v5.15 backport request

by Ard Biesheuvel

Please consider the commits below for backporting to v5.15. These patches are prerequisites for the backport of the x86 EFI stub refactor that is needed for distros to sign v5.15 images for secure boot in a way that complies with new MS requirements for memory protections while running in the EFI firmware. All patches either predate v6.1 or have been backported to it already. The remaining ~50 changes will be posted as a patch series in due time, as they will not apply cleanly to v5.15. Please apply in the order that they appear below. Thanks, Ard. 44f155b4b07b8293472c9797d5b39839b91041ca 4da87c51705815fe1fbd41cc61640bb80da5bc54 7c4146e8885512719a50b641e9277a1712e052ff 176db622573f028f85221873ea4577e096785315 950d00558a920227b5703d1fcc4751cfe03853cd ec1c66af3a30d45c2420da0974c01d3515dba26e a9ee679b1f8c3803490ed2eeffb688aaee56583f 3ba75c1316390b2bc39c19cb8f0f85922ab3f9ed 82e0d6d76a2a74bd6a31141d555d53b4cc22c2a3 31f1a0edff78c43e8a3bd3692af0db1b25c21b17 9cf42bca30e98a1c6c9e8abf876940a551eaa3d1 cb8bda8ad4438b4bcfcf89697fc84803fb210017 e2ab9eab324cdf240de89741e4a1aa79919f0196 5c3a85f35b583259cf5ca0344cd79c8899ba1bb7 91592b5c0c2f076ff9d8cc0c14aa563448ac9fc4 73a6dec80e2acedaef3ca603d4b5799049f6e9f8 7f22ca396778fea9332d83ec2359dbe8396e9a06 4b52016247aeaa55ca3e3bc2e03cd91114c145c2 630f337f0c4fd80390e8600adcab31550aea33df db14655ad7854b69a2efda348e30d02dbc19e8a1 bad267f9e18f8e9e628abd1811d2899b1735a4e1 62b71cd73d41ddac6b1760402bbe8c4932e23531 cc3fdda2876e58a7e83e558ab51853cf106afb6a d2d7a54f69b67cd0a30e0ebb5307cb2de625baac

[PATCH 2/2] x86/sgx: Resolve EREMOVE page vs EAUG page data race

by Dmitrii Kuvaiskii

Two enclave threads may try to add and remove the same enclave page simultaneously (e.g., if the SGX runtime supports both lazy allocation and `MADV_DONTNEED` semantics). Consider this race: 1. T1 performs page removal in sgx_encl_remove_pages() and stops right after removing the page table entry and right before re-acquiring the enclave lock to EREMOVE and xa_erase(&encl->page_array) the page. 2. T2 tries to access the page, and #PF[not_present] is raised. The condition to EAUG in sgx_vma_fault() is not satisfied because the page is still present in encl->page_array, thus the SGX driver assumes that the fault happened because the page was swapped out. The driver continues on a code path that installs a page table entry *without* performing EAUG. 3. The enclave page metadata is in inconsistent state: the PTE is installed but there was no EAUG. Thus, T2 in userspace infinitely receives SIGSEGV on this page (and EACCEPT always fails). Fix this by making sure that T1 (the page-removing thread) always wins this data race. In particular, the page-being-removed is marked as such, and T2 retries until the page is fully removed.

[PATCH 1/2] x86/sgx: Resolve EAUG race where losing thread returns SIGBUS

by Dmitrii Kuvaiskii

Two enclave threads may try to access the same non-present enclave page simultaneously (e.g., if the SGX runtime supports lazy allocation). The threads will end up in sgx_encl_eaug_page(), racing to acquire the enclave lock. The winning thread will perform EAUG, set up the page table entry, and insert the page into encl->page_array. The losing thread will then get -EBUSY on xa_insert(&encl->page_array) and proceed to error handling path. This error handling path contains two bugs: (1) SIGBUS is sent to userspace even though the enclave page is correctly installed by another thread, and (2) sgx_encl_free_epc_page() is called that performs EREMOVE even though the enclave page was never intended to be removed. The first bug is less severe because it impacts only the user space; the second bug is more severe because it also impacts the OS state by ripping the page (added by the winning thread) from the enclave. Fix these two bugs (1) by returning VM_FAULT_NOPAGE to the generic Linux fault handler so that no signal is sent to userspace, and (2) by replacing sgx_encl_free_epc_page() with sgx_free_epc_page() so that no EREMOVE is performed.

[PATCH v1] usb: typec: tcpm: enforce ready state when queueing alt mode vdm

by RD Babiera

Before sending Enter Mode for an Alt Mode, there is a gap between Discover Modes and the Alt Mode driver queueing the Enter Mode VDM for the port partner to send a message to the port. If this message results in unregistering Alt Modes such as in a DR_SWAP, then the following deadlock can occur with respect to the DisplayPort Alt Mode driver: 1. The DR_SWAP state holds port->lock. Unregistering the Alt Mode driver results in a cancel_work_sync() that waits for the current dp_altmode_work to finish. 2. dp_altmode_work makes a call to tcpm_altmode_enter. The deadlock occurs because tcpm_queue_vdm_unlock attempts to hold port->lock. Before attempting to grab the lock, ensure that the port is in a state vdm_run_state_machine can run in. Alt Mode unregistration will not occur in these states.

[REGRESSION] Serious regression on 6.1.x-stable caused by "bounds: support non-power-of-two CONFIG_NR_CPUS"

by Mikhail Novosyolov

Hello, colleagues. Commit f2d5dcb48f7ba9e3ff249d58fc1fa963d374e66a "bounds: support non-power-of-two CONFIG_NR_CPUS" (https://github.com/torvalds/linux/commit/f2d5dcb48f7ba9e3ff249d58fc1fa963d3…) was backported to 6.1.x-stable (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…), but causes a serious regression on quite a lot of hardware with AMD GPUs, kernel panics. It was backported to 6.1.84, 6.1.84 has problems, 6.1.83 does not, the newest 6.1.88 still has this problem. The problem is described here: https://gitlab.freedesktop.org/drm/amd/-/issues/3347 #regzbot introduced: 428ca0000f0abd5c99354c52a36becf2b815ca21

[PATCH 1/1] serial: sc16is7xx: announce support of SER_RS485_RTS_ON_SEND

by Konstantin Pugin

From: Konstantin Pugin <ria.freelander(a)gmail.com> When specifying flag SER_RS485_RTS_ON_SEND in RS485 configuration, we get the following warning after commit 4afeced55baa ("serial: core: fix sanitizing check for RTS settings"): invalid RTS setting, using RTS_AFTER_SEND instead This results in SER_RS485_RTS_AFTER_SEND being set and the driver always write to the register field SC16IS7XX_EFCR_RTS_INVERT_BIT, which breaks some hardware using these chips. The hardware supports both RTS_ON_SEND and RTS_AFTER_SEND modes, so fix this by announcing support for RTS_ON_SEND.
