           Summary: Connection aborted on large data -R transfer
           Product: Portable OpenSSH
           Version: 4.7p1
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: ssh
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: t8m at centrum.cz


Using SSH port forwarding for mail transfers, large mails abort it.

Steps to Reproduce:
1. ssh -v -t -R 2852:127.0.0.1:852 REMOTE sleep-command
   specifically: ssh -v -t -L 2525:127.0.0.1:25 -R 2852:127.0.0.1:852
-R
2022:127.0.0.1:22 paulina.vellum.cz 'while :;do echo -n .;sleep
1m;done';sleep
1m;done
2. Start transfer at the REMOTE host to port 2852.

Actual results:
local ssh:
debug1: channel 3: new [127.0.0.1]
debug1: confirm forwarded-tcpip
debug3: channel 3: waiting for connection
debug1: channel 3: connected
...debug2: channel 3: window 935334 sent adjust 1161818
debug2: channel 3: window 966656 sent adjust 1130496
buffer_get_string_ret: bad string length 557056
buffer_get_string: buffer error

It seems to be a new regression in 4.7p1.
