Bug ID: 502359
Summary: Add --modify-fds=strict option
Classification: Developer tools
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: ahajk...@redhat.com
Target Milestone: ---
Normally a newly recreated file descriptor gets the lowest available number.
This might cause old file descriptor numbers to be reused and hides bad file
descriptor accesses (because the old number is new again).
Using --modify-fds=high option makes Valgrind to get a new file descriptors
that is ahighest availablenot yet before number. This is implemented by making
record_fd_open* return a new file descriptor (by dupping the given file
descriptor only a higher never used before number and closing the one returned
from the kernel) and returning that to the application.
Using --modify-fds=strict makes an exception for file descriptors 0, 1, 2 which
programs might explicitly want to reassign.
