-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Since kernel 4.17-rc1, sys_* syscalls can no longer be called directly:
-819671ff849b ("syscalls: define and explain goal to not call syscalls in the kernel")
-
-Since cryptodev uses sys_close() - and this has been removed in commit:
-2ca2a09d6215 ("fs: add ksys_close() wrapper; remove in-kernel calls to sys_close()")
-cryptodev has to be updated to use the ksys_close() wrapper.

-Subject: [PATCH 3/3] convert to new AEAD interface in kernels v4.2+
-
-The crypto API for AEAD ciphers changed in recent kernels so that
-associated data is now part of both source and destination scatter
-gathers. The source, destination and associated data buffers need
-to be stiched accordingly for the operations to succeed:
-
-src_sg: auth_buf + src_buf
-dst_sg: auth_buf + (dst_buf + tag space)
-
-This patch fixes a kernel crash observed with cipher-gcm test.
-
-See also kernel patch: 81c4c35eb61a69c229871c490b011c1171511d5a

-
-In response to a change in binutils, commit b21ebf2fb4c
-(x86: Treat R_X86_64_PLT32 as R_X86_64_PC32) was applied to
-the linux kernel during the 4.16 development cycle and has
-since been backported to earlier stable kernel series. The
-change results in the failure message in $SUBJECT when
-rebooting via kexec.
-
-Fix this by replicating the change in kexec.

+Subject: [PATCH 1/3] kbuild: install_headers.sh: Strip _UAPI from
+ #if-defined() guards
+
+install_headers.sh knows how to strip the _UAPI prefix from #ifdef/
+ifndef and #define directives used to guard headers against multiple
+or inappropriate inclusion.  Currently this does not work for guards
+in the "#if defined()" style, which may be needed for non-trivial
+cases.
+
+This patch adds similar logic so that the _UAPI prefix is also
+stripped from guard directives written using "#if defined()" etc.
+
+This is not completely foolproof, but will work for simple cases of
+using #if defined() to guard against inappropriate header inclusion.

+Date: Wed, 21 Nov 2018 15:12:43 +0800
+Subject: [PATCH] scripts: Use fixed input and output files instead of pipe for here-doc
+
+There was a bug of "as" in binutils that when it checks if the input file and
+output file are the same one, it would not check if they are on the same block
+device. The check is introduced by the following commit in v2.31.
+
+https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=
+67f846b59b32f3d704c601669409c2584383fea9
+
+The here-doc usage in this script creates temporary file in /tmp. When we run in
+an environment where /tmp has rarely been used, the newly created temporary file
+may have a very low inode number. If the inode number was 6 which is the same as
+/dev/null, the as would wrongly think the input file and the output file are the
+same and report the following error.
+
+*** Compiler lacks asm-goto support.. Stop.
+
+One observed case happened in docker where the /tmp could be so rarely used that
+very low number inode may be allocated and triggers the error.
+
+The fix below for the bug only exists on the master branch of binutils so far
+and has not been released from upstream. As the convict is introduced since
+v2.31, only v2.31 is affected.
+
+https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=
+2a50366ded329bfb39d387253450c9d5302c3503
+
+When building linux-libc-headers we need to use "as" in binutils which does not
+contain the fix for the moment. To work around the error, we create a fixed
+temporary file to contain the program being tested.
+
+This patch also removes ">/dev/null 2>&1" so we will have more direct error
+information in case something else wrong happened.
+
+Upstream-Status: Inappropriate [A work around for binutils v2.31]

-
-    fs_info can be extracted from btrfs_block_group_cache, and all
-    btrfs_block_group_cache is created by btrfs_create_block_group_cache()
-    with fs_info initialized, no need to worry about NULL pointer

+Subject: [PATCH 1/9] Fix: signal: Distinguish between kernel_siginfo and
+ siginfo (v4.20)
+
+See upstream commit :
+
+  commit ae7795bc6187a15ec51cf258abae656a625f9980
+  Author: Eric W. Biederman <ebiederm@xmission.com>
+  Date:   Tue Sep 25 11:27:20 2018 +0200
+
+    signal: Distinguish between kernel_siginfo and siginfo
+
+    Linus recently observed that if we did not worry about the padding
+    member in struct siginfo it is only about 48 bytes, and 48 bytes is
+    much nicer than 128 bytes for allocating on the stack and copying
+    around in the kernel.
+
+    The obvious thing of only adding the padding when userspace is
+    including siginfo.h won't work as there are sigframe definitions in
+    the kernel that embed struct siginfo.
+
+    So split siginfo in two; kernel_siginfo and siginfo.  Keeping the
+    traditional name for the userspace definition.  While the version that
+    is used internally to the kernel and ultimately will not be padded to
+    128 bytes is called kernel_siginfo.
+
+    The definition of struct kernel_siginfo I have put in include/signal_types.h
+
+    A set of buildtime checks has been added to verify the two structures have
+    the same field offsets.
+
+    To make it easy to verify the change kernel_siginfo retains the same
+    size as siginfo.  The reduction in size comes in a following change.

+
+    signal: Remove SEND_SIG_FORCED
+
+    There are no more users of SEND_SIG_FORCED so it may be safely removed.
+
+    Remove the definition of SEND_SIG_FORCED, it's use in is_si_special,
+    it's use in TP_STORE_SIGINFO, and it's use in __send_signal as without
+    any users the uses of SEND_SIG_FORCED are now unncessary.
+
+    This makes the code simpler, easier to understand and use.  Users of
+    signal sending functions now no longer need to ask themselves do I
+    need to use SEND_SIG_FORCED.

+Subject: [PATCH 3/9] Fix: ext4: adjust reserved cluster count when removing
+ extents (v4.20)
+
+See upstream commit :
+
+  commit 9fe671496b6c286f9033aedfc1718d67721da0ae
+  Author: Eric Whitney <enwlinux@gmail.com>
+  Date:   Mon Oct 1 14:25:08 2018 -0400
+
+    ext4: adjust reserved cluster count when removing extents
+
+    Modify ext4_ext_remove_space() and the code it calls to correct the
+    reserved cluster count for pending reservations (delayed allocated
+    clusters shared with allocated blocks) when a block range is removed
+    from the extent tree.  Pending reservations may be found for the clusters
+    at the ends of written or unwritten extents when a block range is removed.
+    If a physical cluster at the end of an extent is freed, it's necessary
+    to increment the reserved cluster count to maintain correct accounting
+    if the corresponding logical cluster is shared with at least one
+    delayed and unwritten extent as found in the extents status tree.
+
+    Add a new function, ext4_rereserve_cluster(), to reapply a reservation
+    on a delayed allocated cluster sharing blocks with a freed allocated
+    cluster.  To avoid ENOSPC on reservation, a flag is applied to
+    ext4_free_blocks() to briefly defer updating the freeclusters counter
+    when an allocated cluster is freed.  This prevents another thread
+    from allocating the freed block before the reservation can be reapplied.
+
+    Redefine the partial cluster object as a struct to carry more state
+    information and to clarify the code using it.
+
+    Adjust the conditional code structure in ext4_ext_remove_space to
+    reduce the indentation level in the main body of the code to improve
+    readability.

+Subject: [PATCH 5/9] Fix: Remove 'type' argument from access_ok() function
+ (v5.0)
+
+See upstream commit :
+
+  commit 96d4f267e40f9509e8a66e2b39e8b95655617693
+  Author: Linus Torvalds <torvalds@linux-foundation.org>
+  Date:   Thu Jan 3 18:57:57 2019 -0800
+
+    Remove 'type' argument from access_ok() function
+
+    Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
+    of the user address range verification function since we got rid of the
+    old racy i386-only code to walk page tables by hand.
+
+    It existed because the original 80386 would not honor the write protect
+    bit when in kernel mode, so you had to do COW by hand before doing any
+    user access.  But we haven't supported that in a long time, and these
+    days the 'type' argument is a purely historical artifact.
+
+    A discussion about extending 'user_access_begin()' to do the range
+    checking resulted this patch, because there is no way we're going to
+    move the old VERIFY_xyz interface to that model.  And it's best done at
+    the end of the merge window when I've done most of my merges, so let's
+    just get this done once and for all.
+
+    This patch was mostly done with a sed-script, with manual fix-ups for
+    the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
+
+    There were a couple of notable cases:
+
+     - csky still had the old "verify_area()" name as an alias.
+
+     - the iter_iov code had magical hardcoded knowledge of the actual
+       values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
+       really used it)
+
+     - microblaze used the type argument for a debug printout
+
+    but other than those oddities this should be a total no-op patch.
+
+    I tried to fix up all architectures, did fairly extensive grepping for
+    access_ok() uses, and the changes are trivial, but I may have missed
+    something.  Any missed conversion should be trivially fixable, though.

+
+    btrfs: Remove fsid/metadata_fsid fields from btrfs_info
+
+    Currently btrfs_fs_info structure contains a copy of the
+    fsid/metadata_uuid fields. Same values are also contained in the
+    btrfs_fs_devices structure which fs_info has a reference to. Let's
+    reduce duplication by removing the fields from fs_info and always refer
+    to the ones in fs_devices. No functional changes.

-Subject: [PATCH] Allow multiple attempts to connect to relayd.
-
-It is unclear why a session needs to be made
-unusable after a failure to connect to relayd
-since a check for a relayd connection is
-always made before a session can be configured.

+Subject: [PATCH lttng-tools 2/2] Fix: test: unit: the tree origin can be a
+ symlink itself
+
+Problem:
+
+The base tree is defined as "/tmp/.....XXXXXX".
+On systems where "/tmp/" is itself a symlink utils_expand_path will
+expand the tree origin itself.
+
+For example on a base core-image-minimal Yocto build /tmp is a symlink
+to "/var/tmp", which is a symlink to "/var/volatile".
+
+utils_expand_path will return something like this for the symlink test:
+"/var/volative/.....XXXXXX/...." which is the valid result.
+
+Solution:
+
+Simply use realpath on the tree_origin and use this path to perform the
+test validation.
+
+This work was performed in the effort to support yocto fully and be able
+to run the test suite to detect problem as early as possible.

+Subject: [PATCH lttng-tools] Skip when testapp is not present
+
+We expect lttng-ust do be present, this is a wrong assumptions.
+
+This is a quick fix. The real fix is to either detect at runtime
+lttng-ust support or at build time (HAVE_LIBLTTNG_UST_CTL).
+
+This prevent hang for make check done on a build configured with
+--without-lttng-ust.
+
+Upstream-Status: Inappropriate [other] 
+Reason: This patch is inappropriate for upstream for 2.10 stable release 
+since we do not backport "superficial" fix to the test suite. We do 
+backport when a test is broken. The fact that on --without-lttng-ust 
+hang is not a "broken" test per-see. Still, a variation of this fix will 
+be upstreamed in our master branch and possibly 2.11. The upstreamed 
+version will split the test in kernel/ust test and skip them at the 
+build system level. This patch is more succinct.

+
+The problem was easily reproducible (~6 crash on ~300 runs). A prototype fix
+using mutex around the getgrnam yielded no crash in over 1000 runs. This
+patch yielded the same results as the prototype fix.
+
+Unfortunately we cannot rely on a mutex in liblttng-ctl since we cannot
+enforce the locking for the application using the lib.
+
+Use getgrnam_r instead.
+
+The previous implementation of utils_get_group_id returned the gid of
+the root group (0) on error/not found. lttng_check_tracing_group needs
+to know if an error/not found occured, returning the root group is not
+enough. We now return the gid via the passed parameter. The caller is
+responsible for either defaulting to the root group or propagating the
+error.
+
+We also do not want to warn when used in liblttng-ctl context. We might
+want to move the warning elsewhere in the future. For now, pass a bool
+if we need to warn or not.

+
+On MUSL libc the _SC_NPROCESSORS_CONF sysconf will report the number of
+CPUs allocated to the task based on the affinity mask instead of the
+total number of CPUs configured on the system.
