Dear kernelnewbies subscribers,
I was reading the kernel source tree in an attempt to understand how the chroot syscall workes. (I was using the linux-6.17-rc3 tarball from kernel.org.)
At line 1429 of the fs/open.c file, inside the definition of the do_sys_openat2() function getname() is called.
I am having trouble finding its definition.
In particular, $ grep -rn 'getname' fs doesn't return a line like 'struct file *getname (args)' or similar, as I would expect.
Can someone point me to the file/line where getname() is defined?
You can use GNU Global [1] to find definition and references. $ make gtags $ global -x getname getname 2916 include/linux/fs.h static inline struct filename *getname(const char __user *name) $ global -xr getname getname 484 crypto/af_alg.c .getname = sock_no_getname, ... <snip> [1] https://www.gnu.org/software/global/
Thank you, Vulturus
