| * | [SG] Get rid of __sg_mark_end()Jens Axboe2007-11-021-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* | libata: increase 128 KB / cmd limit for ATAPI tape drivesTony Battersby2007-11-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

Combined with previous changes, this now makes device errors for all direct commands reported directly to the issuer without going through EH actions and reporting. Note that EH is still invoked after non-IO device errors to determine the nature of the error and resume command execution (some controller requires special care after error to continue). It just performs default maintenance after error, examines what's going on, realizes that it's none of its business and reports the command failure without logging any error messages.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 2e1c49db4c640b35df13889b86b9d62215ade4b6. First off, testing in Fedora has shown it to cause boot failures, bisected down by Martin Ebourne, and reported by Dave Jobes. So the commit will likely be reverted in the 2.6.23 stable kernels. Secondly, in the 2.6.24 model, x86-64 has now grown support for SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the bug is not visible any more, it's become invisible due to the code just being irrelevant and no longer enabled on the only architecture that this ever affected.

This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy.

As 0xff status is interpreted as no device (for good reasons), this can lead to misdetection on such cases. This patch implements ata_wait_after_reset() which replaces the 150ms sleep and waits upto ATA_TMOUT_FF_WAIT if status is 0xff. ATA_TMOUT_FF_WAIT is currently 800ms which is enough for HHD424020F7SV00 to get detected but not enough for Quantum GoVault drive which is known to take upto 2s. Without parallel probing, spending 2s on 0xff port would incur too much delay on ata_piix's which use 0xff to indicate empty port and doesn't have SCR register, so GoVault needs to wait till parallel probing.

Till now, when a command is issued to a device in SLEEP mode, the command times out, which makes EH reset the device and retry the command after that, causing a long delay. This patch makes libata track SLEEP state and issue SRST automatically if a command is about to be issued to a device in SLEEP.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the locking to work, only the tag map and tag bit map may be shared (incidentally, I was just explaining this to Nick yesterday, but I apparently didn't review the code well enough myself). But we also share the busy list! The busy_list must be queue private, or we need a block_queue_tag covering lock as well. So we have to move the busy_list to the queue. This'll work fine, and it'll actually also fix a problem with blk_queue_invalidate_tags() which will invalidate tags across all shared queues. This is a bit confusing, the low level driver should call it for each queue seperately since otherwise you cannot kill tags on just a single queue for eg a hard drive that stops responding. Since the function has no callers currently, it's not an issue. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| * [NET] napi: use non-interruptible sleep in napi_disableBenjamin Herrenschmidt2007-10-261-1/+1
| | | | | | | | | | | | | | | | | | | | The current napi_disable() uses msleep_interruptible() but doesn't (and can't) exit in case there's a signal, thus ending up doing a hot spin without a cpu_relax. Use uninterruptible sleep instead. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | * [DCCP]: Convert Reset code into socket error numberGerrit Renker2007-10-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for converting the 11 currently defined Reset codes into system error numbers, which are stored in sk_err for further interpretation. This makes the externally visible API behaviour similar to TCP, since a client connecting to a non-existing port will experience ECONNREFUSED. * Code 0, Unspecified, is interpreted as non-error (0); * Code 1, Closed (normal termination), also maps into 0; * Code 2, Aborted, maps into "Connection reset by peer" (ECONNRESET); * Code 3, No Connection and Code 7, Connection Refused, map into "Connection refused" (ECONNREFUSED); * Code 4, Packet Error, maps into "No message of desired type" (ENOMSG); * Code 5, Option Error, maps into "Illegal byte sequence" (EILSEQ); * Code 6, Mandatory Error, maps into "Operation not supported on transport endpoint" (EOPNOTSUPP); * Code 8, Bad Service Code, maps into "Invalid request code" (EBADRQC); * Code 9, Too Busy, maps into "Too many users" (EUSERS); * Code 10, Bad Init Cookie, maps into "Invalid request descriptor" (EBADR); * Code 11, Aggression Penalty, maps into "Quota exceeded" (EDQUOT) which makes sense in terms of using more than the `fair share' of bandwidth.

| | * [DCCP]: Retrieve packet sequence number for error reportingGerrit Renker2007-10-241-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem when analysing erroneous packets in dccp_v{4,6}_err: * dccp_hdr_seq currently takes an skb * however, the transport headers in the skb are shifted, due to the preceding IPv4/v6 header. Fixed for v4 and v6 by changing dccp_hdr_seq to take a struct dccp_hdr as argument. Verified that the correct sequence number is now reported in the error handler.

Anyone who think otherwise deserves compiler warning. Signed-off-by: Alexey Dobriyan <adobriyan@sw.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
