l2tp: convert l2tp_tunnel_list to idr
[ Upstream commit
c4d48a58f32c5972174a1d01c33b296fe378cce0 ]
l2tp uses l2tp_tunnel_list to track all registered tunnels and
to allocate tunnel ID's. IDR can do the same job.
More importantly, with IDR we can hold the ID before a successful
registration so that we don't need to worry about late error
handling, it is not easy to rollback socket changes.
This is a preparation for the following fix.

net/sched: sch_taprio: fix possible use-after-free
[ Upstream commit
3a415d59c1dbec9d772dbfab2d2520d98360caae ]
syzbot reported a nasty crash [1] in net_tx_action() which
made little sense until we got a repro.
This repro installs a taprio qdisc, but providing an
invalid TCA_RATE attribute.
qdisc_create() has to destroy the just initialized
taprio qdisc, and taprio_destroy() is called.
However, the hrtimer used by taprio had already fired,
therefore advance_sched() called __netif_schedule().
Then net_tx_action was trying to use a destroyed qdisc.
We can not undo the __netif_schedule(), so we must wait
until one cpu serviced the qdisc before we can proceed.
Many thanks to Alexander Potapenko for his help.

net: stmmac: Fix queue statistics reading

Correct queue statistics reading. All queue statistics are stored as unsigned
long values. The retrieval for ethtool fetches these values as u64. However, on
some systems the size of the counters are 32 bit. That yields wrong queue
statistic counters e.g., on arm32 systems such as the stm32mp157. Fix it by
using the correct data type.

Fix this by adding support for RK3568 in rockchip_get_pull, including a

sch_htb: Avoid grafting on htb_destroy_class_offload when destroying htb
[ Upstream commit
a22b7388d658ecfcd226600c8c34ce4481e88655 ]
Peek at old qdisc and graft only when deleting a leaf class in the htb,
rather than when deleting the htb itself. Do not peek at the qdisc of the
netdev queue when destroying the htb. The caller may already have grafted a
new qdisc that is not part of the htb structure being destroyed.
This fix resolves two use cases.
1. Using tc to destroy the htb.
- Netdev was being prematurely activated before the htb was fully
destroyed.
2. Using tc to replace the htb with another qdisc (which also leads to
the htb being destroyed).
- Premature netdev activation like previous case. Newly grafted qdisc
was also getting accidentally overwritten when destroying the htb.

an interrupt, and the NET_TX softirq then gets scheduled, this will take
the netif_tx_lock() a second time and deadlock the kernel.
To solve this, use netif_tx_lock_bh(), which blocks softirqs from
running.

net: nfc: Fix use-after-free in local_cleanup()
[ Upstream commit
4bb4db7f3187c6e3de6b229ffc87cdb30a2d22b6 ]
Fix a use-after-free that occurs in kfree_skb() called from
local_cleanup(). This could happen when killing nfc daemon (e.g. neard)
after detaching an nfc device.
When detaching an nfc device, local_cleanup() called from
nfc_llcp_unregister_device() frees local->rx_pending and decreases
local->ref by kref_put() in nfc_llcp_local_put().
In the terminating process, nfc daemon releases all sockets and it leads
to decreasing local->ref. After the last release of local->ref,
local_cleanup() called from local_release() frees local->rx_pending
again, which leads to the bug.
Setting local->rx_pending to NULL in local_cleanup() could prevent
use-after-free when local_cleanup() is called twice.
Found by a modified version of syzkaller.

