+	* configure.in (HAVE_SOCKETS, HAVE_SOCKADDR_SUN_LEN): New checks.
+
+	* include/glibtop/*.h: Using `GLIBTOP_GUILE' instead of `HAVE_GUILE'
+	so one should be able to use libgtop without guile in an application
+	even if guile is installed.
+
+	* sysdeps/common/mountlist.c: Fixed some `xstrdup' problems.
+
+	* lib/open.c: Now correctly reading server features for
+	`GLIBTOP_METHOD_PIPE'.

+	the server on a 64bit system.
+
+	* sysdeps/common/gnuslib.c: Using `0xffffffff' instead of -1
+	as error code for inet_addr () since on 64bit systems,

+
+1998-06-02  Federico Mena Quintero  <federico@nuclecu.unam.mx>

+	tells `glibtop_open' to use the default server and not
+	to check the environment variables.
+

+	'__s' is a function defined in the sysdeps part and
+	'__p' is a function that needs special priviledges.
+	'__r' is mapped either on '__p' or on '__s'.

+
+	* sysdeps/common/sysdeps.c: now using '__r' functions,

+
+	* sysdeps/linux/*.c: changed call of 'glibtop_init__r',
+	it now takes two additional arguments.
+
+	* examples/{first.c, second.c}: now using 'glibtop_init'
+	instead of 'glibtop_init__r'.
+
+	* include/glibtop/sysdeps.h: added 'dummy' member so
+	'GLIBTOP_SYSDEPS_<feature>' now start with 1.
+
+	* include/glibtop/*.h: we now #define 'glibtop_get_<feature>'
+	as 'glibtop_get_<feature>__l' and 'glibtop_get_<feature>__r'
+	either as the '__p' or the '__s' function.
+
+	* lib/*.c: removed #if's - we now decide at runtime
+	whether to use the server or to call the appropriate
+	function for the sysdeps directory.
+
+1998-05-28  Martin Baulig  <baulig@merkur.uni-trier.de>
+
+	* src/server/main.c: we now use the '__p' functions,
+	but only if the appropriate 'GLIBTOP_SUID_<feature>'
+	has a non-zero value.
+	
+	* configure.in (@machine_incs@): always use 
+	`-I$(top_srcdir)/sysdeps/@sysdeps_dir@'; it's no
+	longer conditional.
+
+	* examples/Makefile.am: removed the '_linux' examples.
+	
+	* sysdeps/linux/*.c: renamed all functions implementing
+	features to '__s'.
+	
+	* lib/*.c: renamed all functions implementing features
+	to '__l'; we only emit code for those functions if the
+ 	corresponding 'GLIBTOP_SUID_<feature>' has a positive value.
+	
+	* include/glibtop/*.h: added some new function suffixes:
+	'__l' is a function defined in the client part;
+	'__s' is a function defined in the sysdeps part and
+	'__p' is a function that needs special priviledges.
+	'__r' is mapped either on '__l' or on '__s'.
+	
+	* sysdeps/linux/glibtop_server.h: New file -
+	defines system dependent constants 'GLIBTOP_SUID_<feature>'
+	being either 'GLIBTOP_SYSDEPS_<feature>'+1 depending upon
+ 	whether or not this feature requires using the server.
+
+	* lib/sysdeps.c: removed that file; it is no longer
+	needed.
+
+1998-05-25  Martin Baulig  <baulig@merkur.uni-trier.de>
+
+	* src/server/main.c: Fixed `broken pipe' error when server
+	is running SUID; accidentally uses setreuid () instead of
+	setregid ().

