2022-03-08arm64: Ensure execute-only permissions are not allowed without EPANCatalin Marinas
Commit 18107f8a2df6 ("arm64: Support execute-only permissions with Enhanced PAN") re-introduced execute-only permissions when EPAN is available. When EPAN is not available, arch_filter_pgprot() is supposed to change a PAGE_EXECONLY permission into PAGE_READONLY_EXEC. However, if BTI or MTE are present, such check does not detect the execute-only pgprot in the presence of PTE_GP (BTI) or MT_NORMAL_TAGGED (MTE), allowing the user to request PROT_EXEC with PROT_BTI or PROT_MTE. Remove the arch_filter_pgprot() function, change the default VM_EXEC permissions to PAGE_READONLY_EXEC and update the protection_map[] array at core_initcall() if EPAN is detected.

In commit: 114945d84a30a5fe ("arm64: Fix labels in el2_setup macros") We renamed a label from '1' to '.Lskip_gicv3_\@', but failed to update a branch to it, which now targets a later label also called '1'. The branch is taken rarely, when GICv3 is present but SRE is disabled at EL3, causing a boot-time crash. Update the caller to the new label name.

2022-02-09ACPI/IORT: Check node revision for PMCG resourcesRobin Murphy
The original version of the IORT PMCG definition had an oversight wherein there was no way to describe the second register page for an implementation using the recommended RELOC_CTRS feature. Although the spec was fixed, and the final patches merged to ACPICA and Linux written against the new version, it seems that some old firmware based on the original revision has survived and turned up in the wild. Add a check for the original PMCG definition, and avoid filling in the second memory resource with nonsense if so. Otherwise it is likely that something horrible will happen when the PMCG driver attempts to probe.

2022-01-27arm64: errata: Add detection for TRBE invalid prohibited statesAnshuman Khandual
TRBE implementations affected by Arm erratum #2038923 might get TRBE into an inconsistent view on whether trace is prohibited within the CPU. As a result, the trace buffer or trace buffer state might be corrupted. This happens after TRBE buffer has been enabled by setting TRBLIMITR_EL1.E, followed by just a single context synchronization event before execution changes from a context, in which trace is prohibited to one where it isn't, or vice versa. In these mentioned conditions, the view of whether trace is prohibited is inconsistent between parts of the CPU, and the trace buffer or the trace buffer state might be corrupted.

2022-01-26arm64: extable: fix load_unaligned_zeropad() reg indicesEvgenii Stepanov
In ex_handler_load_unaligned_zeropad() we erroneously extract the data and addr register indices from ex->type rather than ex->data. As ex->type will contain EX_TYPE_LOAD_UNALIGNED_ZEROPAD (i.e. 4): * We'll always treat X0 as the address register, since EX_DATA_REG_ADDR is extracted from bits [9:5]. Thus, we may attempt to dereference an arbitrary address as X0 may hold an arbitrary value. * We'll always treat X4 as the data register, since EX_DATA_REG_DATA is extracted from bits [4:0]. Thus we will corrupt X4 and cause arbitrary behaviour within load_unaligned_zeropad() and its caller. Fix this by extracting both values from ex->data as originally intended. On an MTE-enabled QEMU image we are hitting the following crash: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Call trace: fixup_exception+0xc4/0x108 __do_kernel_fault+0x3c/0x268 do_tag_check_fault+0x3c/0x104 do_mem_abort+0x44/0xf4 el1_abort+0x40/0x64 el1h_64_sync_handler+0x60/0xa0 el1h_64_sync+0x7c/0x80 link_path_walk+0x150/0x344 path_openat+0xa0/0x7dc do_filp_open+0xb8/0x168 do_sys_openat2+0x88/0x17c __arm64_sys_openat+0x74/0xa0 invoke_syscall+0x48/0x148 el0_svc_common+0xb8/0xf8 do_el0_svc+0x28/0x88 el0_svc+0x24/0x84 el0t_64_sync_handler+0x88/0xec el0t_64_sync+0x1b4/0x1b8 Code: f8695a69 71007d1f 540000e0 927df12a (f940014a) Fixes: 753b32368705 ("arm64: extable: add load_unaligned_zeropad() handler") Cc: <stable@vger.kernel.org> # 5.16.x Reviewed-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Evgenii Stepanov <eugenis@google.com> Link: https://lore.kernel.org/r/20220125182217.2605202-1-eugenis@google.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2022-01-23ftrace: Fix assuming build time sort works for s390Steven Rostedt (Google)
To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

2022-01-22perf evsel: Override attr->sample_period for non-libpfm4 eventsGerman Gomez
A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
