      certs: Convert spaces in certs/Makefile to a tab · d56fd986
      David Howells 提交于
      There's a rule in certs/Makefile for which the command begins with eight
      spaces.  This results in:
      
              ../certs/Makefile:21: FORCE prerequisite is missing
              ../certs/Makefile:21: *** missing separator.  Stop.

      dt-bindings: display: arm,malidp: remove bogus RQOS property · 0b9431c8
      Andre Przywara 提交于
      As Liviu pointed out, the arm,malidp-arqos-high-level property
      mentioned in the original .txt binding was a mistake, and
      arm,malidp-arqos-value needs to take its place.
      
      The binding commit ce6eb025 ("dt/bindings: display: Add optional
      property node define for Mali DP500") mentions the right name in the
      commit message, but has the wrong name in the diff.
      Commit d298e6a2 ("drm/arm/mali-dp: Add display QoS interface
      configuration for Mali DP500") uses the property in the driver, but uses
      the shorter name.
      
      Remove the wrong property from the binding, and use the proper name in
      the example. The actual property was already documented properly.
      
      Fixes: 2c8b082a ("dt-bindings: display: convert Arm Mali-DP to DT schema")

      dt-bindings: pinctrl: ralink: Fix 'enum' lists with duplicate entries · 01aa6cbf
      Rob Herring 提交于
      There's no reason to list the same value twice in an 'enum'. This was fixed
      treewide in commit c3b00681 ("dt-bindings: Fix 'enum' lists with

      In the awk script, there was a typo with the comparison operator when
      checking if the matched pattern is inside an Enum block.
      This prevented the generation of the whole sysreg-defs.h header.

      net: seg6: fix seg6_lookup_any_nexthop() to handle VRFs using flowi_l3mdev · a3bd2102
      Andrea Mayer 提交于
      Commit 40867d74 ("net: Add l3mdev index to flow struct and avoid oif
      reset for port devices") adds a new entry (flowi_l3mdev) in the common
      flow struct used for indicating the l3mdev index for later rule and
      table matching.
      The l3mdev_update_flow() has been adapted to properly set the
      flowi_l3mdev based on the flowi_oif/flowi_iif. In fact, when a valid
      flowi_iif is supplied to the l3mdev_update_flow(), this function can
      update the flowi_l3mdev entry only if it has not yet been set (i.e., the
      flowi_l3mdev entry is equal to 0).
      
      The SRv6 End.DT6 behavior in VRF mode leverages a VRF device in order to
      force the routing lookup into the associated routing table. This routing
      operation is performed by seg6_lookup_any_nextop() preparing a flowi6
      data structure used by ip6_route_input_lookup() which, in turn,
      (indirectly) invokes l3mdev_update_flow().
      
      However, seg6_lookup_any_nexthop() does not initialize the new
      flowi_l3mdev entry which is filled with random garbage data. This
      prevents l3mdev_update_flow() from properly updating the flowi_l3mdev
      with the VRF index, and thus SRv6 End.DT6 (VRF mode)/DT46 behaviors are
      broken.
      
      This patch correctly initializes the flowi6 instance allocated and used
      by seg6_lookup_any_nexhtop(). Specifically, the entire flowi6 instance
      is wiped out: in case new entries are added to flowi/flowi6 (as happened
      with the flowi_l3mdev entry), we should no longer have incorrectly
      initialized values. As a result of this operation, the value of
      flowi_l3mdev is also set to 0.
      
      The proposed fix can be tested easily. Starting from the commit
      referenced in the Fixes, selftests [1],[2] indicate that the SRv6
      End.DT6 (VRF mode)/DT46 behaviors no longer work correctly. By applying
      this patch, those behaviors are back to work properly again.

      this short series includes two fixes for the NFP driver.
      
      1. Restructure GRE+VLAN flower offload to address a miss match
         between the NIC firmware and driver implementation which
         prevented these features from working in combination.
      
      2. Prevent unnecessary warnings regarding rate limiting support.-

         for this feature was added.

      nfp: avoid unnecessary check warnings in nfp_app_get_vf_config · 03d5005f
      Fei Qin 提交于
      nfp_net_sriov_check is added in nfp_app_get_vf_config which intends
      to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be
      read from VF config table only when firmware supports corresponding
      capability.
      
      However, "nfp_app_get_vf_config" can be called by commands like
      "ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan
      $param" (with VF). When using commands above, many warnings
      "ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't
      support VF rate limit and 802.1ad VLAN assingment. If more VFs are
      created, things could get worse.
      
