GFS2 uses i_mutex on its system quota inode to synchronize writes to quota file. Since this is an internal inode to GFS2 (not part of directory hiearchy or visible by user) we are safe to define locking rules for it. So let's just get it its own locking class to make it clear.

This patch stops multiple block allocations if a nonzero return code is received from gfs2_rbm_from_block. Without this patch, if enough pressure is put on the file system, you get a kernel warning quickly followed by: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffffa04f47e8>] gfs2_alloc_blocks+0x2c8/0x880 [gfs2] With this patch, things run normally.

When rgd->rd_free_clone is less than rgd->rd_reserved, the unclaimed_blocks() calculation would wrap and produce incorrect results. This patch checks for this condition when this function is called from gfs2_mblk_search() In addition, the use of this particular function in other places in the code has been dropped by means of a general clean up of gfs2_inplace_reserve(). This function is now much easier to follow. Also the setting of the rgd->rd_last_alloc field is corrected. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

This patch improves the tracing of block reservations by removing some corner cases and also providing more useful detail in the traces. A new field is added to the reservation structure to contain the inode number. This is used since in certain contexts it is not possible to access the inode itself to obtain this information. As a result we can then display the inode number for all tracepoints and also in case we dump the resource group. The "del" tracepoint operation has been removed. This could be called with the reservation rgrp set to NULL. That resulted in not printing the device number, and thus making the information largely useless anyway. Also, the conditional on the rgrp being NULL can then be removed from the tracepoint. After this change, all the block reservation tracepoint calls will be called with the rgrp information. The existing ins,clm and tdel calls to the block reservation tracepoint are sufficient to track the entire life of the block reservation. In gfs2_block_alloc() the error detection is updated to print out the inode number of the problematic inode. This can then be compared against the information in the glock dump,tracepoints, etc. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

When we get to the stage of allocating blocks, we know that the resource group in question must contain enough free blocks, otherwise gfs2_inplace_reserve() would have failed. So if we are left with only free blocks which are reserved, then we must use those. This can happen if another node has sneeked in and use some blocks reserved on this node, for example. Generally this will happen very rarely and only when the resouce group is nearly full. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

This patch fixes a few small rbm related things. First, it fixes a corner case where the rbm needs to switch bitmaps and wasn't adjusting its buffer pointer. Second, there's a white space issue fixed. Third, the logic in function gfs2_rbm_from_block was optimized a bit. Lastly, a check for goal block overflows was added to function gfs2_alloc_blocks.

This is part of a series of patches which are introducing the gfs2_rbm structure throughout the block allocation code. The main aim of this part is to create a search function which can deal directly with struct gfs2_rbm. In this case it specifies the initial position at which to start the search and also the point at which the search terminates. The net result of this is to clean up the search code and make it rather more readable, and the various possible exceptions which may occur during the search are partitioned into their own functions. There are some bug fixes too. We should not be checking the reservations while allocating extents - the time for that is when we are searching for where to put the extent, not when we've already made that decision. Also, rgblk_search had two uses, and in only one of those cases did it make sense to check for reservations. This is fixed in the new gfs2_rbm_find function, which has a cleaner interface. The reservation checking has been improved by always checking for contiguous reservations, and returning the first free block after all contiguous reservations. This is done under the spin lock to ensure consistancy of the tree. The allocation of extents is now in all cases done by the existing allocation code, and if there is an active reservation, that is updated after the fact. Again this is done under the spin lock, since it entails changing the lookup key for the reservation in question. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

This patch introduces a new structure, gfs2_rbm, which is a tuple of a resource group, a bitmap within the resource group and an offset within that bitmap. This is designed to make manipulating these sets of variables easier. There is also a new helper function which converts this representation back to a disk block address. In addition, the rbtree nodes which are used for the reservations were not being correctly initialised, which is now fixed. Also, the tracing was not passing through the inode where it should have been. That is mostly fixed aside from one corner case. This needs to be revisited since there can also be a NULL rgrp in some cases which results in the device being incorrect in the trace. This is intended to be the first step towards cleaning up some of the allocation code, and some further bug fixes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

The rs_requested field is left over from the original allocation code, however this should have been a parameter passed to the various functions from gfs2_inplace_reserve() and not a member of the reservation structure as the value is not required after the initial allocation. This also helps simplify the code since we no longer need to set the rs_requested to zero. Also the gfs2_inplace_release() function can also be simplified since the reservation structure will always be defined when it is called, and the only remaining task is to unlock the rgrp if required. It can also now be called unconditionally too, resulting in a further simplification. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

There were two functions in the xattr code which were nearly identical, the only difference being that one was copy data into the unstuffed xattrs and the other was copying data out from it.

