apr_strings: Provide apr_memzero_explicit() in APR.

2022-06-28T16:09:12+00:00

This function is handy outside apu_crypto usage, don't require users to link
to APU for the feature.

This commit moves the apr_crypto_memzero() implementation to apr_strings under
the apr_memzero_explicit() name, and replaces the calls to the former with the
latter, and apr_crypto_memzero() now calls apr_memzero_explicit() directly.

* include/apr_strings.h():
  Declare apr_memzero_explicit().

* strings/apr_strings.c():
  Implement apr_memzero_explicit() by moving/renaming the code from apu_crypto.

* crypto/apr_crypto.c(apr_crypto_memzero):
  Fall back to apr_memzero_explicit().

* crypto/apr_crypto.c(crypto_clear):
  Use apr_memzero_explicit() instead of apr_crypto_memzero().

* crypto/apr_crypto_prng.c(cprng_cleanup, cprng_stream_bytes,
                           apr_crypto_prng_reseed, cprng_bytes,
                           apr_crypto_prng_rekey, apr_crypto_prng_after_fork):
  Use apr_memzero_explicit() instead of apr_crypto_memzero().

* crypto/apr_md4.c(MD4Transform):
  Use apr_memzero_explicit() instead of apr_crypto_memzero().

encoding: Better check inputs of apr_{encode,decode}_* functions.

2022-06-27T15:26:09+00:00

Check that the given sources can be encoded without overflowing.

Return APR_EINVAL if the given "slen" is negative, APR_NOTFOUND if "dest" is
not NULL and "src" is NULL, or APR_ENOSPC if "dest" is NULL and the source
length (based on "slen" or APR_ENCODE_STRING) is too big to encode.
 
* include/private/apr_encode_private.h():
  Rename ENCODE_TO_ASCII() and ENCODE_TO_NATIVE() to respectively TO_ASCII()
  and TO_ENCODE(), and make them return an unsigned char.

* encoding/apr_escape.c():
  Use the new TO_ASCII() and TO_NATIVE().

* encoding/apr_encode.c(apr_encode_*, apr_decode_*):
  Forbid negative "slen" but APR_ENCODE_STRING, and use apr_size_t arithmetics
  to check for overflows when encoding.
  When "dest" is NULL, "src" can be NULL too.
  Better check for trailing '='s or base16's APR_ENCODE_COLON ':' separators.
  Rename ENCODE_TO_ASCII and ENCODE_TO_NATIVE to their new names, and remove
  casts to (unsigned char) now unnecessary.

* include/apr_encode.h():
  Update dox about acceptable inputs and returned errors.

* test/testencode.c():
  Tests for error conditions.

atomic: Detect 32bit and 64bit atomic builtins separately.

2022-06-26T22:50:09+00:00

Some 32bit platforms provide 32bit but not 64bit atomics, detect and
distinctly set/use HAVE_ATOMIC_BUILTINS/HAVE_ATOMIC_BUILTINS64 and
USE_ATOMICS_BUILTINS/USE_ATOMICS_BUILTINS64.

These platforms NEED_ATOMICS_GENERIC64 as 64bit implementation.

* configure.in():
  Use stdint.h's uint{32,64}_t as atomic type for testing atomic builtins
  when available, otherwise "unsigned int" for 32bit testing and
  "unsigned long long" as 64bit.

* configure.in():
  AC_TRY_RUN each 32bit and 64bit type separately, the former determining
  HAVE_ATOMIC_BUILTINS and the latter HAVE_ATOMIC_BUILTINS64.

* include/arch/unix/apr_arch_atomic.h():
  Define USE_ATOMICS_BUILTINS64 when HAVE_ATOMIC_BUILTINS64, otherise
  define NEED_ATOMICS_GENERIC64

* include/arch/unix/apr_arch_atomic.h():
  Check defined(__powerpc__) for USE_ATOMICS_PPC.

* atomic/unix/builtins64.c():
  Implement for USE_ATOMICS_BUILTINS64 only.

BZ 63566.

* Improve detection of _Thread_local

2022-03-09T13:05:17+00:00

GCC < 4.9 reports __STDC_VERSION__ >= 201112 but does not implement
_Thread_local. Take care of this in the condition.

trunk.

poll: Follow up to r1897521: Clarify what APR_POLLEXCL means.

2022-01-27T14:20:36+00:00

This is to avoid the thundering herd issue when multiple threads/processes
poll on the same descriptor (usually listening/to-be-accept()ed descriptors).
