MIPS: math-emu: Remove pr_err() calls from fpu_emu()
The FPU emulator includes 2 calls to pr_err() which are triggered by
invalid instruction encodings for MIPSr6 cmp.cond.fmt instructions.
These cases are not kernel errors, merely invalid instructions which are
already handled by delivering a SIGILL which will provide notification
that something failed in cases where that makes sense.
In cases where that SIGILL is somewhat expected & being handled, for
example when crashme happens to generate one of the affected bad
encodings, the message is printed with no useful context about what
triggered it & spams the kernel log for no good reason.
Remove the pr_err() calls to make crashme run silently & treat the bad
encodings the same way we do others, with a SIGILL & no further kernel
log output.

MIPS: Fix generic-board-config.sh for builds using O=
When configuring the kernel using one of the generic MIPS defconfig
targets, the generic-board-config.sh script is used to check
requirements listed in board config fragments against a reference config
in order to determine which board config fragments to merge into the
final config.
When specifying O= to configure in a directory other than the kernel
source directory, this generic-board-config.sh script is invoked in the
directory that we are configuring in (ie. the directory that O equals),
and the path to the reference config is relative to the current
directory. The script then changes the current directory to the source
tree, which unfortunately breaks later access to the reference file
since its path is relative to a directory that is no longer the current
working directory. This results in configuration failing with errors
such as:
$ make ARCH=mips O=tmp 32r2_defconfig
make[1]: Entering directory '/home/pburton/src/linux/tmp'
Using ../arch/mips/configs/generic_defconfig as base
Merging ../arch/mips/configs/generic/32r2.config
Merging ../arch/mips/configs/generic/eb.config
grep: ./.config.32r2_defconfig: No such file or directory
grep: ./.config.32r2_defconfig: No such file or directory
The base file '.config' does not exist. Exit.
make[1]: *** [arch/mips/Makefile:505: 32r2_defconfig] Error 1
make[1]: Leaving directory '/home/pburton/src/linux-ingenic/tmp'
make: *** [Makefile:145: sub-make] Error 2
Fix this by avoiding changing the working directory in
generic-board-config.sh, instead using full paths to files under
$(srctree)/ where necessary.

MIPS: bpf: Fix uninitialised target compiler error
Compiling ebpf_jit.c with gcc 4.9 results in a (likely spurious)
compiler warning, as gcc has detected that the variable "target" may be
used uninitialised. Since -Werror is active, this is treated as an error
and causes a kernel build failure whenever CONFIG_MIPS_EBPF_JIT is
enabled.
arch/mips/net/ebpf_jit.c: In function 'build_one_insn':
arch/mips/net/ebpf_jit.c:1118:80: error: 'target' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
emit_instr(ctx, j, target);
^
cc1: all warnings being treated as errors
Fix this by initialising "target" to 0. If it really is used
uninitialised this would result in a jump to 0 and a detectable run time
failure.

MIPS: Fix input modify in __write_64bit_c0_split()
The inline asm in __write_64bit_c0_split() modifies the 64-bit input operand by shifting the high register left by 32, and constructing the full 64-bit value in the low register (even on a 32-bit kernel), so if that value is used again it could cause breakage as GCC would assume the registers haven't changed when they have. To quote the GCC extended asm documentation: > Warning: Do not modify the contents of input-only operands (except for > inputs tied to outputs). The compiler assumes that on exit from the > asm statement these operands contain the same values as they had > before executing the statement. Avoid modifying the input by using a temporary variable as an output which is modified instead of the input and not otherwise used. The asm is always __volatile__ so GCC shouldn't optimise it out. The low register of the temporary output is written before the high register of the input is read, so we have two constraint alternatives, one where both use the same registers (for when the input value isn't subsequently used), and one with an early clobber on the output in case the low output uses the same register as the high input. This allows the resulting assembly to remain mostly unchanged. A diff of a MIPS32r6 kernel reveals only three differences, two in relation to write_c0_r10k_diag() in cpu_probe() (register allocation rearranged slightly but otherwise identical), and one in relation to write_c0_cvmmemctl2() in kvm_vz_local_flush_guesttlb_all(), but the octeon CPU is only supported on 64-bit kernels where __write_64bit_c0_split() isn't used so that shouldn't matter in practice. So there currently doesn't appear to be anything broken by this bug.

