Pull s390 updates from Heiko Carstens: "The main thing in this merge is the defense for the Spectre vulnerabilities. But there are other updates as well, the changes in more detail: - An s390 specific implementation of the array_index_mask_nospec function to the defense against spectre v1 - Two patches to utilize the new PPA-12/PPA-13 instructions to run the kernel and/or user space with reduced branch predicton. - The s390 variant of the 'retpoline' spectre v2 defense called 'expoline'. There is no return instruction for s390, instead an indirect branch is used for function return The s390 defense mechanism for indirect branches works by using an execute-type instruction with the indirect branch as the target of the execute. In effect that turns off the prediction for the indirect branch. - Scrub registers in entry.S that contain user controlled values to prevent the speculative use of these values. - Re-add the second parameter for the s390 specific runtime instrumentation system call and move the header file to uapi. The second parameter will continue to do nothing but older kernel versions only accepted valid real-time signal numbers. The details will be documented in the man-page for the system call. - Corrections and improvements for the s390 specific documentation - Add a line to /proc/sysinfo to display the CPU model dependent license-internal-code identifier - A header file include fix for eadm. - An error message fix in the kprobes code. - The removal of an outdated ARCH_xxx select statement" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/kconfig: Remove ARCH_WANTS_PROT_NUMA_PROT_NONE select s390: introduce execute-trampolines for branches s390: run user space and KVM guests with modified branch prediction s390: add options to change branch prediction behaviour for the kernel s390/alternative: use a copy of the facility bit mask s390: add optimized array_index_mask_nospec s390: scrub registers on kernel entry and KVM exit s390/cio: fix kernel-doc usage s390/runtime_instrumentation: re-add signum system call parameter s390/cpum_cf: correct counter number of LAST_HOST_TRANSLATIONS s390/kprobes: Fix %p uses in error messages s390/runtime instrumentation: provide uapi header file s390/sysinfo: add and display licensed internal code identifier s390/docs: reword airq section s390/docs: mention subchannel types s390/cmf: fix kerneldoc s390/eadm: fix CONFIG_BLOCK include dependency

由 Chuck Lever 提交于
A single NFSv4 WRITE compound can often have three operations: PUTFH, WRITE, then GETATTR. When the WRITE payload is sent in a Read chunk, the client places the GETATTR in the inline part of the RPC/RDMA message, just after the WRITE operation (sans payload). The position value in the Read chunk enables the receiver to insert the Read chunk at the correct place in the received XDR stream; that is between the WRITE and GETATTR. According to RFC 8166, an NFS/RDMA client does not have to add XDR round-up to the Read chunk that carries the WRITE payload. The receiver adds XDR round-up padding if it is absent and the receiver's XDR decoder requires it to be present. Commit 193bcb7b ("svcrdma: Populate tail iovec when receiving") attempted to add support for receiving such a compound so that just the WRITE payload appears in rq_arg's page list, and the trailing GETATTR is placed in rq_arg's tail iovec. (TCP just strings the whole compound into the head iovec and page list, without regard to the alignment of the WRITE payload). The server transport logic also had to accommodate the optional XDR round-up of the Read chunk, which it did simply by lengthening the tail iovec when round-up was needed. This approach is adequate for the NFSv2 and NFSv3 WRITE decoders. Unfortunately it is not sufficient for nfsd4_decode_write. When the Read chunk length is a couple of bytes less than PAGE_SIZE, the computation at the end of nfsd4_decode_write allows argp->pagelen to go negative, which breaks the logic in read_buf that looks for the tail iovec. The result is that a WRITE operation whose payload length is just less than a multiple of a page succeeds, but the subsequent GETATTR in the same compound fails with NFS4ERR_OP_ILLEGAL because the XDR decoder can't find it. Clients ignore the error, but they must update their attribute cache via a separate round trip. As nfsd4_decode_write appears to expect the payload itself to always have appropriate XDR round-up, have svc_rdma_build_normal_read_chunk add the Read chunk XDR round-up to the page_len rather than lengthening the tail iovec.

