2021-06-18tracing: Do not stop recording cmdlines when tracing is offSteven Rostedt (VMware)
The saved_cmdlines is used to map pids to the task name, such that the output of the tracing does not just show pids, but also gives a human readable name for the task. If the name is not mapped, the output looks like this: <...>-1316 [005] ...2 132.044039: ... Instead of this: gnome-shell-1316 [005] ...2 132.044039: ... The names are updated when tracing is running, but are skipped if tracing is stopped. Unfortunately, this stops the recording of the names if the top level tracer is stopped, and not if there's other tracers active. The recording of a name only happens when a new event is written into a ring buffer, so there is no need to test if tracing is on or not. If tracing is off, then no event is written and no need to test if tracing is off or not. Remove the check, as it hides the names of tasks for events in the instance buffers.

2021-06-18mac80211: handle various extensible elements correctlyJohannes Berg

2021-06-18cfg80211: avoid double free of PMSR requestAvraham Stern
If cfg80211_pmsr_process_abort() moves all the PMSR requests that need to be freed into a local list before aborting and freeing them. As a result, it is possible that cfg80211_pmsr_complete() will run in parallel and free the same PMSR request. Fix it by freeing the request in cfg80211_pmsr_complete() only if it is still in the original pmsr list.

2021-06-17net: qed: Fix memcpy() overflow of qed_dcbx_params()Kees Cook
The source (&dcbx_info->operational.params) and dest (&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params (560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used as the memcpy() size. However it seems that struct qed_dcbx_operational_params (dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params (p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte for "valid"). On the assumption that the size is wrong (rather than the source structure type), adjust the memcpy() size argument to be 4 bytes smaller and add a BUILD_BUG_ON() to validate any changes to the structure sizes.

2021-06-17net: gianfar: Implement rx_missed_errors counterEsben Haabendal
Devices with RMON support has a 16-bit RDRP counter. It provides: "Receive dropped packets counter. Increments for frames received which are streamed to system but are later dropped due to lack of system resources." To handle more than 2^16 dropped packets, a carry bit in CAR1 register is set on overflow, so we enable irq when this is set, extending the counter to 2^64 for handling situations where lots of packets are missed (e.g. during heavy network storms).

My local syzbot instance hit memory leak in mkiss_open()[1]. The problem was in missing free_netdev() in mkiss_close(). In mkiss_open() netdevice is allocated and then registered, but in mkiss_close() netdevice was only unregistered, but not freed.
