It replaces the internal usage of __{f,l}xstat{at}{64} with the __{f,l}stat{at}{64}. It should not change the generate code since sys/stat.h explicit defines redirections to internal calls back to xstat* symbols. Checked with a build for all affected ABIs.

It's possible that although __OFF_T_MATCHES_OFF64_T is defined the included the relevent header file. This results in a io/tst-lockf failure for RV32 by calling the non 64-bit version of lockf.

2020-08-19Add new STATX_* constants from Linux 5.8 to bits/statx-generic.h.Joseph Myers1-0/+3
This patch adds the new STATX_MNT_ID, STATX_ATTR_MOUNT_ROOT and STATX_ATTR_DAX macros from Linux 5.8 to glibc's bits/statx-generic.h. (As with previous such changes, this only does anything if glibc is being used with old kernel headers.) A comment in the Linux kernel headers indicates that STATX_ALL is deliberately not being changed. Tested for x86_64.

2020-02-18Move implementation of <file_change_detection.h> into a C fileFlorian Weimer4-31/+150
file_change_detection_for_stat partially initialize struct file_change_detection in some cases, when the size member alone determines the outcome of all comparisons. This results in maybe-uninitialized compiler warnings in case of sufficiently aggressive inlining. Once the implementation is moved into a separate C file, this kind of inlining is no longer possible, so the compiler warnings are gone.

2019-02-15io: Consolidate lockf implementationAdhemerval Zanella4-84/+177
With internal fcntl64 internal (commit 06ab719d), it is possible to consolidate lockf implementation by using the LFS fcntl interface instead of using arch and system-specific implementations. For Linux, the i386 implementation is used as generic implementation by replacing the direct syscall with fcntl64 call. The LFS symbol alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid the duplicate symbol (instead of overriding the implementation with an empty file). For Hurd lockf64 semantic is changed: previous generic lockf64 implementation returned EOVERFLOW if LEN input is larger than 32-bit off_t. However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64, and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t inputs).

2018-07-18Avoid insecure usage of tmpnam in tests.Joseph Myers1-9/+3
Various glibc testcases use tmpnam in ways subject to race conditions (generate a temporary file name, then later open that file without O_EXCL). This patch fixes those tests to use mkstemp - generally a minimal local fix to use mkstemp instead of tmpnam, rather than a larger fix to use other testsuite infrastructure for temporary files. The unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the event of a race (it's generating a name for use with mkdir rather than for a file to be opened for writing).

2018-06-26Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella4-2/+55
This patch fixes the OFD ("file private") locks for architectures that support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and F_{SET,GET}L{W}K64 expects a flock64 argument and when using old F_OFD_* flags with a non LFS flock argument the kernel might interpret the underlying data wrongly. Kernel idea originally was to avoid using such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS semantic as default it is possible to provide the functionality and avoid the bogus struct kernel passing by adjusting the struct manually for the required flags. The idea follows other LFS interfaces that provide two symbols: 1. A new LFS fcntl64 is added on default ABI with the usual macros to select it for FILE_OFFSET_BITS=64. 2. The Linux non-LFS fcntl use a stack allocated struct flock64 for F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided struct. 3. Keep a compat symbol with old broken semantic for architectures that do not define __OFF_T_MATCHES_OFF64_T. So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will aliased to fcntl and no adjustment would be required. So to actually use F_OFD_* with LFS support the source must be built with LFS support (_FILE_OFFSET_BITS=64). Also F_OFD_SETLKW command is handled a cancellation point, as for F_SETLKW{64}.

