* posix: Add compat glob symbol to not follow dangling symbolsAdhemerval Zanella2017-09-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Sync glob with gnulib [BZ #1062]Adhemerval Zanella2017-09-081-6/+0

The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures. Also the code simplification leads to not macro simplification (not need for NO_GLOB_PATTERN_P anymore). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #1062] * posix/Makefile (routines): Add globfree, globfree64, and glob_pattern_p. * posix/flexmember.h: New file. * posix/glob_internal.h: Likewise. * posix/glob_pattern_p.c: Likewise. * posix/globfree.c: Likewise. * posix/globfree64.c: Likewise. * sysdeps/gnu/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/alpha/globfree.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/oldglob.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/globfree.c: Likewise. * sysdeps/wordsize-64/globfree.c: Likewise. * sysdeps/wordsize-64/globfree64.c: Likewise. * posix/glob.c (HAVE_CONFIG_H): Use !_LIBC instead. [NDEBUG): Remove comments. (GLOB_ONLY_P, _AMIGA, VMS): Remove define. (dirent_type): New type. Use uint_fast8_t not uint8_t, as C99 does not require uint8_t. (DT_UNKNOWN, DT_DIR, DT_LNK): New macros. (struct readdir_result): Use dirent_type. Do not define skip_entry unless it is needed; this saves a byte on platforms lacking d_ino. (readdir_result_type, readdir_result_skip_entry): New functions, replacing ... (readdir_result_might_be_symlink, readdir_result_might_be_dir): these functions, which were removed. This makes the callers easier to read. All callers changed. (D_INO_TO_RESULT): Now empty if there is no d_ino. (size_add_wrapv, glob_use_alloca): New static functions. (glob, glob_in_dir): Check for size_t overflow in several places, and fix some size_t checks that were not quite right. Remove old code using SHELL since Bash no longer uses this. (glob, prefix_array): Separate MS code better. (glob_in_dir): Remove old Amiga and VMS code. (globfree, __glob_pattern_type, __glob_pattern_p): Move to separate files. (glob_in_dir): Do not rely on undefined behavior in accessing struct members beyond their bounds. Use a flexible array member instead (link_stat): Rename from link_exists2_p and return -1/0 instead of 0/1. Caller changed. (glob): Fix memory leaks. * posix/glob64 (globfree64): Move to separate file. * sysdeps/gnu/glob64.c (NO_GLOB_PATTERN_P): Remove define. (globfree64): Remove hidden alias. * sysdeps/unix/sysv/linux/Makefile (sysdeps_routines): Add oldglob. * sysdeps/unix/sysv/linux/alpha/glob.c (__new_globfree): Move to separate file. * sysdeps/unix/sysv/linux/i386/glob64.c (NO_GLOB_PATTERN_P): Remove define. Move compat code to separate file. * sysdeps/wordsize-64/glob.c (globfree): Move definitions to separate file.
