2011-07-06PM / Hibernate: Fix free_unnecessary_pages()Rafael J. Wysocki1-1/+5
There is a bug in free_unnecessary_pages() that causes it to attempt to free too many pages in some cases, which triggers the BUG_ON() in memory_bm_clear_bit() for copy_bm. Namely, if count_data_pages() is initially greater than alloc_normal, we get to_free_normal equal to 0 and "save" greater from 0. In that case, if the sum of "save" and count_highmem_pages() is greater than alloc_highmem, we subtract a positive number from to_free_normal. Hence, since to_free_normal was 0 before the subtraction and is an unsigned int, the result is converted to a huge positive number that is used as the number of pages to free. Fix this bug by checking if to_free_normal is actually greater than or equal to the number we're going to subtract from it. Signed-off-by: Rafael J.

2011-07-06fs: fix lock initializationMiklos Szeredi1-10/+20
locks_alloc_lock() assumed that the allocated struct file_lock is already initialized to zero members. This is only true for the first allocation of the structure, after reuse some of the members will have random values. This will for example result in passing random fl_start values to userspace in fuse for FL_FLOCK locks, which is an information leak at best. Fix by reinitializing those members which may be non-zero after freeing. Signed-off-by: Miklos Szeredi <[email protected]> CC: [email protected] Signed-off-by: Linus Torvalds <[email protected]>

The existing macro fails for following scenarios. 1) S5P64X0 channel 1 2) S5PV210 channel 1 The FIFO data level supported in the above SoCs either 64 or 256 bytes depending on the channel. Because of this the TX_DONE is the 25 bit in the status register. The existing macro works for the following scenarios 1) S3C6410 all channels 2) S5PC100 all channels The FIFO data level supported in the above SoCs 64 bytes on all the channels. Because of this the TX_DONE is the 21 bit in the status register. So when we use the existing macro for the non-working SoCs it is not anding with the TX_DONE bit for transmission status check.

2011-07-05vmxnet3: fix starving rx ring whenoc_skb kb failsShreyas Bhatewara2-43/+96
If the rx ring is completely empty, then the device may never fire an rx interrupt. Unfortunately, the rx interrupt is what triggers populating the rx ring with fresh buffers, so this will cause networking to lock up. This patch replenishes the skb in recv descriptor as soon as it is peeled off while processing rx completions. If the skb/buffer allocation fails, existing one is recycled and the packet in hand is dropped. This way none of the RX desc is ever left empty, thus avoiding starvation Signed-off-by: Scott J.

The snd_card->driver field contains a driver name string, and in general it shouldn't contain space or special letters. The commit 2b39535b9e54888649923beaab443af212b6c0fd changed the string copy from card->name, but the long name string may contain such letters, thus it may still lead to a segfault.

2011-07-04ASoC: Tegra: I2S: Ensure clock is enabled when writing regsStephen Warren1-0/+6
The I2S controller needs a clock to respond to register writes. Without this, register writes will at worst hang the CPU. In practice, I've only observed writes being dropped. Luckily, the dropped register writes historically had no effect: TEGRA_I2S_TIMING: The value we wrote was the reset default. TEGRA_I2S_FIFO_SCR: The default was for the FIFOs to request more data when one slot was empty. The requested value was for the FIFOs to request when four slots were empty. The DMA controller in the mainline kernel is configured to burst a single entry at a time into the FIFO, hence there was no issue. The only negative effect was on bus efficiency losses due to an increased number of arbitration attempts. However, in various non-upstream changes, the DMA controller now bursts four entries at a time into the FIFO. If there is only space for one entry, the data is simply dropped. In practice, this resulted in 3/4 of samples being dropped, and playback at 4x the expected rate and pitch. By fixing the clocking issue, this is solved.
