git clone fails with: error: chmod on config.lock failed: Invalid argument

git clone fails with: error: chmod on config.lock failed: Invalid argument

[Rainer Blome]

Hi!

When I use "git clone foo bar" on a Linux host, it works as expected.

 git clone foo bar
 Cloning into 'bar'...
 done.

When I use the same command on my Cygwin 64 installation, this used
to work, but does not work any more.  I can fetch and otherwise use
Git in existing repos all right (have not noticed anything else
amiss), but the clone command fails like this:

----
cd /cygdrive/c/base
git clone foo bar
Cloning into 'bar'...
error: chmod on /cygdrive/c/base/bar/.git/config.lock failed: Invalid argument
error: chmod on /cygdrive/c/base/bar/.git/config.lock failed: Invalid argument
error: chmod on /cygdrive/c/base/bar/.git/config.lock failed: Invalid argument
error: chmod on /cygdrive/c/base/bar/.git/config.lock failed: Invalid argument
error: chmod on /cygdrive/c/base/bar/.git/config.lock failed: Invalid argument
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
----

Directory `bar` exists neither before nor after the attempted cloning.
In the parent directory, manually creating a subdirectory works as
expected:

 /cygdrive/c/base> mkdir bar; ls -ld bar; rmdir bar
 drwx------+ 1 username 123 0 Jan 27 13:13 bar

The issue is not restricted to local cloning, the same messages are
printed when I attempt to clone from a remote host (from which I
can clone just fine from a Linux client).

Searching the internet for "cygwin git error chmod on config.lock
failed: Invalid argument" gave not useful results.

I first noticed the issue after having upgraded to Cygwin 2.4.0-1.
Juding from the directory creation times in `base`,
it looks like the last successful clone happened on 2015-07-28.
I do not know which version of Cygwin I used at that time,
I update roughly once a month.

Today, I upgraded to 2.4.1-1, the issue persists.

I tried downgrading git from 2.7 to 2.6 via the installer.
The issue persisted, so I rolled forward again, the issue persisted.

How can I troubleshoot this further?

Rainer

There might be a problem with the default ACL on the directory 
/cygdrive/c/base.  What does 'getfacl /cygdrive/c/base' show?

Also, what does the native windows icacls command print for that
directory?  The setup of the ACL may give us a hint why git apparently
fails to create the bar subdir.

[Christopher Cobb]

Or maybe chmod is broken, like it is on my machine:

$ touch x
$ chmod 777 x
chmod: changing permissions of ‘x’: Invalid argument

Can you please send the icacls output of the current directory and
the icacls out for the file x?

Rainer, please make sure your mailer doesn't break threading.  I tweaked
the "In-Reply-To" now to return to the original thread on the mailing
list.  Thank you.

Can you please run the same again under strace, e.g.,

  $ strace -o git.trace git config user.email myusername@xyz.org

and send the git.trace file?

Also, please send the icacls output for the directory "bar" and the
directory ".git".

What's weird here is the EINVAL error.  I can't reproduce this on
my machine yet, but if I get more info I might be able to do so.

It's not a permission problem per se.  There's no "Permission denied"
message, just an "Invalid argument".  I just fail to see why this
happens...

Also, an strace of chmod, e.g.

  $ strace -o chmod.strace chmod 777 x

might be helpful.  Please send the file chmod.strace with your reply.

git clone fails with error chmod on config.lock failed: Invalid argument

Hi

I got error  chmod on config.lock failed: Invalid argument and I was 
able to catch the strace. It is attached.

I had a suspicion to locales, but with the <code>LC_ALL=C chmod 777 
x</code< fails too.

Use CC: to my email address for any questions or requests for testing. 
I'm not in the mailing list.

What I see from the strace, chmod fails to request group information:

299755  597014 [main] chmod 5840 internal_getlogin: group not found in group DB

So it looks like either your /etc/passwd or your /etc/group file is
broken.   The new account handling is a bit more sensitive to broken
passwd and group files.  For more information on the changes in account
handling see https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping

For a start, just move both files out of the way, stop your Cygwin
processes and try again.

Re: git clone fails with error chmod on config.lock failed: Invalid argument

Hi

My passwd and groups files got automatically renamed. I can't identify 
the exact date. Last update of cygwin I did yesterday, but the rename 
could happen a long time ago.

 >pwd
/etc
 > ls  passwd* groups*
passwd.backup groups.backup

 > groups
groups: cannot find name for group ID 10749228312
10749228312 ZTB+Group(513) Administrators Users ..... ZTB+Group(1298252)...

ZTB is my AD domain. Seems that any of the groups that I have assigned 
on the domain level was not resolved.

In the old groups.backup there is a record:
None:S-1-5-21-4091695911-3229423371-1046061999-513:513:

BTW: My machine is Windows Server 2008, yesterday I also run the Windows 
update procedure before I notified the chmod error.
A months ago, I had to migrate to the new AD account. The cygwin was 
installed using my old account, which is deleted now. Is it possible 
that the query to AD runs under my old account?

Yeah.  Group 513 on the AD level is the group "Domain Users" which should
always exist.  It looks like all LookupAccountSid requests to your primary
machine domain fail for some reason.

This is group 513 of the local SAM.  This is not related.

That's a good question.  The problem is that I can't see *why* the
requests fail.  This bugs me since failing LookupAccountSid calls should
result in a debug message when running strace.

Do you have changed your /etc/nsswitch.conf file by any chance?

Would you mind to create strace output of the command `id'?


Thanks,
Corinna

No I did not. All lines are commented out there.

Thanks.  It's not helpful, unfortunately.  The only hint that something
is going wrong is the same message as with chmod:

  internal_getlogin: group not found in group DB

There's no other strace message even remotely related to account mapping.
I don't grok that.  There should really be some error message :(

Btw., what's the output of `id'?

I'm wondering... is it possible that LDAP access to your DCs is
restricted?  

Also, can you change /etc/nsswitch.conf like this:

  db_enum: cache local primary

(see https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch-enum)

exit and restart your shell and call `getent group'?  What does it
print?  Are the AD accounts enumerated and what info is printed for
them?  Examples are sufficent, I don't need your entire AD DB :)

Also, what does `getent passwd $USER' print?

Hi

Trying to modify the /etc/nsswitch.conf , I found that I can't write it 
! The file is writable only by the user which created it and which not 
exists any more (see above my story). I changed owner and access rights 
for /etc/nsswitch.conf and whole /var directory tree (also /var/cache).  
And it's started working!

Then I removed the modifications of the /etc/nsswitch.conf (all lines 
commented)  and it works too. It seems that the problem is related to 
file access rights to /var.

Tomas

Weird.  Cygwin doesn't use /var by itself.  Only applications do.
But, anyway, I'm glad you could fix it.
