[ANNOUNCEMENT] New on sourceware: autoconf-stable-2.13-4
The autoconf-stable package has added to the cygwin distribution. It contains autoconf-2.13, installed into /usr/autotool/stable. This addition is part of a large restructuring of the autotools. See the message posted to cygwin-announce on 2001-12-02 entitled Restructuring the automake and autoconf packages for a full description. To update your installation, click on the Install Cygwin now link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Save it and run setup, answer the questions and pick up 'autoconf-stable' from the 'Devel' category. You may need to click the Full button if it doesn't show up. You might want to make sure you update/install ALL of the following six packages: autoconf autoconf-stable autoconf-devel automake automake-stable automake-devel Note that downloads from sources.redhat.com (aka cygwin.com) aren't allowed due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Japan, ftp://ftp.u-aizu.ac.jp/pub/gnu/gnu-win32/ is already updated. In DK, http://mirrors.sunsite.dk/cygwin/ is usually up-to-date. If one of the above doesn't have the latest version of this package you can either wait for the site to be updated or find another mirror. Please send questions or comments to the Cygwin mailing list at: [EMAIL PROTECTED] . If you want to subscribe go to: http://cygwin.com/lists.html I would appreciate if you would use this mailing list rather than emailing me directly. This includes ideas and comments about the setup utility or Cygwin in general.

Updated: cygrunsrv-0.94-2
I have updated cygrunsrv to version 0.94-2. It fixes an error in storing the working directory in the registry when the `--chdir' option has been used. To update your installation, click on the Install Cygwin now link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions.

I am aware of mount under cygwin but the mount is not exported to Windows. I have checked if it makes sense using reparse points for symlinks once when W2K was new. We had to reject using them since they are not as flexible as we need it to get POSIX symlinks. Main reason is that they have to be absolute windows paths. So they would have to be changed each time the mount table is changed in a way which would influence them. Many POSIX symlinks are relative links to their target. That's completely impossible. And reparse points to files aren't supported at all. A couple of comments: I agree the MS implementation is not flexible. However, if the reparse points do not cross file systems, I believe they can be relative. I do this now and again.. C:\some\dir\here\and\there\ linkd otherdir ..\..\otherdir Linkd takes a relative path as argument but it's translated into an absolute path before storing it in the reparse point. The crappy part about the MS implementation is there doesn't seem to exist an easy way to obtain the link destination. There's no 'ls -l' equivalent. It's no problem to read the reparse point content so a Cygwin implementation would have given that information. No, reparse points are not useful for a POSIX emulation layer. Sure, it would be possible to add code to Cygwin which allows to treat reparse points as symlinks but I'm not going to do that in the near future and I'm not as interested in them as I was in early 2000. At least it would again slow down the symlink evaluation code (the third method to look for). However, if somebody wants to contribute code... You're right about reparse points not working with files, but hardlinks solve that issue. I was thinking in pseudo code: -s flag given: if src == directory create_junction() else create_shortcut() endif But hardlinks are a completely different thing. And they are actually supported in Cygwin for years on NTFS. FAT can't have hardlinks.

Subject: Re: bash/cmd CTRL-C problem...
Hi,
sorry for following up myself, but I found out that Cygwin equally handles
CTRL-BREAK and CTRL-C by sending a SIGINT to the process.
See http://groups.yahoo.com/group/gnu-win32/message/27643 (last sentence).
This seems to be the source of the problem.
CTRL-BREAK under the cmd shell terminates the process after handling the
signal without further executing any code. The bad thing is that under
bash
the same behaviour follows from pressing CTRL-BREAK _and_ CTRL-C !!
If this is a design issue, can someone please explain what the reasons
are...
We have an application that forks other processes. The main thread is
waiting for the signal handler to return in order to cleanly stop the
child
processes. By just stopping the parent process the child processes keep
running and I have to kill them manually each time I press CTRL-C. The
same
application is working fine under windows cmd shell and bash under Linux ,
HP-UX 10/11, AIX4.x, and SunOS 2.5+...
Please help, I don't want to use the stupid windows cmd shell ;-)

