2024-02-29gpio: nomadik: make clock optionalThéo Lebrun
Not all platforms using this platform driver expose a clock for this GPIO controller. Turn devm_clk_get() into devm_clk_get_optional() to avoid failing when no clocks are provided.

2024-02-29gpio: nomadik: request dynamic ID allocationThéo Lebrun
Move away from statically allocated GPIO IDs. Switch to dynamic ID allocation. Static IDs are deprecated because they cause issues when multiple GPIO controllers are to be found on the same platform. Add a bit of complexity to do pin number -> GPIO chip + offset. Previously, bank number and offsets were retrieved using division and remainder (bank size being constant 32). Now, to get the pin number matching a bank base, we must know the sum of ngpios of previous banks. This is done in find_nmk_gpio_from_pin() which also exposes the offset inside the bank. Also remove the assumption that bank sizes are constant. Instead of using NMK_GPIO_PER_CHIP as bank size, use nmk_gpio_chips[i]->ngpio.

2024-02-29gpio: nomadik: extract GPIO platform driver from drivers/pinctrl/nomadik/Théo Lebrun
Previously, drivers/pinctrl/nomadik/pinctrl-nomadik.c registered two platform drivers: pinctrl & GPIO. Move the GPIO aspect to the drivers/gpio/ folder, as would be expected. Both drivers are intertwined for a reason; pinctrl requires access to GPIO registers for pinmuxing, pull-disable, disabling interrupts while setting the muxing and wakeup control. Information sharing is done through a shared array containing GPIO chips and a few helper functions. That shared array is not touched from gpio-nomadik when CONFIG_PINCTRL_NOMADIK is not defined. Make no change to the code that moved into gpio-nomadik; there should be no behavior change following. A few functions are shared and header comments are added. Checkpatch warnings are addressed. NUM_BANKS is renamed to NMK_MAX_BANKS. It is supported to compile gpio-nomadik without pinctrl-nomadik. The opposite is not true.

2024-02-29gpio: nomadik: fix offset bug in nmk_pmx_set()Théo Lebrun
Previously, the statement looked like: slpm[x] &= ~BIT(g->grp.pins[i]); Where: - slpm is a unsigned int pointer; - g->grp.pins[i] is a pin number. It can grow to more than 32. The expected shift amount is a pin bank offset. This bug does not occur on every group or pin: the altsetting must be NMK_GPIO_ALT_C and the pin must be 32 or above. It might have occured. For example, in pinctrl-nomadik-db8500.c, pin group i2c3_c_2 has the right altsetting and pins 229 and 230.

Robert Marko says: ==================== net: dsa: mv88e6xxx: add Amethyst specific SMI GPIO function Amethyst family (MV88E6191X/6193X/6393X) has a simplified SMI GPIO setting via the Scratch and Misc register so it requires family specific function.

2024-02-29net: dsa: mv88e6xxx: add Amethyst specific SMI GPIO functionRobert Marko
The existing mv88e6390_g2_scratch_gpio_set_smi() cannot be used on the 88E6393X as it requires certain P0_MODE, it also checks the CPU mode as it impacts the bit setting value. This is all irrelevant for Amethyst (MV88E6191X/6193X/6393X) as only the default value of the SMI_PHY Config bit is set to CPU_MGD bootstrap pin value but it can be changed without restrictions so that GPIO pins 9 and 10 are used as SMI pins. So, introduce Amethyst specific function and call that if the Amethyst family wants to setup the external PHY.

