Revert "ANDROID: Kbuild, LLVMLinux: allow overriding clang target triple"
This reverts commit e145f7b103.

AOSP's distribution of GNU binutils always had a curious target triple
prefix on the binaries.  Now that GNU binutils is deprecated for Android
Common Kernels, we can now remove this out of tree workaround. Now
building Android kernels with LLVM matches upstream (see
Documentation/kbuild/llvm.rst).

ANDROID: move builds to use gas prebuilts
Completes stage 5 of:
https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/master/BINUTILS_KERNEL_DEPRECATION.md

Bug: 141693040
Test: remove host binutils (easy for cross compiling, hard for host
tools), rebuild multiple configs including cuttlefish configs which rely
on these.

FROMLIST: arm64: vdso32: Allow ld.lld to properly link the VDSO
As it stands now, the vdso32 Makefile hardcodes the linker to ld.bfd
using -fuse-ld=bfd with $(CC). This was taken from the arm vDSO
Makefile, as the comment notes, done in commit d2b30cd4b7 ("ARM:
8384/1: VDSO: force use of BFD linker").

Commit fe00e50b2d ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to
link VDSO") changed that Makefile to use $(LD) directly instead of
through $(CC), which matches how the rest of the kernel operates. Since
then, LD=ld.lld means that the arm vDSO will be linked with ld.lld,
which has shown no problems so far.

Allow ld.lld to link this vDSO as we do the regular arm vDSO. To do
this, we need to do a few things:

* Add a LD_COMPAT variable, which defaults to $(CROSS_COMPILE_COMPAT)ld
  with gcc and $(LD) if LLVM is 1, which will be ld.lld, or
  $(CROSS_COMPILE_COMPAT)ld if not, which matches the logic of the main
  Makefile. It is overrideable for further customization and avoiding
  breakage.

* Eliminate cc32-ldoption, which matches commit 055efab312 ("kbuild:
  drop support for cc-ldoption").

With those, we can use $(LD_COMPAT) in cmd_ldvdso and change the flags
from compiler linker flags to linker flags directly. We eliminate
-mfloat-abi=soft because it is not handled by the linker.

ANDROID: use arm-linux-androidkernel- for CROSS_COMPILE_COMPAT
While ultimately resulting in the same binary being used, this allows
the arm64 compat vdso to use the same target triple as an ARCH=arm build
for Android.

This means that arm-linux-androideabi-elfedit doesn't need to be created
in: https://android.googlesource.com/platform/prebuilts/gas/linux-x86/.

FROMLIST: x86/boot: allow a relocatable kernel to be linked with lld
LLD by default disallows relocations in read-only segments. For a
relocatable kernel, we pass -z notext to the linker to explicitly
allow relocations. This behavior is the default for BFD.

482efd771f UPSTREAM: mm/mremap: hold the rmap lock in write mode when moving page table entries.
commit 97113eb39fa7972722ff490b947d8af023e1f6a2 upstream.

To avoid a race between rmap walk and mremap, mremap does
take_rmap_locks().  The lock was taken to ensure that rmap walk don't miss
a page table entry due to PTE moves via move_pagetables().  The kernel
does further optimization of this lock such that if we are going to find
the newly added vma after the old vma, the rmap lock is not taken.  This
is because rmap walk would find the vmas in the same order and if we don't
find the page table attached to older vma we would find it with the new
vma which we would iterate later.

As explained in commit eb66ae0308 ("mremap: properly flush TLB before
releasing the page") mremap is special in that it doesn't take ownership
of the page.  The optimized version for PUD/PMD aligned mremap also
doesn't hold the ptl lock.  This can result in stale TLB entries as show
below.

