+Description: Move tests that trigger -Warray-bounds to separate compilation unit
+ GCC 10 is now smart enough to detect violation of array boundaries that tests
+ are actually tested. Along with -Werror this led to tests failure, so I move
+ such tests to another compilation unit to have the warning deactivated for
+ only these tests.

+Subject: [PATCH] sim/ppc: Fix linker error with -fno-common
+
+GCC 10 enables -fno-common by default.  This resulted in a multiple
+definition linker error since global variables were declared and defined
+in a header file:
+
+  ld: ld-insn.o:sim/ppc/ld-insn.h:221: multiple definition of
+  `max_model_fields_len'; igen.o:sim/ppc/ld-insn.h:221: first defined here
+
+sim/ppc
+
+	* ld-insn.h (last_model, last_model_data, last_model_function,
+	last_model_internal, last_model_macro, last_model_static):
+	Delete.
+	(max_model_fields_len, model_data, model_functions,
+	model_internal, model_macros, model_static, models): Declare, but do not
+	define.
+	* ld-insn.c (last_model, last_model_data, last_model_function,
+	last_model_internal, last_model_macro, last_model_static,
+	max_model_fields_len, model_data, model_functions,
+	model_internal, model_macros, model_static, models): Define.
+
+(cherry picked from commit ad8464f799a4c96c7ab8bdfec3f95846cf54f9b0)

+
+This patch is a trivial backport from the upstream commit mentioned above.

+Subject: [PATCH] meson: allow building with elogind
+
+Currently, the GDM meson build has a hard dependency on systemd.
+However, GDM can function just fine if one is using elogind. This allows
+a user to build GDM against libelogind and also disable the systemd
+system and user units.

-Subject: [PATCH] gbytearray: Do not accept too large byte arrays
-
-GByteArray uses guint for storing the length of the byte array, but it
-also has a constructor (g_byte_array_new_take) that takes length as a
-gsize. gsize may be larger than guint (64 bits for gsize vs 32 bits
-for guint). It is possible to call the function with a value greater
-than G_MAXUINT, which will result in silent length truncation. This
-may happen as a result of unreffing GBytes into GByteArray, so rather
-be loud about it.
-
-(Test case tweaked by Philip Withnall.)
-
-(Backport 2.66: Add #include gstrfuncsprivate.h in the test case for
-`g_memdup2()`.)

-Subject: [PATCH 01/11] gstrfuncs: Add internal g_memdup2() function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This will replace the existing `g_memdup()` function for use within
-GLib. It has an unavoidable security flaw of taking its `byte_size`
-argument as a `guint` rather than as a `gsize`. Most callers will
-expect it to be a `gsize`, and may pass in large values which could
-silently be truncated, resulting in an undersize allocation compared
-to what the caller expects.
-
-This could lead to a classic buffer overflow vulnerability for many
-callers of `g_memdup()`.
-
-`g_memdup2()`, in comparison, takes its `byte_size` as a `gsize`.
-
-Spotted by Kevin Backhouse of GHSL.
-
-In GLib 2.68, `g_memdup2()` will be a new public API. In this version
-for backport to older stable releases, it’s a new `static inline` API
-in a private header, so that use of `g_memdup()` within GLib can be
-fixed without adding a new API in a stable release series.

-Subject: [PATCH 04/11] glib: Use g_memdup2() instead of g_memdup() in obvious
- places
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Convert all the call sites which use `g_memdup()`’s length argument
-trivially (for example, by passing a `sizeof()` or an existing `gsize`
-variable), so that they use `g_memdup2()` instead.
-
-In almost all of these cases the use of `g_memdup()` would not have
-caused problems, but it will soon be deprecated, so best port away from
-it
-
-In particular, this fixes an overflow within `g_bytes_new()`, identified
-as GHSL-2021-045 by GHSL team member Kevin Backhouse.
-
-Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
-Fixes: GHSL-2021-045

-Subject: [PATCH 05/11] gwinhttpfile: Avoid arithmetic overflow when
- calculating a size
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The members of `URL_COMPONENTS` (`winhttp_file->url`) are `DWORD`s, i.e.
-32-bit unsigned integers. Adding to and multiplying them may cause them
-to overflow the unsigned integer bounds, even if the result is passed to
-`g_memdup2()` which accepts a `gsize`.
-
-Cast the `URL_COMPONENTS` members to `gsize` first to ensure that the
-arithmetic is done in terms of `gsize`s rather than unsigned integers.
-
-Spotted by Sebastian Dröge.

-Subject: [PATCH 06/11] gdatainputstream: Handle stop_chars_len internally as
- gsize
-
-Previously it was handled as a `gssize`, which meant that if the
-`stop_chars` string was longer than `G_MAXSSIZE` there would be an
-overflow.

