 Subject: [PATCH 1/9] Adding the zram decompression algorithm "lzo-rle"
 Port the improved decompression method for "lzo" in the kernel to
 support decompression of "lzorle".
 Since Linux 5.1, the default compression algorithm for zram was changed
 from "lzo" to "lzo-rle".  The crash-utility only supports decompression
 for "lzo", when parsing vmcore files that utilize zram compression, such
 as when using the gcore command to detach process core dump files,
 parsing cannot be completed successfully.
 before:
        crash> gcore -v 0 1

 Subject: [PATCH 1/2] Fix "kmem -i" and "swap" commands on Linux 6.10-rc1 and
 later kernels
 Kernel commit 798cb7f9aec3 ("swapon(2)/swapoff(2): don't bother with
 block size") removed swap_info_struct.old_block_size member at Linux
 6.10-rc1.  The crash-utility has used this to determine whether a swap
 is a partition or file and to determine the way to get the swap path.
 Withtout the patch, the "kmem -i" and "swap" commands fail with the
 following error messsage:
  crash> kmem -i
  ...
     TOTAL HUGE  13179392      50.3 GB         ----
      HUGE FREE  13179392      50.3 GB  100% of TOTAL HUGE
  swap: invalid (optional) structure member offsets: swap_info_struct_swap_device or swap_info_struct_old_block_size
        FILE: memory.c  LINE: 16032  FUNCTION: dump_swap_info()
 The swap_file member of recent swap_info_struct is a pointer to a
 struct file (once upon a time it was dentry), use this fact directly.

 Subject: [PATCH 1/5] arm64: fix a potential segfault when unwind frame
 The range of frame->fp is checked insufficiently, which may lead to a wrong
 next fp. As a result, bt->stackbuf will be accessed out of range, and segfault.

 Subject: [PATCH 2/9] Cleanup: replace struct zspage_5_17 with union
 This patch is a refactoring on commit [1], and has no functional
 change. The reason is that the structure of zspage has not changed,
 just new bits have been introduced. So a union is better to reduce
 code replication.

 Subject: [PATCH 2/2] List: enable LIST_HEAD_FORMAT for -r option
 Currently, the LIST_HEAD_FORMAT is not set, 'list -r' will list the
 traversal results in order, not in the reverse order. This is not
 the expected behavior.
 Let's enable the LIST_HEAD_FORMAT for -r option by default.

 Subject: [PATCH 4/5] LoongArch64: fix incorrect code in the main()
 The commit c3939d2e1930 contains incorrect code that starts with "+",
 for example:

 +        !machine_type("S390X") && !machine_type("RISCV64") &&
 ++       !machine_type("LOONGARCH64"))
 See the main() in the main.c
 ...
         } else if (STREQ(long_options[option_index].name, "kaslr")) {
             if (!machine_type("X86_64") &&

 +                !machine_type("LOONGARCH64"))
 Let's remove it from the main().

 Kernel commit 8f69cba096b5 ("x86: Rename __{start,end}_init_task to

 Subject: [PATCH 5/5] Fix "irq -a" exceeding the memory range issue
 Previously without the patch, there was an error observed as follows:
  crash> irq -a
  IRQ NAME                 AFFINITY
    0 timer                0-191

   84 smartpqi             72-73,168
  irq: page excluded: kernel virtual address: ffff97d03ffff000  type: "irq_desc affinity"
 The reason is the reading of irq affinity exceeded the memory range, see
 the following debug info:
  Thread 1 "crash" hit Breakpoint 1, generic_get_irq_affinity (irq=85) at kernel.c:7373
  7375		irq_desc_addr = get_irq_desc_addr(irq);
  (gdb) p/x irq_desc_addr
  $1 = 0xffff97d03f21e800
  crash> struct irq_desc 0xffff97d03f21e800
  struct irq_desc {
    irq_common_data = {
      state_use_accessors = 425755136,
      node = 3,
      handler_data = 0x0,
      msi_desc = 0xffff97ca51b83480,
      affinity = 0xffff97d03fffee60,
      effective_affinity = 0xffff97d03fffe6c0
    },
  crash> whatis cpumask_t
  typedef struct cpumask {
      unsigned long bits[128];
  } cpumask_t;
  SIZE: 1024
 In order to get the affinity, crash will read the memory range 0xffff97d03fffee60
 ~ 0xffff97d03fffee60 + 1024(0x400) by line:
 	readmem(affinity_ptr, KVADDR, affinity, len,
 	        "irq_desc affinity", FAULT_ON_ERROR);
 However the reading will exceed the effective memory range:

 The beginning physical address, aka 0x83fffe000, is located in the usable
 area and is readable, however the later physical address, starting from
 0x83ffff000, is located in reserved region and not readable. In fact,
 the affinity member is allocated by alloc_cpumask_var_node(), for the 192 CPUs
 system, the allocated size is only 24, and we can see it is within
 the kmalloc-32 slab. So it is incorrect to read 1024 length(given by
 STRUCT_SIZE("cpumask_t")), only 24 is enough.
 Since there are plenty of places in crash which takes the value of
 STRUCT_SIZE("cpumask_t"), and works fine for the past, this patch will
 not modify them all, only the one which encountered this issue(hunk in
 kernel.c), and the one with the same DIV_ROUND_UP() (hunk in tools.c).

 Subject: [PATCH 5/9] x86_64: fix for adding top_of_kernel_stack_padding for
 kernel stack
 With Kernel commit 65c9cc9e2c14 ("x86/fred: Reserve space for the FRED
 stack frame") in Linux 6.9-rc1 and later, x86_64 will add extra padding
 ('TOP_OF_KERNEL_STACK_PADDING (2 * 8)', see: arch/x86/include/asm\
 /thread_info.h,) for kernel stack when the CONFIG_X86_FRED is enabled.
 As a result, the pt_regs will be moved downwards due to the offset of
 padding, and the values of registers read from pt_regs will be incorrect
 as below.

 Subject: [PATCH 7/9] X86 64: fix for crash session loading failure
 Kernel commit 223b5e57d0d5 ("mm/execmem, arch: convert remaining
 overrides of module_alloc to execmem") makes crash session loading
 failure as below:
  # ./crash -s
  crash: seek error: kernel virtual address: ffffffff826bb418  type: "page_offset_base"
 For X86 64 architecture, currently crash will search for symbol
 "module_load_offset" to determine if the KASLR is enabled, and go
 into the relevant code block. But the symbols "module_load_offset"
 has been removed since Linux v6.10-rc1, which caused the current
 failure.
 And this issue can occur with live debugging and core dump file
 debugging.
 Let's check the symbol "kaslr_regions" instead of "module_load_offset"
 to fix it.

 Subject: [PATCH 02/14] Fix typos in offset_table and missing "help -o" items
 A few of zram related members in the offset_table have typos and
 irregular naming rule, also they are not present in the "help -o"
 output.  Let's fix these.

 Subject: [PATCH 03/14] zram: Fixes for lookup_swap_cache()
 Fix the following three issues:
 (1) swap cache missing page tree offset
    The radix or xarray start at an offset inside struct address_space.
 (2) swap cache entries are pointer to struct page
    The entries in radix, xarray (swap cache) are address to struct page.
 (3) exclude shadow entries from swap cache lookup
    radix or xarray can contain shadow entries from previous page
    entries. These should be ignored when looking for a page pointer.
 Without the patch,
 - lookup_swap_cache() returns NULL since do_xarray() call returns FALSE,
 - in try_zram_decompress(), since 'entry' is NULL, page is filled with 0,
    if (!entry || (flags & ZRAM_FLAG_SAME_BIT)) {
 and pages in swap cache will be seen to be a 'zero' page.

