* glnx-dirfd: Add a rewinddir() wrapperwip/smcv/rewinddirSimon McVittie2021-04-222-0/+19
| | | | | | | | This is useful in the same situations rewinddir() is. My use-case right now is to remove some of the files from a directory, then go back through the directory removing symlinks that pointed to those files. Signed-off-by: Simon McVittie <smcv@collabora.com>

| * glnx_file_copy_at: Add GLNX_FILE_COPY_NOCHOWNJonathan Lebon2021-02-092-3/+7
|/ | | | | | | | | | In some contexts, we may want to copy a root-owned file but we're not running as root so we can't `fchown` it. (The case I'm interested in is actually a bit more obscure than this: running in a supermin VM as root, and wanting to copy a file we created onto a 9p mount where we don't have perms to `fchown`). Add a `GLNX_FILE_COPY_NOCHOWN` to handle this case.

| * Add GLNX_FILE_REPLACE_INCREASING_MTIMEreplace-increasing-mtimeAlexander Larsson2020-11-032-9/+37
|/ | | | | | | | | | | | | | This make replaced files have a strictly increasing st_mtime. The main usecase I have for this is to ensure the summary file mtime increases because the flatpak tests are failing due to the python httpd used in the tests rely on st_mtime for the http If-Modified-Since header. For the tests this breaks all the time since we're just doing a lot of summary updates. However, I can see this accidentally happening in the wild too, so i think its proper to always ensure the new summary is "newer", even though it means it will be timestamped slightly in the future. In practice this will not happen regularly, and the times it *does* happen we really do need it.

|/ | | | | | | | | | | | | | | | | | `glnx_open_anonymous_tmpfile` attempts to create an fd in `/var/tmp` regardless of the value of `$TMPDIR`. This is _usually_ okay, but can fail in some contexts, such as in the [NixOS][1] build environment, which doesn't have `/var` mapped at all. To avoid failing in this case, if the inner call to `glnx_open_anonymous_tmpfile_full` fails, we retrieve the value of `$TMPDIR` and try calling `glnx_open_anonymous_tmpfile_full` again with that directory instead. In the fast path (i.e. where `/var/tmp` exists), functionality is unchanged. [1]: https://nixos.org/

| * glnx-fdio: handle EOPNOTSUPP for copy_file_rangeJonathan Lebon2020-06-161-1/+1
|/ | | | | | | | | | | | | | | | When using `copy_file_range` to target a source and dest on the same NFS mount on some older kernel versions, it's possible that we can get `EOPNOTSUPP` e.g. if the NFS server doesn't support server-side copy. We hit this in the FCOS release pipeline where we run `ostree pull-local` to pull content between two repos on the same mount from inside an OpenShift cluster on top of RHEL7. Nowadays, it seems like the kernel itself falls back to a more generic version of `copy_file_range()` at least. Though to be compatible with older kernels, let's add `EOPNOTSUPP` to the list of errors we interpret as "cfr possibly available, but can't be done for this specific operation".

|/ | | | | | | | We don't modify this struct (if non-NULL), so it can be const. In particular, this is helpful if calling glnx_file_copy_at() from nftw() to implement the equivalent of `cp -a --reflink=auto`. Signed-off-by: Simon McVittie <smcv@collabora.com>

|/ / | | | | | | | | | | | | | | | | This is useful if you need the file to be on a particular filesystem. In particular, flatpak wants this to make tempfiles on /tmp for things we need to write during flatpak run, such as the libseccomp output fd. We've had "flatpak run" stop working in low disk situations without this, so its nice to be able to fix it.
