Normally I would've just deferred it to next week, but since the original fix got picked up by stable, I think it's better to just send this one off separately. The issue is around the poll race fix, and how it mistakenly also got applied to multishot polling. Those don't need the race fix, and we should not be doing any reissues for that case. Exhaustive test cases were written and committed to the liburing regression suite for the reported issue, and additions for similar issues" * tag 'io_uring-6.2-2023-01-21' of git://git.kernel.dk/linux: io_uring/poll: don't reissue in case of poll race on multishot request 22 January 2023, 00:21:56 UTC

f3bbac3 Linus Torvalds 18 January 2023, 04:27:23 UTC ext4: deal with legacy signed xattr name hash values We potentially have old hashes of the xattr names generated on systems with signed 'char' types. Now that everybody uses '-funsigned-char', those hashes will no longer match. This only happens if you use xattrs names that have the high bit set, which probably doesn't happen in practice, but the xfstest generic/454 shows it. Instead of adding a new "signed xattr hash filesystem" bit and having to deal with all the possible combinations, just calculate the hash both ways if the first one fails, and always generate new hashes with the proper unsigned char version.

8caa03f Jens Axboe 20 January 2023, 22:08:21 UTC io_uring/poll: don't reissue in case of poll race on multishot request A previous commit fixed a poll race that can occur, but it's only applicable for multishot requests. For a multishot request, we can safely ignore a spurious wakeup, as we never leave the waitqueue to begin with. A blunt reissue of a multishot armed request can cause us to leak a buffer, if they are ring provided. While this seems like a bug in itself, it's not really defined behavior to reissue a multishot request directly. It's less efficient to do so as well, and not required to rearm anything like it is for singleshot poll requests.

First, once we queue it the target ring can go away and so setting IORING_SQ_TASKRUN there is not safe. Secondly, the userspace might not expect IORING_SQ_TASKRUN. Extract a helper and uniformly use TWA_SIGNAL without TWA_SIGNAL_NO_IPI tricks for now, just as it was done in the original patch.

aaca766 Elliot Berman 12 January 2023, 18:23:12 UTC misc: fastrpc: Pass bitfield into qcom_scm_assign_mem The srcvm parameter of qcom_scm_assign_mem is a pointer to a bitfield of VMIDs. The bitfield is updated with which VMIDs have permissions after the qcom_scm_assign_mem call. This makes it simpler for clients to make qcom_scm_assign_mem calls later, they always pass in same srcvm bitfield and do not need to closely track whether memory was originally shared. When restoring permissions to HLOS, fastrpc is incorrectly using the first VMID directly -- neither the BIT nor the other possible VMIDs the memory was already assigned to. We already have a field intended for this purpose: "perms" in the struct fastrpc_channel_ctx, but it was never used. Start using the perms field.

Rewrite fastrpc_map_get() to only increase the reference count of a map if it's non-zero. Propagate this to callers so they can know if a map is about to be deleted.

9446fa1 Abel Vesa 24 November 2022, 17:49:39 UTC misc: fastrpc: Fix use-after-free and race in fastrpc_map_find Currently, there is a race window between the point when the mutex is unlocked in fastrpc_map_lookup and the reference count increasing (fastrpc_map_get) in fastrpc_map_find, which can also lead to use-after-free. So lets merge fastrpc_map_find into fastrpc_map_lookup which allows us to both protect the maps list by also taking the &fl->lock spinlock and the reference count, since the spinlock will be released only after. Add take_ref argument to make this suitable for all callers.

fdfc76a Andrew Halaney 18 January 2023, 16:56:38 UTC net: stmmac: enable all safety features by default In the original implementation of dwmac5 commit 8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default. Later it seems some implementations didn't have support for all the features, so in commit 5ac712dcdfef ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features. The problem is that only certain platforms were given that software support. If the automotive safety package bit is set in the hardware features register the safety feature callback is called for the platform, and for platforms that didn't get a safety_feat_cfg defined this results in the following NULL pointer dereference: [ 7.933303] Call trace: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] ____sys_sendmsg+0x218/0x280 [ 7.997249] ___sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194 Go back to the original behavior, if the automotive safety package is found to be supported in hardware enable all the features unless safety_feat_cfg is passed in saying this particular platform only supports a subset of the features.

This field is referred in ksz9477_fdb_del() for clearing forward port map and alu table. But current fdb_del refer ALU table entry 3 register for accessing forward port map. Update ksz9477_fdb_del() to get forward port map from correct alu table entry register. With this bug, issue can be observed while deleting static MAC entries. Delete any specific MAC entry using "bridge fdb del" command. This should clear all the specified MAC entries. But it is observed that entries with self static alone are retained. Tested on LAN9370 EVB since ksz9477_fdb_del() is used common across LAN937x and KSZ series.

