* hurd: [!__USE_MISC] Do not #undef BSD macros in ioctlsSamuel Thibault2023-12-021-0/+2
| | | | | When e.g. including termios.h first and then sys/ioctl.h, without e.g. _BSD_SOURCE, the latter would #undef e.g. ECHO, without defining it.
* hurd: Make error_t an int in C++Samuel Thibault2023-08-081-0/+6
| | | | | | | Making error_t defined to enum __error_t_codes conveniently makes the debugger print symbolic values, but in C++ int is not interoperable with enum __error_t_codes, leading to C++ application build issues, so let's revert error_t to int in C++.

* hurd: Rework generating errno.hSamuel Thibault2023-08-061-24/+0
| | | | | We only need to give to gawk the headers that actually define error numbers, so let's rather filter out the other included headers early.
* hurd: Implement MAP_EXCLSergey Bugaev2023-07-031-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MAP_FIXED is defined to silently replace any existing mappings at the address range being mapped over. This, however, is a dangerous, and only rarely desired behavior. Various Unix systems provide replacements or additions to MAP_FIXED: * SerenityOS and Linux provide MAP_FIXED_NOREPLACE. If the address space already contains a mapping in the requested range, Linux returns EEXIST. SerenityOS returns ENOMEM, however that is a bug, as the MAP_FIXED_NOREPLACE implementation is intended to be compatible with Linux. * FreeBSD provides the MAP_EXCL flag that has to be used in combination with MAP_FIXED. It returns EINVAL if the requested range already contains existing mappings. This is directly analogous to the O_EXCL flag in the open () call. * DragonFly BSD, NetBSD, and OpenBSD provide MAP_TRYFIXED, but with different semantics. DragonFly BSD returns ENOMEM if the requested range already contains existing mappings. NetBSD does not return an error, but instead creates the mapping at a different address if the requested range contains mappings. OpenBSD behaves the same, but also notes that this is the default behavior even without MAP_TRYFIXED (which is the case on the Hurd too). Since the Hurd leans closer to the BSD side, add MAP_EXCL as the primary API to request the behavior of not replacing existing mappings. Declare MAP_FIXED_NOREPLACE and MAP_TRYFIXED as aliases of (MAP_FIXED|MAP_EXCL), so any existing software that checks for either of those macros will pick them up automatically. For compatibility with Linux, return EEXIST if a mapping already exists. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-Id: <20230625231751.404120-5-bugaevc@gmail.com>

* hurd: rule out some mach headers when generating errno.hSamuel Thibault2023-05-111-3/+0
| | | | | | | | | | While mach/kern_return.h happens to pull mach/machine/kern_return.h, mach/machine/boolean.h, and mach/machine/vm_types.h (and realpath-ing them exposes the machine-specific machine symlink content), those headers do not actually define anything machine-specific for the content of errno.h. So we can just rule out these machine-specific from the dependency comment.
* hurd 64bit: Make dev_t word typeSamuel Thibault2023-05-021-1/+1
| | | | | | | dev_t are 64bit on Linux ports, so better increase their size on 64bit Hurd. It happens that this helps with BZ 23084 there: st_dev has type fsid_t (quad) and is specified by POSIX to have type dev_t. Making dev_t 64bit makes these match.
* hurd 64bit: Fix flock fields typesSamuel Thibault2023-05-012-27/+47
| | | | | | | The standards want l_type and l_whence to be short ints, see BZ 23081. We can leave them ints on i386 for ABI compatibility, but avoid hitting the issue on 64bit.

* hurd: Implement MSG_CMSG_CLOEXECSergey Bugaev2023-04-241-1/+4
| | | | | | | | | | | | | | | This is a new flag that can be passed to recvmsg () to make it atomically set the CLOEXEC flag on all the file descriptors received using the SCM_RIGHTS mechanism. This is useful for all the same reasons that the other XXX_CLOEXEC flags are useful: namely, it provides atomicity with respect to another thread of the same process calling (fork and then) exec at the same time. This flag is already supported on Linux and FreeBSD. The flag's value, 0x40000, is choosen to match FreeBSD's.

* hurd: Implement MAP_32BITSergey Bugaev2023-04-241-0/+1
| | | | | | | | | | | | | | | | | | | | This is a flag that can be passed to mmap () to request that the mapping being established should be located in the lower 2 GB area of the address space, so only the lower 31 (not 32) bits can be set in its address, and the address can be represented as a 32-bit integer without truncating it. This flag is intended to be compatible with Linux, FreeBSD, and Darwin flags of the same name. Out of those systems, it appears Linux and FreeBSD take MAP_32BIT to mean "map 31 bit", whereas Darwin allows the 32nd bit to be set in the address as well. The Hurd follows Linux and FreeBSD behavior. Unlike on those systems, on the Hurd MAP_32BIT is defined on all supported architectures (which currently are only i386 and x86_64).