This patch updates the rmap locking requirement in mremap to handle the race condition
explained below with optimized mremap::

Optmized PMD move

    CPU 1                           CPU 2                                   CPU 3

    mremap(old_addr, new_addr)      page_shrinker/try_to_unmap_one

    mmap_write_lock_killable()

                                    addr = old_addr
                                    lock(pte_ptl)
    lock(pmd_ptl)
    pmd = *old_pmd
    pmd_clear(old_pmd)
    flush_tlb_range(old_addr)

    *new_pmd = pmd
                                                                            *new_addr = 10; and fills
                                                                            TLB with new addr
                                                                            and old pfn

    unlock(pmd_ptl)
                                    ptep_clear_flush()
                                    old pfn is free.
                                                                            Stale TLB entry

Optimized PUD move also suffers from a similar race.  Both the above race
condition can be fixed if we force mremap path to take rmap lock.

c262d21607 FROMLIST: binder: fix UAF of alloc->vma in race with munmap()
In commit 720c241924 ("ANDROID: binder: change down_write to
down_read") binder assumed the mmap read lock is sufficient to protect
alloc->vma inside binder_update_page_range(). This used to be accurate
until commit dd2283f260 ("mm: mmap: zap pages with read mmap_sem in
munmap"), which now downgrades the mmap_lock after detaching the vma
from the rbtree in munmap(). Then it proceeds to teardown and free the
vma with only the read lock held.

This means that accesses to alloc->vma in binder_update_page_range() now
will race with vm_area_free() in munmap() and can cause a UAF as shown
in the following KASAN trace:

  ==================================================================

To prevent the race above, revert back to taking the mmap write lock
inside binder_update_page_range(). One might expect an increase of mmap
lock contention. However, binder already serializes these calls via top
level alloc->mutex. Also, there was no performance impact shown when
running the binder benchmark tests.

Note this patch is specific to stable branches 5.4 and 5.10. Since in
newer kernel releases binder no longer caches a pointer to the vma.
Instead, it has been refactored to use vma_lookup() which avoids the
issue described here. This switch was introduced in commit a43cfc87caaf
("android: binder: stop saving a pointer to the VMA").

6d1487a4aa UPSTREAM: mm: Fix TLB flush for not-first PFNMAP mappings in unmap_region()
This is a stable-specific patch.
I botched the stable-specific rewrite of
commit b67fbebd4cf98 ("mmu_gather: Force tlb-flush VM_PFNMAP vmas"):
As Hugh pointed out, unmap_region() actually operates on a list of VMAs,
and the variable "vma" merely points to the first VMA in that list.
So if we want to check whether any of the VMAs we're operating on is
PFNMAP or MIXEDMAP, we have to iterate through the list and check each VMA.

4a5337dfb3 UPSTREAM: mm: Force TLB flush for PFNMAP mappings before unlink_file_vma()
commit b67fbebd4cf980aecbcc750e1462128bffe8ae15 upstream.

Some drivers rely on having all VMAs through which a PFN might be
accessible listed in the rmap for correctness.
However, on X86, it was possible for a VMA with stale TLB entries
to not be listed in the rmap.

This was fixed in mainline with
commit b67fbebd4cf9 ("mmu_gather: Force tlb-flush VM_PFNMAP vmas"),
but that commit relies on preceding refactoring in
commit 18ba064e42df3 ("mmu_gather: Let there be one tlb_{start,end}_vma()
implementation") and commit 1e9fdf21a4339 ("mmu_gather: Remove per arch
tlb_{start,end}_vma()").

This patch provides equivalent protection without needing that
refactoring, by forcing a TLB flush between removing PTEs in
unmap_vmas() and the call to unlink_file_vma() in free_pgtables().

40a8e0ed5c UPSTREAM: wifi: cfg80211: fix u8 overflow in cfg80211_update_notlisted_nontrans()
commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.

In the copy code of the elements, we do the following calculation
to reach the end of the MBSSID element:

	/* copy the IEs after MBSSID */
	cpy_len = mbssid[1] + 2;

This looks fine, however, cpy_len is a u8, the same as mbssid[1],
so the addition of two can overflow. In this case the subsequent
memcpy() will overflow the allocated buffer, since it copies 256
bytes too much due to the way the allocation and memcpy() sizes
are calculated.

Fix this by using size_t for the cpy_len variable.

This fixes CVE-2022-41674.

commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.

Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
and the minimum is 1 since a multiple BSSID set with just one BSSID
doesn't make sense (the # of BSSIDs is limited by 2^n).

Limit this in the parsing in both cfg80211 and mac80211, rejecting
any elements with an invalid value.

This fixes potentially bad shifts in the processing of these inside
the cfg80211_gen_new_bssid() function later.

I found this during the investigation of CVE-2022-41674 fixed by the
previous patch.

commit 567e14e39e8f8c6997a1378bc3be615afca86063 upstream.

When iterating the elements here, ensure the length byte is
present before checking it to see if the entire element will
fit into the buffer.

Longer term, we should rewrite this code using the type-safe
element iteration macros that check all of this.

916a29b486 UPSTREAM: wifi: cfg80211: fix BSS refcounting bugs
commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.

There are multiple refcounting bugs related to multi-BSSID:
 - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
   the bss pointer is overwritten before checking for the
   transmitted BSS, which is clearly wrong. Fix this by using
   the bss_from_pub() macro.

 - In cfg80211_bss_update() we copy the transmitted_bss pointer
   from tmp into new, but then if we release new, we'll unref
   it erroneously. We already set the pointer and ref it, but
   need to NULL it since it was copied from the tmp data.

 - In cfg80211_inform_single_bss_data(), if adding to the non-
   transmitted list fails, we unlink the BSS and yet still we
   return it, but this results in returning an entry without
   a reference. We shouldn't return it anyway if it was broken
   enough to not get added there.

This fixes CVE-2022-42720.

commit bcca852027e5878aec911a347407ecc88d6fff7f upstream.

If a non-transmitted BSS shares enough information (both
SSID and BSSID!) with another non-transmitted BSS of a
different AP, then we can find and update it, and then
try to add it to the non-transmitted BSS list. We do a
search for it on the transmitted BSS, but if it's not
there (but belongs to another transmitted BSS), the list
gets corrupted.

Since this is an erroneous situation, simply fail the
list insertion in this case and free the non-transmitted
BSS.

This fixes CVE-2022-42721.

commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.

When updating beacon elements in a non-transmitted BSS,
also update the hidden sub-entries to the same beacon
elements, so that a future update through other paths
won't trigger a WARN_ON().

The warning is triggered because the beacon elements in
the hidden BSSes that are children of the BSS should
always be the same as in the parent.

There's no need to parse all elements etc. just to find the
authentication challenge - use cfg80211_find_elem() instead.
This also allows us to remove WLAN_EID_CHALLENGE handling

9f3b5ab822 UPSTREAM: wifi: mac80211: fix MBSSID parsing use-after-free
Commit ff05d4b45dd89b922578dac497dcabf57cf771c6 upstream.
This is a different version of the commit, changed to store
the non-transmitted profile in the elems, and freeing it in
the few places where it's relevant, since that is only the
case when the last argument for parsing (the non-tx BSSID)
is non-NULL.

When we parse a multi-BSSID element, we might point some
element pointers into the allocated nontransmitted_profile.
However, we free this before returning, causing UAF when the
relevant pointers in the parsed elements are accessed.

Fix this by not allocating the scratch buffer separately but
as part of the returned structure instead, that way, there
are no lifetime issues with it.

The scratch buffer introduction as part of the returned data
here is taken from MLO feature work done by Ilan.

This fixes CVE-2022-42719.

9267f98065 UPSTREAM: hardening: Avoid harmless Clang option under CONFIG_INIT_STACK_ALL_ZERO
Currently under Clang, CC_HAS_AUTO_VAR_INIT_ZERO requires an extra
-enable flag compared to CC_HAS_AUTO_VAR_INIT_PATTERN. GCC 12[1] will
not, and will happily ignore the Clang-specific flag. However, its
presence on the command-line is both cumbersome and confusing. Due to
GCC's tolerant behavior, though, we can continue to use a single Kconfig
cc-option test for the feature on both compilers, but then drop the
Clang-specific option in the Makefile.

In other words, this patch does not change anything other than making the
compiler command line shorter once GCC supports -ftrivial-auto-var-init=zero.
