      ioremap: Update pgtable free interfaces with addr · 6e6b6377
      Chintan Pandya authored 
      commit 785a19f9 upstream.

The following kernel panic was observed on ARM64 platform due to a stale
TLB entry.

 1. ioremap with 4K size, a valid pte page table is set.
 2. iounmap it, its pte entry is set to 0.
 3. ioremap the same address with 2M size, update its pmd entry with
    a new value.
 4. CPU may hit an exception because the old pmd entry is still in TLB,
    which leads to a kernel panic.

Commit b6bdb751 ("mm/vmalloc: add interfaces to free unmapped page
table") has addressed this panic by falling to pte mappings in the above
case on ARM64.

To support pmd mappings in all cases, TLB purge needs to be performed
in this case on ARM64.

Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page()
so that TLB purge can be added later in seprate patches.

      Bluetooth: hidp: buffer overflow in hidp_process_report · 7c7940ff
      Mark Salyzyn authored 
      commit 7992c188 upstream.

CVE-2018-9363

The buffer length is unsigned at all layers, but gets cast to int and
checked in hidp_process_report and can lead to a buffer overflow.
Switch len parameter to unsigned int to resolve issue.

This affects 3.18 and newer kernels.

      ASoC: Intel: cht_bsw_max98090_ti: Fix jack initialization · 5daf2471
      Thierry Escande authored 
      commit 3bbda5a3 upstream.

If the ts3a227e audio accessory detection hardware is present and its
driver probed, the jack needs to be created before enabling jack
detection in the ts3a227e driver. With this patch, the jack is
instantiated in the max98090 headset init function if the ts3a227e is
present. This fixes a null pointer dereference as the jack detection
enabling function in the ts3a driver was called before the jack is
created.

      crypto: ablkcipher - fix crash flushing dcache in error path · b7c2b699
      Eric Biggers authored 
      commit 318abdfb upstream.

Like the skcipher_walk and blkcipher_walk cases:

scatterwalk_done() is only meant to be called after a nonzero number of
bytes have been processed, since scatterwalk_pagedone() will flush the
dcache of the *previous* page.  But in the error case of
ablkcipher_walk_done(), e.g. if the input wasn't an integer number of
blocks, scatterwalk_done() was actually called after advancing 0 bytes.
This caused a crash ("BUG: unable to handle kernel paging request")
during '!PageSlab(page)' on architectures like arm and arm64 that define
ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE, provided that the input was
page-aligned as in that case walk->offset == 0.

Fix it by reorganizing ablkcipher_walk_done() to skip the
scatterwalk_advance() and scatterwalk_done() if an error has occurred.

      crypto: vmac - separate tfm and request context · 81ad8a8e
      Eric Biggers authored 
      commit bb296481 upstream.

syzbot reported a crash in vmac_final() when multiple threads
concurrently use the same "vmac(aes)" transform through AF_ALG.  The bug
is pretty fundamental: the VMAC template doesn't separate per-request
state from per-tfm (per-key) state like the other hash algorithms do,
but rather stores it all in the tfm context.  That's wrong.

Also, vmac_final() incorrectly zeroes most of the state including the
derived keys and cached pseudorandom pad.  Therefore, only the first
VMAC invocation with a given key calculates the correct digest.

Fix these bugs by splitting the per-tfm state from the per-request state
and using the proper init/update/final sequencing for requests.

Reproducer for the crash:

    #include <linux/if_alg.h>
    #include <sys/socket.h>
    #include <unistd.h>

    int main()
    {
            int fd;
            struct sockaddr_alg addr = {
                    .salg_type = "hash",
                    .salg_name = "vmac(aes)",
            };
            char buf[256] = { 0 };

            fd = socket(AF_ALG, SOCK_SEQPACKET, 0);
            bind(fd, (void *)&addr, sizeof(addr));
            setsockopt(fd, SOL_ALG, ALG_SET_KEY, buf, 16);
            fork();
            fd = accept(fd, NULL, NULL);
            for (;;)
                    write(fd, buf, 256);
    }

The immediate cause of the crash is that vmac_ctx_t.partial_size exceeds
VMAC_NHBYTES, causing vmac_final() to memset() a negative length.

      crypto: vmac - require a block cipher with 128-bit block size · 371c35cb
      Eric Biggers authored 
      commit 73bf20ef upstream.

The VMAC template assumes the block cipher has a 128-bit block size, but
it failed to check for that.  Thus it was possible to instantiate it
using a 64-bit block size cipher, e.g. "vmac(cast5)", causing
uninitialized memory to be used.

Add the needed check when instantiating the template.

      crypto: x86/sha256-mb - fix digest copy in sha256_mb_mgr_get_comp_job_avx2() · e87485a5

sometimes calculates the wrong digest.  Fix it.

            .salg_name = "sha256_mb",
        };
        __u8 data[4096] = { 0 };
        __u8 digest[32];
        int ret;
        int i;

        fd = socket(AF_ALG, SOCK_SEQPACKET, 0);
        bind(fd, (void *)&addr, sizeof(addr));
        fork();
        fd = accept(fd, 0, 0);
        do {
            ret = write(fd, data, 4096);
            assert(ret == 4096);
            ret = read(fd, digest, 32);
            assert(ret == 32);
        } while (memcmp(digest, expected, 32) == 0);

        printf("wrong digest: ");
        for (i = 0; i < 32; i++)
            printf("%02x", digest[i]);
        printf("\n");
    }

Output was:

      kasan: don't emit builtin calls when sanitization is off · 76b6f30f
      Andrey Konovalov authored 
      commit 0e410e15 upstream.

With KASAN enabled the kernel has two different memset() functions, one
with KASAN checks (memset) and one without (__memset).  KASAN uses some
macro tricks to use the proper version where required.  For example
memset() calls in mm/slub.c are without KASAN checks, since they operate
on poisoned slab object metadata.

The issue is that clang emits memset() calls even when there is no
memset() in the source code.  They get linked with improper memset()
implementation and the kernel fails to boot due to a huge amount of KASAN
reports during early boot stages.

The solution is to add -fno-builtin flag for files with KASAN_SANITIZE :=
n marker.

      x86/mm: Disable ioremap free page handling on x86-PAE · 2130e543
      Toshi Kani authored 
      commit f967db0b upstream.

ioremap() supports pmd mappings on x86-PAE.  However, kernel's pmd
tables are not shared among processes on x86-PAE.  Therefore, any
update to sync'd pmd entries need re-syncing.  Freeing a pte page
also leads to a vmalloc fault and hits the BUG_ON in vmalloc_sync_one().

Disable free page handling on x86-PAE.  pud_free_pmd_page() and
pmd_free_pte_page() simply return 0 if a given pud/pmd entry is present.
This assures that ioremap() does not update sync'd pmd entries at the
cost of falling back to pte mappings.

      x86: i8259: Add missing include file · cc83ba49
      Guenter Roeck authored 
      commit 0a957467 upstream.

i8259.h uses inb/outb and thus needs to include asm/io.h to avoid the
following build error, as seen with x86_64:defconfig and CONFIG_SMP=n.

  In file included from drivers/rtc/rtc-cmos.c:45:0:
  arch/x86/include/asm/i8259.h: In function 'inb_pic':
  arch/x86/include/asm/i8259.h:32:24: error:
	implicit declaration of function 'inb'

  arch/x86/include/asm/i8259.h: In function 'outb_pic':
  arch/x86/include/asm/i8259.h:45:2: error:
	implicit declaration of function 'outb'
