musl/src/network, branch v1.0.3 musl - an implementation of the standard library for Linux-based systems fix multiple validation issues in dns response label parsing 2014-06-06T21:57:37+00:00 Szabolcs Nagy nsz@port70.net 2014-06-05T20:32:42+00:00 309cfa4f2c3a5596a024d0bff7bba326382884b4 Due to an error introduced in commit fcc522c92335783293ac19df318415cd97fbf66b, checking of the remaining output buffer space was not performed correctly, allowing malformed input to write past the end of the buffer. In addition, the loop detection logic failed to account for the possibility of infinite loops with no output, which would hang the function. The output size is now limited more strictly so only names with valid length are accepted. (cherry picked from commit b3d9e0b94ea73c68ef4169ec82c898ce59a4e30a) 
Due to an error introduced in commit fcc522c92335783293ac19df318415cd97fbf66b,
checking of the remaining output buffer space was not performed correctly,
allowing malformed input to write past the end of the buffer.

In addition, the loop detection logic failed to account for the possibility
of infinite loops with no output, which would hang the function.

The output size is now limited more strictly so only names with valid length
are accepted.

remove some dummy "ent" function aliases that duplicated real ones 2014-06-06T21:57:36+00:00 Rich Felker dalias@aerifal.cx 2014-06-04T08:39:34+00:00 8daa49cdfd5c74fb8edf931394be11c62b915e52 the service and protocol functions are defined also in other files, and the protocol ones are actually non-nops elsewhere, so the weak definitions in ent.c could have prevented the strong definitions from getting pulled in and used in some static programs.

add fallback emulation for accept4 on old kernels 2014-02-22T03:25:26+00:00 Rich Felker dalias@aerifal.cx 2014-02-22T03:25:26+00:00 dc01e2cbfb290198c03514fe51ed32c1098b774f the other atomic FD_CLOEXEC interfaces (dup3, pipe2, socket) already had such emulation in place. the justification for doing the emulation here is the same as for the other functions: it allows applications to simply use accept4 rather than having to have their own fallback code for ENOSYS/EINVAL (which one you get is arch-specific!) and there is no reasonable way an application could benefit from knowing the operation is emulated/non-atomic since there is no workaround at the application level for non-atomicity (that is the whole reason these interfaces were added).
