2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2021-02-24Use make_tempname file descriptor in smart_renameAlan Modra1-14/+21
This patch makes use of the temp file descriptor in smart_rename rather than reopening the file. I don't believe there is a security issue in reopening the file, but this way is one less directory operation. The patch also attempts to preserve S_ISUID and S_ISGID.

2021-02-19binutils: Avoid renaming over existing filesSiddhesh Poyarekar1-86/+9
Renaming over existing files needs additional care to restore permissions and ownership, which may not always succeed. Additionally, other properties of the file such as extended attributes may be lost, making the operation flaky. For predictable results, resort to rename() only if the file does not exist, otherwise copy the file contents into the existing file. This ensures that no additional tricks are needed to retain file properties. This also allows dropping of the redundant set_times on the tmpfile in objcopy/strip since now we no longer rename over existing files. binutils/ * ar.c (write_archive): Remove TARGET_STAT. Adjust call to SMART_RENAME. * arsup.c (ar_save): Likewise. * objcopy (strip_main): Don't copy TMPFD. Don't set times on temporary file and adjust call to SMART_RENAME. (copy_main): Likewise. * rename.c [!S_ISLNK]: Remove definitions. (try_preserve_permissions): Remove function. (smart_rename): Remove FD, PRESERVE_DATES arguments. Use rename system call only if TO does not exist. * bucomm.h (smart_rename): Adjust declaration.

2020-12-07binutils: Make smart_rename safe tooSiddhesh Poyarekar1-31/+70
smart_rename is capable of handling symlinks by copying and it also tries to preserve ownership and permissions of files when they're overwritten during the rename. This is useful in objcopy where the file properties need to be preserved. However because smart_rename does this using file names, it leaves a race window between renames and permission fixes. This change removes this race window by using file descriptors from the original BFDs that were used to manipulate these files wherever possible. The file that is to be renamed is also passed as a file descriptor so that we use fchown/fchmod on the file descriptor, thus making sure that we only modify the file we have opened to write. Further, in case the file is to be overwritten (as is the case in ar or objcopy), the permissions that need to be restored are taken from the file descriptor that was opened for input so that integrity of the file status is maintained all the way through to the rename. binutils/ * rename.c * ar.c (write_archive) [!defined (_WIN32) || defined (__CYGWIN32__)]: Initialize TARGET_STAT and OFD to pass to SMART_RENAME. * arsup.c (ar_save) [defined (_WIN32) || defined (__CYGWIN32__)]: Likewise. * bucomm.h (smart_rename): Add new arguments to declaration. * objcopy.c (strip_main)[defined (_WIN32) || defined (__CYGWIN32__)]: Initialize COPYFD and pass to SMART_RENAME. (copy_main) [defined (_WIN32) || defined (__CYGWIN32__)]: Likewise. * rename.c (try_preserve_permissions): New function. (smart_rename): Use it and add new arguments.
