      add time64 symbol name redirects to public headers, under arch control · 1febd21d
      Rich Felker 提交于
      a _REDIR_TIME64 macro is introduced, which the arch's alltypes.h is
      expected to define, to control redirection of symbol names for
      interfaces that involve time_t and derived types. this ensures that
      object files will only be linked to libc interfaces matching the ABI
      whose headers they were compiled against.
      
      along with time32 compat shims, which will be introduced separately,
      the redirection also makes it possible for a single libc (static or
      shared) to be used with object files produced with either the old
      (32-bit time_t) headers or the new ones after 64-bit time_t switchover
      takes place. mixing of such object files (or shared libraries) in the
      same program will also be possible, but must be done with care; ABI
      between libc and a consumer of the libc interfaces is guaranteed to
      match by the the symbol name redirection, but pairwise ABI between
      consumers of libc that define interfaces between each other in terms
      of time_t is not guaranteed to match.
      
      this change adds a dependency on an additional "GNU C" feature to the
      public headers for existing 32-bit archs, which is generally
      undesirable; however, the feature is one which glibc has depended on
      for a long time, and thus which any viable alternative compiler is
      going to need to provide. 64-bit archs are not affected, nor will
      future 32-bit archs be, regardless of whether they are "new" on the
      kernel side (e.g. riscv32) or just newly-added (e.g. a new sparc or
      xtensa port). the same applies to newly-added ABIs for existing
      machine-level archs.

      make brace placement in public header struct definitions consistent · befa5866
      Rich Felker 提交于
      placing the opening brace on the same line as the struct keyword/tag
      is the style I prefer and seems to be the prevailing practice in more
      recent additions.
      
      these changes were generated by the command:
      
      find include/ arch/*/bits -name '*.h' \
      -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} +
      
      and subsequently checked by hand to ensure that the regex did not pick
      up any false positives.

      avoid padding gaps in struct sockaddr_storage · 1e6fc0b6
      Rich Felker 提交于
      compilers are free not to copy, or in some cases to clobber, padding
      bytes in a structure. while it's an aliasing violation, and thus
      undefined behavior, to copy or manipulate other sockaddr types using
      sockaddr_storage, it seems likely that traditional code attempts to do
      so, and the original intent of the sockaddr_storage structure was
      probably to allow such usage.
      
      in the interest of avoiding silent and potentially dangerous breakage,
      ensure that there are no actual padding bytes in sockaddr_storage by
      moving and adjusting the size of the __ss_padding member so that it
      fits exactly.
      
      this change also removes a silent assumption that the alignment of
      long is equal to its size.

      Szabolcs Nagy 提交于
      these socket options are new in linux v3.19, introduced in commit
      2c8c56e15df3d4c2af3d656e44feb18789f75837 and commit

      with SO_INCOMING_CPU the cpu can be queried on which a socket is
      managed inside the kernel and optimize polling of large number of
      sockets accordingly.
      
      SO_ATTACH_BPF lets eBPF programs (created by the bpf syscall) to
      be attached to sockets.

      fix remaining known namespace violations for netinet/in.h · acde0135
      Rich Felker 提交于
      the imr_, imsf_, ip6_, ip6m_, ipi_, ipi6_, SCM_, and SOL_ prefixes are
      not in the reserved namespace for this header. thus the constants and
      structures using them need to be protected under appropriate feature
      test macros.
      
      this also affects some headers which are permitted to include
      netinet/in.h, particularly netdb.h and arpa/inet.h.
      
      the SOL_ macros are moved to sys/socket.h where they are in the
      reserved namespace (SO*). they are still accessible via netinet/in.h
      since it includes sys/socket.h implicitly (which is permitted).
      
      the SCM_SRCRT macro is simply removed, since the definition used for
      it, IPV6_RXSRCRT is not defined anywhere. it could be re-added, this
      time in sys/socket.h, if the appropriate value can be determined;
      however, given that the erroneous definition was not caught, it is
      unlikely that any software actually attempts to use SCM_SRCRT.
