+Subject: i2c: designware: use casting of u64 in clock multiplication to avoid

+
+From: Lareine Khawaly <lareine@amazon.com>
+
+[ Upstream commit c8c37bc514514999e62a17e95160ed9ebf75ca8d ]
+
+In functions i2c_dw_scl_lcnt() and i2c_dw_scl_hcnt() may have overflow
+by depending on the values of the given parameters including the ic_clk.
+For example in our use case where ic_clk is larger than one million,
+multiplication of ic_clk * 4700 will result in 32 bit overflow.
+
+Add cast of u64 to the calculation to avoid multiplication overflow, and
+use the corresponding define for divide.

+
+Once a socket has been unhashed, we want to prevent it from being
+re-used in a sk_key entry as part of a routing operation.
+
+This change marks the sk as SOCK_DEAD on unhash, which prevents addition
+into the net's key list.
+
+We need to do this during the key add path, rather than key lookup, as
+we release the net keys_lock between those operations.

+From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
+
+[ Upstream commit c2b6cdee1d13ffbb24baca3c9b8a572d6b541e4e ]
+
+After system entered Suspend to RAM, registers setting of this
+hardware is reset because the SoC will be turned off. On R-Car Gen3
+(info->ccc_gac), ravb_ptp_init() is called in ravb_probe() only. So,
+after system resumed, it lacks of the initial settings for ptp. So,
+add ravb_ptp_{init,stop}() into ravb_{resume,suspend}().

+
+Code inspection shows that both tg3_io_error_detected() and
+tg3_reset_task() attempt to acquire the RTNL lock at the beginning of
+their code blocks. If tg3_reset_task() should happen to execute between
+the times when tg3_io_error_deteced() acquires the RTNL lock and
+tg3_reset_task_cancel() is called, a deadlock will occur.
+
+Moving tg3_reset_task_cancel() call earlier within the code block, prior
+to acquiring RTNL, prevents this from happening, but also exposes another
+deadlock issue where tg3_reset_task() may execute AFTER
+tg3_io_error_detected() has executed:

+Subject: netfilter: conntrack: fix vtag checks for ABORT/SHUTDOWN_COMPLETE
+
+From: Sriram Yagnaraman <sriram.yagnaraman@est.tech>
+
+[ Upstream commit a9993591fa94246b16b444eea55d84c54608282a ]
+
+RFC 9260, Sec 8.5.1 states that for ABORT/SHUTDOWN_COMPLETE, the chunk
+MUST be accepted if the vtag of the packet matches its own tag and the
+T bit is not set OR if it is set to its peer's vtag and the T bit is set
+in chunk flags. Otherwise the packet MUST be silently dropped.
+
+Update vtag verification for ABORT/SHUTDOWN_COMPLETE based on the above
+description.

+Subject: netfilter: nft_set_rbtree: Switch to node list walk for overlap
+ detection
+
+From: Pablo Neira Ayuso <pablo@netfilter.org>
+
+[ Upstream commit c9e6978e2725a7d4b6cd23b2facd3f11422c0643 ]
+
+...instead of a tree descent, which became overly complicated in an
+attempt to cover cases where expired or inactive elements would affect
+comparisons with the new element being inserted.
+
+Further, it turned out that it's probably impossible to cover all those
+cases, as inactive nodes might entirely hide subtrees consisting of a
+complete interval plus a node that makes the current insertion not
+overlap.
+
+To speed up the overlap check, descent the tree to find a greater
+element that is closer to the key value to insert. Then walk down the
+node list for overlap detection. Starting the overlap check from
+rb_first() unconditionally is slow, it takes 10 times longer due to the
+full linear traversal of the list.
+
+Moreover, perform garbage collection of expired elements when walking
+down the node list to avoid bogus overlap reports.
+
+For the insertion operation itself, this essentially reverts back to the
+implementation before commit 7c84d41416d8 ("netfilter: nft_set_rbtree:
+Detect partial overlaps on insertion"), except that cases of complete
+overlap are already handled in the overlap detection phase itself, which
+slightly simplifies the loop to find the insertion point.
+
+Based on initial patch from Stefano Brivio, including text from the
+original patch description too.

