This has introduced a regression that I'm seeing when running `ls` on
some network shares. I can reproduce the behaviour with an install of
only the base Cygwin packages, and the behaviour disappears if I
downgrade back to v2.8.0-1.
(Apologies for the obfuscation in the below report; I'm not clear on
what I'm authorised to disclose about my work network, and so erring
on the side of caution.)
Specifically, if I run `ls -l` or `ls --color=always` over certain
directories on one of my company's Windows network shares, I sometimes
see errors stating:
ls: cannot access '//path/to/file/in/listed/share': Bad address
The file that is listed in the error message appears as below in the
`ls -l` output:
-?????????? ? ? ? ?
? <filename>
When this happens, the file is also coloured by `ls` as if it were not
executable; with v2.8.0-1 the file is correctly marked as executable.
Alternatively, in some circumstances when `ls`ing that directory, I
see no output whatsoever. This seems to happen in particular when
accessing the directory via a two-hop symlink, i.e. something created
like this:
$ ln -s //path/to/share symlink1
$ ln -s symlink1 symlink2
$ ls -l symlink1/
<list of files>
$ ls -l symlink2/
$
The behaviour doesn't seem to be entirely consistent, and I haven't
been able to characterise when this behaviour occurs and when it
doesn't, even on the same directory.
Given the behaviour seems to reliably not occur when running a bare
`ls`, I'm guessing the problem is relating to how Cygwin is parsing
the file permissions.
I've attached redacted `cygcheck -srv` output.
Cheers,
Adam

I have not been able to reproduce this. The only relevant changes in
2.8.1 in terms of `ls' were related to reparse points (native symlinks,
directory junctions, etc) and a change of st_blocks computation related
to CompactOS compression.
For a start, can you please check if you can reproduce the problem
with the devolper snapshot from 20170606?
Also, can you reproduce this with 2.8.1 under strace perhaps? If so,
I'd be interested to see the strace output. If you fear to compromise
company data, we can arrange to do this in private email.
Thanks,
Corinna

After several false starts (including Windows getting very upset about
*something* to do with moving DLLs around and blue screening on me), I'm
not seeing this behaviour with the 20170606 snapshot.

I have the strace output from both the successful and unsuccessful
cases; the failing case on v2.8.1 appears to be going wrong at the
following exception, which appears to be the first significant
difference between the two strace outputs:
47 268130 [main] ls 16232 stat_worker: (\??\UNC\<path>, 0x84, 0x180318898), file_attributes 2592
--- Process 16232, exception c0000005 at 000000018012f3cd
If you can give me your private email address, I'll send the full strace
output over.
Thank you!
Adam
