It is not allowed to call kfree_skb() from hardware interrupt context or with interrupts being disabled. So replace kfree_skb() with dev_kfree_skb_irq() under spin_lock_irqsave(). Compile tested only. Fixes: fc75122f ("libertas_tf: use irqsave() in USB's complete callback") Signed-off-by:

After the DMA buffer is mapped to a physical address, address is stored in pktids in brcmf_msgbuf_alloc_pktid(). Then, pktids is parsed in brcmf_msgbuf_get_pktid()/brcmf_msgbuf_release_array() to obtain physaddr and later unmap the DMA buffer. But when count is always equal to pktids->array_size, physaddr isn't stored in pktids and the DMA buffer will not be unmapped anyway. Fixes: 9a1bb602 ("brcmfmac: Adding msgbuf protocol.")

This patch fixes a stack-out-of-bounds read in brcmfmac that occurs when 'buf' that is not null-terminated is passed as an argument of strsep() in brcmf_c_preinit_dcmds(). This buffer is filled with a firmware version string by memcpy() in brcmf_fil_iovar_data_get(). The patch ensures buf is null-terminated. Found by a modified version of syzkaller.

It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead. The difference between them is free reason, dev_kfree_skb_irq() means the SKB is dropped in error and dev_consume_skb_irq() means the SKB is consumed in normal. In this case, dev_kfree_skb() is called to free and drop the SKB when it's reset, so replace it with dev_kfree_skb_irq(). Compile tested only. Fixes: 43f66a6c ("Add ipw2200 wireless driver.")

This chip is found in cheap USB devices from TP-Link, D-Link, etc. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. Chip versions older than "I cut" need software rate control. That will be in the next commit. Until then MCS7 is used for all data frames. The "I cut" chips are not supported. They require different firmware and initialisation tables. Support can be added if someone has the hardware to test it. Co-developed-by:

Originally, each chip maintains its own format version followed firmware it uses. As new chip is added, firmware changes format of exchange messages to have rich information to handle more conditions. When old chip is going to upgrade firmware, it could use new format and driver needs to maintain compatibility with old firmware. So, add this version array to achieve this goal. Signed-off-by:

There is a global-out-of-bounds reported by KASAN: BUG: KASAN: global-out-of-bounds in _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae] Read of size 1 at addr ffffffffa0773c43 by task NetworkManager/411 CPU: 6 PID: 411 Comm: NetworkManager Tainted: G D 6.1.0-rc8+ #144 e15588508517267d37 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), Call Trace: <TASK> ... kasan_report+0xbb/0x1c0 _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae] rtl8821ae_phy_bb_config.cold+0x346/0x641 [rtl8821ae] rtl8821ae_hw_init+0x1f5e/0x79b0 [rtl8821ae] ... </TASK> The root cause of the problem is that the comparison order of "prate_section" in _rtl8812ae_phy_set_txpower_limit() is wrong. The _rtl8812ae_eq_n_byte() is used to compare the first n bytes of the two strings from tail to head, which causes the problem. In the _rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet this requirement by carefully designing the comparison order. For example, "pregulation" and "pbandwidth" are compared in order of length from small to large, first is 3 and last is 4. However, the comparison order of "prate_section" dose not obey such order requirement, therefore when "prate_section" is "HT", when comparing from tail to head, it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As mentioned above, the _rtl8812ae_eq_n_byte() has the same function as strcmp(), so just strcmp() is enough. Fix it by removing _rtl8812ae_eq_n_byte() and use strcmp() barely. Although it can be fixed by adjusting the comparison order of "prate_section", this may cause the value of "rate_section" to not be from 0 to 5. In addition, commit "21e4b072" not only moved driver from staging to regular tree, but also added setting txpower limit function during the driver config phase, so the problem was introduced by this commit.

Normally, system image should ensure firmware integrity, but we provide an advance feature to ensure this by security section along with firmware. To enable this feature, custom ID is programmed into efuse, and driver will download proper security section to firmware. Since I don't have this kind hardware modules on hand yet, but new format is used by newer firmware. Therefore, I prepare this patch in advance to consider size of security section as a factor of checking rule of firmware size, but don't actually download security section to firmware. This patch is backward compatible, so it will be safe to have this change before adding an new format firmware to linux-firmware repository. Signed-off-by:

ER (Extended Range) SU is to have a larger coverage. We set this as a RA capability, and then firmware can choose ER SU to transmit packets to reception at cell edge. For 8852C, it needs to fill this capability in TXWD, so update rtw89_build_txwd_info0_v1(). Signed-off-by:

It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead. The difference between them is free reason, dev_kfree_skb_irq() means the SKB is dropped in error and dev_consume_skb_irq() means the SKB is consumed in normal. In this case, dev_kfree_skb() is called to free and drop the SKB when it's shutdown, so replace it with dev_kfree_skb_irq(). Compile tested only.

Just because priv->cck_agc_report_type is only one bit doesn't mean it works like a bool. The value assigned to it loses all bits except bit 0, so only assign 0 or 1 to it. This affects the RTL8192EU, but rtl8xxxu already can't connect to any networks with this chip, so it probably didn't bother anyone.

It is not allowed to call kfree_skb() from hardware interrupt context or with interrupts being disabled. All the SKBs have been dequeued from the old queue, so it's safe to enqueue these SKBs to a free queue, then free them after spin_unlock_irqrestore() at once. Compile tested only.