+Subject: netlink: prevent potential spectre v1 gadgets
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit f0950402e8c76e7dcb08563f1b4e8000fbc62455 ]
+
+Most netlink attributes are parsed and validated from
+__nla_validate_parse() or validate_nla()
+
+ u16 type = nla_type(nla);
+
+ if (type == 0 || type > maxtype) {
+ /* error or continue */
+ }
+
+@type is then used as an array index and can be used
+as a Spectre v1 gadget.
+
+array_index_nospec() can be used to prevent leaking
+content of kernel memory to malicious users.
+
+This should take care of vast majority of netlink uses,
+but an audit is needed to take care of others where
+validation is not yet centralized in core netlink functions.

+Subject: netrom: Fix use-after-free of a listening socket.
+
+From: Kuniyuki Iwashima <kuniyu@amazon.com>
+
+[ Upstream commit 409db27e3a2eb5e8ef7226ca33be33361b3ed1c9 ]
+
+syzbot reported a use-after-free in do_accept(), precisely nr_accept()
+as sk_prot_alloc() allocated the memory and sock_put() frees it. [0]
+
+The issue could happen if the heartbeat timer is fired and
+nr_heartbeat_expiry() calls nr_destroy_socket(), where a socket
+has SOCK_DESTROY or a listening socket has SOCK_DEAD.
+
+In this case, the first condition cannot be true. SOCK_DESTROY is
+flagged in nr_release() only when the file descriptor is close()d,
+but accept() is being called for the listening socket, so the second
+condition must be true.
+
+Usually, the AF_NETROM listener neither starts timers nor sets
+SOCK_DEAD. However, the condition is met if connect() fails before
+listen(). connect() starts the t1 timer and heartbeat timer, and
+t1timer calls nr_disconnect() when timeout happens. Then, SOCK_DEAD
+is set, and if we call listen(), the heartbeat timer calls
+nr_destroy_socket().
+
+ nr_connect
+ nr_establish_data_link(sk)
+ nr_start_t1timer(sk)
+ nr_start_heartbeat(sk)
+ nr_t1timer_expiry
+ nr_disconnect(sk, ETIMEDOUT)
+ nr_sk(sk)->state = NR_STATE_0
+ sk->sk_state = TCP_CLOSE
+ sock_set_flag(sk, SOCK_DEAD)
+nr_listen
+ if (sk->sk_state != TCP_LISTEN)
+ sk->sk_state = TCP_LISTEN
+ nr_heartbeat_expiry
+ switch (nr->state)
+ case NR_STATE_0
+ if (sk->sk_state == TCP_LISTEN &&
+ sock_flag(sk, SOCK_DEAD))
+ nr_destroy_socket(sk)
+
+This path seems expected, and nr_destroy_socket() is called to clean
+up resources. Initially, there was sock_hold() before nr_destroy_socket()
+so that the socket would not be freed, but the commit 517a16b1a88b
+("netrom: Decrease sock refcount when sock timers expire") accidentally
+removed it.
+
+To fix use-after-free, let's add sock_hold().

