The recent expansion of the sched switch tracepoint inserted a new argument
in the middle of the arguments. This reordering broke BPF programs which relied on the old argument list. While tracepoints are not considered stable ABI, it's not trivial to make BPF cope with such a change, but it's being worked on. For now restore the original argument order and move the new argument to the end of the argument list. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmKAxKQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoThID/4jp/8GiKsf1jPgKkU39Yw7qAePzObQ V9K2XLxSwH27D+UpmOPODnckzHJMtX0M4Z+sGMgGSPe/IvOVj+NEmUiQGU29sDwg T7If2FSHMutPCB9QL26kxjmebU+SdllRwrJylOA1ZNduunczxKlpATJ5vneCC/Qt D5VpB3XlwT31pd9UdoW/kV5uQK6bFR7qREWXhONZ+HyzsKJdV0vGe2ZX6U7ek2/d XJxETE1eXlsMr+2VY5lkxhr596uPJgDAM9g+OknO/Lal/I7WoUchDN2giItzn6RY XWxPK85mE59MwTa6PQCJcO8A7r2KcHfGrbFVjA9h1jhREtsZigb9ZemDgQ+s8goT znIIlTO2l7ed2VDMU/mt3zZuS0rMshn/8Axk+AN3N6gKffV6F4q0BpZUUccGe+FM tfQ34YGmMKx6uuyHPPZCQd1buJuDuXNyZF7XFO3uxv9BGt3x42aswAbx1zYIV+ZR Uj/Vnojoc1aBdffVSUL0he+vjutYixx4gb8nh0ZFa5FTe70XDvPGTUTTOSW6BOq0 yiFOWtG8MbziVBDE2iKmfUMT+dPQd0+PW8szk8J9yOJyOnTu9y6KkyWl2JRllSxT Qv7icnMN5P1xqN/c4P+8Iq0CrVItyxMJ0Ouc29tsNPHYkzsBo4c0XAn94mib1O17 zyJYW0F9UVHOSg== =6Bvx -----END PGP SIGNATURE----- Merge tag 'sched-urgent-2022-05-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fix from Thomas Gleixner: "The recent expansion of the sched switch tracepoint inserted a new argument in the middle of the arguments.

Bluetooth: Fix the creation of hdev->name
Set a size limit of 8 bytes of the written buffer to "hdev->name" including the terminating null byte, as the size of "hdev->name" is 8 bytes. If an id value which is greater than 9999 is allocated, then the "snprintf(hdev->name, sizeof(hdev->name), "hci%d", id)" function call would lead to a truncation of the id value in decimal notation. Set an explicit maximum id parameter in the id allocation function call. The id allocation function defines the maximum allocated id value as the maximum id parameter value minus one. Therefore, HCI_MAX_ID is defined as 10000. Signed-off-by: Itay Iellin <ieitayie@gmail.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> |

net/sched: act_pedit: really ensure the skb is writable
Currently pedit tries to ensure that the accessed skb offset
is writable via skb_unclone(). The action potentially allows
touching any skb bytes, so it may end-up modifying shared data.
The above causes some sporadic MPTCP self-test failures, due to
this code:
tc -n $ns2 filter add dev ns2eth$i egress \
protocol ip prio 1000 \
handle 42 fw \
action pedit munge offset 148 u8 invert \
pipe csum tcp \
index 100
The above modifies a data byte outside the skb head and the skb is
a cloned one, carrying a TCP output packet.
This change addresses the issue by keeping track of a rough
over-estimate highest skb offset accessed by the action and ensuring
such offset is really writable.
Note that this may cause performance regressions in some scenarios,
but hopefully pedit is not in the critical path.

filter->trap_list. This is in addition to their normal placement on the
VCAP block->rules list head.
Therefore, when we free a VCAP filter, we must remove it from all lists
it is a member of, including ocelot->traps.
There are at least 2 bugs which are direct consequences of this design
decision.
First is the incorrect usage of list_empty(), meant to denote whether
"filter" is chained into ocelot->traps via filter->trap_list.
This does not do the correct thing, because list_empty() checks whether
"head->next == head", but in our case, head->next == head->prev == NULL.
So we dereference NULL pointers and die when we call list_del().
Second is the fact that not all places that should remove the filter
from ocelot->traps do so. One example is ocelot_vcap_block_remove_filter(),
which is where we have the main kfree(filter). By keeping freed filters
in ocelot->traps we end up in a use-after-free in
felix_update_trapping_destinations().
Attempting to fix all the buggy patterns is a whack-a-mole game which
makes the driver unmaintainable. Actually this is what the previous
patch version attempted to do:
https://patchwork.kernel.org/project/netdevbpf/patch/20220503115728.834457-3-vladimir.oltean@nxp.com/
but it introduced another set of bugs, because there are other places in
which create VCAP filters, not just ocelot_vcap_filter_create():
- ocelot_trap_add()
- felix_tag_8021q_vlan_add_rx()
- felix_tag_8021q_vlan_add_tx()
Relying on the convention that all those code paths must call
INIT_LIST_HEAD(&filter->trap_list) is not going to scale.
So let's do what should have been done in the first place and keep a
bool in struct ocelot_vcap_filter which denotes whether we are looking
at a trapping rule or not. Iterating now happens over the main VCAP IS2
block->rules. The advantage is that we no longer risk having stale
references to a freed filter, since it is only present in that list.

