9 daysi2c: rcar: bring hardware to known state when probingWolfram Sang1-5/+12
[ Upstream commit 4e36c0f20cb1c74c7bd7ea31ba432c1c4a989031 ] When probing, the hardware is not brought into a known state. This may be a problem when a hypervisor restarts Linux without resetting the hardware, leaving an old state running. Make sure the hardware gets initialized, especially interrupts should be cleared and disabled.

commit 4e60131d0d36af65ab9c9144f4f163fe97ae36e8 upstream. hpet_compat_ioctl and read file operations failed to handle parameters from 32-bit userspace and thus samples/timers/hpet_example.c fails as below. root@intel-x86-64:~# ./hpet_example-32.out poll /dev/hpet 1 2 -hpet: executing poll hpet_poll: HPET_IRQFREQ failed This patch fixes cmd and arg handling in hpet_compat_ioctl and adds compat handling for 32-bit userspace in hpet_read. hpet_example now shows that it works for both 64-bit and 32-bit. root@intel-x86-64:~# ./hpet_example-32.out poll /dev/hpet 1 2 -hpet: executing poll hpet_poll: info.hi_flags 0x0 hpet_poll: expired time = 0xf4298 hpet_poll: revents = 0x1 hpet_poll: data 0x1 hpet_poll: expired time = 0xf4235 hpet_poll: revents = 0x1 hpet_poll: data 0x1 root@intel-x86-64:~# ./hpet_example-64.out poll /dev/hpet 1 2 -hpet: executing poll hpet_poll: info.hi_flags 0x0 hpet_poll: expired time = 0xf42a1 hpet_poll: revents = 0x1 hpet_poll: data 0x1 hpet_poll: expired time = 0xf4232 hpet_poll: revents = 0x1 hpet_poll: data 0x1 Cc: stable@vger.kernel.org Signed-off-by: He Zhe <zhe.he@windriver.com> Fixes: 54066a57c584 ("hpet: kill BKL, add compat_ioctl") Reviewed-by: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20240606123908.738733-1-zhe.he@windriver.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
9 daysUSB: core: Fix duplicate endpoint bug by clearing reserved bits in the ↵Alan Stern1-3/+15
descriptor commit a368ecde8a5055b627749b09c6218ef793043e47 upstream. Syzbot has identified a bug in usbcore (see the Closes: tag below) caused by our assumption that the reserved bits in an endpoint descriptor's bEndpointAddress field will always be 0. As a result of the bug, the endpoint_is_duplicate() routine in config.c (and possibly other routines as well) may believe that two descriptors are for distinct endpoints, even though they have the same direction and endpoint number. This can lead to confusion, including the bug identified by syzbot (two descriptors with matching endpoint numbers and directions, where one was interrupt and the other was bulk). To fix the bug, we will clear the reserved bits in bEndpointAddress when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1 specs say these bits are "Reserved, reset to zero".) This requires us to make a copy of the descriptor earlier in usb_parse_endpoint() and use the copy instead of the original when checking for duplicates.

9 daysusb: gadget: configfs: Prevent OOB read/write in usb_string_copy()Lee Jones1-0/+3
commit 6d3c721e686ea6c59e18289b400cc95c76e927e0 upstream. Userspace provided string 's' could trivially have the length zero. Left unchecked this will firstly result in an OOB read in the form `if (str[0 - 1] == '\n') followed closely by an OOB write in the form `str[0 - 1] = '\0'`. There is already a validating check to catch strings that are too long. Let's supply an additional check for invalid strings that are too short.

commit 2604e08ff251dba330e16b65e80074c9c540aad7 upstream. FM350-GL is 5G Sub-6 WWAN module which uses M.2 form factor interface. It is based on Mediatek's MTK T700 CPU. The module supports PCIe Gen3 x1 and USB 2.0 and 3.0 interfaces. The manufacturer states that USB is "for debug" but it has been confirmed to be fully functional, except for modem-control requests on some of the interfaces. USB device composition is controlled by AT+GTUSBMODE=<mode> command. Two values are currently supported for the <mode>: 40: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB 41: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB+AP(LOG)+AP(META) (default value) [ Note that the functions above are not ordered by interface number. ] Mode 40 corresponds to: T: Bus=03 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 22 Spd=480 MxCh= 0 D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=0e8d ProdID=7126 Rev= 0.01 S: Manufacturer=Fibocom Wireless Inc.

