2023-04-05Migrate the PCIe-IDIO-24 and WS16C48 GPIO driversMark Brown1-3/+5
Merge series from William Breathitt Gray <william.gray@linaro.org>: The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. A patch to pass irq_drv_data as a parameter for struct regmap_irq_chip set_type_config() is included. This is needed by the idio_24_set_type_config() and ws16c48_set_type_config() callbacks in order to update the type configuration on their respective devices.

2023-04-05regmap: Use mas_walk() instead of mas_find()Mark Brown1-2/+2
Liam recommends using mas_walk() instead of mas_find() for our use case so let's do that, it avoids some minor overhead associated with being able to restart the operation which we don't need since we do a simple search.

2023-04-03regmap: Add maple tree based register cacheMark Brown5-1/+284
The current state of the art for sparse register maps is the rbtree cache. This works well for most applications but isn't always ideal for sparser register maps since the rbtree can get deep, requiring a lot of walking. Fortunately the kernel has a data structure intended to address this very problem, the maple tree. Provide an initial implementation of a register cache based on the maple tree to start taking advantage of it. The entries stored in the maple tree are arrays of register values, with the maple tree keys holding the register addresses. We store data in host native format rather than device native format as we do for rbtree, this will be a benefit for devices where we don't marshal data within regmap and simplifies the code but will result in additional CPU overhead when syncing the cache on devices where we do marshal data in regmap. This should work well for a lot of devices, though there's some additional areas that could be looked at such as caching the last accessed entry like we do for rbtree and trying to minimise the maple tree level locking. We should also use bulk writes rather than single register writes when resyncing the cache where possible, even if we don't store in device native format. Very small register maps may continue to to better with rbtree longer term.

2023-03-30regmap: Add some basic kunit testsMark Brown3-0/+744
On the theory that it's better to make a start let's add some KUnit tests for regmap. Currently this is a bit of a mess but it passes and hopefully will at some point help catch problems. We provide very basic cover for most of the core functionality that operates at the register level, repeating each test for each cache type in order to exercise the caches. There is no coverage of anything to do with the bulk operations at the bus level or formatting for byte stream buses yet. Each test creates it's own regmap since the cache structures are built incrementally, meaning we gain coverage from the different access patterns, and some of the tests cover different init scenarios.

2023-03-30regmap: Add RAM backed register mapMark Brown4-0/+108
Add a register map that is a simple array of memory, for use in KUnit testing of the framework. This is not exposed in regmap.h since I can't think of a non-test use case, it is purely for use internally. To facilitate testing we track if registers have been read or written to.

2023-03-29regmap: Removed compressed cache supportMark Brown5-378/+0
The compressed register cache support has assumptions that make it hard to cover in testing, mainly that it requires raw registers defaults be provided. Rather than either address these assumptions or leave it untested by the forthcoming KUnit tests let's remove it, the use case is quite thin and there are no current users.

2023-03-27regmap: Clarify error for unknown cache typesMark Brown1-1/+1
The error message printed when we fail to locate the cache type the map requested says it can't find a compress type rather than a cache type, fix that. Since the compressed type is the only one currently compiled conditionally it's likely to be the missing type but that might not always be true and is still unclear.

2023-03-18media: m5mols: fix off-by-one loop termination errorLinus Torvalds1-1/+1
The __find_restype() function loops over the m5mols_default_ffmt[] array, and the termination condition ends up being wrong: instead of stopping when the iterator becomes the size of the array it traverses, it stops after it has already overshot the array. Now, in practice this doesn't likely matter, because the code will always find the entry it looks for, and will thus return early and never hit that last extra iteration. But it turns out that clang will unroll the loop fully, because it has only two iterations (well, three due to the off-by-one bug), and then clang will end up just giving up in the middle of the loop unrolling when it notices that the code walks past the end of the array. And that made 'objtool' very unhappy indeed, because the generated code just falls off the edge of the universe, and ends up falling through to the next function, causing this warning: drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc() Fix the loop ending condition.

