* ieee1394: write broadcast_channel only to select nodes (fixes device ↵Stefan Richter2005-12-12
| | | | | | | | | | | | | | | | | | recognition) Some old 1394-1995 SBP-2 bridges would hang if they received a broadcast write request to BROADCAST_CHANNEL before the config ROM was read. Affected devices include Datafab MD2-FW2 2.5" HDD and SmartDisk VST FWCDRW-V8 portable CD writer. The write request is now directed to specific nodes instead of being broadcast to all nodes at once, and it is only performed if a previous read request at this register succeeded. Fixes an old interoperability problem which was perceived as a 2.6.14-specific regression: http://marc.theaimsgroup.com/?t=113190586800003 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jody McIntyre <scjody@modernduck.com> (cherry picked from 61c7f775ca25ccfc0e51486103a724fb1a3a08f2 commit)
* ieee1394: resume remote ports when starting a host (fixes device recognition)Stefan Richter2005-12-12
| | | | | | | | | | | | | After initializing an IEEE 1394 host, broadcast a resume packet. This makes remote nodes visible which suspended their ports while the host was down. Such nodes had to be unplugged and replugged in order to be recognized. Motorola DCT6200 cable reciever was affected, probably other devices too. http://marc.theaimsgroup.com/?t=113202715800001 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jody McIntyre <scjody@modernduck.com> (cherry picked from 14c0fa243b358c24040ff5f44b60c47aaf6430c3 commit)

* Link USB drivers later in the kernelLinus Torvalds2005-12-03
| | | | | | | | | | | | We want to link the "regular" SCSI drivers before the USB storage driver, since historically we've always detected internal SCSI disks before the external USB storage modules. The link order matters for initcall ordering, and this got broken by mistake by commit 7586269c0b52970f60bb69fcb86e765fc1d72309 which moved the USB host controller PCI quirk handling around.

| | | | | | | | | | | | | | | | | | | | | | sg's st_map_user_pages is modelled on an earlier version of st's sgl_map_user_pages, and has the same bug: if get_user_pages got some but not all of the pages, then those got were released, but the positive res code returned implied that they were still to be freed.

| * [SCSI] sg and st unmap_user_pages allow PageReservedHugh Dickins2005-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages BUG on a PageReserved page. But that's wrong: they could be unmapping the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while get_user_pages is still permitted on VM_PFNMAP areas - that may change). More change is needed here: sg claims to dirty even pages written from, and st claims not to dirty even pages read into; and SetPageDirty is not adequate for this nowadays. Fixes to those follow in a later patch: for the moment just fix the 2.6.15 regression.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nick and I had already been looking at drivers/scsi/{sg.c,st.c}, brought there by __put_page in sg.c's peculiar sg_rb_correct4mmap, which we'd like to remove. But that's irrelevant to your pain, except... One extract from the patches I'd like to send Doug and Kai for 2.6.15 or 2.6.16 is this below: since the incomplete get_user_pages path omits to reset res, but has already released all the pages, it will result in premature freeing of user pages, and behaviour just like you've seen. Though I'd have thought incomplete get_user_pages was an exceptional case, and a bit surprised you'd encounter it. Perhaps there's some other premature freeing in the driver, and this instance has nothing whatever to do with it. If the problem were easily reproducible, it'd be great if you could try this patch; but I think you've said it's not :-( Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] SPI DV: be more conservative about echo buffer usageJames Bottomley2005-12-01
| | | | | | | | | | | | | | | | | | | | | | Some SCSI devices apparently get very confused if we try to use the echo buffer on a non-DT negotiated bus (this mirrors the problems of using PPR on non-LVD for some devices). The fix is to be far more conservative about when we use an echo buffer. With this patch, we'll now see what parameters are negotiated by the read only test, and only look for an echo buffer if DT is negotiated.

| * [SCSI] aic7xxx: reset handler selects a wrong commandVasily Averin2005-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To transport scsi reset command to device aic7xxx reset handler looks at the driver's pending_list and searches any proper command. However the search condition has been inverted: ahc_match_scb() returns TRUE if a matched command is found. As a result the reset on required devices did not turn out well, a correctly working neighbour device may be surprised by the reset. aic7xxx reset handler reports about the success, but really the original situation is not corrected yet.

This has finally bitten me on one of our systems (heavy network traffic during start up, RX channel is stopped several times to configure multicast list). Graceful channel stop can take up to 1 frame time, so I've added device specific timeout counter which depends on current link speed and calls to udelay() to really wait required amount of time before giving up.
