Which means it's not +part of the qemu-kvm git tree anymore. + +This passed unoticed for RHEL-AV-8.0.1 and 8.1.0 because qemu still ships +the code in the tarball. That's why scratch builds still works (it's based in +the tarball content). + +As we're receiving some CVE's against slirp, we need a way to patch +slirp in RHEL-8.1.0 without handling as a separate package (as we do for +firmwares). + +The simplest solution is to copy the slirp folder from the tarball into the +exploded tree. + +To be able to do that, I had to make some changes: + +slirp needs to be removed from .gitmodules, otherwise git complains +about files on it. + +Since "make -C redhat rh-brew" uses the tarball and apply all the +patches on top of it, we need to remove the folder from the tarball before applying +the patch (because we are actually re-applying them). + +We also need to use --ignore-submodule while generating the patches for +scratch-build, otherwise it will include some weird definition of the +slirp folder in the patch, something that /usr/bin/patch gets mad with. + +After that I compared the patch list, after and before this change, and +saw no major differences. + +This is an exploded-tree-only change and shouldn't be applied to dist-git. + +Signed-off-by: Danilo C.

Created with contents that were learned at ++# the last time autoconf was run, and used by git-version-gen. Must not ++# be present in either $(srcdir) or $(builddir) for git-version-gen to ++# give accurate answers during normal development with a checked out tree, ++# but must be present in a tarball when there is no version control system. ++# Therefore, it cannot be used in any dependencies. GNUmakefile has ++# hooks to force a reconfigure at distribution time to get the value ++# correct, without penalizing normal development with extra reconfigures. ++# ++# .version - present in a checked-out repository and in a distribution ++# tarball. Usable in dependencies, particularly for files that don't ++# want to depend on config.h but do want to track version changes. ++# Delete this file prior to any autoconf run where you want to rebuild ++# files to pick up a version string change; and leave it stale to ++# minimize rebuild time after unrelated changes to configure sources. ++# ++# It is probably wise to add these two files to .gitignore, so that you ++# don't accidentally commit either generated file. ++# ++# Use the following line in your configure.ac, so that $(VERSION) will ++# automatically be up-to-date each time configure is run (and note that ++# since configure.ac no longer includes a version string, Makefile rules ++# should not depend on configure.ac for version updates). ++# ++# AC_INIT([GNU project], ++# m4_esyscmd([build-aux/git-version-gen .tarball-version]), ++# [bug-project@example]) ++# ++# Then use the following lines in your Makefile.am, so that .version ++# will be present for dependencies, and so that .tarball-version will ++# exist in distribution tarballs. ++# ++# BUILT_SOURCES = $(top_srcdir)/.version ++# $(top_srcdir)/.version: ++# echo $(VERSION) > $@-t && mv $@-t $@ ++# dist-hook: ++# echo $(VERSION) > $(distdir)/.tarball-version ++ ++case $# in ++ 1|2) ;; ++ *) echo 1>&2 "Usage: $0 \$srcdir/.tarball-version" \ ++ '[TAG-NORMALIZATION-SED-SCRIPT]' ++ exit 1;; ++esac ++ ++tarball_version_file=$1 ++tag_sed_script="${2:-s/x/x/}" ++nl=' ++' ++ ++# Avoid meddling by environment variable of the same name. ++v= ++ ++# First see if there is a tarball-only version file. ++# then try "git describe", then default. ++if test -f $tarball_version_file ++then ++ v=`cat $tarball_version_file` || exit 1 ++ case $v in ++ *$nl*) v= ;; # reject multi-line output ++ [0-9]*) ;; ++ *) v= ;; ++ esac ++ test -z "$v" \ ++ && echo "$0: WARNING: $tarball_version_file seems to be damaged" 1>&2 ++fi ++ ++if test -n "$v" ++then ++ : # use $v ++elif test -d .git \ ++ && v=`git describe --abbrev=4 --match='v*' HEAD 2>/dev/null \ ++ || git describe --abbrev=4 HEAD 2>/dev/null` \ ++ && v=`printf '%s\n' "$v" | sed "$tag_sed_script"` \ ++ && case $v in ++ v[0-9]*) ;; ++ *) (exit 1) ;; ++ esac ++then ++ # Is this a new git that lists number of commits since the last ++ # tag or the previous older version that did not? ++ # Newer: v6.10-77-g0f8faeb ++ # Older: v6.10-g0f8faeb ++ case $v in ++ *-*-*) : git describe is okay three part flavor ;; ++ *-*) ++ : git describe is older two part flavor ++ # Recreate the number of commits and rewrite such that the ++ # result is the same as if we were using the newer version ++ # of git describe. ++ vtag=`echo "$v" | sed 's/-.