Merge bitcoin/bitcoin#23196: util: Make syscall sandbox compilable with kernel 4.4.0
ac402e749c91d40ce7066993f72f426b67196bd7 util: Conditionalize some syscalls in syscall name table (W. J. van der Laan)
64085b37f8d5c018372f013e925a725b67b527fc util: Add __NR_copy_file_range syscall constant for sandbox (W. J. van der Laan)
Pull request description:
Make the new syscall sandbox compilable with kernel 4.4.0.
This defines a further syscall constant `__NR_copy_file_range` to make sure all syscalls used in the profile are available even if not defined in the kernel headers.
Also, make a few syscalls optional in the syscall name table:
- `__NR_pkey_alloc`
- `__NR_pkey_free`
- `__NR_pkey_mprotect`
- `__NR_preadv2`
- `__NR_pwritev2`
