Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Examine all occurrences of sprintf(), strcat(), and str[n]cpy() for possible buffer overflow problems. Replaced most sprintf()'s with snprintf(); for others cases, added terminating NUL bytes where appropriate, replaced constants like "16" with sizeof(), etc. These changes include several bug fixes, but most changes are for maintainability's sake. Any instance where it wasn't "immediately obvious" that a buffer overflow could not occur was made safer.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

* return and stop the current command.
*
* 2. Issue a retry (like I made it do) thus hopefully
* recovering the current transfer, and ignoring the
* fact that we've dropped a command.
*
* These should probably be handled in a device specific

Fix 'camcontrol inquiry'. The inquiry data structure changes (increased to 256 bytes) caused it to break on many devices. The SCSI spec says that for commands with 8-bit length fields, a value of 0 means 256 bytes. As it turns out, many devices don't deal with that properly. Some interpret the 0 as 0, and return no data. Others return more than 256 bytes of data, and cause an overrun. The fix is to tell the device we've only allocated SHORT_INQUIRY_LENGTH (36 bytes) of inquiry data, instead of sizeof(struct scsi_inquiry_data). camcontrol.c: Change inq_len in the call to scsi_inquiry() to SHORT_INQUIRY_LENGTH, and add a long comment explaining the reason for the change. scsi_all.h: Add a comment above the definitinon of SHORT_INQUIRY_LENGTH alerting people that it is both the initial probe inquiry length, and the minimum amount of data needed for scsi_print_inquiry() to function. scsi_all.c: Add a comment about SHORT_INQUIRY_LENGTH being the minimum amount of data needed for scsi_print_inquiry() to function.

Fix the CAM code so that people can compile kernels with the CD driver but without the DA driver. The problem was that the CD driver depended on scsi_read_write() and scsi_start_stop(), which were defined in scsi_da.c. I moved both functions, and their associated data structures and defines from scsi_da.* to scsi_all.*. This is technically the "wrong" thing to do since those commands are really only for direct-access type devices, not for all SCSI devices. I think, though, that the advantage (allowing people to compile kernels without the disk driver) outweighs any architectural purity arguments. PR: kern/7969 Reviewed by: gibbs

Fix the CAM code so that people can compile kernels with the CD driver but without the DA driver. The problem was that the CD driver depended on scsi_read_write() and scsi_start_stop(), which were defined in scsi_da.c. I moved both functions, and their associated data structures and defines from scsi_da.* to scsi_all.*. This is technically the "wrong" thing to do since those commands are really only for direct-access type devices, not for all SCSI devices. I think, though, that the advantage (allowing people to compile kernels without the disk driver) outweighs any architectural purity arguments. PR: kern/7969 Reviewed by: gibbs
