commit e901b9873876ca30a09253731bd3a6b00c44b5b0 upstream.

This patch adds a new helper function to perform a sanity check of the given URB to see whether it contains a valid endpoint. It's a light- weight version of what usb_submit_urb() does, but without the kernel warning followed by the stack trace, just returns an error code.

Especially for a driver that doesn't parse the descriptor but fills the URB with the fixed endpoint (e.g. some quirks for non-compliant devices), this kind of check is preferable at the probe phase before actually submitting the urb.

commit e5571240236c5652f3e079b1d5866716a7ad819c upstream.

This is needed to prevent sk_user_data being overwritten. The check is done under the callback lock. This should prevent a socket from being attached twice to a KCM mux. It also prevents a socket from being attached for other use cases of sk_user_data as long as the other cases set sk_user_data under the lock. Followup work is needed to unify all the use cases of sk_user_data to use the same locking.

commit 6f16101e6a8b4324c36e58a29d9e0dbb287cdedb upstream.

syzkaller generated a BPF proglet and triggered a warning with the following:

0: (b7) r0 = 0 1: (d5) if r0 s<= 0x0 goto pc+0 R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0 2: (1f) r0 -= r1 R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0 verifier internal error: known but bad sbounds

What happens is that in the first insn, r0's min/max value are both 0 due to the immediate assignment, later in the jsle test the bounds are updated for the min value in the false path, meaning, they yield smin_val = 1, smax_val = 0, and when ctx pointer is subtracted from r0, verifier bails out with the internal error and throwing a WARN since smin_val != smax_val for the known constant.

For min_val > max_val scenario it means that reg_set_min_max() and reg_set_min_max_inv() (which both refine existing bounds) demonstrated that such branch cannot be taken at runtime.

In above scenario for the case where it will be taken, the existing [0, 0] bounds are kept intact. Meaning, the rejection is not due to a verifier internal error, and therefore the WARN() is not necessary either.

We could just reject such cases in adjust_{ptr,scalar}_min_max_vals() when either known scalars have smin_val != smax_val or umin_val != umax_val or any scalar reg with bounds smin_val > smax_val or umin_val > umax_val. However, there may be a small risk of breakage of buggy programs, so handle this more gracefully and in adjust_{ptr,scalar}_min_max_vals() just taint the dst reg as unknown scalar when we see ops with such kind of src reg.

commit 51a1aaa631c90223888d8beac4d649dc11d2ca55 upstream.

When creating a new radio on the fly, hwsim allows this to be done with an arbitrary number of channels, but cfg80211 only supports a limited number of simultaneous channels, leading to a warning.

Fix this by validating the number - this requires moving the define for the maximum out to a visible header file.

commit b1bdcb59b64f806ef08d25a85c39ffb3ad841ce6 upstream.

xfrm_policy_cache_flush can sleep, so it cannot be called while holding a spinlock. We could release the lock first, but I don't see why we need to invoke this function here in first place, the packet path won't reuse an xdst entry unless its still valid.

While at it, add an annotation to xfrm_policy_cache_flush, it would have probably caught this bug sooner.

syzkaller triggered following KASAN splat:

in xfrm_policy_walk() via pfkey (it sets tiny rcv space, dump callback returns -ENOBUFS).

In this case, *walk is located the pfkey socket struct, so this socket becomes visible in the global policy list.

It looks like this is intentional -- phony walker has walk.dead set to 1 and all other places skip such "policies".

Ccing original authors of the two commits that seem to expose this issue (first patch missed ->dead check, second patch adds pfkey sockets to policies dumper list).

commit d0e312fe3d34c1bc014a7f8ec6540d05e8077483 upstream.

The RDMA netlink core code checks validity of messages by ensuring that type and operand are in range. It works well for almost all clients except NLDEV, which has cb_table less than number of operands.

Request to access such operand will trigger the following kernel panic.

This patch updates all places where cb_table is declared for the consistency, but only NLDEV is actually need it.

From: Cong Wang xiyou.wangcong@gmail.com

commit 6a53b7593233ab9e4f96873ebacc0f653a55c3e1 upstream.

syzbot reported a kernel warning in xfrm_state_fini(), which indicates that we have entries left in the list net->xfrm.state_all whose proto is zero. And xfrm_id_proto_match() doesn't consider them as a match with IPSEC_PROTO_ANY in this case.

