2011-08-25md: use REQ_NOIDLE flag in md_super_write()Namhyung Kim1-1/+1
Queue idling is used for the anticipation of immediate sequencial I/O's but md_super_write() is a kind of one- shot operation, coupled with md_super_wait(), so the idling in this case will be just a waste of time. Specifying REQ_NOIDLE prevents it. Instead of adding the flag to submit_bio() directly, use pre-defined macro WRITE_FLUSH_FUA.

2011-08-25md: ensure changes to 'write-mostly' are reflected in metadata.NeilBrown1-0/+5
The 'write-mostly' flag can be changed through sysfs. With 0.90 metadata, those changes are reflected in the metadata. For 1.x metadata, they aren't. So fix super_1_sync to record 'write-mostly' status. Signed-off-by: NeilBrown <[email protected]>
2011-08-25md: report failure if a 'set faulty' request doesn't.NeilBrown1-1/+6
Sometimes a device will refuse to be set faulty. e.g. RAID1 will never let the last working device become faulty. So check if "md_error()" did manage to set the faulty flag and fail with EBUSY if it didn't.

2011-08-24sendmmsg/sendmsg: fix unsafe user pointer accessMathieu Desnoyers1-4/+6
Dereferencing a user pointer directly from kernel-space without going through the copy_from_user family of functions is a bad idea. Two of such usages can be found in the sendmsg code path called from sendmmsg, added by commit c71d8ebe7a4496fb7231151cb70a6baa0cb56f9a upstream. commit 5b47b8038f183b44d2d8ff1c7d11a5c1be706b34 in the 3.0-stable tree. Usages are performed through memcmp() and memcpy() directly. Fix those by using the already copied msg_sys structure instead of the __user *msg structure. Note that msg_sys can be set to NULL by verify_compat_iovec() or verify_iovec(), which requires additional NULL pointer checks.

2011-08-24arp: fix rcu lockdep splat in arp_process()Eric Dumazet1-2/+6
Dave Jones reported a lockdep splat triggered by an arp_process() call from parp_redo(). Commit faa9dcf793be (arp: RCU changes) is the origin of the bug, since it assumed arp_process() was called under rcu_read_lock(), which is not true in this particular path. Instead of adding rcu_read_lock() in parp_redo(), I chose to add it in neigh_proxy_process() to take care of IPv6 side too. =================================================== [ INFO: suspicious rcu_dereference_check() usage. ] --------------------------------------------------- include/linux/inetdevice.h:209 invoked rcu_dereference_check() without protection! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 0 4 locks held by setfiles/2123: #0: (&sb->s_type->i_mutex_key#13){+.+.+.}, at: [<ffffffff8114cbc4>] walk_component+0x1ef/0x3e8 #1: (&isec->lock){+.+.+.}, at: [<ffffffff81204bca>] inode_doinit_with_dentry+0x3f/0x41f #2: (&tbl->proxy_timer){+.-...}, at: [<ffffffff8106a803>] run_timer_softirq+0x157/0x372 #3: (class){+.-...}, at: [<ffffffff8141f256>] neigh_proxy_process +0x36/0x103 stack backtrace: Pid: 2123, comm: setfiles Tainted: G W 3.1.0-0.rc2.git7.2.fc16.x86_64 #1 Call Trace: <IRQ> [<ffffffff8108ca23>] lockdep_rcu_dereference+0xa7/0xaf [<ffffffff8146a0b7>] __in_dev_get_rcu+0x55/0x5d [<ffffffff8146a751>] arp_process+0x25/0x4d7 [<ffffffff8146ac11>] parp_redo+0xe/0x10 [<ffffffff8141f2ba>] neigh_proxy_process+0x9a/0x103 [<ffffffff8106a8c4>] run_timer_softirq+0x218/0x372 [<ffffffff8106a803>] ? run_timer_softirq+0x157/0x372 [<ffffffff8141f220>] ? neigh_stat_seq_open+0x41/0x41 [<ffffffff8108f2f0>] ? mark_held_locks+0x6d/0x95 [<ffffffff81062bb6>] __do_softirq+0x112/0x25a [<ffffffff8150d27c>] call_softirq+0x1c/0x30 [<ffffffff81010bf5>] do_softirq+0x4b/0xa2 [<ffffffff81062f65>] irq_exit+0x5d/0xcf [<ffffffff8150dc11>] smp_apic_timer_interrupt+0x7c/0x8a [<ffffffff8150baf3>] apic_timer_interrupt+0x73/0x80 <EOI> [<ffffffff8108f439>] ? trace_hardirqs_on_caller+0x121/0x158 [<ffffffff814fc285>] ? __slab_free+0x30/0x24c [<ffffffff814fc283>] ? __slab_free+0x2e/0x24c [<ffffffff81204e74>] ? inode_doinit_with_dentry+0x2e9/0x41f [<ffffffff81204e74>] ? inode_doinit_with_dentry+0x2e9/0x41f [<ffffffff81204e74>] ? inode_doinit_with_dentry+0x2e9/0x41f [<ffffffff81130cb0>] kfree+0x108/0x131 [<ffffffff81204e74>] inode_doinit_with_dentry+0x2e9/0x41f [<ffffffff81204fc6>] selinux_d_instantiate+0x1c/0x1e [<ffffffff81200f4f>] security_d_instantiate+0x21/0x23 [<ffffffff81154625>] d_instantiate+0x5c/0x61 [<ffffffff811563ca>] d_splice_alias+0xbc/0xd2 [<ffffffff811b17ff>] ext4_lookup+0xba/0xeb [<ffffffff8114bf1e>] d_alloc_and_lookup+0x45/0x6b [<ffffffff8114cbea>] walk_component+0x215/0x3e8 [<ffffffff8114cdf8>] lookup_last+0x3b/0x3d [<ffffffff8114daf3>] path_lookupat+0x82/0x2af [<ffffffff8110fc53>] ? might_fault+0xa5/0xac [<ffffffff8110fc0a>] ? might_fault+0x5c/0xac [<ffffffff8114c564>] ? getname_flags+0x31/0x1ca [<ffffffff8114dd48>] do_path_lookup+0x28/0x97 [<ffffffff8114df2c>] user_path_at+0x59/0x96 [<ffffffff811467ad>] ? cp_new_stat+0xf7/0x10d [<ffffffff811469a6>] vfs_fstatat+0x44/0x6e [<ffffffff811469ee>] vfs_lstat+0x1e/0x20 [<ffffffff81146b3d>] sys_newlstat+0x1a/0x33 [<ffffffff8108f439>] ? trace_hardirqs_on_caller+0x121/0x158 [<ffffffff812535fe>] ? trace_hardirqs_on_thunk+0x3a/0x3f [<ffffffff8150af82>] system_call_fastpath+0x16/0x1b Reported-by: Dave Jones <[email protected]> Signed-off-by: Eric Dumazet <[email protected]> Signed-off-by: David S.

