ad 9f19801f75 add boilerplate missed in initial commit 2009-04-10 22:29:30 +00:00
reinoud 49f0ea0bd0 KGDB does no longer refers to ddb/db_access. Fixes compilation problems of KGDB 
kernels.

ad 912b4160fd Make 'show event', 'dmesg' work with crash(8). 
XXX dmesg fails exactly the same way as /sbin/dmesg.
 2009-03-21 13:06:39 +00:00
dsl 454af1c0e8 Change about 4500 of the K&R function definitions to ANSI ones. 
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

dsl 02cdf4d2c8 Remove all the __P() from sys (excluding sys/dist) 
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

martin 7d53797861 Switch the default value (if no options DDB_ONPANIC is defined) for 
ddb.onpanic to 1, change it back to 0 in sysctl.conf and make sure
postinstall installs this setting.
This avoids us trying to dump while booting from install CD, but keeps
the default the same once we are far enough through /etc/rc.d. Failing
earlier is unlikely to be recovered by an automatic reboot.
OK: core.

nakayama 3a99fdb328 Avoid "warning: cast from pointer to integer of different size" 
on 32-bit sparc64 kernels.
 2009-03-11 13:29:44 +00:00
mrg d2ea53a056 include <stdbool.h> if not _KERNEL, and don't include kauth.h if _KERNEL. 
now crash builds on i386.
 2009-03-09 06:07:05 +00:00
mrg e4d97b1066 include <sys/user.h> 2009-03-08 11:41:47 +00:00
mrg 4540375faf include ddb headers *after* sys/types.h or sys/param.h. 2009-03-08 11:40:00 +00:00
ad cd6b1c8f08 Make ddb compile and work in userspace. Mostly this is comprised of three 
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
  and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.

haad 87b8a8844f Do not set last_count to zero after every db_command function call it is 
static variable. This should fix PR 40712.
 2009-03-01 12:13:12 +00:00
yamt f68e4571e5 - fix vmem unittest. rename VMEM_DEBUG so that it won't be abused again. 
- reimplement vmem sanity checks with less code duplication.
- reimplement ddb vmem-related commands in a more consistent ways.
  remove automatic whatis.
 2009-02-18 13:31:59 +00:00
ad 563a207d33 Default 'show all procs' to /l. People tend to type 'ps' without modifiers 
when providing information about deadlocks. Without the thread info it's
not very useful.
 2009-02-04 20:17:58 +00:00
ad 6e89a762d6 Default DDB_ONPANIC to zero. The end product is ultimately for the 
consumption of users external to the project, users who are unlikely to
be kernel hackers with the motivation to debug crashes. In this situation
rebooting and creating a crash dump is more appropriate than interrupting
normal service for an unbounded amount of time, while also leaving the
machine at cryptic db> prompt.
 2009-01-30 21:30:56 +00:00
haad 128703a537 Fix my bug introduced in rev 1.98 of db_command.c where command prefix 
not ambiguous in one table was choosed even if it was ambiguous in another
table in same list. Also apply more KNF rules.

Patch was supplied by uwe@.

cegger 10de0e2b14 ddb: new 'show vmem' and 'show all vmems' commands. 
Useful to inspect vmem(9) structures.

martin 719a906ef5 As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap 
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
 2008-11-30 18:21:31 +00:00
nakayama 4cb83f9c6e Make DDB shows right register values on 32-bit sparc64 kernels. 
- define db_expr_t as int64_t.
- %gsr is 32-bit, so use db_sparc_intop.
- sync arguments with function prototype.
- ansify.

rmind 03fe669395 - Fix message queue permissions problems. 
- Rake into account umask when creating mqueue.
- Restore DDB command, which was accidentally lost (hi martin).
- Misc.

given struct proc and, if LOCKDEBUG is built in, the lock status of
the uvmobject.

martin d5ed42ea19 When doing a reboot from ddb, set panicstr, so that later LOCKDEBUG checks 
show the same mercy as with a real panic.

perry b6a2ef7569 Convert many of the uses of __attribute__ to equivalent

uwe 85dcbb2bb9 db_cmd_search: When we compare names we'd better stop at the nul byte. 
Don't flip-flop between found and ambiguous.  (hi, martin!)
 2007-10-14 00:37:56 +00:00
martin 28da38cbee Fix command name matching, avoid jumps to null function pointers and 
some minor cosmetics.
 2007-10-12 09:53:07 +00:00
martin cd2cd2dd63 Do another setjmp right before entering the command loop, we do not want 
to execute the on-enter commands again on errors.
 2007-10-08 15:06:26 +00:00
martin 9b58206ecf Some cleanup: 
- When registering command tables, make sure the builtin commands are
   already registered
 - Make the command table entry structure private
 - Do not bother to store the number of commands in a table, we can quickly
   calc that if needed.
 2007-10-02 08:47:26 +00:00
martin cadfc6aaa0 No need to db_init_commands() early any more - it will happen on first 
entry to ddb.
 2007-10-01 22:05:15 +00:00
martin 463076317b Special case the initialization of builtin command tables to avoid using 
malloc. Fixes PR kern/37042.
Allow "mach" commands registered by LKMs even if there is no builtin
mach command for the arch.
 2007-10-01 22:01:38 +00:00
martin 34bb6e19fd Minor clenaup - db_cmd_loop_done is a bool nowadays, so use true/false 
instead of 0/1.
Also make db_init_commands() non-static.
 2007-09-23 23:55:54 +00:00
martin 99423a9d7c Simplify the "tables are already setup" test. 
Print a message on unknown commands (as we used to do before) and get rid
of the now unused macro previously used for that.
