2020-10-12ceph: encode inodes' parent/d_name in cap reconnect messageYan, Zheng
Since nautilus, MDS tracks dirfrags whose child inodes have caps in open file table. When MDS recovers, it prefetches all of these dirfrags. This avoids using backtrace to load inodes. But dirfrags prefetch may load lots of useless inodes into cache, and make MDS run out of memory. Recent MDS adds an option that disables dirfrags prefetch. When dirfrags prefetch is disabled. Recovering MDS only prefetches corresponding dir inodes. Including inodes' parent/d_name in cap reconnect message can help MDS to load inodes into its cache.

2020-10-12perf/core: Fix race in the perf_mmap_close() functionJiri Olsa
There's a possible race in perf_mmap_close() when checking ring buffer's mmap_count refcount value. The problem is that the mmap_count check is not atomic because we call atomic_dec() and atomic_read() separately. perf_mmap_close: ... atomic_dec(&rb->mmap_count); ... if (atomic_read(&rb->mmap_count)) goto out_put; <ring buffer detach> free_uid out_put: ring_buffer_put(rb); /* could be last */ The race can happen when we have two (or more) events sharing same ring buffer and they go through atomic_dec() and then they both see 0 as refcount value later in atomic_read(). Then both will go on and execute code which is meant to be run just once. The code that detaches ring buffer is probably fine to be executed more than once, but the problem is in calling free_uid(), which will later on demonstrate in related crashes and refcount warnings, like: refcount_t: addition on 0; use-after-free. ...

2020-10-12ALSA: hda: fix jack detection with Realtek codecs when in D3Kai Vehmanen
In case HDA controller becomes active, but codec is runtime suspended, jack detection is not successful and no interrupt is raised. This has been observed with multiple Realtek codecs and HDA controllers from different vendors. Bug does not occur if both codec and controller are active, or both are in suspend. Bug can be easily hit on desktop systems with no built-in speaker. The problem can be fixed by powering up the codec once after every controller runtime resume. Even if codec goes back to suspend later, the jack detection will continue to work. Add a flag to 'hda_codec' to describe codecs that require this flow from the controller driver. Modify __azx_runtime_resume() to use pm_request_resume() to make the intent clearer. Mark all Realtek codecs with the new forced_resume flag.

2020-10-12tomoyo: Loosen pathname/domainname validation.Tetsuo Handa
Since commit e2dc9bf3f5275ca3 ("umd: Transform fork_usermode_blob into fork_usermode_driver") started calling execve() on a program written in a local mount which is not connected to mount tree, tomoyo_realpath_from_path() started returning a pathname in "$fsname:/$pathname" format which violates TOMOYO's domainname rule that it must start with "<$namespace>" followed by zero or more repetitions of pathnames which start with '/'. Since $fsname must not contain '.' since commit 79c0b2df79eb56fc ("add filesystem subtype support"), tomoyo_correct_path() can recognize a token which appears '/' before '.' appears (e.g. proc:/self/exe ) as a pathname while rejecting a token which appears '.' before '/' appears (e.g. exec.realpath="/bin/bash" ) as a condition parameter. Therefore, accept domainnames which contain pathnames which do not start with '/' but contain '/' before '.' (e.g. <kernel> tmpfs:/bpfilter_umh ).

2020-10-11Convert trailing spaces and periods in path componentsBoris Protopopov
When converting trailing spaces and periods in paths, do so for every component of the path, not just the last component. If the conversion is not done for every path component, then subsequent operations in directories with trailing spaces or periods (e.g. create(), mkdir()) will fail with ENOENT. This is because on the server, the directory will have a special symbol in its name, and the client needs to provide the same.

2020-10-11Merge branch 'bpf, sockmap: allow verdict only sk_skb progs'Alexei Starovoitov
John Fastabend says: ==================== This allows a sockmap sk_skb verdict programs to run without a parser. For some use cases, such as verdict program that support streaming data or a l3/l4 proxy that does not use data in packet, loading the nop parser 'return skb->len' is an extra unnecessary complexity. With this series we simply call the verdict program directly from data_ready instead of bouncing through the strparser logic. Patches 1,2 do the lifting on the sockmap side then patches 3,4 add the selftests. This applies on top of the series here, sockmap/sk_skb program memory acct fixes https://patchwork.ozlabs.org/project/netdev/list/?series=206975 it will apply without the above series cleanly, but will have an incorrect memory accounting causing a failure in ./test_sockmap. I could have left it so the series passed without above series, but it seemed odd to have it out there and then require yet another patch to fix it up here. Thanks. --- ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2020-10-11bpf, selftests: Add three new sockmap tests for verdict only programsJohn Fastabend
Here we add three new tests for sockmap to test having a verdict program without setting the parser program. The first test covers the most simply case, sender proxy_recv proxy_send recv | | | | verdict -----+ | | | | | +----------------+ +------------+ We load the verdict program on the proxy_recv socket without a parser program. It then does a redirect into the send path of the proxy_send socket using sendpage_locked(). Next we test the drop case to ensure if we kfree_skb as a result of the verdict program everything behaves as expected. Next we test the same configuration above, but with ktls and a redirect into socket ingress queue. Shown here tls tls sender proxy_recv proxy_send recv | | | | verdict ------------------+ | | redirect_ingress +----------------+ Also to set up ping/pong test Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/160239302638.8495.17125996694402793471.stgit@john-Precision-5820-Tower
