GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Introduction
============
cinit is a fast init system with dependency features.
It is orientated on the design off Richard Gooch's
need [0] and Felix von Leitner's minit[1]. Minit does not support real
dependencies (you don't know whether the service you depend on really
started) and the need concept is somehow slow (as seen in gentoo).
In addition, minit needs libowfat and dietlibc, which may not be found
on every Unix system.
cinit main features:
- portability: it should run on every POSIX compatible system.
- true dependencies
- parallel execution
- highly customisable (see conf/*)
Getting cinit
=============
This README is part of the source, so you should have it.
If not, goto the homepage [2] and download the tar archive
or get the lastest snapshot via monotone.
Pre-Configuring
===============
If you want to fine tune cinit parameters, add different path names,
change the DESTDIR, ... have a look at conf/*.
Installing
==========
You can install cinit parallel to any other init-system, it won't
kill other init's config nor /sbin/init, if it exists.
You only have to tell your kernel to execute /sbin/cinit instead
of /sbin/init.
Everybody do:
# make all install
If it's the first time you operate with cinit, also do:
# make install-example
This will populate /etc/cinit with some default services for Linux
(mounting root r/w, starting gettys, setting hostname).
This should work on most Linux systems, still you should have a
look at /etc/cinit and see whether services are correct.
Configuring
===========
You'll have to configure /etc/cinit and add your existing services.
Please read doc/configuring.cinit for details.
sampleconfig.tar is the tar-ball I used for testing, beware if you use it:
It loads dvorak at startup!
There are currently no tools to merge your existing init-system
to cinit (like sysvinit-merge, bsd-merge or minit-merge) available.
If someone cares and tries to do that, I would be happy to include
the script(s).
Additionally I would be thankful for tar-balls containing a complete
replacement of $your_unix_init.
Author, Contact, Bug reports, etc.

- check return values of most functions!
- check errno!
- check whether headers are ok
- remove printfs!
- write manpages (use doc/* as base for that)
- eventually split cinit code to csvc to minimize binary of cinit?
- cleanup comments
- cleanup headers!
- respawn_svc and exec_svc must return pid_t of executed service / watcher
- exec_svc.c: should we also change environment?
- write install-example for non-Linux systems (think of merge also)
- move messages to cinit.h or message.h or conf/msg-*!
- remove MAX_SVC
- change exec_svc to be much more dumb!
*svc, *svc_param_file, *svc_env_file
- remove stat from exec_svc, do before!
- check for possibilies to save ram, free things
- stat() in run_svc -> don't call exec_svc, respawn_svc, run_run_svc
- close(*>2) before forking / executing
- get CTR-ALT-DEL
- check if we caught every signal, which could kill us
- create coala-socket with correct permissions! (550, root:cinit)
- run_svc_new:
o we have many strcat()s, perhaps save length of pathbuf and strncat at
pathtmp[strlen(pathbuf)] ?
o should we check strcat and strcpy return values or do we expect them to work?
--------------------------------------------------------------------------------
- script merge sysVinit to cinit?
- circulaere abhaengigkeiten?
- script vorher?
--------------------------------------------------------------------------------
- create conversion table:
djbdns <-> name_server
dnscache <-> name_caching
qmail,postfix,... <-> MTA
--------------------------------------------------------------------------------
create_mini_cinit
-> create something which should be runnable
-> mount, fsck, getty
--> for dev in `read /etc/fstab` ...
fsck $dev
--> mount -a
--> mount -n -o remount,rw /
--> getty from /etc/inittab or /sbin/*getty
-> find out, which gettys with which params
-> use it on 'make install'
--------------------------------------------------------------------------------
signal handlers:
sa.sa_handler=sigint; sigaction(SIGINT,&sa,0); /* ctrl-alt-del */
sa.sa_handler=sigwinch; sigaction(SIGWINCH,&sa,0); /* keyboard request */
--------------------------------------------------------------------------------
Add support for 'cinit' group, which may shutdown/reboot/halt with
SO_PASSCRED in sockets
--------------------------------------------------------------------------------
Done
- include '/' in C_RUNS? make double strings? -> no.

