- Update to version 0.5.0:
+ New features:
- --chmod changes permissions
- --clearenv unsets every environment variable (except PWD)
- --perms sets permissions for one subsequent --bind-data,
--dir, --file, --ro-bind-data or --tmpfs
+ Other enhancements:

+ Bug fixes:
- Use Python 3 for tests and examples
- Mount points for non-directories are created with permissions
-r--r--r-- instead of -rw-rw-rw-
- Don't remount items in /proc read-only if already EROFS,
required to run under Docker
- Allow mounting an non-directory over an existing
non-directory, e.g. --bind "$XDG_RUNTIME_DIR/my-log-socket"
/dev/log
- Silence kernel messages for our bind-mounts
- Make sure pkg-config is checked for, regardless of build
options
- Improve ability to bind-mount directories on case-insensitive
filesystems

Wed Apr 1 10:03:39 UTC 2020 - Sebastian Wagner <sebix+novell.com@sebix.at>
- Update to version 0.4.1:
* retcode: fix return code with syncfd and no event_fd
* Ensure we're always clearing the cap bounding set
* tests: Update output patterns for libcap >= 2.29
* Don't rely on geteuid() to know when to switch back from setuid root
* Don't support --userns2 in setuid mode
* fixes CVE-2020-5291
* fixes bsc#1168291
-------------------------------------------------------------------
Fri Dec 20 22:59:52 UTC 2019 - Bjørn Lie <bjorn.lie@gmail.com>
- Update to version 0.4.0:
+ The biggest feature in this release is the support for joining
existing user and pid namespaces. This doesn't work in the
setuid mode (at the moment).
+ Other changes:
- Stores namespace info in status json.
- In setuid mode pid 1 is now marked dumpable.
- Now builds with musl libc.

Fri Jun 7 14:38:21 UTC 2019 - Antonio Larrosa <alarrosa@suse.com>
- Use /bin/bash instead of /usr/bin/bash in SLE12
-------------------------------------------------------------------
Sat Jun 1 15:08:49 UTC 2019 - Sebastian Wagner <sebix+novell.com@sebix.at>
- Update to version 0.3.3:
- This release is the same as 0.3.2 but the version number in configure.ac
was accidentally still set to 0.3.1
- Update to version 0.3.2:
- fixes boo#1136958 / CVE-2019-12439
This release fixes a mostly theoretical security issue in unusual/broken
setups where `$XDG_RUNTIME_DIR` is unset.
There are some other smaller fixes, as well as an addition to the JSON
API that allows reading the inner process exit code, separately from
the `bwrap` exit code.
- Print "Out of memory" on stderr, not stdout
- bwrap: add option json-status-fd to show child exit code
- bwrap: Report COMMAND exit code in json-status-fd
- man page: Describe --chdir, not nonexistent --cwd
- Don't create our own temporary mount point for pivot_root
- Make lockdata long enough on 32-bit with 64-bit file pointers.
-------------------------------------------------------------------
Thu Oct 11 16:41:12 UTC 2018 - Antonio Larrosa <alarrosa@suse.com> - 0.3.1
- update to version 0.3.1:
* New feature in this release is --bind-try (as well as --dev-bind-try
and --ro-bind-try) which works like the regular versions if the source
exists, but does nothing if it doesn't exist.
* The mount type for the root tmpfs was also changed to "tmpfs" instead
of being empty, as the later could cause problems with some programs
when parsing the mountinfo files in /proc.
-------------------------------------------------------------------
Sat Jul 14 20:06:50 UTC 2018 - sebix+novell.com@sebix.at
- update to version 0.3.0:
* The biggest feature from this release is that bwrap
now supports being invoked recursively (from other container
runtimes such as Docker/podman/runc as well as bwrap itself)
when user namespaces are enabled, and the outer container manager
allows it (Docker's default seccomp policy doesn't).
* This is useful for testing scenarios; for example a project
uses Kubernetes for its CI, but inside build the project wants to run
each unit test in their own pid namespace, without going out
and creating a new pod for every single unit test.
* Similarly, rpm-ostree compose tree uses bwrap internally for scripts,
and we want to support running rpm-ostree inside a container as well.
* Another feature is bwrap now supports -- to terminate argument
parsing. To detect availablity of this, you could parse bwrap --version.
-------------------------------------------------------------------
Tue May 1 21:02:33 UTC 2018 - sebix+novell.com@sebix.at
- update to version 0.2.1:
* All the demos are included
* bugfixes for the demo files
* There was an issue with mkdir when running bubblewrap on an NFS
filesystem that has been fixed, so flatpak now works on NFS shares.
* Some leaks have been fixed, including a file descriptor leak.
-------------------------------------------------------------------
Mon Oct 9 17:53:37 UTC 2017 - sebix+novell.com@sebix.at
- update to version 0.2.0
- bwrap now automatically detects the new
user namespace restrictions in Red Hat Enterprise Linux 7.4:
bubblewrap: check for max_user_namespaces == 0.
- The most notable features are new arguments --as-pid1, and
--cap-add/--cap-drop. These were added for running systemd (or in general a
"full" init system) inside bubblewrap. But the capability options are also
useful for unprivileged callers to potentially retain capbilities inside the
sandbox (for example CAP_NET_ADMIN), when user namespaces are enabled.
Conversely, privileged callers (uid 0) can conversely drop capabilities (without
user namespaces). Contributed by Giuseppe Scrivano.
- With --dev, add /dev/fd and /dev/core symlinks
which should improve compatibility with older software.

