Bug 806862

Description of problem:

When transferring really large files with curl scp:// the connection is not closed. This seems to be related to key re-exchange - bugs 804145, 804145.


Version-Release number of selected component (if applicable):
libssh2-1.2.2-7.el6_2.3

How reproducible:
always for me

Steps to Reproduce:

1. To reproduce use the patch openssh in a way mentioned in Bug 804145#c1. The patch is a bit different for RHEL6.2 openssh and has to be "ported", also you can use >>=10 instead of >>=5 to speed up requests for new key.

2. Prepare ssh keys for current user 
3. Execute patched sshd on a different port (or instead of running sshd)

# /path/to/patched/sshd -p 2048 -f /etc/ssh/sshd_config -d &

4. initialte a download of large file (so the keys are re-exchanged during the download, can be seen in sshd debug messages)

$ curl -v -u username: --key ~/.ssh/id_rsa --pubkey ~/.ssh/id_rsa.pub
scp://127.0.0.1:2048/tmp/file -o /dev/null

The bug can be reproduced when transferring from localhost, not from other host
(for me).

  
Actual results:
connection not closed when the file is transferred

Expected results:
connection is closed
