x86/speculation: Add RSB VM Exit protections
commit 2b1299322016731d56807aa49254a5ea3080b6b3 upstream.
tl;dr: The Enhanced IBRS mitigation for Spectre v2 does not work as
documented for RET instructions after VM exits. Mitigate it with a new
one-entry RSB stuffing mechanism and a new LFENCE.
== Background ==
Indirect Branch Restricted Speculation (IBRS) was designed to help
mitigate Branch Target Injection and Speculative Store Bypass, i.e.
Spectre, attacks. IBRS prevents software run in less privileged modes
from affecting branch prediction in more privileged modes. IBRS requires
the MSR to be written on every privilege level change.
To overcome some of the performance issues of IBRS, Enhanced IBRS was
introduced. eIBRS is an "always on" IBRS, in other words, just turn
it on once instead of writing the MSR on every privilege level change.
When eIBRS is enabled, more privileged modes should be protected from
less privileged modes, including protecting VMMs from guests.
== Problem ==
Here's a simplification of how guests are run on Linux' KVM:
void run_kvm_guest(void)
{
// Prepare to run guest
VMRESUME();
// Clean up after guest runs
}
The execution flow for that would look something like this to the
processor:
1. Host-side: call run_kvm_guest()
2. Host-side: VMRESUME
3. Guest runs, does "CALL guest_function"
4. VM exit, host runs again
5. Host might make some "cleanup" function calls
6. Host-side: RET from run_kvm_guest()
Now, when back on the host, there are a couple of possible scenarios of
post-guest activity the host needs to do before executing host code:
* on pre-eIBRS hardware (legacy IBRS, or nothing at all), the RSB is not
touched and Linux has to do a 32-entry stuffing.
* on eIBRS hardware, VM exit with IBRS enabled, or restoring the host
IBRS=1 shortly after VM exit, has a documented side effect of flushing
the RSB except in this PBRSB situation where the software needs to stuff
the last RSB entry "by hand".
IOW, with eIBRS supported, host RET instructions should no longer be
influenced by guest behavior after the host retires a single CALL
instruction.
However, if the RET instructions are "unbalanced" with CALLs after a VM
exit as is the RET in #6, it might speculatively use the address for the
instruction after the CALL in #3 as an RSB prediction. This is a problem
since the (untrusted) guest controls this address.
Balanced CALL/RET instruction pairs such as in step #5 are not affected.
== Solution ==
The PBRSB issue affects a wide variety of Intel processors which
support eIBRS. But not all of them need mitigation. Today,
X86_FEATURE_RSB_VMEXIT triggers an RSB filling sequence that mitigates
PBRSB. Systems setting RSB_VMEXIT need no further mitigation - i.e.,
eIBRS systems which enable legacy IBRS explicitly.
However, such systems (X86_FEATURE_IBRS_ENHANCED) do not set RSB_VMEXIT
and most of them need a new mitigation.
Therefore, introduce a new feature flag X86_FEATURE_RSB_VMEXIT_LITE
which triggers a lighter-weight PBRSB mitigation versus RSB_VMEXIT.
The lighter-weight mitigation performs a CALL instruction which is
immediately followed by a speculative execution barrier (INT3). This
steers speculative execution to the barrier -- just like a retpoline
-- which ensures that speculation can never reach an unbalanced RET.
Then, ensure this CALL is retired before continuing execution with an
LFENCE.
In other words, the window of exposure is opened at VM exit where RET
behavior is troublesome. While the window is open, force RSB predictions
sampling for RET targets to a dead end at the INT3. Close the window
with the LFENCE.
There is a subset of eIBRS systems which are not vulnerable to PBRSB.
Add these systems to the cpu_vuln_whitelist[] as NO_EIBRS_PBRSB.
Future systems that aren't vulnerable will set ARCH_CAP_PBRSB_NO.

UPSTREAM: wireguard: selftests: set fake real time in init
commit 829be057dbc1e71383b8d7de8edb31dcf07b4aa0 upstream. Not all platforms have an RTC, and rather than trying to force one into each, it's much easier to just set a fixed time. This is necessary because WireGuard's latest handshakes parameter is returned in wallclock time, and if the system time isn't set, and the system is really fast, then this returns 0, which trips the test. Turning this on requires setting CONFIG_COMPAT_32BIT_TIME=y, as musl doesn't support settimeofday without it. Signed-off-by: Jason A.

commit ca93ca23409b827b48a2fc0a692496d3f7b67944 upstream. The seed_rng() function was written to work across lots of old kernels, back when WireGuard used a big compatibility layer. Now that things have evolved, we can vastly simplify this, by just marking the RNG as seeded. Signed-off-by: Jason A.

