2012-08-15C6X: select GENERIC_ATOMIC64Mark Salter
The generic atomic64 support came in 2009 to support the perf subsystem with the expectation that all architectures would implement atomic64 support. Since then, other optional parts of the generic kernel have also come to expect atomic64 support. This patch enables generic atomic64 support for C6X architecture.

2012-08-15C6X: add Lx_CACHE_SHIFT definesMark Salter
C6X currently lacks Lx_CACHE_SHIFT defines which are needed in a few places in the generic kernel. This patch adds _SHIFT defines for the various caches and bases the Lx_CACHE_BYTES defines on them. Signed-off-by: Mark Salter <msalter@redhat.com>
2012-08-15regulator: twl-regulator: fix up VINTANA1/VINTANA2Aaro Koskinen
It seems commit 2098e95ce9bb039ff2e7bf836df358d18a176139 (regulator: twl: adapt twl-regulator driver to dt) accidentally deleted VINTANA1. Also the same commit defines VINTANA2 twice with TWL4030_ADJUSTABLE_LDO and TWL4030_FIXED_LDO. This patch changes the fixed one to be VINTANA1. I noticed this when auditing my N900 boot logs. I could not notice any change in device behaviour, though, except that the boot logs are now like before: ...

2012-08-15vfs: canonicalize create mode in build_open_flags()Miklos Szeredi
Userspace can pass weird create mode in open(2) that we canonicalize to "(mode & S_IALLUGO) | S_IFREG" in vfs_create(). The problem is that we use the uncanonicalized mode before calling vfs_create() with unforseen consequences. So do the canonicalization early in build_open_flags().

2012-08-15audit: clean up refcounting in audit-treeMiklos Szeredi
Drop the initial reference by fsnotify_init_mark early instead of audit_tree_freeing_mark() at destroy time. In the cases we destroy the mark before we drop the initial reference we need to get rid of the get_mark that balances the put_mark in audit_tree_freeing_mark(). Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2012-08-15audit: fix refcounting in audit-treeMiklos Szeredi
Refcounting of fsnotify_mark in audit tree is broken. E.g: refcount create_chunk alloc_chunk 1 fsnotify_add_mark 2 untag_chunk fsnotify_get_mark 3 fsnotify_destroy_mark audit_tree_freeing_mark 2 fsnotify_put_mark 1 fsnotify_put_mark 0 via destroy_list fsnotify_mark_destroy -1 This was reported by various people as triggering Oops when stopping auditd. We could just remove the put_mark from audit_tree_freeing_mark() but that would break freeing via inode destruction. So this patch simply omits a put_mark after calling destroy_mark or adds a get_mark before. The additional get_mark is necessary where there's no other put_mark after fsnotify_destroy_mark() since it assumes that the caller is holding a reference (or the inode is keeping the mark pinned, not the case here AFAICS).

On a 2-node machine with 256GB of ram we get 512 lines of console output, which is just too much. This mimicks Yinghai Lu's x86 commit c2b91e2eec9678dbda274e906cc32ea8f711da3b (x86_64/mm: check and print vmemmap allocation continuous) except that we aren't ever going to get contiguous block pointers in between calls so just print when the virtual address or node changes.

The flow classifier can use uids and gids of the sockets that are transmitting packets and do insert those uids and gids into the packet classification calcuation. I don't fully understand the details but it appears that we can depend on specific uids and gids when making traffic classification decisions. To work with user namespaces enabled map from kuids and kgids into uids and gids in the initial user namespace giving raw integer values the code can play with and depend on. To avoid issues of userspace depending on uids and gids in packet classifiers installed from other user namespaces and getting confused deny all packet classifiers that use uids or gids that are not comming from a netlink socket in the initial user namespace.

cls_flow.c plays with uids and gids. Unless I misread that code it is possible for classifiers to depend on the specific uid and gid values.

In particular I want access to sk_user_ns(NETLINK_CB(in_skb).ssk).

At logging instance creation capture the peer netlink socket's user namespace. Use the captured peer user namespace when reporting socket uids to the peer. The peer socket's user namespace is guaranateed to be valid until the user closes the netlink socket. nfnetlink_log removes instances during the final close of a socket. __build_packet_message does not get called after an instance is destroyed.

2012-08-14netlink: Make the sending netlink socket availabe in NETLINK_CBEric W. Biederman
The sending socket of an skb is already available by it's port id in the NETLINK_CB. If you want to know more like to examine the credentials on the sending socket you have to look up the sending socket by it's port id and all of the needed functions and data structures are static inside of af_netlink.c. So do the simple thing and pass the sending socket to the receivers in the NETLINK_CB. I intend to use this to get the user namespace of the sending socket in inet_diag so that I can report uids in the context of the process who opened the socket, the same way I report uids in the contect of the process who opens files.

Correct a long standing omission and use struct pid in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_PROCESS. This guarantees we don't have issues when pid wraparound occurs. Use a kuid_t in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_USER to add user namespace support. In /proc/net/ip6_flowlabel capture the current pid namespace when opening the file and release the pid namespace when the file is closed ensuring we print the pid owner value that is meaning to the reader of the file. Similarly use from_kuid_munged to print uid values that are meaningful to the reader of the file. This requires exporting pid_nr_ns so that ipv6 can continue to built as a module.

2012-08-14userns: Make seq_file's user namespace accessibleEric W. Biederman
struct file already has a user namespace associated with it in file->f_cred->user_ns, unfortunately because struct seq_file has no struct file backpointer associated with it, it is difficult to get at the user namespace in seq_file context. Therefore add a helper function seq_user_ns to return the associated user namespace and a user_ns field to struct seq_file to be used in implementing seq_user_ns.
