Kim Phillips authored
The SEC's h/w IV out implementation DMAs the trailing encrypted payload block of the last encryption to ctx->iv. Since the last encryption may still be pending completion, we can sufficiently prevent successive packets from being transmitted with the same IV by xoring with sequence number. Also initialize alg_list earlier to prevent oopsing on a failed probe. Signed-off-by:

- 8-bit interface mode never worked properly. The only adapter I have which supports the 8b mode (the Jmicron) had some problems with its clock wiring and they discovered it only now. We also discovered that ProHG media is more sensitive to the ordering of initialization commands. - Make the driver fall back to highest supported mode instead of always falling back to serial. The driver will attempt the switch to 8b mode for any new MSPro card, but not all of them support it. Previously, these new cards ended up in serial mode, which is not the best idea (they work fine with 4b, after all). - Edit some macros for better conformance to Sony documentation Signed-off-by:

"The camera is an Olympus X-840. The original issue comes from the camera itself: its format program creates a partition with an off by one error". Buggy devices happen. It is better for the kernel to warn and to proceed with the mount. Reported-by:

When suspending the system with atmel_lcdfb enabled, I sometimes see this: atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10 Which can be explained by the fact that we're not stopping the LCD controller and its DMA engine when suspending, we're just gating the clocks to them. There's another potential issue which may be harder to trigger but much more nasty: If we gate the clocks at _just_ the right moment, e.g. when the DMA engine is doing a bus transaction, we may cause the DMA engine to violate the system bus protocol and cause a lockup. Avoid these issues by shutting down the LCD controller before entering suspend (and restarting it when resuming). This prevents the underrun from happening in the first place, and prevents whatever nastiness is happening when the bus clock stops in the middle of a DMA transfer. Signed-off-by:

If you are on ia64 and you modprobe xpc then modprobe -r xpc, you immediately get a panic. xpc depends on xp which depends on gru for a symbol. That symbol is only used when we are running on UV hardware. Currently, the GRU driver detects we are not on UV hardware and does no initializing. It does not do the same check when unloading. As a result, the gru driver attempts to tear down stuff that was not setup. This is a simple two-line workaround to get us through this release. Once 2.6.28 is opened, we need to rework the symbols that xp is depending on from gru so the gru driver can properly fail to load when hardware is not available. Signed-off-by:

The iterator for_each_zone_zonelist() uses a struct zoneref *z cursor when scanning zonelists to keep track of where in the zonelist it is. The zoneref that is returned corresponds to the the next zone that is to be scanned, not the current one. It was intended to be treated as an opaque list. When the page allocator is scanning a zonelist, it marks elements in the zonelist corresponding to zones that are temporarily full. As the zonelist is being updated, it uses the cursor here; if (NUMA_BUILD) zlc_mark_zone_full(zonelist, z); This is intended to prevent rescanning in the near future but the zoneref cursor does not correspond to the zone that has been found to be full. This is an easy misunderstanding to make so this patch corrects the problem by changing zoneref cursor to be the current zone being scanned instead of the next one.

Fixes two DMA bugs in the pxa2xx_spi driver. The first bug is in all versions of this driver; the second was introduced in the 2.6.20 kernel, and prevents using the driver with chips like m25p16 flash (which can issue large DMA reads). 1. Zero length transfers are permitted for use to insert timing, but pxa2xx_spi.c will fail if this is requested in DMA mode. Fixed by using programmed I/O (PIO) mode for such transfers. 2. Transfers larger than 8191 are not permitted in DMA mode. A test for length rejects all large transfers regardless of DMA or PIO mode. Worked around by rejecting only large transfers with DMA mapped buffers, and forcing all other transfers larger than 8191 to use PIO mode. A rate limited warning is issued for DMA transfers forced to PIO mode. This patch should apply to all kernels back to and including 2.6.20; it was test patched against 2.6.20. An additional patch would be required for older kernels, but those versions are very buggy anyway.

Fixes several chipselect bugs in the pxa2xx_spi driver. These bugs are in all versions of this driver and prevent using it with chips like m25p16 flash. 1. The spi_transfer.cs_change flag is handled too early: before spi_transfer.delay_usecs applies, thus making the delay ineffective at holding chip select. 2. spi_transfer.delay_usecs is ignored on the last transfer of a message (likewise not holding chipselect long enough). 3. If spi_transfer.cs_change is set on the last transfer, the chip select is always disabled, instead of the intended meaning: optionally holding chip select enabled for the next message. Those first three bugs were fixed with a relocation of delays and chip select de-assertions. 4. If a message has the cs_change flag set on the last transfer, and had the chip select stayed enabled as requested (see 3, above), it would not have been disabled if the next message is for a different chip. Fixed by dropping chip select regardless of cs_change at end of a message, if there is no next message or if the next message is for a different chip. This patch should apply to all kernels back to and including 2.6.20; it was test patched against 2.6.20. An additional patch would be required for older kernels, but those versions are very buggy anyway. Signed-off-by: -

I recently bought 3 HGST P7K500-series 500GB SATA drives and had trouble accessing the block right on the LBA28-LBA48 border. Here's how it fails (same for all 3 drives): # dd if=/dev/sdc bs=512 count=1 skip=268435455 > /dev/null dd: reading `/dev/sdc': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.288033 seconds, 0.0 kB/s # dmesg ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: BMDMA stat 0x25 ata1.00: cmd c8/00:08:f8:ff:ff/00:00:00:00:00/ef tag 0 dma 4096 in res 51/04:08:f8:ff:ff/00:00:00:00:00/ef Emask 0x1 (device error) ata1.00: status: { DRDY ERR } ata1.00: error: { ABRT } ata1.00: configured for UDMA/33 ata1: EH complete ... After some investigations, it turned out this seems to be caused by misinterpretation of the ATA specification on LBA28 access. Following part is the code in question: === include/linux/ata.h === static inline int lba_28_ok(u64 block, u32 n_block) { /* check the ending block number */ return ((block + n_block - 1) < ((u64)1 << 28)) && (n_block <= 256); } HGST drive (sometimes) fails with LBA28 access of {block = 0xfffffff, n_block = 1}, and this behavior seems to be comformant. Other drives, including other HGST drives are not that strict, through. >From the ATA specification: (http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf) 8.15.29 Word (61:60): Total number of user addressable sectors This field contains a value that is one greater than the total number of user addressable sectors (see 6.2). The maximum value that shall be placed in this field is 0FFFFFFFh. So the driver shouldn't use the value of 0xfffffff for LBA28 request as this exceeds maximum user addressable sector. The logical maximum value for LBA28 is 0xffffffe. The obvious fix is to cut "- 1" part, and the patch attached just do that. I've been using the patched kernel for about a month now, and the same fix is also floating on the net for some time. So I believe this fix works reliably. Just FYI, many Windows/Intel platform users also seems to be struck by this, and HGST has issued a note pointing to Intel ICH8/9 driver. "28-bit LBA command is being used to access LBAs 29-bits in length" http://www.hitachigst.com/hddt/knowtree.nsf/cffe836ed7c12018862565b000530c74/b531b8bce8745fb78825740f00580e23 Also, *BSDs seems to have similar fix included sometime around ~2004, through I have not checked out exact portion of the code.
