This patch makes NFSD file system superblock to be created per net. This makes possible to get proper network namespace from superblock instead of using hard-coded "init_net". Note: NFSd fs super-block holds network namespace. This garantees, that network namespace won't disappear from underneath of it. This, obviously, means, that in case of kill of a container's "init" (which is not a mount namespace, but network namespace creator) netowrk namespace won't be destroyed. Signed-off-by:

If mddev->ro is set, md_to_sync will (correctly) abort. However in that case MD_RECOVERY_INTR isn't set. If a RESHAPE had been requested, then ->finish_reshape() will be called and it will think the reshape was successful even though nothing happened. Normally a resync will not be requested if ->ro is set, but if an array is stopped while a reshape is on-going, then when the array is started, the reshape will be restarted. If the array is also set read-only at this point, the reshape will instantly appear to success, resulting in data corruption. Consequently, this patch is suitable for any -stable kernel.

When removing a (sibling) event we do: raw_spin_lock_irq(&ctx->lock); perf_group_detach(event); raw_spin_unlock_irq(&ctx->lock); <hole> perf_remove_from_context(event); raw_spin_lock_irq(&ctx->lock); ... raw_spin_unlock_irq(&ctx->lock); Now, assuming the event is a sibling, it will be 'unreachable' for things like ctx_sched_out() because that iterates the groups->siblings, and we just unhooked the sibling. So, if during <hole> we get ctx_sched_out(), it will miss the event and not call event_sched_out() on it, leaving it programmed on the PMU. The subsequent perf_remove_from_context() call will find the ctx is inactive and only call list_del_event() to remove the event from all other lists. Hereafter we can proceed to free the event; while still programmed! Close this hole by moving perf_group_detach() inside the same ctx->lock region(s) perf_remove_from_context() has. The condition on inherited events only in __perf_event_exit_task() is likely complete crap because non-inherited events are part of groups too and we're tearing down just the same. But leave that for another patch. Most-likely-Fixes: e03a9a55 ("perf: Change close() semantics for group events") Reported-by:

Joe Perches authored
__ratelimit() can be considered an inverted bool test because it returns true when not ratelimited. Several tests in the kernel tree use this __ratelimit() function incorrectly. No net_ratelimit uses are incorrect currently though. Most uses of net_ratelimit are to log something via printk or pr_<level>. In order to minimize the uses of net_ratelimit, and to start standardizing the code style used for __ratelimit() and net_ratelimit(), add a net_ratelimited_function() macro and net_<level>_ratelimited() logging macros similar to pr_<level>_ratelimited that use the global net_ratelimit instead of a static per call site "struct ratelimit_state".

commit 94e0104b upstream. Commit 1619f441 'rapidio/tsi721: fix bug in MSI interrupt handling' (commit 1ccc819d upstream) makes the MSI handler disable and re-enable interrupts. When re-enabling interrupts, we should set the same flags as were originally set, but this changed in Linux 3.5 so the flags are now inconsistent in 3.2. In fact, the extra flag isn't even defined in 3.2. Remove the extra flag from the MSI handler. Reported-by:

D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb. Signed-off-by:

commit 80a19deb upstream. In 3.2, unlike mainline, efi_pstore_erase() calls efi_pstore_write() with a size of 0, as the underlying EFI interface treats a size of 0 as meaning deletion. This was not taken into account in my backport of commit d80a361d 'efi_pstore: Check remaining space with QueryVariableInfo() before writing data'. The size check should be omitted when erasing.

This patch fixes the bug in reset_store caused by accessing NULL pointer. The bdev gets its value from bdget_disk() which could fail when memory pressure is severe and hence can return NULL because allocation of inode in bdget could fail. Hence, this patch introduces a check for bdev to prevent reference to a NULL pointer in the later part of the code. It also removes unnecessary check of bdev for fsync_bdev().

