Rewrite of the CAM error recovery code. Some of the major changes include: - The SCSI error handling portion of cam_periph_error() has been broken out into a number of subfunctions to better modularize the code that handles the hierarchy of SCSI errors. As a result, the code is now much easier to read. - String handling and error printing has been significantly revamped. We now use sbufs to do string formatting instead of using printfs (for the kernel) and snprintf/strncat (for userland) as before. There is a new catchall error printing routine, cam_error_print() and its string-based counterpart, cam_error_string() that allow the kernel and userland applications to pass in a CCB and have errors printed out properly, whether or not they're SCSI errors. Among other things, this helped eliminate a fair amount of duplicate code in camcontrol. We now print out more information than before, including the CAM status and SCSI status and the error recovery action taken to remedy the problem. - sbufs are now available in userland, via libsbuf. This change was necessary since most of the error printing code is shared between libcam and the kernel. - A new transfer settings interface is included in this checkin. This code is #ifdef'ed out, and is primarily intended to aid discussion with HBA driver authors on the final form the interface should take. There is example code in the ahc(4) driver that implements the HBA driver side of the new interface. The new transfer settings code won't be enabled until we're ready to switch all HBA drivers over to the new interface. src/Makefile.inc1, lib/Makefile: Add libsbuf. It must be built before libcam, since libcam uses sbuf routines. libcam/Makefile: libcam now depends on libsbuf. libsbuf/Makefile: Add a makefile for libsbuf. This pulls in the sbuf sources from sys/kern. bsd.libnames.mk: Add LIBSBUF. camcontrol/Makefile: Add -lsbuf. Since camcontrol is statically linked, we can't depend on the dynamic linker to pull in libsbuf. camcontrol.c: Use cam_error_print() instead of checking for CAM_SCSI_STATUS_ERROR on every failed CCB. sbuf.9: Change the prototypes for sbuf_cat() and sbuf_cpy() so that the source string is now a const char . This is more in line wth the standard system string functions, and helps eliminate warnings when dealing with a const source buffer. Fix a typo. cam.c: Add description strings for the various CAM error status values, as well as routines to look up those strings. Add new cam_error_string() and cam_error_print() routines for userland and the kernel. cam.h: Add a new CAM flag, CAM_RETRY_SELTO. Add enumerated types for the various options available with cam_error_print() and cam_error_string(). cam_ccb.h: Add new transfer negotiation structures/types. Change inq_len in the ccb_getdev structure to be "reserved". This field has never been filled in, and will be removed when we next bump the CAM version. cam_debug.h: Fix typo. cam_periph.c: Modularize cam_periph_error(). The SCSI error handling part of cam_periph_error() is now in camperiphscsistatuserror() and camperiphscsisenseerror(). In cam_periph_lock(), increase the reference count on the periph while we wait for our lock attempt to succeed so that the periph won't go away while we're sleeping. cam_xpt.c: Add new transfer negotiation code. (ifdefed out) Add a new function, xpt_path_string(). This is a string/sbuf analog to xpt_print_path(). scsi_all.c: Revamp string handing and error printing code. We now use sbufs for much of the string formatting code. More of that code is shared between userland the kernel. scsi_all.h: Get rid of SS_TURSTART, it wasn't terribly useful in the first place. Add a new error action, SS_REQSENSE. (Send a request sense and then retry the command.) This is useful when the controller hasn't performed autosense for some reason. Change the default actions around a bit. scsi_cd.c, scsi_da.c, scsi_pt.c, scsi_ses.c: SF_RETRY_SELTO -> CAM_RETRY_SELTO. Selection timeouts shouldn't be covered by a sense flag. scsi_pass.[ch]: SF_RETRY_SELTO -> CAM_RETRY_SELTO. Get rid of the last vestiges of a read/write interface. libkern/bsearch.c, sys/libkern.h, conf/files: Add bsearch.c, which is needed for some of the new table lookup routines. aic7xxx_freebsd.c: Define AHC_NEW_TRAN_SETTINGS if CAM_NEW_TRAN_CODE is defined. sbuf.h, subr_sbuf.c: Add the appropriate #ifdefs so sbufs can compile and run in userland. Change sbuf_printf() to use vsnprintf() instead of kvprintf(), which is only available in the kernel. Change the source string for sbuf_cpy() and sbuf_cat() to be a const char . Add __BEGIN_DECLS and __END_DECLS around function prototypes since they're now exported to userland. kdump/mkioctls: Include stdio.h before cam.h since cam.h now includes a function with a FILE * argument.

Add support for reading MAM attributes to camcontrol(8) and libcam(3). MAM is Medium Auxiliary Memory and is most commonly found as flash chips on tapes. This includes support for reading attributes and decoding most known attributes, but does not yet include support for writing attributes or reporting attributes in XML format. libsbuf/Makefile: Add subr_prf.c for the new sbuf_hexdump() function. This function is essentially the same function. libsbuf/Symbol.map: Add a new shared library minor version, and include the sbuf_hexdump() function. libsbuf/Version.def: Add version 1.4 of the libsbuf library. libutil/hexdump.3: Document sbuf_hexdump() alongside hexdump(3), since it is essentially the same function. camcontrol/Makefile: Add attrib.c. camcontrol/attrib.c: Implementation of READ ATTRIBUTE support for camcontrol(8). camcontrol/camcontrol.8: Document the new 'camcontrol attrib' subcommand. camcontrol/camcontrol.c: Add the new 'camcontrol attrib' subcommand. camcontrol/camcontrol.h: Add a function prototype for scsiattrib(). share/man/man9/sbuf.9: Document the existence of sbuf_hexdump() and point users to the hexdump(3) man page for more details. sys/cam/scsi/scsi_all.c: Add a table of known attributes, text descriptions and handler functions. Add a new scsi_attrib_sbuf() function along with a number of other related functions that help decode attributes. scsi_attrib_ascii_sbuf() decodes ASCII format attributes. scsi_attrib_int_sbuf() decodes binary format attributes, and will pass them off to scsi_attrib_hexdump_sbuf() if they're bigger than 8 bytes. scsi_attrib_vendser_sbuf() decodes the vendor and drive serial number attribute. scsi_attrib_volcoh_sbuf() decodes the Volume Coherency Information attribute that LTFS writes out. sys/cam/scsi/scsi_all.h: Add a number of attribute-related structure definitions and other defines. Add function prototypes for all of the functions added in scsi_all.c. sys/kern/subr_prf.c: Add a new function, sbuf_hexdump(). This is the same as the existing hexdump(9) function, except that it puts the result in an sbuf. This also changes subr_prf.c so that it can be compiled in userland for includsion in libsbuf. We should work to change this so that the kernel hexdump implementation is a wrapper around sbuf_hexdump() with a statically allocated sbuf with a drain. That will require a drain function that goes to the kernel printf() buffer that can take a non-NUL terminated string as input. That is because an sbuf isn't NUL-terminated until it is finished, and we don't want to finish it while we're still using it. We should also work to consolidate the userland hexdump and kernel hexdump implemenatations, which are currently separate. This would also mean making applications that currently link in libutil link in libsbuf. sys/sys/sbuf.h: Add the prototype for sbuf_hexdump(), and add another copy of the hexdump flag values if they aren't already defined. Ideally the flags should be defined in one place but the implemenation makes it difficult to do properly. (See above.)
