2005-08-27[PATCH] sg.c: fix a memory leak in devices seq_file implementationJan Blunck
I know that scsi procfs is legacy code but this is a fix for a memory leak. While reading through sg.c I realized that the implementation of /proc/scsi/sg/devices with seq_file is leaking memory due to freeing the pointer returned by the next() iterator method. Since next() might return NULL or an error this is wrong. This patch fixes it through using the seq_files private field for holding the reference to the iterator object. Here is a small bash script to trigger the leak. Use slabtop to watch the size-32 usage grow and grow. #!/bin/sh while true; do cat /proc/scsi/sg/devices > /dev/null done Signed-off-by: Jan Blunck <j.blunck@tu-harburg.de> Acked-by: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-08-23[PATCH] sil: apply M15W quirk selectively (take 2)Tejun Heo
As SII reports that only original 3112's are affected by M15W quirk, This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk depending on chipsets. As of yet, we don't know exactly which PCI IDs are for original 3112, so M15W quirk is applied to all except for 3512 and 3124. Once more info is avaliable, we can change some of these sil_3112_m15w's to sil_3112. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] libata: implement ata_poll_qc_complete and use it in polling functionsTejun Heo
[PATCH libata-dev-2.6:upstream] implement ata_poll_qc_complete and use it in polling functions Previously, libata polling functions turned irq back on and completed qc commands without holding host lock. This creates a race condition between the polling task and interrupts from other ports on the same host set or spurious interrupt from itself. This patch implements ata_poll_qc_complete which enables irq and completes qc atomically and convert all polling functions. Note: atapi_packet_task() didn't use to turn irq back on or clear ATA_FLAG_NOINTR on error exits. This patch makes it use ata_poll_qc_complete which does both. Note: With this change, ALL invocations of ata_qc_complete() are now done under host_set lock. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] fix atapi_packet_task vs. intr race (take 2)Tejun Heo
Interrupts from devices sharing the same IRQ could cause ata_host_intr to finish commands being processed by atapi_packet_task if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA protocol. This is because libata interrupt handler is unaware that interrupts are not expected during that period. This patch adds ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not expecting interrupts. Note that once proper HSM is implemented for interrupt-driven PIO, this should be merged into it and this flag will be removed. ahci.c is a different kind of beast, so it's left alone. * The following drivers use ata_qc_issue_prot and ata_interrupt, so changes in libata core will do. ata_piix sata_sil sata_svw sata_via sata_sis sata_uli * The following drivers use ata_qc_issue_prot and custom intr handler. They need this change to work correctly. sata_nv sata_vsc * The following drivers use custom issue function and intr handler. Currently all custom issue functions don't support ATAPI, so this change is irrelevant, updated for consistency and to avoid later mistakes. sata_promise sata_qstor sata_sx4 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] Fix HD activity LED with ahciMartin Wilck
Patch: fix wrong HD activity control by ahci driver The ahci driver 1.0 sets the SActive bit on every transaction, causing the LED to light up. The SActive bit is used only for native command queuing (NCQ) which the current driver version doesn't implement. Resetting the SActive bit is the device's responsibility (by sending a "Set Device Bits FIS" to the host adapter) but this is not required in response to non-NCQ commands, and (most) devices don't. Thus the LED stays always on. This patch fixes the LED behavior.

2005-08-10[PATCH] sata: fix sata_sx4 dma_prep to not use sg->lengthTejun Heo
sata_sx4 directly references sg->length to calculate total_len in pdc20621_dma_prep(). This is incorrect as dma_map_sg() could have merged multiple sg's into one and, in such case, sg->length doesn't reflect true size of the entry. This patch makes it use sg_dma_len(sg).

2005-08-08[SCSI] fix target scanning oops with fc transport classJames.Smart@Emulex.Com
We have some nasty issues with 2.6.12-rc6. Any request to scan on the lpfc or qla2xxx FC adapters will oops. What is happening is the system is defaulting to non-transport registered targets, which inherit the parent of the scan. On this second scan, performed by the attribute, the parent becomes the shost instead of the rport. The slave functions in the 2 FC adapters use starget_to_rport() routines, which incorrectly map the shost as an rport pointer. Additionally, this pointed out other weaknesses: - If the target structure is torn down outside of the transport, we have no method for it to be regenerated at the proper parent. - We have race conditions on the target being allocated by both the midlayer scan (parent=shost) and by the fc transport (parent=rport).

2005-08-04[SCSI] fix aic7xxx performance issues since 2.6.12-rc2James Bottomley
Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Removing the SCSI tape module results in an oops in class_device_destroy if any devices are present.

(The bug is old but class_simple_device_remove() did nothing when the class did not exist.) The patch also fixes a "class leak" in init_st() error path.
