+Subject: [PATCH] cmcurl: link librt
+
+When cmake is linked against LibreSSL, there might be an indirect
+dependency on librt on certain systems if LibreSSL's libcrypto uses
+clock_gettime() from librt:
+
+    [ 28%] Linking C executable LIBCURL
+    .../lib/libcrypto.a(getentropy_linux.o): In function `getentropy_fallback':
+    getentropy_linux.c:(.text+0x16d): undefined reference to `clock_gettime'
+    getentropy_linux.c:(.text+0x412): undefined reference to `clock_gettime'
+    collect2: error: ld returned 1 exit status
+    make[5]: *** [Utilities/cmcurl/LIBCURL] Error 1
+
+Modify the cmcurl CMakeLists.txt to check for clock_gettime() in librt
+and unconditionally link the rt library when the symbol is found.

+This package had an absolute path for sys/types.h, which doesn't

+This patch makes the types a relative path, and allows the system

+Date: Mon, 4 Sep 2017 10:47:33 +0800
+Subject: [PATCH] build: AC_USE_SYSTEM_EXTENSIONS in configure.ac.
+
+This would, e.g. define _GNU_SOURCE in config.h, enabling the
+reallocarray() prototype in glibc 2.26+ on Linux systems with that
+version of glibc.
+
+Fixes #241.

+Subject: [PATCH] gm_utils.cpp: Call clear instead of empty.
+
+Since the intention seem to be to erase the next word, I believe calling empty
+was a mistake and it should have been clear.  Empty does nothing in this
+context.
+
+* src/gm_utils.cpp (wrap_cstr): Call clear.

+Subject: openwrt: remove trailing slash in install destdir
+
+A command like /bin/sh ../../i586-poky-linux-libtool   --mode=install /usr/bin/install -c   gck-roots-store-standalone.la '/media/data1/builds/poky1/tmp/work/core2-poky-linux/gnome-keyring-2.26.1-r1/image/usr/lib/gnome-keyring/standalone/' fails (e.g. gnome-keyring or pulseaudio)
+
+This is because libdir has a trailing slash which breaks the comparision.

+dnl This test is for network applications that need socket() and
+dnl gethostbyname() -ish functions.  Under Solaris, those applications
+dnl need to link with "-lsocket -lnsl".  Under IRIX, they need to link
+dnl with "-lnsl" but should *not* link with "-lsocket" because
+dnl libsocket.a breaks a number of things (for instance:
+dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
+dnl versions of IRIX).
+dnl
+dnl Unfortunately, many application developers are not aware of this,
+dnl and mistakenly write tests that cause -lsocket to be used under
+dnl IRIX.  It is also easy to write tests that cause -lnsl to be used
+dnl under operating systems where neither are necessary (or useful),
+dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
+dnl
+dnl This test exists so that every application developer does not test
+dnl this in a different, and subtly broken fashion.
+
+dnl It has been argued that this test should be broken up into two
+dnl seperate tests, one for the resolver libraries, and one for the
+dnl libraries necessary for using Sockets API. Unfortunately, the two
+dnl are carefully intertwined and allowing the autoconf user to use
+dnl them independantly potentially results in unfortunate ordering
+dnl dependancies -- as such, such component macros would have to
+dnl carefully use indirection and be aware if the other components were
+dnl executed. Since other autoconf macros do not go to this trouble,
+dnl and almost no applications use sockets without the resolver, this
+dnl complexity has not been implemented.
+dnl
+dnl The check for libresolv is in case you are attempting to link
+dnl statically and happen to have a libresolv.a lying around (and no
+dnl libnsl.a).

+Date: Sun, 26 Apr 2020 17:15:17 +0200
+Subject: [PATCH 1/2] Add compatibility with non Linux hosts
+
+This adds some changes to the u-boot tools to make it possible to build
+them on non Linux hosts like MacOS or FreeBSD.
+
+asm/byteorder.h, asm/posix_types.h, asm/types.h and linux/kernel.h are
+not available on such systems. Remove the include and add the necessary
+parts for these header files manually or remove the usage too.
+
+__u64 is not available on FreeBSD, remove its usage.

+Subject: [PATCH] configure.py: Support --gtest-source-dir to build tests.
+
+Allow the Ninja build plan generated by configure.py to
+build `ninja_test` by compiling GoogleTest from source if
+the path to the library if passed through the new option
+`--gtest-source-dir` or the GTEST_SOURCE_DIR environment
+variable.
+
+For simplicity, probing for an installed version of the
+library, and linking to it, is not supported (use the
+CMake build for this).
+
+This also removes the obsolete `--gtest-dir` option.
+
++ Update README.md

+* tests/ed-style: New test case.
+* tests/Makefile.am (TESTS): Add test case.

+Subject: [PATCH] Fix error handling with git-style patches
+
+When an error is encountered in output_files(), the subsequent call to
+cleanup() calls back into output_files() resulting in an infinte recursion.
+This is trivially reproduced with a git-style patch (which utilizes
+output_file_later()) that tries to patch a nonexistent or unreadable
+file (see attached test case).
+
+* src/patch.c: (output_files) clear the files_to_output list before
+iterating it, so that recursive calls won't iterate the same files.

+Subject: [PATCH] sed: fix symlink bufsize readlink check
+
+Problem reported by Hauke Mehrtens.
+* sed/utils.c (follow_symlink): Fix typo when checking size of
+second and later symlink, when that symlink is so large that it
+does not fit into the buffer.  Although the bug is not a buffer
+overflow, it does cause sed to mishandle the symlink.
+* testsuite/follow-symlinks.sh: Test for the bug.

+Subject: [PATCH] xz_wrapper: support multiple lzma configuration options
+
+Add option to configure preset, lc, lp and pb lzma parameters.
+-Xpreset can be used to set the compression level.
+-Xe can be used to set the 'EXTREME' flag to use the lzma compression
+options tweaking additional settings on top of the compression level set.
+
+New option added:
+ -Xpreset
+ -Xe
+ -Xlc
+ -Xlp
+ -Xpb

+
+https://github.com/plougher/squashfs-tools/pull/218#issuecomment-1515197256
+
+The new options can be enabled by editing the Makefile or by defining

+
+* src/Makefile.am (tar_LDADD): Add libiconv libraries.
+
+Adapted upstream commit 8632df398b2f548465ebe68b8f494c0d6f8d913d to patch
+the pregenerated Makefile.in instead of Makefile.am to avoid invoking
+automake which requires m4.
+
+This is required for macOS, as otherwise it will fail with:
+Undefined symbols for architecture arm64:
+  "_iconv", referenced from:
+      _utf8_convert in utf8.o
+  "_iconv_open", referenced from:

+Infozip's LFS check can't work for cross-compilation

+Instead, use to LFS test used by autotools which is a

+to allow for reproducible builds of .zip files
+
+See https://reproducible-builds.org/ for why this is good
+and https://reproducible-builds.org/specs/source-date-epoch/
+for the definition of this variable.
+
+Uses clamping to keep older mtimes than SOURCE_DATE_EPOCH intact.

+Subject: [PATCH] make encrypted archives reproducible
+
+Zip always try to generate new encryption header depending on execution
+time and process id, which is far from being reproducible. This commit
+changes the zip srand() seed to a predictable value to generate
+reproducible random bytes for the encryption header. This will compromise
+the goal of secure archive encryption, but it would not be a big problem
+for our purpose.

+Subject: [PATCH] Provide variant pkg-config file for multi-threaded static lib
+
+Multi-threaded static library require -pthread to correctly link and works.
+The pkg-config we provide tho only works with dynamic multi-threaded library
+and won't provide the correct libs and cflags values if lib-mt is used.
+
+To handle this, introduce an env variable MT to permit advanced user to
+install and generate a correct pkg-config file for lib-mt or detect if
+lib-mt target is called.
+
+With MT env set on calling make install-pc, libzstd.pc.in is a
+pkg-config file for a multi-threaded static library.
+
+On calling make lib-mt, a libzstd.pc is generated for a multi-threaded
+static library as it's what asked by the user by forcing it.
+
+libzstd.pc is changed to PHONY to force regeneration of it on calling
+lib targets or install-pc to handle case where the same directory is
+used for mixed compilation.
+
+This was notice while migrating from meson to make build system where
+meson generates a correct .pc file while make doesn't.

+ 
+ For convenience, we provide a build target to generate multi and single threaded libraries:
+ - Force enable multithreading on both dynamic and static libraries by appending `-mt` to the target, e.g. `make lib-mt`.
++  Note that the `.pc` generated on calling `make lib-mt` will already include the require Libs and Cflags.
+ - Force disable multithreading on both dynamic and static libraries by appending `-nomt` to the target, e.g. `make lib-nomt`.
+ - By default, as mentioned before, dynamic library is multithreaded, and static library is single-threaded, e.g. `make lib`.
+ 
+ When linking a POSIX program with a multithreaded version of `libzstd`,
+ note that it's necessary to invoke the `-pthread` flag during link stage.
+ 
++The `.pc` generated from `make install` or `make install-pc` always assume a single-threaded static library
++is compiled. To correctly generate a `.pc` for the multi-threaded static library, set `MT=1` as ENV variable.
++
+ Multithreading capabilities are exposed
+ via the [advanced API defined in `lib/zstd.h`](https://github.com/facebook/zstd/blob/v1.4.3/lib/zstd.h#L351).