Proto with value 0 is probably not a valid value, at least verify_newsa_info() doesn't consider it valid either.

This patch fixes it by checking the proto value in validate_tmpl() and rejecting invalid ones, like what iproute2 does in xfrm_xfrmproto_getbyname().

commit a6da0024ffc19e0d47712bb5ca4fd083f76b07df upstream.

We need to ensure that tracepoints are registered and unregistered with the users of them. The existing atomic count isn't enough for that. Add a lock around the tracepoints, so we serialize access to them.

This fixes cases where we have multiple users setting up and tearing down tracepoints, like this:

commit 4b14752ec4e0d87126e636384cf37c8dd9df157c upstream.

We can't do anything reasonable in security_bounded_transition() if we don't have a policy loaded, and in fact we could run into problems with some of the code inside expecting a policy. Fix these problems like we do many others in security/selinux/ss/services.c by checking to see if the policy is loaded (ss_initialized) and returning quickly if it isn't.

Using %rbp as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code.

In twofish-3way, we can't simply replace %rbp with another register because there are none available. Instead, we use the stack to hold the values that %rbp, %r11, and %r12 were holding previously. Each of these values represents the half of the output from the previous Feistel round that is being passed on unchanged to the following round. They are only used once per round, when they are exchanged with %rax, %rbx, and %rcx.

As a result, we free up 3 registers (one per block) and can reassign them so that %rbp is not used, and additionally %r14 and %r15 are not used so they do not need to be saved/restored.

There may be a small overhead caused by replacing 'xchg REG, REG' with the needed sequence 'mov MEM, REG; mov REG, MEM; mov REG, REG' once per round. But, counterintuitively, when I tested "ctr-twofish-3way" on a Haswell processor, the new version was actually about 2% faster. (Perhaps 'xchg' is not as well optimized as plain moves.)

commit e4e179a844f52e907e550f887d0a2171f1508af1 upstream.

Syzbot reported a warning with Ion:

WARNING: CPU: 0 PID: 3502 at drivers/staging/android/ion/ion-ioctl.c:73 ion_ioctl+0x2db/0x380 drivers/staging/android/ion/ion-ioctl.c:73 Kernel panic - not syncing: panic_on_warn set ...

This is a warning that validation of the ioctl fields failed. This was deliberately added as a warning to make it very obvious to developers that something needed to be fixed. In reality, this is overkill and disturbs fuzzing. Switch to pr_warn for a message instead.

commit a77660d231f8b3d84fd23ed482e0964f7aa546d6 upstream.

Currently KCOV_ENABLE does not check if the current task is already associated with another kcov descriptor. As the result it is possible to associate a single task with more than one kcov descriptor, which later leads to a memory leak of the old descriptor. This relation is really meant to be one-to-one (task has only one back link).

Extend validation to detect such misuse.

commit da17c73b6eb74aad3c3c0654394635675b623b3e upstream.

It looks like syzbot found its way into netfilter territory.

Issue here is that @name comes from user space and might not be null terminated.

Out-of-bound reads happen, KASAN is not happy.

v2 added similar fix for xt_request_find_target(), as Florian advised.

commit 3f34cfae1238848fd53f25e5c8fd59da57901f4b upstream.

Syzbot reported several deadlocks in the netfilter area caused by rtnl lock and socket lock being acquired with a different order on different code paths, leading to backtraces like the following one:

====================================================== WARNING: possible circular locking dependency detected 4.15.0-rc9+ #212 Not tainted ------------------------------------------------------ syzkaller041579/3682 is trying to acquire lock: (sk_lock-AF_INET6){+.+.}, at: [<000000008775e4dd>] lock_sock include/net/sock.h:1463 [inline] (sk_lock-AF_INET6){+.+.}, at: [<000000008775e4dd>] do_ipv6_setsockopt.isra.8+0x3c5/0x39d0 net/ipv6/ipv6_sockglue.c:167

which lock already depends on the new lock.

the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Possible unsafe locking scenario:

*** DEADLOCK ***

The problem, as Florian noted, is that nf_setsockopt() is always called with the socket held, even if the lock itself is required only for very tight scopes and only for some operation.

