2019-10-23dmaengine: cppi41: Fix cppi41_dma_prep_slave_sg() when idleTony Lindgren1-1/+20
Yegor Yefremov <[email protected]> reported that musb and ftdi uart can fail for the first open of the uart unless connected using a hub. This is because the first dma call done by musb_ep_program() must wait if cppi41 is PM runtime suspended. Otherwise musb_ep_program() continues with other non-dma packets before the DMA transfer is started causing at least ftdi uarts to fail to receive data. Let's fix the issue by waking up cppi41 with PM runtime calls added to cppi41_dma_prep_slave_sg() and return NULL if still idled. This way we have musb_ep_program() continue with PIO until cppi41 is awake.

2019-10-23lib/vdso: Make clock_getres() POSIX compliant againThomas Gleixner1-4/+5
A recent commit removed the NULL pointer check from the clock_getres() implementation causing a test case to fault. POSIX requires an explicit NULL pointer check for clock_getres() aside of the validity check of the clock_id argument for obscure reasons. Add it back for both 32bit and 64bit. Note, this is only a partial revert of the offending commit which does not bring back the broken fallback invocation in the the 32bit compat implementations of clock_getres() and clock_gettime().

2019-10-23fuse: flush dirty data/metadata before non-truncate setattrMiklos Szeredi1-0/+13
If writeback cache is enabled, then writes might get reordered with chmod/chown/utimes. The problem with this is that performing the write in the fuse daemon might itself change some of these attributes. In such case the following sequence of operations will result in file ending up with the wrong mode, for example: int fd = open ("suid", O_WRONLY|O_CREAT|O_EXCL); write (fd, "1", 1); fchown (fd, 0, 0); fchmod (fd, 04755); close (fd); This patch fixes this by flushing pending writes before performing chown/chmod/utimes.

2019-10-23scripts/nsdeps: use alternative sed delimiterJessica Yu1-1/+1
When doing an out of tree build with O=, the nsdeps script constructs the absolute pathname of the module source file so that it can insert MODULE_IMPORT_NS statements in the right place. However, ${srctree} contains an unescaped path to the source tree, which, when used in a sed substitution, makes sed complain: ++ sed 's/[^ ]* *//home/jeyu/jeyu-linux\/&/g' sed: -e expression #1, char 12: unknown option to `s' The sed substitution command 's' ends prematurely with the forward slashes in the pathname, and sed errors out when it encounters the 'h', which is an invalid sed substitution option. To avoid escaping forward slashes ${srctree}, we can use '|' as an alternative delimiter for sed instead to avoid this error.

Users reported a v5.3 performance regression and inability to establish huge page mappings. A revised version of the ndctl "dax.sh" huge page unit test identifies commit 23c84eb78375 "dax: Fix missed wakeup with PMD faults" as the source. Update get_unlocked_entry() to check for NULL entries before checking the entry order, otherwise NULL is misinterpreted as a present pte conflict. The 'order' check needs to happen before the locked check as an unlocked entry at the wrong order must fallback to lookup the correct order.

2019-10-23opp: Reinitialize the list_kref before adding the static OPPs againViresh Kumar1-0/+7
The list_kref reaches a count of 0 when all the static OPPs are removed, for example when dev_pm_opp_of_cpumask_remove_table() is called, though the actual OPP table may not get freed as it may still be referenced by other parts of the kernel, like from a call to dev_pm_opp_set_supported_hw(). And if we call dev_pm_opp_of_cpumask_add_table() again at this point, we must reinitialize the list_kref otherwise the kernel will hit a WARN() in kref infrastructure for incrementing a kref with value 0.

2019-10-22bpf: Fix use after free in bpf_get_prog_nameDaniel Borkmann1-1/+1
There is one more problematic case I noticed while recently fixing BPF kallsyms handling in cd7455f1013e ("bpf: Fix use after free in subprog's jited symbol removal") and that is bpf_get_prog_name(). If BTF has been attached to the prog, then we may be able to fetch the function signature type id in kallsyms through prog->aux->func_info[prog->aux->func_idx].type_id. However, while the BTF object itself is torn down via RCU callback, the prog's aux->func_info is immediately freed via kvfree(prog->aux->func_info) once the prog's refcount either hit zero or when subprograms were already exposed via kallsyms and we hit the error path added in 5482e9a93c83 ("bpf: Fix memleak in aux->func_info and aux->btf"). This violates RCU as well since kallsyms could be walked in parallel where we could access aux->func_info. Hence, defer kvfree() to after RCU grace period. Looking at ba64e7d85252 ("bpf: btf: support proper non-jit func info") there is no reason/dependency where we couldn't defer the kvfree(aux->func_info) into the RCU callback.

After commit 309b66970ee2 ("net: openvswitch: do not free vport if register_netdevice() is failed."), the duty to destroy vport is offloaded from the driver OTOH, which ends up in the memory leak reported. It is fixed by releasing vport unless device is registered successfully. To do that, the callback assignment is defered until device is registered.