UPSTREAM: wireguard: device: reset peer src endpoint when netns exits
commit 20ae1d6aa159eb91a9bf09ff92ccaa94dbea92c2 upstream.
Each peer's endpoint contains a dst_cache entry that takes a reference
to another netdev. When the containing namespace exits, we take down the
socket and prevent future sockets from being created (by setting
creating_net to NULL), which removes that potential reference on the
netns. However, it doesn't release references to the netns that a netdev
cached in dst_cache might be taking, so the netns still might fail to
exit. Since the socket is gimped anyway, we can simply clear all the
dst_caches (by way of clearing the endpoint src), which will release all
references.
However, the current dst_cache_reset function only releases those
references lazily. But it turns out that all of our usages of
wg_socket_clear_peer_endpoint_src are called from contexts that are not
exactly high-speed or bottle-necked. For example, when there's
connection difficulty, or when userspace is reconfiguring the interface.
And in particular for this patch, when the netns is exiting. So for
those cases, it makes more sense to call dst_release immediately. For
that, we add a small helper function to dst_cache.
This patch also adds a test to netns.sh from Hangbin Liu to ensure this
doesn't regress.

UPSTREAM: wireguard: selftests: actually test for routing loops
commit 782c72af567fc2ef09bd7615d0307f24de72c7e0 upstream.
We previously removed the restriction on looping to self, and then added
a test to make sure the kernel didn't blow up during a routing loop. The
kernel didn't blow up, thankfully, but on certain architectures where
skb fragmentation is easier, such as ppc64, the skbs weren't actually
being discarded after a few rounds through. But the test wasn't catching
this. So actually test explicitly for massive increases in tx to see if
we have a routing loop. Note that the actual loop problem will need to
be addressed in a different commit.

UPSTREAM: wireguard: selftests: increase default dmesg log size
commit 03ff1b1def73f817e196bf96ab36ac259490bd7c upstream.
The selftests currently parse the kernel log at the end to track
potential memory leaks. With these tests now reading off the end of the
buffer, due to recent optimizations, some creation messages were lost,
making the tests think that there was a free without an alloc. Fix this
by increasing the kernel log size.

commit d5a49aa6c3e264a93a7d08485d66e346be0969dd upstream.
In order to test ndo_start_xmit being called in parallel, explicitly add
separate tests, which should all run on different cores. This should
help tease out bugs associated with queueing up packets from different
cores in parallel. Currently, it hasn't found those types of bugs, but
given future planned work, this is a useful regression to avoid.

commit af8afcf1fdd5f365f70e2386c2d8c7a1abd853d7 upstream. If netfilter changes the packet mark, the packet is rerouted. The ip_route_me_harder family of functions fails to use the right sk, opting to instead use skb->sk, resulting in a routing loop when used with tunnels. With the next change fixing this issue in netfilter, test for the relevant condition inside our test suite, since wireguard was where the bug was discovered.

commit 72b2aa38191bcba28389b0e20bf6b4f15017ff2b upstream.
The iio_utils uses a digit calculation in order to know length of the
file name containing a buffer number. The digit calculation does not
work for number 0.
This leads to allocation of one character too small buffer for the
file-name when file name contains value '0'. (Eg. buffer0).
Fix digit calculation by returning one digit to be present for number
'0'.

perf intel-pt: Fix segfault in intel_pt_print_info() with uClibc
commit 5a3d47071f0ced0431ef82a5fb6bd077ed9493db upstream.
uClibc segfaulted because NULL was passed as the format to fprintf().
That happened because one of the format strings was missing and
intel_pt_print_info() didn't check that before calling fprintf().
Add the missing format string, and check format is not NULL before calling
fprintf().

bpftool: Fix a wrong type cast in btf_dumper_int
[ Upstream commit 7184aef9c0f7a81db8fd18d183ee42481d89bf35 ]
When `data` points to a boolean value, casting it to `int *` is problematic
and could lead to a wrong value being passed to `jsonw_bool`. Change the
cast to `bool *` instead.

