Subject: [CIFS] Turn off Unicode during session establishment for plaintext authentication
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c76da9da1fffa6de263486df54950eb328d58f71;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[CIFS] Turn off Unicode during session establishment for plaintext authentication

LANMAN session setup did not support Unicode (after session setup, unicode can
still be used though).

Fixes samba bug# 5319