9 daysbnx2x: Fix multiple UBSAN array-index-out-of-boundsGhadi Elie Rahme1-1/+1
commit 134061163ee5ca4759de5c24ca3bd71608891ba7 upstream. Fix UBSAN warnings that occur when using a system with 32 physical cpu cores or more, or when the user defines a number of Ethernet queues greater than or equal to FP_SB_MAX_E1x using the num_queues module parameter. Currently there is a read/write out of bounds that occurs on the array "struct stats_query_entry query" present inside the "bnx2x_fw_stats_req" struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h". Looking at the definition of the "struct stats_query_entry query" array: struct stats_query_entry query[FP_SB_MAX_E1x+ BNX2X_FIRST_QUEUE_QUERY_IDX]; FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3 meaning the array has a total size of 19. Since accesses to "struct stats_query_entry query" are offset-ted by BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet queues should not exceed FP_SB_MAX_E1x (16). However one of these queues is reserved for FCOE and thus the number of Ethernet queues should be set to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if it is not. This is also described in a comment in the source code in drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition of FP_SB_MAX_E1x. Below is the part of this explanation that it important for this patch /* * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is * control by the number of fast-path status blocks supported by the * device (HW/FW). Each fast-path status block (FP-SB) aka non-default * status block represents an independent interrupts context that can * serve a regular L2 networking queue. However special L2 queues such * as the FCoE queue do not require a FP-SB and other components like * the CNIC may consume FP-SB reducing the number of possible L2 queues * * If the maximum number of FP-SB available is X then: * a. If CNIC is supported it consumes 1 FP-SB thus the max number of * regular L2 queues is Y=X-1 * b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor) * c. If the FCoE L2 queue is supported the actual number of L2 queues * is Y+1 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for * slow-path interrupts) or Y+2 if CNIC is supported (one additional * FP interrupt context for the CNIC). * e. The number of HW context (CID count) is always X or X+1 if FCoE * L2 queue is supported. The cid for the FCoE L2 queue is always X. */ However this driver also supports NICs that use the E2 controller which can handle more queues due to having more FP-SB represented by FP_SB_MAX_E2. Looking at the commits when the E2 support was added, it was originally using the E1x parameters: commit f2e0899f0f27 ("bnx2x: Add 57712 support"). Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver was later updated to take full advantage of the E2 instead of having it be limited to the capabilities of the E1x. But as far as we can tell, the array "stats_query_entry query" was still limited to using the FP-SB available to the E1x cards as part of an oversignt when the driver was updated to take full advantage of the E2, and now with the driver being aware of the greater queue size supported by E2 NICs, it causes the UBSAN warnings seen in the stack traces below. This patch increases the size of the "stats_query_entry query" array by replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle both types of NICs.

This appears to be intended to guard against the list chip->mdios being empty. However, it is not the correct check as the implementation of list_first_entry is not designed to return NULL for empty lists. Instead, use list_first_entry_or_null() which does return NULL if the list is empty. Flagged by Smatch. Compile tested only.

[ Upstream commit a08b8f8557ad88ffdff8905e5da972afe52e3307 ] This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "ff" variable is a pointer to "struct ff_device" and this structure ends in a flexible array: struct ff_device { [...] struct file *effect_owners[] __counted_by(max_effects); }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count * size" in the kzalloc() function. The struct_size() helper returns SIZE_MAX on overflow. So, refactor the comparison to take advantage of this. This way, the code is more readable and safer. This code was detected with the help of Coccinelle, and audited and modified manually.

