2023-12-22MAINTAINERS: drop Eric Paris from his SELinux rolePaul Moore
Eric Paris is an important part of SELinux history and we are all thankful not only for his stint as maintainer, but his numerous contributions over the years. Unfortunately for us, Eric has moved on to other things and hasn't contributed to the SELinux community in several years (his last SELinux kernel commit was in 2013) so it's time to officially drop Eric as a maintainer. I also want to get ahead of any claims of impropriety and state that this change has absolutely nothing to do with commit 2be4d74f2fd4 ;) Thanks for all you've done Eric, you'll always be welcome back.

bhash2 added a new member sk_bind2_node in struct sock to link sockets to bhash2 in addition to bhash. bhash is still needed to search conflicting sockets efficiently from a port for the wildcard address. However, bhash itself need not have sockets. If we link each bhash2 bucket to the corresponding bhash bucket, we can iterate the same set of the sockets from bhash2 via bhash. This patch links bhash2 to bhash only, and the actual use will be in the later patches. Finally, we will remove sk_bind2_node.

In bhash2, IPv4/IPv6 addresses are saved in two union members, which complicate address checks in inet_bind2_bucket_addr_match() and inet_bind2_bucket_match_addr_any() considering uninitialised memory and v4-mapped-v6 conflicts. Let's simplify that by saving IPv4 address as v4-mapped-v6 address and defining tb2.rcv_saddr as tb2.v6_rcv_saddr.s6_addr32[3]. Then, we can compare v6 address as is, and after checking v4-mapped-v6, we can compare v4 address easily. Also, we can remove tb2->family.

After the commit 666cf30a589a ("HID: sensor-hub: Allow multi-function sensor devices") hub devices are claimed by hidraw driver in hid_connect(). This causes stoppping of processing HID reports by hid core due to optimization. In such case, the hid-sensor-custom driver cannot match a known custom sensor in hid_sensor_custom_get_known() because it try to check custom properties which weren't filled from the report because hid core didn't parsed it. As result, custom sensors like hinge angle sensor and LISS sensors don't work. Mark the sensor hub devices claimed by some driver to avoid hidraw-related optimizations.

2023-12-22Bluetooth: Fix atomicity violation in {min,max}_key_size_setGui-Dong Han
In min_key_size_set(): if (val > hdev->le_max_key_size || val < SMP_MIN_ENC_KEY_SIZE) return -EINVAL; hci_dev_lock(hdev); hdev->le_min_key_size = val; hci_dev_unlock(hdev); In max_key_size_set(): if (val > SMP_MAX_ENC_KEY_SIZE || val < hdev->le_min_key_size) return -EINVAL; hci_dev_lock(hdev); hdev->le_max_key_size = val; hci_dev_unlock(hdev); The atomicity violation occurs due to concurrent execution of set_min and set_max funcs.Consider a scenario where setmin writes a new, valid 'min' value, and concurrently, setmax writes a value that is greater than the old 'min' but smaller than the new 'min'. In this case, setmax might check against the old 'min' value (before acquiring the lock) but write its value after the 'min' has been updated by setmin. This leads to a situation where the 'max' value ends up being smaller than the 'min' value, which is an inconsistency. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To resolve this issue, it is suggested to encompass the validity checks within the locked sections in both set_min and set_max funcs. The modification ensures that the validation of 'val' against the current min/max values is atomic, thus maintaining the integrity of the settings. With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.

2023-12-22Bluetooth: L2CAP: Fix possible multiple reject sendFrédéric Danis
In case of an incomplete command or a command with a null identifier 2 reject packets will be sent, one with the identifier and one with 0. Consuming the data of the command will prevent it. This allows to send a reject packet for each corrupted command in a multi-command packet.

Serdev recv_buf() callback is supposed to return the amount of bytes consumed, therefore an int in between 0 and count. Do not return negative number in case of issue, just print an error and return count. This fixes a WARN in ttyport_receive_buf().

Serdev recv_buf() callback is supposed to return the amount of bytes consumed, therefore an int in between 0 and count. Do not return a negative number in case of issue, just print an error and return count. Before this change, in case of error, the returned negative number was internally converted to 0 in ttyport_receive_buf, now when the receive buffer is corrupted we return the size of the whole received data (`count`). This should allow for better recovery in case receiver/transmitter get out of sync if some data is lost. This fixes a WARN in ttyport_receive_buf().