Subject: bash/cmd CTRL-C problem...
Hi,
I'm new to the list and I don't know if this problem is already solved,
but
I couldn't find a hint neither on the archives nor on the FAQ or
somewhere
else on the net.
My problem is related to bash/cmd and signal handling.
In my app I installed a signal handler for SIGINT. The app is going into
a
wait loop and waiting for the exit flag from the signal handler to be
set.
When pressing CTRL-C in the windows cmd shell the application continues
normally after the signal handler has been caught. Under bash the signal
handler is also correctly called, but after that the app is exiting
immediatly, i.e. not continuing with the code.
Here is the source:
/
#include windows.h
#include stdio.h
#include signal.h
bool loop = true;
extern C void signalHandler(int sig)
{
switch( sig )
{
case SIGINT: // == 2
printf(SIGINT=%d\n,sig);
break;
default:
printf(default=%d\n,sig);
break;
};
loop=false;
}
int main(int argc, char* argv[])
{
if (signal( SIGINT , signalHandler ) == SIG_ERR)
return -1;
printf(### ctrlbreak: Waiting now...\n);
while(loop)
Sleep ((DWORD) 1000) ;
printf(### ctrlbreak: Finished waiting now...\n);
return 0;
}
/
Here the the output of the app under Win2K/bash:
// bash2.05a-2
$ ./ctrlbreak.exe
### ctrlbreak: Waiting now...
SIGINT=2
// GNU bash, version 2.02.1(2)-release (i586-pc-cygwin32) B20.1
bash-2.02$ ./ctrlbreak
### ctrlbreak: Waiting now...
SIGINT=2
// cmd.exe Win2k SP2
### ctrlbreak: Waiting now...
SIGINT=2
### ctrlbreak: Finished waiting now...
You can see that under the cmd shell the text Finished waiting now...
is
printed which does not come out under the bash. The app is not linked
against any cygwin library. It is a plain VC++ console application. But
when
I compile with gcc from the cygwin package I have the same result.
Any hint would be greatly appreciated...
Michael
PS: I just downloaded the latest stable version 1.3.6 today...

But that's ok. Only privileged accounts need to access the account rights to create a token. I've found the following KB article: HOWTO: Manage User Privileges Programmatically in Windows NT (Q132958) I am also mind boggled by the behavior of setuid() running under cygrunsrv. Base case: user xxx runs program prog from the shell without admin (but with CREATE_TOKEN) privs. prog does setuid(y). That fails, which is consistent the previous paragraph. case 1: cygrunsrv -I ... -u xxx -p ...prog setuid(y) fails, as expected. case 2: cygrunsrv -I -p ...prog prog notices it is SYSTEM and setuid(xxx). That works as expected. Now running as xxx, setuid(y) succeeds! It looks like prog has inherited unexpected rights from SYSTEM... Uh, that's a problem, perhaps. The setuid() code is doing the following currently: sid = getsid(uid) RevertToSelf(); token = create_token(sid); ImpersonateLoggedOnUser(token); Important here is the call to RevertToSelf() which always restores all privileges of the original account who started the process. This is only eliminated after an exec which substitutes the process by a new process which is created using CreateProcessAsUser(token). The privileged process will always keep it's privileges since it's always able to RevertToSelf. While I am at it, here is another weird observation: base case above: prog reads some registry key. Succeeds. cases 1 and 2: prog reads some registry key. Access denied. But if xxx has admins privilege, prog can read the registry in cases 1 and 2... Can this be explained somehow? It's all on a standalone Win2000. Hmm, some debgging would help here, perhaps.

This could be a difference, because I have found that before binding an unlink() is made, but fails. The usual Win32/Posix difference: You can't unlink a file on Win32 which is still in use.

[ANNOUNCEMENT] Updated: login-1.4-3
I have updated the version of login(1) to 1.4-3. This version fixes the problem that login has been using the wrong path to the `lastlog' file. It now uses /var/log/lastlog as sshd does, too. I've additionally tweaked /usr/doc/Cygwin/login.README slightly to accommodate experiences with posting on [EMAIL PROTECTED] For a brief descripton of what this package is and what it contains, see http://cygwin.com/packages/ . To update your installation, click on the Install Cygwin now link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. Note that we do not allow downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours. If one of the above doesn't have the latest version of this package then you can either wait for the site to be updated or find another mirror. The setup.exe program will figure out what needs to be updated on your system and will install newer packages automatically.

The situation is that I would like to run cron on my desktop and by extension allow my users to run their own crons on their desktop. We're in a domain and as such we have set it up such that people's home directories are mounted on /home from the Windows server that houses the home directories. Therefore we have the following mount: \\sonscentral\users on /home type system (textmode). Given my username, adefaria, therefore ls /home/adefaria (or ls ~) will list the contents of \\sonscentral\users\adefaria. Note there are no mapped drives here, just UNC names. Anyway, cron has no access to them. It's running under SYSTEM account which has only access to publically available net drives, that is, drives which are available w/o any form of authentication required. The forked cron jobs are running in the same logon session even if they are running under another user account. Keep in mind that the user context has been changed w/o asking for logon credentials. This is different from what the native Windows scheduler does (which requires entering the password). No credentials, no authenticated network drive access. That's it.

