      net: fix a kernel infoleak in x25 module · 79e48650
      Kangjie Lu 提交于
      Stack object "dte_facilities" is allocated in x25_rx_call_request(),
      which is supposed to be initialized in x25_negotiate_facilities.
      However, 5 fields (8 bytes in total) are not initialized. This
      object is then copied to userland via copy_to_user, thus infoleak
      occurs.

      ravb: Add missing free_irq() call to ravb_close() · 7fa816b9
      Geert Uytterhoeven 提交于
      When reopening the network device on ra7795/salvator-x, e.g. after a
      DHCP timeout:
      
          IP-Config: Reopening network devices...
          genirq: Flags mismatch irq 139. 00000000 (eth0:ch24:emac) vs. 00000000 (eth0:ch24:emac)
          ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch24:emac
          IP-Config: Failed to open eth0
          IP-Config: No network devices available
      
      The "mismatch" is due to requesting an IRQ that is already in use,
      while IRQF_PROBE_SHARED wasn't set.
      
      However, the real cause is that ravb_close() doesn't release the R-Car
      Gen3-specific secondary IRQ.
      
      Add the missing free_irq() call to fix this.

      uapi glibc compat: fix compile errors when glibc net/if.h included before linux/if.h · 4a91cb61
      Mikko Rapeli 提交于
      glibc's net/if.h contains copies of definitions from linux/if.h and these
      conflict and cause build failures if both files are included by application
      source code. Changes in uapi headers, which fixed header file dependencies to
      include linux/if.h when it was needed, e.g. commit 1ffad83d, made the
      net/if.h and linux/if.h incompatibilities visible as build failures for
      userspace applications like iproute2 and xtables-addons.
      
      This patch fixes compile errors when glibc net/if.h is included before
      linux/if.h:
      
      ./linux/if.h:99:21: error: redeclaration of enumerator ‘IFF_NOARP’

      ./linux/if.h:100:23: error: redeclaration of enumerator ‘IFF_PROMISC’
      
      The cases where linux/if.h is included before net/if.h need a similar fix in
      the glibc side, or the order of include files can be changed userspace
      code as a workaround.
      
      This change was tested in x86 userspace on Debian unstable with
      scripts/headers_compile_test.sh:
      
      $ make headers_install && \
        cd usr/include && ../../scripts/headers_compile_test.sh -l -k
      ...

      compiler-gcc: require gcc 4.8 for powerpc __builtin_bswap16() · 8634de6d
      Josh Poimboeuf 提交于
      gcc support for __builtin_bswap16() was supposedly added for powerpc in
      gcc 4.6, and was then later added for other architectures in gcc 4.8.
      
      However, Stephen Rothwell reported that attempting to use it on powerpc
      in gcc 4.6 fails with:
      
        lib/vsprintf.c:160:2: error: initializer element is not constant
        lib/vsprintf.c:160:2: error: (near initialization for 'decpair[0]')
        lib/vsprintf.c:160:2: error: initializer element is not constant
        lib/vsprintf.c:160:2: error: (near initialization for 'decpair[1]')
        ...
      
      I'm not entirely sure what those errors mean, but I don't see them on
      gcc 4.8.  So let's consider gcc 4.8 to be the official starting point
      for __builtin_bswap16().
      
      Arnd Bergmann adds:
       "I found the commit in gcc-4.8 that replaced the powerpc-specific
        implementation of __builtin_bswap16 with an architecture-independent
        one.  Apparently the powerpc version (gcc-4.6 and 4.7) just mapped to
        the lhbrx/sthbrx instructions, so it ended up not being a constant,
        though the intent of the patch was mainly to add support for the
        builtin to x86:
      
          https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52624
      
        has the patch that went into gcc-4.8 and more information."
