mmc: fix compilation of user API

2020-06-11T07:21:38+00:00

commit 83fc5dd57f86c3ec7d6d22565a6ff6c948853b64 upstream. The definitions of MMC_IOC_CMD and of MMC_IOC_MULTI_CMD rely on MMC_BLOCK_MAJOR: #define MMC_IOC_CMD _IOWR(MMC_BLOCK_MAJOR, 0, struct mmc_ioc_cmd) #define MMC_IOC_MULTI_CMD _IOWR(MMC_BLOCK_MAJOR, 1, struct mmc_ioc_multi_cmd) However, MMC_BLOCK_MAJOR is defined in linux/major.h and linux/mmc/ioctl.h did not include it.

uapi: fix linux/if_pppol2tp.h userspace compilation errors

commit a725eb15db80643a160310ed6bcfd6c5a6c907f2 upstream. Because of interface limitations, provided by libc cannot be included after , therefore any header that includes cannot be included after . Change uapi/linux/l2tp.h, the last uapi header that includes , to include and instead of and use __SOCK_SIZE__ instead of sizeof(struct sockaddr) the same way as uapi/linux/in.h does, to fix linux/if_pppol2tp.h userspace compilation errors like this: In file included from /usr/include/linux/l2tp.h:12:0, from /usr/include/linux/if_pppol2tp.h:21, /usr/include/netinet/in.h:31:8: error: redefinition of 'struct in_addr' Fixes: 47c3e7783be4 ("net: l2tp: deprecate PPPOL2TP_MSG_* in favour of L2TP_MSG_*") Signed-off-by: Dmitry V.

net: l2tp: deprecate PPPOL2TP_MSG_* in favour of L2TP_MSG_*

commit 47c3e7783be4e142b861d34b5c2e223330b05d8a upstream. PPPOL2TP_MSG_* and L2TP_MSG_* are duplicates, and are being used interchangeably in the kernel, so let's standardize on L2TP_MSG_* internally, and keep PPPOL2TP_MSG_* defined in UAPI for compatibility.

uapi glibc compat: fix outer guard of net device flags enum

2020-04-02T17:02:34+00:00

[ Upstream commit efc45154828ae4e49c6b46f59882bfef32697d44 ] Fix a wrong condition preventing the higher net device flags IFF_LOWER_UP etc to be defined if net/if.h is included before linux/if.h. The comment makes it clear the intention was to allow partial definition with either parts. This fixes compilation of userspace programs trying to use IFF_LOWER_UP, IFF_DORMANT or IFF_ECHO.
