With char becoming unsigned by default, and with `char` alone being ambiguous and based on architecture, we get a warning when assigning the unchecked output of hex_to_bin() to that unsigned char. Mark `key` as a `u8`, which matches the struct's type, and then check each call to hex_to_bin() before casting. Cc: Kalle Valo <kvalo@kernel.org> Cc: linux-wireless@vger.kernel.org Signed-off-by:

Fixes a warning that occurs when rc table support is enabled (IEEE80211_HW_SUPPORTS_RC_TABLE) in mac80211_hwsim and the PS mode is changed via the exported debugfs attribute. When the PS mode is changed, a packet is broadcasted via hwsim_send_nullfunc by creating and transmitting a plain skb with only header initialized. The ieee80211 rate array in the control buffer is zero-initialized. When ratetbl support is enabled, ieee80211_get_tx_rates is called for the skb with sta parameter set to NULL and thus no ratetbl can be used. The final rate array then looks like [-1,0; 0,0; 0,0; 0,0] which causes the warning in ieee80211_get_tx_rate. The issue is fixed by setting the count of the first rate with idx '0' to 1 and hence ieee80211_get_tx_rates won't overwrite it with idx '-1'. Signed-off-by:

When invoking function cfg80211_calculate_bitrate_eht about (320 MHz, EHT-MCS 13, EHT-NSS 2, EHT-GI 0), which means the parameters as flags: 0x80, bw: 7, mcs: 13, eht_gi: 0, nss: 2, this formula (result * rate->nss) will overflow and causes the returned bitrate to be 3959 when it should be 57646. Here is the explanation: u64 tmp; u32 result; … /* tmp = result = 4 * rates_996[0] * = 4 * 480388888 = 0x72889c60 */ tmp = result; /* tmp = 0x72889c60 * 6144 = 0xabccea90000 */ tmp *= SCALE; /* tmp = 0xabccea90000 / mcs_divisors[13] * = 0xabccea90000 / 5120 = 0x8970bba6 */ do_div(tmp, mcs_divisors[rate->mcs]); /* result = 0x8970bba6 */ result = tmp; /* normally (result * rate->nss) = 0x8970bba6 * 2 = 0x112e1774c, * but since result is u32, (result * rate->nss) = 0x12e1774c, * overflow happens and it loses the highest bit. * Then result = 0x12e1774c / 8 = 39595753, */ result = (result * rate->nss) / 8; Signed-off-by:

In the function query_regdb_file() the alpha2 parameter is duplicated using kmemdup() and subsequently freed in regdb_fw_cb(). However, request_firmware_nowait() can fail without calling regdb_fw_cb() and thus leak memory. Fixes: 007f6c5e ("cfg80211: support loading regulatory database as firmware file") Signed-off-by:

On some platforms, `char` is unsigned, but this driver, for the most part, assumed it was signed. In other places, it uses `char` to mean an unsigned number, but only in cases when the values are small. And in still other places, `char` is used as a boolean. Put an end to this confusion by declaring explicit types, depending on the context.

If the cable is disconnected the PHY seems to toggle between MDI and MDI-X modes. With the MDI crossover status interrupt active this causes roughly 10 interrupts per second. As the crossover status isn't checked by the driver, the interrupt can be disabled to reduce the interrupt load. Fixes: 87461f7a ("net: phy: DP83822 initial driver submission") Signed-off-by:

Currently qdisc ingress handling (sch_handle_ingress()) doesn't set a return value and it is left to the old return value of the caller (__netif_receive_skb_core()) which is RX drop, so if the packet is consumed, caller will stop and return this value as if the packet was dropped. This causes a problem in the kernel tcp stack when having a egress tc rule forwarding to a ingress tc rule. The tcp stack sending packets on the device having the egress rule will see the packets as not successfully transmitted (although they actually were), will not advance it's internal state of sent data, and packets returning on such tcp stream will be dropped by the tcp stack with reason ack-of-unsent-data. See reproduction in [0] below. Fix that by setting the return value to RX success if the packet was handled successfully.

Currently netfilter's rpfilter and fib modules implicitely initialise ->flowic_uid with 0. This is normally the root UID. However, this isn't the case in user namespaces, where user ID 0 is mapped to a different kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get the root UID of the user namespace, thus keeping the same behaviour whether or not we're running in a user namepspace. Note, this is similar to commit 8bcfd092 ("ipv4: add missing initialization for flowi4_uid"), which fixed the rp_filter sysctl.

It's possible that the driver will dereference a qcq that doesn't exist when calling ionic_reconfigure_queues(), which causes a page fault BUG. If a reduction in the number of queues is followed by a different reconfig such as changing the ring size, the driver can hit a NULL pointer when trying to clean up non-existent queues. Fix this by checking to make sure both the qcqs array and qcq entry exists bofore trying to use and free the entry. Fixes: 101b40a0 ("ionic: change queue count with no reset") Signed-off-by:

WQ_HIGHPRI increases throughput and decreases disk latency when using dm-verity. This is important in Android for camera startup speed. The following tests were run by doing 60 seconds of random reads using a dm-verity device backed by two ramdisks. Without WQ_HIGHPRI lat (usec): min=13, max=3947, avg=69.53, stdev=50.55 READ: bw=51.1MiB/s (53.6MB/s), 51.1MiB/s-51.1MiB/s (53.6MB/s-53.6MB/s) With WQ_HIGHPRI: lat (usec): min=13, max=7854, avg=31.15, stdev=30.42 READ: bw=116MiB/s (121MB/s), 116MiB/s-116MiB/s (121MB/s-121MB/s) Further testing was done by measuring how long it takes to open a camera on an Android device. Without WQ_HIGHPRI Total verity work queue wait times (ms): 880.960, 789.517, 898.852 With WQ_HIGHPRI: Total verity work queue wait times (ms): 528.824, 439.191, 433.300 The average time to open the camera is reduced by 350ms (or 40-50%).