The sk waits for req3.tp_retire_blk_tov msec to release a block.

Before to such a commit, the user-space got ENOTCONN instead of EINVAL.

2efb6ed Ian Abbott 03 January 2023, 14:37:54 UTC comedi: adv_pci1760: Fix PWM instruction handling (Actually, this is fixing the "Read the Current Status" command sent to the device's outgoing mailbox, but it is only currently used for the PWM instructions.) The PCI-1760 is operated mostly by sending commands to a set of Outgoing Mailbox registers, waiting for the command to complete, and reading the result from the Incoming Mailbox registers. One of these commands is the "Read the Current Status" command. The number of this command is 0x07 (see the User's Manual for the PCI-1760 at <https://advdownload.advantech.com/productfile/Downloadfile2/1-11P6653/PCI-1760.pdf>. The `PCI1760_CMD_GET_STATUS` macro defined in the driver should expand to this command number 0x07, but unfortunately it currently expands to 0x03. (Command number 0x03 is not defined in the User's Manual.) Correct the definition of the `PCI1760_CMD_GET_STATUS` macro to fix it. This is used by all the PWM subdevice related instructions handled by `pci1760_pwm_insn_config()` which are probably all broken. The effect of sending the undefined command number 0x03 is not known.

5bfdd3c Tobias Schramm 09 January 2023, 07:29:40 UTC serial: atmel: fix incorrect baudrate setup Commit ba47f97a18f2 ("serial: core: remove baud_rates when serial console setup") changed uart_set_options to select the correct baudrate configuration based on the absolute error between requested baudrate and available standard baudrate settings. Prior to that commit the baudrate was selected based on which predefined standard baudrate did not exceed the requested baudrate. This change of selection logic was never reflected in the atmel serial driver. Thus the comment left in the atmel serial driver is no longer accurate. Additionally the manual rounding up described in that comment and applied via (quot - 1) requests an incorrect baudrate. Since uart_set_options uses tty_termios_encode_baud_rate to determine the appropriate baudrate flags this can cause baudrate selection to fail entirely because tty_termios_encode_baud_rate will only select a baudrate if relative error between requested and selected baudrate does not exceed +/-2%. Fix that by requesting actual, exact baudrate used by the serial.

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.

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.

3f4ca5f Jason Xing 18 January 2023, 01:59:41 UTC tcp: avoid the lookup process failing to get sk in ehash table While one cpu is working on looking up the right socket from ehash table, another cpu is done deleting the request socket and is about to add (or is adding) the big socket from the table. It means that we could miss both of them, even though it has little chance. Let me draw a call trace map of the server side. CPU 0 CPU 1 ----- ----- tcp_v4_rcv() syn_recv_sock() inet_ehash_insert() -> sk_nulls_del_node_init_rcu(osk) __inet_lookup_established() -> __sk_nulls_add_node_rcu(sk, list) Notice that the CPU 0 is receiving the data after the final ack during 3-way shakehands and CPU 1 is still handling the final ack. Why could this be a real problem? This case is happening only when the final ack and the first data receiving by different CPUs. Then the server receiving data with ACK flag tries to search one proper established socket from ehash table, but apparently it fails as my map shows above. After that, the server fetches a listener socket and then sends a RST because it finds a ACK flag in the skb (data), which obeys RST definition in RFC 793. Besides, Eric pointed out there's one more race condition where it handles tw socket hashdance. Only by adding to the tail of the list before deleting the old one can we avoid the race if the reader has already begun the bucket traversal and it would possibly miss the head. Many thanks to Eric for great help from beginning to end.

The commit broke suspend/resume since apple_nvme_reset_work() tries to disable the controller on resume. This does not work for the apple NVMe controller since register access only works while the co-processor firmware is running. Disabling the NVMe controller in the shutdown path is also required for shutting the co-processor down. The original code was appropriate for this hardware.

Currently IFF_NO_ADDRCONF is used to prevent all ipv6 addrconf for the slave ports of team, bonding and failover devices and it means no ipv6 packets can be sent out through these slave ports. However, for team device, "nsna_ping" link_watch requires ipv6 addrconf. Otherwise, the link will be marked failure. This patch removes the IFF_NO_ADDRCONF flag set for team port, and we will fix the original issue in another patch, as Jakub suggested.
