* [PATCH] null pointer dereference in appledisplay driverMichael Hanselmann2007-02-121-2/+2
| | | | | | | | | | | | | | Commit 40b20c257a13c5a526ac540bc5e43d0fdf29792a by Len Brown introduced a null pointer dereference in the appledisplay driver. This patch fixes it.

If it is the case that the phy being discovered happens to be the second phy of a wide link to an expander, that discover_dev function will incorrectly call sas_ex_discover_expander, which creates another sas_port and tries to attach the other sas_phys to the new port, thus triggering a BUG. The correct thing to do is to check the other ex_phys of the expander to see if there's a sas_port for this sas_phy, and attach the sas_phy to the existing sas_port. This is easily triggered if one enables the phys of a wide port between expanders one by one. This second version of the patch fixes a small regression in the case where all the phys show up at once and we accidentally try to attach to a port that hasn't been created yet.

Read does trigger it in my system. The bug is not associated with any specific HBA. st tries to do direct i/o in fixed block mode with reads that are not a multiple of tape block size. The patch in this message fixes the st problem by switching to using the driver buffer up to the next close of the device file in fixed block mode if the user asks for a read like this. I don't know why the bug has surfaced only after 2.6.17 although the st problem is old. There may be another bug in the block subsystem and this patch works around it. However, the patch fixes a problem in st and in this way it is a valid fix. This patch may also fix the bug 7900. The patch compiles and is lightly tested.

| * | | [SCSI] fusion - serialize target resets in mptsas.cEric Moore2007-02-022-45/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fusion firmware requires target reset following hotplug removal event, with purpose to flush target outstanding request in fw. Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes. The delayed work tasks are spawned during the target reset completion. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