      Thus, this patch add an extra bool parameter for nfp_net_sriov_check
      to enable/disable the cap check warning report. Unnecessary warnings
      in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of
      vf setting function can be reserved.

      netfs: Fix gcc-12 warning by embedding vfs inode in netfs_i_context · 874c8ca1
      David Howells 提交于
      While randstruct was satisfied with using an open-coded "void *" offset
      cast for the netfs_i_context <-> inode casting, __builtin_object_size() as
      used by FORTIFY_SOURCE was not as easily fooled.  This was causing the
      following complaint[1] from gcc v12:
      
        In file included from include/linux/string.h:253,
                         from include/linux/ceph/ceph_debug.h:7,
                         from fs/ceph/inode.c:2:
        In function 'fortify_memset_chk',
            inlined from 'netfs_i_context_init' at include/linux/netfs.h:326:2,
            inlined from 'ceph_alloc_inode' at fs/ceph/inode.c:463:2:
        include/linux/fortify-string.h:242:25: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
          242 |                         __write_overflow_field(p_size_field, size);
              |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      Fix this by embedding a struct inode into struct netfs_i_context (which
      should perhaps be renamed to struct netfs_inode).  The struct inode
      vfs_inode fields are then removed from the 9p, afs, ceph and cifs inode
      structs and vfs_inode is then simply changed to "netfs.inode" in those
      filesystems.
      
      Further, rename netfs_i_context to netfs_inode, get rid of the
      netfs_inode() function that converted a netfs_i_context pointer to an
      inode pointer (that can now be done with &ctx->inode) and rename the
      netfs_i_context() function to netfs_inode() (which is now a wrapper
      around container_of()).
      
      Most of the changes were done with:
      
        perl -p -i -e 's/vfs_inode/netfs.inode/'g \
              `git grep -l 'vfs_inode' -- fs/{9p,afs,ceph,cifs}/*.[ch]`
      
      Kees suggested doing it with a pair structure[2] and a special
      declarator to insert that into the network filesystem's inode
      wrapper[3], but I think it's cleaner to embed it - and then it doesn't
      matter if struct randomisation reorders things.
      
      Dave Chinner suggested using a filesystem-specific VFS_I() function in
      each filesystem to convert that filesystem's own inode wrapper struct
      into the VFS inode struct[4].
      
      Version #2:
       - Fix a couple of missed name changes due to a disabled cifs option.
       - Rename nfs_i_context to nfs_inode
       - Use "netfs" instead of "nic" as the member name in per-fs inode wrapper
         structs.
      
      [ This also undoes commit 507160f4 ("netfs: gcc-12: temporarily
        disable '-Wattribute-warning' for now") that is no longer needed ]

      netfs: gcc-12: temporarily disable '-Wattribute-warning' for now · 507160f4
      Linus Torvalds 提交于
      This is a pure band-aid so that I can continue merging stuff from people
      while some of the gcc-12 fallout gets sorted out.
      
      In particular, gcc-12 is very unhappy about the kinds of pointer
      arithmetic tricks that netfs does, and that makes the fortify checks
      trigger in afs and ceph:
      
        In function ‘fortify_memset_chk’,
            inlined from ‘netfs_i_context_init’ at include/linux/netfs.h:327:2,
            inlined from ‘afs_set_netfs_context’ at fs/afs/inode.c:61:2,
            inlined from ‘afs_root_iget’ at fs/afs/inode.c:543:2:
        include/linux/fortify-string.h:258:25: warning: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
          258 |                         __write_overflow_field(p_size_field, size);
              |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      and the reason is that netfs_i_context_init() is passed a 'struct inode'
      pointer, and then it does
      
              struct netfs_i_context *ctx = netfs_i_context(inode);
      
              memset(ctx, 0, sizeof(*ctx));
      
      where that netfs_i_context() function just does pointer arithmetic on
      the inode pointer, knowing that the netfs_i_context is laid out
      immediately after it in memory.
      
      This is all truly disgusting, since the whole "netfs_i_context is laid
      out immediately after it in memory" is not actually remotely true in
      general, but is just made to be that way for afs and ceph.
      
      See for example fs/cifs/cifsglob.h:
      
        struct cifsInodeInfo {
              struct {
                      /* These must be contiguous */
                      struct inode    vfs_inode;      /* the VFS's inode record */
                      struct netfs_i_context netfs_ctx; /* Netfslib context */
              };
      	[...]
      
      and realize that this is all entirely wrong, and the pointer arithmetic
      that netfs_i_context() is doing is also very very wrong and wouldn't
      give the right answer if netfs_ctx had different alignment rules from a
      'struct inode', for example).
      
