Here is sequence: 1. TX packet is queued via hard_start_xmit and main_work is queued 2. SDIO interrupt comes in which directly call mwifiex_main_process. This starts executing main superloop. 3. Now work from step1 is scheduled but at first check itself it sees mwifiex_processing is set and exits. 4. Now if superloop from step2 has passed TX processing part of superloop this packet would remain in queue until next packet/command/SDIO interrupt arrives and queues main_work. This patch fixes this corner case by defining more_task flag which is set when mwifiex_processing is found to be true. At end of superloop we again check if more_task flag is set and if set, execute superloop again.

Tracepoints have helper functions for the TP_printk() called __print_symbolic() and __print_flags() that lets a numeric number be displayed as a a human comprehensible text. What is placed in the TP_printk() is also shown in the tracepoint format file such that user space tools like perf and trace-cmd can parse the binary data and express the values too. Unfortunately, the way the TRACE_EVENT() macro works, anything placed in the TP_printk() will be shown pretty much exactly as is. The problem arises when enums are used. That's because unlike macros, enums will not be changed into their values by the C pre-processor. Thus, the enum string is exported to the format file, and this makes it useless for user space tools. The TRACE_DEFINE_ENUM() solves this by converting the enum strings in the TP_printk() format into their number, and that is what is shown to user space. For example, the tracepoint tlb_flush currently has this in its format file: __print_symbolic(REC->reason, { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" }, { TLB_REMOTE_SHOOTDOWN, "remote shootdown" }, { TLB_LOCAL_SHOOTDOWN, "local shootdown" }, { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" }) After adding: TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH); TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN); Its format file will contain this: __print_symbolic(REC->reason, { 0, "flush on task switch" }, { 1, "remote shootdown" }, { 2, "local shootdown" }, { 3, "local mm shootdown" })" * tag 'trace-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (27 commits) tracing: Add enum_map file to show enums that have been mapped writeback: Export enums used by tracepoint to user space v4l: Export enums used by tracepoints to user space SUNRPC: Export enums in tracepoints to user space mm: tracing: Export enums in tracepoints to user space irq/tracing: Export enums in tracepoints to user space f2fs: Export the enums in the tracepoints to userspace net/9p/tracing: Export enums in tracepoints to userspace x86/tlb/trace: Export enums in used by tlb_flush tracepoint tracing/samples: Update the trace-event-sample.h with TRACE_DEFINE_ENUM() tracing: Allow for modules to convert their enums to values tracing: Add TRACE_DEFINE_ENUM() macro to map enums to their values tracing: Update trace-event-sample with TRACE_SYSTEM_VAR documentation tracing: Give system name a pointer brcmsmac: Move each system tracepoints to their own header iwlwifi: Move each system tracepoints to their own header mac80211: Move message tracepoints to their own header tracing: Add TRACE_SYSTEM_VAR to xhci-hcd tracing: Add TRACE_SYSTEM_VAR to kvm-s390 tracing: Add TRACE_SYSTEM_VAR to intel-sst ...

Since the rate scaling algorithm is separate in mac80211, it also invokes the rate scaling algorithm for such stations. It doesn't know that our rate scaling algorithm is tightly integrated with the MVM code and relies on those data structures, and it cannot as the abstraction doesn't allow for it. This leads to crashes when the rate scaling algorithm tries to use uninitialized data, notably the mvmsta->vif pointer. Protect against this in the rate scaling algorithm. We cannot get good rates with such peers anyway since the firmware cannot do anything with them.

When removing the time event the CSA essentially procedure stops, so the safest thing to do is to disconnect in this case.

Instead, cleanup is handled in a tasklet completion routine. Unfortunately, this routine has a serious bug in that it does not release the DMA mapping before it frees the skb, thus one IOMMU mapping is leaked for each beacon. The test system failed with no free IOMMU mapping slots approximately one hour after hostapd was used to start an AP. This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30.
