+Subject: drbd: Fix five use after free bugs in get_initial_state
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Lv Yunlong <lyl2019@mail.ustc.edu.cn>
+
+[ Upstream commit aadb22ba2f656581b2f733deb3a467c48cc618f6 ]
+
+In get_initial_state, it calls notify_initial_state_done(skb,..) if
+cb->args[5]==1. If genlmsg_put() failed in notify_initial_state_done(),
+the skb will be freed by nlmsg_free(skb).
+Then get_initial_state will goto out and the freed skb will be used by
+return value skb->len, which is a uaf bug.
+
+What's worse, the same problem goes even further: skb can also be
+freed in the notify_*_state_change -> notify_*_state calls below.
+Thus 4 additional uaf bugs happened.
+
+My patch lets the problem callee functions: notify_initial_state_done
+and notify_*_state_change return an error code if errors happen.
+So that the error codes could be propagated and the uaf bugs can be avoid.
+
+v2 reports a compilation warning. This v3 fixed this warning and built
+successfully in my local environment with no additional warnings.
+v2: https://lore.kernel.org/patchwork/patch/1435218/

+Fixes: a29728463b254 ("drbd: Backport the "events2" command")

+Subject: net: stmmac: Fix unset max_speed difference between DT and non-DT
+ platforms
+
+From: Chen-Yu Tsai <wens@csie.org>
+
+[ Upstream commit c21cabb0fd0b54b8b54235fc1ecfe1195a23bcb2 ]
+
+In commit 9cbadf094d9d ("net: stmmac: support max-speed device tree
+property"), when DT platforms don't set "max-speed", max_speed is set to
+-1; for non-DT platforms, it stays the default 0.
+
+Prior to commit eeef2f6b9f6e ("net: stmmac: Start adding phylink support"),
+the check for a valid max_speed setting was to check if it was greater
+than zero. This commit got it right, but subsequent patches just checked
+for non-zero, which is incorrect for DT platforms.
+
+In commit 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()")
+the conversion switched completely to checking for non-zero value as a
+valid value, which caused 1000base-T to stop getting advertised by
+default.
+
+Instead of trying to fix all the checks, simply leave max_speed alone if
+DT property parsing fails.
+
+Fixes: 9cbadf094d9d ("net: stmmac: support max-speed device tree property")
+Fixes: 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()")

+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit 16ed828b872d12ccba8f07bcc446ae89ba662f9c ]
+
+The error handling path of the probe releases a resource that is not freed
+in the remove function. In some cases, a ioremap() must be undone.
+
+Add the missing iounmap() call in the remove function.