2018-06-12Avoid cancellable I/O primitives in ld.so.Zack Weinberg1-0/+6
Neither the <dlfcn.h> entry points, nor lazy symbol resolution, nor initial shared library load-up, are cancellation points, so ld.so should exclusively use I/O primitives that are not cancellable. We currently achieve this by having the cancellation hooks compile as no-ops when IS_IN(rtld); this patch changes to using exclusively _nocancel primitives in the source code instead, which makes the intent clearer and significantly reduces the amount of code compiled under IS_IN(rtld) as well as IS_IN(libc) -- in particular, elf/Makefile no longer thinks we require a copy of unwind.c in rtld-libc.a. (The older mechanism is preserved as a backstop.) The bulk of the change is splitting up the files that define the _nocancel I/O functions, so they don't also define the variants that *are* cancellation points; after which, the existing logic for picking out the bits of libc that need to be recompiled as part of ld.so Just Works. I did this for all of the _nocancel functions, not just the ones used by ld.so, for consistency. fcntl was a little tricky because it's only a cancellation point for certain opcodes (F_SETLKW(64), which can block), and the existing __fcntl_nocancel wasn't applying the FCNTL_ADJUST_CMD hook, which strikes me as asking for trouble, especially as the only nontrivial definition of FCNTL_ADJUST_CMD (for powerpc64) changes F_*LK* opcodes. To fix this, fcntl_common moves to fcntl_nocancel.c along with __fcntl_nocancel, and changes its name to the extern (but hidden) symbol __fcntl_nocancel_adjusted, so that regular fcntl can continue calling it. __fcntl_nocancel now applies FCNTL_ADJUST_CMD; so that both both fcntl.c and fcntl_nocancel.c can see it, the only nontrivial definition moves from sysdeps/u/s/l/powerpc/powerpc64/fcntl.c to .../powerpc64/sysdep.h and becomes entirely a macro, instead of a macro that calls an inline function. The nptl version of libpthread also changes a little, because its "compat-routines" formerly included files that defined all the _nocancel functions it uses; instead of continuing to duplicate them, I exported the relevant ones from libc.so as GLIBC_PRIVATE. Since the Linux fcntl.c calls a function defined by fcntl_nocancel.c, it can no longer be used from libpthread.so; instead, introduce a custom forwarder, pt-fcntl.c, and export __libc_fcntl from libc.so as GLIBC_PRIVATE. The nios2-linux ABI doesn't include a copy of vfork() in libpthread, and it was handling that by manipulating libpthread-routines in .../linux/nios2/Makefile; it is cleaner to do what other such ports do, and have a pt-vfork.S that defines no symbols. Right now, it appears that Hurd does not implement _nocancel I/O, so sysdeps/generic/not-cancel.h will forward everything back to the regular functions. This changed the names of some of the functions that sysdeps/mach/hurd/dl-sysdep.c needs to interpose. * elf/dl-load.c, elf/dl-misc.c, elf/dl-profile.c, elf/rtld.c * sysdeps/unix/sysv/linux/dl-sysdep.c Include not-cancel.h.

2018-01-12linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]Dmitry V. Levin2-1/+67
Currently getcwd(3) can succeed without returning an absolute path because the underlying getcwd syscall, starting with linux commit v2.6.36-rc1~96^2~2, may succeed without returning an absolute path. This is a conformance issue because "The getcwd() function shall place an absolute pathname of the current working directory in the array pointed to by buf, and return buf". This is also a security issue because a non-absolute path returned by getcwd(3) causes a buffer underflow in realpath(3). Fix this by checking the path returned by getcwd syscall and falling back to generic_getcwd if the path is not absolute, effectively making getcwd(3) fail with ENOENT. The error code is chosen for consistency with the case when the current directory is unlinked. [BZ #22679] CVE-2018-1000001 * sysdeps/unix/sysv/linux/getcwd.c (__getcwd): Fall back to generic_getcwd if the path returned by getcwd syscall is not absolute. * io/tst-getcwd-abspath.c: New test. * io/Makefile (tests): Add tst-getcwd-abspath.

2017-12-15Fix testing with read-only source directory.Joseph Myers1-0/+2
Three tests fail with a read-only source directory because they try to write into the source directory. None of these write into it in a way that should actually be problematic for concurrent builds sharing the same writable source directory, but avoiding any writing into the source directory (from testing, or from building glibc if the source timestamps are properly ordered) is still a good idea, as being able to build with read-only sources helps make sure there isn't anything that could cause problems for concurrent builds. This patch changes the tests in question to use either /tmp or the build directory to write their temporary files (or to test O_TMPFILE, as applicable). Tested for x86_64. * io/Makefile (tst-open-tmpfile-ARGS): New variable. * posix/tst-mmap-offset.c (fname): Use /tmp. * stdlib/tst-setcontext3.sh (tempfile): Use ${objpfx}.

2017-08-31io: Remove internal_function attributeFlorian Weimer2-27/+11
2017-08-18Consolidate non cancellable close callAdhemerval Zanella1-2/+2
This patch consolidates all the non cancellable close calls to use the __close_nocancel{_nostatus} identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE namespace. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * sysdeps/generic/not-cancel.h (close_not_cancel): Remove macro. (close_not_cancel_no_status): Likewise.
