Scikit-learn GLM models

As per Scikit-learn's documentation, the `LogisticRegression` model is a specialised case of GLM, but for `LinearRegression` model, it is only mentioned under the OLS section. Is it a GLM model too? If not, the models described in the sub-section "Usage" of section "Generalized Linear Models" are GLM?
