#ifndef _CAMCONTROL_H
#define _CAMCONTROL_H
Add persistent reservation support to camcontrol(8). camcontrol(8) now supports a new 'persist' subcommand that allows users to issue SCSI PERSISTENT RESERVE IN / OUT commands. sbin/camcontrol/Makefile: Add persist.c. sbin/camcontrol/persist.c: New persistent reservation support for camcontrol(8). We have support for all known operation modes for PERSISTENT RESERVE IN and PERSISTENT RESERVE OUT. exceptions noted above. sbin/camcontrol/camcontrol.8: Document the new 'persist' subcommand. In the section on the Transport ID (-I) option, explain what Transport IDs for each protocol should look like. At some point some of this information could probably get moved off in a separate man page, either on Transport IDs alone or a man page documenting the Transport ID parsing code. Add a number of examples of persistent reservation commands. Persistent Reservations are complex enough that the average user probably won't be able to get the commands exactly right by just reading the man page. These examples show a few basic and advanced examples of how to use persistent reservations. sbin/camcontrol/camcontrol.h: Move the definition for camcontrol_optret here, so we can use it for the persistent reservation code. Add a definition for the new scsipersist() function. sbin/camcontrol/camcontrol.c: Add 'persist' to the list of subcommands. Document 'persist' in the help text. sys/cam/scsi/scsi_all.c: Add the scsi_persistent_reserve_in() and scsi_persistent_reserve_out() CCB building functions. Add a new function, scsi_transportid_sbuf(). This takes a SCSI Transport ID (documented in SPC-4), and prints it to an sbuf(9). There are some transports (like ATA, USB, and SSA) for which there is no transport defined. We need to come up with a reasonable thing to do if we're presented with a Transport ID that claims to be for one of those protocols. Add new routines scsi_get_nv() and scsi_nv_to_str(). These functions do a table lookup to go between a string and an integer. There are lots of table lookups needed in the persistent reservation code in camcontrol(8). Add a new function, scsi_parse_transportid(), along with leaf node functions to parse: FC, 1394 and SAS (scsi_parse_transportid_64bit()) iSCSI (scsi_parse_transportid_iscsi()) SPI (scsi_parse_transportid_spi()) RDMA (scsi_parse_transportid_rdma()) PCIe (scsi_parse_transportid_sop()) Transport IDs. Given a string with the general form proto,id these functions create a SCSI Transport ID structure. sys/cam/scsi/scsi_all.h: Update the various persistent reservation data structures to SPC4r36l, but also rename some fields that were previously obsolete with the proper names from older SCSI specs. This allows using older, obsolete persistent reservation types when desired. Add function prototypes for the new persistent reservation CCB building functions. Add a data strucure for the READ FULL STATUS service action of the PERSISTENT RESERVE IN command. Add Transport ID structures for all protocols described in SPC-4. Add a new series of SCSI_PROTO_XXX definitions, and redefine other defines in terms of these new definitions. Add a prototype for scsi_transportid_sbuf(). Change a couple of "obsolete" persistent reservation data structure fields into something more meaningful, based on what the field was called when it was defined in the spec. (e.g. SPC, SPC-2, etc.) Create a new define, SPRI_MAX_LEN, for the maximum allocation length allowed for the PERSISTENT RESERVE IN command. Add data structures and enumerations for the new name/value translation functions. Add data structures for SCSI over PCIe Routing IDs. Bring the PERSISTENT RESERVE OUT Register and Move parameter list structure (struct scsi_per_res_out_parms) up to date with SPC-4. Add a data structure for the transport IDs that can optionally be appended to the basic PERSISTENT RESERVE OUT parameter list. Move SCSI protocol macro definitions out of the VPD page 0x83 definition and combine them with the more up to date protocol definitions higher in the file. Add function prototypes for scsi_nv_to_str(), scsi_get_nv(), scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(), scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(), scsi_parse_transportid_sop(), and scsi_parse_transportid().

This is an overhaul of the mode page handling in camcontrol as well as related patches. These include: * Mode page editting can be scripted. This involves two things: first, if stdin is not a tty, changes are read from stdin rather than invoking $EDITOR. Second, and more importantly, not all modepage entries must be included in the change set. This means that camcontrol can now gracefully handle more intrusive editting from the $EDITOR, including removal or rearrangement of lines. It also means that you can do stuff like: # echo "WCE: 1" | camcontrol modepage da3 -m 8 -e # newfs /dev/da3 # echo "WCE: 0" | camcontrol modepage da3 -m 8 -e * Range-checking on user-supplied input values. modeedit.c now uses the field width specifiers to determine the maximum allowable value for a field. If the user enters a value larger than the maximum, it clips the value to the max and warns the user. This also involved patching cam_cmdparse.c to be more consistent with regards to the "count" parameter to arg_put (previously is was the length of strings and 1 for all integral types). The cam_cdbparse(3) man page was also updated to reflect the revised semantics. * In the process, I removed the 64 entry limit on mode pages (not that we were even close to hitting that limit). This was a nice side-effect of the other changes. * Technically, the new mode editting functionality allows editting of character array entries in mode pages (type 'c' or 'z'), however since buff_encode doesn't grok them it is currently useless. * Camcontrol gained two new options related to mode pages: -l and -b. The former lists all available mode pages for a given device. The latter forces mode page display in binary format (the default when no mode page definition was found in scsi_modes). * Added support for mode page names to scsi_modes. Allows names to be displayed alongside mode numbers in the mode page listing. Updated scsi_modes to use the new functionality. This also adds the semicolon into the scsi_modes syntax as an optional mode page definition terminator. This is needed to name pages without providing a page format definition. * Updated scsi_all.h to include a structure describing mode page headers. * Added $FreeBSD$ line to scsi_modes.

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.) Sponsored by: Spectra Logic Corporation MFC after: 1 week
