Bug ID: 506970
Summary: mmap needs an EBADF fd_allowed check
Classification: Developer tools
Product: valgrind
Version First 3.25.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
The LTP mmap08 testcase fails with:
mmap08.c:28: TFAIL: mmap(NULL, page_sz, PROT_WRITE, MAP_FILE | MAP_SHARED, fd,
0) expected EBADF: EINVAL (22)
The test closes fd before calling mmap and expects EBADF not EINVAL.
There should probably be a fd_allowed check on arg5 in
ML_(generic_PRE_sys_mmap)
