Hi,
I've just dropped snapshot 2014-05-05 into my 64bit Cygwin install.
I am getting a segmentation fault running ssh from within a screen
session. Regardless of the arguments passed:
$ ssh -V
OpenSSH_6.6.1p1, OpenSSL 1.0.1g 7 Apr 2014
$ screen
<cleared screen>
Screen version 4.01.00devel (GNU) 2-May-06
...
[Press Space or Return to end.]
<cleared screen>
$ ssh -V
Segmentation fault (core dumped)
I've attached the stackdump file, as well as cygcheck,out.
--
Thanks,
Shaddy

The problem, which I totally not realized since I started implementing this stuff is, that by propagating this cache to child processes, said child processes suffer from what the parent process does to the passwd structures in the cache. Screen seems to call getpwuid and then sets some of the pointers in the passwd structure it got from the call to NULL, apparently for some sort of security, this way overwriting the cached passwd struct for the current user. Ssh on the other hand tries to copy the passwd structure, but it never checks for NULL pointers because, well, the passwd structure never contains NULL pointers. This annihilates every advantage the cygheap caching has. *sob* Oh well, back to the drawing board. This will take some time, though.

Caching still sounds correct, let's fix the bug in screen instead of bloating cygwin to work around it. Or maybe find a way to cause a SEGV in any process that tries to write into the pointer returned by getpwuid and friends, to help them realize their bug, rather than the current state of propagating the broken memory to other processes. Maybe you just memcpy the result out of the cache into local memory, instead of returning a pointer into the actual cygheap cache. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 604 bytes --] ^ permalink raw reply [flat|nested] 9+ messages in thread

Oh, wow. However, what if screen (thinks it) never calls getpwuid or getpwnam again. In that case it may do whatever it wants with the pointers inside the returned passwd structure, doesn't it?

Yes, that's what I was coming to realize, too. I'm going to copy the entire entry to local storage and return a pointer to that.

This suggests that the behavior could be modeled by a regular account log in, immediately followed by a chgrp which is dependant on the type of regular account, or some other variation of su and chgrp actions.

Fixing this would be well out of my depth, but I'll gladly include any patches to screen that fix it. Meanwhile there's a new release of screen (4.2.1) upstream, about one year newer than the last commit I packaged for Cygwin, so maybe this problem has already been addressed. I'll get the new release out ASAP so we can test.

Never looked into the sources, but if you see something along the lines of pw_passwd = NULL; it's what I observed. > Meanwhile there's a new release of screen (4.2.1) upstream, about one year > newer than the last commit I packaged for Cygwin, so maybe this problem has > already been addressed. I'll get the new release out ASAP so we can test. For testing, please keep in mind to test with the latest snapshot showing the problem. That would be the 2014-05-05 snapshot.
