thorpej 5bc2ba5c36 Oops, missed a couple of pread(2) uses. 1998-06-30 20:40:44 +00:00
thorpej 55c7ea7c28 Use pread(2) and pwrite(2) rather than lseek(2)/{read,write}(2). 1998-06-30 20:29:39 +00:00

mrg 9cd5492c02 - convert unsafe strcpy(), strcat() and sprintf() to the `n' versions. 
- some KNF.

pk dbaf74ae49 Check return value of _kvm_initvtop(). 1996-11-09 23:44:53 +00:00
cgd e79d25e2e9 Don't use a kernel database based on the file name, use only 
/var/db/kvm.db, and only use that if no kernel namelist file
is named.  Update the documentation to describe this.

cgd 8cf4d8ab67 some spaces -> tabs 1996-10-04 03:34:09 +00:00
cgd 2af2958a7d add code so that if kvm_nlist() failed because __fdnlist() failed, 
kvm_geterr() actually provides useful information rather than just an
empty string.
 1996-10-01 18:56:11 +00:00
leo fa72190309 Fix the empty error message problem more completely. When the magic-check 
fails on the cpu_hdr, return 0 instead of -1. This allows the caller to
distinguise between fatal errors and 'nothing there'.
 1996-06-23 20:28:05 +00:00
leo cca068a144 Fix the mysterious empty error message when savecore is executed and no 
dump is present. This was caused by the fact that kvm_dump_mkheader() was
called *before* savecore checks the dump magic and kvm_dump_mkheader() returned
-1 without setting an error message. The latter is fixed now.
 1996-06-23 13:56:54 +00:00
gwr 82118b75d6 Allow more flexibility in the format of cpu_kcore_hdr_t and isolate 
the knowledge of that struct in the machine-dependent module.

leo be74d305c7 Nuke the kd_live argument to kvm_dump_mkheader(). it's not needed anymore... 1996-03-18 21:14:44 +00:00
leo 9c2128ecdd New libkvm/savecore implementation. With the following differences: 
1) savecore will not access the dump or live-kernel directly. It
        will always use the kvm-functions. Allowing it to work on kernels
        that don't have a 1-1 PA-VA mapping.
     2) the kvm-lib has some additional functions to accomplish 1
          - kvm_dump_mkheader()
          - kvm_dump_wrtheader()
          - kvm_dump_inval()
     3) the file formats of the dump generated by the kernel and the dump
        generated by savecore have been changed. The file format now looks
        like the format produced for 'normal' core dumps.
Ports not yet supporting the new kvm-format will be using libkvm.old/
savecore.old for the time being.
 1996-03-16 10:23:29 +00:00
cgd 00fd6050b6 slight type cleanup. add some prototypes for internal functions, 
some 'const' poisoning, some lvalue lossage.
 1995-07-04 03:03:30 +00:00
mycroft 6506fa2b16 Use the new ps_strings format. Find the arguments using their 
addresses in the argv array, rather than guessing based on the location
of NULs.
 1995-05-16 14:21:08 +00:00
mycroft c304971439 Eliminate _kvm_uvatop(), in favor of using the machine-independent VM structures. 1995-01-09 08:59:25 +00:00
mycroft b707f8aa13 Move the swap page buffer into struct __kvm. Cache the page size during 
kvm_open().  Fix an existing memory leak.

Some reorganization of the kernel nlist array.
 1994-02-14 13:46:01 +00:00
chopps 3ed937bcf0 temporary additional lookup of cpu040 for amiga's until new kvm stuff or new 
amiga 040 VM stuff.
 1994-02-14 04:34:42 +00:00
mycroft 22eaa1f29e Always read CLBYTES chunks, and cache the last one read. Don't allocate two 
large arrays statically.

mycroft ababab0671 Forgot to initialize `cp' in setsyserr(). 1993-10-13 15:49:55 +00:00
mycroft db3323c9ef Remove code for old VM system. Don't use page tables in kvm_procread(). 
Change `#if DEBUG' to `#ifdef DEBUG'.  Read some symbols from the kernel
only once.
 1993-10-02 07:07:43 +00:00
mycroft 669b9e506a Last change was almost correct, but we have to check that the pager actually 
has the page.  If not, we go up the shadow chain.
 1993-08-16 07:27:06 +00:00
mycroft 9b8df6ad33 Fix an off-by-one error when scanning the vm map for a page. Also, if the 
page is not in core, don't recurse into shadow objects if we've already found
a pager.
 1993-08-15 13:57:51 +00:00
mycroft cfafc9262a Fix a bug in virtual to physical address translation on hp300s, and add support 
for Amigas.
 1993-08-15 01:54:29 +00:00
cgd 7fa14d416e line 860: use CLSHIFT rather than PGSHIFT. 
line 927: fix bogus indentation
also make sure first chars of buffers are null char, just in
case nothing rational is read...
 1993-08-14 11:47:51 +00:00
cgd b24744dc1d implement kvm_procread for the hp300. now things mostly work on 
the hp300, in terms of kvm.  still minor strangeness re: sendmail...
 1993-08-14 11:44:45 +00:00
mycroft a617b72b1f #include <machine/pte.h>, not <hp300/hp300/pte.h>. Also, make it at least 
compile for non-i386 architectures, but exit with an error message (for now).
 1993-08-14 02:20:27 +00:00
mycroft e9d867ef50 Add RCS identifiers. 1993-08-01 17:54:45 +00:00
mycroft 81c63e588b Read swap in CLBYTES blocks. 1993-07-19 12:37:13 +00:00
deraadt 5c20ccab8b kernel string read function takes much less time. could be optimized further, 
by making block reads kernel page aligned. (cgd will make the next optimization
in this file)