* Move libc_freeres_ptrs and libc_subfreeres to hidden/weak functionsAdhemerval Zanella Netto2023-03-271-1/+0
| | | | | | | | | | | | | | | | | | | | They are both used by __libc_freeres to free all library malloc allocated resources to help tooling like mtrace or valgrind with memory leak tracking. The current scheme uses assembly markers and linker script entries to consolidate the free routine function pointers in the RELRO segment and to be freed buffers in BSS. This patch changes it to use specific free functions for libc_freeres_ptrs buffers and call the function pointer array directly with call_function_static_weak. It allows the removal of both the internal macros and the linker script sections. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* hurd: Implement SHM_ANONSergey Bugaev2023-02-011-0/+25
| | | | | | | | | | | | | | | This adds a special SHM_ANON value that can be passed into shm_open () in place of a name. When called in this way, shm_open () will create a new anonymous shared memory file. The file will be created in the same way that other shared memory files are created (i.e., under /dev/shm/), except that it is not given a name and therefore cannot be reached from the file system, nor by other calls to shm_open (). This is accomplished by utilizing O_TMPFILE. This is intended to be compatible with FreeBSD's API of the same name.

* hurd: Implement O_TMPFILESergey Bugaev2023-02-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a flag that causes open () to create a new, unnamed file in the same filesystem as the given directory. The file descriptor can be simply used in the creating process as a temporary file, or shared with children processes via fork (), or sent over a Unix socket. The file can be left anonymous, in which case it will be deleted from the backing file system once all copies of the file descriptor are closed, or given a permanent name with a linkat () call, such as the following: int fd = open ("/tmp", O_TMPFILE | O_RDWR, 0700); /* Do something with the file... */ linkat (fd, "", AT_FDCWD, "/tmp/filename", AT_EMPTY_PATH); In between creating the file and linking it to the file system, it is possible to set the file content, mode, ownership, author, and other attributes, so that the file visibly appears in the file system (perhaps replacing another file) atomically, with all of its attributes already set up. The Hurd support for O_TMPFILE directly exposes the dir_mkfile RPC to user programs. Previously, dir_mkfile was used by glibc internally, in particular for implementing tmpfile (), but not exposed to user programs through a Unix-level API. O_TMPFILE was initially introduced by Linux. This implementation is intended to be compatible with the Linux implementation, except that the O_EXCL flag is not given the special meaning when used together with O_TMPFILE, unlike on Linux.

| | | | | | | | | | | | | | | | | The inline and library functions that the CMSG_NXTHDR macro may expand to increment the pointer to the header before checking the stride of the increment against available space.

* Set default __TIMESIZE default to 64Adhemerval Zanella2021-12-231-0/+20

* io: Refactor close_range and closefromAdhemerval Zanella2021-11-241-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that Hurd implementis both close_range and closefrom (f2c996597d), we can make close_range() a base ABI, and make the default closefrom() implementation on top of close_range(). The generic closefrom() implementation based on __getdtablesize() is moved to generic close_range(). On Linux it will be overriden by the auto-generation syscall while on Hurd it will be a system specific implementation. The closefrom() now calls close_range() and __closefrom_fallback(). Since on Hurd close_range() does not fail, __closefrom_fallback() is an empty static inline function set by__ASSUME_CLOSE_RANGE. The __ASSUME_CLOSE_RANGE also allows optimize Linux __closefrom_fallback() implementation when --enable-kernel=5.9 or higher is used. Finally the Linux specific tst-close_range.c is moved to io and enabled as default. The Linuxism and CLOSE_RANGE_UNSHARE are guarded so it can be built for Hurd (I have not actually test it). Checked on x86_64-linux-gnu, i686-linux-gnu, and with a i686-gnu build.
* hurd: Implement close_range and closefromSergey Bugaev2021-11-071-0/+34
| | | | | | | | | | | | | | | | | | The close_range () function implements the same API as the Linux and FreeBSD syscalls. It operates atomically and reliably. The specified upper bound is clamped to the actual size of the file descriptor table; it is expected that the most common use case is with last = UINT_MAX. Like in the Linux syscall, it is also possible to pass the CLOSE_RANGE_CLOEXEC flag to mark the file descriptors in the range cloexec instead of acually closing them. Also, add a Hurd version of the closefrom () function. Since unlike on Linux, close_range () cannot fail due to being unuspported by the running kernel, a fallback implementation is never necessary.

Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h.

* Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella2018-06-261-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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}. Checked on x86_64-linux-gnu and i686-linux-gnu.
