Hi all,
After merging the net-next tree, today's linux-next build (arm multi_v7_defconfig) failed like this:
In file included from <command-line>: In function 'tcp_struct_check', inlined from 'tcp_init' at net/ipv4/tcp.c:4703:2: include/linux/compiler_types.h:460:45: error: call to '__compiletime_assert_940' declared with attribute error: BUILD_BUG_ON failed: offsetof(struct tcp_sock, __cacheline_group_end__tcp_sock_write_txrx) - offsetofend(struct tcp_sock, __cacheline_group_begin__tcp_sock_write_txrx) > 92 460 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^ include/linux/compiler_types.h:441:25: note: in definition of macro '__compiletime_assert' 441 | prefix ## suffix(); \ | ^~~~~~ include/linux/compiler_types.h:460:9: note: in expansion of macro '_compiletime_assert' 460 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^~~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:39:37: note: in expansion of macro 'compiletime_assert' 39 | #define BUILD_BUG_ON_MSG(cond, msg) compiletime_assert(!(cond), msg) | ^~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:50:9: note: in expansion of macro 'BUILD_BUG_ON_MSG' 50 | BUILD_BUG_ON_MSG(condition, "BUILD_BUG_ON failed: " #condition) | ^~~~~~~~~~~~~~~~ include/linux/cache.h:108:9: note: in expansion of macro 'BUILD_BUG_ON' 108 | BUILD_BUG_ON(offsetof(TYPE, __cacheline_group_end__##GROUP) - \ | ^~~~~~~~~~~~ net/ipv4/tcp.c:4673:9: note: in expansion of macro 'CACHELINE_ASSERT_GROUP_SIZE' 4673 | CACHELINE_ASSERT_GROUP_SIZE(struct tcp_sock, tcp_sock_write_txrx, 92); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Presumably caused by commit
d2c3a7eb1afa ("tcp: more struct tcp_sock adjustments")
I have reverted that commit for today.