+===========
+
+	* We have some new ``suffix rules'':
+
+	  '__l' is a function defined in the client part;
+	  '__s' is a function defined in the sysdeps part and
+	  '__p' is a function that needs special priviledges.
+	  '__r' is mapped either on '__p' or on '__s'.
+	  the function without suffix is mapped on '__l'.
+
+	* We now decide at runtime whether or not using the server
+	is required for a particular function. All user programs
+	now call the '__l' function defined in '-lgtop' (in the lib
+	subdir). These functions either use 'glibtop_call__l' to
+	call the server or call the '__r' function.
+
+	* A function in the sysdeps directory now has the '__s' suffix
+	if it do not need any priviledges (and thus can be called directly
+	from client code) and the '__p' suffix otherwise (when it has to
+	be called from the server).
+
+	* If you call one of these functions:
+
+	  -> use the '__p' suffix to be sure to get the SUID-safe one
+	     (used in the server).
+	  -> use the '__s' suffix to be sure to get a function that
+	     doesn't need any priviledges.
+	  -> use the '__r' suffix otherwise (it is mapped either on the
+	     '__p' or on the '__s' one).
+
+	Only use the '__p' and '__s' functions in a 'GLIBTOP_SUID_<feature>'
+	conditional, otherwise you'll get undefined symbols !
+
+	* The server is now started from 'glibtop_init__r', but only when
+	it's really needed; for instance on DEC OSF/1 you only need it
+	for the proc* features - if you program only fetches the CPU usage,
+	now server will be started.
+
+	* Sorry, at the moment everything is a little bit unstable, I'm doing
+	heavy changes. I've just some great ideas which still need some work:
+
+	  -> I want to have a SUID server that only implements those features
+	     that need to be SUID; everything else uses the sysdeps code directly.
+
+	  -> If a program only uses stuff that do not need the server, the
+	     server will not be started at all.
+
+	  -> I'm working on some kind of proxy server that can be used on a remote
+	     host; in feature one can then use the MDI stuff from ghex in gtop to
+	     have notebook pages displaying processes from different hosts.
+
+	* Well it is as much unstable that it only works under Linux at the moment.

+Request for Comments:
+====================
+
+Should we have a new system call under Linux which fetches information
+from the /proc filesytem similar to the table() function of DEC OSF/1 ?
+
+The whole story:
+===============
+
+I am currently working on libgtop, a library that fetches information
+from the proc filesystem for user processes. This library uses a suid
+server on system where this is required. On Linux, the information are
+fetched directly from the proc filesystem.
+
+Now, I made some profilings (fetches 50000 times cpu, memory, swap,
+uptime and loadavg):
+
+Each sample counts as 0.01 seconds.
+  %   cumulative   self              self     total

+
+You see, it spends a lot of time in read() which is only used to read the
+data from the files in /proc. Well, basically one can say that these
+timings are not so bad, normally a process periodically fetches those
+information say 10 times a seconds which makes 36000 invocations per
+hour.
+
+This will make a total of about 250 seconds per hour or on even say:
+
+``a program fetching those information at a frequency of 10 will take
+  about 7 % of each hour just for reading files from /proc''.
+
+Now look at timings of __ipc, they're about 350 times better 'cause this
+is done using system calls.
+
+So far so good, now look at how this is done on the DEC OSF/1 port of the
+library (the following code is part of libgtop - GPL/LGPL):
+
+CPU usage:
+{
+	struct tbl_sysinfo sysinfo;
+	int ret;
+	
+	ret = table (TBL_SYSINFO, 0, (char *) &sysinfo, 1,
+		     sizeof (struct tbl_sysinfo)); 
+
+	buf->user = sysinfo.si_user;
+	buf->nice = sysinfo.si_nice;
+	buf->sys  = sysinfo.si_sys;
+	buf->idle = sysinfo.si_idle;
+}
+
+Well, the table() command of DEC OSF/1 has may disadvantages, too - such
+as requiring to be root to fetch any information about processes (well, for
+each process that is not the current one).
+
+But this works using system calls rather that reading and parsing files
+and should be about as fast as getting the IPC information on Linux.
+
+Under Linux, the current trend seems to be to move anything into the /proc
+filesystem, but if you look at the timings, wouldn't it be better to also
+implement a system call interface ?
+
+Don't understand me wrong:
+=========================
+
+I *do not want* to *replace* the /proc filesystem - it's an excellent
+idea to be able to fetch all information on the command line without
+any program just a simple 'cat' - I want to *add* a *new* system call
+to allow programmers to fetch those information faster that reading
+from /proc.
+
+To come to the point:
+=====================
+
+Is there any public interest in having a new system call under Linux
+which can be used to fetch all information that are currently in the
+/proc filesystem.
+
+Basically, this system would be defined like this:
+
+	asmlinkage int
+	sys_table (int command, struct sysinfo_table *buf)
+
+and be invoked like this:
+
+	#include <sys/table.h>
+	
+	{
+	  struct sysinfo_cpu cpu;
+	  struct sysinfo_mem mem;
+	
+	  ret = table (TABLE_CPU, &cpu);
+	  if (ret == -1) return; /* or invoke any error handler */
+	
+	  ret = table (TABLE_MEM, &mem);
+	  if (ret == -1) return;
+	}
+
+What do you think, folks. Should we have such a system call under Linux ?
+I can do the implementation of this system call, but I want to have some
+feedback first.

