2a11b3bfc5 arm64: dts: qcom: sdm630: Drop flags for mdss irqs
The number of interrupt cells for the mdss interrupt controller is 1,
meaning there should only be one cell for the interrupt number, not two.
Drop the second cell containing (unused) irq flags.

2da376228a ext4: limit length to bitmap_maxbytes - blocksize in punch_hole
Syzbot found an issue [1] in ext4_fallocate().
The C reproducer [2] calls fallocate(), passing size 0xffeffeff000ul,
and offset 0x1000000ul, which, when added together exceed the
bitmap_maxbytes for the inode. This triggers a BUG in
ext4_ind_remove_space(). According to the comments in this function
the 'end' parameter needs to be one block after the last block to be
removed. In the case when the BUG is triggered it points to the last
block. Modify the ext4_punch_hole() function and add constraint that
caps the length to satisfy the one before laster block requirement.

ext4_search_dir:

  de = (struct ext4_dir_entry_2 *)search_buf;
  dlimit = search_buf + buf_size;
  while ((char *) de < dlimit) {
  ...
    if ((char *) de + de->name_len <= dlimit &&

      return -1;
    offset += de_len;
    de = (struct ext4_dir_entry_2 *) ((char *) de + de_len);
  }

Assume:
de=0xffff8881317c2fff
dlimit=0x0xffff8881317c3000

If read 'de->name_len' which address is 0xffff8881317c3005, obviously is
out of range, then will trigger use-after-free.
To solve this issue, 'dlimit' must reserve 8 bytes, as we will read
'de->name_len' to judge if '(char *) de + de->name_len' out of range.

a2b0b205d1 ext4: fix symlink file size not match to file content
We got issue as follows:
[home]# fsck.ext4  -fn  ram0yb
e2fsck 1.45.6 (20-Mar-2020)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Symlink /p3/d14/d1a/l3d (inode #3494) is invalid.
Clear? no
Entry 'l3d' in /p3/d14/d1a (3383) has an incorrect filetype (was 7, should be 0).
Fix? no

As the symlink file size does not match the file content. If the writeback
of the symlink data block failed, ext4_finish_bio() handles the end of IO.
However this function fails to mark the buffer with BH_write_io_error and
so when unmount does journal checkpoint it cannot detect the writeback
error and will cleanup the journal. Thus we've lost the correct data in the
journal area. To solve this issue, mark the buffer as BH_write_io_error in
ext4_finish_bio().

ad5cd4f4ee ext4: fix fallocate to use file_modified to update permissions consistently
Since the initial introduction of (posix) fallocate back at the turn of
the century, it has been possible to use this syscall to change the
user-visible contents of files.  This can happen by extending the file
size during a preallocation, or through any of the newer modes (punch,
zero, collapse, insert range).  Because the call can be used to change
file contents, we should treat it like we do any other modification to a
file -- update the mtime, and drop set[ug]id privileges/capabilities.

The VFS function file_modified() does all this for us if pass it a
locked inode, so let's make fallocate drop permissions correctly.

35ee1f4990 cxl/mem: Replace redundant debug message with a comment
cxl_mem_probe() already emits a log message when HDM operation can not
be established. Delete the similar one in cxl_hdm_decode_init().

What is less obvious is why global_ctrl being enabled makes positive
values of info->ranges irrelevant, and the Linux behavior with respect

Decoder Base + Size registers.

cxl_dvsec_decode_init() is tasked with checking whether legacy DVSEC
range based decode is in effect, or whether HDM can be enabled / already
is enabled. As such it either succeeds or fails and that result is the
return value. The @do_hdm_init variable is misleading in the case where
HDM operation is already found to be active, so just call it @retval.

36bfc6ad50 cxl/pci: Make cxl_dvsec_ranges() failure not fatal to cxl_pci
cxl_dvsec_ranges(), the helper for enumerating the presence of an active
legacy CXL.mem configuration on a CXL 2.0 Memory Expander, is not fatal
for cxl_pci because there is still value to enable mailbox operations
even if CXL.mem operation is disabled. Recall that the reason cxl_pci
does this initialization and not cxl_mem is to preserve the useful
property (for unit testing) that cxl_mem is cxl_memdev + mmio generic,
and does not require access to a 'struct pci_dev' to issue config
cycles.

Update 'struct cxl_endpoint_dvsec_info' to carry either a positive
number of non-zero size legacy CXL DVSEC ranges, or the negative error
code from __cxl_dvsec_ranges() in its @ranges member.

e08063fb87 cxl/mem: Drop DVSEC vs EFI Memory Map sanity check
When the driver finds legacy DVSEC ranges active on a CXL Memory
Expander it indicates that platform firmware is not aware of, or is
deliberately disabling common CXL 2.0 operation. In this case Linux
generally has no choice, but to leave the device alone.

The driver attempts to validate that the DVSEC range is in the EFI
memory map. Remove that logic since there is no requirement that the
BIOS publish DVSEC ranges in the EFI Memory Map.

In the future the driver will want to permanently reserve this capacity
out of the available CFMWS capacity and hide it from
request_free_mem_region(), but it serves no purpose to warn about the
range not appearing in the EFI Memory Map.

932aba1e16 stat: fix inconsistency between struct stat and struct compat_stat
struct stat (defined in arch/x86/include/uapi/asm/stat.h) has 32-bit
st_dev and st_rdev; struct compat_stat (defined in
arch/x86/include/asm/compat.h) has 16-bit st_dev and st_rdev followed by
a 16-bit padding.

This patch fixes struct compat_stat to match struct stat.

[ Historical note: the old x86 'struct stat' did have that 16-bit field
  that the compat layer had kept around, but it was changes back in 2003
  by "struct stat - support larger dev_t":

    https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=e95b2065677fe32512a597a79db94b77b90c968d

  and back in those days, the x86_64 port was still new, and separate
  from the i386 code, and had already picked up the old version with a
  16-bit st_dev field ]

Note that we can't change compat_dev_t because it is used by
compat_loop_info.

Also, if the st_dev and st_rdev values are 32-bit, we don't have to use
old_valid_dev to test if the value fits into them.  This fixes
-EOVERFLOW on filesystems that are on NVMe because NVMe uses the major
number 259.

73f62e60d8 lkdtm: Move crashtype definitions into each category
It's long been annoying that to add a new LKDTM test one had to update
lkdtm.h and core.c to get it "registered". Switch to a per-category
list and update the crashtype walking code in core.c to handle it.

This also means that all the lkdtm_* tests themselves can be static now.