*//'` ++ numcommits=`git rev-list "$vtag"..HEAD | wc -l` ++ v=`echo "$v" | sed "s/\(.*\)-\(.*\)/\1-$numcommits-\2/"`; ++ ;; ++ esac ++ ++ # Change the first '-' to a '.', so version-comparing tools work properly. ++ # Remove the "g" in git describe's output string, to save a byte. ++ v=`echo "$v" | sed 's/-/./;s/\(.*\)-g/\1-/'`; ++else ++ v=UNKNOWN ++fi ++ ++v=`echo "$v" |sed 's/^v//'` ++ ++# Don't declare a version "dirty" merely because a time stamp has changed. ++git update-index --refresh > /dev/null 2>&1 ++ ++dirty=`sh -c 'git diff-index --name-only HEAD' 2>/dev/null` || dirty= ++case "$dirty" in ++ '') ;; ++ *) # Append the suffix only if there isn't one already. ++ case $v in ++ *-dirty) ;; ++ *) v="$v-dirty" ;; ++ esac ;; ++esac ++ ++# Omit the trailing newline, so that m4_esyscmd can use the result directly. ++echo "$v" | tr -d "$nl" ++ ++# Local variables: ++# eval: (add-hook 'write-file-hooks 'time-stamp) ++# time-stamp-start: "scriptversion=" ++# time-stamp-format: "%:y-%02m-%02d.%02H" ++# time-stamp-time-zone: "UTC" ++# time-stamp-end: "; # UTC" ++# End: +diff --git a/slirp/meson.build b/slirp/meson.build +new file mode 100644 +index 0000000000..cb1396ad59 +--- /dev/null ++++ b/slirp/meson.build +@@ -0,0 +1,162 @@ ++project('libslirp', 'c', ++ version : '4.6.1', ++ license : 'BSD-3-Clause', ++ default_options : ['warning_level=1', 'c_std=gnu99'], ++ meson_version : '>= 0.50', ++) ++ ++version = meson.project_version() ++varr = version.split('.') ++major_version = varr[0] ++minor_version = varr[1] ++micro_version = varr[2] ++ ++conf = configuration_data() ++conf.set('SLIRP_MAJOR_VERSION', major_version) ++conf.set('SLIRP_MINOR_VERSION', minor_version) ++conf.set('SLIRP_MICRO_VERSION', micro_version) ++ ++full_version = run_command('build-aux/git-version-gen', ++ '@0@/.tarball-version'.format(meson.current_source_dir()), ++ check : true).stdout().strip() ++if full_version.startswith('UNKNOWN') ++ full_version = meson.project_version() ++elif not full_version.startswith(meson.project_version()) ++ error('meson.build project version @0@ does not match git-describe output @1@' ++ .format(meson.project_version(), full_version)) ++endif ++conf.set_quoted('SLIRP_VERSION_STRING', full_version + get_option('version_suffix')) ++ ++# libtool versioning -

At the time the server -first started sending error messages, the assertion could not be -triggered, because messages were completely under our control. -However, over the years, we have added latent scenarios where a client -could trigger the server to attempt an error message that would -include the client's information if it passed other checks first: - -- requesting NBD_OPT_INFO/GO on an export name that is not present - (commit 0cfae925 in v2.12 echoes the name) - -- requesting NBD_OPT_LIST/SET_META_CONTEXT on an export name that is - not present (commit e7b1948d in v2.12 echoes the name) - -At the time, those were still safe because we flagged names larger -than 256 bytes with a different message; but that changed in commit -93676c88 (v4.2) when we raised the name limit to 4096 to match the NBD -string limit. (That commit also failed to change the magic number -4096 in nbd_negotiate_send_rep_err to the just-introduced named -constant.) So with that commit, long client names appended to server -text can now trigger the assertion, and thus be used as a denial of -service attack against a