Public bug reported:
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.

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. ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1808565 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.
