Stable branch bug fix and security release. One patch updated, three removed since they are no longer needed
Changes (from release notes): Fix potential relative read when calling g_printerr(), which could lead to a denial of service from a setuid-root process being used to block access to the TTY for another user (#1919) Fix SOCKS proxy resolver sometimes not being used when resolving addresses via Happy Eyeballs (CVE-2020-6750) (#1989) Several other Happy Eyeballs fixes for address resolution (#1871, #1872, #1902) Fix parsing of full Julian day range from $TZ environment variable (#1999) Several race condition/crash fixes (!1353, !1357) Bugs fixed: 1919 read from relative path in g_printerr() in 2.58.3 1995 Tracker issue for Happy Eyeballs regressions 1999 GTimeZone fails to accept full Julian day range when parsing the direct $TZ string format 1323 Backport !1314 “gtimezone: fix parsing of Julian day in POSIX TZ format” to glib-2-62 1331 Backport !1330 “W32: Correctly set st_ino when doing private stat()” to glib-2-62 1352 Backport !1351 “glib.supp: update g-threaded-resolver-getaddrinfo-config” to glib-2-62 1361 Backport !1353 GMainContext source reference fixes to glib-2-62 1365 Refactor g_socket_client_connect_async() 1370 Backport !1369 “build: Rework path construction to reliably add prefix” to glib-2-62 1371 Backport !1357 “gunixmounts: Make GUnixMountMonitor thread-safe” to glib-2-62 Signed-off-by: Steve Sakoman <st...@sakoman.com> --- ...t-write-bindir-into-pkg-config-files.patch | 2 +- ...-GSource-iterator-if-iteration-can-m.patch | 43 ------- ...-memory-leaks-and-memory-corruption-.patch | 109 ------------------ ...e-mutex-unlocking-in-destructor-righ.patch | 36 ------ ...{glib-2.0_2.62.4.bb => glib-2.0_2.62.5.bb} | 7 +- 5 files changed, 3 insertions(+), 194 deletions(-) delete mode 100644 meta/recipes-core/glib-2.0/glib-2.0/0011-GMainContext-Fix-GSource-iterator-if-iteration-can-m.patch delete mode 100644 meta/recipes-core/glib-2.0/glib-2.0/0012-GMainContext-Fix-memory-leaks-and-memory-corruption-.patch delete mode 100644 meta/recipes-core/glib-2.0/glib-2.0/0013-GMainContext-Move-mutex-unlocking-in-destructor-righ.patch rename meta/recipes-core/glib-2.0/{glib-2.0_2.62.4.bb => glib-2.0_2.62.5.bb} (83%) diff --git a/meta/recipes-core/glib-2.0/glib-2.0/0001-Do-not-write-bindir-into-pkg-config-files.patch b/meta/recipes-core/glib-2.0/glib-2.0/0001-Do-not-write-bindir-into-pkg-config-files.patch index edac4c9f75..8dd959b7e2 100644 --- a/meta/recipes-core/glib-2.0/glib-2.0/0001-Do-not-write-bindir-into-pkg-config-files.patch +++ b/meta/recipes-core/glib-2.0/glib-2.0/0001-Do-not-write-bindir-into-pkg-config-files.patch @@ -22,7 +22,7 @@ index 71e88c4..8ce3987 100644 @@ -831,14 +831,14 @@ pkg.generate(libgio, 'schemasdir=' + join_paths('${datadir}', schemas_subdir), 'bindir=' + join_paths('${prefix}', get_option('bindir')), - 'giomoduledir=' + giomodulesdir, + 'giomoduledir=' + pkgconfig_giomodulesdir, - 'gio=' + join_paths('${bindir}', 'gio'), - 'gio_querymodules=' + join_paths('${bindir}', 'gio-querymodules'), - 'glib_compile_schemas=' + join_paths('${bindir}', 'glib-compile-schemas'), diff --git a/meta/recipes-core/glib-2.0/glib-2.0/0011-GMainContext-Fix-GSource-iterator-if-iteration-can-m.patch b/meta/recipes-core/glib-2.0/glib-2.0/0011-GMainContext-Fix-GSource-iterator-if-iteration-can-m.patch deleted file mode 100644 index 37b77d567c..0000000000 --- a/meta/recipes-core/glib-2.0/glib-2.0/0011-GMainContext-Fix-GSource-iterator-if-iteration-can-m.patch +++ /dev/null @@ -1,43 +0,0 @@ -From ef2be42998e3fc10299055a5a01f7c791538174c Mon Sep 17 00:00:00 2001 -From: =?UTF-8?q?Sebastian=20Dr=C3=B6ge?= <sebast...@centricular.com> -Date: Mon, 3 Feb 2020 15:38:28 +0200 -Subject: [PATCH] GMainContext - Fix GSource iterator if iteration can modify - the list - -We first have to ref the next source and then unref the previous one. -This might be the last reference to the previous source, and freeing the -previous source might unref and free the next one which would then leave -use with a dangling pointer here. - -Fixes https://gitlab.gnome.org/GNOME/glib/issues/2031 - -Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/glib/-/commit/b06c48de7554607ff3fb58d6c0510cfa5088e909] - ---- - glib/gmain.c | 8 ++++++-- - 1 file changed, 6 insertions(+), 2 deletions(-) - -diff --git a/glib/gmain.c b/glib/gmain.c -index af979c8..a9a287d 100644 ---- a/glib/gmain.c -+++ b/glib/gmain.c -@@ -969,13 +969,17 @@ g_source_iter_next (GSourceIter *iter, GSource **source) - * GSourceList to be removed from source_lists (if iter->source is - * the only source in its list, and it is destroyed), so we have to - * keep it reffed until after we advance iter->current_list, above. -+ * -+ * Also we first have to ref the next source before unreffing the -+ * previous one as unreffing the previous source can potentially -+ * free the next one. - */ -+ if (next_source && iter->may_modify) -+ g_source_ref (next_source);
