NAME¶
inode_permission - check for access rights to a given inode
SYNOPSIS¶
int inode_permission(struct inode * inode, int mask);
ARGUMENTS¶
inode
inode to check permission on
mask
right to check for (MAY_READ, MAY_WRITE,
MAY_EXEC)
DESCRIPTION¶
Used to check for read/write/execute permissions on an inode. We use “fsuid” for this, letting us set arbitrary permissions for filesystem access without changing the “normal” uids which are used for other things.