This patch addresses the issues moving the lock_sock() call only where really needed, namely in ipv*_getorigdst(), so that nf_setsockopt() does not need anymore to acquire both locks.

commit 7dc68e98757a8eccf8ca7a53a29b896f1eef1f76 upstream.

rateest_hash is supposed to be protected by xt_rateest_mutex, and, as suggested by Eric, lookup and insert should be atomic, so we should acquire the xt_rateest_mutex once for both.

So introduce a non-locking helper for internal use and keep the locking one for external.

commit f10b4cff98c6977668434fbf5dd58695eeca2897 upstream.

The rds_tcp_kill_sock() function parses the rds_tcp_conn_list to find the rds_connection entries marked for deletion as part of the netns deletion under the protection of the rds_tcp_conn_lock. Since the rds_tcp_conn_list tracks rds_tcp_connections (which have a 1:1 mapping with rds_conn_path), multiple tc entries in the rds_tcp_conn_list will map to a single rds_connection, and will be deleted as part of the rds_conn_destroy() operation that is done outside the rds_tcp_conn_lock.

The rds_tcp_conn_list traversal done under the protection of rds_tcp_conn_lock should not leave any doomed tc entries in the list after the rds_tcp_conn_lock is released, else another concurrently executiong netns delete (for a differnt netns) thread may trip on these entries.

commit 40ca54e3a686f13117f3de0c443f8026dadf7c44 upstream.

syzbot reported a lockdep splat in gen_new_estimator() / est_fetch_counters() when attempting to lock est->stats_lock.

Since est_fetch_counters() is called from BH context from timer interrupt, we need to block BH as well when calling it from process context.

Most qdiscs use per cpu counters and are immune to the problem, but net/sched/act_api.c and net/netfilter/xt_RATEEST.c are using a spinlock to protect their data. They both call gen_new_estimator() while object is created and not yet alive, so this bug could not trigger a deadlock, only a lockdep splat.

From: Todd Kjos tkjos@android.com

commit e46a3b3ba7509cb7fda0e07bc7c63a2cd90f579b upstream.

binder_send_failed_reply() is called when a synchronous transaction fails. It reports an error to the thread that is waiting for the completion. Given that the transaction is synchronous, there should never be more than 1 error response to that thread -- this was being asserted with a WARN().

However, when exercising the driver with syzbot tests, cases were observed where multiple "synchronous" requests were sent without waiting for responses, so it is possible that multiple errors would be reported to the thread. This testing was conducted with panic_on_warn set which forced the crash.

This is easily reproduced by sending back-to-back "synchronous" transactions without checking for any response (eg, set read_size to 0):

bwr.write_buffer = (uintptr_t)&bc1; bwr.write_size = sizeof(bc1); bwr.read_buffer = (uintptr_t)&br; bwr.read_size = 0; ioctl(fd, BINDER_WRITE_READ, &bwr); sleep(1); bwr2.write_buffer = (uintptr_t)&bc2; bwr2.write_size = sizeof(bc2); bwr2.read_buffer = (uintptr_t)&br; bwr2.read_size = 0; ioctl(fd, BINDER_WRITE_READ, &bwr2); sleep(1);

The first transaction is sent to the servicemanager and the reply fails because no VMA is set up by this client. After binder_send_failed_reply() is called, the BINDER_WORK_RETURN_ERROR is sitting on the thread's todo list since the read_size was 0 and the client is not waiting for a response.

The 2nd transaction is sent and the BINDER_WORK_RETURN_ERROR has not been consumed, so the thread's reply_error.cmd is still set (normally cleared when the BINDER_WORK_RETURN_ERROR is handled). Therefore when the servicemanager attempts to reply to the 2nd failed transaction, the error is already set and it triggers this warning.

This is a user error since it is not waiting for the synchronous transaction to complete. If it ever does check, it will see an error.

Changed the WARN() to a pr_warn().

The external clock frequency was set only when selecting the internal clock, which is fixed at 4.9152 Mhz.