+	Under <productname>Linux</productname>, reading from
+	<filename>/proc</filename> is somehow slow because the data
+	needs to be converted into a stringified representation from
+	the kernel and to be parsed from the application program to
+	get the original data back.
+
+	While doing the <productname>DEC OSF/1</productname> port of
+	&libgtop; I got the idea to add something similar to the &table;
+	function there to the Linux kernel.
+
+	This is what this document is about.

+
+    <para>
+      Some weeks ago, I posted the initial proposal of the project to
+      <ulink url="news:&news-c-o-l-d-s;">&news-c-o-l-d-s;</ulink> with
+      Message-ID <literal>&lt;of7zpfprs08.fsf@Taurus.uni-trier.de&gt;</literal>.
+
+    <para>
+      You can also read this article at my site:

+	  <ulink url="&table-announce-first;">&table-announce-first;</ulink>
+      </itemizedlist>
+
+    <para>
+      Some people told me to include all the stuff into
+      <function>sysctl</function> instead of inventing a new system call.
+
+    <para>
+      Basically this is a good idea, but the main problem with
+      <function>sysctl</function> is that this should be applied to standard
+      kernels and not just as a short patch. Well, AFAIK something similar
+      is on the "wish list" for 2.2er kernels - but of cause it'll need some
+      time until we have a real replacement of the <filename>/proc</filename>
+      filesystem in <function>sysctl</function>.
+
+    <para>
+      If someone thinks that this absolutely should be included in
+      <function>sysctl</function>: think about some kind of interface,
+      discuss it with the kernel developers, ...
+
+  <chapter id="about-table">
+    <title>About the &table; function</title>
+
+    <para>
+      Using the &table; function will not affect any existing kernel
+      structures and can be done independent from kernel development.
+
+    <para>
+      So it can easily be used in &libgtop; until we have something
+      simliar in standard kernels.
+
+    <para>
+      If you want to use the &table; function in your own programs, be
+      aware that it is just intended to be some kind of quick solution
+      for &libgtop; until there's something better in standard kernels.
+
+  <chapter id="how-to-use">
+    <title>How to use the &table; function in &libgtop;</title>
+
+    <para>
+      The source code of the &table; function is distributed together with
+      &libgtop;. It can be found in the <filename>kernel/table20</filename>
+      directory for 2.0.xx kernels and in the <filename>kernel/table21</filename>
+      directory for 2.1.xx kernels.
+
+    <para>
+      You can also download it from my site:
+      
+      <itemizedlist>
+	<listitem><para>
+	    <ulink url="&table20-tgz;">&table20-tgz</ulink>
+	    (for kernel 2.0.xx)
+	<listitem><para>
+	    <ulink url="&table21-tgz;">&table21-tgz</ulink>
+	    (for kernel 2.1.xx)
+      </itemizedlist>
+
+    <para>
+      Copy the contents of the appropriate directory to
+      <filename>/usr/src/linux/table</filename>, apply the
+      patch to the kernel and re-configure &libgtop;.
+
+    <para>
+      After that, you can unmount <filename>/proc</filename> and
+      &libgtop; will still work !
+
+      <note>
+	<para>
+	  Maybe one could consider this as a bug, but currently there
+	  isn't a configuration option to disable the &table; function
+	  once you applied the patch ...
+      </note>
+
+      <note>
+	<para>
+	  Currently I'm working on the 2.1.x version to implement some
+	  features newer kernels have - so the 2.0.x version may not
+	  have all features the 2.1.x one has.
+      </note>
+
+      <note>
+	<para>
+	  The 2.1.x version of the &table; function is implemented
+	  as a kernel module. You have to do a
+	  <command>insmod table/module.o</command> manually to use it.
+
+	<para>
+	  This has the advantage that you don't need to reboot if you
+	  want to play around with the code a little bit.

