2022-08-10Merge branch 'fixes for bpf map iterator'Alexei Starovoitov
Hou Tao says: ==================== From: Hou Tao <houtao1@huawei.com> Hi, The patchset constitues three fixes for bpf map iterator: (1) patch 1~4: fix user-after-free during reading map iterator fd It is possible when both the corresponding link fd and map fd are closed bfore reading the iterator fd. I had squashed these four patches into one, but it was not friendly for stable backport, so I break these fixes into four single patches in the end. Patch 7 is its testing patch. (2) patch 5: fix invalidity check for values in sk local storage map Patch 8 adds two tests for it. (3) patch 6: reject sleepable program for non-resched map iterator Patch 9 add a test for it. Please check the individual patches for more details. And comments are always welcome.

2022-08-10bpf: Only allow sleepable program for resched-able iteratorHou Tao
When a sleepable program is attached to a hash map iterator, might_fault() will report "BUG: sleeping function called from invalid context..." if CONFIG_DEBUG_ATOMIC_SLEEP is enabled. The reason is that rcu_read_lock() is held in bpf_hash_map_seq_next() and won't be released until all elements are traversed or bpf_hash_map_seq_stop() is called. Fixing it by reusing BPF_ITER_RESCHED to indicate that only non-sleepable program is allowed for iterator without BPF_ITER_RESCHED. We can revise bpf_iter_link_attach() later if there are other conditions which may cause rcu_read_lock() or spin_lock() issues.

Since arm64 instructions are always little-endian, change the type of these two variables to __le32 * and call cpu_to_le32() to convert instruction to little-endian before writing it to memory. This is also in line with emit() which internally does cpu_to_le32(), too.

2022-08-10nvme-tcp: check if the queue is allocated before stopping itMaurizio Lombardi
When an error is detected and the host reconnects, the nvme_tcp_error_recovery_work() function is called and starts tearing down the io queues and de-allocating them; If at the same time the "nvme" process deletes the controller via sysfs, the nvme_tcp_delete_ctrl() gets called and waits until the nvme_tcp_error_recovery_work() finishes its job; then starts tearing down the io queues, but at this point they have already been freed and the mutexes are destroyed. Calling mutex_lock() against a destroyed mutex triggers a warning: [ 1299.025575] nvme nvme1: Reconnecting in 10 seconds...

2022-08-10perf inject jit: Ignore memfd and anonymous mmap events if jitdump presentBrian Robbins
Some processes store jitted code in memfd mappings to avoid having rwx mappings. These processes map the code with a writeable mapping and a read-execute mapping. They write the code using the writeable mapping and then unmap the writeable mapping. All subsequent execution is through the read-execute mapping. perf inject --jit ignores //anon* mappings for each process where a jitdump is present because it expects to inject mmap events for each jitted code range, and said jitted code ranges will overlap with the //anon* mappings. Ignore /memfd: and [anon:* mappings so that jitted code contained in /memfd: and [anon:* mappings is treated the same way as jitted code contained in //anon* mappings.
