| * libbb: optionally honour libc provided SIGRTMIN/SIGRTMAX in get_signum()Rasmus Villemoes2018-10-311-23/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an application documents that it responds such and such to SIGRTMIN+n, that almost always means with respect to the libc-provided SIGRTMIN. Hence I disagree with the "more correct" in commit 7b276fc17594. In any case, this is rather unfortunate: 36 34 (the first shell is bash). We probably can't change default behaviour after 7 years, but at least we can provide a config option. We avoid a little code generation (repeated calls to __libc_current_sigrtmin) by stashing SIGRTMIN/SIGRTMAX in local variables, but it does cost ~50 bytes. The next patch serves as penance for that.

| * remove_file: don't call rmdir if remove_file return failureChen Yu2018-09-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When deleting a directory, the directory should not be removed if the file in the subdirectory fails to be deleted. Background information: When I tested the kernel using LTP (linux-test-project).I found the mv command have some issue. The LTP test case use the mv command to move the directory t1 in the cgroup file system to the /tmp directory. becase files in the cgroup file system are not allowed to be removed. so the mv reported "Permission denied", but I used the ls command to view the results and found that the directory t1 had been removed from the cgroup file system. For the same test case, I used the mv tool in the GNU coreutils, and the directory t1 will not be removed. the following testcase use busybox mv: / # mount -t cgroup -o cpu cgroup /cpu / # cd /cpu /cpu # mkdir -p t1 /cpu # ls cgroup.clone_children cpu.cfs_period_us cpu.stat t1 cgroup.procs cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior cpu.shares release_agent /cpu # mv t1 /tmp mv: can't remove 't1/cgroup.procs': Operation not permitted mv: can't remove 't1/cpu.cfs_period_us': Operation not permitted mv: can't remove 't1/cpu.stat': Operation not permitted mv: can't remove 't1/cpu.shares': Operation not permitted mv: can't remove 't1/cpu.cfs_quota_us': Operation not permitted mv: can't remove 't1/tasks': Operation not permitted mv: can't remove 't1/notify_on_release': Operation not permitted mv: can't remove 't1/cgroup.clone_children': Operation not permitted /cpu # ls cgroup.clone_children cpu.cfs_period_us cpu.stat cgroup.procs cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior cpu.shares release_agent /cpu # This patch fixed it, don't call rmdir if remove_file return failure, and under certain file systems, the mv could work normally.

The fix is: we don't even _want_ to restore scrit fds, we are perfectly fine with them being moved.

| | | | | | | | | | | | | | | | | | Commit f7c592f6d "win32: exclude termios code" excluded some code to handle line input when stdin or stdout aren't ttys. It turns out that this is required when 'busybox sh -i' is run from an MSYS2 shell. See GitHub issue #115. Revert this part of the commit.
