From e768c86ef442ef89004089a8a34ce5909ffb90f2 Mon Sep 17 00:00:00 2001 From: stratakis Date: Tue, 23 Jan 2018 16:11:24 +0100 Subject: bpo-32635: Fix a segfault when importing the crypt module with libxcrypt. (#5284) glibc is deprecating libcrypt in favor of libxcrypt, however python assumes that crypt.h will always be included. This change makes the header inclusion explicit when libxcrypt is present on the system. --- Include/Python.h | 3 +++ Misc/NEWS.d/next/Build/2018-01-23-15-33-40.bpo-32635.qHwIZy.rst | 2 ++ configure | 2 +- configure.ac | 2 +- pyconfig.h.in | 3 +++ 5 files changed, 10 insertions(+), 2 deletions(-) create mode 100644 Misc/NEWS.d/next/Build/2018-01-23-15-33-40.bpo-32635.qHwIZy.rst diff --git a/Include/Python.h b/Include/Python.h index dd595ea..1feb153 100644 --- a/Include/Python.h +++ b/Include/Python.h @@ -35,6 +35,9 @@ #ifdef HAVE_UNISTD_H #include #endif +#ifdef HAVE_CRYPT_H +#include +#endif /* For size_t? */ #ifdef HAVE_STDDEF_H diff --git a/Misc/NEWS.d/next/Build/2018-01-23-15-33-40.bpo-32635.qHwIZy.rst b/Misc/NEWS.d/next/Build/2018-01-23-15-33-40.bpo-32635.qHwIZy.rst new file mode 100644 index 0000000..d411890 --- /dev/null +++ b/Misc/NEWS.d/next/Build/2018-01-23-15-33-40.bpo-32635.qHwIZy.rst @@ -0,0 +1,2 @@ +Fix segfault of the crypt module when libxcrypt is provided instead of +libcrypt at the system. diff --git a/configure b/configure index a9b0ab9..5904b54 100755 --- a/configure +++ b/configure @@ -7682,7 +7682,7 @@ $as_echo "#define STDC_HEADERS 1" >>confdefs.h fi -for ac_header in asm/types.h conio.h direct.h dlfcn.h errno.h \ +for ac_header in asm/types.h crypt.h conio.h direct.h dlfcn.h errno.h \ fcntl.h grp.h \ ieeefp.h io.h langinfo.h libintl.h process.h pthread.h \ sched.h shadow.h signal.h stropts.h termios.h \ diff --git a/configure.ac b/configure.ac index 03b0f50..15ef872 100644 --- a/configure.ac +++ b/configure.ac @@ -2041,7 +2041,7 @@ dnl AC_MSG_RESULT($cpp_type) # checks for header files AC_HEADER_STDC -AC_CHECK_HEADERS(asm/types.h conio.h direct.h dlfcn.h errno.h \ +AC_CHECK_HEADERS(asm/types.h crypt.h conio.h direct.h dlfcn.h errno.h \ fcntl.h grp.h \ ieeefp.h io.h langinfo.h libintl.h process.h pthread.h \ sched.h shadow.h signal.h stropts.h termios.h \ diff --git a/pyconfig.h.in b/pyconfig.h.in index dd7c62b..fd5a0c3 100644 --- a/pyconfig.h.in +++ b/pyconfig.h.in @@ -140,6 +140,9 @@ /* Define to 1 if you have the `copysign' function. */ #undef HAVE_COPYSIGN +/* Define to 1 if you have the header file. */ +#undef HAVE_CRYPT_H + /* Define to 1 if you have the `ctermid' function. */ #undef HAVE_CTERMID -- cgit v0.12