Pull namespace updates from Eric Biederman: "Life has been busy and I have not gotten half as much done this round as I would have liked. I delayed it so that a minor conflict resolution with the mips tree could spend a little time in linux-next before I sent this pull request. This includes two long delayed user namespace changes from Kirill Tkhai. It also includes a very useful change from Serge Hallyn that allows the security capability attribute to be used inside of user namespaces. The practical effect of this is people can now untar tarballs and install rpms in user namespaces. It had been suggested to generalize this and encode some of the namespace information information in the xattr name. Upon close inspection that makes the things that should be hard easy and the things that should be easy more expensive. Then there is my bugfix/cleanup for signal injection that removes the magic encoding of the siginfo union member from the kernel internal si_code. The mips folks reported the case where I had used FPE_FIXME me is impossible so I have remove FPE_FIXME from mips, while at the same time including a return statement in that case to keep gcc from complaining about unitialized variables. I almost finished the work to get make copy_siginfo_to_user a trivial copy to user. The code is available at: git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3 But I did not have time/energy to get the code posted and reviewed before the merge window opened. I was able to see that the security excuse for just copying fields that we know are initialized doesn't work in practice there are buggy initializations that don't initialize the proper fields in siginfo.

vga: optimise console scrolling
Where possible, call memset16(), memmove() or memcpy() instead of using open-coded loops. I don't like the calling convention that uses a byte count instead of a count of u16s, but it's a little late to change that. Reduces code size of fbcon.o by almost 400 bytes on my laptop build.

Merge branch 'kvm-ppc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
This fix was intended for 4.13, but didn't get in because both maintainers were on vacation. Paul Mackerras: "It adds mutual exclusion between list_add_rcu and list_del_rcu calls on the kvm->arch.spapr_tce_tables list. Without this, userspace could potentially trigger corruption of the list and cause a host crash or worse." |

mm,fork: introduce MADV_WIPEONFORK
Introduce MADV_WIPEONFORK semantics, which result in a VMA being empty in the child process after fork. This differs from MADV_DONTFORK in one important way. If a child process accesses memory that was MADV_WIPEONFORK, it will get zeroes. The address ranges are still valid, they are just empty. If a child process accesses memory that was MADV_DONTFORK, it will get a segmentation fault, since those address ranges are no longer valid in the child after fork. Since MADV_DONTFORK also seems to be used to allow very large programs to fork in systems with strict memory overcommit restrictions, changing the semantics of MADV_DONTFORK might break existing programs. MADV_WIPEONFORK only works on private, anonymous VMAs. The use case is libraries that store or cache information, and want to know that they need to regenerate it in the child process after fork. Examples of this would be: - systemd/pulseaudio API checks (fail after fork) (replacing a getpid check, which is too slow without a PID cache) - PKCS#11 API reinitialization check (mandated by specification) - glibc's upcoming PRNG (reseed after fork) - OpenSSL PRNG (reseed after fork) The security benefits of a forking server having a re-inialized PRNG in every child process are pretty obvious. However, due to libraries having all kinds of internal state, and programs getting compiled with many different versions of each library, it is unreasonable to expect calling programs to re-initialize everything manually after fork. A further complication is the proliferation of clone flags, programs bypassing glibc's functions to call clone directly, and programs calling unshare, causing the glibc pthread_atfork hook to not get called. It would be better to have the kernel take care of this automatically. The patch also adds MADV_KEEPONFORK, to undo the effects of a prior MADV_WIPEONFORK.

mm: arch: consolidate mmap hugetlb size encodings
A non-default huge page size can be encoded in the flags argument of the mmap system call. The definitions for these encodings are in arch specific header files. However, all architectures use the same values. Consolidate all the definitions in the primary user header file (uapi/linux/mman.h). Include definitions for all known huge page sizes. Use the generic encoding definitions in hugetlb_encode.h as the basis for these definitions.

MIPS: Stacktrace: Fix microMIPS stack unwinding on big endian systems
The stack unwinding code uses the mips_instuction union to decode the
instructions it finds. That union uses the __BITFIELD_FIELD macro to
reorder depending on endianness. The stack unwinding code always places
16bit instructions in halfword 1 of the union. This makes the union
accesses correct for little endian systems. Similarly, 32bit
instructions are reordered such that they are correct for little endian
systems. This handling leaves unwinding the stack on big endian systems
broken, as the mips_instruction union will then look for the fields in
the wrong halfword.
To fix this, use a logical shift to place the 16bit instruction into the
correct position in the word field of the union. Use the same shifting
to order the 2 halfwords of 32bit instuctions. Then replace accesses to
the halfword with accesses to the shifted word.
In the case of the ADDIUS5 instruction, switch to using the
mm16_r5_format union member to avoid the need for a 16bit shift.