net: Fix features skip in for_each_netdev_feature()
The find_next_netdev_feature() macro gets the "remaining length",
not bit index.
Passing "bit - 1" for the following iteration is wrong as it skips
the adjacent bit. Pass "bit" instead.

Two folio fixes for 5.18:
- Fix a race when we were calling folio_next() in the BIO folio iter
without holding a reference, meaning the folio could be split or freed,
and we'd jump to the next page instead of the intended next folio.
- Fix readahead creating single-page folios instead of the intended
large folios when doing reads that are not a power of two in size.

block: Do not call folio_next() on an unreferenced folio
It is unsafe to call folio_next() on a folio unless you hold a reference on it that prevents it from being split or freed. After returning from the iterator, iomap calls folio_end_writeback() which may drop the last reference to the page, or allow the page to be split. If that happens, the iterator will not advance far enough through the bio_vec, leading to assertion failures like the BUG() in folio_end_writeback() that checks we're not trying to end writeback on a page not currently under writeback. Other assertion failures were also seen, but they're all explained by this one bug. Fix the bug by remembering where the next folio starts before returning from the iterator. There are other ways of fixing this bug, but this seems the simplest. Reported-by: Darrick J. Wong <djwong@kernel.org> Tested-by: Darrick J.

net: stmmac: disable Split Header (SPH) for Intel platforms
Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation
of Split Header (SPH) feature is not supported for Ipv4 fragmented packet.
This SPH limitation will cause ping failure when the packets size exceed
the MTU size. For example, the issue happens once the basic ping packet
size is larger than the configured MTU size and the data is lost inside
the fragmented packet, replaced by zeros/corrupted values, and leads to
ping fail.
So, disable the Split Header for Intel platforms.
v2: Add fixes tag in commit message.
Fixes: 67afd6d1cfdf("net: stmmac: Add Split Header support and enable it in XGMAC cores")

A semi-large pile of clk driver fixes this time around. Nothing is
touching the core so these fixes are fairly well contained to specific
devices that use these clk drivers.
- Some Allwinner SoC fixes to gracefully handle errors and mark an RTC
clk as critical so that the RTC keeps ticking.
- Fix AXI bus clks and RTC clk design for Microchip PolarFire SoC
driver introduced this cycle. This has some devicetree bits acked by
riscv maintainers. We're fixing it now so that the prior bindings
aren't released in a major kernel version.
- Remove a reset on Microchip PolarFire SoCs that broke when enabling
CONFIG_PM.
- Set a min/max for the Qualcomm graphics clk. This got broken by the
clk rate range patches introduced this cycle.

KVM: fix bad user ABI for KVM_EXIT_SYSTEM_EVENT
When KVM_EXIT_SYSTEM_EVENT was introduced, it included a flags member that at the time was unused. Unfortunately this extensibility mechanism has several issues: - x86 is not writing the member, so it would not be possible to use it on x86 except for new events - the member is not aligned to 64 bits, so the definition of the uAPI struct is incorrect for 32- on 64-bit userspace. This is a problem for RISC-V, which supports CONFIG_KVM_COMPAT, but fortunately usage of flags was only introduced in 5.18. Since padding has to be introduced, place a new field in there that tells if the flags field is valid. To allow further extensibility, in fact, change flags to an array of 16 values, and store how many of the values are valid. The availability of the new ndata field is tied to a system capability; all architectures are changed to fill in the field. To avoid breaking compilation of userspace that was using the flags field, provide a userspace-only union to overlap flags with data[0]. The new field is placed at the same offset for both 32- and 64-bit userspace.

SUNRPC: Ensure gss-proxy connects on setup
For reasons best known to the author, gss-proxy does not implement a
NULL procedure, and returns RPC_PROC_UNAVAIL. However we still want to
ensure that we connect to the service at setup time.
So add a quirk-flag specially for this case.

elf: Fix the arm64 MTE ELF segment name and value
Unfortunately, the name/value choice for the MTE ELF segment type
(PT_ARM_MEMTAG_MTE) was pretty poor: LOPROC+1 is already in use by
PT_AARCH64_UNWIND, as defined in the AArch64 ELF ABI
(https://github.com/ARM-software/abi-aa/blob/main/aaelf64/aaelf64.rst).
Update the ELF segment type value to LOPROC+2 and also change the define
to PT_AARCH64_MEMTAG_MTE to match the AArch64 ELF ABI namespace. The
AArch64 ELF ABI document is updating accordingly (segment type not
previously mentioned in the document).