2023-03-17bonding: restore bond's IFF_SLAVE flag if a non-eth dev enslave failsNikolay Aleksandrov1-3/+1
syzbot reported a warning[1] where the bond device itself is a slave and we try to enslave a non-ethernet device as the first slave which fails but then in the error path when ether_setup() restores the bond device it also clears all flags. In my previous fix[2] I restored the IFF_MASTER flag, but I didn't consider the case that the bond device itself might also be a slave with IFF_SLAVE set, so we need to restore that flag as well. Use the bond_ether_setup helper which does the right thing and restores the bond's flags properly. Steps to reproduce using a nlmon dev: $ ip l add nlmon0 type nlmon $ ip l add bond1 type bond $ ip l add bond2 type bond $ ip l set bond1 master bond2 $ ip l set dev nlmon0 master bond1 $ ip -d l sh dev bond1 22: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noqueue master bond2 state DOWN mode DEFAULT group default qlen 1000 (now bond1's IFF_SLAVE flag is gone and we'll hit a warning[3] if we try to delete it) [1] https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef [2] commit 7d5cd2ce5292 ("bonding: correctly handle bonding type change on enslave failure") [3] example warning: [ 27.008664] bond1: (slave nlmon0): The slave device specified does not support setting the MAC address [ 27.008692] bond1: (slave nlmon0): Error -95 calling set_mac_address [ 32.464639] bond1 (unregistering): Released all slaves [ 32.464685] ------------[ cut here ]------------ [ 32.464686] WARNING: CPU: 1 PID: 2004 at net/core/dev.c:10829 unregister_netdevice_many+0x72a/0x780 [ 32.464694] Modules linked in: br_netfilter bridge bonding virtio_net [ 32.464699] CPU: 1 PID: 2004 Comm: ip Kdump: loaded Not tainted 5.18.0-rc3+ #47 [ 32.464703] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.1-2.fc37 04/01/2014 [ 32.464704] RIP: 0010:unregister_netdevice_many+0x72a/0x780 [ 32.464707] Code: 99 fd ff ff ba 90 1a 00 00 48 c7 c6 f4 02 66 96 48 c7 c7 20 4d 35 96 c6 05 fa c7 2b 02 01 e8 be 6f 4a 00 0f 0b e9 73 fd ff ff <0f> 0b e9 5f fd ff ff 80 3d e3 c7 2b 02 00 0f 85 3b fd ff ff ba 59 [ 32.464710] RSP: 0018:ffffa006422d7820 EFLAGS: 00010206 [ 32.464712] RAX: ffff8f6e077140a0 RBX: ffffa006422d7888 RCX: 0000000000000000 [ 32.464714] RDX: ffff8f6e12edbe58 RSI: 0000000000000296 RDI: ffffffff96d4a520 [ 32.464716] RBP: ffff8f6e07714000 R08: ffffffff96d63600 R09: ffffa006422d7728 [ 32.464717] R10: 0000000000000ec0 R11: ffffffff9698c988 R12: ffff8f6e12edb140 [ 32.464719] R13: dead000000000122 