      cross-arch: don't corrupt personality flags upon exec() · 16f3e95b
      Jiri Kosina 提交于
      Historically, the top three bytes of personality have been used for
      things such as ADDR_NO_RANDOMIZE, which made sense only for specific
      architectures.
      
      We now however have a flag there that is general no matter the
      architecture (UNAME26); generally we have to be careful to preserve the
      personality flags across exec().
      
      This patch tries to fix all architectures that forcefully overwrite
      personality flags during exec() (ppc32 and s390 have been fixed recently
      by commits f9783ec8 ("[S390] Do not clobber personality flags on
      exec") and 59e4c3a2 ("powerpc/32: Don't clobber personality flags on
      exec") in a similar way already).

      Make most arch asm/module.h files use asm-generic/module.h · 786d35d4
      David Howells 提交于
      Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
      ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
      into asm-generic/module.h for all arches bar MIPS.
      
      Also, use the generic definition mod_arch_specific where possible.
      
      To this end, I've defined three new config bools:
      
       (*) HAVE_MOD_ARCH_SPECIFIC
      
           Arches define this if they don't want to use the empty generic
           mod_arch_specific struct.
      
       (*) MODULES_USE_ELF_RELA
      
           Arches define this if their modules can contain RELA records.  This causes
           the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
           defined by the arch rather than have the core emit an error message.
      
       (*) MODULES_USE_ELF_REL
      
           Arches define this if their modules can contain REL records.  This causes
           the Elf_Rel mapping to be emitted and allows apply_relocate() to be
           defined by the arch rather than have the core emit an error message.
      
      Note that it is possible to allow both REL and RELA records: m68k and mips are
      two arches that do this.
      
      With this, some arch asm/module.h files can be deleted entirely and replaced
      with a generic-y marker in the arch Kbuild file.
      
      Additionally, I have removed the bits from m32r and score that handle the
      unsupported type of relocation record as that's now handled centrally.

      sock: Introduce the SO_PEEK_OFF sock option · ef64a54f
      Pavel Emelyanov 提交于
      This one specifies where to start MSG_PEEK-ing queue data from. When
      set to negative value means that MSG_PEEK works as ususally -- peeks
      from the head of the queue always.
      
      When some bytes are peeked from queue and the peeking offset is non
      negative it is moved forward so that the next peek will return next
      portion of data.
      
      When non-peeking recvmsg occurs and the peeking offset is non negative
      is is moved backward so that the next peek will still peek the proper
      data (i.e. the one that would have been picked if there were no non
      peeking recv in between).
      
      The offset is set using per-proto opteration to let the protocol handle
      the locking issues and to check whether the peeking offset feature is
      supported by the protocol the socket belongs to.

      net: add wireless TX status socket option · 6e3e939f
      Johannes Berg 提交于
      The 802.1X EAPOL handshake hostapd does requires
      knowing whether the frame was ack'ed by the peer.
      Currently, we fudge this pretty badly by not even
      transmitting the frame as a normal data frame but
      injecting it with radiotap and getting the status
      out of radiotap monitor as well. This is rather
      complex, confuses users (mon.wlan0 presence) and
      doesn't work with all hardware.
      
      To get rid of that hack, introduce a real wifi TX
      status option for data frame transmissions.
      
      This works similar to the existing TX timestamping
      in that it reflects the SKB back to the socket's
      error queue with a SCM_WIFI_STATUS cmsg that has
      an int indicating ACK status (0/1).
      
      Since it is possible that at some point we will
      want to have TX timestamping and wifi status in a
      single errqueue SKB (there's little point in not
      doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
      to SO_EE_ORIGIN_TXSTATUS which can collect more
      than just the timestamp; keep the old constant
      as an alias of course. Currently the internal APIs
      don't make that possible, but it wouldn't be hard
      to split them up in a way that makes it possible.
      
      Thanks to Neil Horman for helping me figure out
      the functions that add the control messages.
