2024-01-16Move c_src dirs back to toplevelKent Overstreet
We just wanted c sourcefiles out of the top level, not c source directories. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-16move Rust sources to top level, C sources into c_srcThomas Bertschinger
This moves the Rust sources out of rust_src/ and into the top level. Running the bcachefs executable out of the development tree is now: $ ./target/release/bcachefs command or $ cargo run --profile release -- command instead of "./bcachefs command". Building and installing is still: $ make && make install Signed-off-by: Thomas Bertschinger <tahbertschinger@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-10kill bd_buffered_fdKent Overstreet
this gets us back down to a single fd for opening block devices, which means we can use O_EXCL. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-10kill bd_sync_fdKent Overstreet
not needed with pwritev2(.., RWF_SYNC), and perhaps we can get down to one fd and then use O_EXCL for block devices. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-12-09bcachefs-tools: Guard the __struct_group() #define in kernel.hChris Webb
Our include/linux/byteorder.h uses the system <asm/byteorder.h> because we don't provide our own in include/asm. This then pulls in system <linux/stddef.h> which defines __struct_group. That definition collides with the unconditional #define __struct_group in our local include/linux/kernel.h, provoking preprocessor warnings.

2023-12-09bcachefs-tools: Use sysinfo(2) directly to implement si_meminfo()Chris Webb
Use a single sysinfo(2) call to fill out struct sysinfo instead of multiple libc sysconf(3) requests, which will only make sysinfo(2) calls internally anyway. This also enables us to access other struct sysinfo fields, not just the three filled-out previously. As we provide our own definition of struct sysinfo in include/linux/mm.h to match the kernel, which is not guaranteed to align with the definition libc provides in <sys/sysinfo.h>, use syscall(SYS_sysinfo, ...) directly instead of the libc wrapper.

prior to this patch, on certain platforms (ie: armv7l), compilation fails due to atomic64_sub_return_release not being defined here. Ensure that the atomics header is pulled in, and ensure that it is available in all cases, regardless of whether ATOMIC64_SPINLOCK is defined.

2023-09-19bcachefs-tools: fix endian problems between bit spinlocks and futexesBrian Foster
bcachefs format on a big-endian (s390x) machine crashes down in the rhashtable code imported from the kernel. The reason this occurs lies within the rht_lock() -> bit_spin_lock() code, the latter of which casts bitmaps down to 32-bits to satisfy the requirements of the futex interface. The specific problem here is that a 64 -> 32 bit cast doesn't refer to the lower 8 bytes on a big endian machine, which means setting bit number 0 in the 32-bit map actually corresponds to bit 32 in the 64-bit map. The rhashtable code specifically uses bit zero of the bucket pointer for exclusion and uses native bitops elsewhere (i.e. __rht_ptr()) to identify NULL pointers. If bit 32 of the pointer is set by the locking code instead of bit 0, an otherwise NULL pointer looks like a non-NULL value and results in a segfault. The bit spinlock code imported by the kernel is originally intended to work with unsigned long. The kernel code is able to throttle the cpu directly when under lock contention, while the userspace implementation relies on the futex primitives to emulate reliable blocking. Since the futex interface introduces the 32-bit requirement, isolate the associated userspace hack to that particular code. Restore the native bitmap behavior of the bit spinlock code to address the rhashtable problem described above. Since this is not compatible with the futex interface, create a futex wrapper specifically to convert the native bitmap type to a 32-bit virtual address and mask value for the purposes of waiting/waking when under lock contention.
