X-Git-Tag: edk2-stable201903~2036
X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=b90c335fbbb674470fbf09601cc522bf61564c30;hp=b90c335fbbb674470fbf09601cc522bf61564c30

NetworkPkg/TlsAuthConfigDxe: preserve TlsCaCertificate variable attributes

If the platform creates the "TlsCaCertificate" variable as volatile, then
EnrollX509toVariable() shouldn't fail to extend it just because
TLS_AUTH_CONFIG_VAR_BASE_ATTR contains the EFI_VARIABLE_NON_VOLATILE
attribute.

Thus, if the variable exists, add the EFI_VARIABLE_APPEND_WRITE attribute
to the variable's current attributes. This is what DeleteCert() does
already.
