2022-07-19fs: Add missing umask strip in vfs_tmpfileYang Xu1-0/+2
All creation paths except for O_TMPFILE handle umask in the vfs directly if the filesystem doesn't support or enable POSIX ACLs. If the filesystem does then umask handling is deferred until posix_acl_create(). Because, O_TMPFILE misses umask handling in the vfs it will not honor umask settings. Fix this by adding the missing umask handling.

2022-07-19fs: add mode_strip_sgid() helperYang Xu2-4/+34
Add a dedicated helper to handle the setgid bit when creating a new file in a setgid directory. This is a preparatory patch for moving setgid stripping into the vfs. The patch contains no functional changes. Currently the setgid stripping logic is open-coded directly in inode_init_owner() and the individual filesystems are responsible for handling setgid inheritance. Since this has proven to be brittle as evidenced by old issues we uncovered over the last months (see [1] to [3] below) we will try to move this logic into the vfs.

2022-07-19KVM: selftests: Fix target thread to be migrated in rseq_testGavin Shan1-3/+5
In rseq_test, there are two threads, which are vCPU thread and migration worker separately. Unfortunately, the test has the wrong PID passed to sched_setaffinity() in the migration worker. It forces migration on the migration worker because zeroed PID represents the calling thread, which is the migration worker itself. It means the vCPU thread is never enforced to migration and it can migrate at any time, which eventually leads to failure as the following logs show. host# uname -r 5.19.0-rc6-gavin+ host# # cat /proc/cpuinfo | grep processor | tail -n 1 processor : 223 host# pwd /home/gavin/sandbox/linux.main/tools/testing/selftests/kvm host# for i in `seq 1 100`; do \ echo "--------> $i"; ./rseq_test; done --------> 1 --------> 2 --------> 3 --------> 4 --------> 5 --------> 6 ==== Test Assertion Failure ==== rseq_test.c:265: rseq_cpu == cpu pid=3925 tid=3925 errno=4 - Interrupted system call 1 0x0000000000401963: main at rseq_test.c:265 (discriminator 2) 2 0x0000ffffb044affb: ?? ??:0 3 0x0000ffffb044b0c7: ?? ??:0 4 0x0000000000401a6f: _start at ??:? rseq CPU = 4, sched CPU = 27 Fix the issue by passing correct parameter, TID of the vCPU thread, to sched_setaffinity() in the migration worker.

2022-07-19KVM: s390: pv: destroy the configuration before its memoryClaudio Imbrenda1-3/+3
Move the Destroy Secure Configuration UVC before the loop to destroy the memory. If the protected VM has memory, it will be cleaned up and made accessible by the Destroy Secure Configuration UVC. The struct page for the relevant pages will still have the protected bit set, so the loop is still needed to clean that up. Switching the order of those two operations does not change the outcome, but it is significantly faster.

2022-07-19s390/mm: KVM: pv: when tearing down, try to destroy protected pagesClaudio Imbrenda1-3/+16
When ptep_get_and_clear_full is called for a mm teardown, we will now attempt to destroy the secure pages. This will be faster than export. In case it was not a teardown, or if for some reason the destroy page UVC failed, we try with an export page, like before.

2022-07-19KVM: s390: pv: add mmu_notifierClaudio Imbrenda4-0/+39
Add an mmu_notifier for protected VMs. The callback function is triggered when the mm is torn down, and will attempt to convert all protected vCPUs to non-protected. This allows the mm teardown to use the destroy page UVC instead of export. Also make KVM select CONFIG_MMU_NOTIFIER, needed to use mmu_notifiers.