+Subject: scsi: ufs: core: Fix devfreq deadlocks
+
+From: Johan Hovold <johan+linaro@kernel.org>
+
+[ Upstream commit ba81043753fffbc2ad6e0c5ff2659f12ac2f46b4 ]
+
+There is a lock inversion and rwsem read-lock recursion in the devfreq
+target callback which can lead to deadlocks.
+
+Specifically, ufshcd_devfreq_scale() already holds a clk_scaling_lock
+read lock when toggling the write booster, which involves taking the
+dev_cmd mutex before taking another clk_scaling_lock read lock.
+
+This can lead to a deadlock if another thread:
+
+ 1) tries to acquire the dev_cmd and clk_scaling locks in the correct
+ order, or
+
+ 2) takes a clk_scaling write lock before the attempt to take the
+ clk_scaling read lock a second time.
+
+Fix this by dropping the clk_scaling_lock before toggling the write booster
+as was done before commit 0e9d4ca43ba8 ("scsi: ufs: Protect some contexts
+from unexpected clock scaling").
+
+While the devfreq callbacks are already serialised, add a second
+serialising mutex to handle the unlikely case where a callback triggered
+through the devfreq sysfs interface is racing with a request to disable
+clock scaling through the UFS controller 'clkscale_enable' sysfs
+attribute. This could otherwise lead to the write booster being left
+disabled after having disabled clock scaling.
+
+Also take the new mutex in ufshcd_clk_scaling_allow() to make sure that any
+pending write booster update has completed on return.
+
+Note that this currently only affects Qualcomm platforms since commit
+87bd05016a64 ("scsi: ufs: core: Allow host driver to disable wb toggling
+during clock scaling").
+
+The lock inversion (i.e. 1 above) was reported by lockdep as:

+Subject: sctp: fail if no bound addresses can be used for a given scope
+
+From: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com>
+
+[ Upstream commit 458e279f861d3f61796894cd158b780765a1569f ]
+
+Currently, if you bind the socket to something like:
+ servaddr.sin6_family = AF_INET6;
+ servaddr.sin6_port = htons(0);
+ servaddr.sin6_scope_id = 0;
+ inet_pton(AF_INET6, "::1", &servaddr.sin6_addr);
+
+And then request a connect to:
+ connaddr.sin6_family = AF_INET6;
+ connaddr.sin6_port = htons(20000);
+ connaddr.sin6_scope_id = if_nametoindex("lo");
+ inet_pton(AF_INET6, "fe88::1", &connaddr.sin6_addr);
+
+What the stack does is:
+ - bind the socket
+ - create a new asoc
+ - to handle the connect
+ - copy the addresses that can be used for the given scope
+ - try to connect
+
+But the copy returns 0 addresses, and the effect is that it ends up
+trying to connect as if the socket wasn't bound, which is not the
+desired behavior. This unexpected behavior also allows KASLR leaks
+through SCTP diag interface.
+
+The fix here then is, if when trying to copy the addresses that can
+be used for the scope used in connect() it returns 0 addresses, bail
+out. This is what TCP does with a similar reproducer.

+Subject: tools: gpio: fix -c option of gpio-event-mon
+
+From: Ivo Borisov Shopov <ivoshopov@gmail.com>
+
+[ Upstream commit 677d85e1a1ee69fa05ccea83847309484be3781c ]
+
+Following line should listen for a rising edge and exit after the first
+one since '-c 1' is provided.
+
+ # gpio-event-mon -n gpiochip1 -o 0 -r -c 1
+
+It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the
+above command doesn't exit after the first rising edge it keep listening
+for an event forever. The '-c 1' is not taken into an account.
+The problem is in commit 62757c32d5db ("tools: gpio: add multi-line
+monitoring to gpio-event-mon").
+Before this commit the iterator 'i' in monitor_device() is used for
+counting of the events (loops). In the case of the above command (-c 1)
+we should start from 0 and increment 'i' only ones and hit the 'break'
+statement and exit the process. But after the above commit counting
+doesn't start from 0, it start from 1 when we listen on one line.
+It is because 'i' is used from one more purpose, counting of lines
+(num_lines) and it isn't restore to 0 after following code
+
+ for (i = 0; i < num_lines; i++)
+ gpiotools_set_bit(&values.mask, i);
+
+Restore the initial value of the iterator to 0 in order to allow counting
+of loops to work for any cases.

+
+[ Upstream commit 262b42e02d1e0b5ad1b33e9b9842e178c16231de ]
+
+I'm not exactly clear on what strange workflow causes people to do it,
+but clearly occasionally some files end up being committed as executable
+even though they clearly aren't.
+
+This is a reprise of commit 90fda63fa115 ("treewide: fix up files
+incorrectly marked executable"), just with a different set of files (but
+with the same trivial shell scripting).
+
+So apparently we need to re-do this every five years or so, and Joe
+needs to just keep reminding me to do so ;)
