smbclient hangs in interactive mode after readline: 8.2.13 -> 8.3

Hi All,

Our team found smbclient hangs in interactive mode after readline: 8.2.13 -> 8.3

When downgrade readline to older : 8.2.13, everything works fine.

Here “hang” means “terminal accepts no input after login”

Reproduce steps:

  1.  Add samba to core-image-minimal



diff --git a/meta/recipes-core/images/core-image-minimal.bb b/meta/recipes-core/images/core-image-minimal.bb

index 84343adcd8..661d6ca904 100644

--- a/meta/recipes-core/images/core-image-minimal.bb

+++ b/meta/recipes-core/images/core-image-minimal.bb

@@ -1,6 +1,7 @@

SUMMARY = "A small image just capable of allowing a device to boot."



-IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL}"

+IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL} samba“



  1.  $ runqemu core-image-minimal snapshot nographic
  2.  $ cat /etc/samba/smb.conf

[global]

   workgroup = MYGROUP

   server string = Samba Server

   security = user

   hosts allow = 192.168.2.16

   load printers = yes

   log file = /var/log/samba/log.%m

   max log size = 50

   interfaces = localhost

   dns proxy = no



[test]

   comment = samba server

   path = /home/test/samba

   writable = yes

   browseable = yes

   guest ok = yes

   public = yes

  1.  systemctl restart smb
  2.  root # smbclient //192.168.2.16/test -N
       Try "help" to get a list of possible commands.
      smb: \>

The current Samba version appears to have compatibility issues with the newer readline library.
However, upgrading to the latest stable release (4.22.4) introduced multiple build errors that are beyond my current troubleshooting scope.

I'm reaching out to the community for assistance. Does anyone have proven solutions or workarounds for this issue?

By any chance, have you tried this patch[1] with readline?
Someone reported[2] a very similar issue with the latest release of
readline, and this patch was the result.
