These commits share the global HVS state, so we have some code to make sure we run commits in sequence. This synchronization code is one of the first thing that runs in vc4_atomic_commit_tail(). Another constraints we have is that we need to make sure the HVS clock gets a boost during the commit. That code relies on clk_set_min_rate and will remove the old minimum and set a new one. We also need another, temporary, minimum for the duration of the commit. The algorithm is thus to set a temporary minimum, drop the previous one, do the commit, and finally set the minimum for the current mode. However, the part that sets the temporary minimum and drops the older one runs before the commit synchronization code. Thus, under the proper conditions, we can end up mixing up the minimums and ending up with the wrong one for our current step. To avoid it, let's move the clock setup in the protected section.

FAILED: patch "[PATCH] net: stmmac: Avoid DMA_CHAN_CONTROL write if no Split Header" failed to apply to 5.10-stable tree

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From f8e7dfd6fdabb831846ab1970a875746559d491b Mon Sep 17 00:00:00 2001 From: Vincent Whitchurch <vincent.whitchurch(a)axis.com> Date: Fri, 26 Nov 2021 16:51:15 +0100 Subject: [PATCH] net: stmmac: Avoid DMA_CHAN_CONTROL write if no Split Header support The driver assumes that split headers can be enabled/disabled without stopping/starting the device, so it writes DMA_CHAN_CONTROL from stmmac_set_features(). However, on my system (IP v5.10a without Split Header support), simply writing DMA_CHAN_CONTROL when DMA is running (for example, with the commands below) leads to a TX watchdog timeout. host$ socat TCP-LISTEN:1024,fork,reuseaddr - & device$ ethtool -K eth0 tso off device$ ethtool -K eth0 tso on device$ dd if=/dev/zero bs=1M count=10 | socat - TCP4:host:1024 <tx watchdog timeout> Note that since my IP is configured without Split Header support, the driver always just reads and writes the same value to the DMA_CHAN_CONTROL register. I don't have access to any platforms with Split Header support so I don't know if these writes to the DMA_CHAN_CONTROL while DMA is running actually work properly on such systems. I could not find anything in the databook that says that DMA_CHAN_CONTROL should not be written when the DMA is running. But on systems without Split Header support, there is in any case no need to call enable_sph() in stmmac_set_features() at all since SPH can never be toggled, so we can avoid the watchdog timeout there by skipping this call.

FAILED: patch "[PATCH] net/mlx4_en: Fix an use-after-free bug in" failed to apply to 4.9-stable tree

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From addad7643142f500080417dd7272f49b7a185570 Mon Sep 17 00:00:00 2001 From: Zhou Qingyang <zhou1615(a)umn.edu> Date: Wed, 1 Dec 2021 00:44:38 +0800 Subject: [PATCH] net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources() In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv(). After that mlx4_en_alloc_resources() is called and there is a dereference of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to a use after free problem on failure of mlx4_en_copy_priv(). Fix this bug by adding a check of mlx4_en_copy_priv() This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_MLX4_EN=m show no new warnings, and our static analyzer no longer warns about this code.