-Subject: [PATCH 08/11] gkeyfilesettingsbackend: Handle long keys when
- converting paths
-
-Previously, the code in `convert_path()` could not handle keys longer
-than `G_MAXINT`, and would overflow if that was exceeded.
-
-Convert the code to use `gsize` and `g_memdup2()` throughout, and
-change from identifying the position of the final slash in the string
-using a signed offset `i`, to using a pointer to the character (and
-`strrchr()`). This allows the slash to be at any position in a
-`G_MAXSIZE`-long string, without sacrificing a bit of the offset for
-indicating whether a slash was found.

-Don’t use an `int`, that’s potentially too small. In practical terms,

-
-By making these changes we can use `g_memdup2()` without warnings,

-Subject: [PATCH 11/11] giochannel: Forbid very long line terminator strings
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The public API `GIOChannel.line_term_len` is only a `guint`. Ensure that
-nul-terminated strings passed to `g_io_channel_set_line_term()` can’t
-exceed that length. Use `g_memdup2()` to avoid a warning (`g_memdup()`
-is due to be deprecated), but not to avoid a bug, since it’s also
-limited to `G_MAXUINT`.

-Subject: [PATCH 1/3] gkeyfilesettingsbackend: Fix basename handling when group
- is unset
-
-Fix an effective regression in commit
-7781a9cbd2fd0aa84bee0f4eee88470640ff6706, which happens when
-`convert_path()` is called with a `key` which contains no slashes. In
-that case, the `key` is entirely the `basename`.
-
-Prior to commit 7781a9cb, the code worked through a fluke of `i == -1`
-cancelling out with the various additions in the `g_memdup()` call, and
-effectively resulting in `g_strdup (key)`.
-
-Spotted by Guido Berhoerster.

-Subject: [PATCH] glocalfileoutputstream: Fix CREATE_REPLACE_DESTINATION
- with symlinks
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The `G_FILE_CREATE_REPLACE_DESTINATION` flag is equivalent to unlinking
-the destination file and re-creating it from scratch. That did
-previously work, but in the process the code would call `open(O_CREAT)`
-on the file. If the file was a dangling symlink, this would create the
-destination file (empty). That’s not an intended side-effect, and has
-security implications if the symlink is controlled by a lower-privileged
-process.
-
-Fix that by not opening the destination file if it’s a symlink, and
-adjusting the rest of the code to cope with
- - the fact that `fd == -1` is not an error iff `is_symlink` is true,
- - and that `original_stat` will contain the `lstat()` results for the
-   symlink now, rather than the `stat()` results for its target (again,
-   iff `is_symlink` is true).
-
-This means that the target of the dangling symlink is no longer created,
-which was the bug. The symlink itself continues to be replaced (as
-before) with the new file — this is the intended behaviour of
-`g_file_replace()`.
-
-The behaviour for non-symlink cases, or cases where the symlink was not
-dangling, should be unchanged.
-
-Includes a unit test.
-
-Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
-
-Fixes: #2325

-Subject: [PATCH] [BZ #22342] Fix netgroup cache keys.
-
-Unlike other nscd caches, the netgroup cache contains two types of
-records - those for "iterate through a netgroup" (i.e. setnetgrent())
-and those for "is this user in this netgroup" (i.e. innetgr()),
-i.e. full and partial records.  The timeout code assumes these records
-have the same key for the group name, so that the collection of records
-that is "this netgroup" can be expired as a unit.
-
-However, the keys are not the same, as the in-netgroup key is generated
-by nscd rather than being passed to it from elsewhere, and is generated
-without the trailing NUL.  All other keys have the trailing NUL, and as
-noted in the linked BZ, debug statements confirm that two keys for the
-same netgroup are added to the cache with two different lengths.
-
-The result of this is that as records in the cache expire, the purge
-code only cleans out one of the two types of entries, resulting in
-stale, possibly incorrect, and possibly inconsistent cache data.
-
-The patch simply includes the existing NUL in the computation for the
-key length ('key' points to the char after the NUL, and 'group' to the
-first char of the group, so 'key-group' includes the first char to the
-NUL, inclusive).
-
-	[BZ #22342]
-	* nscd/netgroupcache.c (addinnetgrX): Include trailing NUL in
-	key value.

