| static-linux-user-stubs.diff | static linux-user stubs When building a static linux-user binaries, ld complains: /usr/bin/ld: libglib-2.0.a(gutils.c.o): in function `g_get_user_database_entry': warning: Using 'getpwuid' in statically linked applications requires... warning: Using 'getpwnam_r' in statically linked applications requires... warning: Using 'getpwuid_r' in statically linked applications requires... This is because glib, in their "misc utils" unit (gutils.c), has functions to return current user home directory and similar stuff, and this unit is almost always included into the link, even if these particular functions aren't used by the application. Ideally this should be fixed on the glib side, by splitting gutils.c into several files, so unused symbols wont be included in the link at all. But this requires extra efforts from glib side, and static linkage with glib is very rare. So just stub-out a few getpw* symbols here, - this will eliminate the warning and will make resulting binary quite a bit smaller. It would be nice to eliminate whole dlopen() too. diff --git a/linux-user/main.c b/linux-user/main.c |

| linux-user-binfmt-P.diff | [PATCH, HACK]: linux-user: handle binfmt-misc P flag as a separate exe name A hackish way to distinguish the case when qemu-user binary is executed using in-kernel binfmt-misc subsystem with P flag (preserve argv). We register binfmt interpreter under name /usr/libexec/qemu-binfmt/qemu-foo-binfmt-P (which is just a symlink to ../../bin/qemu-foo), and if run like that, qemu-user binary will "know" it should interpret argv[1] & argv[2] in a special way. diff --git a/linux-user/main.c b/linux-user/main.c index 9277df2e9d..bd323f70bc 100644 |

| note-missing-module-pkg-name.diff | Note missing module package name Debian ships different modules in different packages. By default qemu ignores the fact that it can not load a module, pretending this module never existed. Give a useful hint about the package where the module in question resides. This is a hack, but it makes qemu packaged in debian more user-friendly. diff --git a/audio/audio.c b/audio/audio.c index 7ac74f9e16..15f1071bdc 100644 |

| 9pfs-fix-regression-regarding-CVE-2023-2861.patch | 9pfs: fix regression regarding CVE-2023-2861 The released fix for this CVE: f6b0de53fb8 ("9pfs: prevent opening special files (CVE-2023-2861)") caused a regression with security_model=passthrough. When handling a 'Tmknod' request there was a side effect that 'Tmknod' request could fail as 9p server was trying to adjust permissions: #6 close_if_special_file (fd=30) at ../hw/9pfs/9p-util.h:140 #7 openat_file (mode=<optimized out>, flags=2228224, name=<optimized out>, dirfd=<optimized out>) at ../hw/9pfs/9p-util.h:181 #8 fchmodat_nofollow (dirfd=dirfd@entry=31, name=name@entry=0x5555577ea6e0 "mysocket", mode=493) at ../hw/9pfs/9p-local.c:360 #9 local_set_cred_passthrough (credp=0x7ffbbc4ace10, name=0x5555577ea6e0 "mysocket", dirfd=31, fs_ctx=0x55555811f528) at ../hw/9pfs/9p-local.c:457 #10 local_mknod (fs_ctx=0x55555811f528, dir_path=<optimized out>, name=0x5555577ea6e0 "mysocket", credp=0x7ffbbc4ace10) at ../hw/9pfs/9p-local.c:702 #11 v9fs_co_mknod (pdu=pdu@entry=0x555558121140, fidp=fidp@entry=0x5555574c46c0, name=name@entry=0x7ffbbc4aced0, uid=1000, gid=1000, dev=<optimized out>, mode=49645, stbuf=0x7ffbbc4acef0) at ../hw/9pfs/cofs.c:205 #12 v9fs_mknod (opaque=0x555558121140) at ../hw/9pfs/9p.c:3711 That's because server was opening the special file to adjust permissions, however it was using O_PATH and it would have not returned the file descriptor to guest. So the call to close_if_special_file() on that branch was incorrect. Let's lift the restriction introduced by f6b0de53fb8 such that it would allow to open special files on host if O_PATH flag is supplied, not only for 9p server's own operations as described above, but also for any client 'Topen' request. It is safe to allow opening special files with O_PATH on host, because O_PATH only allows path based operations on the resulting file descriptor and prevents I/O such as read() and write() on that file descriptor.

| tcg-Reset-free_temps-before-tcg_optimize.patch | tcg: Reset free_temps before tcg_optimize When allocating new temps during tcg_optmize, do not re-use any EBB temps that were used within the TB. We do not have any idea what span of the TB in which the temp was live. Introduce tcg_temp_ebb_reset_freed and use before tcg_optimize, as well as replacing the equivalent in plugin_gen_inject and tcg_func_start.
