2013-08-26cgroup: implement CFTYPE_NO_PREFIXTejun Heo
When cgroup files are created, cgroup core automatically prepends the name of the subsystem as prefix. This patch adds CFTYPE_NO_ which disables the automatic prefix. This is to work around historical baggages and shouldn't be used for new files. This will be used to move "cgroup.event_control" from cgroup core to memcg.

2013-08-26cgroup: rename cgroup_css_from_dir() to css_from_dir() and update its syntaxTejun Heo
cgroup_css_from_dir() will grow another user. In preparation, make the following changes. * All css functions are prefixed with just "css_", rename it to css_from_dir(). * Take dentry * instead of file * as dentry is what ultimately identifies a cgroup and file may not always be available. Note that the function now checkes whether @dentry->d_inode is NULL as the caller now may specify a negative dentry. * Make it take cgroup_subsys * instead of integer subsys_id. This simplifies the function and allows specifying no subsystem for cgroup->dummy_css. * Make return section a bit less verbose. This patch doesn't introduce any behavior changes.

2013-08-26openvswitch: Add SCTP supportJoe Stringer
This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.

2013-08-26HID: hidraw: Add spinlock in struct hidraw to protect listYonghua Zheng
It is unsafe to call list_for_each_entry in hidraw_report_event to traverse each hidraw_list node without a lock protection, the list could be modified if someone calls hidraw_release and list_del to remove itself from the list, this can cause hidraw_report_event to touch a deleted list struct and panic.

2013-08-26fs/9p: avoid accessing utsname after namespace has been torn downWill Deacon
During trinity fuzzing in a kvmtool guest, I stumbled across the following: Unable to handle kernel NULL pointer dereference at virtual address 00000004 PC is at v9fs_file_do_lock+0xc8/0x1a0 LR is at v9fs_file_do_lock+0x48/0x1a0 [<c01e2ed0>] (v9fs_file_do_lock+0xc8/0x1a0) from [<c0119154>] (locks_remove_flock+0x8c/0x124) [<c0119154>] (locks_remove_flock+0x8c/0x124) from [<c00d9bf0>] (__fput+0x58/0x1e4) [<c00d9bf0>] (__fput+0x58/0x1e4) from [<c0044340>] (task_work_run+0xac/0xe8) [<c0044340>] (task_work_run+0xac/0xe8) from [<c002e36c>] (do_exit+0x6bc/0x8d8) [<c002e36c>] (do_exit+0x6bc/0x8d8) from [<c002e674>] (do_group_exit+0x3c/0xb0) [<c002e674>] (do_group_exit+0x3c/0xb0) from [<c002e6f8>] (__wake_up_parent+0x0/0x18) I believe this is due to an attempt to access utsname()->nodename, after exit_task_namespaces() has been called, leaving current->nsproxy->uts_ns as NULL and causing the above dereference. A similar issue was fixed for lockd in 9a1b6bf818e7 ("LOCKD: Don't call utsname()->nodename from nlmclnt_setlockargs"), so this patch attempts something similar for 9pfs.

2013-08-26f2fs: reserve the xattr space dynamicallyJaegeuk Kim
This patch enables the number of direct pointers inside on-disk inode block to be changed dynamically according to the size of inline xattr space. The number of direct pointers, ADDRS_PER_INODE, can be changed only if the file has inline xattr flag. The number of direct pointers that will be used by inline xattrs is defined as F2FS_INLINE_XATTR_ADDRS. Current patch assigns F2FS_INLINE_XATTR_ADDRS to 0 temporarily.

2013-08-26xfrm: revert ipv4 mtu determination to dst_mtuHannes Frederic Sowa
In commit 0ea9d5e3e0e03a63b11392f5613378977dae7eca ("xfrm: introduce helper for safe determination of mtu") I switched the determination of ipv4 mtus from dst_mtu to ip_skb_dst_mtu. This was an error because in case of IP_PMTUDISC_PROBE we fall back to the interface mtu, which is never correct for ipv4 ipsec. This patch partly reverts 0ea9d5e3e0e03a63b11392f5613378977dae7eca ("xfrm: introduce helper for safe determination of mtu").

2013-08-24drm/msm: add a3xx gpu supportRob Clark
Add initial support for a3xx 3d core. So far, with hardware that I've seen to date, we can have: + zero, one, or two z180 2d cores + a3xx or a2xx 3d core, which share a common CP (the firmware for the CP seems to implement some different PM4 packet types but the basics of cmdstream submission are the same) Which means that the eventual complete "class" hierarchy, once support for all past and present hw is in place, becomes: + msm_gpu + adreno_gpu + a3xx_gpu + a2xx_gpu + z180_gpu This commit splits out the parts that will eventually be common between a2xx/a3xx into adreno_gpu, and the parts that are even common to z180 into msm_gpu. Note that there is no cmdstream validation required. All memory access from the GPU is via IOMMU/MMU. So as long as you don't map silly things to the GPU, there isn't much damage that the GPU can do.

2013-08-24cope with potentially long ->d_dname() output for shmem/hugetlbAl Viro
dynamic_dname() is both too much and too little for those - the output may be well in excess of 64 bytes dynamic_dname() assumes to be enough (thanks to ashmem feeding really long names to shmem_file_setup()) and vsnprintf() is an overkill for those guys.
