* module: fix out-by-one error in kallsymsRusty Russell2012-10-311-11/+16
| | | | | | | | | | | | | | | | | | | | Masaki found and patched a kallsyms issue: the last symbol in a module's symtab wasn't transferred. This is because we manually copy the zero'th entry (which is always empty) then copy the rest in a loop starting at 1, though from src[0]. His fix was minimal, I prefer to rewrite the loops in more standard form. There are two loops: one to get the size, and one to copy. Make these identical: always count entry 0 and any defined symbol in an allocated non-init section. This bug exists since the following commit was introduced. module: reduce symbol table for loaded modules (v2) commit: 4a4962263f07d14660849ec134ee42b63e95ea9a LKML: http://lkml.org/lkml/2012/10/24/27 Reported-by: Masaki Kimura <masaki.kimura.kz@hitachi.com> Cc: stable@kernel.org

| * GPIO: mvebu-gpio: Don't initialize the mask_cacheAndrew Lunn2012-10-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the SMP nature of some of the chips, which have per CPU registers, the driver does not use the generic irq_gc_mask_set_bit() & irq_gc_mask_clr_bit() functions, which only support a single register. The driver has its own implementation of these functions, which can pick the correct register depending on the CPU being used. The functions do however use the gc->mask_cache value. The call to irq_setup_generic_chip() was passing IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be initialized to the contents of some random register. This resulted in unexpected interrupts been delivered from random GPIO lines.

| * gpio/omap: fix off-mode bug: clear debounce settings on free/resetJon Hunter2012-10-271-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change was originally titled "gpio/omap: fix off-mode bug: clear debounce clock enable mask on free/reset". The title has been updated slightly to reflect (what should be) the final fix. When a GPIO is freed or shutdown, we need to ensure that any debounce settings are cleared and if the GPIO is the only GPIO in the bank that is currently using debounce, then disable the debounce clock as well to save power. Currently, the debounce settings are not cleared on a GPIO free or shutdown and so during a context restore on subsequent off-mode transition, the previous debounce values are restored from the shadow copies (bank->context.debounce*) leading to mismatch state between driver state and hardware state. This was discovered when board code was doing gpio_request_one() gpio_set_debounce() gpio_free() which was leaving the GPIO debounce settings in a confused state. If that GPIO bank is subsequently used with off-mode enabled, bogus state would be restored, leaving GPIO debounce enabled which then prevented the CORE powerdomain from transitioning. To fix this, introduce a new function called _clear_gpio_debounce() to clear any debounce settings when the GPIO is freed or shutdown. If this GPIO is the last debounce-enabled GPIO in the bank, the debounce will also be cut. Please note that we cannot use _gpio_dbck_disable() to disable the debounce clock because this has been specifically created for the gpio suspend path and is intended to shutdown the debounce clock while debounce is enabled. Special thanks to Kevin Hilman for root causing the bug. This fix is a collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and Santosh Shilimkar. Testing: - This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio, enabling debounce and then freeing the gpio and checking the register contents, the saved register context and the debounce clock state. - Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the ads7846 touchscreen in its board file using the above sequence, and so was failing off-mode tests in dynamic idle. Verified that off-mode tests are passing with this patch.

| * gpio: mvebu: correctly set the value in direction_output()Thomas Petazzoni2012-10-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The ->direction_output() operation of gpio_chip is supposed to set the direction to output but also to set the GPIO to an initial value. Unfortunately, this last part was not done until now, causing for example the LEDs to not be properly set to their default initial value. This patch fixes this by calling the mvebu_gpio_set() function from mvebu_gpio_direction_output() before configuring the GPIO as an output GPIO.

This bug only showed up when non-standard mount options (journal_async_commit and/or journal_checksum) were enabled, and when the file system was not cleanly unmounted, but the root cause was the inode bitmap modifications was not being properly journaled. This could potentially lead to minor file system corruptions (pass 5 complaints with the inode allocation bitmap) after an unclean shutdown under the wrong/unlucky workloads, but it turned into major failure if the journal_checksum and/or jouaral_async_commit was enabled." * tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: fix unjournaled inode bitmap modification

Nix ran into this when using the journal_async_commit mount option, which enables journal checksumming. The ensuing journal replay failures due to the bad checksums led to filesystem corruption reported as the now infamous "Apparent serious progressive ext4 data corruption bug" [ Changed by tytso to only call ext4_journal_get_write_access() only when we're fairly certain that we're going to allocate the inode. ] I've tested this by mounting with journal_checksum and running fsstress then dropping power; I've also tested by hacking DM to create snapshots w/o first quiescing, which allows me to test journal replay repeatedly w/o actually power-cycling the box. Without the patch I hit a journal checksum error every time. With this fix it survives many iterations.

This causes test runs to immediately stop. Over the past 6 or 7 years we've added hacks like explicit unmount -d commands for loop mounts, losetup -d after unmount -d fails, etc, but still the problems persist. Recently, the frequency of loop related failures increased again to the point that xfstests 259 will reliably fail with a stray loop device that was not torn down. That is despite the fact the test is above as simple as it gets - loop 5 or 6 times running mkfs.xfs with different paramters: lofile=$(losetup -f) losetup $lofile "$testfile" "$MKFS_XFS_PROG" -b size=512 $lofile >/dev/null || echo "mkfs failed!" sync losetup -d $lofile And losteup -d $lofile is failing with EBUSY on 1-3 of these loops every time the test is run. Turns out that blkid is running simultaneously with losetup -d, and so it sees an elevated reference count and returns EBUSY. But why is blkid running? It's obvious, isn't it? udev has decided to try and find out what is on the block device as a result of a creation notification. And it is racing with mkfs, so might still be scanning the device when mkfs finishes and we try to tear it down. So, make losetup -d force autoremove behaviour. That is, when the last reference goes away, tear down the device. xfstests wants it *gone*, not causing random teardown failures when we know that all the operations the tests have specifically run on the device have completed and are no longer referencing the loop device.

In con_work(), when BACKOFF is set, if queue_delayed_work() doesn't result in newly-queued work, it simply ignores this condition and proceeds as if no backoff delay were desired. There are two problems with this--one of which is a bug. The first problem is simply that the intended behavior is to back off, and if we aren't able queue the work item to run after a delay we're not doing that. The only reason queue_delayed_work() won't queue work is if the provided work item is already queued. In the messenger, this means that con_work() is already scheduled to be run again. So if we simply set the BACKOFF flag again when this occurs, we know the next con_work() call will again attempt to hold off activity on the connection until after the delay. The second problem--the bug--is a leak of a reference count. If queue_delayed_work() returns 0 in con_work(), con->ops->put() drops the connection reference held on entry to con_work(). However, processing is (was) allowed to continue, and at the end of the function a second con->ops->put() is called. This patch fixes both problems.

But it also checks if the '=y' part exists. It only will install modules if the config exists and is set with '=y'. But as the regex that was used tests: /^CONFIG_MODULES(=y)?/ this will also match: CONFIG_MODULES_USE_ELF_RELA as the '=y' part was optional and it did not test the rest of the line. When this happens, ktest will stop checking the rest of the configs but it will also think that no modules are needed to be installed. What it should do is only jump out of the loop if it actually found a CONFIG_MODULES that is set to true.

Properly assign status returned from the I/O functions. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the introduction of CONFIG_ARCH_MULTIPLATFORM, versatile is no longer the default platform, so we need to enable CONFIG_ARCH_VERSATILE explicitly in order for that to be selected rather than the multiplatform configuration.
