2009-10-07rcu: Move rcu_barrier() to rcutreePaul E. McKenney2-119/+120
Move the existing rcu_barrier() implementation to rcutree.c, consistent with the fact that the rcu_barrier() implementation is tied quite tightly to the RCU implementation. This opens the way to simplify and fix rcutree.c's rcu_barrier() implementation in a later patch. Signed-off-by: Paul E.

Clear out pending command that got rejected with 'ERROR' response.

2009-10-06gigaset: linearize skbTilman Schmidt1-0/+6
The code of the Gigaset driver assumes that sk_buff-s coming from the ISDN4Linux subsystem are always linear. Explicitly calling skb_linearize() is cheap if they are, but much more robust in case they ever aren't.

2009-10-06isdn: avoid races in capidrvTilman Schmidt1-12/+13
In several places, capidrv sends a CAPI message to the ISDN device and then updates its internal state accordingly. If the response message from the device arrives before the state is updated, it may be rejected or processed incorrectly. Avoid these races by updating the state before emitting the message.

2009-10-06isdn: accept CAPI Informational Info values as successTilman Schmidt1-1/+1
Info values in the 0x00xx range are defined in the CAPI standard as "Informational, message processed successfully". Therefore a CONNECT_B3_CONF message with an Info value in that range should open an NCCI just as with Info==0.

2009-10-06libata: fix incorrect link online check during probeTejun Heo1-18/+32
While trying to work around spurious detection retries for non-existent devices on slave links, commit 816ab89782ac139a8b65147cca990822bb7e8675 incorrectly added link offline check logic before ata_eh_thaw() was called. This means that if an occupied link goes down briefly at the time that offline check was performed, device class will be cleared to ATA_DEV_NONE and libata wouldn't retry thus failing detection of the device. The offline check should be done after the port is thawed together with online check so that such link glitches can be detected by the interrupt handler and handled properly.

2009-10-06be2net: Bug fix to properly update ethtool tx-checksumming after ethtool -K ↵Ajit Khaparde2-3/+3
<ifname> tx off This is a fix for a bug which was a result of wrong use of checksum offload flag. The status of tx-checksumming was not changed from on to off after a 'ethtool -K <ifname> tx off' operation. Use the proper checksum offload flag NETIF_F_HW_CSUM instead of NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM. Patch is against net-2.6 tree.

2009-10-06qlge: Fix lock/mutex warnings.Ron Mercer4-17/+9

2009-10-06NFSv4: Fix the referral mount codeTrond Myklebust1-6/+6
Fix a typo which causes try_location() to use the wrong length argument when calling nfs_parse_server_name(). This again, causes the initialisation of the mount's sockaddr structure to fail. Also ensure that if nfs4_pathname_string() returns an error, then we pass that error back up the stack instead of ENOENT. Signed-off-by: Trond Myklebust <[email protected]>
2009-10-06nfs: Avoid overrun when copying client IP address stringBen Hutchings1-1/+1
As seen in <http://bugs.debian.org/549002>, nfs4_init_client() can overrun the source string when copying the client IP address from nfs_parsed_mount_data::client_address to nfs_client::cl_ipaddr. Since these are both treated as null-terminated strings elsewhere, the copy should be done with strlcpy() not memcpy().

2009-10-06NFS: Fix port initialisation in nfs_remount()Trond Myklebust1-2/+4
The recent changeset 53a0b9c4c99ab0085a06421f71592722e5b3fd5f (NFS: Replace nfs_parse_ip_address() with rpc_pton()) broke nfs_remount, since the call to rpc_pton() will zero out the port number in data->nfs_server.address. This is actually due to a bug in nfs_remount: it should be looking at the port number in nfs_server.port instead...

2009-10-06NFS: Fix port and mountport display in /proc/self/mountinfoTrond Myklebust1-9/+7

2009-10-06NFS: Fix a default mount regression...Trond Myklebust1-7/+6
With the recent spate of changes, the nfs protocol version will now default to 2 instead of 3, while the mount protocol version defaults to 3. The following patch should ensure the defaults are consistent with the previous defaults of vers=3,proto=tcp,mountvers=3,mountproto=tcp.

This fixes a bug introduced by this commit ID: commit 537a1bf059fa312355696fa6db80726e655e7f17 Author: Krzysztof Helt <[email protected]> Date: Tue Jun 30 11:41:29 2009 -0700 fbdev: add mutex for fb_mmap locking In which a mutex was added when changing smem_start and smem_len fields, so the mutex inside the fb_mmap() call is actually used. The problem was that set_fb_fix, which modifies the above 2 fields, was called before and after registering the framebuffer, which when used before registration, lead to a failed attempt to use an uninitialized mutex.

2009-10-06futex: Nullify robust lists after cleanupPeter Zijlstra1-2/+6
The robust list pointers of user space held futexes are kept intact over an exec() call. When the exec'ed task exits exit_robust_list() is called with the stale pointer. The risk of corruption is minimal, but still it is incorrect to keep the pointers valid. Actually glibc should uninstall the robust list before calling exec() but we have to deal with it anyway. Nullify the pointers after [compat_]exit_robust_list() has been called.

2009-10-06sound: via82xx: move DXS volume controls to PCM interfaceClemens Ladisch1-9/+18
The "VIA DXS" controls are actually volume controls that apply to the four PCM substreams, so we better indicate this connection by moving the controls to the PCM interface. Commit b452e08e73c0e3dbb0be82130217be4b7084299e in 2.6.30 broke the restoring of these volumes by "alsactl restore" that most distributions use; the renaming in this patch cures that regression by preventing alsactl from applying the old, wrong volume levels to the new controls. http://bugzilla.kernel.org/show_bug.cgi?id=14151 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532613 Signed-off-by: Clemens Ladisch <[email protected]> Cc: <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
2009-10-06trace: Fix missing assignment in trace_ctxwake_*Hiroshi Shimamoto1-2/+2
The state char variable S should be reassigned, if S == 0. We are missing the state of the task that is going to sleep for the context switch events (in the raw mode). Fortunately the problem arises with the sched_switch/wake_up tracers, not the sched trace events. The formers are legacy now. But still, that was buggy.

2009-10-06perf_event: Provide vmalloc() based mmap() backingPeter Zijlstra5-62/+214
Some architectures such as Sparc, ARM and MIPS (basically everything with flush_dcache_page()) need to deal with dcache aliases by carefully placing pages in both kernel and user maps. These architectures typically have to use vmalloc_user() for this. However, on other architectures, vmalloc() is not needed and has the downsides of being more restricted and slower than regular allocations.