 There is an issue that, for kernel modules, "dis -rl" fails to display

 The root cause is, after kernel module been loaded by mod command, the symtable
 is not expanded in gdb side. crash bt or dis command will trigger such an
 expansion. However the symtable expansion is different for the 2 commands:

 For the stacktrace of "dis -rl", it calls dw2_expand_all_symtabs() to expand
 all symtable of the objfile, or "*.ko.debug" in our case. However for
 the stacktrace of "bt", it doesn't expand all, but only a subset of symtable
 which is enough to find a symbol by dw2_lookup_symbol(). As a result, the
 objfile->compunit_symtabs, which is the head of a single linked list of
 struct compunit_symtab, is not NULL but didn't contain all symtables. It
 will not be reinitialized in gdb_get_line_number() by "dis -rl" because
 !objfile_has_full_symbols(objfile) check will fail, so it cannot display
 the proper code line number data.
 Since objfile_has_full_symbols(objfile) check cannot ensure all symbols
 been expanded, this patch add a new member as a flag for struct objfile
 to record if all symbols have been expanded. The flag will be set only ofter
 expand_all_symtabs been called.

 Subject: [PATCH 05/14] symbols: skip load .init.* sections if module was
 successfully initialized
 There might be address overlap of one modules .init.text symbols and
 another modules .text symbols. As a result, gdb fails to translate the
 address to symbol name correctly:
  crash> sym -m virtio_blk | grep MODULE
  ffffffffc00a4000 MODULE START: virtio_blk
  ffffffffc00a86ec MODULE END: virtio_blk
  crash> gdb info address floppy_module_init
  Symbol "floppy_module_init" is a function at address 0xffffffffc00a4131.
 Since the .init.* sections of a module had been freed by kernel if the
 module was initialized successfully, there is no need to load the .init.*
 sections data from "*.ko.debug" in gdb to create such an overlap.
 lm->mod_init_module_ptr is used as a flag of whether module is freed.
 Without the patch:
  crash> mod -S
  crash> struct blk_mq_ops 0xffffffffc00a7160
  struct blk_mq_ops {
    queue_rq = 0xffffffffc00a45b0 <floppy_module_init+1151>, <-- translated from module floppy
    map_queue = 0xffffffff813015c0 <blk_mq_map_queue>,
    ...snip...
    complete = 0xffffffffc00a4370 <floppy_module_init+575>,
    init_request = 0xffffffffc00a4260 <floppy_module_init+303>,
    ...snip...
  }
 With the patch:
  crash> mod -S
  crash> struct blk_mq_ops 0xffffffffc00a7160
  struct blk_mq_ops {
    queue_rq = 0xffffffffc00a45b0 <virtio_queue_rq>, <-- translated from module virtio_blk
    map_queue = 0xffffffff813015c0 <blk_mq_map_queue>,

    complete = 0xffffffffc00a4370 <virtblk_request_done>,

 Subject: [PATCH 06/14] use NR_SWAPCACHE when nr_swapper_spaces isn't available
 In 5.12 the following change was introduced:
 b6038942480e ("mm: memcg: add swapcache stat for memcg v2")
 Then the variable 'nr_swapper_spaces' is not read (unless
 CONFIG_DEBUG_VM=y).  In GKI builds this variable is then optimized
 out. But the same change provided a new way to obtain the same
 information, using NR_SWAPCACHE.

 Subject: [PATCH 11/14] RISCV64: Fix 'bt' output when no ra on the stack top
 Same as the Linux commit f766f77a74f5 ("riscv/stacktrace: Fix
 stack output without ra on the stack top").
 When a function doesn't have a callee, then it will not
 push ra into the stack, such as lkdtm functions, so
 correct the FP of the second frame and use pt_regs to get
 the right PC of the second frame.
 Before this patch, the `bt -f` outputs only the first frame with
 the wrong PC and FP of next frame:
 ```

 arm64_get_vmcoreinfo
 Rewrite the arm64_get_vmcoreinfo_ul to arm64_get_vmcoreinfo,
 add a new parameter "base" for it.
 Also use it to simplify the arm64 code.

 Subject: [PATCH 13/14] help.c: Remove "kmem -l" help messages
 "kmem -l" option has existed when crash git project initialization, but
 its help message was not accurate (extra arguments a|i|ic|id was missing).
 In addition, those symbols required by the -l option were for very old
 kernels, at least 2.6 kernels don't contain them.  Also, this option has
 not been fixed for a long time.
 Instead of document this option, hide it from help messages.

 accessed out of range, and segfault.
