Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Cross-merge bpf fixes after downstream PR. In particular to bring the fix in commitaa30eb3260("bpf: Force checkpoint when jmp history is too long"). The follow up verifier work depends on it. And the fix in commit6801cf7890("selftests/bpf: Use -4095 as the bad address for bits iterator"). It's fixing instability of BPF CI on s390 arch. No conflicts. Adjacent changes in: Auto-merging arch/Kconfig Auto-merging kernel/bpf/helpers.c Auto-merging kernel/bpf/memalloc.c Auto-merging kernel/bpf/verifier.c Auto-merging mm/slab_common.c Signed-off-by: Alexei Starovoitov <ast@kernel.org>

It is recommended to set access rights to file hierarchy leaves as much as
|
||||
possible. For instance, it is better to be able to have ``~/doc/`` as a

read-only hierarchy and ``~/tmp/`` as a read-write hierarchy, compared to
|
||||
``~/`` as a read-only hierarchy and ``~/tmp/`` as a read-write hierarchy.
|
||||
Following this good practice leads to self-sufficient hierarchies that do not
|
||||
depend on their location (i.e. parent directories). This is particularly
|
||||
relevant when we want to allow linking or renaming. Indeed, having consistent

access rights per directory enables to change the location of such directory

access rights per directory enables changing the location of such directories
|

without relying on the destination directory access rights (except those that
|
||||
are required for this operation, see ``LANDLOCK_ACCESS_FS_REFER``
|
||||
documentation).
|
||||
|
||||
Having self-sufficient hierarchies also helps to tighten the required access
|
||||
rights to the minimal set of data. This also helps avoid sinkhole directories,
|
||||
i.e. directories where data can be linked to but not linked from. However,

i.e. directories where data can be linked to but not linked from. However,

this depends on data organization, which might not be controlled by developers.

||||
access, would potentially allow to move ``~/tmp/`` to a non-readable directory

Unmapping, moving to another location, and shrinking the size,

via munmap() and mremap(), can leave an empty space, therefore

|
||||
The first set of syscalls to block is munmap, mremap, mmap. They can

either leave an empty space in the address space, therefore allowing

replacement with a new mapping with new set of attributes, or can

|

Moving or expanding a different VMA into the current location,

mprotect and pkey_mprotect are blocked because they changes the

protection bits (RWX) of the mapping.

Modifying a VMA via mmap(MAP_FIXED).
|

Certain destructive madvise behaviors, specifically MADV_DONTNEED,

MADV_FREE, MADV_DONTNEED_LOCKED, and MADV_WIPEONFORK, can introduce
|
||||
risks when applied to anonymous memory by threads lacking write
|

permissions. Consequently, these operations are prohibited under such
|
||||
conditions. The aforementioned behaviors have the potential to modify
|
||||
region contents by discarding pages, effectively performing a memset(0)
|
||||
operation on the anonymous memory.
|
||||
|
||||
Size expansion, via mremap(), does not appear to pose any
|

specific risks to sealed VMAs. It is included anyway because

the use case is unclear. In any case, users can rely on

Some destructive madvice() behaviors (e.g. MADV_DONTNEED)

for anonymous memory, when users don't have write permission to the

memory. Those behaviors can alter region contents by discarding pages,
|
||||
effectively a memset(0) for anonymous memory.
|
||||
- munmap: munmap is atomic. If one of VMAs in the given range is
|
||||
sealed, none of VMAs are updated.
|
||||
- mprotect, pkey_mprotect, madvise: partial update might happen, e.g.
|
||||
when mprotect over multiple VMAs, mprotect might update the beginning
|
||||
VMAs before reaching the sealed VMA and return -EPERM.
|
||||
- mmap and mremap: undefined behavior.

|

Kernel will return -EPERM for blocked operations.

|

For blocked operations, one can expect the given address is unmodified,

i.e. no partial update. Note, this is different from existing mm

|
||||
- mseal(ptr, 4096);
|
||||
- ret2 = mprotect(ptr, 8192, PROT_NONE);
|
||||
|
||||
ret1 will be -ENOMEM, the page from ptr is updated to PROT_READ.
|
||||
|
||||
ret2 will be -EPERM, the page remains to be PROT_READ.
|
||||
|
||||
**Note**:
|
||||
|
||||
- mseal() only works on 64-bit CPUs, not 32-bit CPU.
|
||||
|
||||
- users can call mseal() multiple times, mseal() on an already sealed memory
|
||||
is a no-action (not error).
|
||||
|
||||
- munseal() is not supported.

=========
|
||||
- glibc:
|
||||
The dynamic linker, during loading ELF executables, can apply sealing to
|
||||
non-writable memory segments.

