arm64: mte: move register initialization to C
[ Upstream commit 973b9e37330656dec719ede508e4dc40e5c2d80c ]
If FEAT_MTE2 is disabled via the arm64.nomte command line argument on a
CPU that claims to support FEAT_MTE2, the kernel will use Tagged Normal
in the MAIR. If we interpret arm64.nomte to mean that the CPU does not
in fact implement FEAT_MTE2, setting the system register like this may
lead to UNSPECIFIED behavior. Fix it by arranging for MAIR to be set
in the C function cpu_enable_mte which is called based on the sanitized
version of the system register.
There is no need for the rest of the MTE-related system register
initialization to happen from assembly, with the exception of TCR_EL1,
which must be set to include at least TBI1 because the secondary CPUs
access KASan-allocated data structures early. Therefore, make the TCR_EL1
initialization unconditional and move the rest of the initialization to
cpu_enable_mte so that we no longer have a dependency on the unsanitized
ID register value.

arm64: mte: Ensure the cleared tags are visible before setting the PTE
commit 1d0cb4c8864addc362bae98e8ffa5500c87e1227 upstream.
As an optimisation, only pages mapped with PROT_MTE in user space have
the MTE tags zeroed. This is done lazily at the set_pte_at() time via
mte_sync_tags(). However, this function is missing a barrier and another
CPU may see the PTE updated before the zeroed tags are visible. Add an
smp_wmb() barrier if the mapping is Normal Tagged.

FROMGIT: arm64/mte: Remove asymmetric mode from the prctl() interface
As pointed out by Evgenii Stepanov one potential issue with the new ABI for enabling asymmetric is that if there are multiple places where MTE is configured in a process, some of which were compiled with the old prctl.h and some of which were compiled with the new prctl.h, there may be problems keeping track of which MTE modes are requested. For example some code may disable only sync and async modes leaving asymmetric mode enabled when it intended to fully disable MTE. In order to avoid such mishaps remove asymmetric mode from the prctl(), instead implicitly allowing it if both sync and async modes are requested. This should not disrupt userspace since a process requesting both may already see a mix of sync and async modes due to differing defaults between CPUs or changes in default while the process is running but it does mean that userspace is unable to explicitly request asymmetric mode without changing the system default for CPUs.

FROMLIST: arm64/mte: Add userspace interface for enabling asymmetric mode
The architecture provides an asymmetric mode for MTE where tag mismatches are checked asynchronously for reads but synchronously for loads. Allow userspace processes to select this and make it available as a default mode via the existing per-CPU sysfs interface. Since there PR_MTE_TCF_ values are a bitmask (allowing the kernel to choose between the multiple modes) and there are no free bits adjacent to the existing PR_MTE_TCF_ bits the set of bits used to specify the mode becomes disjoint. Programs using the new interface should be aware of this and programs that do not use it will not see any change in behaviour. When userspace requests two possible modes but the system default for the CPU is the third mode (eg, default is synchronous but userspace requests either asynchronous or asymmetric) the preference order is: ASYMM > ASYNC > SYNC This situation is not currently possible since there are only two modes and it is mandatory to have a system default so there could be no ambiguity and there is no ABI change. The chosen order is basically arbitrary as we do not have a clear metric for what is better here. If userspace requests specifically asymmetric mode via the prctl() and the system does not support it then we will return an error, this mirrors how we handle the case where userspace enables MTE on a system that does not support MTE at all and the behaviour that will be seen if running on an older kernel that does not support userspace use of asymmetric mode. Attempts to set asymmetric mode as the default mode will result in an error if the system does not support it.

UPSTREAM: arm64: mte: Add asymmetric mode support
MTE provides an asymmetric mode for detecting tag exceptions. In particular, when such a mode is present, the CPU triggers a fault on a tag mismatch during a load operation and asynchronously updates a register when a tag mismatch is detected during a store operation. Add support for MTE asymmetric mode. Note: If the CPU does not support MTE asymmetric mode the kernel falls back on synchronous mode which is the default for kasan=on.

