Bug symptoms ~~~~~~~~~~~~ For the same inode VFS calls read_inode() twice and doesn't call clear_inode() between the two read_inode() invocations. Bug description ~~~~~~~~~~~~~~~ Suppose we have an inode which has zero reference count but is still in the inode cache. Suppose kswapd invokes shrink_icache_memory() to free some RAM. In prune_icache() inodes are removed from i_hash. prune_icache () is then going to call clear_inode(), but drops the inode_lock spinlock before this. If in this moment another task calls iget() for an inode which was just removed from i_hash by prune_icache(), then iget() invokes read_inode() for this inode, because it is *already removed* from i_hash. The end result is: we call iget(#N) then iput(#N); inode #N has zero i_count now and is in the inode cache; kswapd starts. kswapd removes the inode #N from i_hash ans is preempted; we call iget(#N) again; read_inode() is invoked as the result; but we expect clear_inode() before. Fix ~~~~~~~ To fix the bug I remove inodes from i_hash later, when clear_inode() is actually called. I remove them from i_hash under spinlock protection. Since the i_state is set to I_FREEING, it is safe to do this. The others will sleep waiting for the inode state change. I also postpone removing inodes from i_sb_list. It is not compulsory to do so but I do it for readability reasons. Inodes are added/removed to the lists together everywhere in the code and there is no point to change this rule. This is harmless because the only user of i_sb_list which somehow may interfere with me (invalidate_list()) is excluded by the iprune_sem mutex. The same race is possible in invalidate_list() so I do the same for it.

This patch fixes queer behavior in __wait_on_freeing_inode(). If I_LOCK was not set it called yield(), effectively busy waiting for the removal of the inode from the hash. This change was introduced within "[PATCH] eliminate inode waitqueue hashtable" Changeset 1.1938.166.16 last october by wli. The solution is to restore the old behavior, of unconditionally waiting on the waitqueue. It doesn't matter if I_LOCK is not set initally, the task will go to sleep, and wake up when wake_up_inode() is called from generic_delete_inode() after removing the inode from the hash chain. Comment is also updated to better reflect current behavior. This condition is very hard to trigger normally (simultaneous clear_inode() with iget()) so probably only heavy stress testing can reveal any change of behavior.

OK, I can see what's happening here. eth0 doesn't detect link-up until after a few seconds, so when the vlan interface is opened immediately after eth0 has been opened, it inherits the link-down state. Subsequently the vlan interface is never properly activated and are thus unable to transmit any packets. dev->state bits are not supposed to be manipulated directly. Something similar is probably needed for the netif_device_present() bit, although I don't know how this is meant to work for a virtual device. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The following driver provides complete interrupt-in and interrupt-out reports (raw data) to a user program. Until now it uses the HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it will be ok for you - and I will be happy, if you assign 8 minor numbers. I have tested it in several environments and it works very well for me. However, it has a problem with two or more devices at the same hub, if the two or more devices need 1 ms interrupt-in transfers. Unfortunately more than one interrupt-in transfer every ms isn't possible (ehci driver?). This is why the min_interrupt_in_interval and min_interrupt_out_interval are increased to 2 ms (see the corresponding module parameters). This way, I can use two devices simultaneously at the same hub. Signed-off-by: NMichael Hund <mhund@ld-didactic.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The recent "pm_message_t" changes removed functionality from the Linux PM framework. This patch removes it from the OMAP OHCI too, removing the distinction between (previous) PM_SUSPEND_MEM and PM_SUSPEND_DISK state transitions ... now the only suspend semantics supportable are what was previously PM_SUSPEND_DISK (4) and is now "PMSG_SUSPEND" (3).

This driver is a basic keypress input driver for the Keyspan Digital Remote with part number UIA-11. Currently there is an older remote with part number UIA-10 which isn't supported by this driver. Support for the older UIA-10 could be added but a binary file is required to be download to the device, and I don't have that file. I also don't have a UIA-10 device so I wouldn't be able to test any of the changes. Signed-off-by: NMichael Downey <downey@zymeta.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Make usbmon to print Setup packets of Control transfers. This is useful when debugging enumeration issues. This is a change to the trace format which is not fully compatible. A parser has to look at the data length word now. If that word is a character like 's', read setup packet before proceeding with data. I decided not to bump the API tag for this because not many such parsers exist at this point. Signed-off-by: NPete Zaitcev <zaitcev@redhat.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

We map states 0x00 and 0x10 to the ATM_PHY_SIG_LOST flag. The current logic fails to resync the line if we get state 0x10 followed by 0x00, since we only resync the line when the state is 0x00 and the flag changed. Doubly fixed by (1) always resyncing the line when the state is 0x00 even if the state didn't change, and (2) keeping track of the last state, not just the flag. We do (2) as well as (1) in order to get better log messages. This is a tweaked version of the original patch by Aurelio Arroyo.
