Bug ID: 19701
Summary: Restore errno around signal handlers
Product: glibc
Version: 2.24
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Future POSIX versions allow preserving the errno variable of the interrupted
thread in a signal handler. We should implement this because a lot of
application code does not handle this correctly, which can result in
difficult-to-debug rare failures.
