* fb: Use platform_data to retrieve tmiofb platform bitsSamuel Ortiz2011-05-262-8/+7
| | | | | | | | | | | With the addition of the platform device mfd_cell pointer, we can now cleanly pass the sub device drivers platform data pointers through the regular device platform_data one, and get rid of mfd_get_data().

* mfd: Use mfd cell platform_data for wl1273 cells platform bitsSamuel Ortiz2011-05-263-5/+6
| | | | | | | | | | | With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

* tmpfs: fix XATTR N overriding POSIX_ACL YEric Paris2011-05-261-14/+15
| | | | | | | | | | | | | Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL, even if it had been Y in oldconfig; and Linus reports that PulseAudio goes subtly wrong unless it can use ACLs on /dev/shm. Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS), and move the TMPFS_POSIX_ACL entry before the TMPFS_XATTR entry, to avoid asking unnecessary questions then ignoring their answers.

Not in the context of containers but in the context of people doing interesting things with routing. There is also demand in the context of containers to have an efficient way to execute some code in the container itself. If nothing else it is very useful ad a debugging technique. Both problems can be solved by starting some form of login daemon in the namespaces people want access to, or you can play games by ptracing a process and getting the traced process to do things you want it to do. However it turns out that a login daemon or a ptrace puppet controller are more code, they are more prone to failure, and generally they are less efficient than simply changing the namespace of a process to a specified one. Pieces of this puzzle can also be solved by instead of coming up with a general purpose system call coming up with targed system calls perhaps socketat that solve a subset of the larger problem. Overall that appears to be more work for less reward. int setns(int fd, int nstype); The fd argument is a file descriptor referring to a proc file of the namespace you want to switch the process to. In the setns system call the nstype is 0 or specifies an clone flag of the namespace you intend to change to prevent changing a namespace unintentionally. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W.

| * ns: proc files for namespace naming policy.Eric W. Biederman2011-05-106-11/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create files under /proc/<pid>/ns/ to allow controlling the namespaces of a process. This addresses three specific problems that can make namespaces hard to work with. - Namespaces require a dedicated process to pin them in memory. - It is not possible to use a namespace unless you are the child of the original creator. - Namespaces don't have names that userspace can use to talk about them. The namespace files under /proc/<pid>/ns/ can be opened and the file descriptor can be used to talk about a specific namespace, and to keep the specified namespace alive. A namespace can be kept alive by either holding the file descriptor open or bind mounting the file someplace else. aka: mount --bind /proc/self/ns/net /some/filesystem/path mount --bind /proc/self/fd/<N> /some/filesystem/path This allows namespaces to be named with userspace policy. It requires additional support to make use of these filedescriptors and that will be comming in the following patches. Acked-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: Eric W.

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an ASCONF chunk is outstanding, then the following ASCONF chunk will be queued for later transmission. But when we free the asoc, we forget to free the ASCONF queue at the same time, this will cause memory leak. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: David S.
