Subject: [PATCH] QLibrary: fix deadlock caused by fix to QTBUG-39642

Commit ae6f73e8566fa76470937aca737141183929a5ec inserted a mutex around
the entire load_sys(). We had reasoed that deadlocks would only occur if
the object creation in instance() recursed into its own instance(),
which was already a bug. But we had forgotten that dlopen()/
LoadLibrary() executes initialization code from the module being loaded,
which could cause a recursion back into the same QPluginLoader or
QLibrary object. This recursion is benign because the module *is* loaded
and dlopen()/LoadLibrary() returns the same handle.

[ChangeLog][QtCore][QLibrary and QPluginLoader] Fixed a deadlock that
would happen if the plugin or library being loaded has load-time
initialization code (C++ global variables) that recursed back into the
same QLibrary or QPluginLoader object.

PS: QLibraryPrivate::loadPlugin() updates pluginState outside a mutex
lock, so pluginState should be made an atomic variable. Once that is
done, we'll only need locking the mutex to update errorString (no
locking before loading).

Subject: [PATCH] common: Disable enum type stream operators for Qt >= 5.14

Starting from version 5.14, Qt provides stream operators for enum
types, which collide with the ones we ship in types.h. Disable
Quassel's stream operators when compiling against Qt 5.14 or later.

Add a unit test that ensures that enum serialization honors the width
of the underlying type.

code:
Racket uses checksums to test if it needs to recompile its source
files to bytecode.  If Racket is updated by grafting, the source and
bytecode files get updated, but the checksum stays the same.  Since
the checksum no longer matches the source file, Racket tries to
regenerate the bytecode and write it to the store, causing errors
because the store is immutable.  This patch makes Racket ignore
checksums for files in the store.

See <https://debbugs.gnu.org/30680> for details.

Subject: [PATCH 031/176] RCORE: compile fixes for KUbuntu 16.04/gcc
 5.3.1-14ubuntu2

Rapicorn uses isnan(...) and isinf(...) from cmath.h, however on KUbuntu 16.04
it should use std::isnan(...) and std::isinf(...) instead. Patch below.

    [C slog] Move ‘exiting’ to beginning of func decl.

    Apparently, ‘gcc --std=c11’ does not abide the ‘exiting’
    attribute appearing at the end of the func decl.
    Reported by Romain Francoise.

			   =====================

Readline-Release: 6.3
Patch-ID: readline63-003

Bug-Reported-by:

Bug-Description:

There are debugging functions in the readline release that are theoretically
exploitable as security problems.  They are not public functions, but have
global linkage.

Patch (apply with `patch -p0'):

code:
This patch is to make sure that `libncurses' is among the `NEEDED'
dependencies of `libreadline.so' and `libhistory.so'.

Failing to do that, applications linking against Readline are
forced to explicitly link against libncurses as well; in addition,
this trick doesn't work when using GNU ld's `--as-needed'.

code:
Purity: don't look for library dependencies (of the form `-lfoo') in
/lib and /usr/lib.  Likewise, when searching for included Makefiles,
don't look in /usr/include and friends.

Borrowed from similar patch for GNU Make and adjusted for Remake.

Subject: [PATCH 3/3] Add external version.cmake.

This file is maintained in an external repository.  It is only
included in released versions.  For building snapshots of RNP, a fixed
snapshot of version.cmake is downloaded on demand.  To avoid this,
this patch explicitly provides the file.

This patch removes Rubocop extensions from Rubocop's closure to break
a dependency cycle with itself.

corresponding directives.

Subject: [PATCH] nsenter: clone /proc/self/exe to avoid exposing host binary
 to container

There are quite a few circumstances where /proc/self/exe pointing to a
pretty important container binary is a _bad_ thing, so to avoid this we
have to make a copy (preferably doing self-clean-up and not being
writeable).

We require memfd_create(2) -- though there is an O_TMPFILE fallback --
but we can always extend this to use a scratch MNT_DETACH overlayfs or
tmpfs. The main downside to this approach is no page-cache sharing for
the runc binary (which overlayfs would give us) but this is far less
complicated.

This is only done during nsenter so that it happens transparently to the
Go code, and any libcontainer users benefit from it. This also makes
ExtraFiles and --preserve-fds handling trivial (because we don't need to
worry about it).