Thu Mar 2 09:08:58 UTC 2017 - sebix+novell.com@sebix.at
- upgrade to upstream version 0.1.7
- note that this package was *never* affected by CVE-2017-5226
as it was introduced in version 0.1.6
- upstream changelog of version 0.1.7:
This release backs out the change in 0.1.6 which unconditionally
called setsid() in order to fix a security issue with TIOCSTI, aka
CVE-2017-522. That change caused some behavioural issues that are
hard to work with in some cases. For instance, it makes shell job
control not work for the bwrap command.
Instead there is now a new option --new-session which works like
0.1.6. It is recommended that you use this if possible, but if not we
recommended that you neutralize this some other way, for instance
using SECCOMP, which is what flatpak does:
https://github.com/flatpak/flatpak/commit/902fb713990a8f968ea4350c7c2a27ff46f1a6c4
In order to make it easy to create maximally safe sandboxes we have
also added a new commandline switch called --unshare-all. It unshares
all possible namespaces and is currently equivalent with:
--unshare-user-try --unshare-ipc --unshare-pid --unshare-net
--unshare-uts --unshare-cgroup-try
However, the intent is that as new namespaces are added to the kernel they will
be added to this list. Additionally, if --share-net is specified the network
namespace is not unshared.
This release also has some bugfixes:
bwrap reaps (unexpected) children that are inherited from the
parent, something which can happen if bwrap is part of a shell
pipeline.
bwrap clears the capability bounding set. The permitted
capabilities was already empty, and use of PR_NO_NEW_PRIVS should
make it impossible to increase the capabilities, but more
layers of protection is better.
The seccomp filter is now installed at the very end of bwrap, which
means the requirement of the filter is minimal. Any bwrap seccomp
filter must at least allow: execve, waitpid and write
Alexander Larsson (7):
Handle inherited children dying
Clear capability bounding set
Make the call to setsid() optional, with --new-session
demos/bubblewrap-shell.sh: Unshare all namespaces
Call setsid() and setexeccon() befor forking the init monitor
Install seccomp filter at the very end
Bump version to 0.1.7
Colin Walters (6):
Release 0.1.6
man: Correct namespace user -> mount
demo/shell: Add /var/tmp compat symlink, tweak PS1, add more docs
Release 0.1.6
ci: Combine ASAN and UBSAN
Add --unshare-all and --share-net
- upstream changelog for 0.1.6:
This fixes a security issue with TIOCSTI, aka CVE-2017-522. Note bubblewrap is
far from the only program that has this issue, and I think the best fix is
probably in the kernel to support disabling this ioctl.
Programs can also work around this by calling setsid() on their own in an exec
handler before doing an exevp("bwrap").
- upstream changelog for 0.1.5:
This is a bugfix release, here are the major changes:
Running bubblewrap as root now works again
Various fixes for the testsuite
Use same default compiler warnings as ostree
Handle errors resolving symlinks during bind mounts
Alexander Larsson (2):
bind-mount: Check for errors in realpath()
Bump version to 0.1.5
Colin Walters (6):
Don't call capset() unless we need to
Only --unshare-user automatically if we're not root
ci: Modernize a bit, add f25-ubsan
README.md: Update with better one liner and more information
utils: Add __attribute__((printf)) to die()
build: Sync default warning -> error set from ostree
Simon McVittie (4):
test-run: be a bash script
test-run: don't assume we are uid 1000
Adapt tests so they can be run against installed binaries
Fix incorrect nesting of backticks when finding a FUSE mount
