2020-08-03mlxsw: spectrum_trap: Add early_drop trapIdo Schimmel
As previously explained, packets that are dropped due to buffer related reasons (e.g., tail drop, early drop) can be mirrored to the CPU port. These packets are then trapped with one of the "mirror session" traps and their CQE includes the reason for which the packet was mirrored. Register with devlink a new trap, early_drop, and initialize the corresponding Rx listener with the appropriate mirror reason. Return an error in case user tries to change the traps' action, as this is not supported. Since Spectrum-1 does not support these traps, the above is only done for Spectrum-2 onwards.

2020-08-03mlxsw: spectrum_span: On policer_id_base_ref_count, use dec_and_testPetr Machata
When unsetting policer base, the SPAN code currently uses refcount_dec(). However that function splats when the counter reaches zero, because reaching zero without actually testing is in general indicative of a missing cleanup. There is no cleanup to be done here, but nonetheless, use refcount_dec_and_test() as required.

2020-08-03tcp: apply a floor of 1 for RTT samples from TCP timestampsJianfeng Wang
For retransmitted packets, TCP needs to resort to using TCP timestamps for computing RTT samples. In the common case where the data and ACK fall in the same 1-millisecond interval, TCP senders with millisecond- granularity TCP timestamps compute a ca_rtt_us of 0. This ca_rtt_us of 0 propagates to rs->rtt_us. This value of 0 can cause performance problems for congestion control modules. For example, in BBR, the zero min_rtt sample can bring the min_rtt and BDP estimate down to 0, reduce snd_cwnd and result in a low throughput. It would be hard to mitigate this with filtering in the congestion control module, because the proper floor to apply would depend on the method of RTT sampling (using timestamp options or internally-saved transmission timestamps). This fix applies a floor of 1 for the RTT sample delta from TCP timestamps, so that seq_rtt_us, ca_rtt_us, and rs->rtt_us will be at least 1 * (USEC_PER_SEC / TCP_TS_HZ). Note that the receiver RTT computation in tcp_rcv_rtt_measure() and min_rtt computation in tcp_update_rtt_min() both already apply a floor of 1 timestamp tick, so this commit makes the code more consistent in avoiding this edge case of a value of 0.

2020-08-04gpio: don't use same lockdep class for all devm_gpiochip_add_data usersAhmad Fatoum
Commit 959bc7b22bd2 ("gpio: Automatically add lockdep keys") documents in its commits message its intention to "create a unique class key for each driver". It does so by having gpiochip_add_data add in-place the definition of two static lockdep classes for LOCKDEP use. That way, every caller of the macro adds their gpiochip with unique lockdep classes. There are many indirect callers of gpiochip_add_data, however, via use of devm_gpiochip_add_data. devm_gpiochip_add_data has external linkage and all its users will share the same lockdep classes, which probably is not intended. Fix this by replicating the gpio_chip_add_data statics-in-macro for the devm_ version as well.