[ Upstream commit 0e148a522b8453115038193e19ec7bea71403e4a ] The code ignored the I2C_M_RD flag on I2C messages. Instead it assumed an i2c transaction with a single message must be a write operation and a transaction with two messages would be a read operation. Though this works for the driver code, it leads to problems once the i2c device is exposed to code not knowing this convention. For example, I did "insmod i2c-dev" and issued read requests from userspace, which were translated into write requests and destroyed the EEPROM of my device. So, just check and respect the I2C_M_READ flag, which indicates a read when set on a message. If it is absent, it is a write message. Incidentally, changing from the case statement to a while loop allows the code to lift the limitation to two i2c messages per transaction. There are 4 more *_i2c_transfer functions affected by the same behaviour and limitation that should be fixed in the same way.

[ Upstream commit ca0b44e20a6f3032224599f02e7c8fb49525c894 ] The existing behavior of ib_umad, which maintains received MAD packets in an unbounded list, poses a risk of uncontrolled growth. As user-space applications extract packets from this list, the rate of extraction may not match the rate of incoming packets, leading to potential list overflow. To address this, we introduce a limit to the size of the list. After considering typical scenarios, such as OpenSM processing, which can handle approximately 100k packets per second, and the 1-second retry timeout for most packets, we set the list size limit to 200k. Packets received beyond this limit are dropped, assuming they are likely timed out by the time they are handled by user-space. Notably, packets queued on the receive list due to reasons like timed-out sends are preserved even when the list is full.

commit 058722ee350c0bdd664e467156feb2bf5d9cc271 upstream. Avoid spurious link status logs that may ultimately be wrong; for example, if the link is set to down with the cable plugged, then the cable is unplugged and after this the link is set to up, the last new log that is appearing is incorrectly telling that the link is up. In order to avoid errors, show link status logs after link_reset processing, and in order to avoid spurious as much as possible, only show the link loss when some link status change is detected. cc: stable@vger.kernel.org Fixes: e2ca90c276e1 ("ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver") Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.

2024-07-05iio: chemical: bme680: Fix sensor data read operationVasileios Amoiridis2-0/+48
commit 4241665e6ea063a9c1d734de790121a71db763fc upstream. A read operation is happening as follows: a) Set sensor to forced mode b) Sensor measures values and update data registers and sleeps again c) Read data registers In the current implementation the read operation happens immediately after the sensor is set to forced mode so the sensor does not have the time to update properly the registers. This leads to the following 2 problems: 1) The first ever value which is read by the register is always wrong 2) Every read operation, puts the register into forced mode and reads the data that were calculated in the previous conversion. This behaviour was tested in 2 ways: 1) The internal meas_status_0 register was read before and after every read operation in order to verify that the data were ready even before the register was set to forced mode and also to check that after the forced mode was set the new data were not yet ready. 2) Physically changing the temperature and measuring the temperature This commit adds the waiting time in between the set of the forced mode and the read of the data. The function is taken from the Bosch BME68x Sensor API [1].

2024-07-05iio: chemical: bme680: Fix overflows in compensate() functionsVasileios Amoiridis1-6/+6
commit fdd478c3ae98c3f13628e110dce9b6cfb0d9b3c8 upstream. There are cases in the compensate functions of the driver that there could be overflows of variables due to bit shifting ops. These implications were initially discussed here [1] and they were mentioned in log message of Commit 1b3bd8592780 ("iio: chemical: Add support for Bosch BME680 sensor").

commit ebc4fc34eae8ddfbef49f2bdaced1bf4167ef80d upstream. jmicron_pmos() and sdhci_pci_probe() use pci_{read,write}_config_byte() that return PCIBIOS_* codes. The return code is then returned as is by jmicron_probe() and sdhci_pci_probe(). Similarly, the return code is also returned as is from jmicron_resume(). Both probe and resume functions should return normal errnos. Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning them the fix these issues.
