[PATCH 1/4] net: fix uninitialised access in mii_nway_restart()

by Qasim Ijaz

In mii_nway_restart() during the line: bmcr = mii->mdio_read(mii->dev, mii->phy_id, MII_BMCR); The code attempts to call mii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read() utilises a local buffer, which is initialised with control_read(): unsigned char buff[2]; However buff is conditionally initialised inside control_read(): if (err == size) { memcpy(data, buf, size); } If the condition of "err == size" is not met, then buff remains uninitialised. Once this happens the uninitialised buff is accessed and returned during ch9200_mdio_read(): return (buff[0] | buff[1] << 8); The problem stems from the fact that ch9200_mdio_read() ignores the return value of control_read(), leading to uinit-access of buff. To fix this we should check the return value of control_read() and return early on error.

[Patch v2 2/3] mm/memblock: repeat setting reserved region nid if array is doubled

by Wei Yang

Commit 61167ad5fecd ("mm: pass nid to reserve_bootmem_region()") introduce a way to set nid to all reserved region. But there is a corner case it will leave some region with invalid nid. When memblock_set_node() doubles the array of memblock.reserved, it may lead to a new reserved region before current position. The new region will be left with an invalid node id. Repeat the process when detecting it.

My 5.4.291 kernel was built successfully. Best regards, Otto Barea

[PATCH v2] usb: cdns3: Fix deadlock when using NCM gadget

by Ralph Siemsen

The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit 58f2fcb3a845 ("usb: cdnsp: Fix deadlock issue during using NCM gadget"). Under PREEMPT_RT the deadlock can be readily triggered by heavy network traffic, for example using "iperf --bidir" over NCM ethernet link. The deadlock occurs because the threaded interrupt handler gets preempted by a softirq, but both are protected by the same spinlock. Prevent deadlock by disabling softirq during threaded irq handler. cc: stable(a)vger.kernel.org Fixes: 7733f6c32e36 ("usb: cdns3: Add Cadence USB3 DRD Driver") Signed-off-by: Ralph Siemsen <ralph.siemsen(a)linaro.org> --- v2 changes: - move the fix up the call stack, as per discussion at https://lore.kernel.org/linux-rt-devel/20250226082931.-XRIDa6D@linutronix.d… --- drivers/usb/cdns3/cdns3-gadget.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/usb/cdns3/cdns3-gadget.c b/drivers/usb/cdns3/cdns3-gadget.c index fd1beb10bba72..19101ff1cf1bd 100644 --- a/drivers/usb/cdns3/cdns3-gadget.c +++ b/drivers/usb/cdns3/cdns3-gadget.c @@ -1963,6 +1963,7 @@ static irqreturn_t cdns3_device_thread_irq_handler(int irq, void *data) unsigned int bit; unsigned long reg; + local_bh_disable(); spin_lock_irqsave(&priv_dev->lock, flags); reg = readl(&priv_dev->regs->usb_ists); @@ -2004,6 +2005,7 @@ static irqreturn_t cdns3_device_thread_irq_handler(int irq, void *data) irqend: writel(~0, &priv_dev->regs->ep_ien); spin_unlock_irqrestore(&priv_dev->lock, flags); + local_bh_enable(); return ret; } --- base-commit: 4701f33a10702d5fc577c32434eb62adde0a1ae1 change-id: 20250312-rfs-cdns3-deadlock-697df5cad3ce Best regards, -- Ralph Siemsen <ralph.siemsen(a)linaro.org>
