Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>:

This series removes the currently-unused PRCM macros from
arch/arm/mach-omap2.

Basic test logs are available at:

http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/

Once, years ago, we thought that it would be good to document the PRCM
register bits in the Linux codebase.  Most folks in the broader
community did not have access to the same documentation, so we thought
that they might be able to use these bits to fix bugs and improve the
code.

We were also able to autogenerate most of these macros, so it was
thought that defining them in advance would reduce the risk of error,
inconsistencies, and merge conflicts caused when patch sets
incrementally defined them by hand.

Well, nice thoughts.  But the first rationale was rendered partially
obsolete when TI started to release public TRM documentation PDFs at
some point in the OMAP3 timeframe.  (Despite their weaknesses, TI's
public OMAP TRMs remain the most useful public documentation available
for any ARM Linux SoC -- at least to the extent of my knowledge.)  And
then the current Linux development tropism towards
development-by-negative-diffstat obliterated the remainder of the
above two philosophies.

So, for the few, the masochistic, out there who wish to continue
developing TI PRCM code, I would ask that you resurrect any
additionally-needed macros from these commits, rather than writing
them manually.  Purely for the sake of a pleasant atavism, perhaps; the
way one appreciates a used bookstore, or a video rental store...

And thanks to the upstream maintainers for being patient while we
adjust.

11 years agonetlabel: use domain based selectors when address based selectors are not available

netlabel: use domain based selectors when address based selectors are not available

NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both.  Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.

Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket.  The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors.  This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.

In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def.  This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.

net: check net.core.somaxconn sysctl values

It's possible to assign an invalid value to the net.core.somaxconn
sysctl variable, because there is no checks at all.

The sk_max_ack_backlog field of the sock structure is defined as
unsigned short. Therefore, the backlog argument in inet_listen()
shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
is truncated to the somaxconn value. So, the somaxconn value shouldn't
exceed 65535 (USHRT_MAX).
Also, negative values of somaxconn are meaningless.

before:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
net.core.somaxconn = 65536

---[ end trace b02321f40e4269a3 ]---

We have the following call chain:

tipc_core_start()
    ret = tipc_subscr_start()
        ret = tipc_server_start(){
                  server->enabled = 1;
                  ret = tipc_open_listening_sock()
              }

I.e., the server->enabled flag is unconditionally set to 1, whatever
the return value of tipc_open_listening_sock().

This causes a crash when tipc_core_start() tries to clean up
resources after a failed initialization:

    if (ret == failed)
        tipc_subscr_stop()
            tipc_server_stop(){
                if (server->enabled)
                    tipc_close_conn(){
                        NULL reference of con->sock-sk
                        OOPS!
                }
            }

To avoid this, tipc_server_start() should only set server->enabled
to 1 in case of a succesful socket creation. In case of failure, it
should release all allocated resources before returning.

Problem introduced in commit c5fa7b3cf3cb22e4ac60485fc2dc187fe012910f
("tipc: introduce new TIPC server infrastructure") in v3.11-rc1.
Note that it won't be seen often; it takes a module load under memory
constrained conditions in order to trigger the failure condition.

11 years agoipv6: prevent race between address creation and removal
Jiri Benc [Thu, 1 Aug 2013 08:41:28 +0000 (10:41 +0200)]
ipv6: prevent race between address creation and removal

There's a race in IPv6 automatic addess assignment. The address is created
with zero lifetime when it's added to various address lists. Before it gets
assigned the correct lifetime, there's a window where a new address may be
configured. This causes the semi-initiated address to be deleted in
addrconf_verify.

This was discovered as a reference leak caused by concurrent run of
__ipv6_ifa_notify for both RTM_NEWADDR and RTM_DELADDR with the same
address.

Fix this by setting the lifetime before the address is added to
inet6_addr_lst.

A few notes:

1. In addrconf_prefix_rcv, by setting update_lft to zero, the
   if (update_lft) { ... } condition is no longer executed for newly
   created addresses. This is okay, as the ifp fields are set in
   ipv6_add_addr now and ipv6_ifa_notify is called (and has been called)
   through addrconf_dad_start.

2. The removal of the whole block under ifp->lock in inet6_addr_add is okay,
   too, as tstamp is initialized to jiffies in ipv6_add_addr.