The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

With recent changes it is possible for the timer handler to detect an idle interface and not start the timer, but the thread to start an operation at the same time. The thread will not start the timer in that instance, resulting in the timer not running. Instead, move all timer operations under the lock and start the timer in the thread if it detect non-idle and the timer is not already running. Moving under locks allows the last timeout to be set in both the thread and the timer. 'Timer is not running' means that the timer is not pending and smi_timeout() is not running. So we need a flag to detect this correctly. Also fix a few other timeout bugs: setting the last timeout when the interrupt has to be disabled and the timer started, and setting the last timeout in check_start_timer_thread possibly racing with the timer Signed-off-by:

All xtables variants suffer from the defect that the copy_to_user() to copy the counters to user memory may fail after the table has already been exchanged and thus exposed. Return an error at this point will result in freeing the already exposed table. Any subsequent packet processing will result in a kernel panic. We can't copy the counters before exposing the new tables as we want provide the counter state after the old table has been unhooked. Therefore convert this into a silent error.

"len" contains sizeof(nf_ct_ext) and size of extensions. In a worst case it can contain all extensions. Bellow you can find sizes for all types of extensions. Their sum is definitely bigger than 256. nf_ct_ext_types[0]->len = 24 nf_ct_ext_types[1]->len = 32 nf_ct_ext_types[2]->len = 24 nf_ct_ext_types[3]->len = 32 nf_ct_ext_types[4]->len = 152 nf_ct_ext_types[5]->len = 2 nf_ct_ext_types[6]->len = 16 nf_ct_ext_types[7]->len = 8 I have seen "len" up to 280 and my host has crashes w/o this patch. The right way to fix this problem is reducing the size of the ecache extension (4) and Florian is going to do this, but these changes will be quite large to be appropriate for a stable tree.

The GHASH setkey() function uses SSE registers but fails to call kernel_fpu_begin()/kernel_fpu_end(). Instead of adding these calls, and then having to deal with the restriction that they cannot be called from interrupt context, move the setkey() implementation to the C domain. Note that setkey() does not use any particular SSE features and is not expected to become a performance bottleneck. Signed-off-by:

When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this warning: drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined but not used [-Wunused-function] Instead of creating nested #ifdefs, this patch fixes it by defining the xHCI PCI stubs as inline. This warning has been in since 3.2 kernel and was caused by commit 421aa841 "usb/xhci: hide MSI code behind PCI bars", but wasn't noticed until 3.13 when a configuration with these options was tried Signed-off-by:

The TXMAXP register is not set correctly for full speed bulk case when the can_bulk_split() is used. Without this PIO transfers will not take place correctly The "mult" factor needs to be updated correctly for the can_bulk_split() case The AUTOSET bit in the TXCSR is not being set if the "mult" factor is greater than 0 for the High Bandwidth ISO case. But the "mult" factor is also greater than 0 in case of Full speed bulk transfers with the packet splitting in TXMAXP register Without the AUTOSET the DMA transfers will not progress in mode1 [ balbi@ti.com : add braces to both branches ] Signed-off-by:

In read_all_bytes, we do unsigned char i; ... bt->read_data[0] = BMC2HOST; bt->read_count = bt->read_data[0]; ... for (i = 1; i <= bt->read_count; i++) bt->read_data[i] = BMC2HOST; If bt->read_data[0] == bt->read_count == 255, we loop infinitely in the 'for' loop. Make 'i' an 'int' instead of 'char' to get rid of the overflow and finish the loop after 255 iterations every time. Signed-off-by:Jiri Slaby <jslaby@suse.cz> Reported-and-debugged-by:

The powernow-k6 driver used to read the initial multiplier from the powernow register. However, there is a problem with this: * If there was a frequency transition before, the multiplier read from the register corresponds to the current multiplier. * If there was no frequency transition since reset, the field in the register always reads as zero, regardless of the current multiplier that is set using switches on the mainboard and that the CPU is running at. The zero value corresponds to multiplier 4.5, so as a consequence, the powernow-k6 driver always assumes multiplier 4.5. For example, if we have 550MHz CPU with bus frequency 100MHz and multiplier 5.5, the powernow-k6 driver thinks that the multiplier is 4.5 and bus frequency is 122MHz. The powernow-k6 driver then sets the multiplier to 4.5, underclocking the CPU to 450MHz, but reports the current frequency as 550MHz. There is no reliable way how to read the initial multiplier. I modified the driver so that it contains a table of known frequencies (based on parameters of existing CPUs and some common overclocking schemes) and sets the multiplier according to the frequency. If the frequency is unknown (because of unusual overclocking or underclocking), the user must supply the bus speed and maximum multiplier as module parameters. This patch should be backported to all stable kernels. If it doesn't apply cleanly, change it, or ask me to change it. Signed-off-by:
