2 years agobluetooth: don't use bitmaps for random flag accesses
Linus Torvalds [Sun, 5 Jun 2022 18:51:48 +0000 (11:51 -0700)]
bluetooth: don't use bitmaps for random flag accesses

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.

It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32.  It shoudln't have been a bitmap in the first
place.  The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.

The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.

So just use a regular integer.

In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).

That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

Pull more perf tools updates from Arnaldo Carvalho de Melo:

 - Synthesize task events for pre-existing threads when using 'perf lock
   --threads', as we need to show task names.

 - Fix unwinding with ld.lld (>= version 10.0) linked objects, where
  .eh_frame_hdr and .text are in different PT_LOAD program headers,
   which makes perf record --call-graph dwarf fail with such obkects.

 - Check if 'perf record' hangs in the ARM SPE (Statistical Profiling
   Extensions) 'perf test' entry when recording a workload with forks.

 - Trace physical address for Arm SPE events, needed for 'perf c2c' to
   locate the memory node for samples.

 - Fix sorting in percent_rmt_hitm_cmp() in 'perf c2c'.

 - Further support for Intel hybrid systems in the evlist and 'perf
   record' code.

 - Update IBM s/390 vendor event JSON tables.

 - Add metrics (JSON) for Intel Sapphirerapids.

 - Update metrics for Intel Alderlake.

 - Correct typo of sysf 'event_source' directory in the documentation.