UPSTREAM: arm64: kasan: mte: move GCR_EL1 switch to task switch when KASAN disabled
It is not necessary to write to GCR_EL1 on every kernel entry and exit when HW tag-based KASAN is disabled because the kernel will not execute any IRG instructions in that mode. Since accessing GCR_EL1 can be expensive on some microarchitectures, avoid doing so by moving the access to task switch when HW tag-based KASAN is disabled.

arm64: add MTE supported check to thread switching and syscall entry/exit
This lets us avoid doing unnecessary work on hardware that does not
support MTE, and will allow us to freely use MTE instructions in the
code called by mte_thread_switch().
Since this would mean that we do a redundant check in
mte_check_tfsr_el1(), remove it and add two checks now required in its
callers. This also avoids an unnecessary DSB+ISB sequence on the syscall
exit path for hardware not supporting MTE.

arm64: kasan: mte: remove redundant mte_report_once logic
We have special logic to suppress MTE tag check fault reporting, based on a global `mte_report_once` and `reported` variables. These can be used to suppress calling kasan_report() when taking a tag check fault, but do not prevent taking the fault in the first place, nor does they affect the way we disable tag checks upon taking a fault. The core KASAN code already defaults to reporting a single fault, and has a `multi_shot` control to permit reporting multiple faults. The only place we transiently alter `mte_report_once` is in lib/test_kasan.c, where we also the `multi_shot` state as the same time. Thus `mte_report_once` and `reported` are redundant, and can be removed. When a tag check fault is taken, tag checking will be disabled by `do_tag_recovery` and must be explicitly re-enabled if desired. The test code does this by calling kasan_enable_tagging_sync(). This patch removes the redundant mte_report_once() logic and associated variables.

arm64: kasan: mte: use a constant kernel GCR_EL1 value
When KASAN_HW_TAGS is selected, KASAN is enabled at boot time, and the hardware supports MTE, we'll initialize `kernel_gcr_excl` with a value dependent on KASAN_TAG_MAX. While the resulting value is a constant which depends on KASAN_TAG_MAX, we have to perform some runtime work to generate the value, and have to read the value from memory during the exception entry path. It would be better if we could generate this as a constant at compile-time, and use it as such directly. Early in boot within __cpu_setup(), we initialize GCR_EL1 to a safe value, and later override this with the value required by KASAN. If CONFIG_KASAN_HW_TAGS is not selected, or if KASAN is disabeld at boot time, the kernel will not use IRG instructions, and so the initial value of GCR_EL1 is does not matter to the kernel. Thus, we can instead have __cpu_setup() initialize GCR_EL1 to a value consistent with KASAN_TAG_MAX, and avoid the need to re-initialize it during hotplug and resume form suspend. This patch makes arem64 use a compile-time constant KERNEL_GCR_EL1 value, which is compatible with KASAN_HW_TAGS when this is selected. This removes the need to re-initialize GCR_EL1 dynamically, and acts as an optimization to the entry assembly, which no longer needs to load this value from memory. The redundant initialization hooks are removed. In order to do this, KASAN_TAG_MAX needs to be visible outside of the core KASAN code. To do this, I've moved the KASAN_TAG_* values into <linux/kasan-tags.h>. There should be no functional change as a result of this patch.

arm64: move preemption disablement to prctl handlers
In the next patch, we will start reading sctlr_user from mte_update_sctlr_user and subsequently writing a new value based on the task's TCF setting and potentially the per-CPU TCF preference. This means that we need to be careful to disable preemption around any code sequences that read from sctlr_user and subsequently write to sctlr_user and/or SCTLR_EL1, so that we don't end up writing a stale value (based on the previous CPU's TCF preference) to either of them. We currently have four such sequences, in the prctl handlers for PR_SET_TAGGED_ADDR_CTRL and PR_PAC_SET_ENABLED_KEYS, as well as in the task initialization code that resets the prctl settings. Change the prctl handlers to disable preemption in the handlers themselves rather than the functions that they call, and change the task initialization code to call the respective prctl handlers instead of setting sctlr_user directly. As a result of this change, we no longer need the helper function set_task_sctlr_el1, nor does its behavior make sense any more, so remove it.