      Anyway, that's just a long-winded way to say "the gcc-12 warning is
      actually quite reasonable, and our code happens to work but is pretty
      disgusting".
      
      This is getting fixed properly, but for now I made the mistake of
      thinking "the week right after the merge window tends to be calm for me
      as people take a breather" and I did a sustem upgrade.  And I got gcc-12
      as a result, so to continue merging fixes from people and not have the
      end result drown in warnings, I am fixing all these gcc-12 issues I hit.
      
      Including with these kinds of temporary fixes.

      gcc-12: disable '-Warray-bounds' universally for now · f0be87c4
      Linus Torvalds 提交于
      In commit 8b202ee2 ("s390: disable -Warray-bounds") the s390 people
      disabled the '-Warray-bounds' warning for gcc-12, because the new logic
      in gcc would cause warnings for their use of the S390_lowcore macro,
      which accesses absolute pointers.
      
      It turns out gcc-12 has many other issues in this area, so this takes
      that s390 warning disable logic, and turns it into a kernel build config
      entry instead.
      
      Part of the intent is that we can make this all much more targeted, and
      use this conflig flag to disable it in only particular configurations
      that cause problems, with the s390 case as an example:
      
              select GCC12_NO_ARRAY_BOUNDS
      
      and we could do that for other configuration cases that cause issues.
      
      Or we could possibly use the CONFIG_CC_NO_ARRAY_BOUNDS thing in a more
      targeted way, and disable the warning only for particular uses: again
      the s390 case as an example:
      
        KBUILD_CFLAGS_DECOMPRESSOR += $(if $(CONFIG_CC_NO_ARRAY_BOUNDS),-Wno-array-bounds)
      
      but this ends up just doing it globally in the top-level Makefile, since
      the current issues are spread fairly widely all over:
      
        KBUILD_CFLAGS-$(CONFIG_CC_NO_ARRAY_BOUNDS) += -Wno-array-bounds
      
      We'll try to limit this later, since the gcc-12 problems are rare enough
      that *much* of the kernel can be built with it without disabling this
      warning.

      mellanox: mlx5: avoid uninitialized variable warning with gcc-12 · 842c3b3d
      Linus Torvalds 提交于
      gcc-12 started warning about 'tracker' being used uninitialized:
      
        drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c: In function ‘mlx5_do_bond’:
        drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized]
          786 |         struct lag_tracker tracker;
              |                            ^~~~~~~
      
      which seems to be because it doesn't track how the use (and
      initialization) is bound by the 'do_bond' flag.
      
      But admittedly that 'do_bond' usage is fairly complicated, and involves
      passing it around as an argument to helper functions, so it's somewhat
      understandable that gcc doesn't see how that all works.
      
      This function could be rewritten to make the use of that tracker
      variable more obviously safe, but for now I'm just adding the forced
      initialization of it.

      gcc-12: disable '-Wdangling-pointer' warning for now · 49beadbd
      Linus Torvalds 提交于
      While the concept of checking for dangling pointers to local variables
      at function exit is really interesting, the gcc-12 implementation is not
      compatible with reality, and results in false positives.
      
      For example, gcc sees us putting things on a local list head allocated
      on the stack, which involves exactly those kinds of pointers to the
      local stack entry:
      
        In function ‘__list_add’,
            inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
            inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
        include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
           74 |         new->prev = prev;
              |         ~~~~~~~~~~^~~~~~
      
      But then gcc - understandably - doesn't really understand the big
      picture how the doubly linked list works, so doesn't see how we then end
      up emptying said list head in a loop and the pointer we added has been
      removed.
      
      Gcc also complains about us (intentionally) using this as a way to store
      a kind of fake stack trace, eg
      
        drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
           40 |         acpi_gbl_entry_stack_pointer = &current_sp;
              |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
      
      which is entirely reasonable from a compiler standpoint, and we may want
      to change those kinds of patterns, but not not.
      
      So this is one of those "it would be lovely if the compiler were to
      complain about us leaving dangling pointers to the stack", but not this
      way.

      drm: imx: fix compiler warning with gcc-12 · 7aefd8b5
      Linus Torvalds 提交于
      Gcc-12 correctly warned about this code using a non-NULL pointer as a
      truth value:

              |                     ^
      
      due to the extraneous '&' address-of operator.
      
      Philipp Zabel points out that The mistake had no adverse effect since
      the following condition doesn't actually dereference the NULL pointer,
      but the intent of the code was obviously to check for it, not to take
      the address of the member.
