I'm writing net raid FS with FUSE on ubuntu. Here are syscalls I've implemented: create
open
read
write
release
unlink
mkdir
opendir
readdir
releasedir
rmdir
getattr
and rename
.
Everything works fine, but here is such case: I wrote "hello world" in c and tried typing this: gcc hello.c -o a.out
. a.out
is fine, but it's just a file, not executable (When I set manually 0777 permissions it executes fine on ./a.out
).
When permissions must be set, and how? And when compiling, how to know which files should be set exe permissions? Based on what?
I lacked chmod
syscall implementation. chmod
makes it work all right. Thanks @Barmar for help!
