-From 0f9ee000904ffd1e171ba1f000a83e5ce3717e45 Mon Sep 17 00:00:00 2001
-From: David Hildenbrand <david@redhat.com>
-Date: Thu, 22 Nov 2018 11:09:38 +0100
-Subject: [PATCH] [PATCH] exclude pages that are logically offline
-
-Linux marks pages that are logically offline via a page flag (map count).
-Such pages e.g. include pages infated as part of a balloon driver or
-pages that were not actually onlined when onlining the whole section.
-
-While the hypervisor usually allows to read such inflated memory, we
-basically read and dump data that is completely irrelevant. Also, this
-might result in quite some overhead in the hypervisor. In addition,
-we saw some problems under Hyper-V, whereby we can crash the kernel by
-dumping, when reading memory of a partially onlined memory segment
-(for memory added by the Hyper-V balloon driver).
-
-Therefore, don't read and dump pages that are marked as being logically
-offline.

-Subject: [PATCH] [PATCH v2] honor the CFLAGS from environment variables
-
-This makes it possible to pass in extra cflags, for example, hardening
-flags could be passed in with environment variable when building a
-hardened package.
-
-Also introduce a CFLAGS_BASE to hold common CFLAGS, which simplify the
-CFLAGS definition.

-Subject: [PATCH] [PATCH] x86_64: Add support for AMD Secure Memory Encryption
-
-On AMD machine with Secure Memory Encryption (SME) feature, if SME is
-enabled, page tables contain a specific attribute bit (C-bit) in their
-entries to indicate whether a page is encrypted or unencrypted.
-
-So get NUMBER(sme_mask) from vmcoreinfo, which stores the value of
-the C-bit position, and drop it to obtain the true physical address.

-Subject: [PATCH] x86: Introduce a new option --reuse-video-type
-
-After commit 060eee58 "x86: use old screen_info if needed", kexec-tools
-will force use old screen_info and vga type if failed to determine
-current vga type. But it is not always a good idea.
-
-Currently kernel hanging is inspected on some hyper-v VMs after this
-commit, because hyperv_fb will mimic EFI (or VESA) VGA on first boot
-up, but after the real driver is loaded, it will switch to new mode
-and no longer compatible with EFI/VESA VGA. Keep setting
-orig_video_isVGA to EFI/VESA VGA flag will get wrong driver loaded and
-try to manipulate the framebuffer in a wrong way.
-
-We can't ensure this won't happen on other framebuffer drivers, But
-it's a helpful feature if the framebuffer drivers just work. So this
-patch introduce a --reuse-video-type options to let user decide if the
-old screen_info hould be used unconditional or not.

+
+Some code related to vmcore-dmesg.c is put into the util_lib, which
+is not very reasonable, so lets move it back and tidy up those code.
+
+In addition, that will also help to limit the size of vmcore-dmesg.txt
+in vmcore-dmesg.c instead of elf_info.c.

+Subject: [PATCH 4/5] Limit the size of vmcore-dmesg.txt to 2G
+
+With some corrupted vmcore files, the vmcore-dmesg.txt file may grow
+forever till the kdump disk becomes full, and also probably causes
+the disk error messages as follow:
+...
+sd 0:0:0:0: [sda] tag#6 FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
+sd 0:0:0:0: [sda] tag#6 CDB: Read(10) 28 00 08 06 4c 98 00 00 08 00
+blk_update_request: I/O error, dev sda, sector 134630552
+sd 0:0:0:0: [sda] tag#7 FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
+sd 0:0:0:0: [sda] tag#7 CDB: Read(10) 28 00 08 06 4c 98 00 00 08 00
+blk_update_request: I/O error, dev sda, sector 134630552
+...
+
+If vmcore-dmesg.txt occupies the whole disk, the vmcore can not be
+saved, this is also a problem.
+
+Lets limit the size of vmcore-dmesg.txt to avoid such problems.

+Subject: [PATCH] [PATCH] Fix off-by-one issue in exclude_nodata_pages()
+
+When building a dump bitmap (2nd bitmap) for the ELF dump, the last pfn
+of the cycle is always ignored in exclude_nodata_pages() function due to
+off-by-one error on cycle boundary check. Thus, the respective bit of
+the bitmap is never cleared.
+
+That can lead to the error when such a pfn should not be dumpable (e.g.
+the last pfn of the ELF-load of zero filesize). Based on the bit in the
+bitmap the page is treated as dumpable in write_elf_pages_cyclic() function
+and the follow on error is triggered in write_elf_load_segment() function
+due to the failing sanity check of paddr_to_offset2():
+
+   $ makedumpfile -E dump.elf dump.elf.E
+   Checking for memory holes                         : [100.0 %] |

+kernel commit 326e1b8f83a4 ("mm/sparsemem: introduce a SECTION_IS_EARLY

+makedumpfile an error like the following:

+  create_2nd_bitmap: Can't exclude unnecessary pages.
+
+To fix this, SECTION_MAP_LAST_BIT needs to be updated. The bit has not
+been used until the addition, so we can just increase the value.

+Subject: [PATCH] [PATCH] assign bitmap1/2 fd for subprocess in non-cyclic mode
+
+In non-cyclic mode with the --split option, each subprocess inherits
+bitmap1/2->fd from parent.  Then they lseek()/read() on the same fd,
+which means that they interfere with each other.
+
+This breaks the purpose of SPLITTING_FD_BITMAP(i) for each subprocess.
+Without this patch, makedumpfile can fail with error like the following
+in refiltering, or can break the dumpfile silently by excluding pages
+wrongly.
+
+  readpage_kdump_compressed: pfn(2fc1000) is excluded from vmcore.
+  readmem: type_addr: 1, addr:2fc1000000, size:4096
+  read_pfn: Can't get the page data.
+
+Fix it by assigning a subprocess dedicated fd to bitmap1/2->fd.
