2013-09-18mailbox: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Acked-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2013-09-18ARM: OMAP4: Fix clock_get error for GPMC during bootTony Lindgren
Looks like we still have the legacy clock alias name for omap4 GPMC (General Purpose Memory Controller), so let's fix it for the device tree naming. There's no need to keep the legacy naming as omap4 is DT only nowadays. Without this fix we get the following error while booting: [ 0.440399] omap-gpmc 50000000.gpmc: error: clk_get Reported-by: Olof Johansson <olof@lixom.net> Cc: stable@vger.kernel.org # v3.11 Signed-off-by: Tony Lindgren <tony@atomide.com>

2013-09-18iio: at91: fix adc_clk overflowJosh Wu
The adc_clk variable is currently defined using a 32-bits unsigned integer, which will overflow under some very valid range of operations. Such overflow will occur if, for example, the parent clock is set to a 20MHz frequency and the ADC startup time is larger than 215ns. To fix this, introduce an intermediate variable holding the clock rate in kHz.

2013-09-18cnic: Fix crash in cnic_bnx2x_service_kcq()Michael Chan
commit 104a43edb264321a4d41850e98153b4fa8a9ef42 cnic: Use CHIP_NUM macros from bnx2x.h changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE is supported or not. There is another place in cnic that is still using the old method to determine if FCoE is supported or not. The 2 methods may not yield the same result after the network interface is brought down and up. This will cause the crash as cnic_bnx2x_service_kcq() will access the uninitialized cp->kcq2. The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code to remove the old method as it is no longer needed.

2013-09-18RPCSEC_GSS: fix crash on destroying gss authJ. Bruce Fields
This fixes a regression since eb6dc19d8e72ce3a957af5511d20c0db0a8bd007 "RPCSEC_GSS: Share all credential caches on a per-transport basis" which could cause an occasional oops in the nfsd code (see below). The problem was that an auth was left referencing a client that had been freed. To avoid this we need to ensure that auths are shared only between descendants of a common client; the fact that a clone of an rpc_client takes a reference on its parent then ensures that the parent client will last as long as the auth. Also add a comment explaining what I think was the intention of this code. general protection fault: 0000 [#1] PREEMPT SMP Modules linked in: rpcsec_gss_krb5 nfsd auth_rpcgss oid_registry nfs_acl lockd sunrpc CPU: 3 PID: 4071 Comm: kworker/u8:2 Not tainted 3.11.0-rc2-00182-g025145f #1665 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Workqueue: nfsd4_callbacks nfsd4_do_callback_rpc [nfsd] task: ffff88003e206080 ti: ffff88003c384000 task.ti: ffff88003c384000 RIP: 0010:[<ffffffffa00001f3>] [<ffffffffa00001f3>] rpc_net_ns+0x53/0x70 [sunrpc] RSP: 0000:ffff88003c385ab8 EFLAGS: 00010246 RAX: 6b6b6b6b6b6b6b6b RBX: ffff88003af9a800 RCX: 0000000000000002 RDX: ffffffffa00001a5 RSI: 0000000000000001 RDI: ffffffff81e284e0 RBP: ffff88003c385ad8 R08: 0000000000000001 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000015 R12: ffff88003c990840 R13: ffff88003c990878 R14: ffff88003c385ba8 R15: ffff88003e206080 FS: 0000000000000000(0000) GS:ffff88003fd80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007fcdf737e000 CR3: 000000003ad2b000 CR4: 00000000000006e0 Stack: ffffffffa00001a5 0000000000000006 0000000000000006 ffff88003af9a800 ffff88003c385b08 ffffffffa00d52a4 ffff88003c385ba8 ffff88003c751bd8 ffff88003c751bc0 ffff88003e113600 ffff88003c385b18 ffffffffa00d530c Call Trace: [<ffffffffa00001a5>] ? rpc_net_ns+0x5/0x70 [sunrpc] [<ffffffffa00d52a4>] __gss_pipe_release+0x54/0x90 [auth_rpcgss] [<ffffffffa00d530c>] gss_pipe_free+0x2c/0x30 [auth_rpcgss] [<ffffffffa00d678b>] gss_destroy+0x9b/0xf0 [auth_rpcgss] [<ffffffffa000de63>] rpcauth_release+0x23/0x30 [sunrpc] [<ffffffffa0001e81>] rpc_release_client+0x51/0xb0 [sunrpc] [<ffffffffa00020d5>] rpc_shutdown_client+0xe5/0x170 [sunrpc] [<ffffffff81098a14>] ? cpuacct_charge+0xa4/0xb0 [<ffffffff81098975>] ? cpuacct_charge+0x5/0xb0 [<ffffffffa019556f>] nfsd4_process_cb_update.isra.17+0x2f/0x210 [nfsd] [<ffffffff819a4ac0>] ? _raw_spin_unlock_irq+0x30/0x60 [<ffffffff819a4acb>] ? _raw_spin_unlock_irq+0x3b/0x60 [<ffffffff810703ab>] ? process_one_work+0x15b/0x510 [<ffffffffa01957dd>] nfsd4_do_callback_rpc+0x8d/0xa0 [nfsd] [<ffffffff8107041e>] process_one_work+0x1ce/0x510 [<ffffffff810703ab>] ? process_one_work+0x15b/0x510 [<ffffffff810712ab>] worker_thread+0x11b/0x370 [<ffffffff81071190>] ? manage_workers.isra.24+0x2b0/0x2b0 [<ffffffff8107854b>] kthread+0xdb/0xe0 [<ffffffff819a4ac0>] ? _raw_spin_unlock_irq+0x30/0x60 [<ffffffff81078470>] ? __init_kthread_worker+0x70/0x70 [<ffffffff819ac7dc>] ret_from_fork+0x7c/0xb0 [<ffffffff81078470>] ? __init_kthread_worker+0x70/0x70 Code: a5 01 00 a0 31 d2 31 f6 48 c7 c7 e0 84 e2 81 e8 f4 91 0a e1 48 8b 43 60 48 c7 c2 a5 01 00 a0 be 01 00 00 00 48 c7 c7 e0 84 e2 81 <48> 8b 98 10 07 00 00 e8 91 8f 0a e1 e8 +3c 4e 07 e1 48 83 c4 18 RIP [<ffffffffa00001f3>] rpc_net_ns+0x53/0x70 [sunrpc] RSP <ffff88003c385ab8> Signed-off-by: J.

Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c) removed legacy booting in favor of device tree based booting for pandaboard. That caused the WLAN to stop working as the related .dts entries fell through the cracks. The legacy muxing was setting pulls for GPIO 48 and 49, so let's keep that behaviour for now to avoid further regressions for BT and FM. Also input logic was enabled for MMC CLK line, but I've verified that the input logic we don't need enabled for CLK line as it's not bidirectional. Also, we want to use non-removable instead of ti,non-removable as the ti,non-removable also sets no_regulator_off_init which is really not what we want as then wl12xx won't get powered up and down which is needed for resetting it. Note that looks like the WLAN interface fails to come up after a warm reset, but that most likely was also happening with the legacy booting and needs a separate fix.

2013-09-17tty: disassociate_ctty() sends the extra SIGCONTOleg Nesterov
Starting from v3.10 (probably commit f91e2590410b: "tty: Signal foreground group processes in hangup") disassociate_ctty() sends SIGCONT if tty && on_exit. This breaks LSB test-suite, in particular test8 in _exit.c and test40 in sigcon5.c. Put the "!on_exit" check back to restore the old behaviour. Review by Peter Hurley: "Yes, this regression was introduced by me in that commit. The effect of the regression is that ptys will receive a SIGCONT when, in similar circumstances, ttys would not. The fact that two test vectors accidentally tripped over this regression suggests that some other apps may as well.

2013-09-17vxlan: Avoid creating fdb entry with NULL destinationSridhar Samudrala
Commit afbd8bae9c798c5cdbe4439d3a50536b5438247c vxlan: add implicit fdb entry for default destination creates an implicit fdb entry for default destination. This results in an invalid fdb entry if default destination is not specified. For ex: ip link add vxlan1 type vxlan id 100 creates the following fdb entry 00:00:00:00:00:00 dev vxlan1 dst 0.0.0.0 self permanent This patch fixes this issue by creating an fdb entry only if a valid default destination is specified.

2013-09-17net loopback: Set loopback_dev to NULL when freedEric W. Biederman
It has recently turned up that we have a number of long standing bugs in the network stack cleanup code with use of the loopback device after it has been freed that have not turned up because in most cases the storage allocated to the loopback device is not reused, when those accesses happen. Set looback_dev to NULL to trigger oopses instead of silent data corrupt when we hit this class of bug. Signed-off-by: "Eric W.

2013-09-18cpufreq: unlock correct rwsem while updating policy->cpuViresh Kumar
Current code looks like this: WARN_ON(lock_policy_rwsem_write(cpu)); update_policy_cpu(policy, new_cpu); unlock_policy_rwsem_write(cpu); {lock|unlock}_policy_rwsem_write(cpu) takes/releases policy->cpu's rwsem. Because cpu is changing with the call to update_policy_cpu(), the unlock_policy_rwsem_write() will release the incorrect lock. The right solution would be to release the same lock as was taken earlier. Also update_policy_cpu() was also called from cpufreq_add_dev() without any locks and so its better if we move this locking to inside update_policy_cpu(). This patch fixes a regression introduced in 3.12 by commit f9ba680d23 (cpufreq: Extract the handover of policy cpu to a helper function).

2013-09-18cpufreq: Clear policy->cpus bits in __cpufreq_remove_dev_finish()Viresh Kumar
This broke after a recent change "cedb70a cpufreq: Split __cpufreq_remove_dev() into two parts" from Srivatsa. Consider a scenario where we have two CPUs in a policy (0 & 1) and we are removing CPU 1. On the call to __cpufreq_remove_dev_prepare() we have cleared 1 from policy->cpus and now on a call to __cpufreq_remove_dev_finish() we read cpumask_weight of policy->cpus, which will come as 1 and this code will behave as if we are removing the last CPU from policy :) Fix it by clearing the CPU mask in __cpufreq_remove_dev_finish() instead of __cpufreq_remove_dev_prepare().

When receiving or sending a packet a packet on a VLAN, the vid has to be marked with the TAG flag in order to make any component in batman-adv understand that the packet is coming from a really tagged network.