This is incorrect, since it should be set when any of the external clock or crystal settings is selected.

Added range validation for the external (crystal/clock) frequency setting. Valid values are between 2.4576 and 5.12 Mhz.

The receive_buf callback is supposed to return the number of bytes processed and should specifically not return a negative errno.

Due to missing sanity checks in the serdev tty-port controller, a driver not providing a receive_buf callback could cause the flush_to_ldisc() worker to spin in a tight loop when the tty buffer pointers are incremented with -EINVAL (-22).

The missing sanity checks have now been added to the tty-port controller, but let's fix up the serdev-controller helper as well.

[ Upstream commit 59622fd496a3175c7bf549046e091d81c303ecff ]

The Intel PMU event aliases have a implicit period= specifier to set the default period.

Unfortunately this breaks overriding these periods with -c or -F, because the alias terms look like they are user specified to the internal parser, and user specified event qualifiers override the command line options.

Track that they are coming from aliases by adding a "weak" state to the term. Any weak terms don't override command line options.

I only did it for -c/-F for now, I think that's the only case that's broken currently.

Before:

$ perf record -c 1000 -vv -e uops_issued.any ... { sample_period, sample_freq } 2000003

After:

$ perf record -c 1000 -vv -e uops_issued.any ... { sample_period, sample_freq } 1000

There are many instructions, esp on PowerPC, whose mnemonics are longer than 6 characters. Using precision limit causes truncation of such mnemonics.

Fix this by removing precision limit. Note that, 'width' is still 6, so alignment won't get affected for length <= 6.

I've noticed the following message while booting a S905X based board:

soc soc0: Amlogic Meson GXL (S905D) Revision 21:82 (b:2) Detected

The S905D string is obviously wrong. The vendor code does: ... ver = (readl(assist_hw_rev) >> 8) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_MINOR] = ver; ver = (readl(assist_hw_rev) >> 16) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_PACK] = ver; ...

while the current code does: ... ...

This means that the current mainline code has package id and minor version reversed.

Currently there is only one sdbuf per Control QP (CQP) for programming Segment Descriptor (SD). If multiple SD work requests are posted simultaneously, the sdbuf is reused by all WQEs and new WQEs can corrupt previous WQEs sdbuf leading to incorrect SD programming.

Fix this by allocating one sdbuf per CQP SQ WQE. When an SD command is posted, it will use the corresponding sdbuf for the WQE.

Now outstanding_bytes is only increased when appending chunks into one packet and sending it at 1st time, while decreased when it is about to move into retransmit queue. It means outstanding_bytes value is already decreased for all chunks in retransmit queue.

However sctp_prsctp_prune_sent is a common function to check the chunks in both transmitted and retransmit queue, it decrease outstanding_bytes when moving a chunk into abandoned queue from either of them.

It could cause outstanding_bytes underflow, as it also decreases it's value for the chunks in retransmit queue.

This patch fixes it by only updating outstanding_bytes for transmitted queue when pruning queues for prsctp prio policy, the same fix is also needed in sctp_check_transmitted.

My bisect scripts starting running into build failures when trying to compile 4.15-rc1 with the builds failing with things like:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:2078: error: Cannot parse struct or union!

The line in question is actually just a #define, but after some digging it turns out that my scripts pass W=1 and since commit 3a025e1d1c2ea ("Add optional check for bad kernel-doc comments") that results in kernel-doc running on each source file. The file in question has a badly formatted comment immediately before the #define:

/** * struct brcmf_skbuff_cb reserves first two bytes in sk_buff::cb for * bus layer usage. */

which causes the regex in dump_struct to fail (lack of braces following struct declaration) and kernel-doc returns 1, which causes the build to fail.

Fix the issue by always returning 0 from kernel-doc when invoked with -none. It successfully generates no documentation, and prints out any issues.

[ Upstream commit 58117672943734715bbe7565ac9f062effa524f0 ]

According to LS1021A RM, the value of PAL can be set so that the start of the IP header in the receive data buffer is aligned to a 32-bit boundary. Normally, setting PAL = 2 provides minimal padding to ensure such alignment of the IP header.