2011-08-24firmware loader: allow builtin firmware load even if usermodehelper is disabledLinus Torvalds1-5/+6
In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware.

2011-08-24ARM: mach-shmobile: sh7372 LCDC1 suspend fixMagnus Damm3-0/+4
Associate the HDMI clock together with LCDC1 on sh7372. Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.

2011-08-24ASoC: Tegra: wm8903 machine driver: Drop Ventana supportStephen Warren1-2/+2
Board file support for Ventana is not yet mainlined, and probably won't ever be given the move to Device-Tree. Consequently, the Ventana entry is being removed from arch/arm/tools/mach-types in the next merge window, since it was registered over a year ago. This will also remove function machine_is_ventana(), which is used by the ASoC Tegra WM8903 machine driver. This will cause compilation failures. Drop Ventana support to resolve this. Hopefully, in the not-too-distant future, tegra_wm8903.c will be able to configure itself from Device-Tree, and hence we'll be able to re-instate Ventana support just by creating a .dts file for the board. Also note that Aebl support is in a similar boat. However, that board isn't scheduled for deprecation for at least another 5 months, and perhaps we will have completely removed non-Device-Tree support from tegra_wm8903.c by then and/or adjusted mach-types policy.

When we enter a 32-bit system call via SYSENTER or SYSCALL, we shuffle the arguments to match the int $0x80 calling convention. This was probably a design mistake, but it's what it is now. This causes errors if the system call as to be restarted. For SYSENTER, we have to invoke the instruction from the vdso as the return address is hardcoded. Accordingly, we can simply replace the jump in the vdso with an int $0x80 instruction and use the slower entry point for a post-restart.

2011-08-23staging: zcache: fix crash on high memory swapSeth Jennings1-4/+4
zcache_put_page() was modified to pass page_address(page) instead of the actual page structure. In combination with the function signature changes to tmem_put() and zcache_pampd_create(), zcache_pampd_create() tries to (re)derive the page structure from the virtual address. However, if the original page is a high memory page (or any unmapped page), this virt_to_page() fails because the page_address() in zcache_put_page() returned NULL. This patch changes zcache_put_page() and zcache_get_page() to pass the page structure instead of the page's virtual address, which may or may not exist.

2011-08-23wl12xx: add max_sched_scan_ssids value to the hw descriptionLuciano Coelho1-0/+1
After commit 5a865ba, we require a separate value to indicate the number of supported SSIDs in scheduled scans. This patch adds a proper value to the wl12xx driver. This fixes a regression in 3.1-rc3 where scheduled scans were not working properly with the wl12xx driver. Signed-off-by: Luciano Coelho <[email protected]> Signed-off-by: John W.

2011-08-23wl12xx: Fix validation of pm_runtime_get_sync return valueIdo Yariv1-1/+1
wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync is non-zero, and if so bails out. However, pm_runtime_get_sync can return a positive number which does not suggest an error has occurred. This is problematic for two reasons: 1. The function will needlessly bail out without decrementing back the runtime PM reference counter. 2. wl1271_power_on only checks if wl1271_power_on return value is negative. This means that wl1271_power_on will continue even if wl1271_sdio_power_on bailed out. As a result, sdio transactions will be initiated without properly enabling the sdio function and claiming the host. This could even lead to a kernel panic. Fix this by only checking that the return value of pm_runtime_get_sync is non-negative.

2011-08-23wl12xx: Remove obsolete testmode NVS push commandIdo Yariv1-45/+0
The testmode NVS push command is no longer in use. In addition, it has several implementation issues that prevent it from working correctly: 1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However, since the device was not necessarily booted by the time the function is called, wl->chip.id will be initialized to 0. 2. The NVS file is fetched by calling request_firmware() before it is possible to push an NVS file. 3. The maximum allowed size of nl binary payloads is not sufficient for pushing NVS files. 4. Pushing 128x NVS files will always fail due to a bug in the validation code. 5. In case the pushed NVS file is found invalid, the mutex will be kept locked and the nvs member will become a dangling pointer. Since this feature is not being used, remove it completely instead of fixing it. Signed-off-by: Ido Yariv <[email protected]> Acked-by: Luciano Coelho <[email protected]> Signed-off-by: John W.