Now think of a file which is coincidentally exactly 1 page long... - use .exe extension detection consequently in all syscalls You mean unlink() etc.? - automatically add the .exe extension to a newly created file on close() when the first four bytes are 0x4d, 0x5a, 0x90, 0x00 (MS Executable magic bytes) and the file name didn't have an extension already. (This is from UWIN, I think it's really nice). Ugh. I'm not quite sure if I like that. - exec*() functions would always invoke a /bin/sh on a file that isn't a valid executable. Only execlp()/execvp() should do so, others must return with an ENOEXEC. Sounds like a bug. - the exec*() fix revealed a bug with vfork() in ash We have some vfork() changes in the meantime and even ash had an related error which should be fixed. - use the contents of $SHELL instead of /bin/sh for execvp()/execlp() and system() (with some additional checks, e.g. do not use a csh, use only 'trusted' shells from /bin, /usr/bin, /usr/local/bin etc.). This allows the user to select his favorite shell manually, so no more copy /bin/bash to /bin/sh troubles. (This is also from UWIN). Hmm, interesting idea... - some mmap() problems have been fixed. Since I have changed so much in mmap() you should actually first compare your changes to the current version. - utime() doesn't mark st_ctime for update Really? I would never think so when inspecting the source code. Does this sound OK for you, especially the UWIN things I'm mimicing? I don't like the idea to append a .exe suffix related to the first bytes in the file. But we can discuss everything, of course.

If a file is, say, 8190 bytes, then we have a two page map, size 8192. So we have two trailing 0 bytes. If getpagesize() returns 4096, gcc can count that correctly, if getpagesize returns 65536, gcc assumes 57346 trailing bytes. No problem, gcc only accesses exactly one trailing 0 byte. If the file is 8192 bytes long, mmap maps exactly 8192 bytes, no trailing bytes left. If getpagesize() returns 4096, gcc knows that, if getpagesize returns 65536, gcc assumes 57344 trailing bytes.

Does any user have an uid == 0? If not then it does not matter anyway. I can just leave it as it is. If in future some superuser concept might find it's way into Cygwin, this $SHELL stuff is safe already. The problem is that by default the Everyone group has the uid and gid 0. The user can change that in the passwd and group files. You just should stick with uid/gid 18 for the user SYSTEM. Are you familar with the NT security concept?

The .suffix implies that the user knows what she's doing. rename(a.exe, b): The .exe suffix implies that the user knows what she's doing, too, so a.exe is renamed to b This also holds for link(). I've taken that from UWIN, too. Yup, that sounds reasonable to discuss. One general question, though. How do these changes to handle things like U/WIN collide with the propietary U/WIN license?

Let f be the size of a file gcc is mmaping. 1) Gcc can't handle a remainder of m divided by f that is greater than some number between 2 and 57346. 2) If the remainfer of m divided by f is 0, gcc behaves correctly. 3) If f m, then gcc assumes that f is m bytes long? Sounds to me like gcc is badly broken. i.e. in your prior example: where m = 4096 if the file is 2048 bytes long, mmap maps exactly 2048 bytes. No, it maps 4096 bytes since memory maps always use chunks of the pagesize which is 4096 on Win32. if m is 4096, gcc assumes there is 2048 trailing bytes. Now it is a problem, since the one trailing 0 byte doesn't exist. Segmentation fault. IOW, I don't see how the 4K vs 64K thing affects this scenario, it seems to be driven purely by the fact the m != 1. Sorry but you didn't understand or I don't understand your above reasoning which is likely. GCC isn't broken (from the gcc's engineers point of view) but it's using a property of mmap: mmap always maps whole pages and the trailing unused bytes in a mmap'd page are always zeroed out. This fact is used for some sort of speed up when reading header files. IMO that's ugly but... Anyway, gcc reads a C header file just as a string with trailing 0. For that reason gcc has to know the pagesize of the system, returned by getpagesize(). If the file size is not exactly a multiple of the pagesize, you always have a trailing zero so gcc can use the above method. If a file has no trailing 0 byte (which would happen very seldom) gcc would have to fallback to another method (I do know nothing about). Now, the pagesize on Windows is 4K. If the file size is coincidentally 4096 or 8192 or any other multiple of 4K, gcc knows that it has to fallback to it's slow method since getpagesize() has returned the correct value. If we change getpagesize() to return the granularity (64K) instead of the pagesize, gcc would wrongly assume that the file doesn't exactly match the pagesize so it would assume that it can use the fast method and would expect a trailing 0 byte.

