2005-08-28[SCSI] fix sense buffer length handling problemJames Bottomley1-2/+2
The new bio code was incorrectly converted from stack allocated to kmalloc'd buffer handling. There are two places where it incorrectly uses sizeof(*sense) to get the size of the sense buffer. This actually produces one, so no sense data was ever getting back, causing failure in things like disk spin up. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-28[SCSI] fix 3ware raid emulated commandsJames Bottomley1-18/+39
The 3ware emulated commands all expect they are executing in the use_sg == 0 case, which isn't true either in the block layer rework or an SG_IO ioctl. Fix this by adding the correct kmapping of the first element in the sg list. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-08-28[SCSI] convert ch to use scsi_execute_reqJames Bottomley1-21/+17
I also tinkered with it's sense recognition routines to make them take scsi_sense_hdr structures instead of raw sense data. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-28[SCSI] convert sr to scsi_execute_reqJames Bottomley2-74/+37
This follows almost the identical model to sd, except that there's one ioctl which returns raw sense data, so it had to use scsi_execute() instead. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-28[SCSI] convert sd to scsi_execute_req (and update the scsi_execute_req API)James Bottomley5-164/+139
This one removes struct scsi_request entirely from sd. In the process, I noticed we have no callers of scsi_wait_req who don't immediately normalise the sense, so I updated the API to make it take a struct scsi_sense_hdr instead of simply a big sense buffer.

2005-08-28[SCSI] convert SPI transport class to scsi_executeJames Bottomley3-74/+69
This one's slightly more difficult. The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-08-28[SCSI] ibmvscsi timeout fixDave C Boutcher1-1/+1
This patch fixes a long term borkenness in ibmvscsi where we were using the wrong timeout field from the scsi command (and using the wrong units.) Now broken by the fact that the scsi_cmnd timeout field is gone entirely. This only worked before because all the SCSI targets assumed that 0 was default.

2005-08-28[SCSI] use scatter lists for all block pc requests and simplify hw handlersJames Bottomley1-37/+59
Here's the proof of concept for this one. It converts scsi_wait_req to do correct REQ_BLOCK_PC submission (and works nicely in my setup). The final goal should be to eliminate struct scsi_request, but that can't be done until the character submission paths of sg and st are also modified. There's some loss of functionality to this: retries are no longer controllable (except by setting REQ_FASTFAIL) and the wait_req API needs to be altered, but it looks very nice.

2005-08-28[PATCH] Remove race between con_open and con_closePaul Mackerras1-1/+1
[ Same race and same patch also by Steven Rostedt <rostedt@goodmis.org> ] I have a laptop (G3 powerbook) which will pretty reliably hit a race between con_open and con_close late in the boot process and oops in vt_ioctl due to tty->driver_data being NULL. What happens is this: process A opens /dev/tty6; it comes into con_open() (drivers/char/vt.c) and assign a non-NULL value to tty->driver_data. Then process A closes that and concurrently process B opens /dev/tty6. Process A gets through con_close() and clears tty->driver_data, since tty->count == 1. However, before process A can decrement tty->count, we switch to process B (e.g. at the down(&tty_sem) call at drivers/char/tty_io.c line 1626). So process B gets to run and comes into con_open with tty->count == 2, as tty->count is incremented (in init_dev) before con_open is called. Because tty->count != 1, we don't set tty->driver_data. Then when the process tries to do anything with that fd, it oopses. The simple and effective fix for this is to test tty->driver_data rather than tty->count in con_open. The testing and setting of tty->driver_data is serialized with respect to the clearing of tty->driver_data in con_close by the console_sem. We can't get a situation where con_open sees tty->driver_data != NULL and then con_close on a different fd clears tty->driver_data, because tty->count is incremented before con_open is called. Thus this patch eliminates the race, and in fact with this patch my laptop doesn't oops.

2005-08-27[PATCH] sg.c: fix a memory leak in devices seq_file implementationJan Blunck1-7/+6
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>

Don't check type of sax25_family; dev_set_mac_address has already done that before and anyway, the type to check against would have been ARPHRD_AX25. We only got away because AF_AX25 and ARPHRD_AX25 both happen to be defined to the same value. Don't check sax25_ndigis either; it's value is insignificant for the purpose of setting the MAC address and the check has shown to break some application software for no good reason.

2005-08-26Ignore disabled ROM resources at setupLinus Torvalds1-1/+3
Writing even a disabled value seems to mess up some matrox graphics cards. It may be a card-related issue, but we may also be writing reserved low bits in the result. This was a fall-out of switching x86 over to the generic PCI resource allocation code, and needs more debugging. In particular, the old x86 code defaulted to not doing any resource allocations at all for ROM resources. In the meantime, this has been reported to make X happier by Helge Hafting <helgehaf@aitel.hist.no>. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
