| Subject: [PATCH] uapi: fix linux/packet_diag.h userspace compilation error |
| |
| commit 745cb7f8a5de0805cade3de3991b7a95317c7c73 upstream. |
| |
| Replace MAX_ADDR_LEN with its numeric value to fix the following |
| linux/packet_diag.h userspace compilation error: |
| |
| /usr/include/linux/packet_diag.h:67:17: error: 'MAX_ADDR_LEN' undeclared here (not in a function) |
| __u8 pdmc_addr[MAX_ADDR_LEN]; |
| |
| This is not the first case in the UAPI where the numeric value |
| of MAX_ADDR_LEN is used instead of symbolic one, uapi/linux/if_link.h |
| already does the same: |
| |
| $ grep MAX_ADDR_LEN include/uapi/linux/if_link.h |
| __u8 mac[32]; /* MAX_ADDR_LEN */ |
| |
| There are no UAPI headers besides these two that use MAX_ADDR_LEN. |
