Currently sym and dso require printing ip and addr because the print function is tied to those outputs. With callindent it makes sense to print the symbol or dso without numerical IP or ADDR. So change the dependency check to only check the underlying attribute. Also the branch target output relies on the user_set flag to determine if the branch target should be implicitely printed. When modifying the fields with + or - also set user_set, so that ADDR can be removed. We also need to set wildcard_set to make the initial sanity check pass. This allows to remove a lot of noise in callindent output by dropping the numerical addresses, which are not all that useful.

Stephane reported a possible issue in the ordered events code, which could lead to allocating more memory than guarded by max_alloc_size. He also suggested the fix to properly check that the new size is below the max_alloc_size limit.

When ordering events, we use preallocated buffers to store separate events. Those buffers currently don't have their own struct, but since they are basically an array of 'struct ordered_event' objects, we use the first event to hold buffers data - list head, that holds all buffers together: struct ordered_events { ... struct ordered_event *buffer; ... }; struct ordered_event { u64 timestamp; u64 file_offset; union perf_event *event; struct list_head list; }; This is quite convoluted and error prone as demonstrated by free-ing issue discovered and fixed by Stephane in here [1]. This patch adds the 'struct ordered_events_buffer' object, that holds the buffer data and frees it up properly.

It has been pointed out to me many times that it is useful to be able to switch off AUX records to save the bandwidth for records that actually matter, for example, in AUX overwrite mode. The usefulness of PERF_RECORD_AUX is in some of its flags, like the TRUNCATED flag that tells the decoder where exactly gaps in the trace are. The OVERWRITE flag, on the other hand will be set on every single record in overwrite mode. However, a PERF_RECORD_AUX[flags=OVERWRITE] is generated on every target task's sched_out, which over time adds up to a lot of useless information. If any folks out there have userspace that depends on a constant stream of OVERWRITE records for a good reason, they'll have to let us know.

Commit 1c5aae77 ("perf machine: Create maps for x86 PTI entry trampolines") revealed a problem with maps__find_symbol_by_name() that resulted in probes not being found e.g. $ sudo perf probe xsk_mmap xsk_mmap is out of .text, skip it. Probe point 'xsk_mmap' not found. Error: Failed to add events. maps__find_symbol_by_name() can optionally return the map of the found symbol. It can get the map wrong because, in fact, the symbol is found on the map's dso, not allowing for the possibility that the dso has more than one map. Fix by always checking the map contains the symbol.