Notes on which memory to seal:
|
||||
==============================
|
||||
|
||||
It might be important to note that sealing changes the lifetime of a mapping,
|
||||
i.e. the sealed mapping won’t be unmapped till the process terminates or the
|
||||
exec system call is invoked. Applications can apply sealing to any virtual
|
||||
memory region from userspace, but it is crucial to thoroughly analyze the
|
||||
mapping's lifetime prior to apply the sealing.
|
||||
When not to use mseal
|
||||
=====================
|
||||
Applications can apply sealing to any virtual memory region from userspace,
|
||||
but it is *crucial to thoroughly analyze the mapping's lifetime* prior to
|
||||
apply the sealing. This is because the sealed mapping *won’t be unmapped*
|
||||
until the process terminates or the exec system call is invoked.
|
||||
|
||||
For example:
|
||||
- aio/shm
|
||||
aio/shm can call mmap and munmap on behalf of userspace, e.g.
|
||||
ksys_shmdt() in shm.c. The lifetimes of those mapping are not tied to
|
||||
the lifetime of the process. If those memories are sealed from userspace,
|
||||
then munmap will fail, causing leaks in VMA address space during the
|
||||
lifetime of the process.
|
||||
|
||||
- aio/shm
|
||||
- ptr allocated by malloc (heap)
|
||||
Don't use mseal on the memory ptr return from malloc().
|
||||
malloc() is implemented by allocator, e.g. by glibc. Heap manager might
|
||||
allocate a ptr from brk or mapping created by mmap.
|
||||
If an app calls mseal on a ptr returned from malloc(), this can affect
|
||||
the heap manager's ability to manage the mappings; the outcome is
|
||||
non-deterministic.
|
||||
|
||||
aio/shm can call mmap()/munmap() on behalf of userspace, e.g. ksys_shmdt() in
|
||||
shm.c. The lifetime of those mapping are not tied to the lifetime of the
|
||||
process. If those memories are sealed from userspace, then munmap() will fail,
|
||||
causing leaks in VMA address space during the lifetime of the process.
|
||||
Example::
|
||||
|
||||
- Brk (heap)
|
||||
ptr = malloc(size);
|
||||
/* don't call mseal on ptr return from malloc. */
|
||||
mseal(ptr, size);
|
||||
/* free will success, allocator can't shrink heap lower than ptr */
|
||||
free(ptr);
|
||||
|
||||
Currently, userspace applications can seal parts of the heap by calling
|
||||
malloc() and mseal().
|
||||
let's assume following calls from user space:
|
||||
mseal doesn't block
|
||||
===================
|
||||
In a nutshell, mseal blocks certain mm syscall from modifying some of VMA's
|
||||
attributes, such as protection bits (RWX). Sealed mappings doesn't mean the
|
||||
memory is immutable.
|
||||
|
||||
- ptr = malloc(size);
|
||||
- mprotect(ptr, size, RO);
|
||||
- mseal(ptr, size);
|
||||
- free(ptr);
|
||||
|
||||
Technically, before mseal() is added, the user can change the protection of
|
||||
the heap by calling mprotect(RO). As long as the user changes the protection
|
||||
back to RW before free(), the memory range can be reused.
|
||||
|
||||
Adding mseal() into the picture, however, the heap is then sealed partially,
|
||||
the user can still free it, but the memory remains to be RO. If the address
|
||||
is re-used by the heap manager for another malloc, the process might crash
|
||||
soon after. Therefore, it is important not to apply sealing to any memory
|
||||
that might get recycled.
|
||||
|
||||
Furthermore, even if the application never calls the free() for the ptr,
|
||||
the heap manager may invoke the brk system call to shrink the size of the
|
||||
heap. In the kernel, the brk-shrink will call munmap(). Consequently,
|
||||
depending on the location of the ptr, the outcome of brk-shrink is
|
||||
nondeterministic.
|
||||
|
||||
|
||||
Additional notes:
|
||||
=================
|
||||
As Jann Horn pointed out in [3], there are still a few ways to write
|
||||
to RO memory, which is, in a way, by design. Those cases are not covered
|
||||
by mseal(). If applications want to block such cases, sandbox tools (such as
|
||||
seccomp, LSM, etc) might be considered.
|
||||
to RO memory, which is, in a way, by design. And those could be blocked
|
||||
by different security measures.
|
||||
|
||||
Those cases are:
|
||||
|
||||
- Write to read-only memory through /proc/self/mem interface.
|
||||
- Write to read-only memory through ptrace (such as PTRACE_POKETEXT).
|
||||
- userfaultfd.
|
||||
- Write to read-only memory through /proc/self/mem interface (FOLL_FORCE).
|
||||
- Write to read-only memory through ptrace (such as PTRACE_POKETEXT).
|
||||
- userfaultfd.
|
||||
|
||||
The idea that inspired this patch comes from Stephen Röttger’s work in V8
|
||||
CFI [4]. Chrome browser in ChromeOS will be the first user of this API.