-Subject: [PATCH] i386: Fix i386 sigaction sa_restorer initialization
- (BZ#21269)
-
-This patch fixes the i386 sa_restorer field initialization for sigaction
-syscall for kernel with vDSO.  As described in bug report, i386 Linux
-(and compat on x86_64) interprets SA_RESTORER clear with nonzero
-sa_restorer as a request for stack switching if the SS segment is 'funny'.
-This means that anything that tries to mix glibc's signal handling with
-segmentation (for instance through modify_ldt syscall) is randomly broken
-depending on what values lands in sa_restorer.
-
-The testcase added  is based on Linux test tools/testing/selftests/x86/ldt_gdt.c,
-more specifically in do_multicpu_tests function.  The main changes are:
-
-  - C11 atomics instead of plain access.
-
-  - Remove x86_64 support which simplifies the syscall handling and fallbacks.
-
-  - Replicate only the test required to trigger the issue.
-
-Checked on i686-linux-gnu.
-
-	[BZ #21269]
-	* sysdeps/unix/sysv/linux/i386/Makefile (tests): Add tst-bz21269.
-	* sysdeps/unix/sysv/linux/i386/sigaction.c (SET_SA_RESTORER): Clear
-	sa_restorer for vDSO case.
-	* sysdeps/unix/sysv/linux/i386/tst-bz21269.c: New file.

+This is needed to run Python on the Hurd, especially during the build of
+python-boot0.
+
+Adapted from https://salsa.debian.org/glibc-team/glibc/-/blob/glibc-2.31/debian/patches/hurd-i386/unsubmitted-clock_t_centiseconds.diff
+
+Use the realtime clock for the monotonic clock. This is of course not a proper
+implementation (which is being done in Mach), but will permit to fix at least
+the iceweasel stack.
+
+vlc however doesn't build when _POSIX_CLOCK_SELECTION is enabled but
+_POSIX_TIMERS is not, and they refuse to fix that (see #765578), so disable the
+former.

-Subject: [PATCH] loginDialog: Reset auth prompt on vt switch before fade in
-
-At the moment, if a user switches to the login screen vt,
-the login screen fades in whatever was on screen prior, and
-then does a reset.
-
-It makes more sense to reset first, so we fade in what the
-user is going to interact with instead of what they interacted
-with before.
-
-Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2997

-Subject: [PATCH] fix: out-of-bounds write on invalid label
-
-When the label for a node cannot be parsed (due to it being malformed), it falls
-back on the symbol name of the node itself. I.e. the default label the node
-would have had if it had no label attribute at all. However, this is applied by
-dynamically altering the node's label to "\N", a shortcut for the symbol name of
-the node. All of this is fine, however if the hand written label itself is
-shorter than the literal string "\N", not enough memory would have been
-allocated to write "\N" into the label text.
-
-Here we account for the possibility of error during label parsing, and assume
-that the label text may need to be overwritten with "\N" after the fact. Fixes
-issue #1700.

+
+This patch makes GTK look for additional modules in a list of directories
+specified by the environment variable "GUIX_GTK4_PATH". This can be used
+instead of "GTK_PATH" to make GTK find modules that are incompatible with
+other major versions of GTK.

+Subject: [PATCH] tests: Fix test suite for Guile 3.0.5.
+
+The test-runner object is now reset to #f when calling the 'test-end'

+Guile (srfi-64: Reset test-runner-current if done) which introduced this
+change.
+
+* tests/client-server.scm (exit-status): New variable.  Use it when calling
+exit.
+* tests/dist.scm: Likewise.
+* tests/key.scm: Likewise.
+* tests/log.scm: Likewise.

-Subject: [PATCH 35/35] telnet: Several ioctls have been disabled in the Hurd's
- glibc
-
-But not the related option macros. inetutils uses those macros to decide
-whether the ioctls are available, so it is FTBFS now. The Hurd's glibc
-is being fixed, but we'll use this for now to get the builds going.

-Description: Fix client code for hurd, avoiding malloc overflow
- When trying to setup a inet connection, it happens the following:
- - in libtirp, src/clnt_vc.c, clnt_vc_create gets called
- - when trying to allocate vc_fd_locks, __rpc_dtbsize() is used as size
-   for that array of fd locks
- - __rpc_dtbsize(), in src/rpc_generic.c, queries using rlimit the
-   maximum (rlim_max) number of file descriptors (RLIMIT_NOFILE):
-   - on Linux, the default is { rlim_cur = 1024, rlim_max = 4096 }
-   - on kFreeBSD, the default is { rlim_cur = 1024, rlim_max = 1024 }
-   - on Hurd, the default is { rlim_cur = 1024, rlim_max = RLIM_INFINITY }
-  meaning that on Hurd the memory allocation fails (as
-  __rpc_dtbsize() * sizeof(int) overflows and is negative)
-
- Change libtiprc so __rpc_dtbsize falls back on rlim_cur if rlim_max
- is unlimited.
-
- This patch fixes the client connection using inet sockets; local unix
- sockets are not working, for two reasons so far:
- - getpeername on them gives EOPNOTSUPP
- - SO_REUSEADDR is not implemented for them

