Bug ID: 523362
Summary: getpwnam causes a -1 fd to be passed to fstat
Classification: Developer tools
Product: valgrind
Version First unspecified
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
Calling `getpwnam` causes a warning about -1 being passed to fstat
STEPS TO REPRODUCE
1. Create a C file calling getpwnam given any name **not** on the system
2. Compile and run with valgrind
OBSERVED RESULT
`Warning: invalid file descriptor -1 in syscall fstat()` is stated
EXPECTED RESULT
No error, it shouldn't error. Especially on systemd based systems as unix
domain sockets are used for user database functions.
