To fix this, use the same replay counter for TID 0 and non-QoS packets by overriding the rx->queue value to 0 if it is 16 (non-QoS). This is a minimal fix for now.

When the hidp session thread was converted from kernel_thread to kthread, the atomic/wakeups were replaced with kthread_stop. kthread_stop has blocking semantics which are inappropriate for the hidp session kthread. In addition, the kthread signals itself to terminate in hidp_process_hid_control() - it cannot do this with kthread_stop(). Lastly, a wakeup can be lost if the wakeup happens between checking for the loop exit condition and setting the current state to TASK_INTERRUPTIBLE. (Without appropriate synchronization mechanisms, the task state should not be changed between the condition test and the yield - via schedule() - as this creates a race between the wakeup and resetting the state back to interruptible.)

The graceful shutdown will wait for all outstanding TSN to be acknowledged before sending the SHUTDOWN request. This never happens due to the peer's zero window not acknowledging the continuously retransmitted data chunks. Although the error counter is incremented for each failed retransmission, the receiving of the SACK announcing the zero window clears the error count again immediately. Also heartbeat requests continue to be sent periodically. The peer acknowledges these requests causing the error counter to be reset as well. This patch changes behaviour to only reset the overall error counter for the above rules while not in shutdown. After reaching the maximum number of retransmission attempts, the T5 shutdown guard timer is scheduled to give the receiver some additional time to recover. The timer is stopped as soon as the receiver acknowledges any data. The issue can be easily reproduced by establishing a sctp association over the loopback device, constantly queueing data at the sender while not reading any at the receiver. Wait for the window to reach zero, then initiate a shutdown by killing both processes simultaneously. The association will never be freed and the chunks on the retransmission queue will be retransmitted indefinitely.

This cleans up the implementation of that function, fixing a bug or two while at it, so that it's harmless (and potentially useful) for other platforms. Without this, bugs in that code would trigger a WARN_ON() in drivers/base/memory.c when booting some different platforms. If/when we have another platform supporting memory hotplug we might want to either move that out to a generic place or make it a ppc_md. callback.
