* src: Use gnu17 as the default C standard for userland instead of gnu99Minsoo Choo2025-02-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | Tracking newer versions of C (and C++) permits assuming newer language features in the base system. Some C11 extensions are already used in the base system but implemented on top of GNU C extensions such as _Alignas and _Static_assert. In some cases the fallback versions in cdefs.h are more limited than the native C11 extensions. Even though C11 is the next major version of C, C17 is chosen instead since C17 does not add new features to C but merely fixes defects in C11. It is also well supported by a wide range of clang (7.0.0+) and GCC (8.1+) versions. Along with changing the default, this change also removes explicit requests for c11 via the CSTD variable in various Makefiles. Libraries and binaries for ZFS continue to use c99.

* newfs_msdos: align to multiple of cluster size by defaultStefan Eßer2024-06-062-20/+9
| | | | | | | | | | | | | | | | | | | | | A previous commit aligned the start of the data area to a multiple of the VM page size, in order to prevent extra buffers to be allocated (which failed for 64 KB cluster size without this alignment). Since a dependency on PAGE_SIZE caused compatibility issues, the alignment was made conditional on this macro being defined, in the previous commit. This lead to different behavior of this program when built on FreeBSD vs. Linux (which does not define PAGE_SIZE). This commit removes any use of PAGE_SIZE and instead always aligns the start of the data area to a multiple of the cluster size. The -A option is now implied, unless overridden by a specific number of reserved sectors with the -r option.

* newfs_msdos: align data area to VM page boundary by defaultStefan Eßer2024-06-022-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | Without alignment, the data area will not be aligned with the buffer cache, leading to overhead, higher write multiplication on SSD devices and issues with very large cluster sizes (see PR 277414). The -A option used to align the start of the root directory to a multiple of the cluster size, which happens to align the start of the data area with a buffer page boundary in case of large clusters and the default number of directory entries (512 entries requiring 16 KB for FAT12 or FAT16, FAT32 puts the root directory into the data area). This commit aligns the start of the data area with the page size, if neither -A nor -r is used. It changes -A to align the start of the data area (end of the root directory) to a multiple of the cluster size, since this is the alignment that prevents write multiplication due to clusters crossing erase block boundaries of a SSD device. The -r option is unchanged and will prevent any automatic alignment from occuring. Approved by: kib MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D45436
* newfs_msdos.8: example for specific cluster sizeAlexander Ziaee2024-01-221-2/+8
| | | | | | | | | | The usual use case in 2024 for newfs_msdosfs is creating filesystems on SD cards for older hardware. In most tutorials, they call the cluster size "allocation size". Therefore, add a small note next to cluster size that it is also called allocation size, and add an example for how to do this.

* Allow bootstrapping makefs on older FreeBSD hosts and Linux/macOSAlex Richardson2020-01-271-11/+44
| | | | | | | | | | | | | | | | | | | | | | In order to do so we need to install the msdosfs headers to the bootstrap sysroot and avoid includes of kernel headers that may not exist on every host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs on FreeBSD 11+ as well as Linux and macOS. We also have to avoid using the IO_SYNC macro since that may not be available. In makefs it is only used to switch between calling bwrite() and bdwrite() which both call the same function. Therefore we can simply always call bwrite(). For our CheriBSD builds we always bootstrap makefs by setting LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary from the build tree to create a bootable disk image.

| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.
