[Bug 1808565] Re: Reading /proc/self/task/<pid>/maps is not remapped to the target

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  Reading /proc/self/task/<pid>/maps is not remapped to the target

Status in QEMU:
  Incomplete

Bug description:
  Seeing this in qemu-user 3.1.0

  The code in is_proc_myself which supports remapping of /proc/self/maps
  and /proc/<pid>/maps does not support remapping of
  /proc/self/task/<pid>/maps or /proc/<pid>/task/<pid>/maps. Extending
  is_proc_myself to cover these cases causes the maps to be rewritten
  correctly.

  These are useful in multithreaded programs to avoid freezing the
  entire program to capture the maps for a single tid.
