TPE forbids mmap('rwx') files opened for writes: fd = open (a_file_in_tmp, O_RDWR); mmap (..., PROT_READ | PROT_WRITE | PROT_EXEC, fd); while allows anonymous RWX mappings: mmap (...MAP_ANONYMOUS , PROT_READ | PROT_WRITE | PROT_EXEC, -1); Thanks to klondike for finding it out. The result of a horrible typo. (unreleased yet) upstream also has the patch: http://github.com/atgreen/libffi/commit/eaf444eabc4c78703c0f98ac0197b1619c1b1bef >--------------------------------------------------------------- libffi/ghc.mk | 2 ++ libffi/libffi.selinux-detection-3.0.8.patch | 15 +++++++++++++++ 2 files changed, 17 insertions(+), 0 deletions(-) diff --git a/libffi/ghc.mk b/libffi/ghc.mk index 6dfef8f..080c43f 100644 --- a/libffi/ghc.mk +++ b/libffi/ghc.mk @@ -107,6 +107,8 @@ $(libffi_STAMP_CONFIGURE): cat ghc-tarballs/libffi/libffi*.tar.gz | $(GZIP_CMD) -d | { cd libffi && $(TAR_CMD) -xf - ; } mv libffi/libffi-* libffi/build chmod +x libffi/ln + # don't report nonselinux systems as selinux + cd libffi/build && "$(PATCH_CMD)" -p0 < ../libffi.selinux-detection-3.0.8.patch # Because -Werror may be in SRC_CC_OPTS/SRC_LD_OPTS, we need to turn # warnings off or the compilation of libffi might fail due to warnings diff --git a/libffi/libffi.selinux-detection-3.0.8.patch b/libffi/libffi.selinux-detection-3.0.8.patch new file mode 100644 index 0000000..a919f28 --- /dev/null +++ b/libffi/libffi.selinux-detection-3.0.8.patch @@ -0,0 +1,15 @@ +src/closures.c (selinux_enabled_check): Fix strncmp usage bug. + +http://github.com/atgreen/libffi/commit/eaf444eabc4c78703c0f98ac0197b1619c1b1bef + +--- src/closures.c ++++ src/closures.c +@@ -146,7 +146,7 @@ + p = strchr (p + 1, ' '); + if (p == NULL) + break; +- if (strncmp (p + 1, "selinuxfs ", 10) != 0) ++ if (strncmp (p + 1, "selinuxfs ", 10) == 0) + { + free (buf); + fclose (f); _______________________________________________ Cvs-ghc mailing list Cvs-ghc@haskell.org http://www.haskell.org/mailman/listinfo/cvs-ghc
