ata_tf_read_block() has off-by-one error when converting CHS address to LBA. The bug isn't very visible because ata_tf_read_block() is used only when generating sense data for a failed RW command and CHS addressing isn't used too often these days. This problem was spotted by Atsushi Nemoto. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-09-08ahci: make ahci_asus_m2a_vm_32bit_only() quirk more genericTejun Heo1-24/+29
It turns out ASUS M2A-VM isn't the only one with the 32bit DMA problem. Make ahci_asus_m2a_vm_32bit_only() more generic using the new dmi_get_date() and rename it to ahci_sb600_32bit_only(). Cut off date is now pointed to by dmi_system_id->driver_data in "yyyymmdd" format and it's now also allowed to be omitted.

2009-09-08dmi: extend dmi_get_year() to dmi_get_date()Tejun Heo5-25/+76
There are cases where full date information is required instead of just the year. Add month and day parsing to dmi_get_year() and rename it to dmi_get_date(). As the original function only required '/' followed by any number of parseable characters at the end of the string, keep that behavior to avoid upsetting existing users. The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month and date are checked to be in the ranges of [1-9999], [1-12] and [1-31] respectively and any invalid or out-of-range component is returned as zero. The dummy implementation is updated accordingly but the return value is updated to indicate field not found which is consistent with how other dummy functions behave.

2009-09-08dmi: fix date handling in dmi_get_year()Tejun Heo1-2/+3
Year parsing in dmi_get_year() had the following two bugs. * "00" is treated as invalid instead of 2000 because zero return from simple_strtoul() is treated as error. * "0N" where N >= 8 is treated as invalid of 200N because the leading 0 is considered to specify octal. Fix the above two bugs by using endptr to detect invalid number and forcing decimal. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-09-08libata: unbreak TPM filtering by reorganizing ata_scsi_pass_thru()Tejun Heo1-53/+51
ata_scsi_pass_thru() was checking for input sanity and disallowed commands while initializaing qc from scmd. TPM filtering was added right after protocol check at which point tf wasn't initialized properly. This means that TPM filtering has never really worked. This patch fixes the bug by reorganizing ata_scsi_pass_thru() such that qc is fully initialized before checking for invalid conditions which is way less error prone. Discovered while Thilo-Alexander Ginkel was trying debug patches for bko#13416.

2009-09-08sata_sis: convert to slave_linkTejun Heo1-50/+25
During introduction of slave_link, sata_sis slipped through the crack and left with ad-hoc merged SCR access. As SCR status was shared for both the master and slave devices, when only one of the device is online, libata EH would think both are online but would only get valid device signature for the actually present one, which in turn trigger the probing safety net mechanism and make EH retry causing large delay during boot. This patch converts sata_sis to slave_link mechanism. This bug was reported by TAXI in bko#14075. http://bugzilla.kernel.org/show_bug.cgi?id=14075 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: TAXI <taxi@a-city.de> Cc: Uwe Koziolek <uwe.koziolek@gmx.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-09-01sata_sil24: always set protocol override for non-ATAPI data commandsRobert Hancock1-0/+11
The sil24 hardware has a built-in list of commands and associated protocols that gets used by default to decide how to handle a given command. However, if the command is not known to the controller then it presumably assumes it to be a non-data command which then causes protocol mismatch errors if the device ends up requesting data transfer. The new DATA SET MANAGEMENT - Trim command causes this issue since it's a DMA data-out command. Since we should always know best what protocol the command should be using, let's just set the override flag to inform the controller what protocol to use for all non-ATAPI commands with data transfer.

2009-09-01libata: add command name parsing for error outputRobert Hancock5-5/+174
This patch improve libata's output for error/notification messages to allow easier comprehension and debugging: When ATAPI commands issued through the SCSI layer fail, use SCSI functions to print the CDB in human-readable form instead of just dumping out the CDB in hex. Print out the name of the failed command (as defined by the ATA specification) in error handling output along with the raw register contents. When reporting status of ACPI taskfile commands executed on resume, also output the names of the commands being executed (or not) in readable form. Since the extra data for printing command names increases kernel size slightly, a config option has been added to allow disabling command name output (as well as some of the error register parsing) for those highly sensitive to kernel text size.

2009-09-01libata: clear eh_info on reset completionTejun Heo1-3/+9
Resets are done with port frozen but some controllers still issue interrupts during reset and they may end up recording error conditions in ehi leading to unnecessary EH retrials.

2009-08-31ata_piix: parallel scanning on PATA needs an extra lockingBartlomiej Zolnierkiewicz1-1/+13
Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers.

But if there are multiple objects inactive, then they don't have seqnos and the first fence reg among them would be chosen.

2009-08-28inotify: update the group mask on mark additionEric Paris1-0/+4
Seperating the addition and update of marks in inotify resulted in a regression in that inotify never gets events. The inotify group mask is always 0. This mask should be updated any time a new mark is added. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-08-28inotify: fix length reporting and size checkingEric Paris1-3/+5
0db501bd0610ee0c0 introduced a regresion in that it now sends a nul terminator but the length accounting when checking for space or reporting to userspace did not take this into account. This corrects all of the rounding logic. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-08-28inotify: do not send a block of zeros when no pathname is availableBrian Rogers1-3/+5
When an event has no pathname, there's no need to pad it with a null byte and therefore generate an inotify_event sized block of zeros. This fixes a regression introduced by commit 0db501bd0610ee0c0aca84d927f90bcccd09e2bd where my system wouldn't finish booting because some process was being confused by this.
