uapi glibc compat: fix compilation when !__USE_MISC in glibc

2016-06-24T17:22:00Z

[ Upstream commit f0a3fdca794d1e68ae284ef4caefe681f7c18e89 ] These structures are defined only if __USE_MISC is set in glibc net/if.h headers, ie when _BSD_SOURCE or _SVID_SOURCE are defined.

uapi glibc compat: fix compile errors when glibc net/if.h included before linux/if.h

2016-05-10T01:29:31Z

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:98:23: error: redeclaration of enumerator ‘IFF_RUNNING’ ./linux/if.h:97:26: error: redeclaration of enumerator ‘IFF_NOTRAILERS’ ./linux/if.h:96:27: error: redeclaration of enumerator ‘IFF_POINTOPOINT’ ./linux/if.h:95:24: error: redeclaration of enumerator ‘IFF_LOOPBACK’ ./linux/if.h:94:21: error: redeclaration of enumerator ‘IFF_DEBUG’ ./linux/if.h:93:25: error: redeclaration of enumerator ‘IFF_BROADCAST’ ./linux/if.h:92:19: error: redeclaration of enumerator ‘IFF_UP’ ./linux/if.h:252:8: error: redefinition of ‘struct ifconf’ ./linux/if.h:203:8: error: redefinition of ‘struct ifreq’ ./linux/if.h:169:8: error: redefinition of ‘struct ifmap’ ./linux/if.h:107:23: error: redeclaration of enumerator ‘IFF_DYNAMIC’ ./linux/if.h:106:25: error: redeclaration of enumerator ‘IFF_AUTOMEDIA’ ./linux/if.h:105:23: error: redeclaration of enumerator ‘IFF_PORTSEL’ ./linux/if.h:104:25: error: redeclaration of enumerator ‘IFF_MULTICAST’ ./linux/if.h:103:21: error: redeclaration of enumerator ‘IFF_SLAVE’ ./linux/if.h:102:22: error: redeclaration of enumerator ‘IFF_MASTER’ ./linux/if.h:101:24: error: redeclaration of enumerator ‘IFF_ALLMULTI’ ./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.

macsec: key identifier is 128 bits, not 64

2016-05-09T04:09:01Z

The MACsec standard mentions a key identifier for each key, but doesn't specify anything about it, so I arbitrarily chose 64 bits. IEEE 802.1X-2010 specifies MKA (MACsec Key Agreement), and defines the key identifier to be 128 bits (96 bits "member identifier" + 32 bits "key number").

byteswap: try to avoid __builtin_constant_p gcc bug

2016-05-06T00:38:53Z

This is another attempt to avoid a regression in wwn_to_u64() after that started using get_unaligned_be64(), which in turn ran into a bug on gcc-4.9 through 6.1. The regression got introduced due to the combination of two separate workarounds (commits e3bde9568d99: "include/linux/unaligned: force inlining of byteswap operations" and ef3fb2422ffe: "scsi: fc: use get/put_unaligned64 for wwn access") that each try to sidestep distinct problems with gcc behavior (code growth and increased stack usage). Unfortunately after both have been applied, a more serious gcc bug has been uncovered, leading to incorrect object code that discards part of a function and causes undefined behavior. As part of this problem is how __builtin_constant_p gets evaluated on an argument passed by reference into an inline function, this avoids the use of __builtin_constant_p() for all architectures that set CONFIG_ARCH_USE_BUILTIN_BSWAP. Most architectures do not set ARCH_SUPPORTS_OPTIMIZED_INLINING, which means they probably do not suffer from the problem in the qla2xxx driver, but they might still run into it elsewhere. Both of the original workarounds were only merged in the 4.6 kernel, and the bug that is fixed by this patch should only appear if both are there, so we probably don't need to backport the fix. On the other hand, it works by simplifying the code path and should not have any negative effects.

Pull asm-generic syscall fix from Arnd Bergmann: "My last pull request for asm-generic had just one patch that added two new system calls to asm/unistd.h, but unfortunately it turned out to be wrong, pointing arch/tile compat mode at the native handlers rather than the compat ones. This was spotted by Yury Norov, who is working on ILP32 mode for arch/arm64, which would have the same problem when merged. This fixes the table to use the correct compat syscalls, like the other 64-bit architectures do. I'll try to find the time to come up with a solution that prevents this problem from happening again, by allowing all future system calls to just get added in a single file for use by all architectures" * tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: use compat version for preadv2 and pwritev2

asm-generic: use compat version for preadv2 and pwritev2

2016-05-04T22:42:20Z

Compat architectures that does not use generic unistd (mips, s390), declare compat version in their syscall tables for preadv2 and pwritev2. Generic unistd syscall table should do it as well. [arnd: this initially slipped through the review and an incorrect patch got merged. arch/tile/ is the only architecture that could be affected for their 32-bit compat mode, every other architecture we support today is fine.] Signed-off-by: Yury Norov Signed-off-by: Arnd Bergmann
