* posix: Add glob64 with 64-bit time_t supportAdhemerval Zanella2021-06-151-0/+6
| | | | | | | | | | | The glob might pass a different stat struct for gl_stat and gl_lstat when GLOB_ALTDIRFUNC is used. This requires add a new 64-bit time version that also uses 64-bit time stat functions. Checked on i686-linux-gnu and x86_64-linux-gnu.

* posix: Add compat glob symbol to not follow dangling symbolsAdhemerval Zanella2017-09-251-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch follows commit 5554304f0 (posix: Allow glob to match dangling symlinks [BZ #866]) by adding a compat symbol that follow previous semantic of not following dangling symlinks and thus avoiding call gl_lstat with GLOB_ALTDIRFUNC. It avoids failure with old binaries that not set the alternate function pointer for lstat (GNUmake for instance). The following scenario, for instance, fails with current GNUmake because glibc will access unitialized memory when calling gl_lstat: $ cat src/t/t.c int main () { return 0; } $ cat Makefile SRC = $(wildcard src/*/t.c) OBJ = $(patsubst src/%.c, obj/%.o, $(SRC)) prog: $(OBJ) $(CC) $(CFLAGS) $(LDFLAGS) $(LIBS) $(OBJ) -o prog obj/%.o: src/%.c $(CC) $(CFLAGS) -c $< -o $@ $ make This works as expected with the patch applied. Since it is for generic ABI, default compat symbols are added with override for Linux due LFS. Now we have two compat symbols for glob on Linux: 1. sysdeps/unix/sysv/linux/oldglob.c which implements glob64 with the old dirent layout. For this implementation I also set it to not follow dangling symlinks (which is the safest path). 2. sysdeps/unix/sysv/linux/glob{64}-lstat-compat.c which implements the compat symbol for dangling symlinks. As for generic glob, the implementation uses XSTAT_IS_XSTAT64 to define whether both __glob_lstat_compat and __glob64_lstat_compat should be different implementations. For archictures that define XSTAT_IS_XSTAT64, __glob_lstat_compat is aliased to __glob64_lstat_compat. 3. sysdeps/unix/sysv/linux/alpha/oldglob.c with a different glob_t layout. As for 1. this patch changes it to not follow dangling symlinks. The patch also bumps _GNU_GLOB_INTERFACE_VERSION to 2 to advertise the new semantic. On GNUmake, for instance, it will force to it use its internal glob implementation instead and avoiding triggering the same failure on builds against newer GLIBCs. Checked on x86_64-linux-gnu and i686-linux-gnu. I also checked with a build against the major ABIs required to check for the abilist. The changes should also work on gnulib (I run gnulib-tool.py check glob and it shown no regressions).

* posix: Consolidate Linux glob implementationAdhemerval Zanella2017-09-081-0/+28
This patch consolidates the glob implementation. The main changes are: * On Linux all implementation now uses the default one at sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception of alpha (which requires specific versioning) and s390-32 (which different than other 32 bits ports it does not add a compat one symbol for 2.1 version). * The default implementation uses XSTAT_IS_XSTAT64 to define whether both glob{free} and glob{free}64 should be different implementations. For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias to glob{free}64. * Move i386 olddirent.h header to Linux default directory, since it is the only header with this name and it is shared among different architectures (and used on compat glob symbol as well). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. * sysdeps/unix/sysv/linux/arm/glob64.c: Remove file. * sysdeps/unix/sysv/linux/i386/glob64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/glob64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/glob64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/glob64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/glob.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/globfree.c: Likewise. * sysdeps/wordsize-64/glob.c: Likewise. * sysdeps/wordsize-64/glob64.c: Likewise. * sysdeps/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/glob.c: New file. * sysdeps/unix/sysv/linux/glob64.c: Likewise. * sysdeps/unix/sysv/linux/globfree.c: Likewise. * sysdeps/unix/sysv/linux/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/oldglob.c [SHLIB_COMPAT]: Also adds !GLOB_NO_OLD_VERSION as an extra condition. * sysdeps/unix/sysv/linux/i386/alphasort64.c: Include olddirent.h using relative path instead of absolute one. * sysdeps/unix/sysv/linux/i386/getdents64.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/i386/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/i386/olddirent.h: Move to ... * sysdeps/unix/sysv/linux//olddirent.h: ... here.