'Geheimnisse' in German
- Dependencies beginning with a '.' (dot) are ignored.
So you can temporary disable a dependency moving it to
want/.name
- Why is the name of the socket "coala"?
Well, coala could mean 'cinit object abstract layer access', but
perhaps it's a much simpler reason.
- cinit will start a little bit faster, if you omit non needed
'wants' and 'needs' dirs, as they need to be scanned, if they
exist

--------------------------------------------------------------------------------
cinit commands, Nico Schottelius 2005-04-28
--------------------------------------------------------------------------------
cinit allows communication through a socket (see ipc.thoughs for reasons).
Sockets allow to find out the accessing uid, gid and pid (uses SO_PEERCRED as
socketoption).
The communication-protocol is binary.
--------------------------------------------------------------------------------
Protocol overview
--------------------------------------------------------------------------------
Any communication begins with a command. A command is a one byte
unsigned char. Depending on the command, the communication has its own
semantics.
Commands are: (values can be found in cinit.h)
CMD_START_SVC: I want to start a service.
CMD_CHG_STATUS: I want to change the status of a service.
CMD_STOP_SVC: Please shutdown a service and its dependencies.
CMD_KILL_SVC: Shutdown a service, don't care about its dependencies.
CMD_RESCUE: Kill everything, and spawn a sulogin shell.
CMD_INIT: Start all services (again possibly).
CMD_HALT: Halt the system*)

CMD_START_SVC
1. int len; /* length of service name, including \0 */
2. char *svc; /* name of the service, absolute pathname */
cinit returns:
a) ok, a SID, a service ID: int svc_id; [ really need int? ]
b) fail, [currently only fail is returned]
a) already running
b) svc_name too long / not allowed
[ A service identification is used for faster searching in cinit.
It is also a hint for developers of external software, that they should not
be able to use CMD_CHG_STATUS, if they didn't start a service.
They should use CMD_STOP_SVC to stop a service.
Starting a service is currently done via exec() in the external program or
a cinit-fork(). ]
CMD1CHG_STATUS: I want to change the status of a service.
0. int len;
1. char *svc;
2. char status; /* status:
once: started successfully the service once.
fail: tried to start once, but the service exit ungracefully
respawn: I am on it, as soon it exists I'll restart! */
2. pid_t pid /* the pid of the service, if started once
or the pid of the service watcher, if respawning */
cinit returns: MSG_OK|MSG_FAIL (char)
CMD_STOP_SVC: Please shutdown a service and its dependencies.
1. int len; /* length of service name, including \0 */

Thoughts about different UNIX-IPC, Nico Schottelius 2005-04-28
--------------------------------------------------------------------------------
Howto cinit communicates with
a) cinit-forks
b) any other program
a) cinit-forks
a.1) shared memory
Access could generally be done with shared memory. The problem with
that is, that -lrt is required, which implicits -lpthread, which
makes linking staticly problematic (at least for glibc).
a.2) pipes
A maximum of ~510 pipes could be used ( (1024-3)/2),
1024=max fds, -3=already opened (stderr/stdin/stdout), /2=
two fds needed per clients).
Pipes cannot be use easily through forks of forks.
a.3) fifos
FIFOs are easy to use, but you would need to create two FIFOs
for _every_ service, as with only two FIFOs we cannot reliable
detect, _who_ is writting to us currently and who wants to read.
a.4) system-v-ipc
No documentation found nor tested.
a.5) sockets
Are indeed a very clean way. There's only one problem:
bind() fails on read-only mounted devices:
- The socket either does not exists and cannot be created
- or the socket exists, but bind() refuses to reuse it
(error: Address already in use)
Imho bind() should even honour the socket-option SO_REUSEADDR,
which allows to re-use a socket, if there's no other program bound to.
As far as I can see, SO_REUSEADDR is only honoured, if socket is of
type PF_INET (we use PF_UNIX) and POSIX does only specify how to
check for support, but not that sockets have to be able to use
SO_REUSEADDR.
That way, we are forced to mount a temporary filesystem on
/etc/cinit/tmp and create the socket below this directory. This is not
the clean and easy solution one would wish. Still, sockets
seem to be the cleanest and most reliable way to have IPC for
this situation.
See socket(2), bind(2), listen(2), accept(2), socket(7) and unix(7)
for help.
b) any other program
What you can do is to tell cinit to
- reboot,
- halt and
- poweroff.
Simple send cinit a signal, what todo:
SIGUSR1: reboot
SIGUSR2: poweroff
TERM: halt
See signal(2) and signal(7) for help and serv/sig_reboot.c for implementation.