MIPS: microMIPS: Fix decoding of swsp16 instruction
When the immediate encoded in the instruction is accessed, it is sign
extended due to being a signed value being assigned to a signed integer.
The ISA specifies that this operation is an unsigned operation.
The sign extension leads us to incorrectly decode:
801e9c8e: cbf1 sw ra,68(sp)
As having an immediate of 1073741809.
Since the instruction format does not specify signed/unsigned, and this
is currently the only location to use this instuction format, change it
to an unsigned immediate.

MIPS: microMIPS: Fix detection of addiusp instruction
The addiusp instruction uses the pool16d opcode, with bit 0 of the
immediate set. The test for the addiusp opcode erroneously did a logical
and of the immediate with mm_addiusp_func, which has value 1, so this
test always passes when the immediate is non-zero.
Fix the test by replacing the logical and with a bitwise and.

mips: Save all registers when saving the frame
The MIPS frame save code was just saving a few registers, enough to do a backtrace if every function set up a frame. However, this is not working if you are using DWARF unwinding, because most of the registers are wrong. This was causing kdump backtraces to be short or bogus. So save all the registers.

MIPS: Make SAVE_SOME more standard
Modify the SAVE_SOME macro to look more like a standard function, doing the arithmetic for the frame on the SP register instead of copying it from K1, and by saving the stored EPC from the RA. This lets the get_frame_info() function process this function like any other. It also remove an instruction or two from the kernel entry, making it more efficient. unwind_stack_by_address() has special handling for the top of the interrupt stack, but without this change unwinding will still fail if you get an interrupt while handling an interrupt and try to do a traceback from the second interrupt. This change modifies the get_saved_sp macro to optionally store the fetched value right into sp and store the old SP value into K0. Then it's just a matter of subtracting the frame from SP and storing the old SP from K0. This required changing the DADDI workaround a bit, since K0 holds the SP, we had to use K1 for AT. But it eliminated some of the special handling for the DADDI workaround. Saving the RA register was moved up to before fetching the CP0_EPC register, so the CP0_EPC register could be stored into RA and the saved. This lets the traceback code know where RA is actually stored.

MIPS: Fix issues in backtraces
I saw two problems when doing backtraces: The compiler was putting a "fast return" at the top of some functions, before it set up the frame. The backtrace code would stop when it saw a jump instruction, so it would never get to the stack frame setup and would thus misinterpret it. To fix this, don't look for jump instructions until the frame setup has been seen. The assembly code here is: ffffffff80b885a0 <serial8250_handle_irq>: ffffffff80b885a0: c8a00003 bbit0 a1,0x0,ffffffff80b885b0 <serial8250_handle_irq+0x10> ffffffff80b885a4: 0000102d move v0,zero ffffffff80b885a8: 03e00008 jr ra ffffffff80b885ac: 00000000 nop ffffffff80b885b0: 67bdffd0 daddiu sp,sp,-48 ffffffff80b885b4: ffb00008 sd s0,8(sp) The second problem was the compiler was putting the last instruction of the frame save in the delay slot of the jump instruction. If it saved the RA in there, the backtrace could would miss it and misinterpret the frame. To fix this, make sure to process the instruction after the first jump seen. The assembly code for this is: ffffffff80806fd0 <plat_irq_dispatch>: ffffffff80806fd0: 67bdffd0 daddiu sp,sp,-48 ffffffff80806fd4: ffb30020 sd s3,32(sp) ffffffff80806fd8: 24130018 li s3,24 ffffffff80806fdc: ffb20018 sd s2,24(sp) ffffffff80806fe0: 3c12811c lui s2,0x811c ffffffff80806fe4: ffb10010 sd s1,16(sp) ffffffff80806fe8: 3c11811c lui s1,0x811c ffffffff80806fec: ffb00008 sd s0,8(sp) ffffffff80806ff0: 3c10811c lui s0,0x811c ffffffff80806ff4: 08201c03 j ffffffff8080700c <plat_irq_dispa tch+0x3c> ffffffff80806ff8: ffbf0028 sd ra,40(sp) Signed-off-by: Corey Minyard <cminyard@mvista.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/16992/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |
