| * MIPS: MSA: Fix a link error on `_init_msa_upper' with older GCCMaciej W. Rozycki2016-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit e49d38488515057dba8f0c2ba4cfde5be4a7281f upstream. Fix a build regression from commit c9017757c532 ("MIPS: init upper 64b of vector registers when MSA is first used"): arch/mips/built-in.o: In function `enable_restore_fp_context': traps.c:(.text+0xbb90): undefined reference to `_init_msa_upper' traps.c:(.text+0xbb90): relocation truncated to fit: R_MIPS_26 against `_init_msa_upper' traps.c:(.text+0xbef0): undefined reference to `_init_msa_upper' traps.c:(.text+0xbef0): relocation truncated to fit: R_MIPS_26 against `_init_msa_upper' to !CONFIG_CPU_HAS_MSA configurations with older GCC versions, which are unable to figure out that calls to `_init_msa_upper' are indeed dead. Of the many ways to tackle this failure choose the approach we have already taken in `thread_msa_context_live'. [ralf@linux-mips.org: Drop patch segment to junk file.] Signed-off-by: Maciej W.

| * MIPS: KVM: Fix timer IRQ race when writing CP0_CompareJames Hogan2016-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b45bacd2d048f405c7760e5cc9b60dd67708734f upstream. Writing CP0_Compare clears the timer interrupt pending bit (CP0_Cause.TI), but this wasn't being done atomically. If a timer interrupt raced with the write of the guest CP0_Compare, the timer interrupt could end up being pending even though the new CP0_Compare is nowhere near CP0_Count. We were already updating the hrtimer expiry with kvm_mips_update_hrtimer(), which used both kvm_mips_freeze_hrtimer() and kvm_mips_resume_hrtimer(). Close the race window by expanding out kvm_mips_update_hrtimer(), and clearing CP0_Cause.TI and setting CP0_Compare between the freeze and resume. Since the pending timer interrupt should not be cleared when CP0_Compare is written via the KVM user API, an ack argument is added to distinguish the source of the write.

| * MIPS: Fix buffer overflow in syscall_get_arguments()James Hogan2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit f4dce1ffd2e30fa31756876ef502ce6d2324be35 upstream. Since commit 4c21b8fd8f14 ("MIPS: seccomp: Handle indirect system calls (o32)"), syscall_get_arguments() attempts to handle o32 indirect syscall arguments by incrementing both the start argument number and the number of arguments to fetch. However only the start argument number needs to be incremented. The number of arguments does not change, they're just shifted up by one, and in fact the output array is provided by the caller and is likely only n entries long, so reading more arguments overflows the output buffer. In the case of seccomp, this results in it fetching 7 arguments starting at the 2nd one, which overflows the unsigned long args[6] in populate_seccomp_data(). This clobbers the $s0 register from syscall_trace_enter() which __seccomp_phase1_filter() saved onto the stack, into which syscall_trace_enter() had placed its syscall number argument. This caused Chromium to crash. Credit goes to Milko for tracking it down as far as $s0 being clobbered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When EVA is in use, __copy_from_user() was unconditionally using the EVA instructions to read the user address space, however this can also be used for kernel access. If the address isn't a valid user address it will cause an address error or TLB exception, and if it is then user memory may be read instead of kernel memory. For example in the following stack trace from Linux v3.10 (changes since then will prevent this particular one still happening) kernel_sendmsg() set the user address limit to KERNEL_DS, and tcp_sendmsg() goes on to use __copy_from_user() with a kernel address in KSeg0.

* MIPS: uaccess: Fix strlen_user with EVAJames Hogan2015-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | The strlen_user() function calls __strlen_kernel_asm in both branches of the eva_kernel_access() conditional. For EVA it should be calling __strlen_user_eva for user accesses, otherwise it will load from the kernel address space instead of the user address space, and the access checking will likely be ineffective at preventing it due to EVA's overlapping user and kernel address spaces. This was found after extending the test_user_copy module to cover user string access functions, which gave the following error with EVA: test_user_copy: illegal strlen_user passed Fortunately the use of strlen_user() has been all but eradicated from the mainline kernel, so only out of tree modules could be affected.

This is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below the VDSO data page. When a supported clocksource is not in use, the VDSO functions will return -ENOSYS, which causes libc to fall back on the standard syscall path. When support for neither of these clocksources is compiled into the kernel at all, the VDSO still provides clock_gettime(), as the coarse realtime/monotonic clocks can still be implemented. However, gettimeofday() is not provided in this case as nothing can be done without a suitable clocksource. This causes the symbol lookup to fail in libc and it will then always use the standard syscall path. This patch includes a workaround for a bug in QEMU which results in RDHWR on the CP0 count register always returning a constant (incorrect) value. A fix for this has been submitted, and the workaround can be removed after the fix has been in stable releases for a reasonable amount of time.

With this commit it does not export any symbols, it only replaces the current signal return trampoline page. A later commit will add user implementations of gettimeofday()/clock_gettime(). To support both new toolchains and old ones which don't generate ABI flags section, we define its content manually and then use a tool (genvdso) to patch up the section to have the correct name and type. genvdso also extracts symbol offsets ({,rt_}sigreturn) needed by the kernel, and generates a C file containing a "struct mips_vdso_image" containing both the VDSO data and these offsets. This C file is compiled into the kernel. On 64-bit kernels we require a different VDSO for each supported ABI, so we may build up to 3 different VDSOs. The VDSO to use is selected by the mips_abi structure. A kernel/user shared data page is created and mapped below the VDSO image. This is currently empty, but will be used by the user time function implementations which are added later. [markos.chandras@imgtec.com: - Add more comments - Move abi detection in genvdso.h since it's the get_symbol function that needs it. - Add an R6 specific way to calculate the base address of VDSO in order to avoid the branch instruction which affects performance. - Do not patch .gnu.attributes since it's not needed for dynamic linking. - Simplify Makefile a little bit. - checkpatch fixes - Restrict VDSO support for binutils < 2.25 for pre-R6 - Include atomic64.h for O32 variant on MIPS64] Signed-off-by: Alex Smith <alex.smith@imgtec.com> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: Matthew Fortune <matthew.fortune@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/11337/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This moves more Malta specific code to malta-dtshim.c, leaving the rest of the mti-malta code a little more board-agnostic. This will be useful to share more code between boards, with the device tree providing the board specifics as intended. Since we can't rely upon Malta boards running a bootloader capable of handling devictrees & filling in the required information, a piece of shim code (malta_dt_shim) is added to consume the (e)memsize variables provided as part of the bootloader environment (or on the kernel command line) then generate the DT memory node using the provided values.

What they actually couldn't handle was cases where there were less fill bits in the Entry{Lo,Hi} registers than bits used by software in PTEs. The handlers can now deal with this case, so enable RIXI for MIPS32 kernels on MIPS64 systems. Note that beyond the obvious benefits provided by having RIXI on such systems, this is required for systems implementing MIPSr6 where RIXI cannot be disabled. This reverts commit a68d09a156b2 ("MIPS: Don't use RI/XI with 32-bit kernels on 64-bit CPUs").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move all register definitions and structs into the driver. This allows us dropping the platform_data struct and drop any arch specific includes. Make use of different device names to identify the version of the block we have. Since we now have full control over the message width, we can drop the size check, which was broken anyway, since it never set ret to any error code. Also since we now have no arch depedendent resources, we can now allow compiling it for any arch, hidden behind COMPILE_TEST.