bpf: Fix pointer-leak due to insufficient speculative store bypass mitigation
[ Upstream commit
e4f4db47794c9f474b184ee1418f42e6a07412b6 ]
To mitigate Spectre v4,
2039f26f3aca ("bpf: Fix leakage due to
insufficient speculative store bypass mitigation") inserts lfence
instructions after 1) initializing a stack slot and 2) spilling a
pointer to the stack.
However, this does not cover cases where a stack slot is first
initialized with a pointer (subject to sanitization) but then
overwritten with a scalar (not subject to sanitization because
the slot was already initialized). In this case, the second write
may be subject to speculative store bypass (SSB) creating a
speculative pointer-as-scalar type confusion. This allows the
program to subsequently leak the numerical pointer value using,
for example, a branch-based cache side channel.
To fix this, also sanitize scalars if they write a stack slot
that previously contained a pointer. Assuming that pointer-spills
are only generated by LLVM on register-pressure, the performance
impact on most real-world BPF programs should be small.
The following unprivileged BPF bytecode drafts a minimal exploit
and the mitigation:
[...]
// r6 = 0 or 1 (skalar, unknown user input)
// r7 = accessible ptr for side channel
// r10 = frame pointer (fp), to be leaked
//
r9 = r10 # fp alias to encourage ssb
*(u64 *)(r9 - 8) = r10 // fp[-8] = ptr, to be leaked
// lfence added here because of pointer spill to stack.
//
// Ommitted: Dummy bpf_ringbuf_output() here to train alias predictor
// for no r9-r10 dependency.
//
*(u64 *)(r10 - 8) = r6 // fp[-8] = scalar, overwrites ptr
//
2039f26f3aca: no lfence added because stack slot was not STACK_INVALID,
// store may be subject to SSB
//
// fix: also add an lfence when the slot contained a ptr
//
r8 = *(u64 *)(r9 - 8)
// r8 = architecturally a scalar, speculatively a ptr
//
// leak ptr using branch-based cache side channel:
r8 &= 1 // choose bit to leak
if r8 == 0 goto SLOW // no mispredict
// architecturally dead code if input r6 is 0,
// only executes speculatively iff ptr bit is 1
r8 = *(u64 *)(r7 + 0) # encode bit in cache (0: slow, 1: fast)
SLOW:
[...]
After running this, the program can time the access to *(r7 + 0) to
determine whether the chosen pointer bit was 0 or 1. Repeat this 64
times to recover the whole address on amd64.
In summary, sanitization can only be skipped if one scalar is
overwritten with another scalar. Scalar-confusion due to speculative
store bypass can not lead to invalid accesses because the pointer
bounds deducted during verification are enforced using branchless
logic. See
979d63d50c0c ("bpf: prevent out of bounds speculation on
pointer arithmetic") for details.
Do not make the mitigation depend on !env->allow_{uninit_stack,ptr_leaks}
because speculative leaks are likely unexpected if these were enabled.
For example, leaking the address to a protected log file may be acceptable
while disabling the mitigation might unintentionally leak the address
into the cached-state of a map that is accessible to unprivileged
processes.

The deadlock still may occur while accessed in NMI and non-NMI

For example, on the same CPU, .max_entries = 2, we update the hash map,
with key = 4, while running bpf prog in NMI nmi_handle(), to update
hash map with key = 20, so it will have the same bucket index but have

among other functions, vc4_create_object() to use drmm_mutex_init().
However, that function is used to allocate a BO, and therefore the
mutex needs to be freed much sooner than when the DRM device is removed
from the system.
For each buffer allocation we thus end up allocating a small structure
as part of the DRM-managed mechanism that is never freed, eventually
leading us to no longer having any free memory anymore.
Let's switch back to mutex_init/mutex_destroy to deal with it properly.

[ Upstream commit
8debed3efe3a731451ad9a91a7a74eeb18a7f7eb ]
Nathan Chancellor reports that $(NM) emits an error message when
GNU Make 4.4 is used to build the ARM zImage.
$ make-4.4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=build defconfig zImage

GZIP arch/arm/boot/compressed/piggy_data

This occurs since GNU Make commit
98da874c4303 ("[SV 10593] Export
variables to $(shell ...) commands"), and the O= option is needed to
reproduce it. The generated zImage is correct despite the error message.
As the commit description of
98da874c4303 [1] says, exported variables
are passed down to $(shell ) functions, which means exported recursive
variables might be expanded earlier than before, in the parse stage.
The following test code demonstrates the change for GNU Make 4.4.
[Test Makefile]
$(shell echo hello > foo)
export foo = $(shell cat bar/../foo)
$(shell mkdir bar)
all:
@echo $(foo)
[GNU Make 4.3]
$ rm -rf bar; make-4.3
hello
[GNU Make 4.4]
$ rm -rf bar; make-4.4
cat: bar/../foo: No such file or directory
hello
The 'foo' is a resursively expanded (i.e. lazily expanded) variable.
GNU Make 4.3 expands 'foo' just before running the recipe '@echo $(foo)',
at this point, the directory 'bar' exists.
GNU Make 4.4 expands 'foo' to evaluate $(shell mkdir bar) because it is
exported. At this point, the directory 'bar' does not exit yet. The cat
command cannot resolve the bar/../foo path, hence the error message.
Let's get back to the kernel Makefile.
In arch/arm/boot/compressed/Makefile, KBSS_SZ is referenced by
LDFLAGS_vmlinux, which is recursive and also exported by the top
Makefile.
GNU Make 4.3 expands KBSS_SZ just before running the recipes, so no
error message.
GNU Make 4.4 expands KBSS_SZ in the parse stage, where the directory
arm/arm/boot/compressed does not exit yet. When compiled with O=,
the output directory is created by $(shell mkdir -p $(obj-dirs))
in scripts/Makefile.build.
There are two ways to fix this particular issue:
- change "$(obj)/../../../../vmlinux" in KBSS_SZ to "vmlinux"
- unexport LDFLAGS_vmlinux
This commit takes the latter course because it is what I originally
intended.
Commit
3ec8a5b33dea ("kbuild: do not export LDFLAGS_vmlinux")
unexported LDFLAGS_vmlinux.
Commit
5d4aeffbf709 ("kbuild: rebuild .vmlinux.export.o when its