server. As a mitigating factor, if the -server requires TLS, the client cannot trigger the problematic paths -unless it first supplies TLS credentials, and such trusted clients are -less likely to try to intentionally crash the server. - -We may later want to further sanitize the user-supplied strings we -place into our error messages, such as scrubbing out control -characters, but that is less important to the CVE fix, so it can be a -later patch to the new nbd_sanitize_name. - -Consideration was given to changing the assertion in -nbd_negotiate_send_rep_verr to instead merely log a server error and -truncate the message, to avoid leaving a latent path that could -trigger a future CVE DoS on any new error message. However, this -merely complicates the code for something that is already (correctly) -flagging coding errors, and now that we are aware of the long message -pitfall, we are less likely to introduce such errors in the future, -which would make such error handling dead code. - -Reported-by: Xueqiang Wei -CC: qemu-stable@nongnu.org -Fixes: https://bugzilla.redhat.com/1843684 CVE-2020-10761 -Fixes: 93676c88d7 -Signed-off-by: Eric Blake -Message-Id: <20200610163741.3745251-2-eblake@redhat.com> -Reviewed-by: Vladimir Sementsov-Ogievskiy -(cherry picked from commit 5c4fe018c025740fef4a0a4421e8162db0c3eefd) -Signed-off-by: Eric Blake -Signed-off-by: Eduardo Lima (Etrunko) ---- - nbd/server.c | 23 ++++++++++++++++++++--- - tests/qemu-iotests/143 | 4 ++++ - tests/qemu-iotests/143.out | 2 ++ - 3 files changed, 26 insertions(+), 3 deletions(-) - -diff --git a/nbd/server.c b/nbd/server.c -index 24ebc1a805..d5b9df092c 100644 ---- a/nbd/server.c -+++ b/nbd/server.c -@@ -217,7 +217,7 @@ nbd_negotiate_send_rep_verr(NBDClient *client, uint32_t type, - - msg = g_strdup_vprintf(fmt, va); - len = strlen(msg); -- assert(len < 4096); -+ assert(len < NBD_MAX_STRING_SIZE); - trace_nbd_negotiate_send_rep_err(msg); - ret = nbd_negotiate_send_rep_len(client, type, len, errp); - if (ret < 0) { -@@ -231,6 +231,19 @@ nbd_negotiate_send_rep_verr(NBDClient *client, uint32_t type, - return 0; - } - -+/* -+ * Return a malloc'd copy of @name suitable for use in an error reply. -+ */ -+static char * -+nbd_sanitize_name(const char *name) -+{ -+ if (strnlen(name, 80) < 80) { -+ return g_strdup(name); -+ } -+ /* XXX Should we also try to sanitize any control characters? */ -+ return g_strdup_printf("%.80s...", name); -+} -+ - /* Send an error reply. - * Return -errno on error, 0 on success. */ - static int GCC_FMT_ATTR(4, 5) -@@ -595,9 +608,11 @@ static int nbd_negotiate_handle_info(NBDClient *client, Error **errp) - - exp = nbd_export_find(name); - if (!exp) { -+ g_autofree char *sane_name = nbd_sanitize_name(name); -+ - return nbd_negotiate_send_rep_err(client, NBD_REP_ERR_UNKNOWN, - errp, "export '%s' not present", -- name); -+ sane_name); - } - - /* Don't bother sending NBD_INFO_NAME unless client requested it */ -@@ -995,8 +1010,10 @@ static int nbd_negotiate_meta_queries(NBDClient *client, - - meta->exp = nbd_export_find(export_name); - if (meta->exp == NULL) { -+ g_autofree char *sane_name = nbd_sanitize_name(export_name); -+ - return nbd_opt_drop(client, NBD_REP_ERR_UNKNOWN, errp, -- "export '%s' not present", export_name); -+ "export '%s' not present", sane_name); - } - - ret = nbd_opt_read(client, &nb_queries, sizeof(nb_queries), errp); -diff --git a/tests/qemu-iotests/143 b/tests/qemu-iotests/143 -index f649b36195..d2349903b1 100755 ---- a/tests/qemu-iotests/143 -+++ b/tests/qemu-iotests/143 -@@ -58,6 +58,10 @@ _send_qemu_cmd $QEMU_HANDLE \ - $QEMU_IO_PROG -f raw -c quit \ - "nbd+unix:///no_such_export?socket=$SOCK_DIR/nbd" 2>&1 \ - | _filter_qemu_io | _filter_nbd -+# Likewise, with longest possible name permitted in NBD protocol -+$QEMU_IO_PROG -f raw -c quit \ -+ "nbd+unix:///$(printf %4096d 1 | tr ' ' a)?socket=$SOCK_DIR/nbd" 2>&1 \ -+ | _filter_qemu_io | _filter_nbd | sed 's/aaaa*aa/aa--aa/' - - _send_qemu_cmd $QEMU_HANDLE \ - "{ 'execute': 