2007-12-223c574 and 3c589 endianness fixes (.24?)Al Viro
Both store MAC address in CIS; there's no decoder for that type (0x88) so the drivers work with raw data. It is byteswapped, so ntohs() works for little-endian, but for big-endian it's wrong. ntohs(le16_to_cpu()) does the right thing on both (and always expands to swab16()).

2007-12-20dm crypt: use bio_add_pageMilan Broz
Fix possible max_phys_segments violation in cloned dm-crypt bio. In write operation dm-crypt needs to allocate new bio request and run crypto operation on this clone. Cloned request has always the same size, but number of physical segments can be increased and violate max_phys_segments restriction. This can lead to data corruption and serious hardware malfunction. This was observed when using XFS over dm-crypt and at least two HBA controller drivers (arcmsr, cciss) recently. Fix it by using bio_add_page() call (which tests for other restrictions too) instead of constructing own biovec. All versions of dm-crypt are affected by this bug.

2007-12-20dm: table detect io beyond deviceJun'ichi Nomura
This patch fixes a panic on shrinking a DM device if there is outstanding I/O to the part of the device that is being removed. (Normally this doesn't happen - a filesystem would be resized first, for example.) The bug is that __clone_and_map() assumes dm_table_find_target() always returns a valid pointer. It may fail if a bio arrives from the block layer but its target sector is no longer included in the DM btree. This patch appends an empty entry to table->targets[] which will be returned by a lookup beyond the end of the device. After calling dm_table_find_target(), __clone_and_map() and target_message() check for this condition using dm_target_is_valid(). Sample test script to trigger oops:
2007-12-19[TG3]: Endianness bugfix.Al Viro
tg3_nvram_write_block_unbuffered() is reading data from nvram into allocated buffer before overwriting a part of it with user-supplied data. Then it feeds the entire page back to nvram. It should be storing the words it had read as little-endian, not as host-endian. Note that tg3_set_eeprom() does exactly that for padding the same data to full words before it gets passed down to tg3_nvram_write_block() and then to tg3_nvram_write_block_unbuffered(). Moreover, when we get to sending the entire thing back to nvram, we go through it word-by-word, doing essentially writel(swab32(le32_to_cpu(word)), ...) so if we want them to reach the card in host-independent endianness, we'd better really have all that buffer filled with fixed-endian. For user-supplied part we obviously do have that (it's an array of octets memcpy'd in), ditto for padding of user-supplied part to word boundaries (taken care of in tg3_set_eeprom()). The rest of the buffer gets filled by tg3_nvram_write_block_unbuffered() and it would damn better be consistent with that (and with tg3_get_eeprom(), while we are at it - there we also convert the words read from nvram to little-endian before returning the buffer to user). The bug should get triggered on big-endian boxen when set_eeprom is done for less than entire page. Then the words that should've been unaffected at all will actually get byteswapped in place in nvram. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.

2007-12-19[TG3]: Endianness annotations.Al Viro
Fixed misannotations, introduced a new helper - tg3_nvram_read_le(). It gets __le32 * instead of u32 * and puts there the value converted to little-endian. A lot of callers of tg3_nvram_read() were doing that; converted them to tg3_nvram_read_le(). At that point the driver is practically endian-clean; the only remaining place is an actual bug, AFAICS; will be dealt with in the next patch.

2007-12-17libata: fix ATAPI drainingTejun Heo
With ATAPI transfer chunk size properly programmed, libata PIO HSM should be able to handle full spurious data chunks. Also, it's a good idea to suppress trailing data warning for misc ATAPI commands as there can be many of them per command - for example, if the chunk size is 16 and the drive tries to transfer 510 bytes, there can be 31 trailing data messages. This patch makes the following updates to libata ATAPI PIO HSM implementation. * Make it drain full spurious chunks. * Suppress trailing data warning message for misc commands. * Put limit on how many bytes can be drained. * If odd, round up consumed bytes and the number of bytes to be drained. This gets the number of bytes to drain right for drivers which do 16bit PIO. This patch is partial backport of improve-ATAPI-data-xfer patchset pending for #upstream.

While updating lbam/h for ATAPI commands, atapi_eh_request_sense() was left out. Update it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-12-17libata-acpi: implement _GTF command filteringTejun Heo
Implement _GTF command filtering which can be controlled by libata.acpi_filter kernel parameter. Currently SETXFER and LOCK commands are filtered. libata configures transfer mode by itself and _GTF SETXFER commands can potentially disrupt device configuration. _GTM/_STM mechanism can't handle hotplugging too well and when _GTF is executed, controller is in PIO0 rather than the mode _STM configured. Note that detecting SET MAX LOCK requires looking at the previous command. This adds a bit to code complexity. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-12-17libata-acpi: improve _GTF execution error handling and reportingTejun Heo
As _GTF commands can't transfer data, device error never signals transfer error. It indicates that the device vetoed the operation, so it's meaningless to retry. This patch makes libata-acpi to report and continue on device errors when executing _GTF commands. Also commands rejected by device don't contribute to the number of _GTF commands executed. While at it, update _GTF execution reporting such that all successful commands are logged at KERN_DEBUG and rename taskfile_load_raw() to ata_acpi_run_tf() for consistency.