R14: dead000000000100 R15: ffff8f6e12edb140 [ 32.464723] FS: 00007f297c2f1740(0000) GS:ffff8f6e5d900000(0000) knlGS:0000000000000000 [ 32.464725] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 32.464726] CR2: 00007f297bf1c800 CR3: 00000000115e8000 CR4: 0000000000350ee0 [ 32.464730] Call Trace: [ 32.464763] <TASK> [ 32.464767] rtnl_dellink+0x13e/0x380 [ 32.464776] ? cred_has_capability.isra.0+0x68/0x100 [ 32.464780] ? __rtnl_unlock+0x33/0x60 [ 32.464783] ? bpf_lsm_capset+0x10/0x10 [ 32.464786] ? security_capable+0x36/0x50 [ 32.464790] rtnetlink_rcv_msg+0x14e/0x3b0 [ 32.464792] ? _copy_to_iter+0xb1/0x790 [ 32.464796] ? post_alloc_hook+0xa0/0x160 [ 32.464799] ? rtnl_calcit.isra.0+0x110/0x110 [ 32.464802] netlink_rcv_skb+0x50/0xf0 [ 32.464806] netlink_unicast+0x216/0x340 [ 32.464809] netlink_sendmsg+0x23f/0x480 [ 32.464812] sock_sendmsg+0x5e/0x60 [ 32.464815] ____sys_sendmsg+0x22c/0x270 [ 32.464818] ? import_iovec+0x17/0x20 [ 32.464821] ? sendmsg_copy_msghdr+0x59/0x90 [ 32.464823] ? do_set_pte+0xa0/0xe0 [ 32.464828] ___sys_sendmsg+0x81/0xc0 [ 32.464832] ? mod_objcg_state+0xc6/0x300 [ 32.464835] ? refill_obj_stock+0xa9/0x160 [ 32.464838] ? memcg_slab_free_hook+0x1a5/0x1f0 [ 32.464842] __sys_sendmsg+0x49/0x80 [ 32.464847] do_syscall_64+0x3b/0x90 [ 32.464851] entry_SYSCALL_64_after_hwframe+0x44/0xae [ 32.464865] RIP: 0033:0x7f297bf2e5e7 [ 32.464868] Code: 64 89 02 48 c7 c0 ff ff ff ff eb bb 0f 1f 80 00 00 00 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 b8 2e 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 51 c3 48 83 ec 28 89 54 24 1c 48 89 74 24 10 [ 32.464869] RSP: 002b:00007ffd96c824c8 EFLAGS: 00000246 ORIG_RAX: 000000000000002e [ 32.464872] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f297bf2e5e7 [ 32.464874] RDX: 0000000000000000 RSI: 00007ffd96c82540 RDI: 0000000000000003 [ 32.464875] RBP: 00000000640f19de R08: 0000000000000001 R09: 000000000000007c [ 32.464876] R10: 00007f297bffabe0 R11: 0000000000000246 R12: 0000000000000001 [ 32.464877] R13: 00007ffd96c82d20 R14: 00007ffd96c82610 R15: 000055bfe38a7020 [ 32.464881] </TASK> [ 32.464882] ---[ end trace 0000000000000000 ]--- Fixes: 7d5cd2ce5292 ("bonding: correctly handle bonding type change on enslave failure") Reported-by: syzbot+9dfc3f3348729cc82277@syzkaller.appspotmail.com Link: https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Reviewed-by: Michal Kubiak <michal.kubiak@intel.com> Acked-by: Jonathan Toppins <jtoppins@redhat.com> Acked-by: Jay Vosburgh <jay.vosburgh@canonical.com> Signed-off-by: David S.