Fix potential NULL pointer dereference in edac_unregister_sysfs() on system boot introduced in 3.6-rc1. Since commit 7a623c03 ("edac: rewrite the sysfs code to use struct device") edac_mc_alloc() no longer initializes embedded kobjects in struct mem_ctl_info. Therefore edac_mc_free() can no longer simply decrement a kobject reference count to free the allocated memory unless the memory controller driver module had also called edac_mc_add_mc(). Now edac_mc_free() will check if the newly embedded struct device has been registered with sysfs before using either the standard device release functions or freeing the data structures itself with logic pulled out of the error path of edac_mc_alloc().

Should be "row" and "tot_csrows" respectively. Which means either memory leak, or out-of-bound reads (which if does not trigger an immediate page fault error, will further lead to kfree() on random addresses). L425: The inner loop is reusing the same iterator "chn" as the outer loop, which could lead to premature end of the outer loop, and hence memory leak. L429: The array index 'i' in mci->csrows[i] is a temporary value used in previous loops, and won't change at all in the current loop. Which means either out-of-bound read and possibly kfree(random number), or the same mci->csrows[i] get freed once and again, and possibly double free for the kfree(csr) in L427. L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory. The buggy code was introduced by commit de3910eb ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1 merge window.

coretemp_init loops with for_each_online_cpu, adding platform_devices and sysfs interfaces, then calls register_hotcpu_notifier. There is a race if a CPU is offlined or onlined after the loop, but before register_hotcpu_notifier. The race might result in the absence of a platform_device+sysfs interface for an online CPU, or the presence of a platform_device+sysfs interface for an offline CPU. A similar race occurs during coretemp_exit, after the module calls unregister_hotcpu_notifier, but before it unregisters all devices, a CPU might offline and a device for an offline CPU will exist for a short while. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus.

Nestor Lopez Casado authored
This patch fixes an issue introduced after commit 4ea54542 ("HID: Fix race condition between driver core and ll-driver"). After that commit, hid-core discards any incoming packet that arrives while hid driver's probe function is being executed. This broke the enumeration process of hid-logitech-dj, that must receive control packets in-band with the mouse and keyboard packets. Discarding mouse or keyboard data at the very begining is usually fine, but it is not the case for control packets. This patch forces a re-enumeration of the paired devices when a packet arrives that comes from an unknown device. Based on a patch originally written by Benjamin Tissoires.

Pull networking updates from David Miller: "More bug fixes, nothing gets past these guys" 1) More kernel info leaks found by Mathias Krause, this time in the IPSEC configuration layers. 2) When IPSEC policies change, we do not properly make sure that cached routes (which could now be stale) throughout the system will be revalidated. Fix this by generalizing the generation count invalidation scheme used by ipv4. From Nicolas Dichtel. 3) When repairing TCP sockets, we need to allow to restore not just the send window scale, but the receive one too. Extend the existing interface to achieve this in a backwards compatible way. From Andrey Vagin. 4) A fix for FCOE scatter gather feature validation erroneously caused scatter gather to be disabled for things like AOE too. From Ed L Cashin. 5) Several cases of mishandling of error pointers, from Mathias Krause, Wei Yongjun, and Devendra Naga. 6) Fix gianfar build, from Richard Cochran. 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao Hongjiang. 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder. 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde. 10) The removal of the conditional compilation of the clk support code in the stmmac driver broke things. This is because the interfaces used are the ones that don't also perform the enable/disable of the clk. Fix from Stefan Roese. 11) The QFQ packet scheduler can record out of range virtual start times, resulting later in misbehavior and even crashes. Fix from Paolo Valente. 12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the receiver when the advertised receive window goes to zero. Detect this case and force the processing of the IOAT DMA queue when it happens to avoid getting stuck. Fix from Michal Kubecek. 13) batman-adv assumes that test_bit() returns only 0 or 1, but this is not true for x86 (which returns -1 or 0, via the 'sbb' instruction). Fix from Linus Lussing. 14) Fix small packet corruption in e1000, from Tushar Dave. 15) make_blackhole() in the IPSEC policy code can do one read unlock too many, fix from Li RongQing. 16) The new tcp_try_coalesce() code introduced a bug in TCP URG handling, fix from Eric Dumazet. 17) Fix memory leak in __netif_receive_skb() when doing zerocopy and when hit an OOM condition.
