2023-02-07RISC-V: KVM: Redirect illegal instruction traps to guestAndy Chiu1-0/+6
The M-mode redirects an unhandled illegal instruction trap back to S-mode. However, KVM running in HS-mode terminates the VS-mode software when it receives illegal instruction trap. Instead, KVM should redirect the illegal instruction trap back to VS-mode, and let VS-mode trap handler decide the next step. This futher allows guest kernel to implement on-demand enabling of vector extension for a guest user space process upon first-use.

At the moment, riscv only supports PMD and PUD hugepages. For sv39, PGDIR_SIZE == PUD_SIZE but not for sv48 and sv57. So fix this by changing PGDIR_SIZE into PUD_SIZE.

2023-02-07KVM: nVMX: Simplify the setting of SECONDARY_EXEC_ENABLE_VMFUNC for nested.Yu Zhang1-9/+5
Values of base settings for nested proc-based VM-Execution control MSR come from the ones for non-nested. And for SECONDARY_EXEC_ENABLE_VMFUNC flag, KVM currently a) first mask off it from vmcs_conf->cpu_based_2nd_exec_ctrl; b) then check it against the same source; c) and reset it again if host has it. So just simplify this, by not masking off SECONDARY_EXEC_ENABLE_VMFUNC in the first place. No functional change.

2023-02-04KVM: x86/emulator: Fix segment load privilege level validationMichal Luczaj1-2/+2
Intel SDM describes what steps are taken by the CPU to verify if a memory segment can actually be used at a given privilege level. Loading DS/ES/FS/GS involves checking segment's type as well as making sure that neither selector's RPL nor caller's CPL are greater than segment's DPL. Emulator implements Intel's pseudocode in __load_segment_descriptor(), even quoting the pseudocode in the comments. Although the pseudocode is correctly translated, the implementation is incorrect. This is most likely due to SDM, at the time, being wrong. Patch fixes emulator's logic and updates the pseudocode in the comment. Below are historical notes. Emulator code for handling segment descriptors appears to have been introduced in March 2010 in commit 38ba30ba51a0 ("KVM: x86 emulator: Emulate task switch in emulator.c"). Intel SDM Vol 2A: Instruction Set Reference, A-M (Order Number: 253666-034US, _March 2010_) lists the steps for loading segment registers in section related to MOV instruction: IF DS, ES, FS, or GS is loaded with non-NULL selector THEN IF segment selector index is outside descriptor table limits or segment is not a data or readable code segment or ((segment is a data or nonconforming code segment) and (both RPL and CPL > DPL)) <--- THEN #GP(selector); FI; This is precisely what __load_segment_descriptor() quotes and implements. But there's a twist; a few SDM revisions later (253667-044US), in August 2012, the snippet above becomes: IF DS, ES, FS, or GS is loaded with non-NULL selector THEN IF segment selector index is outside descriptor table limits or segment is not a data or readable code segment or ((segment is a data or nonconforming code segment) [note: missing or superfluous parenthesis?] or ((RPL > DPL) and (CPL > DPL)) <--- THEN #GP(selector); FI; Many SDMs later (253667-065US), in December 2017, pseudocode reaches what seems to be its final form: IF DS, ES, FS, or GS is loaded with non-NULL selector THEN IF segment selector index is outside descriptor table limits OR segment is not a data or readable code segment OR ((segment is a data or nonconforming code segment) AND ((RPL > DPL) or (CPL > DPL))) <--- THEN #GP(selector); FI; which also matches the behavior described in AMD's APM, which states that a #GP occurs if: The DS, ES, FS, or GS register was loaded and the segment pointed to was a data or non-conforming code segment, but the RPL or CPL was greater than the DPL.

When iterating on a linked list, a result of memremap is dereferenced without checking it for NULL. This patch adds a check that falls back on allocating a new page in case memremap doesn't succeed.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 fixes from Heiko Carstens: - With CONFIG_VMAP_STACK enabled it is not possible to load the s390 specific diag288_wdt watchdog module. The reason is that a pointer to a string is passed to an inline assembly; this string however is located on the stack, while the instruction within the inline assembly expects a physicial address. Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call. Otherwise the kernel image decompressor may corrupt/overwrite an initrd. This was reported to happen on s390 after commit 2aa14b1ab2c4 ("zstd: import usptream v1.5.2"). * tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: specify __decompress() buf len to avoid overflow watchdog: diag288_wdt: fix __diag288() inline assembly watchdog: diag288_wdt: do not use stack buffers for hardware data

2023-02-02net: mediatek: sgmii: ensure the SGMII PHY is powered down on configurationAlexander Couzens2-11/+30
The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was taken from a good working state of the SGMII interface.
