Re: [Linux-ima-user] One question about the source code of IMA

[Reiner S. <sa...@us...>]

Hi,

d_path is a core linux function and now defined in fs/dcache.c

1818 /* write full pathname into buffer and return start of pathname */
1819 char * d_path(struct dentry *dentry, struct vfsmount *vfsmnt,
1820                                 char *buf, int buflen)
1821 {

See:http://lxr.linux.no/source/fs/dcache.c#L1819

And yes, you are right. D_path offers a simple way to get the absolute 
path name for files we measure.

Greetings
Reiner

[Linux-ima-user] One question about the source code of IMA


Hi Every one,

Within the source code of IMA,
ima_main.c/do_measure_file() function contains a
function called "d_path".

Where this function is defined within the IMA source
code. Apparently, this function takes some struct file
arguments and calculates the name of the file. Am I
right?


Thanks,
MA
