|
||||
|
||||
Add the __inet_pton_length helper function.
|
||||
* resolv/resolv-internal.h (__inet_pton_length): Declare.
|
||||
* resolv/inet_pton (__inet_pton_length): Rename from __inet_pton.
|
||||
Add length argument.
|
||||
(__inet_pton): New function.
|
||||
(inet_pton4): Add length argument.
|
||||
(hex_digit_value): New function.
|
||||
(inet_pton6): Add length argument. Call hex_digit_value. Use
|
||||
memmove and memset to fill :: gap.
|
||||
* resolv/Makefile (tests, tsts-static, tests-internal): Add
|
||||
tst-inet_pton.
|
||||
* resolv/tst-inet_pton.c: New file.
|
||||
* support/Makefile (libsupport-routines): Add xmprotect.
|
||||
* support/xunistd.h (xmprotect): Declare.
|
||||
* support/xmprotect.c: New file.
