In linux/fs/ext2/file.c in kernel 2.1.9:
static inline void remove_suid(struct inode *inode) { unsigned int mode;
/* set S_IGID if S_IXGRP is set, and always set S_ISUID */ mode = (inode->i_mode & S_IXGRP)*(S_ISGID/S_IXGRP) | S_ISUID;
/* was any of the uid bits set? */ mode &= inode->i_mode; if (mode && suser()) { inode->i_mode &= ~mode; inode->i_dirt = 1; } }
It should be !suser() (as it was before this code moved out of fs/read_write.c).
