Message-Id: <20151212.190615.2226584145922779613.davem@davemloft.net> Date: Sat, 12 Dec 2015 19:06:15 -0500 (EST) From: David Miller <davem@...emloft.net> To: daniel@...earbox.net Cc: ast@...nel.org, netdev@...r.kernel.org Subject: Re: [PATCH net-next] bpf, inode: allow for rename and link ops From: Daniel Borkmann <daniel@...earbox.net> Date: Thu, 10 Dec 2015 22:33:49 +0100 > Add support for renaming and hard links to the fs. Most of this can be > implemented by using simple library operations under the same constraints > that we don't use a reserved name like elsewhere. Linking can be useful > to share/manage things like maps across subsystem users. It works within > the file system boundary, but is not allowed for directories. > > Symbolic links are explicitly not implemented here, as it can be better > done already by doing bind mounts inside bpf fs to set up shared directories > f.e. useful when using volumes in docker containers that map a private > working directory into /sys/fs/bpf/ which contains itself a bind mounted > path from the host's /sys/fs/bpf/ mount that is shared among multiple > containers. For single maps instead of whole directory, hard links can > be easily used to do the same. > > Signed-off-by: Daniel Borkmann <daniel@...earbox.net> > Acked-by: Alexei Starovoitov <ast@...nel.org> Applied, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