'quit' }" \ -diff --git a/tests/qemu-iotests/143.out b/tests/qemu-iotests/143.out -index 1f4001c601..fc9c0a761f 100644 ---- a/tests/qemu-iotests/143.out -+++ b/tests/qemu-iotests/143.out -@@ -5,6 +5,8 @@ QA output created by 143 - {"return": {}} - qemu-io: can't open device nbd+unix:///no_such_export?socket=SOCK_DIR/nbd: Requested export not available - server reported: export 'no_such_export' not present -+qemu-io: can't open device nbd+unix:///aa--aa1?socket=SOCK_DIR/nbd: Requested export not available -+server reported: export 'aa--aa...' not present - { 'execute': 'quit' } - {"return": {}} - {"timestamp": {"seconds": TIMESTAMP, "microseconds": TIMESTAMP}, "event": "SHUTDOWN", "data": {"guest": false, "reason": "host-qmp-quit"}} --- -2.27.0 - diff --git a/SOURCES/kvm-net-forbid-the-reentrant-RX.patch b/SOURCES/kvm-net-forbid-the-reentrant-RX.patch deleted file mode 100644 index aaf57ed..0000000 --- a/SOURCES/kvm-net-forbid-the-reentrant-RX.patch +++ /dev/null @@ -1,50 +0,0 @@ -From 1e01e2f96fd5e903394eab59365d5363394c8b18 Mon Sep 17 00:00:00 2001 -From: Jon Maloy -Date: Tue, 13 Apr 2021 18:59:12 -0400 -Subject: [PATCH 3/5] net: forbid the reentrant RX - -RH-Author: Jon Maloy -Message-id: <20210413185912.3811035-2-jmaloy@redhat.com> -Patchwork-id: 101467 -O-Subject: [RHEL-8.5.0 qemu-kvm PATCH 1/1] net: forbid the reentrant RX -Bugzilla: 1859175 -RH-Acked-by: Stefan Hajnoczi -RH-Acked-by: Thomas Huth -RH-Acked-by: Xiao Wang - -From: Jason Wang - -The memory API allows DMA into NIC's MMIO area.

In the case of a -complete machine emulation, eg. a sPAPR machine, an external interrupt -request could still be pending in KVM though, eg. an IPI. It will be -eventually presented to the guest, which is supposed to acknowledge it at -the interrupt controller. If the interrupt controller is emulated in QEMU, -either XICS or XIVE, ppc_set_irq() won't deassert the external interrupt -pin in KVM since it isn't pending anymore for QEMU. When the vCPU re-enters -the guest, the interrupt request is still pending and the vCPU will try -again to acknowledge it.

Report this value as an additional QMP field, present when -measuring an existing image and output format that both support -bitmaps. Update iotest 178 and 190 to updated output, as well as new -coverage in 190 demonstrating non-zero values made possible with the -recently-added qemu-img bitmap command (see 3b51ab4b). - -The new 'bitmaps size:' field is displayed automatically as part of -'qemu-img measure' any time it is present in QMP (that is, any time -both the source image being measured and destination format support -bitmaps, even if the measurement is 0 because there are no bitmaps -present). If the field is absent, it means that no bitmaps can be -copied (source, destination, or both lack bitmaps, including when -measuring based on size rather than on a source image). This behavior -is compatible with an upcoming patch adding 'qemu-img convert ---bitmaps': that command will fail in the same situations where this -patch omits the field. - -The addition of a new field demonstrates why we should always -zero-initialize qapi C structs; while the qcow2 driver still fully -populates all fields, the raw and crypto drivers had to be tweaked to -avoid uninitialized data. - -Consideration was also given towards having a 'qemu-img measure ---bitmaps' which errors out when bitmaps are not possible, and -otherwise sums the bitmaps into the existing allocation totals rather -than displaying as a separate field, as a potential convenience -factor. But this was ultimately decided to be more complexity than -necessary when the QMP interface was sufficient enough with bitmaps -remaining a separate field. - -See also: https://bugzilla.redhat.com/1779904 - -Reported-by: Nir Soffer -Signed-off-by: Eric Blake -Message-Id: <20200521192137.1120211-3-eblake@redhat.com> -Reviewed-by: Vladimir Sementsov-Ogievskiy -(cherry picked from commit 5d72c68b49769c927e90b78af6d90f6a384b26ac) - -Signed-off-by: Danilo C.

