Subject: [PATCH] session: support server banners up to 8192 bytes (was: 256)
|
|
|
|
If server had banner exceeding 256 bytes there wasn't enough room in
|
|
`_LIBSSH2_SESSION.banner_TxRx_banner`. Only the first 256 bytes would be
|
|
read making the first packet read fail but also dooming key exchange as
|
|
`session->remote.banner` didn't include everything.
|
|
|
|
This change bumps the banner buffer to 8KB to match OpenSSH.
|
|
|
|
Fixes #1442
|
|
Closes #1443