hex2bin: make the function hex_to_bin constant-time
The function hex2bin is used to load cryptographic keys into device mapper targets dm-crypt and dm-integrity. It should take constant time independent on the processed data, so that concurrently running unprivileged code can't infer any information about the keys via microarchitectural convert channels. This patch changes the function hex_to_bin so that it contains no branches and no memory accesses. Note that this shouldn't cause performance degradation because the size of the new function is the same as the size of the old function (on x86-64) - and the new function causes no branch misprediction penalties. I compile-tested this function with gcc on aarch64 alpha arm hppa hppa64 i386 ia64 m68k mips32 mips64 powerpc powerpc64 riscv sh4 s390x sparc32 sparc64 x86_64 and with clang on aarch64 arm hexagon i386 mips32 mips64 powerpc powerpc64 s390x sparc32 sparc64 x86_64 to verify that there are no branches in the generated code.

net: Use this_cpu_inc() to increment net->core_stats
The macro dev_core_stats_##FIELD##_inc() disables preemption and invokes netdev_core_stats_alloc() to return a per-CPU pointer. netdev_core_stats_alloc() will allocate memory on its first invocation which breaks on PREEMPT_RT because it requires non-atomic context for memory allocation. This can be avoided by enabling preemption in netdev_core_stats_alloc() assuming the caller always disables preemption. It might be better to replace local_inc() with this_cpu_inc() now that dev_core_stats_##FIELD##_inc() gained a preempt-disable section and does not rely on already disabled preemption.

xsk: Fix possible crash when multiple sockets are created
Fix a crash that happens if an Rx only socket is created first, then a
second socket is created that is Tx only and bound to the same umem as
the first socket and also the same netdev and queue_id together with the
XDP_SHARED_UMEM flag. In this specific case, the tx_descs array page
pool was not created by the first socket as it was an Rx only socket.
When the second socket is bound it needs this tx_descs array of this
shared page pool as it has a Tx component, but unfortunately it was
never allocated, leading to a crash. Note that this array is only used
for zero-copy drivers using the batched Tx APIs, currently only ice and
i40e.

Detect such case during bind() and allocate this memory region via newly
introduced xp_alloc_tx_descs(). Also, use kvcalloc instead of kcalloc as
for other buffer pool allocations, so that it matches the kvfree() from
xp_destroy().

bug: Have __warn() prototype defined unconditionally
The __warn() prototype is declared in CONFIG_BUG scope but the function
definition in panic.c is unconditional. The IBT enablement started using
it unconditionally but a CONFIG_X86_KERNEL_IBT=y, CONFIG_BUG=n .config
will trigger a
arch/x86/kernel/traps.c: In function ‘__exc_control_protection’:
arch/x86/kernel/traps.c:249:17: error: implicit declaration of function \
‘__warn’; did you mean ‘pr_warn’? [-Werror=implicit-function-declaration]
Pull up the declarations so that they're unconditionally visible too.

tcp: make sure treq->af_specific is initialized
syzbot complained about a recent change in TCP stack,
hitting a NULL pointer [1]
tcp request sockets have an af_specific pointer, which
was used before the blamed change only for SYNACK generation
in non SYNCOOKIE mode.
tcp requests sockets momentarily created when third packet
coming from client in SYNCOOKIE mode were not using
treq->af_specific.
Make sure this field is populated, in the same way normal
TCP requests sockets do in tcp_conn_request().

ip_gre, ip6_gre: Fix race condition on o_seqno in collect_md mode
As pointed out by Jakub Kicinski, currently using TUNNEL_SEQ in collect_md mode is racy for [IP6]GRE[TAP] devices. Consider the following sequence of events: 1. An [IP6]GRE[TAP] device is created in collect_md mode using "ip link add ... external". "ip" ignores "[o]seq" if "external" is specified, so TUNNEL_SEQ is off, and the device is marked as NETIF_F_LLTX (i.e. it uses lockless TX); 2. Someone sets TUNNEL_SEQ on outgoing skb's, using e.g. bpf_skb_set_tunnel_key() in an eBPF program attached to this device; 3. gre_fb_xmit() or __gre6_xmit() processes these skb's: gre_build_header(skb, tun_hlen, flags, protocol, tunnel_id_to_key32(tun_info->key.tun_id), (flags & TUNNEL_SEQ) ? htonl(tunnel->o_seqno++) : 0); ^^^^^^^^^^^^^^^^^ Since we are not using the TX lock (&txq->_xmit_lock), multiple CPUs may try to do this tunnel->o_seqno++ in parallel, which is racy. Fix it by making o_seqno atomic_t. As mentioned by Eric Dumazet in commit |
