Then we have the real one defined with another name, and set +as efi_set_variable@@LIBEFIVAR_0.24. Then to make there actually be a +efi_set_variable symbol to link against, we create it as a weak alias. + +This is all completely absurd. + +Signed-off-by: Peter Jones <pjones@redhat.com> +--- + src/lib.c | 17 ++++++++++++----- + 1 file changed, 12 insertions(+), 5 deletions(-) + +diff --git a/src/lib.c b/src/lib.c +index 6a9b392..afa7d94 100644 +--- a/src/lib.c ++++ b/src/lib.c +@@ -49,7 +49,7 @@ _efi_set_variable(efi_guid_t guid, const char *name, uint8_t *data, + { + return ops->set_variable(guid, name, data, data_size, attributes, 0600); + } +-__asm__(".symver _efi_set_variable,_efi_set_variable@"); ++__asm__(".symver _efi_set_variable,_efi_set_variable@libefivar.so.0"); + + int + __attribute__((__nonnull__ (2, 3))) +@@ -59,17 +59,24 @@ _efi_set_variable_variadic(efi_guid_t guid, const char *name, uint8_t *data, + { + return ops->set_variable(guid, name, data, data_size, attributes, 0600); + } +-__asm__(".symver _efi_set_variable_variadic,efi_set_variable@"); ++__asm__(".symver _efi_set_variable_variadic,efi_set_variable@libefivar.so.0"); + + int + __attribute__((__nonnull__ (2, 3))) + __attribute__((__visibility__ ("default"))) +-efi_set_variable(efi_guid_t guid, const char *name, uint8_t *data, +- size_t data_size, uint32_t attributes, mode_t mode) ++_efi_set_variable_mode(efi_guid_t guid, const char *name, uint8_t *data, ++ size_t data_size, uint32_t attributes, mode_t mode) + { + return ops->set_variable(guid, name, data, data_size, attributes, mode); + } +-__asm__(".symver efi_set_variable,efi_set_variable@@LIBEFIVAR_0.24"); ++__asm__(".symver _efi_set_variable_mode,efi_set_variable@@LIBEFIVAR_0.24"); ++ ++int ++__attribute__((__nonnull__ (2, 3))) ++__attribute__((__visibility__ ("default"))) ++efi_set_variable(efi_guid_t guid, const char *name, uint8_t *data, ++ size_t data_size, uint32_t attributes, mode_t mode) ++ __attribute((weak, alias ("_efi_set_variable_mode"))); + + int + __attribute__((__nonnull__ (2, 3))) +-- +2.12.2 + |