From: Nico Schottelius
Subject: Unix IPC, socket/AF_UNIX; bind on r/o devices?
Date: 09 May 2005 09:51:27 GMT
To: comp.unix.programmer
Hello!
Situation:
- everything mounted readonly (as when starting the system)
- one process with n children, which may have n children (recursive)
- all the children and children of children should be able to talk to the
first parent
Problem:
- Using bind() will fail, because
a) socket cannot created
b) the existing socket cannot be reused
Other possibilities not working:
- shared memory is not an option, as one need
-lrt, which needs -lpthread, which is problematic to link statically
- pipes: handling the pipes from parent to child of child of child
would be hard to program
- socketpair: should be the same problematic as it's with pipes
- fifos: one would have to create the fifos before and two fifos
for each child; possible, but very unelegant; and one would have
to memorize, which child is connected to which fifo; again possible,
but somehow unelegant
- signaling: one could implement communication with some kind of
morse code with signals, but that won't be a good solution
Questions:
- Is there any way, case b) (socket already existing) can be solved in
a way that I tell bind() to use an existing socket?
- What would be the best solution to talk bidirectional to clients
in this scenario?
I appreciate any hint, as I really like the socket mechanism and would
like to keep it.
Thanks in advance,
Nico

Meta-dependencies,
Nico Schottelius 2005-05-24
--------------------------------------------------------------------------------
1. What are Meta-Dependencies?
2. What are the advantages / disadvantages of it?
3. The solutions
1. What are Meta-Dependencies?
A Meta-depedency describes the type of service another service wants, but
not the exact service.
Example:
remote-services/ssh wants a dns-resolver, it does not care about
what it is (tinycach, bind, maradns, ...), but that it does
name caching.
2. What are the advantages / disadvantages of it?
Meta means beeing indirect. Indirect means beeing slow. So, if
cinit would have to care about meta-dependencies, the code would become
much bigger, bloatig and much slower.
On the other hand, on would perhaps like to use meta-dependencies, if
one tests different services with the same functionality or switches
them dependending on the situation.
3. The solutions
As told above, cinit won't care about meta-dependencies and as you'll see
it does not need to.
The first solution would be to have a mapping table outside of cinit.
This table could be a file for every meta-dependency and contain the
possibilities:
dns-resolver:
remote-services/bind
local-services/tinydns
...
So one would have to call a program, which creates the real cinit
configuration. This is imho not a very elegant solution and could cause
problems, when handling self-written services.
Another possibility is to use symlinks: Create service-directories
for all services beeing installed, but do dependencies in "wants/"
and "needs/" to a symlink (for instance create /etc/cinit/meta
and link to real services in there):
/etc/cinit/meta/dns-resolver -> ../remote-services/bind/

Subject: Bug in TC2-d6 bind - bind a name to a socket
Reply-To: austin-group-l__AT__opengroup.org
Bug report from : Nico Schottelius , cLinux
(Note that the reply-to line automatically redirects
to austin-group-l__AT__opengroup.org for further discussion on bug reports)
@ page 1 line 0 section bind - bind a name to a socket objection {-1}
Problem:
bind should 'assign a name to a socket', but in particular environments it will fail, where it could succeed.
Long Description:
When opening a new socket, with type PF_UNIX
(sock = socket(PF_UNIX,SOCK_STREAM,0);) and one sets
the socket option SO_REUSEADDR
(setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, &tmp, sizeof(tmp))),
bind does not honour this setting.
It is reported on irc channels, that SO_REUSEADDR is only supported on
PF_INET sockets and that's what I would claim a bug.
If a socket exists in the filesystem and no process is bound to
it, bind wail fail anyway.
This is especially problematic, when one is in an environment,
which is pre-startup (like beeing init) and one wants to use
sockets, but everything is mounted read-only.
So, if bind() would honour the option, it would be able
to bind() to a socket, which exists (as creating one on a
read-only filesystem is not possible).
Action:
Proposal:
Add better specification to either socket(7) or bind(2), which
explains the behaviour of bind, when this option is set
or even better: Specify, that bind should take care of this bit,
also when using PF_UNIX.
In general the socket(7) manpage should explain more in detail
or at least reference other documents (unix(7)?), which explain what the
option for a specific protocol does.