perf kcore_copy: Do not check /proc/modules is unchanged
[ Upstream commit 5b427df27b94aec1312cace48a746782a0925c53 ]
/proc/kallsyms and /proc/modules are compared before and after the copy
in order to ensure no changes during the copy.
However /proc/modules also might change due to reference counts changing
even though that does not make any difference.
Any modules loaded or unloaded should be visible in changes to kallsyms,
so it is not necessary to check /proc/modules also anyway.
Remove the comparison checking that /proc/modules is unchanged.

selftests/bpf: Fix test_align verifier log patterns
commit 5366d2269139ba8eb6a906d73a0819947e3e4e0a upstream.
Commit 294f2fc6da27 ("bpf: Verifer, adjust_scalar_min_max_vals to always
call update_reg_bounds()") changed the way verifier logs some of its state,
adjust the test_align accordingly. Where possible, I tried to not copy-paste
the entire log line and resorted to dropping the last closing brace instead.

bpf: Fix the off-by-two error in range markings
commit 2fa7d94afc1afbb4d702760c058dc2d7ed30f226 upstream.
The first commit cited below attempts to fix the off-by-one error that
appeared in some comparisons with an open range. Due to this error,
arithmetically equivalent pieces of code could get different verdicts
from the verifier, for example (pseudocode):
// 1. Passes the verifier:
if (data + 8 > data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
// 2. Rejected by the verifier (should still pass):
if (data + 7 >= data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
The attempted fix, however, shifts the range by one in a wrong
direction, so the bug not only remains, but also such piece of code
starts failing in the verifier:
// 3. Rejected by the verifier, but the check is stricter than in #1.
if (data + 8 >= data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
The change performed by that fix converted an off-by-one bug into
off-by-two. The second commit cited below added the BPF selftests
written to ensure than code chunks like #3 are rejected, however,
they should be accepted.
This commit fixes the off-by-two error by adjusting new_range in the
right direction and fixes the tests by changing the range into the
one that should actually fail.

tools build: Switch to new openssl API for test-libcrypto
commit 5b245985a6de5ac18b5088c37068816d413fb8ed upstream.
Switch to new EVP API for detecting libcrypto, as Fedora 36 returns an
error when it encounters the deprecated function MD5_Init() and the others.
The error would be interpreted as missing libcrypto, while in reality it is
not.

tools/thermal: Fix possible path truncations
[ Upstream commit 6c58cf40e3a1d2f47c09d3489857e9476316788a ]
A build with -D_FORTIFY_SOURCE=2 enabled will produce the following warnings:
sysfs.c:63:30: warning: '%s' directive output may be truncated writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-truncation=]
snprintf(filepath, 256, "%s/%s", path, filename);
^~
Bump up the buffer to PATH_MAX which is the limit and account for all of
the possible NUL and separators that could lead to exceeding the
allocated buffer sizes.

HAVE_LIBCRYPTO_SUPPORT, which is the define the feature test for openssl
defines, fix it.
This also adds disables the deprecation warning, someone has to fix this

BPF map name is limited to BPF_OBJ_NAME_LEN.
A map name is defined as being longer than BPF_OBJ_NAME_LEN,
it will be truncated to BPF_OBJ_NAME_LEN when a userspace program
calls libbpf to create the map. A pinned map also generates a path
in the /sys. If the previous program wanted to reuse the map，
it can not get bpf_map by name, because the name of the map is only
partially the same as the name which get from pinned path.
The syscall information below show that map name "process_pinned_map"
is truncated to "process_pinned_".
bpf(BPF_OBJ_GET, {pathname="/sys/fs/bpf/process_pinned_map",
bpf_fd=0, file_flags=0}, 144) = -1 ENOENT (No such file or directory)
bpf(BPF_MAP_CREATE, {map_type=BPF_MAP_TYPE_HASH, key_size=4,
value_size=4,max_entries=1024, map_flags=0, inner_map_fd=0,
map_name="process_pinned_",map_ifindex=0, btf_fd=3, btf_key_type_id=6,
btf_value_type_id=10,btf_vmlinux_value_type_id=0}, 72) = 4
This patch check that if the name of pinned map are the same as the
actual name for the first (BPF_OBJ_NAME_LEN - 1),
bpf map still uses the name which is included in bpf object.
