Subject: Re: Ответ: VFS, NFS security bug? Should CAP_MKNOD and CAP_LINUX_IMMUTABLE be added to CAP_FS_MASK?

Anyway, please commit changes to linux-2.4 too.

fs/nfsd/auth.c for CAP_NFSD_MASK:
#define	CAP_NFSD_MASK (CAP_FS_MASK|CAP_TO_MASK(CAP_SYS_RESOURCE))

and

include/linux/capability.h for CAP_FS_MASK:
#define CAP_FS_MASK          0x1f
