[jira] [Created] (SSHD-1287) Use the maximum packet size of the communication partner
Ryosuke Kanda created SSHD-1287:
---
Summary: Use the maximum packet size of the communication partner
Key: SSHD-1287
URL: https://issues.apache.org/jira/browse/SSHD-1287
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 2.8.0
Reporter: Ryosuke Kanda
Attachments: ClientMain.java, ConsoleLog, ServerMain.java
It appears that SSHD may use the maximum packet size presented by the
communicating party to request reception.
RFC 4254 contains the following statement, where "maximum packet size" can be
read as "the maximum packet size that the sender is willing to accept" (as in
"initial window size").
{code:java}
Section 5.1 Opening a Channel
The 'maximum packet size' specifies the maximum size of
2an individual data packet that can be sent to the sender.{code}
The client/server must comply with its own declared maximum packet size.
I encountered this issue when I was using "freeSSHd" as an SFTP server.
The version of freeSSHd is 1.3.1.
The event is confirmed by creating a server with SSHD.
Attached are the client and server sources, as well as the client debug logs
(up to the first read request).
When communicating with these, the client knows that its maximum packet size is
"32768" and the server's maximum packet size is "65536".
{code:java}
// client window
[main] DEBUG org.apache.sshd.common.channel.Window -
init(Window[client/local](SftpChannelSubsystem[id=0,
recipient=-1]-ClientSessionImpl[user@localhost/127.0.0.1:10022][sftp]))

size=2097152, max=2097152, packet=65536 {code}
And when requesting to receive a file, it requests to read 65536 bytes at a
time. This means that it attempts to receive packets that exceed 32768 bytes.
{code:java}

I hope this report is helpful.

Ryosuke Kanda commented on SSHD-1244:
-
> Don't know what is meant by "INT_MAX", but Integer.MAX_VALUE is 2^31-1.
Thank you. Update the title.
> This seems to be a violation of [RFC4254 - section 5.2]
As mentioned above, "INT_MAX" refers to 2 ^ 31-1 which is the maximum value of
int type that is not unsigned.
Therefore, I think it is a problem that we cannot receive a value that exceeds
this (and does not exceed 2 ^ 32-1).
> How do you know that this is the reason for the failure ?
As added to the description.
What should I do if I need a complete debug log?
> BTW, what does ProFTPD have to do with SSHD ?
Earlier, there were reports that our product (using SSHD) could not communicate
with ProFTPD.
This product is currently about to switch to the newer SSHD.
As a result of switching, we are checking whether the problems that occurred in
the past will be improved.

Ryosuke Kanda updated SSHD-1244:
Description:
If the new window size specified by SSH_MSG_CHANNEL_WINDOW_ADJUST exceeds
INT_MAX, it will not be recognized correctly.
I think the cause is in the following places:
org.apache.sshd.common.channel.Window.expand（int）
I am doing machine translation, so please allow it to be unnatural.
I encountered this issue when I was using ProFTPD as an SFTP server.
The version of ProFTPD is 1.3.5e.
The SFTP feature of ProFTPD notifies 2 ^ 32-1 bytes as the initial window size
by default.
I've confirmed that SSHD can handle this without any problems, so I sent a 4GB
file to see what happens when Window Adjust is done.
As a result, a Window Adjust was done and SSHD was unable to handle this
successfully.
I have attached the client implementation to this issue.
(Maybe a poor implementation ...)
The console logs, including the debug logs, were too large to attach.
The parts that are clearly set for the SSH client are as follows.
ServerKeyVerifier
HostConfigEntryResolver
KeyIdentityProvider
In the log, the part where the error occurred is as follows.
You can see that SSHD recognizes the new Window size as a negative value.

I encountered this issue when I was using ProFTPD as an SFTP server. The version of ProFTPD is 1.3.5e. The SFTP feature of ProFTPD notifies 2 ^ 32-1 bytes as the initial window size by default. I've confirmed that SSHD can handle this without any problems, so I sent a 4GB file to see what happens when Window Adjust is done. As a result, a Window Adjust was done and SSHD was unable to handle this successfully. > Client fails window adjust above Integer.MAX_VALUE > -- > > Key: SSHD-1244 > URL: https://issues.apache.org/jira/browse/SSHD-1244 > Project: MINA SSHD > Issue Type: Bug >Affects Versions: 2.8.0 >Reporter: Ryosuke Kanda >Assignee: Lyor Goldstein >Priority: Minor > > If the new window size specified by SSH_MSG_CHANNEL_WINDOW_ADJUST exceeds > INT_MAX, it will not be recognized correctly. > I think the cause is in the following places: > org.apache.sshd.common.channel.Window.expand（int） > > I am doing machine translation, so please allow it to be unnatural. > > I encountered this issue when I was using ProFTPD as an SFTP server. > The version of ProFTPD is 1.3.5e. > The SFTP feature of ProFTPD notifies 2 ^ 32-1 bytes as the initial window > size by default. > I've confirmed that SSHD can handle this without any problems, so I sent a > 4GB file to see what happens when Window Adjust is done. > As a result, a Window Adjust was done and SSHD was unable to handle this > successfully. > > -- This message was sent by Atlassian Jira (v8.20.1#820001) - To unsubscribe, e-mail: dev-unsubscr...@mina.apache.org For additional commands, e-mail: dev-h...@mina.apache.org
