2017-09-25posix: Add compat glob symbol to not follow dangling symbolsAdhemerval Zanella1-24/+43
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).

2017-09-08posix: fix glob bugs with long login namesAdhemerval Zanella1-58/+30
Current glob implementation allows unlimited user name for home directory construction on GLOB_TILDE case. To accomplish it glob either construct a name on stack if size are small enough (based on current alloca_used) or in heap otherwise. This patch simplifies storage allocation by using the same scratch buffer for both get_rlogin_r and getpwnam_r. This also syncs with gnulib commit 064df0b (glob: fix bugs with long login names).

2017-09-08posix: Allow glob to match dangling symlinks [BZ #866]Adhemerval Zanella1-153/+86
This patch makes glob match dangling symlinks. Compared to other glob implementation (*BSD, bash, musl, and other shells as well), GLIBC seems the be the only one that does not match dangling symlinks. As for comment #5 in BZ #866, POSIX does not have any strict specification for dangling symlinks match and it is reasonable that trying to glob everything in a path should return all types of files (such as for a 'rm *'). Also, comment #7 shows even more example where GLIBC current behavior is unexepected. I avoided adding another GNU specific flag to set this behavior and instead make it the default. Although this change the semanthic from previous implementation, I think adding another compat symbol to be really unecessary as from aforementioned reasons (current behavior not defined in any standard, general idea of different implementation is to list dangling symbols). This also sync glob with gnulib commit fd1daf4 (glob: match dangling symlinks). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures.

2017-09-08posix: Sync glob with gnulib [BZ #1062]Adhemerval Zanella1-404/+370
This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). 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.

2016-04-29glob: Simplify the interface for the GLOB_ALTDIRFUNC callback gl_readdirFlorian Weimer1-21/+3
Previously, application code had to set up the d_namlen member if the target supported it, involving conditional compilation. After this change, glob will use the length of the string in d_name instead of d_namlen to determine the file name length. All glibc targets provide the d_type and d_ino members, and setting them as needed for gl_readdir is straightforward. Changing the behavior with regards to d_ino is left to a future cleanup.

2015-10-20Convert miscellaneous function definitions to prototype style.Joseph Myers1-5/+2
This patch converts various miscellaneous functions definitions in glibc, found with grep and not covered by my previous scripted conversions, from old-style K&R to prototype-style. These changes were made manually. This is not necessarily exhaustive as formatting variants may have prevented my grep from finding some such definitions. Regarding the changes to files from GMP, they may originally have been omitted when removing __STDC__ conditionals because of the files coming from another package, but (a) GMP no longer has __STDC__ conditionals there anyway and (b) we don't try to keep these files verbatim in sync with GMP (and there are licensing differences), so making the change to them in glibc seems reasonable.

2015-10-20Convert 113 more function definitions to prototype style (files with ↵Joseph Myers1-8/+3
assertions). This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

2015-06-12Fix getlogin_r namespace (bug 18527).Joseph Myers1-1/+1
Various functions in XPG4 bring in references to getlogin_r, which is not in XPG4; this is also a bug for some older POSIX versions which aren't yet covered by the linknamespace tests. This patch fixes this by making getlogin_r into a weak alias for __getlogin_r and using __getlogin_r as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18527] * login/getlogin_r.c (getlogin_r): Rename to __getlogin_r and define as weak alias of __getlogin_r.