2023-03-17bonding: restore IFF_MASTER/SLAVE flags on bond enslave ether type changeNikolay Aleksandrov1-4/+15
Add bond_ether_setup helper which is used to fix ether_setup() calls in the bonding driver. It takes care of both IFF_MASTER and IFF_SLAVE flags, the former is always restored and the latter only if it was set. If the bond enslaves non-ARPHRD_ETHER device (changes its type), then releases it and enslaves ARPHRD_ETHER device (changes back) then we use ether_setup() to restore the bond device type but it also resets its flags and removes IFF_MASTER and IFF_SLAVE[1]. Use the bond_ether_setup helper to restore both after such transition. [1] reproduce (nlmon is non-ARPHRD_ETHER): $ ip l add nlmon0 type nlmon $ ip l add bond2 type bond mode active-backup $ ip l set nlmon0 master bond2 $ ip l set nlmon0 nomaster $ ip l add bond1 type bond (we use bond1 as ARPHRD_ETHER device to restore bond2's mode) $ ip l set bond1 master bond2 $ ip l sh dev bond2 37: bond2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether be:d7:c5:40:5b:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 1500 (notice bond2's IFF_MASTER is missing) Fixes: e36b9d16c6a6 ("bonding: clean muticast addresses when device changes type") Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

A recent commit defined HW_PARAM_4 as a GSI register ID but did not add it to gsi_reg_id_valid() to indicate it's valid (for IPA v5.0+). Add version checks for the HW_PARAM_2 and INTER_EE IRQ GSI registers there as well. IPA v5.0 supports up to 8 source and destination resource groups. Update the validity check (and the comments where the register IDs are defined) to reflect that. Similarly update comments and validity checks for the hash/cache-related registers. Note that this patch fixes an omission and constrains things further, but these don't technically represent bugs.

And although there *exists* a FILT_ROUT_CACHE_CFG register, it is not needed in upstream code. So get rid of definitions related to FILT_ROUT_CACHE_CFG, because they are not needed.

2023-03-17net: dsa: microchip: fix RGMII delay configuration on KSZ8765/KSZ8794/KSZ8795Marek Vasut1-1/+1
The blamed commit has replaced a ksz_write8() call to address REG_PORT_5_CTRL_6 (0x56) with a ksz_set_xmii() -> ksz_pwrite8() call to regs[P_XMII_CTRL_1], which is also defined as 0x56 for ksz8795_regs[]. The trouble is that, when compared to ksz_write8(), ksz_pwrite8() also adjusts the register offset with the port base address. So in reality, ksz_pwrite8(offset=0x56) accesses register 0x56 + 0x50 = 0xa6, which in this switch appears to be unmapped, and the RGMII delay configuration on the CPU port does nothing. So if the switch wasn't fine with the RGMII delay configuration done through pin strapping and relied on Linux to apply a different one in order to pass traffic, this is now broken. Using the offset translation logic imposed by ksz_pwrite8(), the correct value for regs[P_XMII_CTRL_1] should have been 0x6 on ksz8795_regs[], in order to really end up accessing register 0x56. Static code analysis shows that, despite there being multiple other accesses to regs[P_XMII_CTRL_1] in this driver, the only code path that is applicable to ksz8795_regs[] and ksz8_dev_ops is ksz_set_xmii(). Therefore, the problem is isolated to RGMII delays. In its current form, ksz8795_regs[] contains the same value for P_XMII_CTRL_0 and for P_XMII_CTRL_1, and this raises valid suspicions that writes made by the driver to regs[P_XMII_CTRL_0] might overwrite writes made to regs[P_XMII_CTRL_1] or vice versa. Again, static analysis shows that the only accesses to P_XMII_CTRL_0 from the driver are made from code paths which are not reachable with ksz8_dev_ops. So the accesses made by ksz_set_xmii() are safe for this switch family.

2023-03-17net: atlantic: Fix crash when XDP is enabled but no program is loadedToke Høiland-Jørgensen1-7/+21
The aq_xdp_run_prog() function falls back to the XDP_ABORTED action handler (using a goto) if the operations for any of the other actions fail. The XDP_ABORTED handler in turn calls the bpf_warn_invalid_xdp_action() tracepoint. However, the function also jumps into the XDP_PASS helper if no XDP program is loaded on the device, which means the XDP_ABORTED handler can be run with a NULL program pointer. This results in a NULL pointer deref because the tracepoint dereferences the 'prog' pointer passed to it. This situation can happen in multiple ways: - If a packet arrives between the removal of the program from the interface and the static_branch_dec() in aq_xdp_setup() - If there are multiple devices using the same driver in the system and one of them has an XDP program loaded and the other does not. Fix this by refactoring the aq_xdp_run_prog() function to remove the 'goto pass' handling if there is no XDP program loaded. Instead, factor out the skb building in a separate small helper function.