+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+
+mult_lvl_cmp:
+    slick general purpose multi-level compare function I invented.
+sort_depth:
+    the number of levels of functions *to use*.  This means many more levels
+    can be defined than mult_lvl_cmp tres out.  If this is 1 then mult_lvl_cmp
+    is just a trivial wrapper around (*sort_function[0]).
+sort_direction:
+    multiplicative factor for the output of cmp_whatever.
+    1 ==> default order, -1 ==> reverse order, 0 ==> forced equality
+    The 0 bit is the neat part.  Since a value of zero is the code for equality
+    multiplying the output of cmp_foo(a,b) forces a==b to be true.  This is a
+    convenient way to turn sorting off in middle levels of a multi-level sort.
+    If time is a problem, reforming the whole sort_function array to not include
+    these unsorted middle levels will be faster since then cmp_foo won't even
+    be called.  It might simplify some code depending upon how you organize it.
+sort_function[]:
+    array of function pointers that points to our family of comparison functions
+    (I have named them cmp_* but mult_lvl_cmp doesn't care what they're named).
+    This may be declared and initialized like so:
+       int (*sort_function[])(void* a, void* b)={&cmp_foo, &cmp_bar, &cmp_hiho};
+    You could also use my command line '-O' parser below.
+
+Note that we only descend levels until the order is determined.  If we descend
+all levels, that means that the items are equal at all levels, so we return 0.
+Otherwise we return whatever the level's cmp_foo function would have returned.
+This allows whatever default behavior you want for cmp_foo.  sort_direction[]
+reverses this default behavior, but mult_lvl_cmp doesn't decide that ascending
+or descending is the default.  That is the job of your cmp_foo's.

+Using this program on over 700 files in /dev to perform number->name resolution
+took well under 300 microsecs per device number pair on a Pentium 90.  It is
+somewhat tough to time because once the 3 pages have been mapped in, the time is
+almost zero.  For things like top, this method may even be faster in the long
+run.  Those interested can gprof it for me.  This system has the virtue of being
+nearly perfectly adaptable to individual systems, self updating when /dev
+changes and pretty darn fast when it hasn't.  It will be slow for users without
+perms to change the psdevtab file, though.  So this is what I decided was
+reasonable.  If the process does not have perms to create or update
+/etc/psdevtab and it is out of date, we try /tmp/psdevtab.  If /tmp/psdevtab is
+either out of date or unreadable (malicious user creates it and chmods it),
+$HOME/.psdevtab is used.  This secondarily allows for per-user naming of ttys,
+but is really so that at most one user sees only a single delay per /dev
+modification.
+
+To do the timings I did something like this with zsh:
+    a=(`ls -l *(%^@/) | awk '{print $5 $6}' | sed 's/,/ /'`);
+    time ./test $a

+old algorithmic device number <-> device name mappings.