This is -correct from an implementation point of view, as we have modeled the -transition from non-secure to secure as a program directed IPL. From -a user perspective, this is not the behavior of least surprise. - -We should implement the IPL into protected mode similar to the -functions that we use for kdump/kexec. In other words, we do not stop -here when -no-reboot is specified on the command line. Like function 0 -or function 1, function 10 is not a classic reboot. For example, it -can only be called once.

So we need the notion of daemon doing -the locks which are visible to rest of the guests. - -Given posix locks are per process, one can not call posix lock API on host, -otherwise bunch of basic posix locks properties are broken. For example, -If two processes (A and B) in guest open the file and take locks on different -sections of file, if one of the processes closes the fd, it will close -fd on virtiofsd and all posix locks on file will go away. This means if -process A closes the fd, then locks of process B will go away too. - -Similar other problems exist too. - -This patch set tries to emulate posix locks while using open file -description locks provided on Linux. - -Daemon provides two options (-o posix_lock, -o no_posix_lock) to enable -or disable posix locking in daemon. By default it is enabled. - -There are few issues though. - -- GETLK() returns pid of process holding lock. As we are emulating locks - using OFD, and these locks are not per process and don't return pid - of process, so GETLK() in guest does not reuturn process pid. - -- As of now only F_SETLK is supported and not F_SETLKW. We can't block - the thread in virtiofsd for arbitrary long duration as there is only - one thread serving the queue. That means unlock request will not make - it to daemon and F_SETLKW will block infinitely and bring virtio-fs - to a halt. This is a solvable problem though and will require significant - changes in virtiofsd and kernel.

For the time being -only one worker thread is allowed since passthrough_ll.c is not -thread-safe yet. Future patches will lift this restriction so that -multiple FUSE requests can be processed in parallel. - -The main new concept is struct FVRequest, which contains both -VuVirtqElement and struct fuse_chan. We now have fv_VuDev for a device, -fv_QueueInfo for a virtqueue, and FVRequest for a request. Some of -fv_QueueInfo's fields are moved into FVRequest because they are -per-request. The name FVRequest conforms to QEMU coding style and I -expect the struct fv_* types will be renamed in a future refactoring. - -This patch series is not optimal. fbuf reuse is dropped so each request -does malloc(se->bufsize), but there is no clean and cheap way to keep -this with a thread pool. The vq_lock mutex is held for longer than -necessary, especially during the eventfd_write() syscall. Performance -can be improved in the future. - -prctl(2) had to be added to the seccomp whitelist because glib invokes -it. - -Signed-off-by: Stefan Hajnoczi -Reviewed-by: Misono Tomohiro -Signed-off-by: Dr. David Alan Gilbert -(cherry picked from commit a3d756c5aecccc4c0e51060a7e2f1c87bf8f1180) -Signed-off-by: Miroslav Rezanina ---- - tools/virtiofsd/fuse_virtio.c | 359 +++++++++++++++++++++++------------------- - 1 file changed, 201 insertions(+), 158 deletions(-) - -diff --git a/tools/virtiofsd/fuse_virtio.c b/tools/virtiofsd/fuse_virtio.c -index f6242f9..0dcf2ef 100644 ---- a/tools/virtiofsd/fuse_virtio.c -+++ b/tools/virtiofsd/fuse_virtio.c -@@ -22,6 +22,7 @@ - - #include - #include -+#include - #include - #include - #include -@@ -37,17 +38,28 @@ - struct fv_VuDev;
