ba3c0383aa Limit the amount of data copied to the error buffer to _POSIX2_LINE_MAX.
This is the documented size which the user-provided buffer must be.

91a594d823 Change the return value of kvm_read/kvm_write to be -1 on error, to
match the documented interface.

Previously it returned 0 on error.

b787589098 -Wall, which caught a real bug where buflen wasn't being set properly. 2000-03-27 00:33:45 +00:00

c4a7cdb3b6 Use kldsym(2) to lookup symbol values. This avoids the kvm_mkdb juggling
and is module aware.  Yes, this means that kvm_nlist(3) will find symbols
in loaded modules.  The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.

8771870c76 Delete the sf (swapfile) arg to an internal function that used to point to
/dev/drum but has not been used for a LONG time.
Add $FreeBSD$

480bc7e108 Don't open the swap file. The open descriptor for it hasn't been used
for over 5 years since we switched to using procfs for kvm_uread().
This cleanup was motivated by recent breakage of the default swap file
(/dev/drum) when swapon() has not been called.

35e6b695d6 Allow /dev/null as path for the "/dev/mem" file, and assume that people
know what they're doing if they do that.  This will allow ps to use
the kvm_proc.c bits without having access to /dev/mem.

Fix kvm_proc.c to not need /dev/mem for access to argv/envp

d7b100f932 kvm_malloc:
When malloc fails. don't try to memset NULL pointer, it cause core dump
Replace malloc+memset with calloc, theoretically it can do some
optimization of zeroing process internally
Improve error diagnostic

a52219bb33 phkmalloc strikes again! :-) Another use of un-cleared returns from
malloc squashed...

64f14011a8 Fix previous fix to agree with the man page - don't report errors in
kvm_open() if errstr is NULL.

4be4929c2b Get rid of _PATH_UNIX completely; use getbootfile(3) instead.
DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the
tree as quickly as possible.
