Subject: [CIFS] Re-enable Lanman security
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20d1752f3d6bd32beb90949559e0d14a0b234445;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[CIFS] Re-enable Lanman security

commit ac68392460ffefed13020967bae04edc4d3add06 ("[CIFS] Allow raw
ntlmssp code to be enabled with sec=ntlmssp") added a new bit to the
allowed security flags mask but seems to have inadvertently removed
Lanman security from the allowed flags. Add it back.
