rin | Simplify fix for PR toolchain/57146
Introduce ARCH_STRIP_SYMBOLS variable to centralize logic for debug
symbols from MD Makefile's to Makefile.kern.inc.

rin | Fix kernel size inflation for arm and aarch64 (PR toolchain/57146)
For some conditions, SYSTEM_LD_TAIL is set for arm and aarch64.
Then, ctfmerge(1) in default SYSTEM_LD_TAIL is unintentionally
skipped, which results in the catastrophic kernel size inflation,
as reported in the PR.
Also, introduce and use OBJCOPY_STRIPFLAGS variable instead of
STRIPFLAGS, as strip(1) is replaced by objcopy(1) during MI
kernel build procedure.
XXX
For Makefile.{arm,aarch64}, weird logic is used to determine how
to handle debug symbols; MKDEBUG{,KERNEL} are taken into account
later in sys/conf/Makefile.kern.inc.

ryo | branches: 1.23.12;
In gcc10, -msign-return-address is no longer supported.
Instead, (LLVM-compatible) -mbranch-protection option is supported.

add support kernel profiling on aarch64
- add MCOUNT_ENTER, MCOUNT_EXIT macro
- __mcount() function should be aligned
- add "-fno-optimize-sibling-calls" option when PROF. for accurate profiling, it is better to suppress the tail call.
|
| 1.21 | 11-May-2020 |
ryo | branches: 1.21.2;
"options ARMV83_PAC" is now supported for gcc as well.
- add "-msign-return-address=all" to CFLAGS for gcc when specified options ARMV83_PAC
- AARCH64REG_{READ,WRITE}_INLINE3 macro can now use the APIAKey registers in both gcc and llvm.
llvm requires asm(".arch armv8.3-a"), whereas gcc requires __attribute__((target("arch=armv8.3-a"))).
- use ".arch armv8.3-a" rather than ".arch armv8.3-a+pac" in *.S for llvm.

| 1.20 | 13-Apr-2020 |
maxv | Add KASAN instrumentation on on-stack VLAs, same as amd64.
|
| 1.19 | 13-Apr-2020 |
maxv | Add support for Branch Target Identification (BTI).
On the executable pages that have the GP (Guarded Page) bit, the semantic
of the "br" and "blr" instructions is changed: the CPU expects the first
instruction of the jump/call target to be "bti", and faults if it isn't.
We add the GP bit on the kernel .text pages (and incidentally the .rodata
pages, but we don't care). The compiler adds a "bti c" instruction at the
beginning of each C function. We modify the ENTRY() macros to manually add
"bti c" in the asm functions.
cpuswitch.S needs a specific change: with "br x27" the CPU expects "bti j",
which is bad because the functions begin with "bti c"; switch to "br x16",
for the CPU to accept "bti c".
BTI helps defend against JOP/COP. Tested on Qemu.
|
| 1.18 | 12-Apr-2020 |
maxv | Add support for Pointer Authentication (PAC).
We use the "pac-ret" option, to sign the return instruction pointer on
function entry, and authenticate it on function exit. This acts as a
mitigation against ROP.
The authentication uses a per-lwp (secret) I-A key stored in the 128bit
APIAKey register and part of the lwp context. During lwp creation, the
kernel generates a random key, and during context switches, it installs
the key of the target lwp on the CPU.
Userland cannot read the APIAKey register directly. However, it can sign
its pointers with it, because the register is architecturally shared
between userland and the kernel. Although part of the CPU design, it is
a bit of an undesired behavior, because it allows to forge valid kernel
pointers from userland. To avoid that, we don't share the key with
userland, and rather switch it in EL0<->EL1 transitions. This means that
when userland executes, a different key is loaded in APIAKey than the one
the kernel uses. For now the userland key is a fixed 128bit zero value.
The DDB stack unwinder is changed to strip the authentication code from
the pointers in lr.
Two problems are known:
* Currently the idlelwps' keys are not really secret. This is because
the RNG is not yet available when we spawn these lwps. Not overly
important, but would be nice to fix with UEFI RNG.
* The key switching in EL0<->EL1 transitions is not the most optimized
code on the planet. Instead of checking aarch64_pac_enabled, it would
be better to hot-patch the code at boot time, but there currently is
no hot-patch support on aarch64.
Tested on Qemu.

the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked

pho | port-arm/58194: Resurrect vmt(4) from bitrot
On this architecture vmt(4) used to search for a node "/hypervisor" in the
FDT and probed the VMware hypervisor call only when the node was
found. However, things appear to have changed and VMware no longer provides
the FDT node.
Since vmt(4) doesn't actually need to read anything from FDT, and the
hypervisor call logically resides in virtual CPUs themselves, it would be
better to attach it directly to cpu, just like how it's probed on x86.

- removed any invalidation after freeing page tables due to
_pmap_sweep_pdp. This was never necessary afaict.
- all kernel mappings are marked global and userland mapping not-global.
Performance testing hasn't show a significant difference. The data here

disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.
The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.
The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.
Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!
The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.
Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

ryo | cleanup locore, and changed the way to map memories during boot.
- add functions bootpage_enter() and bootpage_alloc() to adapt various layout
of physical memory map. especially for 64bit physical memory layout.
pmapboot_alloc() allocates pagetable pages from _end[].
- changed to map only the required amount for PA=VA identity mapping
(kernel image, UART device, and FDT blob) with L2_BLOCK(2Mbyte).
- changing page permission for kernel image, and making KSEG mapping are done
at cpu_kernel_vm_init() instead of at locore.
- optimize PTE entries with PTE Contiguous bit. it is enabled on devmap only for now.
reviewed by skrll@, thanks.

nia | Remove uscanner(4) driver
This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

maya | remove urio(4), a driver for the Rio500 MP3 player.
At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.
Renamed all major entries to obsolete, as was done in previous removals.
This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?
Proposed on tech-kern a month ago.

dholland | branches: 1.4.6;
Systematize handling of removed drivers.
- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.
Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.
Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)

maxv | Remove ISDN from the kernel. It has remained unmaintained for a long time,
is of poor quality, and is now an obstacle to MP-ification. It was removed
ten years ago from FreeBSD for the same reason.
This retires a big user of the mbuf API, and will ease maintenance of the
kernel.