arm64: Introduce prctl(PR_PAC_{SET,GET}_ENABLED_KEYS)
This change introduces a prctl that allows the user program to control which PAC keys are enabled in a particular task. The main reason why this is useful is to enable a userspace ABI that uses PAC to sign and authenticate function pointers and other pointers exposed outside of the function, while still allowing binaries conforming to the ABI to interoperate with legacy binaries that do not sign or authenticate pointers. The idea is that a dynamic loader or early startup code would issue this prctl very early after establishing that a process may load legacy binaries, but before executing any PAC instructions. This change adds a small amount of overhead to kernel entry and exit due to additional required instruction sequences. On a DragonBoard 845c (Cortex-A75) with the powersave governor, the overhead of similar instruction sequences was measured as 4.9ns when simulating the common case where IA is left enabled, or 43.7ns when simulating the uncommon case where IA is disabled. These numbers can be seen as the worst case scenario, since in more realistic scenarios a better performing governor would be used and a newer chip would be used that would support PAC unlike Cortex-A75 and would be expected to be faster than Cortex-A75. On an Apple M1 under a hypervisor, the overhead of the entry/exit instruction sequences introduced by this patch was measured as 0.3ns in the case where IA is left enabled, and 33.0ns in the case where IA is disabled.

arm64: mte: Enable async tag check fault
MTE provides a mode that asynchronously updates the TFSR_EL1 register when a tag check exception is detected. To take advantage of this mode the kernel has to verify the status of the register at: 1. Context switching 2. Return to user/EL0 (Not required in entry from EL0 since the kernel did not run) 3. Kernel entry from EL1 4. Kernel exit to EL1 If the register is non-zero a trace is reported. Add the required features for EL1 detection and reporting. Note: ITFSB bit is set in the SCTLR_EL1 register hence it guaranties that the indirect writes to TFSR_EL1 are synchronized at exception entry to EL1. On the context switch path the synchronization is guarantied by the dsb() in __switch_to(). The dsb(nsh) in mte_check_tfsr_exit() is provisional pending confirmation by the architects.

load_unaligned_zeropad() and __get/put_kernel_nofault() functions can read past some buffer limits which may include some MTE granule with a different tag.

Enable Tag Check Override (TCO) in these functions before the load and disable it afterwards to prevent this to happen. Note: The same condition can be hit in MTE sync mode but we deal with it through the exception handling.

A newly created (PROT_MTE) mapping points to the zero page which had its

arm64: kasan: allow enabling in-kernel MTE
Hardware tag-based KASAN relies on Memory Tagging Extension (MTE) feature and requires it to be enabled. MTE supports This patch adds a new mte_enable_kernel() helper, that enables MTE in Synchronous mode in EL1 and is intended to be called from KASAN runtime during initialization. The Tag Checking operation causes a synchronous data abort as a consequence of a tag check fault when MTE is configured in synchronous mode. As part of this change enable match-all tag for EL1 to allow the kernel to access user pages without faulting. This is required because the kernel does not have knowledge of the tags set by the user in a page. Note: For MTE, the TCF bit field in SCTLR_EL1 affects only EL1 in a similar way as TCF0 affects EL0. MTE that is built on top of the Top Byte Ignore (TBI) feature hence we enable it as part of this patch as well.

arm64: mte: reset the page tag in page->flags
The hardware tag-based KASAN for compatibility with the other modes stores the tag associated to a page in page->flags. Due to this the kernel faults on access when it allocates a page with an initial tag and the user changes the tags. Reset the tag associated by the kernel to a page in all the meaningful places to prevent kernel faults on access. Note: An alternative to this approach could be to modify page_to_virt(). This though could end up being racy, in fact if a CPU checks the PG_mte_tagged bit and decides that the page is not tagged but another CPU maps the same with PROT_MTE and becomes tagged the subsequent kernel access would fail.

arm64: mte: add in-kernel MTE helpers
Provide helper functions to manipulate allocation and pointer tags for kernel addresses. Low-level helper functions (mte_assign_*, written in assembly) operate tag values from the [0x0, 0xF] range. High-level helper functions (mte_get/set_*) use the [0xF0, 0xFF] range to preserve compatibility with normal kernel pointers that have 0xFF in their top byte. MTE_GRANULE_SIZE and related definitions are moved to mte-def.h header that doesn't have any dependencies and is safe to include into any low-level header.

arm64: mte: fix prctl(PR_GET_TAGGED_ADDR_CTRL) if TCF0=NONE
Previously we were always returning a tag inclusion mask of zero via
PR_GET_TAGGED_ADDR_CTRL if TCF0 was set to NONE. Fix it by making
the code for the NONE case match the others.

arm64: mte: Enable swap of tagged pages
When swapping pages out to disk it is necessary to save any tags that have been set, and restore when swapping back in. Make use of the new page flag (PG_ARCH_2, locally named PG_mte_tagged) to identify pages with tags. When swapping out these pages the tags are stored in memory and later restored when the pages are brought back in. Because shmem can swap pages back in without restoring the userspace PTE it is also necessary to add a hook for shmem.

arm64: mte: ptrace: Add PTRACE_{PEEK,POKE}MTETAGS support
Add support for bulk setting/getting of the MTE tags in a tracee's address space at 'addr' in the ptrace() syscall prototype. 'data' points to a struct iovec in the tracer's address space with iov_base representing the address of a tracer's buffer of length iov_len. The tags to be copied to/from the tracer's buffer are stored as one tag per byte. On successfully copying at least one tag, ptrace() returns 0 and updates the tracer's iov_len with the number of tags copied. In case of error, either -EIO or -EFAULT is returned, trying to follow the ptrace() man page. Note that the tag copying functions are not performance critical, therefore they lack optimisations found in typical memory copy routines.

arm64: mte: Allow user control of the generated random tags via prctl()
The IRG, ADDG and SUBG instructions insert a random tag in the resulting address. Certain tags can be excluded via the GCR_EL1.Exclude bitmap when, for example, the user wants a certain colour for freed buffers. Since the GCR_EL1 register is not accessible at EL0, extend the prctl(PR_SET_TAGGED_ADDR_CTRL) interface to include a 16-bit field in the first argument for controlling which tags can be generated by the above instruction (an include rather than exclude mask). Note that by default all non-zero tags are excluded. This setting is per-thread. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> |

arm64: mte: Allow user control of the tag check mode via prctl()
By default, even if PROT_MTE is set on a memory range, there is no tag check fault reporting (SIGSEGV). Introduce a set of option to the exiting prctl(PR_SET_TAGGED_ADDR_CTRL) to allow user control of the tag check fault mode: PR_MTE_TCF_NONE - no reporting (default) PR_MTE_TCF_SYNC - synchronous tag check fault reporting PR_MTE_TCF_ASYNC - asynchronous tag check fault reporting These options translate into the corresponding SCTLR_EL1.TCF0 bitfield, context-switched by the kernel. Note that the kernel accesses to the user address space (e.g. read() system call) are not checked if the user thread tag checking mode is PR_MTE_TCF_NONE or PR_MTE_TCF_ASYNC. If the tag checking mode is PR_MTE_TCF_SYNC, the kernel makes a best effort to check its user address accesses, however it cannot always guarantee it.

arm64: mte: Tags-aware aware memcmp_pages() implementation
When the Memory Tagging Extension is enabled, two pages are identical only if both their data and tags are identical. Make the generic memcmp_pages() a __weak function and add an arm64-specific implementation which returns non-zero if any of the two pages contain valid MTE tags (PG_mte_tagged set). There isn't much benefit in comparing the tags of two pages since these are normally used for heap allocations and likely to differ anyway.

arm64: mte: Clear the tags when a page is mapped in user-space with PROT_MTE
Pages allocated by the kernel are not guaranteed to have the tags zeroed, especially as the kernel does not (yet) use MTE itself. To ensure the user can still access such pages when mapped into its address space, clear the tags via set_pte_at(). A new page flag - PG_mte_tagged (PG_arch_2) - is used to track pages with valid allocation tags. Since the zero page is mapped as pte_special(), it won't be covered by the above set_pte_at() mechanism. Clear its tags during early MTE initialisation.

arm64: mte: Handle synchronous and asynchronous tag check faults
The Memory Tagging Extension has two modes of notifying a tag check fault at EL0, configurable through the SCTLR_EL1.TCF0 field: 1. Synchronous raising of a Data Abort exception with DFSC 17. 2. Asynchronous setting of a cumulative bit in TFSRE0_EL1. Add the exception handler for the synchronous exception and handling of the asynchronous TFSRE0_EL1.TF0 bit setting via a new TIF flag in do_notify_resume(). On a tag check failure in user-space, whether synchronous or asynchronous, a SIGSEGV will be raised on the faulting thread.
