[ Upstream commit e4e5a865 ] The emulated ptimer needs to track the level changes, otherwise the the interrupt will never get deasserted, resulting in the guest getting stuck in an interrupt storm if it enables ptimer interrupts. This was found with kvm-unit-tests; the ptimer tests hung as soon as interrupts were enabled. Typical Linux guests don't have a problem as they prefer using the virtual timer.

[ Upstream commit cf18cecc ] Some transceivers may comply with SFF-8472 even though they do not implement the Digital Diagnostic Monitoring (DDM) interface described in the spec. The existence of such area is specified by the 6th bit of byte 92, set to 1 if implemented. Currently, without checking this bit, bnx2x fails trying to read sfp module's EEPROM with the follow message: ethtool -m enP5p1s0f1 Cannot get Module EEPROM data: Input/output error Because it fails to read the additional 256 bytes in which it is assumed to exist the DDM data. This issue was noticed using a Mellanox Passive DAC PN 01FT738. The EEPROM data was confirmed by Mellanox as correct and similar to other Passive DACs from other manufacturers. Signed-off-by:

[ Upstream commit 9642fa73 ] Stopping external metadata arrays during resync/recovery causes retries, loop of interrupting and starting reconstruction, until it hit at good moment to stop completely. While these retries curr_mark_cnt can be small- especially on HDD drives, so subtraction result can be smaller than 0. However it is casted to uint without checking. As a result of it the status bar in /proc/mdstat while stopping is strange (it jumps between 0% and 99%). The real problem occurs here after commit 72deb455 ("block: remove CONFIG_LBDAF"). Sector_div() macro has been changed, now the divisor is casted to uint32. For db = -8 the divisior(db/32-1) becomes 0. Check if db value can be really counted and replace these macro by div64_u64() inline. Signed-off-by:

[ Upstream commit 942a8993 ] The call to sc_buffer_alloc currently returns NULL (no buffer) or a buffer descriptor. There is a third case when the port is down. Currently that returns NULL and this prevents the caller from properly handling the sc_buffer_alloc() failure. A verbs code link test after the call is racy so the indication needs to come from the state check inside the allocation routine to be valid. Fix by encoding the ECOMM failure like SDMA. IS_ERR_OR_NULL() tests are added at all call sites. For verbs send, this needs to treat any error by returning a completion without any MMIO copy.

It makes sense to me because we want the status of a fully setup HS400, so it will increase the reliability of the mmc_switch_status() command. Reported-by:

Toshiaki Makita authored
[ Upstream commit d4dd153d ] dev_map_free() waits for flush_needed bitmap to be empty in order to ensure all flush operations have completed before freeing its entries. However the corresponding clear_bit() was called before using the entries, so the entries could be used after free. All access to the entries needs to be done before clearing the bit. It seems commit a5e2da6e ("bpf: netdev is never null in __dev_map_flush") accidentally changed the clear_bit() and memory access order. Note that the problem happens only in __dev_map_flush(), not in dev_map_flush_old(). dev_map_flush_old() is called only after nulling out the corresponding netdev_map entry, so dev_map_free() never frees the entry thus no such race happens there.

[ Upstream commit 56357234 ] In multiple SSID cases, it takes time to prepare every AP interface to be ready in initializing phase. If a sta already knows everything it needs to join one of the APs and sends authentication to the AP which is not fully prepared at this point of time, AP's channel context could be NULL. As a result, warning message occurs. Even worse, if the AP is under attack via tools such as MDK3 and massive authentication requests are received in a very short time, console will be hung due to kernel warning messages. WARN_ON_ONCE() could be a better way for indicating warning messages without duplicate messages to flood the console.

[ Upstream commit 4729ec8c ] kvm_device->destroy() seems to be supposed to free its kvm_device struct, but vgic_its_destroy() is not currently doing this, resulting in a memory leak, resulting in kmemleak reports such as the following: unreferenced object 0xffff800aeddfe280 (size 128): comm "qemu-system-aar", pid 13799, jiffies 4299827317 (age 1569.844s) [...] backtrace: [<00000000a08b80e2>] kmem_cache_alloc+0x178/0x208 [<00000000dcad2bd3>] kvm_vm_ioctl+0x350/0xbc0 Fix it.

[ Upstream commit ce9a53eb ] There are several scenarios that keyboard can NOT wake up system from suspend, e.g., if a keyboard is depressed between system device suspend phase and device noirq suspend phase, the keyboard ISR will be called and both keyboard depress and release interrupts will be disabled, then keyboard will no longer be able to wake up system. Another scenario would be, if a keyboard is kept depressed, and then system goes into suspend, the expected behavior would be when keyboard is released, system will be waked up, but current implementation can NOT achieve that, because both depress and release interrupts are disabled in ISR, and the event check is still in progress. To fix these issues, need to make sure keyboard's depress or release interrupt is enabled after noirq device suspend phase, this patch moves the suspend/resume callback to noirq suspend/resume phase, and enable the corresponding interrupt according to current keyboard status.

[ Upstream commit d0e1f211 ] In RV32, udelay would delay the wrong cycle. When it shifts right "UDELAY_SHIFT" bits, it either delays 0 cycle or 1 cycle. It only works correctly in RV64. Because the 'ucycles' always needs to be 64 bits variable. Signed-off-by:
