-This also serves as a bug fix when a previously synced note segment

-
-since the PT_NOTE section at 2f4 covers [2] and [3] but the code
-calclates curr_off should be 314, not the 318 in the binary. This
-is an alignment issue.
-
-To fix this, we need to round curr_off to the next section alignment.

+If we link against a newer glibc 2.34 and then try and our LD_PRELOAD is run against a
+binary on a host with an older libc, we see symbol errors since in glibc 2.34, pthread 
+and dl are merged into libc itself.
+
+We need to use the older form of linking so use glibc binaries from an older release
+to force this. We only use minimal symbols from these anyway.
+
+pthread_atfork is problematic, particularly on arm so use the internal glibc routine
+it maps too. This was always present in the main libc from 2.3.2 onwards.
+
+Yes this is horrible. Better solutions welcome.

+## Introduction
+
+This provides the Rust compiler, tools for building packages (cargo), and 
+a few example projects.
+
+## What works:
+
+ - Building `rust-native` and `cargo-native`
+ - Building Rust based projects with Cargo for the TARGET
+   - e.g. `rustfmt` which is used by the CI system
+ - `-buildsdk` and `-crosssdk` packages
+
+## What doesn't:
+
+ - Using anything but x86_64 or arm64 as the build environment
+ - rust (built for target) [issue #81](https://github.com/meta-rust/meta-rust/issues/81)
+
+## What's untested:
+
+ - cargo (built for target)
+
+## Building a rust package
+
+When building a rust package in bitbake, it's usually easiest to build with
+cargo using cargo.bbclass.  If the package already has a Cargo.toml file (most
+rust packages do), then it's especially easy.  Otherwise you should probably
+get the code building in cargo first. 
+
+Once your package builds in cargo, you can use
+[cargo-bitbake](https://github.com/cardoe/cargo-bitbake) to generate a bitbake
+recipe for it.  This allows bitbake to fetch all the necessary dependent
+crates, as well as a pegged version of the crates.io index, to ensure maximum
+reproducibility. Once the Rust SDK support is added to oe-core, cargo-bitbake
+may also be added to the SDK.
+
+NOTE: You will have to edit the generated recipe based on the comments
+contained within it
+
+## TODO
+
+## Pitfalls
+
+ - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way Rust configuration options are tracked for different targets. This is the reason we use the Yocto triples instead of the native Rust triples. See rust-lang/cargo#3349.
+
+## Dependencies
+
+On the host:
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
+
+On the target:
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
+
+## Copyright
+
+MIT OR Apache-2.0 - Same as rust

+Date: Fri, 19 May 2017 00:22:57 -0700
+Subject: [PATCH 12/18] llvm: allow env override of exe path
+
+When using a native llvm-config from inside a sysroot, we need llvm-config to
+return the libraries, include directories, etc. from inside the sysroot rather
+than from the native sysroot. Thus provide an env override for calling
+llvm-config from a target sysroot.

-Subject: [PATCH] squashfs-tools: fix build failure against gcc-10
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-On gcc-10 (and gcc-9 -fno-common) build fails as:
-
-```
-cc ... -o mksquashfs
-ld: read_fs.o:(.bss+0x0):
-  multiple definition of `fwriter_buffer'; mksquashfs.o:(.bss+0x400c90): first defined here
-ld: read_fs.o:(.bss+0x8):
-  multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400c98): first defined here
-```
-
-gcc-10 will change the default from -fcommon to fno-common:
-https://gcc.gnu.org/PR85678.
-
-The error also happens if CFLAGS=-fno-common passed explicitly.

+Subject: [PATCH] Avoid use of INSTALL_DIR for symlink targets
+
+In case INSTALL_DIR is overridden with a staged install location, using
+INSTALL_DIR for the symlink target path prefix will yield an incorrect location
+for the final installation.
+
+Because the symlink itself is already installed to INSTALL_DIR, simply removing
+the INSTALL_DIR prefix suffices as a fix.
+
+Note that using $DESTDIR/$INSTALL_DIR where appropriate can avoid this type of
+issue, but that can be considered a future enhancement.