When one uses POP or IMAP to retrieve email one must authenticate one's username and password to the server to retrieve the email. Therefore somewhere the username and password is stored. For example, when using POP with Netscape to retrieve email from a mail server, Netscape stores the username and password somewhere (a configuration file or the registry). For security, Netscape encrypts the password in some fashion before storing it. When needed Netscape retrieves this information, unencrypts it and sends it along to the mail server so that the user is authenticated and the email is retrieved. Why then can't Cygwin's cron do something similar? Perhaps because I don't get compensation for it. I *am* working on Cygwin as a volunteer as everyone else and I'm sorry to say that, I'm actually not interested in your problem with cron. It works for me.

I've updated the version of OpenSSH in cygwin/latest to 3.0.2p1-4. This version contains a backpatch from the current CVS version of OpenSSH, which allows to run OpenSSH with newer releases of the OpenSSL libraries without having to rebuild the OpenSSH package. To update your installation, click on the Install Cygwin now link on the http://sources.redhat.com/cygwin web page. This downloads setup.exe to your system. The, run setup and answer all of the questions. Note that we do not allow downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours.

Re: openssh issue with UID's over 65535
On Mon, Jan 14, 2002 at 08:12:00PM -0500, Mark Bradshaw wrote: I have an issue with openssh and UID's over 65535. Similar things were discussed a bit back, but this is slightly different. Seems that sshd will die when a user with a UID too high logs in. The root cause of this is cygwin's use of an unsigned short for uid_t, instead of an integer. As the UID goes through the ssh server, session.c calls get_last_login_time (sshlogin.c) with an integer variable. When it hits get_last_login_time, however, it's squashed into a uid_t, which is too small for it. The uid changes and problems occur. I'm guessing it wouldn't be too swift to just change the definition in types.h. That oughta break lotsa stuff. Is there some clear path to getting uid_t changed to an int, or is there a different/better fix for this? Change the UIDs in /etc/passwd to be smaller than 65536. Changing uid_t to unsigned int would break almost all Cygwin applications. We wouldn't be backward compatible. We can't do this. At least at this point. I would expect some more really interesting changes in Cygwin before breaking backward compatible.

I've updated the version of OpenSSL in cygwin/latest to 0.9.6c-3. The version 0.9.6c-2 had a syntax error in the csh startup file /etc/profile.d/openssh.csh. Another fact I forgot to mention in my announcement of 0.9.6c-2 was that the binary package is build without support for the cryptographic algorithms IDEA, RC5 and MDC2. These three algorithms suffer patenting issues in some countries which disallow usage w/o a fee. If you're not affected by that and you're abslolutely sure to need these algorithms, you'll have to rebuild the OpenSSL DLLs from the source archive.

Hmm, noticed. That shouldn't be too hard to add. 1) If setuid(gid) with a gid that doesn't exist, the system silently sets the gid to administrators. That is not fail safe! The problem is that getgrgid() never fails. It should have a flag to tell it whether it should default or not. [The default is fine when specifying a SET_ACCESS ACE] Yes, that's true. That's the typical fallback for unmaintained passwd and group files. We should probably add a function for internal access which never returns the fallback. 2) my_token isn't closed in create_token() Thanks for the hint! I applied a patch. 3) Why is it necessary to set the PrimaryGroup in the process token in setegid()? (That can fail silently). Is that field ever read? I thought that PrimaryGroup only needs to be set in impersonation tokens, so that seteuid() can decide if an existing token can be reused. No, the primary group is used also to create object DACLs. When setting the PrimaryGroup, even native Windows child processes create file with that group as creator group instead of the default group (e.g. always None, 513 on standalone machines). 4) If in cygrunsrv -u user ... the Cygwin and Windows user names differ, then the process will have the wrong uid.

What bothers me is that the call may fail silently (e.g. if The problem is that in contrast to POSIX the PrimaryGroup is restricted to the Groups already listed in the access token of the process. So it will fail if the primary group is set only for a later impersonation. But that shouldn't matter then, IMO. setgid() is called while impersonation is in effect, access to the process token would probably be disallowed). Even if the call succeeds, won't Windows use the thread (impersonation) token rather than the process token when creating DACLs? I'm not quite sure if I understand. If the setgid() is made while a impersonation is active, the setgid() should affect the impersonation token. That seems to be correct. Changing the PrimaryGroup in that token shouldn't affect the ability to RevertToSelf(). Wouldn't it be safer to always rely on myself-gid to set ACLs and only use the PrimaryToken to verify if an existing token can be reused? Good question. However, I don't think it's unsafe to change the primary group. If it was successful, further securable objects are created using the correct primary group. If it wasn't successful, nothing has changed, nothing got worse. Oh, btw., you're perhaps interested to contribute to Cygwin code? Anything specific in mind?