2024-02-28inet6: expand rcu_read_lock() scope in inet6_dump_addr()Eric Dumazet
I missed that inet6_dump_addr() is calling in6_dump_addrs() from two points. First one under RTNL protection, and second one under rcu_read_lock(). Since we want to remove RTNL use from inet6_dump_addr() very soon, no longer assume in6_dump_addrs() is protected by RTNL (even if this is still the case). Use rcu_read_lock() earlier to fix this lockdep splat: WARNING: suspicious RCU usage 6.8.0-rc5-syzkaller-01618-gf8cbf6bde4c8 #0 Not tainted net/ipv6/addrconf.c:5317 suspicious rcu_dereference_check() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 3 locks held by syz-executor.2/8834: #0: ffff88802f554678 (nlk_cb_mutex-ROUTE){+.+.}-{3:3}, at: __netlink_dump_start+0x119/0x780 net/netlink/af_netlink.c:2338 #1: ffffffff8f377a88 (rtnl_mutex){+.+.}-{3:3}, at: netlink_dump+0x676/0xda0 net/netlink/af_netlink.c:2265 #2: ffff88807e5f0580 (&ndev->lock){++--}-{2:2}, at: in6_dump_addrs+0xb8/0x1de0 net/ipv6/addrconf.c:5279 stack backtrace: CPU: 1 PID: 8834 Comm: syz-executor.2 Not tainted 6.8.0-rc5-syzkaller-01618-gf8cbf6bde4c8 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/25/2024 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0x1e7/0x2e0 lib/dump_stack.c:106 lockdep_rcu_suspicious+0x220/0x340 kernel/locking/lockdep.c:6712 in6_dump_addrs+0x1b47/0x1de0 net/ipv6/addrconf.c:5317 inet6_dump_addr+0x1597/0x1690 net/ipv6/addrconf.c:5428 netlink_dump+0x6a6/0xda0 net/netlink/af_netlink.c:2266 __netlink_dump_start+0x59d/0x780 net/netlink/af_netlink.c:2374 netlink_dump_start include/linux/netlink.h:340 [inline] rtnetlink_rcv_msg+0xcf7/0x10d0 net/core/rtnetlink.c:6555 netlink_rcv_skb+0x1e3/0x430 net/netlink/af_netlink.c:2547 netlink_unicast_kernel net/netlink/af_netlink.c:1335 [inline] netlink_unicast+0x7ea/0x980 net/netlink/af_netlink.c:1361 netlink_sendmsg+0x8e0/0xcb0 net/netlink/af_netlink.c:1902 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg+0x221/0x270 net/socket.c:745 ____sys_sendmsg+0x525/0x7d0 net/socket.c:2584 ___sys_sendmsg net/socket.c:2638 [inline] __sys_sendmsg+0x2b0/0x3a0 net/socket.c:2667 Fixes: c3718936ec47 ("ipv6: anycast: complete RCU handling of struct ifacaddr6") Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Link: https://lore.kernel.org/r/20240227222259.4081489-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-02-29kernel-doc: Add unary operator * to $type_param_refAkira Yokosawa
In kernel-doc comments, unary operator * collides with Sphinx/ docutil's markdown for emphasizing. This resulted in additional warnings from "make htmldocs": WARNING: Inline emphasis start-string without end-string. , as reported recently [1]. Those have been worked around either by escaping * (like \*param) or by using inline-literal form of ``*param``, both of which are specific to Sphinx/docutils. Such workarounds are against the kenrel-doc's ideal and should better be avoided. Instead, add "*" to the list of unary operators kernel-doc recognizes and make the form of *@param available in kernel-doc comments.

2024-02-28igb: extend PTP timestamp adjustments to i211Oleksij Rempel
The i211 requires the same PTP timestamp adjustments as the i210, according to its datasheet. To ensure consistent timestamping across different platforms, this change extends the existing adjustments to include the i211. The adjustment result are tested and comparable for i210 and i211 based systems.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now.

2024-02-28rtnetlink: fix error logic of IFLA_BRIDGE_FLAGS writing backLin Ma
In the commit d73ef2d69c0d ("rtnetlink: let rtnl_bridge_setlink checks IFLA_BRIDGE_MODE length"), an adjustment was made to the old loop logic in the function `rtnl_bridge_setlink` to enable the loop to also check the length of the IFLA_BRIDGE_MODE attribute. However, this adjustment removed the `break` statement and led to an error logic of the flags writing back at the end of this function. if (have_flags) memcpy(nla_data(attr), &flags, sizeof(flags)); // attr should point to IFLA_BRIDGE_FLAGS NLA !!! Before the mentioned commit, the `attr` is granted to be IFLA_BRIDGE_FLAGS. However, this is not necessarily true fow now as the updated loop will let the attr point to the last NLA, even an invalid NLA which could cause overflow writes. This patch introduces a new variable `br_flag` to save the NLA pointer that points to IFLA_BRIDGE_FLAGS and uses it to resolve the mentioned error logic.