-Work around a problem arising from the update to OpenSSL 1.0.2f, based on the
-following upstream commit:
-
-  https://github.com/noxxi/p5-io-socket-ssl/commit/6e23ee4a433f83f1065bd2467255eba5ee9b1ddd
-
-Attempting to update to IO-Socket-SSL-2.023, which includes this commit,
-caused other test failures.  See:
-
-  https://lists.gnu.org/archive/html/guix-devel/2016-01/msg01032.html
-
-Description from the upstream commit:
-
-  OpenSSL 1.0.2f changed the behavior of SSL shutdown in case the TLS connection
-  was not fully established (commit: f73c737c7ac908c5d6407c419769123392a3b0a9).
-  This somehow resulted in Net::SSLeay::shutdown returning 0 (i.e. keep trying)
-  which caused an endless loop. It will now ignore this result in case the TLS
-  connection was not yet established and consider the TLS connection closed
-  instead.

+Subject: [PATCH] fix tests when using Python 3.9a6
+
+In Python 3.9a6 integer values for future flags were changed to prevent
+collision with compiler flags. We need to retrieve these at runtime so
+the test suite works with Python <= 3.8 as well as Python 3.9.

+Subject: [PATCH] Let Bison generate the header directly, to fix build with
+ Bison 3.7
+
+Starting with Bison 3.7, the generated C++ file #include's the header
+by default, instead of duplicating it. So we should not delete it.
+
+Remove the code to add #ifdef guards to the header, since Bison adds
+them itself since version 2.6.3.

+Subject: [PATCH] Work around broken integration with latest libc++. (#1635)
+
+* Work around broken integration with latest libc++.
+
+In newer versions of libc++, the base template of std::iterator_traits
+provides a member typedef called __primary_template which is an alias
+to the std::iterator_traits specialization itself. This fix works with
+both the old version of libc++ and the new one.
+
+Fixes issue #1633.
+
+* Fix is_std_iterator_traits_specialized_v on MSVC
+
+It used to pretend that std::iterator_traits<T*> is a user-defined
+specialization, which isn't the case. This is due to MSVC's
+iterator_traits<T*> specialization not posing as the base template.

-Description: fix race condition allowing attackers to access destination file
- This commit addresses https://github.com/facebook/zstd/issues/2491.
- .
- Note that a downside of this solution is that it is global: `umask()` affects
- all file creation calls in the process. I believe this is safe since
- `fileio.c` functions should only ever be used in the zstd binary, and these
- are (almost) the only files ever created by zstd, and AIUI they're only
- created in a single thread. So we can get away with messing with global state.
- .
- Note that this doesn't change the permissions of files created by `dibio.c`.
- I'm not sure what those should be...

        "The PSNFSS collection includes a set of files that provide a complete
 working setup of the LaTeX font selection scheme (NFSS2) for use with common
-PostScript fonts.  It covers the so-called \"Base\" fonts (which are built
-into any Level 2 PostScript printing device and the Ghostscript interpreter)
-and a number of free fonts.  It provides font definition files, macros and
-font metrics.  The bundle as a whole is part of the LaTeX required set of
-packages.")
+PostScript fonts.  The base set of text fonts covered by PSNFSS includes the
+AvantGarde, Bookman, Courier, Helvetica, New Century Schoolbook, Palatino,
+Symbol, Times Roman and Zapf Dingbats fonts.  In addition, the fonts Bitstream
+Charter and Adobe Utopia are covered.  Separate packages are provided to load
+each font for use as the main text font.  The package @code{helvet} allows
+Helvetica to be loaded with its size scaled to something more appropriate for
+use as a Sans-Serif font to match Times, while @code{pifont} provides the
+means to select single glyphs from symbol fonts.  The bundle as a whole is
+part of the LaTeX required set of packages.")

+of ‘line styles’ for each sectioning level used in the document.
+
+The package provides its own custom line styles (which may be used as
+examples), and continues to support the standard formatting inherited from
+the LaTeX document classes, but the package can also allow the user to
+delegate the details to packages dealing with list making environments (such
+as enumitem).  The package’s default global style typesets tables of contents
+in a multi-column format, with either a standard heading, or a ruled title
+(optionally with a frame around the table).
+
+The @code{\\tableofcontents} command may be used arbitrarily many times in
+the same document, while @code{\\localtableofcontents} provides a ‘local’
+table of contents.")