However every incoming packet's 8-byte time stamp will be inserted into the packet data buffer as padding alignment bytes when hardware time stamping is enabled.

So we set the padding 8+2 here to avoid the flooded alignment faults:

[ Upstream commit b430b7751286b3acff2d324553c8cec4f1e87764 ]

Commit c6887cd11149 ("Btrfs: don't do nocow check unless we have to") changed the behavior of __btrfs_buffered_write() so that it first tries to get a data space reservation, and then skips the relatively expensive nocow check if the reservation succeeded.

If we have quotas enabled, the data space reservation also includes a quota reservation. But in the rewrite case, the space has already been accounted for in qgroups. So btrfs_check_data_free_space() increases the quota reservation, but it never gets decreased when the data actually gets written and overwrites the pre-existing data. So we're left with both the qgroup and qgroup reservation accounting for the same space.

This commit adds the missing btrfs_qgroup_free_data() call in the case of BTRFS_ORDERED_PREALLOC extents.

From: Nikolay Borisov nborisov@suse.com

[ Upstream commit c8bcbfbd239ed60a6562964b58034ac8a25f4c31 ]

The name char array passed to btrfs_search_path_in_tree is of size BTRFS_INO_LOOKUP_PATH_MAX (4080). So the actual accessible char indexes are in the range of [0, 4079]. Currently the code uses the define but this represents an off-by-one.

Implications:

Size of btrfs_ioctl_ino_lookup_args is 4096, so the new byte will be written to extra space, not some padding that could be provided by the allocator.

btrfs-progs store the arguments on stack, but kernel does own copy of the ioctl buffer and the off-by-one overwrite does not affect userspace, but the ending 0 might be lost.

Kernel ioctl buffer is allocated dynamically so we're overwriting somebody else's memory, and the ioctl is privileged if args.objectid is not 256. Which is in most cases, but resolving a subvolume stored in another directory will trigger that path.

Before this patch the buffer was one byte larger, but then the -1 was not added.

[ Upstream commit 3d5fdba1842bdd2eef29364c660558cb4cbb3fe0 ]

When removing the interrupt handling code, we should mask the generation of interrupts. The code however unmasked all interrupts. This can then cause a new interrupt. We then get into a deadlock where the interrupt thread is waiting to run, and the code continues, trying to remove the interrupt handler, which means waiting for the thread to complete. On a UP machine this deadlocks.

Fix so we really mask interrupts in the hardware. The same error is made in the error path when install the interrupt handling code.

In some cases the clock parent would be set NULL when doing re-parent, it will cause a NULL pointer accessing if clk_set trace event is enabled.

Mistakenly the driver didn't allow RSS hash fields combinations which involve both IPv4 and IPv6 protocols. This bug caused to failures for user's use cases for RSS.

Consequently, this patch fixes this bug and allows any combination that the HW can support.

Additionally, the patch fixes the driver to return an error in case the user provides an unsupported mask for RSS hash fields.

Oops is observed during boot:

Faulting instruction address: 0xc000000000248340 cpu 0x0: Vector: 380 (Data Access Out of Range) at [c000000ff66fb850] pc: c000000000248340: event_function_call+0x50/0x1f0 lr: c00000000024878c: perf_remove_from_context+0x3c/0x100 sp: c000000ff66fbad0 msr: 9000000000009033 dar: 7d20e2a6f92d03c0 pid = 14, comm = cpuhp/0

While registering the cpuhotplug callbacks for nest-imc, if we fail in the cpuhotplug online path for any random node in a multi node system (because the opal call to stop nest-imc counters fails for that node), ppc_nest_imc_cpu_offline() will get invoked for other nodes who successfully returned from cpuhotplug online path.

This call trace is generated since in the ppc_nest_imc_cpu_offline() path we are trying to migrate the event context, when nest-imc counters are not even initialized.

Patch to add a check to ensure that nest-imc is registered before migrating the event context.

This patch fixes that Oops by checking if src is NULL.

commit c927b080c67e3e97193c81fc1d27f4251bf4e036 upstream.

In AES-ECB mode crypt is done with key only, so any use of IV can cause kernel Oops. Use IV only in AES-CBC and AES-CTR.