We can clean up arch/arm/boot/compressed/Makefile later.

During setup, there is a possible race between a page invalidate

target range during setup. If anything within that range is
invalidated during setup, fail the setup. Once set up, each
TID will have its own invalidate callback and invalidate.

RDMA/core: Fix ib block iterator counter overflow
[ Upstream commit
0afec5e9cea732cb47014655685a2a47fb180c31 ]
When registering a new DMA MR after selecting the best aligned page size
for it, we iterate over the given sglist to split each entry to smaller,
aligned to the selected page size, DMA blocks.
In given circumstances where the sg entry and page size fit certain
sizes and the sg entry is not aligned to the selected page size, the
total size of the aligned pages we need to cover the sg entry is >= 4GB.
Under this circumstances, while iterating page aligned blocks, the
counter responsible for counting how much we advanced from the start of
the sg entry is overflowed because its type is u32 and we pass 4GB in
size. This can lead to an infinite loop inside the iterator function
because the overflow prevents the counter to be larger
than the size of the sg entry.
Fix the presented problem by changing the advancement condition to
eliminate overflow.

ef86b2c2807f41c045e5534d8513a8b83f63bc39 ]
On newer Tegra releases, early boot SID override programming and SID
override programming during resume is handled by bootloader.
In the function tegra186_mc_program_sid() which is getting removed, SID
override register of all clients is written without checking if secure
firmware has allowed write on it or not. If write is disabled by secure
firmware then it can lead to errors coming from secure firmware and hang
in kernel boot.
Also, SID override is programmed on-demand during probe_finalize() call
of IOMMU which is done in tegra186_mc_client_sid_override() in this same
file. This function does it correctly by checking if write is permitted
on SID override register. It also checks if SID override register is
already written with correct value and skips re-writing it in that case.

octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rt

The commit
4af1b64f80fb ("octeontx2-pf: Fix lmtst ID used in aura

in ->aura_freeptr() callback, but it also unnecessarily disable the
preemption for the blockable memory allocation. The commit
87b93b678e95
("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to
fix these sleep inside atomic warnings. But it only fix the one for
the non-rt kernel. For the rt kernel, we still get the similar warnings
like below.

Of course, we can shuffle the get/put_cpu() to only wrap the invocation
of ->aura_freeptr() as what commit
87b93b678e95 does. But there are only
two ->aura_freeptr() callbacks, otx2_aura_freeptr() and
cn10k_aura_freeptr(). There is no usage of perpcu variable in the
otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it.
We can move the get/put_cpu() into the corresponding callback which
really has the percpu variable usage and avoid the sprinkling of
get/put_cpu() in several places.

net/ulp: use consistent error code when blocking ULP
commit
8ccc99362b60c6f27bb46f36fdaaccf4ef0303de upstream.
The referenced commit changed the error code returned by the kernel
when preventing a non-established socket from attaching the ktls
ULP. Before to such a commit, the user-space got ENOTCONN instead
of EINVAL.
The existing self-tests depend on such error code, and the change
caused a failure:
RUN global.non_established ...
tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107)
non_established: Test failed at step #3
FAIL global.non_established
In the unlikely event existing applications do the same, address
the issue by restoring the prior error code in the above scenario.
Note that the only other ULP performing similar checks at init
time - smc_ulp_ops - also fails with ENOTCONN when trying to attach
the ULP to a non-established socket.
