Add multi-arch capable 'fbsd_make_corefile_notes' variant This creates a new version of the FreeBSD core file note generation logic in the new target-dependent file "fbsd-tdep.c". The new version is mostly copied from "fbsd-nat.c", but uses the iterator instead of regset_from_core_section and defines fbsd_make_corefile_notes as a gdbarch method instead of a target method. Consecutive architecture-dependent changes exploit the new version, migrating away from the target method. When all FreeBSD targets are changed, the target method can go away. gdb/ChangeLog: * fbsd-tdep.c: New file. * fbsd-tdep.h: New file. * Makefile.in (ALL_TARGET_OBS): Add fbsd-tdep.o. (HFILES_NO_SRCDIR): Add fbsd-tdep.h. (ALLDEPFILES): Add fbsd-tdep.c.

/* Target-dependent code for FreeBSD, architecture independent.
Update copyright year range in header of all files managed by GDB This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.

Add support for 'info proc files' on FreeBSD core dumps. Walk the list of struct kinfo_file objects in the NT_FREEBSD_PROCSTAT_FILES core dump note outputting a description of each open file descriptor. For sockets, the local and remote socket addresses are displayed in place of the file name field. For UNIX local domain sockets, only a single address is displayed since most UNIX sockets only have one valid address and printing both pathnames could be quite long. The output format was somewhat inspired by the output of the "procstat -f" command on FreeBSD, but with a few less details and some fields were condensed. gdb/ChangeLog: * fbsd-tdep.c (KF_FLAGS, KF_OFFSET, KF_VNODE_TYPE, KF_SOCK_DOMAIN) (KF_SOCK_TYPE, KF_SOCK_PROTOCOL, KF_SA_LOCAL, KF_SA_PEER) (KINFO_FILE_TYPE_SOCKET, KINFO_FILE_TYPE_PIPE) (KINFO_FILE_TYPE_FIFO, KINFO_FILE_TYPE_KQUEUE) (KINFO_FILE_TYPE_CRYPTO, KINFO_FILE_TYPE_MQUEUE) (KINFO_FILE_TYPE_SHM, KINFO_FILE_TYPE_SEM, KINFO_FILE_TYPE_PTS) (KINFO_FILE_TYPE_PROCDESC, KINFO_FILE_FD_TYPE_ROOT) (KINFO_FILE_FD_TYPE_JAIL, KINFO_FILE_FD_TYPE_TRACE) (KINFO_FILE_FD_TYPE_CTTY, KINFO_FILE_FLAG_READ) (KINFO_FILE_FLAG_WRITE, KINFO_FILE_FLAG_APPEND) (KINFO_FILE_FLAG_ASYNC, KINFO_FILE_FLAG_FSYNC) (KINFO_FILE_FLAG_NONBLOCK, KINFO_FILE_FLAG_DIRECT) (KINFO_FILE_FLAG_HASLOCK, KINFO_FILE_FLAG_EXEC) (KINFO_FILE_VTYPE_VREG, KINFO_FILE_VTYPE_VDIR) (KINFO_FILE_VTYPE_VCHR, KINFO_FILE_VTYPE_VLNK) (KINFO_FILE_VTYPE_VSOCK, KINFO_FILE_VTYPE_VFIFO, FBSD_AF_UNIX) (FBSD_AF_INET, FBSD_AF_INET6, FBSD_SOCK_STREAM, FBSD_SOCK_DGRAM) (FBSD_SOCK_SEQPACKET, FBSD_IPPROTO_ICMP, FBSD_IPPROTO_TCP) (FBSD_IPPROTO_UDP, FBSD_IPPROTO_SCTP): New defines.

Support 'info proc' for FreeBSD process core dumps. - Command line arguments are obtained from the pr_psargs[] array saved in the NT_PRPSINFO note. - The 'cwd' and 'exe' values are obtained from the per-process file descriptor table stored in the NT_PROCSTAT_FILES core note. - 'mappings' is implemented by walking the array of VM map entries stored in the NT_PROCSTAT_VMMAP core note. - 'status' output is generated by outputting fields from the first structure stored in the NT_PROCSTAT_PROC core note. - 'stat' is aliased to 'status'. gdb/ChangeLog: * fbsd-tdep.c (KVE_STRUCTSIZE, KVE_START, KVE_END, KVE_OFFSET) (KVE_FLAGS, KVE_PROTECTION, KVE_PATH, KINFO_VME_PROT_READ) (KINFO_VME_PROT_WRITE, KINFO_VME_PROT_EXEC, KINFO_VME_FLAG_COW) (KINFO_VME_FLAG_NEEDS_COPY, KINFO_VME_FLAG_NOCOREDUMP) (KINFO_VME_FLAG_SUPER, KINFO_VME_FLAG_GROWS_UP) (KINFO_VME_FLAG_GROWS_DOWN, KF_STRUCTSIZE, KF_TYPE, KF_FD) (KF_PATH, KINFO_FILE_TYPE_VNODE, KINFO_FILE_FD_TYPE_CWD) (KINFO_FILE_FD_TYPE_TEXT, SIG_WORDS, struct kinfo_proc_layout) (kinfo_proc_layout_32, kinfo_proc_layout_i386) (kinfo_proc_layout_64, fbsd_vm_map_entry_flags) (fbsd_core_info_proc_mappings, fbsd_core_vnode_path) (fbsd_core_fetch_timeval, fbsd_print_sigset) (fbsd_core_info_proc_status, fbsd_core_info_proc): New.

Add a helper function to resolve TLS variable addresses for FreeBSD. The fbsd_get_thread_local_address function accepts the base address of a thread's DTV array and the base address of an object file's link map and uses this to compute a TLS variable's address. FreeBSD architectures use an architecture-specific method to determine the address of the DTV array pointer and call this helper function to perform the rest of the address calculation. * fbsd-tdep.c (fbsd_pspace_data_handle): New variable.
