2021-03-15net: hdlc_x25: Prevent racing between "x25_close" and "x25_xmit"/"x25_rx"Xie He1-1/+41
"x25_close" is called by "hdlc_close" in "hdlc.c", which is called by hardware drivers' "ndo_stop" function. "x25_xmit" is called by "hdlc_start_xmit" in "hdlc.c", which is hardware drivers' "ndo_start_xmit" function. "x25_rx" is called by "hdlc_rcv" in "hdlc.c", which receives HDLC frames from "net/core/dev.c". "x25_close" races with "x25_xmit" and "x25_rx" because their callers race. However, we need to ensure that the LAPB APIs called in "x25_xmit" and "x25_rx" are called before "lapb_unregister" is called in "x25_close". This patch adds locking to ensure when "x25_xmit" and "x25_rx" are doing their work, "lapb_unregister" is not yet called in "x25_close". Reasons for not solving the racing between "x25_close" and "x25_xmit" by calling "netif_tx_disable" in "x25_close": 1. We still need to solve the racing between "x25_close" and "x25_rx"; 2. The design of the HDLC subsystem assumes the HDLC hardware drivers have full control over the TX queue, and the HDLC protocol drivers (like this driver) have no control. Controlling the queue here in the protocol driver may interfere with hardware drivers' control of the queue.

2021-03-15rtw88: 8822c: support FW crash dump when FW crashZong-Zhe Yang7-14/+172
Although FW crash logs are already supported for dumping in driver, the logs may not be sufficient to analyze field issues. To improve this part, we add a support to dump FW memory. When driver receives FW crash notifications, driver uses DDMA, which is a HW ability, to copy specified FW memory to FW fifo. Driver can then dump these information from FW fifo. With this support, not only FW crash log but also specified FW memory will be dumped while FW crash. Besides, specified registers are also dumped. This feature is implemeted on 8822C first due to difference of FW layouts between ICs. In addition, we add a debugfs to trigger FW crash. It can simulate the process of crash, dump and reset. Through it, we can also check if a reset is ongoing.

2021-03-13netdevsim: Allow reporting activity on nexthop bucketsIdo Schimmel1-0/+61
A key component of the resilient hashing algorithm is the hash buckets' activity. If a bucket is active, it will not be populated with a new nexthop in order not to break existing flows. Therefore, in order to easily and thoroughly test the algorithm, we need to be in full control over the reported activity. Add a debugfs interface that allows user space to have netdevsim report a nexthop bucket within a resilient nexthop group as active. For example: # echo 10 23 > /sys/kernel/debug/netdevsim/netdevsim10/fib/nexthop_bucket_activity Will mark bucket 23 in nexthop group 10 as active.

2021-03-13netdevsim: Add support for resilient nexthop groupsIdo Schimmel1-0/+55
Allow resilient nexthop groups to be programmed and account their occupancy according to their number of buckets. The nexthop group itself as well as its buckets are marked with hardware flags (i.e., 'RTNH_F_TRAP'). Replacement of a single nexthop bucket can fail using the following debugfs knob: # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace N # echo 1 > /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_nexthop_bucket_replace Y Replacement of a resilient nexthop group can fail using the following debugfs knob: # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace N # echo 1 > /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace # cat /sys/kernel/debug/netdevsim/netdevsim10/fib/fail_res_nexthop_group_replace Y This enables testing of various error paths.

2021-03-13netdevsim: Create a helper for setting nexthop hardware flagsIdo Schimmel1-3/+10
Instead of calling nexthop_set_hw_flags(), call a helper. It will be used to also set nexthop bucket flags in a subsequent patch.

2021-03-13netdevsim: fib: Introduce a lock to guard nexthop hashtablePetr Machata1-3/+7
Currently netdevsim relies on RTNL to maintain exclusivity in accessing the nexthop hash table. However, bucket notification may be called without RTNL having been held. Instead, introduce a custom lock to guard the table. Signed-off-by: Petr Machata <petrm@nvidia.com> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
