If, for any reason, we're going to attempt to flush the queues while quiet CSA is happening, this cannot succeed. This could be the case if for example mac80211 were to flush after TXing e.g. a deauth frame due to disconnecting during the CSA. In this case, drop the frames instead, the firmware won't let us do any transmissions and may also become unhappy if we're not going to disconnect quickly enough. Currently this doesn't happen as mac80211 stops queues, but we'll want to let mac80211 know not to stop queues for proper multi-link support during CSA, so we need to handle this case. Signed-off-by:

Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct qtnf_bus by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at qtnf_pcie_probe(). The free of the device occurs at qtnf_pcie_remove(). [1] https://lore.kernel.org/all/20240229225910.79e224cf@kernel.org/Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

The kzalloc() in brcmf_pcie_download_fw_nvram() will return null if the physical memory has run out. As a result, if we use get_random_bytes() to generate random bytes in the randbuf, the null pointer dereference bug will happen. In order to prevent allocation failure, this patch adds a separate function using buffer on kernel stack to generate random bytes in the randbuf, which could prevent the kernel stack from overflow. Fixes: 91918ce8 ("wifi: brcmfmac: pcie: Provide a buffer of random bytes to the device") Suggested-by:

The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attempting to use it.

We used EHT capability of 20MHz-only as rate mask to RA (rate adaptive) H2C command when connecting with AP set EHT 20MHz. It would get the wrong rate mask and the MCS rate can only reach MCS11. According to the description of 802.11be spec, if all supported channel bandwidth field of HE PHY capabilities are zero, then the EHT capability of 20MHz-only is valid. As a result, we adjust the code to set correct rate mask based on HE PHY bandwidth capability. Signed-off-by:

Herve Codina says: ==================== Add support for QMC HDLC This series introduces the QMC HDLC support. Patches were previously sent as part of a full feature series and were previously reviewed in that context: "Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1] In order to ease the merge, the full feature series has been split and needed parts were merged in v6.8-rc1: - "Prepare the PowerQUICC QMC and TSA for the HDLC QMC driver" [2] - "Add support for framer infrastructure and PEF2256 framer" [3] This series contains patches related to the QMC HDLC part (QMC HDLC driver): - Introduce the QMC HDLC driver (patches 1 and 2) - Add timeslots change support in QMC HDLC (patch 3) - Add framer support as a framer consumer in QMC HDLC (patch 4) Compare to the original full feature series, a modification was done on patch 3 in order to use a coherent prefix in the commit title. I kept the patches unsquashed as they were previously sent and reviewed. Of course, I can squash them if needed. Compared to the previous iteration: https://lore.kernel.org/linux-kernel/20240306080726.167338-1-herve.codina@bootlin.com/ this v7 series mainly: - Rename a variable. - Fix reverse xmas tree declarations. - Add 'Acked-by' tag. ==================== Signed-off-by:
