Commit 9e4555d1e54a ("gpiolib: add support for scope-based management to gpio_device") sought to add scope-based gpio_device refcounting, but erroneously forgot a negation of IS_ERR_OR_NULL(). As a result, gpio_device_put() is not called if the gpio_device pointer is valid (meaning the ref is leaked), but only called if the pointer is NULL or an ERR_PTR().

2024-01-14net: ravb: Fix dma_addr_t truncation in error caseNikita Yushchenko1-1/+1
In ravb_start_xmit(), ravb driver uses u32 variable to store result of dma_map_single() call. Since ravb hardware has 32-bit address fields in descriptors, this works properly when mapping is successful - it is platform's job to provide mapping addresses that fit into hardware limitations. However, in failure case dma_map_single() returns DMA_MAPPING_ERROR constant that is 64-bit when dma_addr_t is 64-bit. Storing this constant in u32 leads to truncation, and further call to dma_mapping_error() fails to notice the error. Fix that by storing result of dma_map_single() in a dma_addr_t variable.

nuvoton,npcm750-pwm-fan Commit 89fec128d5d1 ("hwmon: (npcm750-pwm-fan) Add NPCM8xx support") introduced support for PWM fans on Nuvoton's npcm845 SoC. This chip supports three PWM modules with four PWM channels each. The older npcm750 only supported two PWM modules. The commit did not take into account that the older SoC only supported two PWM modules. This results in a crash if npcm750 is instantiated when the code attempts to instantiate the non-existing third PWM module.

John Fastabend says: ==================== tls fixes for SPLICE with more hint Syzbot found a splat where it tried to splice data over a tls socket with the more hint and sending greater than the number of frags that fit in a msg scatterlist. This resulted in an error where we do not correctly send the data when the msg sg is full. The more flag being just a hint not a strict contract. This then results in the syzbot warning on the next send. Edward generated an initial patch for this which checked for a full msg on entry to the sendmsg hook. This fixed the WARNING, but didn't fully resolve the issue because the full msg_pl scatterlist was never sent resulting in a stuck socket. In this series instead avoid the situation by forcing the send on the splice that fills the scatterlist. Also in original thread I mentioned it didn't seem to be enough to simply fix the send on full sg problem. That was incorrect and was really a bug in my test program that was hanging the test program. I had setup a repair socket and wasn't handling it correctly so my tester got stuck. Thanks. Please review. Fix in patch 1 and test in patch 2. v2: use SPLICE_F_ flag names instead of cryptic 0xe ==================== Signed-off-by: David S. Miller <[email protected]>
2024-01-14net: tls, add test to capture error on large spliceJohn Fastabend1-0/+14
syzbot found an error with how splice() is handled with a msg greater than 32. This was fixed in previous patch, but lets add a test for it to ensure it continues to work.

2024-01-14net: tls, fix WARNIING in __sk_msg_freeJohn Fastabend1-1/+5
A splice with MSG_SPLICE_PAGES will cause tls code to use the tls_sw_sendmsg_splice path in the TLS sendmsg code to move the user provided pages from the msg into the msg_pl. This will loop over the msg until msg_pl is full, checked by sk_msg_full(msg_pl). The user can also set the MORE flag to hint stack to delay sending until receiving more pages and ideally a full buffer. If the user adds more pages to the msg than can fit in the msg_pl scatterlist (MAX_MSG_FRAGS) we should ignore the MORE flag and send the buffer anyways. What actually happens though is we abort the msg to msg_pl scatterlist setup and then because we forget to set 'full record' indicating we can no longer consume data without a send we fallthrough to the 'continue' path which will check if msg_data_left(msg) has more bytes to send and then attempts to fit them in the already full msg_pl. Then next iteration of sender doing send will encounter a full msg_pl and throw the warning in the syzbot report. To fix simply check if we have a full_record in splice code path and if not send the msg regardless of MORE flag.
