2022-07-29bpf: Fix test_progs -j error with fentry/fexit testsSong Liu
When multiple threads are attaching/detaching fentry/fexit programs to the same trampoline, we may call register_fentry on the same trampoline twice: register_fentry(), unregister_fentry(), then register_fentry again. This causes ftrace_set_filter_ip() for the same ip on tr->fops twice, which leaves duplicated ip in tr->fops. The extra ip is not cleaned up properly on unregister and thus causes failures with further register in register_ftrace_direct_multi(): register_ftrace_direct_multi() { ... for (i = 0; i < size; i++) { hlist_for_each_entry(entry, &hash->buckets[i], hlist) { if (ftrace_find_rec_direct(entry->ip)) goto out_unlock; } } ... } This can be triggered with parallel fentry/fexit tests with test_progs: ./test_progs -t fentry,fexit -j Fix this by resetting tr->fops in ftrace_set_filter_ip(), so that there will never be duplicated entries in tr->fops.

2022-07-29RDMA/srpt: Fix a use-after-freeBart Van Assche
Change the LIO port members inside struct srpt_port from regular members into pointers. Allocate the LIO port data structures from inside srpt_make_tport() and free these from inside srpt_make_tport(). Keep struct srpt_device as long as either an RDMA port or a LIO target port is associated with it. This patch decouples the lifetime of struct srpt_port (controlled by the RDMA core) and struct srpt_port_id (controlled by LIO).

2022-07-29drm/amd/display: Fix a compilation failure on PowerPC caused by FPU codeRodrigo Siqueira
We got a report from Stephen/Michael that the PowerPC build was failing with the following error: ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o This error happened because of the function optc3_set_vrr_m_const. This function expects a double as a parameter in a code that is not allowed to have FPU operations. After further investigation, it became clear that optc3_set_vrr_m_const was never invoked, so we can safely drop this function and fix the ld issue.

2022-07-29mm/hmm: fault non-owner device private entriesRalph Campbell
If hmm_range_fault() is called with the HMM_PFN_REQ_FAULT flag and a device private PTE is found, the hmm_range::dev_private_owner page is used to determine if the device private page should not be faulted in. However, if the device private page is not owned by the caller, hmm_range_fault() returns an error instead of calling migrate_to_ram() to fault in the page. For example, if a page is migrated to GPU private memory and a RDMA fault capable NIC tries to read the migrated page, without this patch it will get an error. With this patch, the page will be migrated back to system memory and the NIC will be able to read the data.

2022-07-29page_alloc: fix invalid watermark check on a negative valueJaewon Kim
There was a report that a task is waiting at the throttle_direct_reclaim. The pgscan_direct_throttle in vmstat was increasing. This is a bug where zone_watermark_fast returns true even when the free is very low. The commit f27ce0e14088 ("page_alloc: consider highatomic reserve in watermark fast") changed the watermark fast to consider highatomic reserve. But it did not handle a negative value case which can be happened when reserved_highatomic pageblock is bigger than the actual free. If watermark is considered as ok for the negative value, allocating contexts for order-0 will consume all free pages without direct reclaim, and finally free page may become depleted except highatomic free. Then allocating contexts may fall into throttle_direct_reclaim. This symptom may easily happen in a system where wmark min is low and other reclaimers like kswapd does not make free pages quickly. Handle the negative case by using MIN.

The send_signal/send_signal_tracepoint is pretty flaky, with at least one failure in every ten runs on a few attempts I've tried it: > test_send_signal_common:PASS:pipe_c2p 0 nsec > test_send_signal_common:PASS:pipe_p2c 0 nsec > test_send_signal_common:PASS:fork 0 nsec > test_send_signal_common:PASS:skel_open_and_load 0 nsec > test_send_signal_common:PASS:skel_attach 0 nsec > test_send_signal_common:PASS:pipe_read 0 nsec > test_send_signal_common:PASS:pipe_write 0 nsec > test_send_signal_common:PASS:reading pipe 0 nsec > test_send_signal_common:PASS:reading pipe error: size 0 0 nsec > test_send_signal_common:FAIL:incorrect result unexpected incorrect result: actual 48 != expected 50 > test_send_signal_common:PASS:pipe_write 0 nsec > #139/1 send_signal/send_signal_tracepoint:FAIL The reason does not appear to be a correctness issue in the strict sense. Rather, we merely do not receive the signal we are waiting for within the provided timeout. Let's bump the timeout by a factor of ten. With that change I have not been able to reproduce the failure in 150+ iterations. I am also sneaking in a small simplification to the test_progs test selection logic.
