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.

After a comparison fails, we + * divide the work in half by moving either left or right. If lim + * is odd, moving left simply involves halving lim: e.g., when lim + * is 5 we look at item 2, so we change lim to 2 so that we will + * look at items 0 & 1. If lim is even, the same applies. If lim + * is odd, moving right again involes halving lim, this time moving + * the base up one item past p: e.g., when lim is 5 we change base + * to item 3 and make lim 2 so that we will look at items 3 and 4. + * If lim is even, however, we have to shrink it by one before + * halving: e.g., when lim is 4, we still looked at item 2, so we + * have to make lim 3, then halve, obtaining 1, so that we will only + * look at item 3. + */ +void * +bsearch(key, base0, nmemb, size, compar) + register const void *key; + const void *base0; + size_t nmemb; + register size_t size; + register int (*compar) __P((const void *, const void *)); +{ + register const char *base = base0; + register size_t lim; + register int cmp; + register const void *p; + + for (lim = nmemb; lim != 0; lim >>= 1) { + p = base + (lim >> 1) * size; + cmp = (*compar)(key, p); + if (cmp == 0) + return ((void *)p); + if (cmp > 0) { /* key > p: move right */ + base = (const char *)p + size; + lim--; + } /* else move left */ + } + return (NULL); +} diff --git a/sys/sys/libkern.h b/sys/sys/libkern.h index c9a3bf3..a1008b8 100644 --- a/sys/sys/libkern.h +++ b/sys/sys/libkern.h @@ -66,6 +66,8 @@ static __inline u_long ulmin(u_long a, u_long b) { return (a < b ? a : b); } /* Prototypes for non-quad routines. */ u_int32_t arc4random __P((void)); int bcmp __P((const void *, const void *, size_t)); +void *bsearch __P((const void *, const void *, size_t, + size_t, int (*)(const void *, const void *))); #ifndef HAVE_INLINE_FFS int ffs __P((int)); #endif diff --git a/sys/sys/sbuf.h b/sys/sys/sbuf.h index 0244466..e2f0a6b 100644 --- a/sys/sys/sbuf.h +++ b/sys/sys/sbuf.h @@ -46,14 +46,15 @@ struct sbuf { int s_flags; /* flags */ }; +__BEGIN_DECLS /* * API functions */ int sbuf_new(struct sbuf *s, char *buf, int length, int flags); void sbuf_clear(struct sbuf *s); int sbuf_setpos(struct sbuf *s, int pos); -int sbuf_cat(struct sbuf *s, char *str); -int sbuf_cpy(struct sbuf *s, char *str); +int sbuf_cat(struct sbuf *s, const char *str); +int sbuf_cpy(struct sbuf *s, const char *str); int sbuf_printf(struct sbuf *s, char *fmt, ...); int sbuf_putc(struct sbuf *s, int c); int sbuf_overflowed(struct sbuf *s); @@ -61,5 +62,6 @@ void sbuf_finish(struct sbuf *s); char *sbuf_data(struct sbuf *s); int sbuf_len(struct sbuf *s); void sbuf_delete(struct sbuf *s); +__END_DECLS #endif diff --git a/usr.bin/kdump/mkioctls b/usr.bin/kdump/mkioctls index b8e4451..143f6cf 100644 --- a/usr.bin/kdump/mkioctls +++ b/usr.bin/kdump/mkioctls @@ -57,8 +57,8 @@ BEGIN { print "#include <netinet6/in6_var.h>" print "#include <netinet6/nd6.h>" print "#include <netinet6/ip6_mroute.h>" - print "#include <cam/cam.h>" print "#include <stdio.h>" + print "#include <cam/cam.h>" print "" print ioctl_includes print "" |
