uClibc thread-safety analysis
Things that are still known to be needed for thread safety:
getgrgid_r <not implemented, required by SuSv3>
getgrnam_r <not implemented, required by SuSv3>
Things that might be nice, but are not required:
gethostent_r <desired, but not required for SuSv3>
getnetbyaddr_r <desired, but not required for SuSv3>
getnetent_r <desired, but not required for SuSv3>
getnetbyname_r <desired, but not required for SuSv3>
getprotobynumber_r <desired, but not required for SuSv3>
getprotoent_r <desired, but not required for SuSv3>
getprotobyname_r <desired, but not required for SuSv3>
getnetbyaddr_r <desired, but not required for SuSv3>
getnetbyname_r <desired, but not required for SuSv3>
getnetent_r <desired, but not required for SuSv3>
getprotobynumber_r <desired, but not required for SuSv3>
getprotoent_r <desired, but not required for SuSv3>
getprotobyname_r <desired, but not required for SuSv3>
Functions that use static data and may still need locking:
--------------------------------------------------------------------
libc/inet/rpc/rpc_thread.c:
__rpc_thread_variables is currently disabled, since thread
local storage seems to not be correctly specified as
weak functions.
--------------------------------------------------------------------
unistd/getpass.c:
static char buf[PWD_BUFFER_SIZE];
getpass <fix required> <---
NOTE: This function returns a pointer to a static data structure.
This seems like it requires an _r version of this function. Glibc
does the same thing. Oops! So much for thread-safe glibc!
--------------------------------------------------------------------
unistd/sysconf.c:
static long int ret_vals[_UCLIBC_SYSCONF_NUM_VALID_ARGS];
find_or_add_in_table <fix required?> <---
main <fix required?> <---
NOTE: I'm not sure if this needs to be made reentrant...