The time values in stat and inode may differ for overlayfs and stat time values are the correct ones to use. This is also consistent with the fact that fill_post_wcc() also stores stat time values. This means introducing a stat call that could fail, where previously we were just copying values out of the inode. To be conservative about changing behavior, we fall back to copying values out of the inode in the error case. It might be better just to clear fh_pre_saved (though note the BUG_ON in set_change_info). Signed-off-by: NAmir Goldstein <amir73il@gmail.com> Signed-off-by: NJ. Bruce Fields <bfields@redhat.com>

The values of stat->mtime and inode->i_mtime may differ for overlayfs and stat->mtime is the correct value to use when encoding getattr. This is also consistent with the fact that other attr times are also encoded from stat values. Both callers of lease_get_mtime() already have the value of stat->mtime, so the only needed change is that lease_get_mtime() will not overwrite this value with inode->i_mtime in case the inode does not have an exclusive lease.

A client that sends more than a hundred ops in a single compound currently gets an rpc-level GARBAGE_ARGS error. It would be more helpful to return NFS4ERR_RESOURCE, since that gives the client a better idea how to recover (for example by splitting up the compound into smaller compounds). This is all a bit academic since we've never actually seen a reason for clients to send such long compounds, but we may as well fix it. While we're there, just use NFSD4_MAX_OPS_PER_COMPOUND == 16, the constant we already use in the 4.1 case, instead of hard-coding 100. Chances anyone actually uses even 16 ops per compound are small enough that I think there's a neglible risk or any regression. This fixes pynfs test COMP6.

Al Viro discovered a bug in the removing of function probes where if it had a '*' at the beginning, it would fail to find any matches. That is, because it reset the glob search string to the the initial string with a "MATCH_END" type, instead of skipping the wildcard "*" it included it, where it would not match any functions because "*" was being treated as a normal character and not a wildcard one.

Al Viro discovered a bug in the glob ftrace filtering code where "*a*b" is treated the same as "a*b", and functions that would be selected by "*a*b" but not "a*b" are not selected with "*a*b". Add tests for patterns "*a*b" and "a*b*" to the glob selftest.

If a probe is attached to a static function that is in multiple files with the same name, removing it by name will remove all instances: # grep jump_label_unlock set_ftrace_filter jump_label_unlock:traceoff:unlimited jump_label_unlock:traceoff:unlimited # echo '!jump_label_unlock:traceoff' >> set_ftrace_filter # grep jump_label_unlock set_ftrace_filter # But the loop in reset_ftrace_filter will try to remove multiple instances multiple times. If this happens the second time will error and cause the test to fail. At each iteration of the loop, check to see if the probe being removed still exists.

If a function probe in set_ftrace_filter belongs to a module, it will contain the module name. Like: wmi_query_block [wmi]:traceoff:unlimited But writing: '!wmi_query_block [wmi]:traceoff' > set_ftrace_filter will cause an error. We still need to write: '!wmi_query_block:traceoff' > set_ftrace_filter Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: NSteven Rostedt (VMware) <rostedt@goodmis.org>

Al Viro reported: For substring - sure, but what about something like "*a*b" and "a*b"? AFAICS, filter_parse_regex() ends up with identical results in both cases - MATCH_GLOB and *search = "a*b". And no way for the caller to tell one from another. Testing this with the following: # cd /sys/kernel/tracing # echo '*raw*lock' > set_ftrace_filter bash: echo: write error: Invalid argument With this patch: # echo '*raw*lock' > set_ftrace_filter # cat set_ftrace_filter _raw_read_trylock _raw_write_trylock _raw_read_unlock _raw_spin_unlock _raw_write_unlock _raw_spin_trylock _raw_spin_lock _raw_write_lock _raw_read_lock Al recommended not setting the search buffer to skip the first '*' unless we know we are not using MATCH_GLOB. This implements his suggested logic.

__unregister_ftrace_function_probe() will incorrectly parse the glob filter because it resets the search variable that was setup by filter_parse_regex(). Al Viro reported this: After that call of filter_parse_regex() we could have func_g.search not equal to glob only if glob started with '!' or '*'. In the former case we would've buggered off with -EINVAL (not = 1). In the latter we would've set func_g.search equal to glob + 1, calculated the length of that thing in func_g.len and proceeded to reset func_g.search back to glob. Suppose the glob is e.g. *foo*. We end up with func_g.type = MATCH_MIDDLE_ONLY; func_g.len = 3; func_g.search = "*foo"; Feeding that to ftrace_match_record() will not do anything sane - we will be looking for names containing "*foo" (->len is ignored for that one).

Commit 0fbc0b67 ("cris: remove arch specific early DT functions") was a bit overzealous in removing the CRIS DT handling, and the complete contents of the Makefile was erased instead of just the line for the devicetree file. This lead to a complete link failure for all SoCs in the CRIS port due to missing symbols. Restore the contents except the line for the devicetree file.
